The invention relates to compositions of raw mix for the production finishing and decorative building products.

Famous raw mix for the production and finishing of decorative products based on traditional binders cement, gypsum, clay and other

However, all these compounds do not have a Spa effect, that is not the source of the selection of ions of iodine, bromine, magnesium - elements necessary for the life of the human organism.

It is known that products such as slabs, mortars based on magnesia cement, consisting of caustic magnesite, bischofite and sawdust, are a source of saturated ambient air ions of magnesium and other elements and are recommended for use in aeroionotherapy. This effect is achieved through the use of a mixture of an aqueous solution of bischofite (MgCl2·6H2O), the Foundation of which is magnesium chloride. Bischofite was recommended by the Ministry of health of the USSR as a balneologic stuff means.

Known construction mixture consisting of caustic magnesite, an aqueous solution of magnesium chloride, a cellulose-containing filler plant origin, such as sawdust, and expanded perlite (RF Patent No. 2090535, 20.09.97, bull. No. 26).

This mixture has a health effect that is the source of a selection of ions of bromine, magnesium - elements necessary for the life of the human organism.

In areas with products from this mixture, a marked beneficial effect on the surrounding air due to the stabilization of temperature and humidity, and saturation of air ions of magnesium and other trace elements. However, a significant effect of saturation aerons bromine, magnesium and, in particular, iodine to achieve for a long time could not. In addition, when using an aqueous solution of magnesium chloride obtained by chemical means, instead of natural bischofite operational characteristics of the mixture are retained, but the air is not saturated with ions of magnesium, bromine and iodine.

It is known that iodine is a volatile substance. Therefore, when introducing it into the mix effect separation of ions of iodine is only valid for a short period of time. Because of this, substances or solutions containing iodine, in mortar was not used. The provision of an increased excretion of ions of magnesium and bromine for the desired gain balneological effect is possible due to the significant increase in the content of bischofite solution in the mixture. However, the increase in the content of bischofite solution leads to a degradation of the performance - cracking products from this mixture, so it's not p is Antiques (Technical encyclopedia, t, edited by Lkkaracan, editorial technical encyclopedias and dictionaries, M., 1939, str).

The closest technical solution mixture is a mixture containing magnesia binder (caustic magnesite and an aqueous solution of magnesium chloride) and organic cellulose filler - wood sawdust. (Nanetashvili J. C. "Building materials made of wood-cement compositions"- L., 1990, str.)

The most widely as an aqueous solution of magnesium chloride is used an aqueous solution of bischofite (MgCl2·6H2O) GOST 7759-73. (Nanetashvili J. C. "Building materials made of wood-cement compositions"- L., 1990, str.)

Thus, the mixture consists of caustic magnesite, sawdust, an aqueous solution of bischofite. The disadvantage of this mixture is that this mixture does not have a Spa effect with increased allocation ions of iodine, magnesium and bromine over a long period of time while maintaining the basic performance characteristics, such as strength, trainerstation.

The objective of the invention is to create a new composition of raw mix for the production finishing and decorative building products with Spa effect with an increased allocation of the iodine ions and/or magnesium and bromine over a long period of the time while maintaining the basic performance characteristics, for example strength, trainerstation.

The technical result from the use of the invention is to provide compositions of the raw material mixture having as essential performance characteristics, and its health effect for a long period of time of operation of the products made from these mixtures.

This is achieved by the fact that in the raw material mixture according to the first variant, containing caustic magnesite, sawdust, water bischofite solution, further added Iodinol, pre-dissolved in an aqueous solution of bischofite, in the following ratio of components in volumetric parts:

An aqueous solution of bischofite0,7-1,0
Caustic magnesite1,0-1,5
Sawdust2,0-3,5
The Iodinol0,3-0,6

The Iodinol - liquid dark blue color with a characteristic odor, foaming when shaken. The composition of Iodinol - crystalline iodine, potassium iodide, polyvinyl alcohol, water. The main active ingredient of Iodinol is molecular iodine, which has antiseptic properties. He has a bactericidal effect.

This is achieved by the fact that the raw material mixture containing caustic magician is ESET, sawdust, an aqueous solution of bischofite, Iodinol, includes in addition to the crystals of the mineral carnallite size from 2 mm to 10 mm 0,25-0,40 ABC

This is achieved by the fact that on the second version of the raw mixture containing caustic magnesite, sawdust, an aqueous solution of bischofite, further comprises crystals of the mineral carnallite size from 2 mm to 10 mm, introduced after caustic magnesite, sawdust and water solution bischofite, in the following ratio of components, bulk parts:

An aqueous solution of bischofite0,7-1,0
Caustic magnesite1,0-1,5
Sawdust2,0-3,5
The crystals of the mineral carnallite0,25-0,40

As is known, the level of iodine content in the atmosphere of an average strip of Russia is significantly below the required standards. Therefore, entered into the composition of the raw mix Iodinol due to additional allocation ions of iodine increases the amount of iodine in the atmosphere of the rooms finished products made from mixtures containing Iodinol.

