Abstract
The invention discloses an electric-insulation siloxane varnish which comprises 280-320 parts of methylphenyl dichlorosilane, 80-120 parts of phenyl trichlorosilane, 200-260 parts of methyl trichlorosilane, 40-50 parts of diphenyl dichlorosilane, 500-600 parts of toluene, 400-500 parts of methylethylketone and 2000-2200 parts of water. Thus, the electric-insulation siloxane varnish has the advantages of excellent heat resistance, low tendency to melting at high temperature and high electric insulativity, and is mainly used for wire application.
Description
Technical field
The present invention relates to siloxane finish, particularly relate to a kind of siloxane finish of electrical isolation.
Background technology
Traditional siloxane finish is mainly used in the application of electric wire, but its resistance toheat is poor, runs into high temperature and easily melts, and can bring danger.
Summary of the invention
Object of the present invention provides a kind of siloxane finish of electrical isolation, solves one or more in above-mentioned prior art problem.
According to an aspect of the present invention, a kind of siloxane finish of electrical isolation is provided, comprise dichloromethyl phenylsilane 280-320 part, phenyl-trichloro-silicane 80-120 part, METHYL TRICHLORO SILANE 200-260 part, diphenyl dichlorosilane 40-50 part, toluene 500-600 part, methylethylketone 400-500 part, water 2000-2200 part.
During production, first in hot water bath, in 1h, dichloromethyl phenylsilane, phenyl-trichloro-silicane, METHYL TRICHLORO SILANE, diphenyl dichlorosilane and toluene are added in water and in methylethylketone, stir, temperature controls at 25 DEG C, stir that 1h is separated, washing organic phase to anacidity, distillation except desolventizing, at 200 DEG C of heating 5h, gained stickiness resin and equivalent dimethylbenzene and epoxy hydrochlorate are mixed and made into varnish.
The present invention has excellent resistance toheat, at high temperature not easily melts, and electrical insulating property is strong, is mainly used in the application of electric wire.
Embodiment
Embodiment 1: comprise dichloromethyl phenylsilane 280 parts, phenyl-trichloro-silicane 80 parts, METHYL TRICHLORO SILANE 200 parts, diphenyl dichlorosilane 40 parts, toluene 500 parts, methylethylketone 400 parts, 2000 parts, water.
Embodiment 2: comprise dichloromethyl phenylsilane 300 parts, phenyl-trichloro-silicane 100 parts, METHYL TRICHLORO SILANE 230 parts, diphenyl dichlorosilane 45 parts, toluene 550 parts, methylethylketone 450 parts, 2100 parts, water.
Embodiment 3: comprise dichloromethyl phenylsilane 320 parts, phenyl-trichloro-silicane 120 parts, METHYL TRICHLORO SILANE 260 parts, diphenyl dichlorosilane 50 parts, toluene 600 parts, methylethylketone 500 parts, 2200 parts, water.
During production, first in hot water bath, in 1h, dichloromethyl phenylsilane, phenyl-trichloro-silicane, METHYL TRICHLORO SILANE, diphenyl dichlorosilane and toluene are added in water and in methylethylketone, stir, temperature controls at 25 DEG C, stir that 1h is separated, washing organic phase to anacidity, distillation except desolventizing, at 200 DEG C of heating 5h, gained stickiness resin and equivalent dimethylbenzene and epoxy hydrochlorate are mixed and made into varnish.
In sum, the present invention has excellent resistance toheat, at high temperature not easily melts, and electrical insulating property is strong, is mainly used in the application of electric wire.
The above is only one embodiment of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, these also should be considered as within protection scope of the present invention.
