Description
Technical field
The invention belongs to new material modification processing technique field, be specifically related to continuous long glass fiber reinforced POM production glass bundle response type infiltrated with molten metal equipment and wetting method.For the production of continuous long glass fiber reinforced thermoplasticity POM.
Background technology
The Length of Glass Fiber of the fiberglass reinforced thermoplasticity POM that traditional method of modifying is produced is generally less than 0.5mm, average length is 2-3mm, the stress destruction of its goods mainly glass is extracted from matrix, and glass is more short easilier to be extracted from matrix resin, and the intensity of goods is lower.Eighties of last century latter stage, external modification POM industry starts to emerge continuous long glass fiber reinforced thermoplasticity POM (LFT).Compared with traditional fiberglass reinforced thermoplasticity POM, the Length of Glass Fiber of LFT is obviously greater than the length of glass in the enhancing POM of produced in conventional processes.Because in LFT, the length of glass is longer, play the enhancing ability of glass better, thus give the higher rigidity of goods, mechanical strength, impact strength, creep resistance, simultaneously because the length of glass is longer, in shaping process, orientation is less likely to occur glass, so improve the defect of the easy buckling deformation of traditional fiberglass reinforced goods.Compared with traditional material, LFT has obviously high performance advantage and the dimensional stability of goods, so LFT material becomes the class new product just in projection in composite markets very soon.
This kind of material as the best solution to mould Dai Gang, by a large amount of for auto industry, to alleviate the weight of automobile, energy-saving and emission-reduction.As bumper, instrument board support bracket for automobile, battery load-bearing groove, chair framework, the parts such as engine bonnet.Except for except automotive field also for various fields such as household electrical appliances, environmental protection machinery, building, engineering, Aeronautics and Astronautics.
At present, the production of LFT material is based on infiltrated with molten metal method.Its technical process be glass under the effect of tractive force through the die cavity being full of melt, glass bundle scatters in die cavity under the effect of interior arrangement, is then infiltrated the inside of glass bundle by resin, fully contacts with each glass fiber yarn.Then the glass bundle through infiltration involves from the outlet of infiltration equipment glass, then is cut into the continuous long glass fiber reinforced thermoplasticity POM particle of Len req after cooling, oven dry.But the key technology of this manufacture of materials is just that can resin carry out fully infiltrating fast to glass.Key technology is embodied in: 1) glass is by infiltrating in equipment process, and the degree of wear is less, because if the degree of wear seriously easily blocks immersion equipment, causes producing instability; 2) glass is in infiltration equipment process, and fully will be infiltrated by the molten resin of inside, even resin-coating is to every root glass monofilament, because effect of impregnation is bad, the outward appearance of goods is floating fine serious, and the intensity of goods is not high simultaneously; 3) glass is faster by the linear velocity of infiltration apparatus, and the output of LFT material is higher, and the processing cost of the LFT material of Unit Weight is lower simultaneously.The infiltration equipment only having above three key technologies to reach just can be regarded as successful equipment.
Atropic company 1989 of France Patents disclosed in Chinese patent CN1021643C, is characterized by the bending infiltration runner of a similar just profound curve.The POM plastified enters in die cavity and contacts with glass, and glass bundle, when passing through crest and the trough of curved channel, scatters under tension, is then melted resin and fully infiltrates.The advantage of this Patent design is, resin is better to the effect of impregnation of glass, but there is very serious defect, namely glass fiber yarn is easily worn, and especially hauling speed is faster, and the tension force that glass is subject to is larger, more easily wear and tear, cause and produce instability, even cause stopping production.We also consult and demonstrate the granted patent of other companies domestic or colleges and universities simultaneously.There are some defects all in varying degrees, almost not having of above-mentioned 3 key technologies can be realized.
Summary of the invention
