Anti-aging composite waterproof coating material

Abstract

The present invention discloses an anti-aging composite waterproof coating material, which is prepared from the following raw materials by weight: 3.5-7.5 parts of an oligoester polyol, 1.5-2.8 parts of carboxy cellulose, 2.5-5.6 parts of a polycarboxylate type dispersant, 5-10 parts of ethylene glycol, 3.5-4.9 parts of amyl acetate, 1.5-2.8 parts of alkyl phenol polyoxyethylene ether polyoxypropylene ether, 1.2-2.4 parts of a castor oil ethylene oxide adduct and a derivative thereof, and 2.3-2.8 parts of dibutylnaphthalene sodium sulfonate. Compared with the existing waterproofing coating material, the anti-aging composite waterproof coating material of the present invention has characteristics of excellent high temperature resistance, excellent low temperature resistance and excellent sudden cold and heat change resistance, is suitable for polymer waterproof coating materials in the building industry, has good ductility and elongation at break in a wide temperature range, further has characteristics of strong adhesion, corrosion resistance, aging resistance, safety and environmental protection, and is suitable for coating on the surface of a variety of substrates.

Description

technical field [0001] The invention relates to an anti-aging 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 applicatio...
