一种用于包覆粘合PET的TPE复合材料
摘要：
一种用于包覆粘合PET的TPE复合材料，包括热塑性弹性体、增塑剂、工程塑胶、相容剂、填充剂和助剂，原料由以下重量份的组份组成：热塑性弹性体：30‑40份、增塑剂：5‑25份、工程塑胶：15‑25份、相容剂：10‑20份、填充剂：10‑15份、助剂：0.01‑0.1份。在TPE合金体系中采用了热塑性弹性体和工程塑胶组合以增加体系的极性和耐温性从而提高TPE复合材料与PET的界面粘接力，解决了TPE二次注塑粘接PET容易剥离的问题。同时提高了TPE合金材料的强度、模量和耐温性能，同时也降低了包覆成型PET的温度，增加了其实用性和商业价值。采用的相容剂，提高了TPE合金体系的相容性，不仅提升了复合材料的强度、模量，而且进一步提高TPE合金与PET的粘接强度。
摘要（英）：

The invention discloses a TPE (thermoplastic elastomer) composite used for coating and adhering a PET (polyethylene terephthalate). The TPE composite comprises the following components by weight: 30-40 parts of a thermoplastic elastomer, 5-25 parts of a plasticizer, 15-25 parts of an engineering plastic, 10-20 parts of a compatilizer, 10-15 parts of a filler, and 0.01-0.1 part of an assistant. The combination of the thermoplastic elastomer and the engineering plastic is adopted in a TPE alloy system to improve the polarity and the temperature tolerance of the system, so that the interface adhesive strength of the TPE composite and the PET is improved, and the problem that the PET is easy to peel off when the PET is adhered through secondary injection molding of the TPE is solved. Moreover, the strength, the modulus and the temperature resistance of a TPE alloy material are improved, the temperature of the over molding PET is also reduced at the same time, and the practicality and the commercial value of the TPE composite are improved. The adopted compatilizer improves the compatibility of the TPE alloy system, the strength and the modulus of the composite are improved, and the adhesive strength of the TPE alloy and the PET is further improved.
