Description

one

The invention relates to the field of the preparation and use of a composite based on bitullo-polymeric emulsions used for the device of waterproofing, roofing coatings and anti-corrosion protection. Bitumen-polymer mixtures are known, including bitumen, acidol-mylonaph, caustic soda, liquid glass, aqueous dispersion of fluorine-containing carbon-chain thermoplastic and latex SKS.-65 Sh.

However, the above compositions have the disadvantage of high physicomechanical properties, especially adhesive strength to the substrate and stability at 1 ° temperatures.

The closest in technical support and the obtained effect to the claimed composition is a composition that includes bitumen, emulsifier, polyvinylpyrrolidone, corrosion inhibitor, synthetic latex and water 1.

However, the physicomechanical properties of the surface based on this composition are also not sufficiently high, for example, adhesion and weather resistance.

The purpose of this invention is to improve the physico-mechanical properties of the composition. The goal is achieved that the waterproofing composition, including bitumen, emulsifier, polyvinylpyrrolidone, synthetic latex, corrosion inhibitor and water, additionally contains a methylmethagrylate copolymer with chloroprene and a chlorohydrized amine adduct of diethalenemidriamine -1 with diglycidyldamanum in the following ratio of component and component:

Bitum100

Emulsifier 0.6-5

Synthetic latex5, -24

Corrosion inhibitor

Methyl methacrylate copolymer with chloroprene2-24

Chlorohydrated amine of diethylenetriamine adduct with dig icidyl-dianom2-10

Water 118-220.

The composition is prepared on special emulsifying masks-dispersants of periodic

or uninterrupted action. The preparation process is as follows:

In an emulsion machine, bitumen is dispersed in an aqueous solution of an emulsifier, which is pre-introduced with polyvinylpyrroldone and a corrosion inhibitor, is dosed in certain ratios.

The finished bitumen emulsion composition is mixed in rotary turbulent extractors in succession in the required proportions of a solution of synthetic latex, a solution of methyl methacrylate copolymer with chloroprene, a solution of chloro T1Diridine amine adduct of diethylene triamine with diglycidyldian until a homogeneous state is obtained.

The invention is illustrated by examples.
