Chlorosulfonated polyethylene-styrene butadiene rubber heat-insulation waterproof coating and preparation method thereof

Abstract

A chlorosulfonated polyethylene-styrene butadiene rubber heat-insulation waterproof coating is prepared from, by weight, 100 parts of a styrene butadiene rubber emulsion, 8-10 parts of a chloroprene rubber emulsion, 15-20 parts of hydroxyethyl methylacrylate, 8-10 parts of alkylresorcinol formaldehyde resin, 1-2 parts of hexakis(methoxymethyl)melamine, 3-5 parts of titanium dioxide, 3-5 parts of talcum powder, 30-40 parts of dimethyl carbonate, 4-6 parts of chlorinated polyethylene, 1-2 parts of sulfuric chloride, 0.5-1 part of benzoyl peroxide, 8-10 parts of pyridine, 1-2 parts of sodium tripolyphosphate, 2-3 parts of tributyl phosphate, 1-2 parts of Texanol, 0.5-1 part of 1,2-benzisothiazolin-3-one, 1-2 parts of hydroxymethyl cellulose, 8-10 parts of hollow glass beads and a proper amount of deionized water. The heat-insulation waterproof coating has the advantages of low cost, good heat insulation effect, good lighting degree, simple construction and good application prospect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-insulating and waterproof coating of chlorosulfonated polyethylene-styrene-butadiene rubber and a preparation method thereof. technical background [0002] Due to the sunlight, the temperature inside the building rises, which will increase the energy consumption of the air conditioner. In addition, industrial plants, prefabricated houses or temporary buildings mostly use metal steel plate roofs. In the sun, the indoor temperature will rise rapidly. In many cases, the effect of using air conditioning to cool down the indoor temperature is not good. Lowering indoor temperatures by lowering the roof surface temperature is usually the most practical way. The way to prevent the indoor temperature from rising is to make the outdoor heat (mainly the heat generated by sunlight) pass into the room as little as possible, and the indoor heat be dissipated as much as possible.
