Embodiment 1

[0010] An insulating primer, comprising the following components by weight: 30 parts of epoxy resin E-51, 15 parts of E-42, 13 parts of dimethylaminopropane, 3 parts of polyimide resin, 3 parts of zinc borate , 6 parts of magnesium carbonate, 2 parts of talcum powder, 1 part of barium metasulfate, 5 parts of lecithin, 2 parts of calcium epoxy acid, 0.5 parts of lead naphthenate, 5 parts of trimethylolpropane, 8 parts of benzoyl peroxide part, 0.5 part of xylidine, and 20 parts of solvent ethylene glycol.

[0011] The coating formed by the primer has a wear resistance of 20 times (load 200g), an insulation breakdown voltage of 12~13V, and a heat resistance temperature of above 90°C.

Embodiment 2

[0013] An insulating primer, comprising the following components by weight: 30 parts of epoxy resin E-20, 16 parts of dimethylaminopropane, 5 parts of polyimide resin, 1 part of zinc borate, 2 parts of magnesium carbonate , 6 parts of talcum powder, 3 parts of barium metasulfate, 3 parts of lecithin, 3 parts of calcium epoxy acid, 1.5 parts of lead naphthenate, 5 parts of trimethylolpropane, 5 parts of benzoyl peroxide, xylidine 1.5 parts, solvent xylene 25 parts.

[0014] The coating formed by the primer has a wear resistance of 20 times (load 200g), an insulation breakdown voltage of 14-15V, and a heat-resistant temperature of above 90°C.

Abstract

The invention provides an insulation primer which comprises, by weight, 30 to 45 parts of an epoxy resin, 13 to 16 parts of dimethylaminopropane, 3 to 5 parts of a polyimide resin, 1 to 3 parts of zinc borate, 2 to 6 parts of magnesium carbonate, 2 to 6 parts of talcum powder, 1 to 3 parts of barium metasulfate, 3 to 5 parts of phosphatidylcholine, 2 to 3 parts of epoxidized calcium, 0.5 to 1.5 parts of lead naphthenate, 5 to 12 parts of trimethylol propane, 5 to 8 parts of benzoyl peroxide, 0.5 to 1.5 parts of dimethyl aniline and 20 to 25 parts of a solvent, wherein the solvent is glycol or xylene, and the epoxy resin is one or a mixture of more selected from the group consisting of the epoxy resin E-20, the epoxy resin E-42 and the epoxy resin E-51. According to the invention, a proper amount of a resistance adjusting agent dimethylaminopropane is added into a formula for the insulation primer, so a resistance value of a film formed by the primer is increased, conductive capability is reduced, and an insulation effect is obtained.

Description

technical field [0001] The invention relates to an insulating primer, which belongs to the technical field of building materials. Background technique [0002] The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat and make the paint system play its best good effect. At present, with the improvement of people's living standards, in addition to the traditional requirements for the function of paint, it is also hoped that paint can bring some more practical functions, such as insulation, while exerting an aesthetic effect. Nowadays, there are more and more types of home appliances. People’s lives are inseparable from all kinds of electrical appliances that bring us convenience. Electrical leakage is also a common occurrence. Once a leakage accident ...
