Flame-retardant waterproof coating for interior wall of building and preparation method thereof

Abstract

The invention discloses a flame-retardant waterproof coating for an interior wall of a building. The flame-retardant waterproof coating is characterized by being prepared from the following raw materials in parts by weight: 20-45 parts of organic silicon rubber emulsion, 5-8 parts of an organic silicon waterproof agent, 3-6 parts of graphene prefabricated dispersion, 0.1-0.6 part of emulsion type defoaming agent, 0.1-0.6 part of sodium carboxymethylcellulose, 2-4 parts of ammonium polyphosphate, 3-5 parts of magnesium hydroxide, 4-6 parts of C5 resin emulsion, 5-8 parts of calcined kaolin, 1-2 parts of dicumyl peroxide, 6-9 parts of tourmaline powder, and 1-2 parts of glycidyl methacrylate. The flame-retardant waterproof coating disclosed by the invention has unique water resistance, high elasticity and integrality; coating is continuously carried out without any seam; the flame-retardant waterproof coating is leakage-resistant; the binding property to various substrates of buildings is good; by means of the added graphene, the water resistance, anti-ultraviolet capability and anti-corrosion property of the coating are improved; and the coating disclosed by the invention also has good flame-retardant property, and has the advantages of being poisonless, tasteless, environmentally friendly, good in decoration, high in covering power, convenient to coat and wide in application range when used as an interior wall coating.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a flame-retardant waterproof coating used for interior walls of houses and a preparation method thereof. Background technique [0002] The coatings used in construction are mainly divided into waterproof coatings and anti-corrosion coatings, which have the functions of waterproof, anti-seepage and anti-corrosion respectively. In practical applications, the coating layer is often required to have waterproof and anti-corrosion functions at the same time, because the building is under harsh natural conditions, which will cause erosion and damage to the surface, which will seriously affect the quality of the building over time. However, existing coatings do not have waterproof and anti-corrosion properties at the same time, and some of them have short service life and unsatisfactory effects. Graphene is a new material with a single-layer sheet structure composed of carbo...

In practical applications, the coating layer is often required to have waterproof and anti-corrosion functions at the same time, because the building is under harsh natural conditions, which will cause erosion and damage to the surface, which will seriously affect the quality of the building over time.

However, the existing coatings do not have waterproof and anti-corrosion properties at the same time, and some of them have short service life and unsatisfactory effects.
