Abstract

The invention belongs to the technical field of high polymer materials, and particularly discloses a heat-resistant insulating resin composition. The heat-resistant insulating resin composition comprises the following raw materials in parts by weight: 60-80 parts of polypropylene resin, 22-35 parts of polyacrylate rubber, 15-26 parts of polyurethane rubber, 7-15 parts of polyisobutene grafted maleic anhydride, 15-30 parts of plasticizing agent, 5-10 parts of fire retardant, 5-10 parts of antioxidant, 3-6 parts of anti-aging agent, 4-8 parts of crosslinking agent and 1-2 parts of assistant crosslinking agent. The heat-resistant insulating resin composition disclosed by the invention has excellent mechanical property, flame retardant property and high temperature resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a heat-resistant insulating resin composition. Background technique [0002] Insulated wires used for internal and external wiring of electrical and electronic equipment are required to have various properties such as flame retardancy, tensile properties, and heat resistance. Therefore, as a coating material for these insulated wires, it is known that a polyvinyl chloride (PVC) compound or an ethylenic copolymer containing a halogen flame retardant containing a bromine atom or a chlorine atom in the molecule can be used as a main component. things. However, various problems arise when the insulated wire using this covering material is discarded without proper disposal. For example, when discarded by landfill, the plasticizer and heavy metal stabilizer compounded in the covering material are leached out, and when incinerated, a large amount of corrosive gas...
