preparation example Construction

[0015] The present invention provides a kind of preparation method of insulating varnish, wherein, described preparation method comprises:

[0016] (1) Heating and stirring diphenyldichlorosilane, trichlorosilane, epoxy resin and organic solvent until completely dissolved to obtain a mixture M1;

[0017] (2) Add a curing agent and a film-forming agent to the mixture M1 and stir evenly to obtain an insulating varnish; wherein,

[0018] Relative to 100 parts by weight of diphenyldichlorosilane, the amount of trichlorosilane is 60-140 parts by weight, the amount of epoxy resin is 20-70 parts by weight, and the amount of organic solvent is 150- 230 parts by weight, the amount of the curing agent is 1-5 parts by weight, and the amount of the film-forming agent is 1-5 parts by weight.

[0019] The present invention uses diphenyldichlorosilane and trichlorosilane as the main raw materials, adds epoxy resin, dissolves it through an organic solvent, and adds a curing agent and a film-...

Embodiment 1

[0033] Heat and stir 100g of diphenyldichlorosilane, 80g of trichlorosilane, 40g of epoxy resin and 180g of toluene until completely dissolved to obtain a mixture M1; add 0.5g of polydimethylsiloxane, 0.5g of ethylene Bis stearamide, 2g of diethylenetriamine and 2g of acrylic resin were stirred evenly to obtain insulating varnish N1; silk was immersed in insulating varnish N1 and after the insulating varnish N1 attached to the silk was dried, yellow wax silk A1 was obtained.

Embodiment 2

[0035] Heat and stir 100g of diphenyldichlorosilane, 120g of trichlorosilane, 60g of epoxy resin, 100g of acetone and 110g of ethyl acetate until completely dissolved to obtain mixture M1; add 2g of alkyl-modified organosiloxane to mixture M1 alkane, 2g monoglyceride stearate, 4g m-xylylenediamine and 4g polybutadiene resin and stir evenly to obtain insulating varnish N1; the acrylic fiber is immersed in the insulating varnish N1 and the insulating varnish N1 attached to the acrylic fiber is dried Finally, yellow wax silk A2 is obtained.

Abstract

The invention discloses a preparation method of insulation varnish. The preparation method comprises the steps of heating diphenyl-dichlorosilane, trichlorosilane, epoxy resin and an organic solvent to obtain a mixture, and stirring until the mixture is completely dissolved to obtain a mixture M1; feeding a curing agent and a film-forming agent into the mixture M1, and evenly stirring to obtain the insulation varnish, wherein based on every 100 parts by weight of diphenyl-dichlorosilane, 60-140 parts by weight of trichlorosilane, 20-70 parts by weight of the epoxy resin, 150-230 parts by weight of the organic solvent, 1-5 parts by weight of the curing agent, and 1-5 parts by weight of the film-forming agent are added. The invention also discloses the insulation varnish, a yellow varnished silk and a preparation method of the yellow varnished silk. The diphenyl-dichlorosilane and the trichlorosilane are taken as main raw materials, the epoxy resin is fed into the raw materials, and the organic solvent is used for dissolving the materials, so that the yellow varnished silk which has the good service performances and is not easily adhered can be finally obtained.

Description

technical field [0001] The invention relates to the field of production and processing of insulating materials, in particular to an insulating varnish and a preparation method thereof, yellow wax silk and a preparation method thereof. Background technique [0002] Yellow wax silk is widely used in industrial production such as daily motors, and the quality of yellow wax silk directly determines the quality of the manufactured motor. Therefore, in the actual production process, the insulation performance and service performance of yellow wax silk often determine the performance of the motor. However, in the prior art, the yellow wax silk is often easy to stick, and the motor is prone to heat during use, which will cause the yellow wax silk to stick, and then bring certain troubles to the production. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a yellow wax silk that is not easy to stick and has good usability and its preparatio...
