Abstract

The invention relates to a high pressure resistance irradiation crosslinking environment-friendly and flame-retardant rubber and plastic composite material and a preparation method thereof. A formula of the composite material comprises raw materials in parts by weight: 15 to 45 parts of high-density polyethylene, 25 to 50 parts of elastomer resin, 10 to 30 parts of EBA, 5 to 25 parts of flexibilizer, 60 to 100 parts of flame retardant, 0.8 to 2 parts of antioxidant, 1 to 2 parts of lubricant, 0.03 to 0.1 part of crosslinking agent and 1 to 2.5 parts of crosslinking sensitizer, wherein the elastomer resin is prepared from polyurethane elastomer and ethylene propylene diene monomer elastomer, and a mass ratio of the polyurethane elastomer to the ethylene propylene diene monomer elastomer is 1 to (1 to 3). According to the composite material disclosed by the invention, the formula is improved; for example, the polyurethane elastomer and the ethylene propylene diene monomer elastomer are utilized as the elasomer resin, the high-density polyethylene and the EBA are added, meanwhile the matters of the flexibilizer, the flame retardant, the antioxidant and the like are added in an auxiliary mode; thus, the composite material disclosed by the invention has excellent wear resistance, flame resistance and heat resistance, a higher gel content can be obtained, and a pressure-resistant requirement of the material in a high-temperature welding process is met.

Description

technical field [0001] The invention relates to a high-voltage radiation-resistant cross-linked environment-friendly flame-retardant rubber-plastic composite material and a preparation method thereof. Background technique [0002] At present, with the rise of various emerging industries such as aerospace, new energy power, photovoltaic construction, etc., the standardization requirements for polymer materials are getting higher and higher, and material replacement is becoming more and more frequent. Among them, ultrasonic welding, high-temperature hot melting, etc. are also widely Used in industrial and manufacturing production. General-purpose plastics generally use polyolefin materials with a low melting point. The melting temperature is generally lower than 150°C, and the instantaneous temperature of high-temperature welding is as high as three or four degrees. During the welding process, wires and cables are prone to damage or shrink due to high temperature and external ...