When creating a mixture in the first embodiment is used the medication Iodinol (iodinolum) (set OS-3 per ABC. No. 70.529.38).

With the introduction of the mixture of Iodinol in the amount of 0,3-0,6 about jamnik parts the density of an aqueous solution of bischofite corresponds to the density of 1.12-1.18 g/cm 3. The increase in the number of Iodinol reduces the density of bischofite solution and, consequently, degrades the performance properties of the mixture, and reducing the number of Iodinol less than 0.3 parts by volume not give the desired effect of increasing the separation of ions of iodine.

The excessive secretion of ions of magnesium and bromine is achieved by the fact that in the raw material mixture further added carnallite crystals with a size from 2 mm to 10 mm 0,25-0,4 parts.

As you know, the magnesium chloride in nature is the basis of such minerals as bischofite and carnallite, solutions which are used to obtain magnesia cement. These solutions serve as a source of ions of magnesium and bromine.

When preparing the raw material mixture to 65% of the injected solution of magnesium chloride from the solution participate in the reaction with caustic magnesite. And only the remaining amount can participate in the process of ionization.

Introduction the composition of the mixture is additionally put into the form of crystals can significantly increase the effect of air ionization due to the fact that the carnallite crystals have a lower rate of emission of ions than the aqueous solution of carnallite. In addition, carnallite in the form of crystals has a lower reactivity than the aqueous solution, it is practically not involved in the chemical reaction with caustic magnesite and about the remains in the form of crystals in the hardened mass.

With the introduction of the carnallite crystals in the amount of less than 0.25 parts by volume, a slight increase in aarnisalo, and more than 0,4 parts deteriorate performance. The crystal size of less than 2 mm under stirring absorbed by bischofite solution, and the crystals larger than 10 mm reduce the strength of the mixture.

As part of carnallite are isomorphic admixture of bromine in the amount of 0.2%. Bromine, not as a crystalline substance, distributed throughout the volume of material carnallite in intergranular spaces. In addition, carnallite is a complex salt containing mechanical impurities other salts, clay substances and rocks, formed over a substantial period of time. Mechanical impurities, clay material and rock are the shell, which creates a braking effect to highlight bromine through the smallest pores. Given the hygroscopicity of carnallite in the premises in which the product of the proposed mix, you can increase or decrease the humidity to increase or decrease the speed of separation of the bromine. The number of bromine 0.2% in the carnallite is not low, since its release is in the form of ions.

From the proposed mix released batch of tiles, which is used for the manufacture of wall panels, elements of p is chetcuti partitions, desktop products, etc. These products are used in children's entertainment rooms, bedrooms, halls of activities with the aim of creating a healthy atmosphere. They are recommended for use in workplaces with computers and other electronic equipment to enhance content in the air of negative ions. The table below shows the physico-mechanical characteristics of the products of the proposed mixture.

The achievement of the task is carried out by the methods of obtaining the raw material mixture.

An important distinguishing feature is that the constituent Iodinol pre-mixed with an aqueous solution of bischofite.

The introduction of Iodinol in the composition of the raw mix as a stand-alone component, does not increase the duration of excretion of ions of iodine. The iodine in the solution of polyvinyl alcohol, easily evaporates. Inhibitory effect separation of ions of iodine is observed only when the seat reservation dissolution of Iodinol in aqueous solution bischofite. Probably, the high density of the solution and the presence of soluble salt MgCl2creates a braking effect.

Mixing time of Iodinol with an aqueous solution of bischofite in for 1 minute is optimal for this process.

A distinctive feature is that the constituent crystals of the mineral carnallite with sizes from 2 to 10 mm add immediately after final mixing of the main components of the mixture and stirred no more than 1.5 minutes.

Mixing time for a period of not more than 1.5 minutes is optimal is determined visually depending on the volume of the mixture.

An important feature in obtaining the raw material mixture, the second option is that the constituent crystals of the mineral carnallite size from 2 mm to 10 mm add immediately after final mixing of the main components of the mixture and stirred for a period of not more than 1.5 minutes.

Obtaining the raw material mixture can be carried out on known equipment for the preparation of mixtures, for example in the mixer SB 162.

The resulting raw mixture to create a new material, conventionally called "AZ-Salt".

Used for raw mix raw materials are not scarce. Articles obtained from this mixture, non-flammable, are not the source of air pollution is acratech premises.

The proposed mixture compositions intended for the manufacture of cladding and decorative building products used in physical therapy offices, hospitals, and residential areas, and create rooms with artificial climate.

These attributes make the proposed solution from the prototype and determine compliance with this decision, the requirements of the invention.
