Problems solved by technology

However, the solid content of silicone resin material is generally 30%, which is low in solid content, and the viscosity of silicone resin is relatively high. Generally, it needs to be diluted with a solvent at 1:1 (solid content 15%) and added with a platinum catalyst for stirring before coating and drying. , the breakdown

Example Embodiment

[0010] Example 1

[0011] The composite glass fiber sleeve is made of methyl vinyl silicone rubber: solvent: hydrogen-containing silicone oil: platinum catalyst in a mass ratio of 2.8:16:0.009:0.001.

[0012] In the above embodiment, the production steps of the composite glass fiber sleeve are as follows: cut the methyl vinyl silicone rubber into small pieces, use a grinder to grind and extrude the massive methyl vinyl silicone rubber to the thickness of paper. Put the latter methyl vinyl silicone rubber into a solvent, dissolve and stir for 28 minutes, then add hydrogen-containing silicone oil and platinum catalyst, and stir for 20 minutes.

Abstract

The invention discloses a composite glass fiber casing and a production technology thereof. The composite glass fiber casing is prepared from methyl-vinyl silicone rubber, a solvent, hydrogen-containing silicone oil and a platinum catalyst. Methyl-vinyl silicone rubber is cut into small blocks and ground and extruded by a grinding machine into slices with paper thickness, the slices are placed into the solvent for dissolution stirring, the hydrogen-containing silicone oil is added and stirred, the platinum catalyst is added for stirring finally, and a product is obtained. The composite glass fiber casing has the advantages of high insulativity, heat resistance, high-temperature stability, flame retardance, hydrolysis resistance and oil resistance, good cold resistance, heat resistance and electric insulativity and low cost.

Description

technical field [0001] The invention relates to the field of materials, in particular to a composite glass fiber casing and a production process thereof. Background technique [0002] At present, the existing glass fiber sleeve material is prepared by silicone resin, solvent, and platinum catalyst at a mass ratio of 1:1:0.02, but the advantage of this material is that the material will form a highly crosslinked after thermal curing. Continuous network film with high insulation, heat resistance, high temperature stability, flame retardancy, hydrolysis resistance and oil resistance. However, the solid content of silicone resin material is generally 30%, which is low in solid content, and the viscosity of silicone resin is relatively high. Generally, it needs to be diluted with a solvent at 1:1 (solid content 15%) and added with a platinum catalyst for stirring before coating and drying. , the breakdown voltage of the finished product is about 1.5kv, and multiple coatings are ...
