Abstract
The invention relates to a method for recycling a composite hemp felt leftover material. The hemp felt leftover material comprises polyester fiber with double groups of components, wherein the core layer of the polyester fiber adopts PET, and the surface layer adopts COPET. The method comprises the following steps: firstly, crushing the recycled composite hemp felt leftover material through a crushing mill, secondly, performing heating extrusion to the recycled composite hemp felt leftover material through a screw machine, with the hot extrusion temperature being 120 to 150 DEG C, thirdly, extruding the material through a flat die, with the die orifice temperature being 80 to 100 DEG C, fourthly, rolling and extending the material through a roller press, and fifthly, performing trimming formation. With adoption of the method, the purposes of reducing waste and environment pollution can be achieved.
Description
Technical field
The present invention relates to a kind of method of numb felt leftover bits recycling, is mainly the method for the compound numb felt corner recycling used of a kind of automotive upholstery.
Background technology
Extensive utilization along with natural complex fiber material on automobile, met the requirement of automobile environment-protection, but a large amount of productions of complex fiber material have produced a large amount of leftover bits, can't recycle, and cause the wasting of resources, produce new environmental pollution simultaneously.
Number of patent application provides a kind of numb felt composite plate for 2013103351912, and it contains a large amount of natural fibers, if leftover pieces are abandoned, causes the wasting of resources, very unfortunate undoubtedly.
Traditional numb felt leftover pieces, in the recycling process, well are bonded together in order to make particle, and the step of adding tackifier is generally arranged, but the use of tackifier: 1) improved processing cost; 2) increased the chance that leftover pieces are polluted, made the not environmental protection of leftover pieces of producing, and can bring very big inconvenience to subsequent treatment, the discharge meeting of tackifier brings pollution to environment.
Summary of the invention
The present invention is directed to above-mentioned defect, purpose is to provide a kind of method that reclaims compound numb felt leftover pieces recycling, thereby reaches the purpose that reduces waste, reduces environmental pollution.
The technical solution used in the present invention is for this reason: described numb felt leftover bits and pieces of material includes two polyster fibres that divide that form, and its sandwich layer is that PET, top layer are COPET; According to following steps, carry out:
1) the useless numb felt leftover pieces that reclaim are pulverized through pulverizer;
2) added hot extrusion by screw machine again, its extrusion temperature 120-150 ℃;
3) by flat mould, extrude; Its die temperature is 80-100 ℃;
4) by the roll squeezer roll-in, extend, its roll-in rotating speed is 45-55rpm;
5) prune moulding.
1), in step, numb felt leftover pieces are ground into the wide fragment of 1-2cm.
It consists of natural fiber 60-70%, polyster fibre 30-40% described numb felt leftover bits and pieces of material group; Described polyster fibre is to divide two the composition, and its sandwich layer is that PET, top layer are COPET.
4), 5) increase following steps between step: cover glued membrane on the numb felt sheet material of moulding, be convenient to bonding leather or decorate flannelette.
Advantage of the present invention is: the characteristics of 1) utilizing the numb felt leftover pieces of processing, utilize COPET fusing point lower (110 ℃), viscosity characteristics preferably, when it pushes, do not need to add tackifier, the self-adhesion of leftover pieces own forms an integral body, and the numb felt of recovery does not add any additive in whole process because of it, thereby is not subject to any pollution, its quality can not descend, and produces great economic benefit; 2) processing technological flow of the present invention is short simultaneously, has high efficiency characteristics; 3) the extrusion temperature 120-150 ℃ selected during screw extruding of the present invention, it is a little more than the fusing point of COPET, and lower than the fusing point of sandwich layer PET, the one temperature reduces the consumption that can reduce the energy, two by the adhesive property of COPET, good advantage fully demonstrates out for it, also can not affect because of excess Temperature the performance of sandwich layer PET simultaneously; Therefore the present invention takes full advantage of the characteristics of the material of leftover pieces own, utilize physical change that broken leftover pieces are again bonding in aggregates, whole process does not need to add any outside material, thus whole process the most totally, environmental protection, also can keep the characteristics of leftover pieces itself; 3) temperature of the flat mould of the present invention is 80-100 ℃, fusing point a little less than COPET, this temperature makes COPET keep certain viscosity, make the leftover pieces can be because of the phenomenon of the inadequate fracture of viscosity when extending, the loss of leftover pieces also can not occur because of being melted, therefore the selection of this temperature is resulting according to actual conditions, Tai Gao or the too low process that all can affect the leftover pieces recovery.
In sum, processing procedure of the present invention has the high characteristics of product quality that treatment effeciency is high, processing cost is low, recovery obtains.
