Rust-proof pigment

Abstract

The invention discloses a rust-proof pigment. The rust-proof pigment comprises the following raw materials in parts by weight: 30-50 parts of scale-shaped zinc powder, 2-10 parts of modified aluminum tripolyphosphate, 15-20 parts of titanium dioxide powder, 30-35 parts of zinc phosphate, 1-2 parts of calcium phosphate, 8-10 parts of calcium carbonate, 2-7 parts of a pigment dispersing agent, 2-5 parts of a silicane coupling agent, 3-7 parts of ammonium molybdate, 1-2 parts of coconut fatty acid diethanol amide, 10-15 parts of a dinonylnaphthalene sulfonic acid, 5-10 parts of ethyl orthosilicate, 0.5-0.9 part of a polyaspartic acid and 0.5-0.7 part of petroleum sodium sulfonate, and further comprises 1.5-3.2 parts of sepiolite powder. The rust-proof pigment disclosed by the invention is low in production cost; environmental pollution is avoided, that is, an environmental protection function is achieved; the rust-proof pigment is high in storage stability and cost performance, and has a certain of rust-proof and comprehensive performance.

Description

technical field [0001] The invention relates to pigments, in particular to an antirust pigment. Background technique [0002] The loss caused by metal corrosion is becoming more and more serious with the development of industry. The economic loss caused by metal corrosion accounts for about 5% of GDP in my country every year. Therefore, metal corrosion protection is very important. Although there are many anti-corrosion measures at present, they are the most widely used. The most economical and convenient method is still the paint protection method. In traditional antirust pigments, such as red lead, yellow lead, zinc chromate, strontium chromate, lead silicon chromate, high lead calcium, lead powder, etc., generally contain Elements such as lead, chromium and cadmium, although excellent in anti-rust performance, are poisonous, pollute the environment and endanger health. Therefore, the development and production of non-toxic, efficient and environmentally friendly anti-c...
