Description
The method that the present invention relates to a kind of fluid bed and prepare fiber reinforced thermolplastic composite material by this fluid bed.
Fiber reinforced thermolplastic composite material (Glass Mat Reinforced Thermoplastic) is called for short GMT, be a kind of be matrix with the thermoplastic resin, be the composite of reinforce with long fibre or continuous fiber.With dissimilar fibers and thermoplastic resin matrix, can form diversified GMT material.Because polypropylene has the good ratio of performance to price, be a kind of most widely used thermoplastic matrix therefore.
Developed multiple GMT sheet preparation method at present both at home and abroad, and industrialization, (U.S Patent 3 684 645 (1969) as United States Patent (USP), Temple, C.S., Matthews, J.R.) disclosed melt impregnation is with (U.S Patent 4 481 075 (1984), Dailly, C., Gomez, D.) disclosed slurry attitude infusion process, also have (U.S Patent 3 742 106 (1973) .Price, the fluid bed powder art infusion process that R.V) is disclosed etc. in addition.
Melt impregnating process is that two layers of glass felt are pressed together in three layers of thermoplastic resin, in the middle of be the thermoplastic resin of fusion, outermost layer can be a film, it also can be the resin of fusion, this sandwich is sent into double-steel belt pressing machine, pressurization cooling is then cut out at last and is cut under the temperature conditions that is higher than the resin fusion.Generally speaking, have only when matrices of composite material amplified medium is fully formed between dipping and matrix and the amplified medium preferably the interface in conjunction with after, just can make full use of the physical characteristic of glass fibre high strength, high-modulus, reach fibre-reinforced effect.The key parameter of this method is the dipping speed of melt to glass mat, because the complicated fine and close geometry of the high viscosity of thermoplastic resin melt and glass mat, finish the dipping process of melt, need long dip time and higher impregnation pressure glass mat.Even so, resin melt also is difficult to reach dipping in the fibre bundle.
Slurry attitude impregnation technology is to develop on the basis of papermaking equipment, the glass fibre of length between 6～25mm is dispersed in the water, add toner and a kind of emulsion, these ingredients suspension are in water, after adding flocculant, powder and emulsion are condensed, become on the screen sieve to separate at hydraulic pressure, the felt that forms is tight in the temperatures that is higher than the resin fusion, makes the GMT sheet material.This method is difficult to it is eliminated fully owing to add a large amount of chemical assistants in the operation, remains in auxiliary agent on the glass fibre and can reduce interface bond strength between matrix and the fiber.Also there is the problem that waste water reclaims and purifies in this technology simultaneously.
The fluidized bed powder infusion process is to disperse the back by a fluid bed glass fiber bundle, toner is because the effect of Electrostatic Absorption and attached to fiberglass surfacing, the method that coats by heating or similar polymers film is made the preimpregnation band then, at last with this preimpregnation band braiding and send into double-steel belt pressing machine or the platen-press preheating is pressed into sheet material.This method equipment complexity is difficult for realizing industrialization.
Therefore providing a kind of new equipment and the new method for preparing GMT, is that people institute is very expected.
One of purpose of the present invention is to disclose a kind of fluid bed with the moving structure of stirring-spraying, to overcome the existing equipment complex process, is difficult for realizing industrialized defective;
