Problems solved by technology

Among them, mosaic has good water resistance, but its cost is high and construction is difficult. However, the existing coatings with asphalt or coal tar are generally easy to construct, but the waterproof effect is not good enough. After several years of wind and sun, peeling occurs. and other phenomena, serious environmental pollution, great harm to human body and other problems

Abstract

The invention discloses an outer wall waterproof coating. The outer wall waterproof coating is prepared from the following raw materials in parts by weight: 25-35 parts of silicon acrylate emulsion, 25-40 parts of filler, 1-8 parts of film forming additive, 1-5 parts of dispersant, 0.1-0.5 parts of thickener, 0.5-2 parts of flow agent, 1-5 parts of defoamer and 30-40 parts of dedeionized water. The outer wall waterproof coating is strong in the permeability resistance, obvious in the waterproofness, good in weatherability, and strong in acid-resisting, alkali-resisting and corrosion-resisting capability, has stronger high temperature resistance, does not have chemical odor which is harmful to a human body, is simply prepared and is an ideal outer wall waterproof coating.

Description

technical field [0001] The invention relates to a building material, in particular to a waterproof coating for exterior walls. Background technique [0002] Architectural waterproof coating is a sticky silk-like liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough waterproof coating film on the surface of the base layer after the volatilization of solvent or water evaporation or reflection curing. , is currently widely used on the exterior walls or roofs of houses. The main reasons why people use waterproof coatings are: First, the buildings are exposed to sunlight and the temperature rises, especially in summer, which makes the room more stuffy; It will leak into the room from the outer wall or roof of the house, affecting people's work and life. At present, it is often treated with mosaic or paint, which mainly plays the role of decoration and waterproof. Among them, mosaic has good water resistance, but its cost ...
