Abstract

Disclosed is a rust-inhibiting priming paint, wherein the proportion of the raw material comprises (by weight percent) medium oil-degree dry oil alkide resin 25-35%, petroleum resin 5.5-7.5%, color filling material 45-55%, organic solvent 6-10% and auxiliary agent 2-3.5%.

Description

technical field [0001] The invention relates to antirust primer products of chemical coatings, in particular to a petroleum resin modified high-solid alkyd antirust primer, which is a commonly used primer for steel components. Background technique [0002] The anticorrosion of metal is a major engineering subject that affects the sustainable development of the national economy. The annual economic loss caused by corrosion in my country is as high as 280 billion yuan, exceeding the sum of all natural disaster losses. At present, the main anti-corrosion method for metals is to use anti-corrosion coatings. In my country, in addition to the use of new heavy-duty anti-corrosion coatings in large-scale steel structure engineering and the manufacture of movable steel components, alkyd and phenolic anti-rust primers are commonly used in the anti-corrosion coating and maintenance of general steel components, especially alkyd anti-rust primers. Acid red lead antirust primer and pheno...
