Embodiment Construction

[0022] see figure 1 , The plastic composite 100 of a preferred embodiment of the present invention includes a first plastic part 10 , an adhesive layer 30 and a second plastic part 50 sequentially formed on the first plastic part 10 .

[0023] The material of the first plastic part 10 can be polycarbonate (PC), polymethyl methacrylate (PMMA), a blend of polycarbonate (PC) and polyethylene terephthalate (PET) Any of thermoplastic resins such as polyamide (PA), acrylonitrile-styrene-butadiene copolymer resin (ABS) and polyurethane (PU). Preferably, glass fibers are added to the thermoplastic resin. The thickness of the first plastic part 10 is 0.6-1mm.

[0024] The adhesive layer 30 is colorless and transparent, and is formed on the first plastic part 10 by spraying. The adhesive layer 30 is mainly composed of aminosilane coupling agent. In this example, the main component of the aminosilane coupling agent is γ-aminopropyltriethoxysilane.

[0025] The second plastic part 50...

Abstract

The invention relates to a plastic composite body comprises a first plastic part and a second plastic part laminated on the first plastic part. The material of the first plastic part is thermoplastic resin, and the material of the second plastic part is thermosetting resin. The plastic composite body also comprises an adhesion layer arranged between the first plastic part and the second plastic part. The adhesion layer is mainly composed of an amino silane coupling agent. The invention also provides a manufacturing method of the plastic composite body.

Description

technical field [0001] The invention relates to a plastic compound and its manufacturing method. Background technique [0002] In the prior art, a plastic composite body with an insert is formed by the following method: first, a first plastic part is provided, and the insert is consolidated on the surface of the first plastic part; then, the first plastic part is placed on a Injection mold; After that, inject molten thermoplastic resin into the mold under high temperature and high pressure conditions, and combine a transparent or translucent second plastic part on the surface of the first plastic part after cooling the mold. The pattern formed on the surface of the first plastic part can be seen through the second plastic part, and at the same time, the pattern can be prevented from being eroded and worn by the outside world. However, in the above-mentioned high temperature and high pressure injection molding process, the relatively large scouring force is likely to damage ...
