Aluminum paint

Abstract

The invention relates to the technical field of coatings, and provides an aluminum paint to solve a problem that aluminum paints easily emit harmful gases. The aluminum paint is composed of a component A and a component B, and a mass ratio of the component A to the component B is (7.5-8.5):1; the component A comprises, by mass, 82.5-110 parts of polyurethane resin, 30-40 parts of metal powder, 9.9-13.2 parts of xylene, 6-8 parts of butanol, 1.5-2 parts of active carbon, 7.5-10 parts of a silane coupling agent and 7.5-10 parts of polysiloxane, the polysiloxane is a linear polymer chain, and endgroups at both ends of the polysiloxane are a hydroxyl group and hydrogen respectively; and the component B includes a polyurethane curing agent and n-butanol, and a mass ratio of the polyurethane curing agent to the n-butanol is 1:1. The addition of the active carbon makes the toxic gases, with special smell, volatilized from xylene easily absorbed by the active carbon, so the aluminum paint isnot prone to emit the harmful gases, and the improvement of the environmental protection performance of the aluminum paint is benefited.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, it relates to a silver powder paint. Background technique [0002] Silver powder paint is a kind of fluid that adds aluminum powder as a special pigment to the paint and stirs it with aluminum powder and thinner. It is mostly used for painting the surface of plumbing pipes in old-fashioned buildings. [0003] But the solvent of paint usually contains components such as benzene, toluene or xylene, and benzene, toluene, and xylene all have the special odor of aromatic hydrocarbons and are easy to volatilize, so that the paint is easy to emit odor. It has certain toxicity, and it is easy to cause harm to the human body after being inhaled by the human body, and there is still room for improvement. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a silver powder paint which has the advantages of en...
