Embodiment 1

[0010] An insulating resin composition with good flexibility, comprising the following raw materials in parts by weight: 1 part of polypropylene resin, 22-35 parts of acrylate rubber, 15-26 parts of polyurethane rubber, 8 parts of polyisobutylene grafted maleic anhydride 21 parts of plasticizer, 15-20 parts of antimony trioxide, 11 parts of antioxidant, 5 parts of anti-aging agent, 4-8 parts of crosslinking agent and 3-5 parts of co-crosslinking agent, 21 parts of silicone rubber

[0011] The invention is a crystalline polymer with regular structure, light weight, good mechanical properties and good heat resistance; acrylate rubber has excellent heat resistance and ozone resistance, and will not change color due to ultraviolet rays. Contains a strong shuttle base, which makes it resistant to aliphatic hydrocarbons and oil; polyurethane rubber has high hardness, good strength, high elasticity, high wear resistance, tear resistance, aging resistance, ozone resistance, radiation r...

Abstract

The invention discloses an insulating resin composition with good flexibility. The composition comprises polypropylene resin, acrylate rubber, polyurethane rubber, polyisobutene grafted maleic anhydride, a plasticizer, antimonous oxide, an antioxidant, an anti-aging agent, a cross-linking agent, an assistant crosslinker and silicon rubber. The composition has special surface performance, is low inwater absorption, has no breeding effect on various algae and molds and is good in mildew resistance, thermal conductivity and air permeability; difference of air permeability to different kinds of gas is large, and the composition is odorless, tasteless and excellent in antithrombotic property and biological inertia; the acrylate rubber and the polyurethane rubber are used together, so that theheat resistance and flexibility of the insulating resin composition are further improved.

Description

technical field [0001] The present invention relates to an insulating resin composition with 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 pro...
