Abstract

The invention relates to the technical field of high-temperature-resistant silica gel sleeves, in particular to a high-temperature-resistant silica gel sleeve. The high-strength silicone rubber is prepared from the following raw materials in parts by mass: 100-120 parts of silicone rubber, 10-15 parts of thermoplastic resin, 1.5-6 parts of a vulcanizing agent, 8-16 parts of phenyl silicone oil, 6-12 parts of titanium oxide, 3-8 parts of a plasticizer, 1-5 parts of an anti-aging agent, 10-25 parts of epoxypropane glyceryl polyether, 32-42 parts of high-aluminum clinker, 0.5-2 parts of an aluminate coupling agent, 2-5 parts of a silane coupling agent, 15-22 parts of magnesium stearate and 12-22 parts of polymethyl triethoxy silane. The high-temperature-resistant silica gel sleeve provided by the invention is simple in preparation method, low in raw material price and low in production cost, and the prepared silica gel sleeve is excellent in heat resistance and ageing resistance and can be suitable for high-temperature-resistant places.

Description

technical field [0001] The invention relates to the technical field of high-temperature-resistant silicone sleeves, in particular to a high-temperature-resistant silicone sleeve and a preparation method thereof. Background technique [0002] Silicone tube is the circulation and coating carrier of liquid, gas and other materials. It is widely used in modern industry, national defense industry and daily necessities. Silicone tube is added from raw silicone rubber to a double-roller rubber mixer or a closed kneader. Gradually add white carbon black and other additives, and after repeated refining, the product is made by extrusion. [0003] Common silicone tubes include medical silicone tubes, food grade silicone tubes, industrial silicone tubes, special-shaped silicone tubes, silicone tube accessories, etc. Under certain conditions, there is a high requirement for the high temperature resistance of the silicone tube. However, in the prior art, the ordinary high temperature res...
