Waterproofing composition for coating
(57) Abstract:Usage: paints and coatings industry, namely to protect foundations, pipelines and roofs from the effects of the atmosphere, water, aqueous solutions of salts, acids and alkalis. The inventive waterproofing composition for coating comprising, by wt.%: chlorosulphurized polyethylene 13-17,5, mineral filler of 4.05-8,9, a mixture of 1-aminoethylaminomethyl-2-heptadecyl-2-imidazoline with monoamide oleic acid (Olaza") 0,2-0,4, styrolene-indene resin 12,5-16,8, epoxygenase resin 0,8-1,2, rubber crumb of 2.9 to 7.4, organic solvent - rest. table 2. The invention relates to paints, varnishes and lacquers, and in particular to compositions based on chlorosulfonated polyethylene (HCPE) for waterproofing and anticorrosive coatings of pipelines, foundations, roofs.Known for bitumen mastic for insulation of concrete, reinforced concrete, steel structures. However, coatings based on them are low-heat resistance and cold resistance /1/.The closest in technical essence and the achieved result to the claimed invention is a known compound for Crowell is. what, however, coverage based on the known composition of the lack of weather-, Talosto and chemical resistance in aggressive environments.An object of the invention is to increase teplota-, chemical - and weather resistance of the coating, improve its physical-mechanical properties and increase the solids of the composition, which allows to significantly reduce the number of deposited layers forming the coating, while maintaining water resistance.The technical result is achieved in that the waterproofing composition comprising chlorosulphurized polyethylene, mineral filler, curing agent, an organic solvent, characterized in that as a hardener it contains "Olaza", which is a mixture of 1-aminoethylaminomethyl-2-heptadecyl-2-imidazoline with monoamide oleic acid in a mass ratio (9:1), respectively, and additionally styrolene-indene resin, epoxygenase resin and rubber crumb in the following ratio, wt.Chlorosulphurized polyethylene 13-17,5
Stiralnaya resin 12,5-16,8
Epoxygenase resin of 0.8-1.2
Crumb rubber is 2.9 to 7.4
A mixture of 1-aminoethylaminomethyl-2-heptadecyl-ASCII solvent Else
In the composition of the invention use the following industrially produced components.Chlorosulphurized polyethylene, HSPA-20 on THE other 6-01-1-438-91; HSPA-20"AND" beyond 6-55-9-90; HSPA-M on THE other 6-01-1-415-90 produced in the form of elastic scales.As a hardener "Olaza mix - 1-aminoethylaminomethyl-2-heptadecyl-2-imidazoline with monoamide oleic acid at the ratio (9:1) wt. 'clock in accordance with THE-6-01-03-71-87, representing methodoloy mixture. "Olaza" does the composition of not only the role of promoter and inhibitor, and allows to obtain a heat-resistant coating with a high protective properties.Styrolene-indene resin, a petroleum resin in the form of plates on THE 14-6-89-73.Epoxygenase resin of low molecular weight brand ED-20 in accordance with GOST 10587-84.As a mineral filler you can use the micro-talc, marshalite, silica, etc.Crumb rubber is also an active filler, improve the physical and mechanical properties of the coating, and represents a departure rubber industry in the form of scrap vulcanized rubber based on various synthetic rubbers, the crushing is, solvent and otherThe composition is prepared as follows: HSPA dissolved in an organic solvent for 4-6 h at 60oC, the resulting varnish 15-22% concentration injected epoxygenase resin, for example, ED-20 and dissolved under stirring for 15-20 minutes until smooth. Separately prepare 10-50% solution "Olusola in an organic solvent.Before use of the composition in the mixture based on ASPA and epoxygenase resin under stirring enter styrolene-indene resin, after complete dissolution of the added rubber crumb, mineral filler, then 10-50% solution "Olusola" are thoroughly mixed to a homogeneous state. The viability of the composition is not more than two days. It is applied to the surface either manually filling and then leveled with a spatula or reklami and mechanized for 3-4 hours with interlayer drying at 15-20oC for 2-3 h and dried prior to commissioning within 3-5 days.In table. 1 presents the formulation of the proposed waterproofing compositions in table.2 illustrate the properties of coatings based on it. Waterproofing composition for coating comprising chlorosulphurized polyethylene, mineral n is it "Olaza", representing a mixture of 1-aminoethylaminomethyl-2-heptadecyl-2-imidazoline with monoamide oleic acid in a mass ratio of 9 to 1, respectively, and additionally styrolene-indene resin, epoxygenase resin and rubber crumb in the following ratio, wt.Chlorosulphurized polyethylene 13,0 17,5
Styrolene-indene resin 16,8 12,5
Epoxygenase resin 0,8 1,2
Crumb rubber 2,9 7,4
Olaza 0,2 0,4
Mineral filler of 4.05 8,9
