Description
The present invention relates to the manufacture method of modified with ultrahigh molecular weight polyethylene.
Ultrahigh molecular weight polyethylene(UHMWPE) UHMW-PE has other engineering plastics and the unexistent special performance of inorganic materials: high-modulus, high tenacity, high abrasion, anti stick, self-lubricating, the excellent physical and mechanical property of series such as low temperature resistant.Especially wear resistance is come out at the top in known plastic.Mortar method test shows: higher 4 times than wear-resistant plastic nylon PA, higher 5 times than plastics king tetrafluoroethylene, kinetic friction coefficient is identical with polytetrafluoroethylene PTFE, and its shock strength is also higher 1 times than impact-resistant polycarbonate.The ultrahigh molecular weight polyethylene(UHMWPE) molecular structure is same as common polythene, but can not extrude and inject processing with common process thermoplastic molding machinery.This is determined by its 1,000,000 above molecular weight, for a long time, can only use compacting one sinter molding method, or the plunger interval type is processed always.Therefore, it is used with development and is subjected to very big restriction, in the world, the country that industry is flourishing such as the U.S., Germany, Japan, the eighties worked out be suitable for processing characteristics have extruding and injection forming equipment processing ultrahigh molecular weight polyethylene(UHMWPE) of unique construction parameter, and reached industrialization phase, according to the present situation of China's national situation and plastic working application, impossibleization huge fund is introduced this not business-like as yet equipment.
Purpose based on the invention described above is to provide a kind of common plastics forming machine that is applicable to can extrude and inject the compound enhanced ultrahigh molecular weight polyethylene making method of processing.
Technical scheme of the present invention is such: active composite fortifier preparation, the glass microballon mass percent 0-45% of median size more than 200 orders, the silicon-dioxide quality per-cent 0-45% of median size more than 200 orders, all the other make active composite fortifier for the aminosilane solution of mass percent concentration 3-15% in 70 ℃ of-100 ℃ of high-speed mixing: compound enhancing ultrahigh molecular weight polyethylene is equipped with, ultrahigh molecular weight polyethylene(UHMWPE) is added behind the above-mentioned active composite fortifier of mass percent 0-45% and mass percent 10%-25% oligopolymer high-speed mixing, extruding pelletization forms then.
Above-mentioned compound enhancing ultrahigh molecular weight polyethylene can be added mass percent 3-20% phosphorus system, bromine system or antimonous oxide and their composite flame-retardant agents fully in high-speed mixing, also can add mass percent 1-5% non-ionic antistatic agent, also can add metallic elements such as mass percent 1-5% zinc or calcium.
