一种用于尼龙粘合包胶的TPE合金及其制备方法
摘要：
本发明公开了一种用于尼龙粘合包胶的TPE合金，包含以下按质量百分数计的组分：热塑性弹性体30-45%，工程塑料10-20%，增塑剂10-35%，相容剂10-15%，填充剂10-15%，助剂1-2%，热塑性弹性体为苯乙烯类热塑性弹性体、热塑性聚氨酯弹性体、聚酯类弹性体中的一种或几种的组合物，工程塑料为聚丙烯、聚乙烯、聚苯乙烯、聚碳酸酯、尼龙6、尼龙66中的一种或几种，本发明还公开上述TPE合金的制备方法。本发明通过将热塑性弹性体与工程塑料配合，且各组分在熔融挤出过程中发生协同作用，使TPE合金的硬度、拉伸强度及断裂伸长率等力学性能优异，并对不同型号的尼龙包胶粘合性能好，适于工业化生产。
摘要（英）：

The invention discloses a thermoplastic elastomer (TPE) alloy for nylon adhesive encapsulation. The TPE alloy comprises the following components in percentage by mass: 30-45 percent of TPE, 10-20 percent of engineering plastic, 10-35 percent of plasticizer, 10-15 percent of compatilizer, 10-15 percent of filler and 1-2 percent of aid, wherein the TPE is one or a mixture of several in a styrene thermoplastic elastomer, a thermoplastic polyurethane elastomer and a polyester elastomer; the engineering plastic is one or more selected from polypropylene, polyethylene, polystyrene, polycarbonate, nylon 6 and nylon 66. The invention also discloses a method for preparing the TPE alloy. The TPE is matched with the engineering plastic, and the components have a synergistic effect in the melt extrusion process, so that the mechanical properties, such as hardness, tensile strength and elongation at break, of the TPE alloy are excellent, and the TPE alloy is high in adhesion property of different models of nylon encapsulations and is suitable for industrial production.
