The invention relates to the processing of polyvinyl chloride (PVC) through the dispersion, in particular the production of highly filled plastisols used for the manufacture of protective coatings in the automotive industry, as anti-corrosion coating of internal surfaces of metal structures.

A method of obtaining PVC plastisol, including PVC, plasticizer, bentonite, stabilizer, polietilenglikolja derived oleic acid [A.S. USSR №804671, CL C08L 27/06, 1981].

The disadvantage of plastisol obtained in this way is a low adhesion to the metal surface.

A method of obtaining highly filled plastisol comprising emulsion PVC, di-2-ethylhexylphthalate, ether phosphoric acid, oligopyrroles, white spirit, kaolin, bentonite, oligoribonucleotide, Gidropress [RF Patent №2089572, MKI 6 C08L 27/06, SC 13/02 // (SC 13/02, 3:22, 3:24, 3:36, 5:01, 5:10, 5:14, 5:15, 5:205)].

Disadvantages plastisol obtained in this way are low: the degree of thixotropic recovery patterns after the application of shear deformation and extrusion of plastisol. While the vertical sections are formed nodules and streaks.

The closest is a method of obtaining highly filled plastisol PVC-based [RF Patent №2098437, MKI 6 C08L 27/0, SC 13/02 // (SC 13/02, 3:22, 5:01, 5:098, 5:10, 5:14)]. Plastisol is obtained by mixing the following ingredients, mass:

Polyvinyl chloride100
Di(2-ethylhexyl)phthalate80-100
Triethyleneglycoldinitrate40-60
Of cumene hydroperoxide0,4-1,2
White spirit20-25
Kaolin160-220
Calcium stearate3-6

Disadvantages plastisol obtained in this way are low: the degree of thixotropic recovery patterns after the application of shear deformation and extrusion, as well as the lack of resistance. The presence of a solvent white spirit in the composition of the PVC plastisol leads to high pozarovzryvobezopasnost in the coating on the base.

The task of the invention is to develop a method of producing highly filled PVC plastisol coatings with enhanced: degree of recovery thixotropic structure posibiloity shear deformation, extrusion, flame retardancy, tensile strength.

The technical result is to increase: the degree of thixotropic recovery patterns after the application of shear deformation, extrusion, flame resistance, tensile strength PVC plastisol.

The technical result is achieved in that a method of obtaining a highly filled plastisol PVC-based includes sequential introduction and mixing in a mixer di(2-ethylhexyl)phthalate, cumene cumene, half of a given amount of kaolin, calcium stearate, polyvinyl chloride and the remaining quantity of kaolin, characterized in that before the introduction of polyvinyl chloride in the composition is optionally administered hecatoncheires oligourethanes, diatomite and phosphate hydraulic fluid mark DALY-4, and after the remaining amount of the kaolin type polysulfide oligomer is a liquid Thiokol mark II with a mass fraction of SH-groups of 1.7 to 2.6% and molecular weight of 2100 in the following ratio components massc:

Polyvinyl chloride100
Di(2-ethylhexyl)phthalate80-100
Hecatoncheires of oligourethane is relat 40-60
Of cumene hydroperoxide0,4-1,2
Kaolin160-180
Calcium stearate3-6
Polysulfide oligomer1.5 to 2.5
Diatomite3-5
Phosphate hydraulic fluid mark DALY-42-7

While diatomaceous earth increases the thixotropic properties of the compositions due to physical interaction with the polymer matrix. Improving the fire resistance of the cured PVC plastisol due to the fact that in the presence of diatomite when exposed to an open flame produces a larger volume of the coke mass, with the insulating barrier effect. The introduction of the PVC plastisol structuring additive - polysulfide oligomer can significantly reduce the amount of stains and provide ravnoudalennostj applied to protect the surface of the PVC plastisol. This is because the curing polysulfide oligomer with the formation of cross-linked material starts at a lower temperature than the gelatinization PVC plastic the La, flowing at the temperature of 120-130°C. the Specified allows you to IntenseDebate the beginning of the process of structuring coatings methods airless spray. In addition, the interaction of cumene hydroperoxide with the polysulfide oligomer promotes education in the system of a large number of radicals, which leads to an increase in the degree of transformation in the polymer matrix of multicomponent plastisol. The presence in the composition of the PVC plastisol hecatoncheires of oligoamenorrhea and polysulfide oligomer promotes the formation of interpenetrating nets and, as a consequence, leads to an increase in the content of gel-fraction. Introduction to PVC-plastisol phosphate hydraulic fluid ngj-4, which is a mixture of CNIL and arylphosphate with additives, allows to improve the fire resistance of materials. The absence in the PVC plastisol solvent white spirit greatly increases fire and explosion safety of the coating process.

