Embodiment 1~2

[0037] According to the embodiment formula listed in Table 1 ("parts" in the table all refer to parts by weight, the same below), at first SEBS resin and mineral oil are fully mixed in a prescribed ratio, and mineral oil is completely absorbed by SEBS resin to obtain Oil-extended SEBS, and then mix the oil-extended SEBS with thermoplastics, tackifying resins, fillers, and composite stabilizers in a high-speed mixer. The mixed materials are evenly fed into the twin-screw extruder by the feeder. The temperature of the twin-screw extruder is set at 190-220°C, the screw speed is set at 280 rpm, and the feeding speed is set at Set at 30 rpm. After twin-screw high-speed shearing, mixing and plasticizing, extruding from the head of the extruder, drawing, cooling, pelletizing, drying, and then punching boards for performance testing, the results are shown in Table 1.

Abstract

The invention provides a thermoplastic elastomer composition for covering a nylon material. The thermoplastic elastomer composition comprises the following components in part by weight: 10 to 45 parts of basic resin that is SEBS and / or SEEPS; 20 to 50 parts of mineral oil; 0 to 15 parts of thermoplastic plastics which are polyethylene or polypropylene; 5 to 35 parts of thickening resin comprising composite resin of polyethylene-maleic anhydride grafts and EDPM-anhydride grafts; 20 to 50 parts of filling agent; and stabilizer accounting for 0.1 to 0.5 percent of the total weight percent of the five raw materials. The thermoplastic elastomer TPE material is excellent in oil resistance and heat aging resistance and widely applicable to a tool handle with strict application requirements.

Description

technical field [0001] The invention relates to the field of polymer materials, and is a thermoplastic elastomer material that can be firmly coated and bonded to the surface of nylon materials by secondary injection molding or double-color injection molding with nylon materials, and has excellent oil resistance and heat aging resistance. . Background technique [0002] Thermoplastic elastomer TPE material has the high elastic properties of rubber at room temperature, and can be plasticized and formed under high temperature conditions. It has good processing fluidity of plastics and combines the excellent properties of thermoplastics and rubber. In addition to injection molding alone, it can also be firmly coated on various general-purpose plastics and engineering plastics materials, such as PP, PE, PS, PC, ABS, etc., by secondary injection molding. Moreover, thermoplastic elastomers are environmentally friendly, non-toxic, excellent colorability and 100% recyclable, so they...
