example 1

[0021] According to the mass ratio of 1:6, polyethylene terephthalate and polymethyl silicone resin were mixed and stirred at 150°C for 8 minutes to obtain a modified silicone resin, and then the mass ratio was 2:5:7:1. Perfluoropolyether, polyester modified silicone resin, bisphenol A type epoxy resin and zinc powder were mixed and stirred at 30°C for 12 minutes, and the mixture was obtained after stirring, and biogas slurry with a mass of 0.5% of the mixture was continuously added to the mixture, and the Put it into a fermenter, seal and ferment for 5 days at a temperature of 30°C. After the fermentation is over, take out the fermentation product, which is a self-made modified bisphenol A epoxy resin, and mix acetic acid with a mass ratio of 1:2:1 Ethyl ester, methyl isobutyl ketone, and toluene were mixed and stirred for 30 minutes to obtain a self-made mixed solvent. Continue to weigh 30 g of quartz sand and grind it for 8 minutes. After grinding, quartz sand powder was obt...

Abstract

The invention relates to the technical field of conductive coatings and in particular relates to a method for preparing a wear-resistant anticorrosive conductive coating. The method comprises the following steps: mixing perfluoroalkylpolyether, a modified organic silicone resin, bisphenol A epoxy resin and zinc powder, blending with biogas slurry to ferment, decomposing the modified organic silicone resin to produce hydroxyl, amino and alkoxy by utilizing microbes, introducing the hydroxyl, amino and alkoxy onto the surface of the epoxy resin under the self-crosslinking action of the microbes, and generating a block polymer, so that the finally prepared conductive coating has excellent wear resistance; adding a mixed solvent of ethyl acetate, methyl isobutyl ketone and methylbenzene as well as quartz sand powder, so that the anticorrosive property and wear resistance of the conductive coating is improved; and adding a certain amount of conductive zinc powder, copper powder, talcum powder and strontium chromate, so that the wear resistance and corrosion inhibition capacity of the conductive coating are further improved. The conductive coating has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of conductive coatings, in particular to a preparation method of a wear-resistant and anti-corrosion conductive coating. Background technique [0002] Conductive coating is a kind of conductive filler and additives evenly dispersed in the resin to form a polymer material with a certain conductivity. Applying it to the surface of a high resistivity material can make the material have the ability to conduct current and eliminate the accumulation of static charge Therefore, in addition to the basic functions of ordinary coatings such as surface protection, aesthetics, and identification, conductive coatings also have the properties of some conductors. Conductive coatings are highly respected in the industry because of their good electrical conductivity, mechanical properties, and simplicity, and are widely used in many technical fields such as chemical industry, printing, electronics, electrical appliances, aer...
