The thermoplastic plastic fiber composite plate comprises the following components in percentage by weight: 40-60% of plastic powder and 40-60% of fiber. By adopting the thermoplastic plastic fiber composite plate and the manufacturing method of the thermoplastic plastic fiber composite plate, various types of plastic fiber composite plates compounded by different plastics and fibers different in density can be manufactured; plastic foam fiber composite plates can also be manufactured, thus meeting different requirements on plastic fiber composite plates in various industries; the thermoplastic plastic fiber composite plate has the advantages of easily available materials and low cost and has important positive significance to the promotion of the development of national economy.
Description
Technical field
The present invention relates to a kind of composite plate and manufacture method thereof, especially a kind of thermoplastic fiber composite plate and manufacture method thereof.
Background technology
Plastic optical fibre composite plate, its tension, bending resistance, shock proof intensity are all also good than pure plastic plate than pure plastic plate excellence, endurance, creep resistance, and its processing characteristics is also very superior.Thereby all trades and professions in the development of the national economy have broad application prospects.
From current manufacturing technology level both domestic and external, by the manufacture method that chopped strand is manufactured thermoplastic fiber composite plate, be mainly that fiber and plastics melting mixing are extruded into plate or are molded into part after evenly, this manufacture method, owing to being subject to the restriction of equipment and process condition, its fibre length used is shorter, general fibre length can only be in 3-6mm scope, and fiber consumption generally can only be in 30%.Thereby make the physical and mechanical property of the plate that makes be subject to certain restriction.Since this century, domestic-developed goes out a kind ofly on adhesive-bonded fabric production line, glass fibre or flaxen fiber to be mixed with polypropylene fiber through being carded to felt, again through the hot-cold low density heat plasticity fiber composite plate of density about 0.4g/cm3 that be pressed into, for automobile inner decoratire lining board.But this method polypropylene fiber price used is higher, state's tax-included price is at 13500-15000 yuan/ton at present, thereby makes product cost higher, and plastic optical fibre kind is single, is difficult to meet the needs to the requirement of product different performance.
Summary of the invention
The object of this invention is to provide a kind of thermoplastic fiber composite plate and manufacture method thereof, can overcome the technical problems such as the cost existing with chopped strand production thermoplastic fiber composite plate is at present high, kind is single, product mechanical property deficiency both at home and abroad.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: thermoplastic fiber composite plate, is characterized in that: according to percentage by weight, be fibrous by the plastic powders of 40-60%, 40-60%.
Improvement to technique scheme: described plastic powders is thermoplastic; Described fiber is the mixture of any one material in glass fibre, flaxen fiber, Chinese alpine rush fiber, carbon fiber, basalt fibre, polyster fibre or any two kinds or two or more materials.
Further improvement to technique scheme: described thermoplastic is polypropylene or polyvinyl chloride or polyethylene or polystyrene or Acrylonitrile-butadiene-styrene Copolymer or foamed polystyrene particle.
The manufacture method of thermoplastic fiber composite plate, method one, its step is as follows:
1) fibre cutting: according to product needed, fiber is cut into the scope of long 50-100mm;
2) fiber opening: fiber is become to single loosen collagen fibre through opener shredding;
3) fiber mixes: two kinds of fibers are mixed by mixer;
4) felt: on adhesive-bonded fabric production line by fiber through combing, moulding, become the fibrofelt of the mass area ratio of process stipulation;
5) acupuncture: make felt reach the packing of regulation by needing machine;
6) dusting: evenly sprinkle by the quantitative plastic powders of Process Planning through duster;
7) acupuncture again: make plastic powders evenly sneak in fibrofelt by needing machine acupuncture on the felt that has spread powder;
8) compound: by operation 6) and operation 7) felt is carried out to 2-4 dustings and composite acupuncture, the mass area ratio and the assurance plastic powders that make felt be combined into process stipulation are sneaked in fibrofelt comprehensively equably;
9) pressing plate: compound good felt becomes the size of process stipulation to send into the high temperature resistant antiseized two-sided conveyer belt of tetrafluoroethene through severing to send in hot-cold press through hot pressing, be cold-pressed into plate.
Improvement to method one: the hot pressing temperature in described step 9) is 150-260 ℃, is generally advisable to be greater than 20-30 ℃ of plastics melt temperature; Pressure is 1.5-50kg/cm2; Hot pressing time is 2.5-7 minutes.
Plastic powders in method one is polypropylene, polyvinyl chloride, polyethylene, polystyrene, Acrylonitrile-butadiene-styrene Copolymer.Adopt the plastic powders of these materials and the composite plate that method is made, can make as required the composite panel of plastic material of different densities, different plastics, different fibers.
The manufacture method of thermoplastic fiber composite plate, method two, its step is as follows:
1) fibre cutting: according to product needed, fiber is cut into the scope of long 50-100mm;
2) fiber opening: fiber is become to single loosen collagen fibre through opener shredding;
3) fiber mixes: two kinds of fibers are mixed by mixer;
4) felt: on adhesive-bonded fabric production line by fiber through combing, moulding, become the fibrofelt of the mass area ratio of process stipulation;
5) spread expanded particle: on fibrofelt, spread foamed polystyrene particle;
6) acupuncture: by needing machine, foamed polystyrene particle is sneaked in felt, and make felt reach the packing of regulation;
7) compound: by operation 5) and operation 6) felt is carried out spreading expanded particle and composite acupuncture for 2-4 times, the mass area ratio and the plastic foamed particle of assurance that make felt be combined into process stipulation are sneaked in fibrofelt comprehensively equably;
8) making sheet: compound good felt becomes the size of process stipulation to send in the die cavity of given size through severing, foams, is cooled to plate under the condition of airtight compression.
Improvement to method two: the foamable temperature in described step 8) is 100-110 ℃; Pressure is 1.5-10kg/cm2; Foamed time is 2.5-7 minutes.
Therefore plastic pellet in method two is foamed polystyrene particle, because foamed polystyrene particle particle is thicker, is difficult for entering in felt, needs first combing moulding to spread acupuncture again after particle, and the method can be made foam fibre composite plate.
Beneficial effect:
Use thermoplastic fiber composite plate of the present invention and manufacture method thereof, can produce the various plastic optical fibre composite plates of different densities, different plastics and different fiber composite, also can produce plastic foam fiber composite plate, can meet the different requirements of all trades and professions to plastic optical fibre composite plate, draw materials conveniently, cost is low, can be to promoting the development of national economy have important positive effect.
