Abstract

The invention discloses a coating and conductive resin of a film zinc coat, which is prepared by the following steps of: weighing an organic solvent, methyl methacrylate, hydroxybutyl acrylate, hydroxyethyl methylacrylate, hydroxyethyl methacrylate phosphate, tert-butyl peroxy-2-ethylhexanoate and graphene oxide; adding 3/4 of the organic solvent and the graphene oxide into a reaction kettle A and mixing uniformly; uniformly mixing the methyl methacrylate, hydroxybutyl acrylate, hydroxyethyl methylacrylate, hydroxyethyl methacrylate phosphate and 3/4 of the tert-butyl peroxy-2-ethylhexanoate, dropwise adding the mixture into a dropwise adding tank B, and then dropwise adding into the reaction kettle A; uniformly mixing the residual organic solvent and tert-butyl peroxy-2-ethylhexanoate, dropwise adding the mixture into the dropwise adding tank B, then dropwise adding into the reaction kettle A at 113-118 DEG C, preserving heat for 0.8-1.2 hours, cooling and filtering; and performing ultrasonic treatment, adding hydrazine hydrate for reaction, filtering, washing and drying. The prepared film zinc coat has better corrosion resistance.

Description

technical field [0001] The invention relates to a coating and galvanized resin, in particular to a one-component acrylate modified graphene coating and conductive resin. Background technique [0002] Coated galvanized products (also known as zinc-based coating or cold galvanized products on the market), with its new, long-term, environmentally friendly and convenient steel structure anti-corrosion technology, especially in steel structure maintenance, show outstanding advantages. It not only inherits the advantages of traditional electrogalvanizing, thermal spraying zinc and zinc-rich coatings, but also overcomes their shortcomings. The dry film metal zinc content can be as high as 96%, and it has dual protection functions of cathodic protection and barrier protection, and has good application prospect. [0003] However, due to the defects in the selection of resin and resin-coated zinc powder technology in the existing coated galvanized products, the electrical conductivit...
