Abstract

The invention discloses a heat-resistant insulating resin composition which comprises the following raw materials: polypropylene resin, acrylic rubber, polyurethane rubber, polyisobutylene grafted maleic anhydride, a plasticizer, antimonous oxide, an antioxidant, an anti-aging agent, a cross-linking agent, an assistant crosslinker and silicone rubber. The heat-resistant insulating resin composition disclosed by the invention has special surface properties and low water-absorbing quality, has an effect of preventing breeding of various algae and molds, is good in mildew resistance and excellentin heat-conducting property and air permeability, has a great difference on air permeability of different gases, is odorless and tasteless, has excellent thrombosis resistance and bio-inert, and is in common use with polypropylene resin, acrylic rubber and polyurethane rubber. The heat resistance and flexibility of the insulating resin composition are further improved.

Description

technical field [0001] The present invention 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 the coating material of 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. thing. 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 and dioxin are generated. Environmental pollution problems. ...
