Abstract

The invention discloses permeating and curing inorganic mineral color dry powder paint for a highway bridge. The permeating and curing inorganic mineral color dry powder paint is prepared from, by weight, 20-40 parts of Portland cement, 15-25 parts of vinyl acetate copolymer, 15-25 parts of styrol copolymer, 8-12 parts of organosilicon compound, 10-20 parts of inorganic filler, 2-6 parts of coupling agent, 1-3 parts of curing agent, 2-6 parts of fortifier, 1-3 parts of inorganic adhesive, 1-3 parts of antibacterial agent, 4-8 parts of mineral colored stone and 3-5 parts of pigment. The permeating and curing inorganic mineral color dry powder paint for the highway bridge has good anti-leakage, antibacterial and anti-mold effects, is good in weather resistance, acid and alkali resistance and flame retardant effect, free of toxicity and smell, and releases no harmful substances; the preparing method is simple and low in preparing cost, and the color dry powder paint can effectively avoid alkali efflorescence and desquamation problems, prolongs the service life of the highway bridge when used in the highway bridge and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a permeation-curing inorganic mineral color dry powder coating for highway bridges. Background technique [0002] The environmental pollution caused by the waste water, sludge, waste and waste residue discharged by the paint industry every year cannot be underestimated. In particular, a large amount of organic volatile compounds emitted during the production and use of coatings has attracted great attention from relevant state departments and the general public, and the advantages of environmentally friendly powder coatings have gradually emerged. Color dry powder coating is formulated with inorganic gelling materials and redispersible polymer resin powder as film-forming aids, adding composite inorganic fillers and pigments. It is a new cement-based modern building decoration material combining inorganic and organic. Dry powder coatings are compounded with common substances an...
