Abstract

The invention discloses a quick-drying high-temperature-resistant undercoat for steel. The undercoat comprises the following component in percentage by weight: 26-28% of bisphenol F-type liquid epoxy resin, 6.5-6.8% of iron oxide red powder, 11-13% of titanium dioxide, 8-10% of a defoamer, 5.5-5.8% of a fire retardant, 3.2-3.8% of mica, 8-12% of a multifunctional additive AMP-95, 12.2-12.5% of graphite powder, and the balance of watercraft acrylic resin. According to the preparation method for the quick-drying high-temperature-resistant undercoat used for the steel, the undercoat is dried quickly, has no peculiar smell, and is good in adhesive property, stable to alkaline and most solvents, good in corrosion resistance, gas resistance, inflaming retarding, water resistance, thermal insulation and the like , and excellent in friction resistance and high temperature resistance.

Description

technical field [0001] The invention relates to a primer and a preparation method thereof, in particular to a quick-drying high-temperature resistant primer for steel and a preparation method thereof. Background technique [0002] At present, many mechanical surface treatments need to be painted with primer, and its main function is to protect the steel from atmospheric corrosion during processing. There are many types of primers on the market, but they generally have the defects of slow drying, poor corrosion resistance, and poor high temperature resistance, which not only reduces the service life of the equipment, increases costs, but also leads to low work efficiency due to long drying time, and During the processing, it is easy to emit chemical odor, which is harmful to the health of operators. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a quick-drying high-temperature-resistant primer for steel and a pr...
