Problems solved by technology

Solvent-free high-strength polyurethane waterproof coatings and sprayed polyurea elastomers are new high-grade materials in the polyurethane waterproof coating family, but their synthesis and construction processes are relatively complicated, and the cost is relatively high. At present, they are only used in the waterproofing of high-speed railway bridges. application, it is difficult to be accepted by general users
That is to say, it is difficult for existing waterproof coatings to meet the comprehensive requirements of good mechanical properties, wide application range, convenient operation, price and environmental protection.

Abstract

The invention relates to a colourful environmental-friendly synthesized polymer waterproof paint which comprises the following components in parts by weight: 3-7 parts of petroleum resin, 5-15 parts of styrene-ethylene-butylene-styrene (SEBS), 5-15 parts of styrene-butylene-styrene (SBS), 5-10 parts of thermoplastic polyurethane elastomer, 4-8 parts of terpene resin, 4-8 parts of poly-alpha-methyl styrene, 2-5 parts of tung oil, 10-15 parts of mica powder, 0.2-0.5 part of antiager D, 0.2-0.5 part of antioxidant 264, 0.2-0.5 part of defoaming agent, 0.3-0.5 part of ultraviolet absorber, 35-45 parts of 120 # solvent, 5-15 parts of butyl acetate and 1-3 parts of color paste. The paint has the characteristics of unique waterproof property, acid-base resistance, ultraviolet irradiation resistance, heat insulation, anti-aging property, high adhesion strength, water repellent, good leakage-resisting effect, heat resistance, frost resistance and good elongation; and the paint also has the advantages of wide application range, moderate price, environmental friendliness, durability and the like, and is convenient to use, thereby meeting the demand of people in a real life.

Description

Technical field: [0001] The invention relates to a building waterproof material, in particular to a colorful and environment-friendly synthetic polymer waterproof paint. technical background: [0002] At present, there are many kinds of waterproof coatings, but most of them have poor physical and mechanical properties, short service life, and the gap between the service life of buildings is too large, the application range is narrow, and they are not necessarily environmentally friendly. Polyurethane waterproof coating is a relatively high-grade waterproof coating in the current waterproof coating, and its comprehensive performance is obviously better than other waterproof coatings. ) have environmental protection problems, and their mechanical properties are still insufficient. Solvent-free high-strength polyurethane waterproof coatings and sprayed polyurea elastomers are new high-grade materials in the polyurethane waterproof coating family, but their synthesis and constr...
