Embodiment 1

[0010] A resin composition with good mechanical properties, comprising the following raw materials in parts by weight: 2 parts of polypropylene resin, 37 parts of acrylate rubber, 29 parts of polyurethane rubber, 22 parts of polyisobutylene grafted maleic anhydride, and 23 parts of plasticizer , 15-20 parts of antimony trioxide, 12 parts of antioxidant, 8 parts of antiaging agent, 9 parts of crosslinking agent and 11 parts of co-crosslinking agent, 23 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 resi...

Abstract

The invention discloses a resin composition with good mechanical properties, which is prepared from the following raw materials: polypropylene resin, acrylate rubber, polyurethane rubber, polyisobutylene grafted maleic acid dimer, plasticizer, antimony trioxide, antioxidant, anti-aging agent, cross-linking agent, co-crosslinking agent and silicone rubber. The composition has special surface performance, low water absorption, no breeding effect on various algae and molds, good mildew resistance, good thermal conductivity and good air permeability. The composite varies greatly in permeability todifferent gases and is stinkless and tasteless. The material has excellent antithrombotic and biological inertia. The composition is commonly used with polypropylene rubber, acrylate rubber and polyurethane rubber, so that the heat resistance and the flexibility of the insulating resin composition are further improved.

Description

technical field [0001] The present invention relates to a resin composition with good mechanical properties 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 problem...
