Embodiment 1

[0015] Embodiment 1: wherein, polypropylene elastomer accounts for 23% by weight, hydrogenated styrene elastomer accounts for 36% by weight, antioxidant accounts for 0.1% by weight, and mineral extender oil accounts for 40.9% by weight.

Embodiment 2

[0016] Embodiment 2: wherein, polypropylene elastomer accounts for 13% by weight, hydrogenated styrene elastomer accounts for 37% by weight, antioxidant accounts for 0.15% by weight, and mineral extender oil accounts for 49.85% by weight.

Embodiment 3

[0017] Embodiment 3: wherein, polypropylene elastomer accounts for 8% by weight, hydrogenated styrene elastomer accounts for 41.8% by weight, antioxidant accounts for 0.2% by weight, and mineral extender oil accounts for 50% by weight.

[0018] 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 paraffin-based alkane oil with a flash point above 200°C and a viscosity of 15-20Cps at 25°C. The antioxidant is a mixture of Antioxidant 1010 and Antioxidant 168 in a ratio of 1:1-2.

Abstract

The invention relates to a transparent thermoplastic elastomer in injection adhering with polypropylene; the transparent thermoplastic elastomer comprises a polypropylene elastomer, a hydrogenated styrene elastomer, an antioxidant and a mineral extending oil, wherein the weight percentage of the polypropylene elastomer is 8% to 23%, the weight percentage of the hydrogenated styrene elastomer is 35 to 45%, the weight percentage of the antioxidant is 0.1% to 0.2% , and the weight percentage of the mineral extending oil is 40% to 55%. Therefore, the transparent thermoplastic elastomer has high transparency and can be used for products requiring high transparency.

Description

technical field [0001] The invention relates to a transparent thermoplastic elastomer for injection bonding with polypropylene. Background technique [0002] The existing materials used to produce bonded PP generally need to add PP formula. Polypropylene (PP) is a lighter type of common plastics. It has excellent electrical properties and can be used as a heat-resistant and high-frequency insulation material. PP is a crystalline polymer. When the melt is condensed, it shows a large shrinkage rate (1.0%-1.5%) due to the large change in specific volume and high degree of molecular orientation. However, this bonded PP material has the following disadvantages: its transparency is not high, and it cannot be used in products that require high transparency. [0003] Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a transparent thermoplastic elastomer for injection bonding with polypropylene with high transparency...
