Embodiment Construction

[0014] A double-sided silicone polyimide film with less rubber powder mica tape, including mica paper and polyimide film. The polyimide film is arranged on the upper and lower surfaces of the mica paper. The thickness of mica paper is 0.035-0.065mm, and the thickness of polyimide film is 0.03-0.035mm.

[0015] The mica paper and the polyimide film on the upper and lower surfaces are bonded together by glue. The rubber compound includes silicone resin, modifying additives, additives, toluene and ethyl acetate, and the weight ratio of silicone resin, modifying additives, additives, toluene and ethyl acetate is 10:0.6:0.24:18:12 . The weight per unit area of ​​the rubber in the mica tape is 3-9 g / ㎡.

[0016] The preparation method of the above-mentioned double-sided silicone polyimide film less rubber powder mica tape comprises the following steps:

[0017] (1) Mix and stir the silicone resin, modifying additives, additives, toluene, ethyl acetate and emulsifying dispersant, ...

Abstract

The invention relates to a cable fire-resistant insulation material, and particularly relates to a double-faced organic silicon polyimide film dry mica paper tape which comprises mica paper and polyimide films. The polyimide films are arranged on upper and lower surfaces of the mica paper. The mica paper and the polyimide films on upper and lower surfaces are bonded together through glue materials. Each glue material consists of organic silicon resin, a modified additive, an additive, toluene and ethyl acetate. The weight ratio of the organic silicon resin, the modified additive, the additive, the toluene to the ethyl acetate is 10:0.6:0.24:18:12. The glue material content in the mica tape is 3 to 9 g / square meter. The thickness of the mica paper is 0.035 to 0.065mm. The thickness of each polyimide film is 0.03 to 0.035mm. The preparation method of the double-faced organic silicon polyimide film dry mica paper tape has the steps of glue material configuring, dip coating, compositing, drying, cooling, rewinding and slitting. The product has the advantages of easy manufacture, good fire-resistant insulation performance, strong shock-resistant performance and low processing cost.

Description

technical field [0001] The invention relates to a fire-resistant insulating material for cables, in particular to a double-sided organosilicon polyimide film less rubber powder mica tape and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the market demand for cables is increasing day by day. The refractory insulating material commonly used in cable production is mica tape, and the quality of the refractory insulating material directly or indirectly affects the performance of the cable. Mica tape is a kind of main insulating material. Mica tape is divided into multi-adhesive mica tape and less-adhesive mica tape according to the adhesive content. Among them, multi-adhesive mica tape refers to mica tape with an adhesive content of more than 35%. Part of the motor insulation structure; adhesive-less mica tape refers to mica tape with a very low adhesive content, which becomes part of the motor insulation structure through...
