Description
Technical field
The invention belongs to new material modification processing technique field, be specifically related to continuous long glass fiber and strengthen PPO production glass fiber bundle response type infiltrated with molten metal equipment and wetting method.The production of thermoplasticity PPO is strengthened for continuous long glass fiber.
Background technology
The glass fibre length of glass fiber reinforcement thermoplasticity PPO that traditional method of modifying produces is generally less than 0.5mm, average length is 2-3mm, the stress destruction of its goods mainly glass fibre is extracted from matrix, and glass fibre is the shortest more easy extracts from matrix resin, and the intensity of goods is the lowest.Eighties of last century latter stage, external MODIFIED PP O industry starts to emerge continuous long glass fiber and strengthens thermoplasticity PPO(LFT).Compared with traditional glass fiber reinforcement thermoplasticity PPO, the glass fibre length of LFT is significantly greater than the length of glass fibre in the enhancing PPO of produced in conventional processes.Owing in LFT, the length of glass fibre is longer, preferably play the enhancing ability of glass fibre, thus give the higher rigidity of goods, mechanical strength, impact strength, creep resistance, simultaneously because the length of glass fibre is longer, during molding, orientation is less likely to occur glass fibre, so improving conventional fiber glass to strengthen the defect of the easy buckling deformation of goods.Compared with traditional material, LFT has the dimensional stability of the highest performance advantage and goods, so LFT material is quickly become in composite markets just at a class new product of projection.
This kind of material, as to mould the best solution of Dai Gang, is largely used to auto industry, to alleviate the weight of automobile, energy-saving and emission-reduction.As for the bumper of automobile, instrument board support bracket, accumulator load-bearing groove, chair framework, the parts such as engine bonnet.The various fields such as household electrical appliances, environmental protection machinery, building, engineering, Aeronautics and Astronautics it are additionally operable in addition to for automotive field.
At present, the production of LFT material is based on infiltrated with molten metal method.Its technical process is glass fibre die cavity through full melt under the effect of pull strength, and glass fiber bundle scatters in die cavity under the effect of interior arrangement, is then infiltrated the inside of glass fiber bundle by resin, and each glass fiber is fully contacted.Be then passed through infiltration glass fiber bundle from infiltration equipment glass fibre outlet involve, more cooled, dry after be cut into Len req continuous long glass fiber strengthen thermoplasticity PPO granule.But the key technology of this manufacture of materials is that can resin carry out the most quickly infiltration to glass fibre.Key technology is embodied in: during 1) glass fibre is equipped by infiltration, the degree of wear is less, because if the degree of wear the most easily blocks immersion equipment, causes producing instability；2) glass fibre is during infiltration equipment, fully will be infiltrated by internal molten resin, even resin-coating to every glass fiber single filament, because effect of impregnation is bad, the outward appearance of goods is floating fine serious, and the intensity of goods is the highest simultaneously；3) glass fibre is the fastest by the linear velocity of infiltration apparatus, and the yield of LFT material is the highest, and the processing cost of the LFT material of Unit Weight is the lowest simultaneously.The infiltration equipment that only three above key technology is attained by just can be regarded as successful equipment.
Atropic company 1989 of France, at Patents disclosed in Chinese patent CN1021643C, is characterized by the bending infiltration runner of the most profound similar curve.The PPO plastified enters in die cavity and fiberglass particle contact, and glass fiber bundle, when by the crest of curved channel and trough, scatters under tension, is then melted resin and fully infiltrates.The advantage of this Patent design is, resin is preferable to the effect of impregnation of glass fibre, but there is the most serious defect, i.e. glass fiber is easily worn, and especially hauling speed is the fastest, and the tension force that glass fibre is subject to is the biggest, the most easily wear and tear, cause production instability, even cause stopping production.We also consult and demonstrate other companies domestic or the granted patent of colleges and universities simultaneously.There are some defects the most in varying degrees, it is possible to realize above-mentioned 3 key technologies almost without.
Summary of the invention
