Embodiment 1

[0016] Embodiment one: wherein, maleic anhydride grafted hydrogenated styrene elastomer accounted for 5% by weight, hydrogenated styrene elastomer accounted for 25% by weight, mineral extender oil accounted for 28% by weight, polyurethane elastomer accounted for 28% by weight The percentage is 32%, the inorganic nano filler accounts for 8.8% by weight, the antioxidant accounts for 0.1% by weight, the ultraviolet absorber accounts for 0.1% by weight, and the ethylene-vinyl acetate polymer accounts for 1% by weight.

Embodiment 2

[0017] Embodiment two: wherein, maleic anhydride grafted hydrogenated styrene elastomer accounted for 4% by weight, hydrogenated styrene elastomer accounted for 20% by weight, mineral extender oil accounted for 26% by weight, polyurethane elastomer accounted for 20% by weight The percentage is 40%, the inorganic nano filler accounts for 7.7% by weight, the antioxidant accounts for 0.15% by weight, the ultraviolet absorber accounts for 0.15% by weight, and the ethylene-vinyl acetate lipid polymer accounts for 2% by weight.

Embodiment 3

[0018] Embodiment three: wherein, maleic anhydride grafted hydrogenated styrene elastomer accounted for 3% by weight, hydrogenated styrene elastomer accounted for 20% by weight, mineral extender oil accounted for 30% by weight, polyurethane elastomer accounted for 37% by weight, 6.8% by weight of inorganic nano fillers, 0.2% by weight of antioxidants, 0.2% by weight of ultraviolet absorbers, and 3% by weight of ethylene-vinyl acetate polymers.

[0019] In the above examples, the hydrogenated styrene elastomer is SEBS, and SEBS is a three-block copolymerization in which polystyrene is used as the end segment and ethylene-butylene copolymer obtained by hydrogenating polybutadiene is used as the middle elastic block. SEBS does not contain unsaturated double bonds, so it has good stability and aging resistance. The model used in the present invention is one of SEBS G1650, SEBS G1651, SEBS G6933, SEBS 4033, SEBS 4055 or mixed in any proportion Various. The mineral extender oil is ...

Abstract

The invention relates to a thermoplastic elastomer for injection adhering with acrylonitrile-butadiene and styrene trepolymer, which comprises maleic anhydride grafted hydrogenated styrene elastomer, hydrogenated styrene elastomer, mineral extending oil, polyurethane elastomer, inorganic nano filler, antioxidant, ultraviolet absorber and ethylene-vinyl acetate polymer, wherein the weight percentage of maleic anhydride grafted hydrogenated styrene elastomer is 3% to 5%, the weight percentage of hydrogenated styrene elastomer is 15% to 30%, the weight percentage of mineral extending oil is 25% to 40%, the weight percentage of polyurethane elastomer is 30% to 55%, the weight percentage of inorganic nano filler is 0% to 25%, the weight percentage of antioxidant is 0.1 to 0.2%, the weight percentage of ultraviolet absorber is 0.1% to 0.2%, and the weight percentage of thylene-vinyl acetate polymer is 1% to 3%. Therefore, the thermoplastic elastomer has good surface effect and has the advantage of leading products to be more perfectly adhered.

Description

technical field [0001] The present invention relates to a thermoplastic elastomer for injection bonding with acrylonitrile butadiene and styrene terpolymer. Background technique [0002] Existing thermoplastic elastomers are generally made by adding ethylene-vinyl acetate polymer to ABS. ABS resin (acrylonitrile-styrene-butadiene copolymer, ABS is the acronym for Acrylonitrile Butadiene Styrene) is a thermoplastic polymer material with high strength, good toughness and easy processing. Because of its high strength, corrosion resistance, and high temperature resistance, it is often used to make plastic casings for instruments. However, the elastomer made of ABS added with ethylene-vinyl acetate polymer generally has the disadvantages of poor surface effect and imperfect product adhesion. [0003] Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a thermoplastic elastomer for injection bonding with acrylonitrile...