When carrying out the claimed invention PVC-plastisol has a higher rate of recovery thixotropic structure and extrusion, as well as increased resistance of the coating.

As can be seen from the table, when the content of di(2-ethylhexyl)phthalate less than 80 mass deteriorates the processability of the composition. The increase in the content of di(2-what tygacil)phthalate more than 100 mass leads to decrease: the degree of recovery of thixotropic properties, tensile strength and oxygen index.

Use hecatoncheires of oligoamenorrhea fewer than 40 mass affects the processability of the composition, reduces the adhesion strength of connection with the ground layer and the tensile strength. The increase in the content hecatoncheires of oligoamenorrhea over 60 mass leads to a decline in the rate of recovery thixotropic properties and flow index.

When the content of cumene hydroperoxide in quantities of less than 0.4 mass reduced depth transformation of the functional groups of the components involved in the formation of the polymer matrix. The use of cumene hydroperoxide in the amount of more than 1.2 mass contributes to the intensification of the processes of degradation of the cured PVC plastisol in conditions of atmospheric aging.

When the content of kaolin in fewer than 160 mass decrease the degree of recovery of thixotropic properties, oxygen index and increases the runoff of the composition. The increase in the content of kaolin over 180 mass leads to deterioration of processing AIDS compositions and increase extrusion process.

The use of calcium stearate in the amount of less than 3 mass leads to a decrease in the degree of thixotropic recovery is waist. When the content of calcium stearate in the amount of more than 6 mass increases the viscosity and extrusion, deteriorating the processability of the composition.

When using the content of polysulfide oligomer in an amount of less than 1.5 mass increases runoff PVC-plastisol when applied, reduces the degree of recovery tixotropic properties and the index of the current songs. The increase in the content of polysulfide oligomer, more than 2.5 mass leads to decrease in tensile strength and oxygen index.

The use of diatomaceous earth in the amount of less than 3 mass leads to the diminution of course, the degree of recovery of thixotropic properties and the oxygen index, the increase in runoff PVC plastisol. When the content of the diatomaceous earth in the amount of more than 5 mass deteriorates the processability of the composition, reduced oxygen index.

The use of phosphate hydraulic fluid mark DALY-4 in less than 2 mass leads to a decrease of the oxygen index. When using phosphate hydraulic fluid more than 7 mass increases microphase separation in PVC-plastisols and decreases the tensile strength of solidified materials.

In the composition of the plastisols according to the invention uses the following components: polyvinyl chloride paste (GOST 14039-78); di(2-ethylhexylphthalate (GOST 8728-88); hecatoncheires oligourethanes - product manufactured by Sartomer No. CN-975 with a viscosity of 0.51 PA·s (at 60°C) and a density of 1.19 g/ml (60°C); of cumene hydroperoxide PIPERIS (TU 34.402.62-121-90); calcium stearate C-17 (TU 6-09-4104-75); polysulfide oligomer is a liquid Thiokol mark II (GOST 12812-80) with a mass fraction of SH-groups of 1.7 to 2.6% and molecular weight of 2100; diatomite (TU 5761-001-25310144-99) is a light, porous rocks from white to yellowish-grey with average density, varying from 0.15 to 0.6 g/cm3. Diatomite 96% consists of water silica (opal) General formula SiO2·nH2O); phosphate hydraulic fluid (composition: dibutyltin 9-19%, tributyl phosphate 1.0 to 1.5%additive 2N 0,5-1,0, polybutylmethacrylate 5-7%) with the following characteristics: flash - 168-174°C, acid number, KOH/1 g - 0,10-0,17 mg, density at 20°C of 1.05-1.07 g/cm3, kinematic viscosity at 20°C and 5.2 to 6.5 cSt, the refractive index 1,4592-1,4599.
