The utility model discloses further set up to: the surface layer is provided with a coating layer, and the coating layer covers a part of the surface layer.

Through adopting above-mentioned technical scheme, panel itself needs to have the characteristics of show, and the dope layer can adopt the colour that does not decorate the composite sheet, and other people of being convenient for perceive, the producer of also being convenient for discerns this composite sheet.

The utility model discloses further set up to: and a transparent plastic layer which covers the coating layer and the surface layer and is used for preventing scratches is arranged on the coating layer.

Through adopting above-mentioned technical scheme, the surface course adopts the PC plastic layer, because the scratch is all stayed easily to PC plastic layer and dope layer, covers setting up of transparent plastic layer and has played the effect of protection dope layer and PC plastic layer.

The utility model discloses further set up to: the transparent plastic layer is provided with a plastic film layer which is transparent and used for flexible packaging.

Through adopting above-mentioned technical scheme, plastic film layer has waterproof effect.

The utility model discloses further set up to: three sides of the body are provided with transparent glue layers, and the transparent glue layers are coated on three sides of the body.

Through adopting above-mentioned technical scheme, transparent glue layer realizes fixedly through the side of coating at the body, and transparent glue layer has the characteristics that are difficult to the hand of hindering. One side of the body is not provided with a transparent adhesive tape layer, so that other people can observe the layer structure of the body conveniently.

To sum up, the utility model discloses reduce the holistic manufacturing cost of body with the intermediate level of leftover bits as the body, improved the use value of leftover bits and still reduced manufacturing cost.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The embodiment discloses a composite board for a luggage, which comprises a body 1, wherein the body 1 comprises a bottom layer 2, a waste layer 3 and a surface layer 4 from bottom to top as shown in fig. 1 and 2. The waste material layer 3 is made of leftover materials, and the bottom layer 2 and the surface layer 4 are made of plastics with comprehensive performance higher than that of the leftover materials. The leftover bits that will grow in the production and processing set up as the intermediate level of composite sheet, compare and all adopt the high composite sheet of comprehensive properties, under same thickness, the cost that increases the composite sheet of leftover bits is less than all adopting the high composite sheet of comprehensive properties, plays the effect that reduces manufacturing cost, simultaneously reasonable application the leftover bits, improved the economic value of leftover bits.

The surface layer 4 and the bottom layer 2 are both made of PC plastic layers. Or the surface layer 4 is made of a PC plastic layer, and the bottom layer 2 is made of an ABS plastic layer. The two choices are common plastic materials for the composite board, and have the advantages of impact resistance, heat resistance, low temperature resistance, chemical resistance, excellent electrical performance, easy processing and the like.

As shown in fig. 2, the paint layer 5 is disposed on the surface layer 4, the paint layer 5 covers a part of the surface layer 4, the paint layer 5 can be used for decorating the composite board with different colors, so that the composite board can be perceived by others, and the manufacturer can mark different composite boards by using the paint layers 5 with different colors, so that the composite boards can be identified conveniently. The design that the coating layer 5 only covers a part of the surface layer 4 is to embody the visual effects of the coating layer 5 and the surface layer 4 on one composite board, and the arrangement of different colors is convenient for people to find the composite board in a pile of sundries. Be provided with on the dope layer 5 and cover dope layer 5 and surface course 4 and be used for preventing the transparent plastic layer 6 of scratch, because PC plastic layer and dope layer 5 all leave the scratch easily, the setting of covering transparent plastic layer 6 has played the effect of protective dope layer 5 and PC plastic layer. The transparent plastic layer 6 is also provided with a plastic film layer 7, and the plastic film layer 7 is transparent and used for flexible packaging and has a waterproof effect.

As shown in fig. 1 and 2, the body 1 is a cuboid, three sides of the body 1 are provided with transparent glue layers 9, and the transparent glue layers 9 are coated on the three sides of the body 1. This transparent glue layer 9 is realized fixing through the coating at the side of body 1, and the setting of transparent glue layer 9 is in order to reduce the probability that body 1 stabs personnel's hand. One side of the body 1 is not provided with a transparent glue layer 9, so that other people can observe the layer structure of the body 1 conveniently.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
