Problems solved by technology

[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 inhalation, and there is still room for improvement

Abstract

The invention relates to the technical field of coatings. Aiming at the problem that silver powder paint is easy to emit harmful gas, a silver powder paint is provided, which is composed of component A and component B, and the mass ratio of component A to component B is 7.5‑8.5:1 ; Component A includes the following components in parts 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 activated carbon; silane coupling 7.5-10 parts of agent; 7.5-10 parts of polysiloxane, polysiloxane is a linear polymer chain, and the terminal groups at both ends of polysiloxane are hydroxyl and hydrogen respectively; component B includes polyurethane curing agent and n-butyl Alcohol, the mass ratio of polyurethane curing agent to n-butanol is 1:1. By adding activated carbon, the toxic gas with special smell volatilized by xylene is easily absorbed by the activated carbon, so that the silver powder paint is not easy to emit harmful gas, which is beneficial to improve the environmental protection performance of the silver powder paint.

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...
