Abstract

The invention discloses a preparation method of a silicone rubber glass fiber hose, comprising the following steps: S1, selecting a silicone rubber sleeve obtained by extrusion, and weaving alkali-free glass fibers outside the silicone rubber sleeve to form an alkali-free glass fiber hose; S2, selecting and adding organic silicon resin, active diluent, initiator and additive to toluene solvent, and forming coating through mixing and stirring, wherein there are 70-75 parts by weight of organic silicon resin, 20-30 parts by weight of active diluent, 4-6 parts by weight of initiator and 0.1-0.3 parts by weight of additive; and S3, coating the glass fiber hose in S1 with the coating prepared in S2, heating and baking the glass fiber hose to get a finished silicone rubber glass fiber hose, and detecting and warehousing the finished hose. According to the preparation method of the silicone rubber glass fiber hose, a rubber sleeve produced by extrusion is selected and used, and after glass fibers are woven outside the rubber sleeve, the rubber sleeve is coated with organic silicon resin and baked to get a hose. The hose has good dielectric property, softness and flame-retardant property, and a high level of temperature resistance.

Description

technical field [0001] The invention relates to the technical field of production of glass fiber insulating sleeves, in particular to a method for preparing a silicone rubber glass fiber hose. Background technique [0002] Glass fiber insulating sleeve is an electrical insulation product, mainly used in the electrical and electrical industry, and is placed on the outside of the wire joint for insulation protection. At present, domestic fiberglass bushings are generally produced by heating and baking solvent-based insulating varnishes. The disadvantages are "two highs and one low", namely high energy consumption, high pollution and low efficiency. Insulating materials are not only a key condition for electrical products to have advanced technical indicators, but also an important guarantee for long-term safe and reliable operation of electrical products. In the existing production and processing process of the glass fiber insulating sleeve, the curing operation of the resin-...
