Abstract
The invention provides a preparation method of wear-resistant polyphenylene sulfide composite aggregates with high purity and forming degree. The preparation method is characterized by comprising the steps of purifying polyphenylene sulfide resin raw materials; carrying out oxidation and heat exchange treatment on the purified polyphenylene sulfide resin raw materials; adding 4% of potassium titanate fibers subjected to infiltration surface treatment, 18% of polytetrafluoroethylene powder subjected to infiltration surface treatment and 4% of an inorganic wear-resistant filling agent into the raw materials treated in the second step; meanwhile, adding a heat stabilizer, a toughening agent, an antioxidant, a filling agent and a flatting agent; sufficiently and uniformly mixing the mixture in a high-speed mixer to obtain a polyphenylene sulfide resin premixture and reinforced fibers; purifying the premixture and the reinforced fibers; forming by mixing and extruding the purified premixture and reinforced fibers by using a co-rotating double-screw extruder, chopping, and mounting an air conditioning system at the discharging end to ensure that the discharged materials are formed in the first time.
Description
Technical field
The present invention relates to a kind of materials processing technology, specifically refer to the manufacture method of the wear-resisting composite granule of a kind of polyphenylene sulfide.
Background technology
Polyphenylene sulfide (PPS)----English name Poly Phenylene Sulfide abridges (PPS), it is a kind of polymer of high-molecular linear, its combination property is very superior, it is the first kind of special engineering plastics, be called as the sixth-largest engineering plastics, also being one of " eight is large " aerospace material, is conventional industries more one of the New Times and the indispensable new material of high, precision and frontier technical development.Be widely used in Aero-Space, military field, electronic apparatus., petrochemical industry, machinery, instrument, household electrical appliance, food medicine, automobile lamp, connector, sensor, textile machinery accessories, anticorrosion equipment etc.PPS Main Feature has: high temperature resistant, corrosion-resistant, radiation hardness, wear-resisting, nontoxic, fire-retardant, electrical property is excellent, good mechanical property, dimensionally stable, machine-shaping property are good, with metal and nonmetal binding performance good etc.
Because polyphenylene sulfide has above-mentioned various good characteristics, Ge great factory competitively produces, and production procedure main in prior art is as follows: fully mix in homogenizer after polyphenylene sulfide being added high-abrasive material graphite powder, flexibilizer, antioxidant, filler, levelling agent and obtain polyphenylene sulfide premix; The premix of gained polyphenylene sulfide and mass fraction be 40% to be shaped through double screw extruder mixing extrusion through the glass fibre of surperficial coupling processing, to cool, pelletizing forms finished product modification composite granule.But these methods are meticulous all not, the polyphenylene sulfide produced wear-resisting composite granule shaping degree and purity are not high.
Summary of the invention
The technical problem to be solved in the present invention is, provides the manufacture method of the wear-resisting composite granule of the polyphenylene sulfide of a kind of purity and shaping Du Genggao.
For solving the problems of the technologies described above, technical scheme provided by the invention is: the manufacture method of the wear-resisting composite granule of a kind of polyphenylene sulfide, it comprises the steps:
The first step, purifies polyphenylene sulfide resin fat raw material;
Second step, by the polyphenylene sulfide resin fat raw material after purification through heat of oxidation crosslinking Treatment;
3rd step, the process adding 4% in the raw material through second step process infiltrates surface-treated potassium titanate fibre, and 18% pass through infiltrates surface-treated polytetrafluoroethylene powder, the inorganic wear-resistant filler of 4%; Add heat stabilizer, flexibilizer, antioxidant, filler, levelling agent more simultaneously;
4th step, fully mixes the mixture in the 3rd step and obtains polyphenylene sulfide premix and increase fiber in homogenizer;
5th step, carries out purification processes to the premix in the 4th step and increase fiber;
6th step, by the premix after purifying with increase fiber through parallel dual-screw extruding machine mixing extrusion shaping pelletizing, and to install an air-conditioner system at discharge end, ensure that the discharging very first time is shaped.
As preferably, the size that described polytetrafluoroethylene powder and potassium titanate fibre use is AEO compounds size JFC.
As preferably, described inorganic wear-resistant filler is nanoscale alundum (Al2O3).
