Description
Technical field
The invention belongs to fiber glass reinforced polyamide and preparation field thereof, be specifically related to that the height made by nylon 66, glass fibre and phosphate glass is filled, high workability matrix material and preparation method thereof.
Background technology
Nylon is a kind of macromolecular material that output is maximum in the five large-engineering plastics, kind is maximum, Application Areas is the widest, relates generally to machinery manufacturing industry, the fields such as electronic apparatus and communications and transportation.Wherein, the output of nylon 6 and nylon 66 is maximum, accounts for 90% of nylon ultimate production.This mainly is because nylon resin has the excellent over-all propertieies such as higher physical strength, thermotolerance, self lubricity, good barrier property and resistance to chemical attack.But also there is obvious defective in pure nylon: large such as water-intake rate, and the product size poor stability, flame retardant properties is general.Along with the development of automotive industry, electronic industry, people have higher requirement to the strength and stability of nylon products.Especially require to improve the physical strength of nylon products, metallic substance is as the structure product in the industrial application to replace, and the research of Reinforced Nylon emerges in an endless stream.
At present, the most representative with glass fiber reinforced nylon 66 matrix materials.Use glass fibre filled nylon-6 6 can significantly improve intensity, modulus, the thermotolerance of material, but because loading level is very large, cause fluidity of molten poor, increase power consumption and equipment loss, reduce production efficiency, increase the product molding difficulty.The processing flowability of reinforced nylon 66 matrix materials when people begin to pay close attention to the filling content that improves glass fibre.China's granted patent notification number is CN101230192B, a kind of method that improves the glass fiber-reinforced polyamide composite material flowability is disclosed: by processing expansible black lead, reduce the temperature of expanded graphite, so that expanded graphite carries out expand continuously in the course of processing, promote dispersion and the melting effect of fiber in matrix resin, so that the material melt flow rate (MFR) has improved 1-2.5 doubly.But the flowability that this invention improves the glass fiber enhanced nylon 66 system is mainly reflected in the granulation stage, and the improvement of fluidity of molten is limited during to post forming.Although the high filler loading capacity of glass has reached 50%, the flowability of material can obviously reduce, and processes expanded graphite and used poisonous small-molecule substance, is unsuitable for current requirement to environment-friendly materials.
Nineteen eighty-three, US Patent No. 4379070 made a series of phosphate glass by a step scorification.The investigator such as Otaigbe had begun about zinc alkali metal phosphate glass (zinc alkali phosphate glasses in the last few years, Tg:270-330 ℃), plumbous phosphate glass (lead pyrophosphate glasses, about Tg:390 ℃), tin fluorphosphate glass (tin fluorophosphates glasses, Tg:55-150 ℃) research of the hybrid material that forms with polymkeric substance (LDPE, PP, PS, PEI, PEEK, PPS etc.), and find the performance of many excellences.And it is at present especially outstanding with the research of tin fluorphosphate glass/polymer hybrid material, the phosphate glass that this class is special have a lower second-order transition temperature, and the approximate Newtonian fuid of performance in very broad frequency and temperature range, its viscosity has strong temperature dependency.Because low Tg is so that they are fluid state, the processing problems of having avoided high filler loading capacity to bring in the processing temperature scope of many polymkeric substance.Therefore, can by phosphate glass being joined in the system of glass fibre filling nylon 66, prepare a kind of nylon 66 composite material with high glass fibre filling amount, high workability.
