Abstract

The invention discloses an anti-corrosive primer for an automobile chassis. The primer is prepared from, by weight, 23-25% of bisphenol F-type liquid epoxy resin, 5-8% of cellulose ether, 12-15% of aluminum powder, 10-12% of butyl acetate, 15-18% of multifunctional additive AMP-95, 12-15% of nano silica, 3-8% of polysulfone and the balance polyethylene glycol. The invention further provides a preparation method of the anti-corrosive primer for the automobile chassis. The primer is quick to dry, free of peculiar smell, stable to alkali and most solvents and long in service life and has anti-corrosive and gas and water blocking properties and good friction and high temperature resisting performance.

Description

technical field [0001] The invention relates to an automobile chassis, in particular to an anti-corrosion primer for the automobile chassis. Background technique [0002] At present, many automobile chassis need to be painted with primer after surface treatment, and its main function is to protect the automobile chassis from being corroded by the atmosphere and sewage. 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 this invention is to propose a kind of anticorrosion primer for automobile chassis, which has fast drying, no peculiar smell, stable ...
