Non-cracking heat insulation waterproof styrene-butadiene rubber coating and preparation method for same

Abstract

The invention discloses a non-cracking heat insulation waterproof styrene-butadiene rubber coating, which is prepared from the following raw materials in parts by weight: 100 parts of styrene-butadiene rubber emulsion, 8 to 10 parts of chloroprene rubber emulsion, 15 to 20 parts of hydroxyethyl methacrylate, 8 to 10 parts of alkyl resorcinol formaldehyde resin, 1 to 2 parts of hexakis methoxymethyl melamine, 3 to 5 parts of montmorillonite, 3 to 5 parts of zinc oxide, 1 to 2 parts of tricaprylyl citrate, 2 to 3 parts of tributyl phosphate, 1 to 2 parts of colophane, 2 to 3 parts of N-ethyl-N'-benzene diamine, 1 to 2 parts of hydroxymethyl cellulose, 8 to 10 parts of hollow glass beads and a proper amount of de-ionized water. The heat insulation waterproof material is low in construction cost and convenient to construct, and has good heat insulation effects, daylighting performance and broad 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 non-cracking 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. [0003] The thermal ...

Problems solved by technology

Now this kind of coating is undergoing a transformation from industrial heat insulation to building heat insulation. Low and decorative properties need to be further improved, etc., which limit the scope of application of this type of coating
