Embodiment

[0033] The anti-sticking material is 239 silicone grease, and its diluent is 120# industrial gasoline.

[0034] First, at room temperature, slowly pour 120# industrial gasoline into a container containing anti-sticking materials, and stir while pouring until it is evenly diluted and completely diluted.

[0035] An anti-adhesive paint coating process for electrical lead wires, the process steps are as follows:

[0036] A. Anti-adhesive treatment of metal filaments

[0037] The weight ratio of anti-sticking material to industrial gasoline is 1:6.

[0038] During the unwinding process before the metal filament bundle, the metal filament 1 is continuously passed through the container filled with the anti-stick coating prepared above, so that the anti-stick coating is evenly coated on the outer layer of each metal filament, and then the It passes through a hot air device continuously, and the temperature of the hot air is controlled at 180-200°C. The anti-adhesive material coated...

Abstract

The present invention discloses an anti-sticking coating used for an motor and electric appliance connection wire and its coating process, the anti-sticking coating comprises one or more of 106 silicone rubber, 107 silicone rubber, 239 silicone grease, 239-3 silicone grease and 201-100 methyl silicone oil, and a diluent is 120# industrial gasoline. The present invention is characterized by using industrial gasoline to replace diluents such as toluene, xylene and styrene which are commonly used in industry, and the toxicity to environment and the human body can be greatly reduced. The coating process of the present invention possesses good control of uniformity and thickness of an anti-sticking protective film which possesses effects for preventing the contact of paint liquid, metal filaments and an insulating sleeve contact during the impregnation process, and inhibiting the hardened metal filaments due to bonding, and bonding, swelling, sticky, fracturing, damage phenomena of the insulating sleeve.

Description

technical field [0001] The invention relates to an anti-adhesive coating, in particular to an anti-adhesive coating used for lead wires of electric motors and its coating process. Background technique [0002] The lead wires of motors and appliances need to withstand all the current and voltage of the motors and appliances. If the insulation of the leads is damaged or the performance is degraded, it will cause the failure or failure of the entire motor and appliances. [0003] In order to improve the insulation performance of electrical windings of motors, it is usually necessary to impregnate and bake the windings under various process conditions (immersion, vacuum pressure impregnation, etc.). Due to the needs of the process, the lead wires are often impregnated and baked together with the windings. deal with. During the varnish baking process, the varnish will adversely affect the lead wires, resulting in changes in the flexibility, insulation performance, and conductor ...
