Abstract

The invention discloses an environment-friendly waterproof building coating for a wall surface. The coating is prepared from the following raw materials in parts by weight: 55-70 parts of alkyd resin,35-50 parts of a single-component polyurethane adhesive, 15-20 parts of magnesium nitrate powder, 15-25 parts of aluminum nitrate powder, 38-52 parts of waterproof slurry, 15-28 parts of sodium carboxymethyl cellulose, 55-70 parts of absolute ethyl alcohol, 5-15 parts of a thickening agent and 3-8 parts of a cosolvent. The invention further discloses a preparation method of the environment-friendly waterproof building coating for the wall surface. In the preparation of the environment-friendly waterproof building coating for the wall surface, the single-component polyurethane adhesive, the waterproof slurry and other substances are added; the single-component polyurethane adhesive is not mixed with coal tar, petroleum resin, asphalt and an organic solvent, so that the environment-friendlyrequirement is met, the product quality stability and the waterproof effect of the prepared waterproof coating are ensured, and the waterproof slurry can endow the environment-friendly waterproof building coating for the wall surface with excellent waterproof and heat-insulating properties.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an environmentally friendly waterproof architectural coating for walls and a preparation method thereof. Background technique [0002] Architectural waterproof coating is a viscous 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 reaction curing. the general term for. Common types of waterproof coatings include polyurethane waterproof coatings, one-component polyurethane waterproof coatings, polymer cement waterproof coatings, polymer emulsion waterproof coatings, asphalt waterproof coatings and modified bitumen waterproof coatings. [0003] There are many ways to decorate and protect buildings, but the use of coatings is one of the simplest, most economical, and convenient for maintenance and renewal, ...
