新型PEP填充母料的研究

Study of New Type PEP Multibase

PEP填充母料是福建师范大学高子分研究所近年开发的聚烯烃用新型填充母料专利产品。其特点是以铝酸酯偶联剂为改性剂,以高分子(LDPE树脂)、大分子和低分子复合组分为填料载体加工而成的,已在全国范围内广泛得到采用。

In this paper, hygroscopic property, photooxidation and heat-oxidation stabilities of PEP multibase were investigated. And influence of PEP multibase on proeassing theological properties and on product properties of polyethylene and polypropylene was also investigated by Brabender Plastiegrder in this paper. The results of the experiment show that PEP Multibase offers better heat stability and lower water absorption than APP. PEP Multibase can improve the processing melt flow of filling resins, has good compatibility with PE and PP, and shorten the extension of plasticizing time of PE or PP. PEP is used for PP weaving thread for woven bags, packaging belts and PE extruded pipes. When filling weight is 18%, properties of the producs accord with the demands, which can greatly decrease the cost.
