Insulating resin composition with good flexibility

Abstract

The invention discloses an insulating resin composition with good flexibility. The insulating resin composition is prepared from the following raw materials: a polypropylene resin, polyacrylate rubber, polyurethane rubber, polyisobutene grafted maleic anhydride, a plasticizer, antimonous oxide, an antioxidant, an anti-aging agent, a crosslinking agent, an assistant crosslinker and silicon rubber.The insulating resin composition has special surface properties, is low in water absorption, has no propagation function on various algae and mold, is good in mold resistance, heat conduction and airpermeability, in addition has great air permeability differences for different gases, is non-odorous and tasteless, has very good thrombus resistance and biological nonreactivity, and can be used together with the polypropylene resin, the polyacrylate rubber and the polyurethane rubber, and the thermal resistance and the flexibility of the insulating resin composition can be further improved.

Description

technical field [0001] The present invention relates to an insulating resin composition having good flexibility. 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. 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 and dioxin are generated. Environmental pollution p...
