Process for preparing pressure resistant radiation resistant elastomer material

Abstract

The invention discloses a process for preparing a pressure resistant radiation resistant elastomer material, and the process comprises the following steps: 1, putting 20-30 parts of a styrene thermoplastic elastomer, 15-30 parts of EPDM (ethylene-propylene-diene monomer) rubber, 10-20 parts of carbon black filled powdered styrene butadiene rubber, 9-30 parts of a plasticizer, 5-20 parts of low density polyethylene, 2-9 parts of nano SiO2, 1-5 parts of nano kaolin, 1.5-6 parts of nano talcum powder, 2-9 parts of nano montmorillonite and 0.1-1 part of an antioxidant into a high speed mixer for high speed stirring to obtain a mixture; and 2, placing the mixture into a twin-screw extruder for melting, kneading and extruding, cooling a melt output matter extruded from an extruder die head with water, and granulating to obtain the high pressure resistant thermoplastic elastomer material. The process reduces generation of space charges, effectively prevents the formation of charge accumulation in internal impurity ions, enhances the insulation performance, and improves the high pressure resistance performance of the material.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a preparation process for pressure-resistant and radiation-resistant elastomer materials. Background technique [0002] High-voltage cables are the backbone of national security and are very important for improving the country's comprehensive national strength. Laser weapons have become the key development direction of military enterprises because of their short response time, fast irradiation speed, high hit accuracy, high radiation intensity, and great destruction power. At present, the cable materials used in high-voltage cables used in laser weapons are generally silicone rubber. Although silicone rubber has certain advantages in heat resistance, waterproof, and stable electrical performance in high-temperature (alpine) environments, its processing technology needs vulcanization, which is easy Problems such as excessively high vulcanization temperature or...

At present, the cable materials used in high-voltage cables used in laser weapons are generally silicone rubber. Although silicone rubber has certain advantages in heat resistance, waterproof, and stable electrical performance in high-temperature (alpine) environments, its processing technology needs vulcanization, which is easy Problems such as too high vulcanization temperature or insufficient vulcanization occur, which cannot be recycled and are expensive
