Abstract
A process for granulating the polyphenyl thioether fibre composition modified by mixture of teflon, polyfluoroethylene propylene and polyphenyl thioether for injection includes such steps as immersing carbon fibre in polyphenyl thioether suspension, drying, fusion infiltration, cooling to obtain thicker fibre, granulating the mixture of ultrafine teflon powder, polyphenyl thioether resin powder and concentrated polyfluoroethylene propylene suspension, coating them around said thicker fibre using granulating machine, cooling and cutting.
Description
The present invention relates to injection polytetrafluoroethylene (PTFE), perfluoroethylene-propylene and polyphenylene thio-ether blend modified polyphenylene thio-ether fibre composite material prilling method and technology field.
The early existing document announcement of polytetrafluoroethylene (PTFE) and polyphenylene sulfide blended resin fibre composite, owing to polytetrafluoroethylene (PTFE) has only the crystallization fusion not have melt-flow when the high temperature, free surface energy is very low and cannot not have stickingly, interlaminar resin after blend can only the weak interface coating make the wearability of material bad, and polytetrafluoroethylene (PTFE), perfluoroethylene-propylene and polyphenylene thio-ether blend modified polyphenylene thio-ether fibre composite material were not all met report at home and abroad.
The purpose of this invention is to provide a kind of injection polytetrafluoroethylene (PTFE), perfluoroethylene-propylene and polyphenylene thio-ether blend modified polyphenylene thio-ether fibre composite material prilling method, adopt material that this method makes except that having polytetrafluoroethylene (PTFE) and polyphenylene sulfide blended resin fibre composite good self lubricity, corrosion resistance and hear resistance, also have good mechanical property and abrasion performance.
The present invention is achieved in that and gets polyphenylene sulfide resin cosmetics, ethanol and distilled water, earlier polyphenylene sulfide being put into is with the ball mill porcelain jar of porcelain ball to dry grind broken, dry grind after broken the finishing, again ethanol and distilled water are put into porcelain jar and carry out wet-milling, make polyphenylene sulfide suspension, carbon fiber or glass fibre or carbon fiber are gone up polyphenylene sulfide suspension with the fiber that glass fibre mixes mutually by the impregnator dipping, through the air drying, the fiber roving that is soaked with polyphenylene sulfide is made in heating and melting and hardening by cooling, by weight percentage, get ultra-fine polytetrafluoroethylene powder 10-15% and polyphenylene sulfide resin cosmetics 40-50% puts into the double-vane screw mixer, these two kinds of powder are mixed, progressively add perfluoroethylene-propylene concentrated suspension liquid (butt thing meter) 5-15% then, be mixed into plaster material, this material is put into oscillating granulator, this material is made plasticity strip material grain, put into the baking oven heat drying then, take out cooling and fragmentation at last and obtain containing polytetrafluoroethylene (PTFE), the particle of polyphenylene sulfide and perfluoroethylene-propylene; This particle is put into exhaust list screw pelletizer hopper; kiss-coating at this machine coats the head place; finish that the fiber roving that is soaked with polyphenylene sulfide is coated polytetrafluoroethylene (PTFE), polyphenylene sulfide and the perfluoroethylene-propylene work of going up, at last above-mentioned material is made injection polytetrafluoroethylene (PTFE), perfluoroethylene-propylene and polyphenylene thio-ether blend modified polyphenylene thio-ether fibre composite material material grain through cooling and cut-out.
Advantage of the present invention is: method of manufacturing technology is simple, the material of being made by this method has good self lubricity, and corrosion resistance, hear resistance, mechanical property and abrasion performance at high temperature have high strength and high elastic modulus, creep resistance is good, the product size good stability.
Below in conjunction with embodiment, the present invention will be further described:
Get 20 kilograms in polyphenylene sulfide resin cosmetics, 40 kilograms of 40 kilograms of ethanol and distilled water, earlier polyphenylene sulfide is put into the ball mill porcelain jar of band porcelain ball, it is broken at room temperature to dry grind, time is 10 hours, again ethanol and distilled water being put into porcelain jar after dry grinding is finished carries out wet-milling and makes polyphenylene sulfide suspension, get 20 kilograms of fibers that carbon fiber or glass fibre or carbon fiber and glass fibre mix mutually and go up polyphenylene sulfide suspension, make the fiber roving that is soaked with polyphenylene sulfide through air drying, heating and melting and hardening by cooling by the impregnator dipping; Get 40 kilograms in 10 kilograms of ultra-fine polytetrafluoroethylene powders and polyphenylene sulfide resin cosmetics, put into the double-vane screw mixer, these two kinds of powder are mixed, getting 5 kilograms of perfluoroethylene-propylene concentrated suspension liquids then progressively adds in the mixer, be mixed into plaster material, this material is put into oscillating granulator, this material is made plasticity strip material grain, putting into baking oven then heats, oven temperature is 150 ℃-200 ℃, and be 4-5 hour drying time, and dried material is heated to 350 ℃ in baking oven, 3-5 hour, the melt index (MI) that makes material is 175 ± 50 o'clock, takes out cooling immediately, and cooled material is through fragmentation, make it can pass through 2 * 2mm sieve aperture, make and contain polytetrafluoroethylene (PTFE), the particle of polyphenylene sulfide and perfluoroethylene-propylene; This particle is put into exhaust list screw pelletizer hopper; kiss-coating at this machine coats the head place; temperature is 300 ℃-320 ℃; finish the fiber roving that is soaked with polyphenylene sulfide is coated upward polytetrafluoroethylene (PTFE); polyphenylene sulfide and perfluoroethylene-propylene work; at last above-mentioned material is cooled off through air; sclerosis; send into rotation and cut off that to be cut into length in the machine be 5-6mm injection polytetrafluoroethylene (PTFE); 72.67 kilograms of perfluoroethylene-propylene and polyphenylene thio-ether blend modified polyphenylene thio-ether fibre composite material material grains, this material is suitable for making bearing bracket stand; mechanical seal ring; valve plate; blade; pneumatic valve body; products such as pump skeleton and impeller.
