AI Technical Summary

Problems solved by technology

However, each material has its own defects in application. For example, the low temperature resistance, compression set resistance and heat aging performance of chlorosulfonated polyethylene rubber are not high, and the material itself is relatively hard and elastic when the temperature is relatively low. Low, high brittleness, low tear resistance
At present, the existing composite insulating materials often fail to meet the requirements of long-term use and extreme conditions due to the limitations of the above-mentioned main materials, and their own performance also has many shortcomings.

Abstract

The invention discloses high-temperature-resistant fiber-reinforced insulation material and a corresponding preparation method thereof. The high-temperature-resistant fiber-reinforced insulation material is prepared from, by weight, 50-65 parts of neoprene, 40-55 parts of ethylene propylene diene monomer, 40-55 parts of transparent butadiene-styrene impact resin, 35-45 parts of panlite, 35-45 parts of methyl hydroxybenzoate, 30-40 parts of dibenzoyl peroxide, 25-35 parts of linear low-density polypropylene, 20-30 parts of polyimide fiber, 15-25 parts of polydimethyl diphenyl siloxane, 10-15 parts of hydroxyl silicone oil, 10-15 parts of white carbon black, 5-15 parts of coupling agent and 5-10 parts of antioxidant agent. By the arrangement, the prepared insulation material is resistant to high temperature and high in mechanical strength.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a high temperature resistant fiber reinforced insulating material and a preparation method thereof. Background technique [0002] An insulating material is a material used to electrically insulate a device, that is, a material capable of preventing the passage of current. It has high resistivity. It is usually a synthetic resin, which is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. By adding different components, insulating materials with different properties are obtained. Specific to the commonly used cables, it can not only play the role of insulation, but also play the role of heat insulation and anti-static. Once the insulation layer of the outer layer of the metal core is damaged, the performance of the cable will be greatly reduced. [0003] At present, the main materials commonly used as cabl...
