Abstract

The invention provides a rust proof coating for machinery equipment and a preparation method thereof. The coating contains the following components by weight: 30-45 parts of coal tar, 8-14 parts of maleic anhydride, 3-6 parts of modified phenolic resin, 10-20 parts of barium borate, 8-15 parts of molybdenum dioxide, 7-14 parts of aluminum tripolyphosphate, 1-3 parts of diatomite, 1-3 parts of kaolin, 1-3 parts of light calcium carbonate, 4-8 parts of propylene glycol, 0.6-1.1 parts of lead naphthenate, and 15-30 parts of deionized water. The coating provided by the invention has excellent rust resistance and wear resistance, hardly peels or blisters, has little environmental pollution, and can effectively protect the mechanical equipment, and prolong the service life of mechanical equipment.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an antirust coating for mechanical equipment and a preparation method thereof. Background technique [0002] Mechanical equipment exists in all walks of life, brings many products and conveniences to people, and plays a very important role in people's lives. Mechanical equipment is generally made of metal, so anti-rust treatment is required. At the same time, mechanical equipment is prone to wear and tear during use. One of the current solutions to these problems is to apply paint. However, the antirust performance of the existing coatings for mechanical equipment is not high, and they are easy to wear. Contents of the invention [0003] Technical problem to be solved: Aiming at the disadvantages of low antirust performance and easy abrasion of existing coatings for mechanical equipment, the invention provides an antirust coating for mechanical equipment and a preparation method ther...
