[0024] Weigh tea leaves, red bayberry and fresh grapes according to the mass ratio of 1:1:2, wash them once with deionized water, put them into a tissue pulverizer, pulverize for 20 minutes to obtain a mixed pulverized product, mix the pulverized product, cellulase and fruit Glue enzyme is mixed according to the mass ratio of 10:1:1 and put into the enzymolysis tank, and the enzymolysis product is obtained at 28°C for 6 hours; then the enzymolysis product and glucose are mixed according to the mass ratio of 6:1. As a fermentation substrate, put the fermentation substrate into a fermenter, seal the mouth of the fermenter with plastic wrap, and seal and ferment at a temperature of 30°C for 10 days. After the fermentation is over, filter and separate to obtain the fermentation filtrate; calculated in parts by weight , weighed 30 parts of the above fermentation filtrate, 40 parts of fluorocarbon resin with a solid content of 55% and a fluorine content of 35%, 15 parts of sodium dih...

Abstract

The invention relates to the technical field of preparation of electronic component paint, in particular to a preparation method of a two-component high-adhesion pollution flashover-prevention fluorocarbon coating for a hard mask. The preparation method comprises the following steps: with waxberries, grapes and tea leaves as raw materials, degrading cellulose in the raw materials into glucose withcellulose and fermenting, and mixing a fermentation filtrate with fluorocarbon resin, water glass, magnesium oxide, monopotassium phosphate and the like to prepare the two-component fluorocarbon coating, wherein a proper amount of MgO powder is mixed in the water glass in a component A, then a layer of coating component B is coated, and phosphate in the component B is in an acid-base neutralization reaction with the MgO powder on the surface of an insulator. The fluorocarbon resin is taken as a film forming matter, so that the oxidation resistance of the coating is further improved; an organic acid composition and silicon dioxide generated by sodium carbonate in the component A improve the adhesion of a film; silicon dioxide is mixed to improve the hardness of the coating and the mechanical property of the film; and therefore, the two-component high-adhesion pollution flashover-prevention fluorocarbon coating has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of preparation of coatings for electronic components, in particular to a method for preparing a two-component high-adhesion hard film antifouling flash fluorocarbon coating. Background technique [0002] Pollution flashover refers to the phenomenon that the soluble substances of the dirt attached to the insulating surface of electrical equipment gradually dissolve in water under humid conditions, forming a conductive film on the insulating surface, which greatly reduces the insulation level of the insulator, and occurs under the action of an electric field. Strong discharge phenomenon. [0003] Under severe weather conditions (such as: fog, dew, drizzle, etc.), flashovers will occur along the wet insulator surface, resulting in power system pollution flashover accidents. Pollution flashover threatens the safe and stable operation of the power system. If it is mild, it will affect local power supply. If it i...
