Heat insulation waterproof paint of butadiene styrene rubber modified by nanometer SiO2 and preparation method thereof

Abstract

The invention relates to heat insulation waterproof paint of butadiene styrene rubber modified by nanometer SiO2. The paint is prepared from the following raw materials in parts by weight: 100 parts of butadiene styrene rubber emulsion, 8 to 10 parts of chloroprene rubber emulsion, 15 to 20 parts of hydroxyethyl methylacrylate, 8 to 10 parts of alkyl resorcinol formaldehyde resin, 1 to 2 parts of hexakis methoxymethyl melamine, 3 to 5 parts of titanium dioxide, 3 to 5 parts of talcum powder, 1 to 2 parts of sodium tripolyphosphate, 2 to 3 parts of tributyl phosphate, 1 to 2 parts of texanol, 0.5 to 1 part of 1,2-benzoisothiazolinone-3-ketone, 1 to 2 parts of hydroxymethyl cellulose, 8 to 10 parts of hollow glass micro beads, 3 to 4 parts of 25-percent ammonium hydroxide, 40 to 50 parts of absolute ethyl alcohol, 3 to 5 parts of ethyl orthosilicate, 5 to 8 parts of hydroxyl silicone oil, 1 to 2 parts of white carbon black, 0.5 to 1 part of dibutyltin dilaurate and a proper amount of deionized water. The paint has the advantages that the manufacturing price is low; good heat insulation effects and lighting degrees are realized; the construction is simple and convenient; the application prospects are good.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano-SiO 2 A modified styrene-butadiene rubber heat-insulating waterproof coating 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 therm...
