Preparation method of elastic waterproof paint for color steel tile

Abstract

The invention discloses a preparation method of elastic waterproof paint for a color steel tile. The method comprises the following steps of (1) dissolving natural rubber into methylbenzene; then, continuously adding isopropoxyboronic acid pinacol ester and quadrol sodium allylsulfonate into the methylbenzene; performing uniform mixing and stirring to obtain elastic emulsion; (2) uniformly mixingmethyl pure silicon resin emulsion, dimethoxymethylvinylsilane, tetrapropyl orthosilicate and deionized water; performing heating and heat insulation treatment to obtain a substrate emulsion; (3) uniformly mixing the substrate emulsion, elastic emulsion, micro silicon powder, coalescing agents and polyethyleneimine to prepare the elastic waterproof paint for the color steel tile. The prepared elastic waterproof paint for the color steel tile has the advantages that green and environment-friendly effects are achieved; the volatile substance content is low; the drying speed is high; after the drying, the formed paint film has excellent absorption power and elasticity; when the color steel tile generates heat expansion and cold shrinkage to deform, the film layer cannot generate a cracking phenomenon; the protection can be effectively provided for the color steel tile for a long time.

Description

technical field

[0001] The invention belongs to the technical field of waterproofing of color steel tiles, and in particular relates to a preparation method of an elastic waterproof coating for color steel tiles. Background technique

[0002] With the continuous updating of technology, more and more materials with superior performance are applied to all aspects of our lives, especially the updating of building materials, which provides everyone with more superior living conditions. Color steel tile building materials have been recognized by everyone. Color steel tile is currently the most widely used color steel tile building material. It is widely used in factory building construction and temporary accommodation due to its advantages of beauty, light weight and low price. In particular, it has the advantages of strong earthquake resistance and waterproof, and has been widely promoted. However, color steel tiles also suffer from thermal expansion and cold contraction.
