Abstract

The invention provides waterproof paint for decoration and a preparation method of the waterproof paint. The waterproof paint is prepared from the following components: epoxy resin, butyl p-hydroxybenzoate, carboxy methyl cellulose, white emulsion, ethylenediamine, nano silicon dioxide, talcum powder, castor oil, polyether glycol, modified starch, diluting agent, polyurethane film forming agent, binder and water. The prepared waterproof paint has the characteristics of adaptability to the deformation of a base layer, and high binding strength, is difficult to separate from the base layer, excellent in ultraviolet aging resistance and low-temperature resistance, also has the characteristics of high weather resistance, water resistance and high contamination resistance, and is simple in preparation method, free from needing special preparation tool, wide in source of raw materials, low in cost, nontoxic, pollution-free, and suitable for mass popularization and production.

Description

technical field [0001] The invention belongs to the technical field of decorative materials, and in particular relates to a waterproof paint for decoration and a preparation method thereof. Background technique [0002] Waterproof paint is mainly used in buildings, and it has two functions: one is to protect the building from the external environment or minimize the impact: after the waterproof paint and its preparation method are applied to the building, it can form a continuous layer on the surface. Paint film, this paint film has corrosion resistance, pollution resistance, ultraviolet radiation resistance, and bacterial erosion resistance, which can protect steel bars from corrosion and concrete from carbonization and hydrogenation, so as to prolong the life of buildings; the second is to decorate and beautify buildings: waterproof The lacquer and its preparation method can form coating films with different colors, different lusters and different textures after being coat...
