Problems solved by technology

There are two ways to compound the structure, one is to compound by adhesive, so that the pattern can be set between the plastic body and the plastic film, so that the pattern can be protected by the plastic film on the surface. agent, and the adhesive will lose its cohesive effect at high temperature. Therefore, the composite can only be carried out on the formed plastic body, not on the plate-shaped plastic body first, and then, through thermal deformation. Composite plastic products with changeable shapes; the other is to form a molten layer on the surface of the plastic body, and then use the molten layer to bond and fix the plastic film compounded on it. At present, the plastic body and plastic film used in this method are all Plastic materials of the same nature, and these plastic materials are all materials with poor light transmission. Since the melting layer is easy to destroy the patterns on the plastic film, and the film materials are all materials with poor light transmission, the patterns are all set on the composite plastic products. The outer surface of the plastic film, although this method can be carried out on the plate-shaped plastic body first, and then become a composite plastic product with various shapes through thermal deformation, but because the pattern is directly exposed, so the pattern It is easy to be damaged by the outside world, and the three-dimensional effect of the pattern is poor

Embodiment 1

[0014] Embodiment 1: as figure 2 As shown, the composite plastic product of the present invention includes a plastic body 1, a TPU plastic film 3 with a printed pattern 2 compounded on the surface of the plastic body 1, the printed pattern 2 is located between the plastic body 1 and the TPU plastic film 3, and the plastic body 1, TPU The plastic films 3 are fixed and composited together by the surface melting layer 4 of the plastic body 1, and the material of the plastic body 1 is one of PP, PE, ABS, PS, and EVA. The plastic body 1 is a lid shape or a box shape.

Embodiment 2

[0015] Embodiment 2: as image 3 Shown, the present embodiment is on the basis of embodiment 1 that the plastic body 1 is plate-shaped, and both sides of the plastic body 1 are compounded with a TPU plastic film 3 with a printed pattern 2 on the inner surface.

[0016] Such as figure 1 As shown, the production method of composite plastic products of the present invention is realized in this way, including the thermoforming process 5 of the plastic base plate, the thermal compounding process 6 of the TPU plastic film, and the thermoforming process 5 of the plastic base plate is to combine PP, PE, ABS One of the plastic raw materials among , PS, and EVA is melted at high temperature and extruded from the mold outlet under the set extrusion pressure to form a plastic base plate 1. The thermal compounding process 6 of the TPU plastic film is to make the newly formed plastic base plate 1 Together with the TPU plastic film 3 pre-set with the printed pattern 2 on the inner surfa...

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

technical field [0001] The invention relates to a plastic product and a production method thereof. Background technique [0002] Existing composite plastic products with patterns on the surface are generally composed of a plastic body and a plastic film with a pattern compounded on the surface of the plastic body. There are two ways to compound the structure, one is to compound by adhesive, so that the pattern can be set between the plastic body and the plastic film, so that the pattern can be protected by the plastic film on the surface. agent, and the adhesive will lose its cohesive effect at high temperature. Therefore, the composite can only be carried out on the formed plastic body, not on the plate-shaped plastic body first, and then, through thermal deformation. Composite plastic products with changeable shapes; the other is to form a molten layer on the surface of the plastic body, and then use the molten layer to bond and fix the plastic film compounded on it. At p...
