The invention relates to a method of monolithic deposition of insulating and/or fire-retardant mass on a surface and device for implementing the method.

It is known that asbestos is harmful to health and therefore in construction, primarily for closed internal spaces should be avoided. On the other hand, building materials containing asbestos, fire-resistant, which makes intuitive multi-layer application in the form of a solid building elements, as well as in the form of a pour or spray liquid of the main substances (materials). In addition, asbestos is a poor conductor of heat, which provides izvestni the search for substitutes, which first of all show similar high resistance. Such substances with similar high flame-retardant properties and are, for example, vermiculite and perlite, which also does not irritate the skin and when handling them require no special protection, and also create a good sound and heat insulation. For isolation is used, for example, mineral wool, etc., which during processing also requires only a small protective measures.

Despite intensive attempts still failed to produce insulating and/or fire-retardant mass with the above materials, which can be applied cast on a smooth surface without bonding primer and without mechanical fasteners, such as plaster, applied by spraying (1,2).

The objective of the invention is to find a way to create a device that would allow the cast to put on a surface and/or fire-retardant mass.

This task is solved in that in the transport channel through pneumopathies creates mobile air volume, which is insulating and/or fireproofing material and hardener that fall with the volume of air is output introduced gaseous medium and a binder or adhesive. Created thus insulating and/or fire-retardant mass can integrally and firmly applied to the surface and maintains specific for insulating and/or fireproofing materials properties.

In particular, the volume of air is introduced at the beginning of the insulating and/or fireproofing material, and then separately preferably poroshkoobraznyj hardener.

Particularly suitable method according to the invention for the deposition of insulating and/or fireproofing material having a smaller specific gravity than that of the binder, as relatively easier insulating and/or fireproofing material can be transported in air volume, and a relatively heavier binder or relatively heavier glue is added later.

Suitable insulating and/or fireproofing materials are vermiculite, perlite or Rockwool.

As a binder can be applied adhesive, in particular a fire-retardant adhesive.

In the beginning of the process delay the inclusion of pneumopathies, start filing insulating and/or fireproofing material, compound or adhesive, preferably by means of a control device, in accordance the line acceleration, different due to the differences in specific gravities and different distances of places supply to the output nozzle of spray guns.

All the components after their phase acceleration have the same speed, namely the speed of the air volume, thus achieving a uniform transport components.

The device according to the invention differs in that pneumotonometer attached to its suction side to the end of the transport channel, which flows into at least one supply device for insulating and/or fireproofing material and hardener, and that pneumotonometer on his boot side is connected to the sleeve, the end of which is a spray gun, which flows into the sleeve for supplying gaseous pressure medium and the inlet line for the binder or glue. Insulating and/or fireproofing material and the curing agent is not blown through the transport channel, which would be impossible or difficult with other light materials due to their specific gravities, and are sucked into the moving air volume.

Transport channel preferably has at the other end of the regulating valve, which allows you to manage ku feeding device for insulating and/or fireproofing material and hardener. Thanks to the separate feeding of the mixed ratio may be changed at any time. Dosed returns can be made, for example, the feeding device hardener by means driven from the motor of the auger, and a feeding device for insulating and/or fireproofing material through pneumocandin.

To manage these feeding devices for insulating and/or fireproofing material and hardener, and a supply device for a binder or glue, and La control the supply of pressure medium and pneumomediastinum provided by the electronic control unit. This ensures that when a pre-selected amount of feed and a pre-selected mix ratio easy maintenance of the device at a constant result.

As can be seen from Fig. 1, pneumotonometer 2 is connected on one side with one end of the transport channel 1, and on the other side with the accession of 12. Transport channel 1 is at the other end of the regulating valve 16. Between the control valve 16 and pneumomediastinum 2 in the flow channel of the supply device 10, 11, respectively, for insulating and/or fireproofing material 3 and hardener 4. Return insulating the screw. From the joining of the 12 leads of the sleeve 13 is shown in Fig. 2 the gun nozzle 5 through which the sleeve 14 is injected, on the one hand, compressed air 7 from the device compressed air supply 15, and on the other hand, through line 20 and valve 19 binder or adhesive 8.

At the beginning of the operation switching the device starts pneumotonometer 2 through the control unit 9. Once the volume of the air control device 9 activates the power supply device 10 and the volume of air is constant, the number of insulating and/or fireproofing material 3, then with some time delay is activated feeding device 11, and a constant amount of hardener 4 also introduced into the mixture consisting of air and insulation and/or fire resistant material. Pneumotonometer 2 sucks air volume with insulating and/or fireproofing material 3 and hardener 4 and transports it to the gun nozzle 5. There again with some delay to it mixed with a binder or adhesive 8. Due to the differences in specific gravities of the insulating and/or fireproofing material 3, hardener 4 and a binder or adhesive 8 these individual components have different acceleration in the volume of air that WH devices at the beginning of the work results, the mixture injected from stoplooping exit 6 with a gaseous pressure medium, has from the outset a predetermined ratio of the components, i.e., from the beginning suitable for processing. When unplugging the device, the control device 9 controls shutdown of individual feeding devices and pneumopathies in reverse order, so in the end, leaving no usable waste.

For example, in the corresponding experiments on the manufacture of control surfaces for test programs according to Austrian Standards B 3800 and S 5104 used vermiculite with grain size from 3 to 6 mm, powder hardener and solvent free flame retardant adhesive company Burian GEZ. mbH & CO KG ("Burian-Steel-Brandschutzklappen"). The experiments showed that insulating and/or fire-retardant mass made from the above materials by the method according to the invention, has a fire resistance in accordance with class pozharoopasny F 90, high agreementamong properties in accordance with the class pozharoopasny F60, low smoke emission (class of smoke Q 1) and a small drop (class drop Tr 1), and Taya fire-retardant mass, it is established that they have along with good flame retardant and good sound and noise-attenuating properties and heat and gladitorium properties.
