Abstract
A thermoplastic fiber reinforced plastic board and its production is disclosed. It consists of insoluble fiber 15-60 wt% and plastic fiber 40-85 wt%. The process is carried out by mixing insoluble fiber with plastic fiber by non-woven producer, finish forming, acupuncturing to obtain fiber felt, cutting into blocks in size, coinciding, delivering it into hot press, hot pressing and forming to obtain final product.
Description
Technical field
The present invention relates to the manufacturing technology of plastics plate, specifically is a kind of thermoplastic fiber enhanced plastic plate and manufacture method thereof.
Background technology
In all types of industries and commercial device, often need to use various plastic plates, present various thermoplastics plates all be with various plastics behind hot melt, pure plastic plate with extruder for shaping, all there is certain defective in this pure plastic plate at aspects such as intensity, thermostability, weathering resistancies, and its range of application has been subjected to certain limitation.In some production practice, though also successfully fiber is added in the plastics, being subjected to the higher technology of plastics extrusion equipment will limit, and it is limited that it adds fibre weight, thereby making this series products in actual production, be subjected to certain restriction, the lifting of correlated performance is limited.
Summary of the invention
Technical problem to be solved by this invention is that the thermoplastic fiber enhanced plastic plate of a kind of intensity height, Heat stability is good and the manufacture method of this plastic plate are provided.
The composition of thermoplastic fiber enhanced plastic plate of the present invention includes the fusion-free fiber that weight percent is 15-60%, as plant fibrids such as glass fibre or cotton fibriia, brown fiber, coir, lumber fibres; Also including weight percent is the various plastic optical fibres of 40-85%, as various thermoplastic synthetic fibers such as polyethylene fibre, polypropylene fiber, movil movyl, trevira.
The manufacture method of thermoplastic fiber enhanced plastic plate of the present invention is: on the tNonwovens production unit of routine, with a kind of in the fusion-free fibers such as glass fibre or cotton fibriia, brown fiber, coir, lumber fibre or several, mix with the plastic optical fibre process, unclog and readjust moulding, become fibrefelt through acupuncture again, be cut into piece by specification again, be overlapped into certain mass area ratio, send in the thermocompressor, with material hot-forming be the plate of plane or other shape face.Hot pressed temperature can determine according to the thermoplastic temperature of different plastic optical fibres, is that 170～180 ℃, polyethylene fibre hot pressing temperature are that 150～160 ℃, movil movyl hot pressing temperature are that 190～200 ℃, trevira hot pressing temperature are 250～260 ℃ as: polypropylene fiber hot pressing temperature; Hot pressing time can determine that general mass area ratio is at 1500-2500g/m according to the superimposed mass area ratio of material
2The time, hot pressing time is 6-10 minute.
Thermoplastic fiber enhanced plastic plate of the present invention is owing to have higher fibre content, thereby can improve the intensity and the thermostability of plastic plate significantly.And use method of the present invention to make thermoplastic fiber enhanced plastic plate, owing to do not need by extrusion equipment, thereby go for the manufacturing of the plate of various fibre contents; By adjusting the gap between hot pressing pressure or control pressing plate, can control production density at 0.4～1.2g/cm
3The fiber enhanced plastic plate of various density, range of application are very extensive.In addition, because employed fiber can adopt textile industry and a large amount of useless cloth of mixed fibre of daily life depleted, the useless cloth of this class is generally synthon and cotton fibriia is mixed and made into, also have and isozygoty into a large amount of useless cloth that fiber is made, these useless cloth are all recyclable makes fiber enhanced plastic plate with the inventive method after shredding, refuse is rationally utilized, great environmental benefit is arranged.

3About the high density thermoplastic reinforcement plate.Its tensile strength 〉=25Mpa of this plate, bending strength 〉=35Mpa can be widely used in the field higher to requirement of strength, as the car light inner casing of automobile, high frame plate, civilian post liner plate etc.
Embodiment three: on the tNonwovens production unit of routine, with weight percent is 50% useless polyester and the trevira of cotton blended fabric opening fiber and 35% and 15% glass fibre, through mixing, unclog and readjust moulding, acupuncture becomes fibrefelt, and being overlapped into mass area ratio through severing again is 2000g/m
2, send in the thermocompressor, the control platen gap is 2mm, at 250-260 ℃ of following hot pressing 8-9 minute, density at 1g/cm
3About high-intensity fiber reinforced polyester plate.Its tensile strength 〉=25Mpa of this plate, bending strength 〉=40Mpa, thermostability is more than 200 ℃, good insulating, can be widely used in has certain requirement and the higher position of requirement of strength to insulation and temperature, as the lamp casing of automobile, motorcycle etc.
