Antirust agent for coating

Abstract

The invention relates to an antirust agent for a coating, which is characterized by containing the following components in parts by weight: 5-20 parts of citric acid, 5-30 parts of sodium silicate, 4-16 parts of ammonium nitrate, 10-20 parts of silicon dioxide particles, 10-20 parts of tri-n-butylamine, 5-25 parts of nitrilo-triethanolamine, and 10-50 parts of water. The antirust agent for a coating, prepared according to the invention, has excellent antirust property.

Description

technical field [0001] The invention relates to a rust inhibitor for coatings. Background technique [0002] In salty environments such as seawater or high temperature / humidity environments, white rust stains will form on the surface of metal-plated steel, resulting in a significantly deteriorated appearance of the substrate surface or a reduction in rust resistance. [0003] Therefore, developing a kind of antirust agent more and more receives people's attention. Contents of the invention [0004] The present invention proposes a kind of antirust agent for coating to above-mentioned problem. [0005] The specific technical scheme is as follows: [0006] A kind of antirust agent for coating, it is characterized in that, composition is as follows in parts by weight: [0007] 5-20 parts of citric acid, 5-30 parts of sodium silicate, 4-16 parts of ammonium nitrate, 10-20 parts of silica particles, 10-20 parts of tri-n-butylamine, 5-25 parts of nitrilo triethanolamine, 10-...
