Description
Technical field
The present invention relates to plastic foil and the compound composite sheets that obtain such as weaving cloth, chemical fabric, leatheroid leather, artificial leather and nonwoven that high-molecular organic materials such as a kind of polyethylene or polyvinyl chloride constitute.The invention still further relates to the processing method and the special-purpose extrusion die of the composite sheet of above-mentioned plastics and cloth.
Background technology
The composite sheet of plastics of Xiao Shouing and cloth (referring to mainly that wherein plastics and cloth are bonding by cohesive materials such as PURs) generally adopts and brushes viscous coating carry out bonding between plastics and cloth in the market.Because plastics are difficult to the infiltration fusion, cause the bonding force between viscous coating and the plastics relatively poor on the one hand, this problem is more outstanding when particularly adopting regenerated plastics to be raw material, and the quality of composite sheet is descended.On the other hand, the mode general operation of employing brush applied coating is cumbersome, operating efficiency is poor, is unfavorable for producing in enormous quantities.
Summary of the invention
Technical problem to be solved by this invention provides the composite sheet of the better plastics of bonding force and cloth between a kind of each composite bed.Technical problem to be solved by this invention also comprises processing method that a kind of above-mentioned composite sheet is provided and the extrusion die of making above-mentioned composite sheet special use.
For this reason, the composite sheet of plastics provided by the invention and cloth comprises plastic layer and bed of cloth, adopts adhesive layer bonding between plastic layer and the bed of cloth, and plastic layer and adhesive layer interpenetrate the fusion one.
The processing method of the composite sheet of above-mentioned plastics provided by the invention and cloth comprises at first together to be extruded the adhesive of the plastics of molten condition and molten condition and form compound from the extrusion die of extruder under molten condition, the plastics of molten condition and the sheet material and the cloth of adhesive be will be compounded with then and rolling device pressing and cooling adopted, last rolling.
The rolling device that adopts in the processing method of the composite sheet of above-mentioned plastics provided by the invention and cloth comprises fixedly roller and movable roller, and the both ends of movable roller dispose the hydraulic pressure top respectively, and two hydraulic pressure top is connected with hydraulic pump.
The extrusion die that adopts in the processing method of the composite sheet of above-mentioned plastics provided by the invention and cloth comprises that plastics are extruded passage and adhesive is extruded passage, and plastics are extruded the outlet of passage towards extruding the outlet of passage towards mutual intersection with adhesive.
Because plastics and adhesive phase interpenetrate fusion in the composite sheet of plastics provided by the invention and cloth, both bonding forces are strengthened greatly, and general insoluble plastic layer and adhesive phase are difficult to reach the problem of degree of adhesion preferably in this series products thereby solved.In the processing method of the composite sheet of these plastics and cloth, fully take into account the fusion problem of plastics and adhesive, it is compound to allow both carry out under molten condition, make both mutually fully infiltration merge, thereby strengthen the bonding force of two aspects.In the process of the composite sheet of processing above-mentioned plastics and cloth, also adopted special-purpose extrusion die, two passages of extruding of this die head, and two channel outlet make molten condition adhesive and the molten condition plastics from a passage, extruded respectively can carry out directly compound towards cross one another structure, directly can obtain the finished product composite sheet after aspect that the adhesive of this molten condition and plastics are constituted and the cloth pressing, in whole process of production, can adopt plant equipment directly to finish, operating efficiency is high, is fit to very much produce in enormous quantities.

In each accompanying drawing: 1, extrusion die, 2, the plastics liquation extrudes passage, 3, the adhesive liquation extrudes passage, 4, fixing roller, 5, movable roller, 6, the hydraulic pressure top, 7, hydraulic pump, 8, plastic layer, 9, bed of cloth, 10, adhesive layer.
The specific embodiment
As shown in Figure 1, the composite sheet of plastics provided by the invention and cloth comprises plastic layer 8 and bed of cloth 9, adopt adhesive layer 10 bonding between plastic layer 8 and the bed of cloth 9, plastic layer 8 and adhesive layer 10 interpenetrate the fusion one, in the present embodiment the adhesive layer 10 general thermosols that adopt.
Comprise in the processing method of the composite sheet of above-mentioned plastics provided by the invention and cloth at first the adhesive of the plastics of molten condition and molten condition is together extruded and formed compound under molten condition from the extrusion die 1 of extruder, the plastics of molten condition and the sheet material and the cloth of adhesive be will be compounded with then and rolling device pressing and cooling adopted, last rolling.Wherein rolling device comprises fixedly roller 4 and movable roller 5, movable drum 5 generally can connect inlet channel, fixedly roller 4 connects outlet conduit, both form circulating cooling system, the both ends of movable roller 5 dispose hydraulic pressure top 6 respectively, two hydraulic pressure top 6 is connected with hydraulic pump 7, because hydraulic means can apply impartial dynamics to two positions under the condition of lifting surface area equalization, adopt the two ends of two 6 pairs of movable rollers 5 in hydraulic pressure top that are connected with same hydraulic pump 7 to exert pressure in the present invention, push under the condition that area equates on two hydraulic pressure top 6 and can make the 5 pressure at two ends equilibriums of movable roll tube, thus better pressing composite sheet.
As shown in Figure 2, the extrusion die 1 that adopts in the above-mentioned processing method comprises that plastics are extruded passage 2 and adhesive is extruded passage 3, towards mutual intersection, both plastics were extruded passage 2 outlets and adhesive and are extruded passage 3 outlets and directly cross in both exits, outside towards the outlet of extruding passage 3 with adhesive in the outlet that plastics are extruded passage 2.Traditional extrusion die 1 generally all is to be equipped with for extrusion plastic, and have only one to extrude passage, in improvement of the present invention, twin-channel setting makes plastics and adhesive directly carry out compound at two channel exits, state owing to both in compound all is the higher molten condition of temperature, molecule activity is more violent, therefore plastic layer and adhesive phase are very easy to permeate fusion, the bonding force of two aspects is strengthened greatly, even adopt regenerated plastics also can not influence degree of adhesion.
