Abstract

The invention relates to the technical field of thermoplastic materials, in particular to a thermoplastic elastomer used for injection bonding with polypropylene materials, which comprises the following components in percentage by weight: 25% to 40% of hydrogenated styrene-based elastomer, and a compatibilizer 2 to 4%, mineral filler oil 35 to 45%, inorganic nano filler 15 to 20%, processing aid 0.2 to 1%, antioxidant 0.3 to 1%, polypropylene resin 10 to 15%, and inorganic nano filler to make this product The mechanical properties of the invention are greatly improved, and the elongation rate of injection bonding with polypropylene materials can reach more than 400%, and it also has good anti-scratch performance. Using 2 to 4% compatibilizer, it can be shot bonding with polypropylene materials so that The surface of the adhesive material is delicate and has a good touch.

Description

Technical field: [0001] The invention relates to the technical field of thermoplastics, in particular to thermoplastic elastomers used for injection bonding with polypropylene materials. Background technique: [0002] Polypropylene resin has excellent characteristics such as good mechanical properties, non-toxicity, low relative density, heat resistance, resistance to chemical solvents, easy forming and processing, readily available raw materials, and low price. It has become the fastest-growing variety among the five general-purpose synthetic resins. Widely used in home appliance shell, daily necessities, automobile manufacturing, packaging materials and other fields. However, the surface of the product produced by polypropylene resin material is smooth and hard, and it lacks flexibility and good touch in the application of some products. This is achieved by coating a layer of soft-touch rubber-plastic alloy on the surface of polypropylene resin. This rubber-plastic allo...
