Abstract

The invention discloses a composite plastic product and a production method thereof. The composite plastic product is characterized by comprising a plastic body and a TPU plastic thin film which combined on the surface of the plastic body and has patterns, wherein the patterns are positioned between the plastic body and the TPU plastic thin film; and the plastic body and the TPU plastic thin film are fixedly combined together by a melt layer on the surface of the plastic body; and the plastic body is made of PP, PE, ABS, PS or EV. Compared with the prior art, the composite plastic product has the advantages that: the shape is diversified, and the patterns are positioned in the plastic thin film composite layer.

Description

A kind of composite plastic product and production method thereof

Technical field

The present invention relates to a kind of plastic products and production method thereof.

Background technology

The figuratum composite plastic product of existing surface band is to be generally composited by plastics body, the figuratum plastic sheeting of being with that is compounded in plastics body surface.Composite construction has two kinds of modes, one is compound by binder, like this, pattern just can be arranged between plastics body and plastic sheeting, like this, pattern just can be subject to surperficial plastic sheeting and protect, this kind of mode, because needs adopt binder, and binder at high temperature can lose adhesive effect, therefore, compound tense can only be in moulding plastics body on carry out, and can not first on tabular plastics body, carry out, then, become by the form of thermal deformation the composite plastic product that shape is changeable, another kind is to form melting layer on plastics body surface, then utilize melting layer that compound plastic sheeting is in the above adhesively fixed, this kind of plastics body that mode adopts at present, plastic sheeting is all the plastic material of same nature, and these plastic materials are all the poor materials of light transmission, because melting layer easily destroys the pattern on plastic sheeting, and thin-film material is all the poor material of light transmission, therefore, pattern is all arranged on the outer surface of the plastic sheeting of composite plastic product, although, this kind of mode can first be carried out on tabular plastics body, then, become by the form of thermal deformation the composite plastic product that shape is changeable, but, due to directly outer exposing outside of pattern, like this, pattern is just easy to be subject to extraneous destruction, and, the third dimension of pattern is poor.

Summary of the invention

Goal of the invention of the present invention is to provide composite plastic product and the production method thereof that a kind of shape is Protean, pattern is positioned at plastic sheeting composite bed.

Composite plastic product of the present invention is to realize like this, comprise plastics body, be compounded in the figuratum TPU plastic sheeting of being with of plastics body surface, pattern is positioned between plastics body, TPU plastic sheeting, between plastics body, TPU plastic sheeting, combines by plastics body melt surface layer.TPU plastic sheeting has high ductibility, high tear resistance, anti-piercing through property, wearability, the characteristics such as light transmission is good, adopt plastics body melting layer and TPU plastic sheeting complex technique, like this, just can first make plastics body, TPU plastic sheeting composite board, then be at high temperature needed various shape by mould molding, owing to adopting plastics body melting layer and TPU plastic sheeting complex technique, when high-temperature molding, composite bed also can not separate and come off, guarantee the quality of product, pattern is positioned at TPU plastic sheeting, make pattern be subject to good protection, simultaneously, under the effect of TPU plastic sheeting light transmission, make pattern there is good third dimension, make pattern seem more attractive in appearance true.

Here, the two sides of plastics body is all compounded with the figuratum TPU plastic sheeting of inner surface belt.

Here, the material of plastics body is the wherein one in PP, PE, ABS, PS, EVA.

Composite plastic product production method of the present invention is to realize like this, comprise the thermoforming process of plastic base laminate, the hot recombination process of TPU plastic sheeting, the thermoforming process of plastic base laminate is by PP, PE, ABS, PS, after wherein a kind of plastic raw materials high-temperature fusion in EVA, be plastic base laminate setting under squeeze pressure from mould outlet extrusion molding, the hot recombination process of TPU plastic sheeting is that the plastic base laminate of firm moulding and the inner surface on being positioned at plastic plate face are pre-seted together with figuratum TPU plastic sheeting and be pressed into as composite plastic plate by upper lower compression roller rapidly, the temperature of upper lower compression roller is 50-150 ℃.Due to the firm plastic base laminate of moulding and the hot compound tense of TPU plastic sheeting, there is higher temperature, there is one deck melting layer on plastic base laminate surface, pass through melting layer, TPU plastic sheeting is just easy to be compounded in plastic base laminate surface, simultaneously, under the effect of pressure roller, be subject to the high-temperature fusion layer on plastic base laminate surface to promote TPU plastic sheeting after temperature at pressure roller and after going out pressure roller under air cooled cooling effect, TPU plastic sheeting and melting layer are cooling rapidly, the melting layer that has prevented high temperature continues TPU plastic sheeting high-temperature heating to destroy TPU plastic sheeting and pattern above.

In order to obtain the composite plastic product of various shape, the mode by heating and mould compacting is by the above-mentioned composite plastic product of being made up casing shape or lid shape of the composite plastic plate that being composited with figuratum TPU plastic sheeting and plastic base laminate.

The present invention compared with the prior art, owing to adopting melting layer complex technique composite plastic basal plate and different from this plastic basic unit sheet material matter being with figuratum TPU plastic sheeting, therefore, composite plastic product has advantages of that shape is Protean, pattern is positioned at plastic sheeting composite bed.

Accompanying drawing explanation:

Fig. 1 is process chart of the present invention;

Fig. 2 is the structural representation of the embodiment of the present invention 1;

Fig. 3 is the structural representation of the embodiment of the present invention 2.

The specific embodiment:

Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:

Embodiment 1: as shown in Figure 2, composite plastic product of the present invention comprises plastics body 1, is compounded in the TPU plastic sheeting 3 with printed patterns 2 on plastics body 1 surface, printed patterns 2 is positioned at 3 of plastics body 1, TPU plastic sheetings,

plastics body

1,3 of TPU plastic sheetings combine by plastics body 1 melt surface layer 4, and the material of plastics body 1 is the wherein one in PP, PE, ABS, PS, EVA.Plastics body 1 is lid shape or casing shape.

Embodiment 2: as shown in Figure 3, the present embodiment is that plastics body 1 is tabular on the basis of embodiment 1, the two sides of plastics body 1 is all compounded with the TPU plastic sheeting 3 of inner surface with printed patterns 2.

As shown in Figure 1, composite plastic product production method of the present invention is to realize like this, comprise the thermoforming process 5 of plastic base laminate, the hot recombination process 6 of TPU plastic sheeting, the thermoforming process 5 of plastic base laminate is by PP, PE, ABS, PS, after wherein a kind of plastic raw materials high-temperature fusion in EVA, be plastic base laminate 1 setting under squeeze pressure from mould outlet extrusion molding, the hot recombination process 6 of TPU plastic sheeting is that the plastic base laminate 1 of firm moulding is become to composite plastic plate by upper lower compression roller 7 pressings rapidly with together with the default TPU plastic sheeting 3 that is equipped with printed patterns 2 of inner surface on being positioned at 1 of plastic base laminate, the temperature of upper lower compression roller 7 is 50-150 ℃.
