Description
Technical field
The invention belongs to new material modification processing technique field, be specifically related to continuously long aluminum fiber reinforced plastics and produce with aluminum fiber bundle response type infiltrated with molten metal equipment and wetting method.For the production of long aluminum fiber reinforced thermoplastics continuously.
Background technology
The aluminum fiber length of the aluminum fiber reinforced thermoplastics that traditional method of modifying is produced is generally less than 0.5mm, average length is 2-3mm, the stress destruction of its goods is mainly that aluminum fiber is extracted from matrix, and aluminum fiber is more short more easily to be extracted from matrix resin, and the intensity of goods is just lower.Eighties of last century latter stage, external modified plastic industry starts to emerge continuous long aluminum fiber reinforced thermoplastics (LFT).Compare with traditional aluminum fiber reinforced thermoplastics, the aluminum fiber length of LFT is obviously greater than the length of aluminum fiber in the reinforced plastics of produced in conventional processes.Because the length of aluminum fiber in LFT is longer, brought into play better the enhancing ability of aluminum fiber, thereby give rigidity, mechanical strength, impact strength, creep resistance that goods are higher, simultaneously because the length of aluminum fiber is longer, in the process of moulding, aluminum fiber is not easy to be orientated, so improved the defect of the easy buckling deformation of conventional aluminum fiber reinforced articles.Compare with traditional material, LFT has obviously high performance advantage and the dimensional stability of goods, so LFT material just becomes in composite markets the class new product in projection very soon.
This class material is as to mould the best solution of Dai Gang, by a large number for auto industry, to alleviate the weight of automobile, energy-saving and emission-reduction.As the bumper for automobile, instrument board support bracket, battery load-bearing groove, chair framework, the parts such as engine bonnet.Except for 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 be take infiltrated with molten metal method as main.Its technical process is that aluminum fiber passes the die cavity that is full of melt under the effect of tractive force, and aluminum fiber bundle scatters in die cavity under the effect of interior arrangement, then by resin, is infiltrated the inside of aluminum fiber bundle, fully contacts with each aluminum filament.Then through the aluminum fiber bundle infiltrating, from infiltrating the outlet of equipment aluminum fiber, involve, then through continuous long aluminum fiber reinforced thermoplastics particle cooling, that be cut into Len req after drying.Yet can the key technology of this manufacture of materials be just resin and to aluminum fiber, infiltrate fully fast.Key technology is embodied in: 1) aluminum fiber is by infiltrating in equipment process, and the degree of wear is less, because if the serious immersion equipment that easily stops up of the degree of wear causes producing unstable; 2) aluminum fiber, through infiltrating in equipment process, is fully infiltrated by inner molten resin, and even resin-coating is to every aluminum fiber 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) aluminum fiber 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.Only have the infiltration equipment that above three key technologies can reach just to can be regarded as successful equipment.
France atropic company 1989 is at the disclosed Patents of Chinese patent CN1021643C, and the bending that it is characterized by a similar just profound curve infiltrates runner.The plastics that plastified enter in die cavity and contact with aluminum fiber, and aluminum fiber bundle, when the crest by curved channel and trough, scatters under the effect of tension force, is then melted resin and fully infiltrates.The advantage of this Patent design is that resin is better to the effect of impregnation of aluminum fiber, but exists very serious defect, be that aluminum filament is easily worn, especially hauling speed is faster, and the tension force that aluminum fiber is subject to is larger, more easily wearing and tearing, cause production unstable, even cause stopping production.We also consult and have verified the granted patent of domestic other companies or colleges and universities simultaneously.All exist in varying degrees some defects, can realize almost not having of above-mentioned 3 key technologies.
Summary of the invention
The object of the invention is for deficiency of the prior art, provide a kind of continuous long aluminum fiber reinforced plastics to produce and equip with aluminum fiber bundle response type infiltrated with molten metal.
One object more of the present invention is, provides a kind of use to infiltrate the method that equipment infiltrates aluminum fiber bundle for continuously long aluminum fiber reinforced plastics production.
