Abstract

The invention discloses a novel composite waterproof coating which is prepared by the following raw materials by weight: 3.5-7.5 parts of carboxycellulose, 1.5-2.8 parts of sodium polycarboxylate, 2.5-5.6 parts of toluene diisocyanate, 5-10 parts of glycol, 3.5-4.9 parts of amyl acetate, 1.5-2.8 parts of alkylphenol polyoxyethylene ether polyoxypropylene ether, 1.2-2.4 parts of castor oil ethylene oxide addition products and their derivatives, and 2.3-2.8 parts of sodium dibutylnaphthalenesulfonate. Compared with existing waterproof coatings, the coating of the invention has excellent high temperature resistance, low temperature resistance, and shock cooling and shock heating resistance, is a high-molecular waterproof coating suitable for use in building industry, has good ductility and elongation at break in a wide temperature range, is strong in bonding force, is corrosion resistant, aging resistant, safe, and environment-friendly, and is suitable for coating on various base material surfaces.

Description

technical field [0001] The invention relates to a novel composite waterproof paint, which belongs to the field of building materials. Background technique [0002] The waterproof coating used in the construction industry is generally a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it will form a waterproof film on the surface of the base layer after solvent volatilization or water evaporation or reaction curing. At present, the waterproof materials used in the construction industry are generally divided into flexible waterproof materials including waterproof membranes, waterproof coatings, sealing ointments, etc., and rigid waterproof materials based on cement substrates, adding waterproofing agents and other additives. Although there are many types, they generally have disadvantages such as poor physical and mechanical properties, short service life, too large gap with the service life of buildings, narrow application rang...
