Abstract

The invention relates to anti-ageing composite paint which is characterized by comprising the following components in parts by weight: 40-60 parts of epoxy resin, 20-40 parts of styrene-acrylic emulsion, 6-12 parts of p-toluenesulfonic acid, 15-25 parts of sebacic dihydrazide, 2-8 parts of elm bark fiber, 30-50 parts of polyurethane, 8-15 parts of polyethylene micropowder wax, 1-5 parts of poly(butyl acrylate), 1-5 parts of dispersing agent, 1-5 parts of defoaming agent, 50-70 parts of titanium dioxide, 30-40 parts of iron oxide, 80-120 parts of zinc oxide powder, 10-20 parts of nano aluminum oxide and 5-10 parts of high-color carbon black. The paint provided by the invention is high in hardness and strength, and favorable in wear resistance, weather resistance and ageing resistance; a coated film is tough, resistant to acid and alkali and high in flexibility; the paint improves the dispersivity and flowability of the mixture system, has favorable compatibility with epoxy resin, is short in fusing time after mixing, and can also reduce the density of powdered paint; and the paint improves the painting rate, increases the coating area and lowers the production cost.

Description

technical field [0001] The invention relates to an anti-aging composite paint. Background technique [0002] The cracking and leakage of buildings and various structures is almost a common quality problem of today's concrete structures, and it is also a difficult problem that people continue to explore and study. It is hoped to provide a high-strength, high-elasticity, high-adhesion, anti-corrosion Impact, puncture-resistant, aging-resistant, corrosion-resistant, wear-resistant waterproof protective film. The existing waterproof materials have poor gloss and color retention, are not resistant to aging, are prone to yellowing, and have poor waterproof effects. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a technical solution for an anti-aging composite coating. [0004] The anti-aging composite coating is characterized in that it includes the following components in parts by weight: ...
