Preparation method of high-adhesive-force ultraviolet-proof and anti-pollution flashover coating

Abstract

The invention relates to the technical field of preparation of electronic element coating and in particular relates to a preparation method of high-adhesive-force ultraviolet-proof and anti-pollutionflashover coating. The high-adhesive-force ultraviolet-proof and anti-pollution flashover coating is prepared by taking montmorillonite, titanium white powder and aloes as raw materials, fermenting toobtain a modified product, taking green alga as a raw material and finally mixing the modified product and modified vulcanized silicone rubber and reacting. According to the preparation method, the montmorillonite, the titanium white powder and the aloes are used as the raw materials firstly and the obtained modified product has extremely excellent ultraviolet-proof performance; an active group on a fermented product is introduced into the anti-pollution flashover coating, so that the quantity of the active groups of a coating matrix can be increased and the bonding strength between the coating and an electric equipment substrate is improved; and boron-silicon rubber is adopted so that the adsorption performance of the anti-pollution flashover coating on the electric equipment substrate is improved and the high-adhesive-force ultraviolet-proof and anti-pollution flashover 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 preparation method of a high-adhesion anti-ultraviolet and anti-pollution flashover 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 is seriou...

Problems solved by technology

[0007] The technical problem mainly solved by the present invention is that the adhesion between the current paint and the substrate surface of electrical equipment is low, and the anti-fouling flashover paint is prone to peeling and peeling during use. When exposed to the outdoors for a long time, it is affected by ultraviolet rays , the defect that its anti-fouling flashover life is not long, provides a kind of preparation method of anti-ultraviolet anti-fouling flashover coating with high adhesion
