8-Hydroxyquinoline conductive particle-grafted water-based fluorocarbon coating used for automobile chassis, and preparation method thereof

Abstract

The invention discloses a 8-hydroxyquinoline conductive particle-grafted water-based fluorocarbon coating used for automobile chassis, and a preparation method thereof. Above fluorocarbon resin has certain conduction property, and effectively alleviates electrochemical corrosion of the surface of a chassis metal material, introduced 8-hydroxyquinoline groups make the resin have a certain chelating adsorption effect on metal ion oil to realize corrosion inhibition, and an antirust pigment ground with a hyperbranched polyether emulsion has good dispersity and combination property in the resin system, so the finally prepared antirust coating has a good film forming effect, allows obtained films to be firm and compact, and has longer protection period and better application prospect than traditional aqueous antirust coatings.

Description

technical field [0001] The invention relates to the technical field of water-based antirust coatings, in particular to a water-based fluorocarbon coating grafted with 8-hydroxyquinoline conductive particles for automobile chassis and a preparation method thereof. Background technique [0002] As the name suggests, the chassis of the car is at the bottom of the car. It has been in a relatively dark environment, and it will be impacted by rain, sand and stones during driving, which will cause damage to the surface, accelerate corrosion, and seriously reduce the service life of the chassis. Therefore, strengthening the car The rust protection of the chassis is very important. [0003] The most direct and effective antirust measure for the chassis is to spray antirust paint on the chassis. The traditional antirust paint for the chassis is mainly oil-based paint. The advantage of oil-based paint is that it forms a thicker coating and has a longer service life, but its fatal The ...
