Abstract

A surface decoration technique for the composite material includes such step as putting a printed film on a composite plate, loading them in a die set, hot die pressing, and opening the die set.

Description

The surface decoration technique of composite
Technical field
The present invention relates to a kind of surface decoration technique, particularly relate to a kind of surface decoration technique of composite.
Background technology
The plastic casing of mobile electron commodity is because its inner precise electronic assembly that needs protection; take into account user's mobile convenience again; therefore need the light and high-intensity plastic raw materials of service property (quality) to make, composite is wherein a kind of plastics commonly used and strengthens raw material.Composite is that short fiber or long stapled reinforced plastics material are added in a kind of utilization in plastic raw materials.
Use composite to make the work flow of the plastic casing of mobile electron commodity, it is generally earlier plastic raw materials is mixed with fiber to form composite board, is cut into suitable size then.Then, smooth sheet material is placed in the mould, under the heating pressurized state, carries out the mold pressing step, allow sheet material form required three-dimensional shape.Then, open mould and take out finished product.
Owing in the process of mixed plastic raw material and fiber, can add organic solvent both can be mixed.If mixing is inhomogeneous, in follow-up mold pressing step, easily form bubble, make finished surface form defective.Therefore need again to be polished after the processing in the surface of finished product, just can spray paint, finish final products.Or the processing of not polishing directly increases the blemish that the thickness that sprays paint is covered product.
Yet above-mentioned polishing procedure of processing can reduce the output of product, increases the unit price of product.In addition, the dust that polishing processing is produced easily allows the operator suck and causes employment injuries.The spray paint practice of thickness of above-mentioned increase not only can not solve the problem of blemish fully, also can reduce the qualification rate of product.
Summary of the invention
Therefore one of purpose of the present invention is exactly the surface decoration technique that is to provide a kind of composite, can solve the blemish problem of composite effectively.
According to above-mentioned and other purpose of the present invention, a kind of surface decoration technique of composite is proposed.At first, form composite board earlier, then it is cut into suitable size with required three-dimensional shape.In addition, form plastic sheeting, again it is cut into suitable size with required pattern and required three-dimensional shape.Above-mentioned composite board and plastic sheeting are put into the mould of die sinking, allow plastic sheeting be positioned on the composite board.Mould is shut, and molded composite material sheet material and plastic sheeting allow composite board combine together moulding with plastic sheeting.The composite finished product with incrustation is taken out in die sinking then.
According to a preferred embodiment of the present invention, above-mentioned mold pressing step is preferably only heating and does not pressurize.And the heating means of being implemented in the mold pressing step are preferably and utilize infrared ray to heat, and composite board can be softened get final product.
According to above-mentioned, print the surface decoration material of the plastic sheeting of pattern owing to use as composite finished product, so can cover the blemish of composite finished product fully, can not produce existing problem again.
Description of drawings
Fig. 1 is the processing and manufacturing flow chart of a kind of in-mold decoration of the composite of preferred embodiment of the present invention.
The specific embodiment
As mentioned above, the invention provides a kind of surface decoration technique of composite, can solve the blemish problem of composite effectively, do not have the puzzlement of prior art again.Below will cooperate preferred embodiment to be described in detail.
In-mold decoration (in-mold decoration; IMD) be a kind of mode of utilizing colored printing, on clear films, do colored printing.Afterwards, good film carries out steps such as hot-forming and die-cut to allow colored printing.At last, put into mould, carry out the injection molding step, allow colorful film and plastic tie synthesis type, can produce plastic product with colored appearance attractive in appearance.Many plastic products that can't spray paint and handle with printing often use the technology of in-mold decoration to decorate its appearance.
The present invention after above-mentioned decoration technique inside mold is done suitably to revise, is applied on the surface decoration technique of composite, to overcome and to solve the technical problem of the incrustation of existing composite.Please refer to Fig. 1, it illustrates the processing and manufacturing flow chart according to a kind of in-mold decoration of the composite of preferred embodiment of the present invention.In Fig. 1, select suitable plastic raw materials and fiber (step 110) earlier, after both are evenly mixed, carry out the compression molding step, form the composite board (step 120) of required three-dimensional shape.Employed composite in the mobile electron commodity, its plastic raw materials can be selected polyethylene terephthalate (polyethylene terephthalate usually; PET) or polymethyl methacrylate (polymethyl methacrylate; And fiber can be selected carbon fiber or glass fibre usually PMMA).
Then, select suitable plastic film (step 130), utilize the manufacture craft of spraying paint to carry out colored printing (step 140) in the above.Utilize hot-forming manufacture craft again, form the colored plastic film (step 150) of required three-dimensional shape.The three-dimensional shape of colored plastic film is consistent with the three-dimensional shape of above-mentioned composite board.
Then, under die opening state, the colored plastic film stack is combined on the composite board, puts into the mould (step 160) of composite.To mold heated, be preferably and use infrared ray mold heated, make composite board softening.So, composite board and colored plastic film just can combine and moulding (step 170) in same mould.It should be noted that above-mentioned compression molding step 170, be preferably and utilize cold mould, and only utilize infrared ray to come heating mould, but mould is not applied high pressure.At last, after mould opened, can take out composite finished product (step 180) with coloured surface outward appearance.From the above, preferred embodiment of the present invention will have now injection molding decoration technique inside mold (IMD) correct locate as follows: (1) the present invention does not apply high pressure to mould, but existing be that mould is applied high pressure; (2) the present invention omits existing injection step, but existing need have injection step.
From above-mentioned preferred embodiment as can be known, the present invention is directed to the characteristic of composite, the decoration technique inside mold that existing script is applied in injection molding is improved, and is applied on the composite then.This measure not only allows composite finished product have surface attractive in appearance again best in quality, can also omit the polishing processing and the work of spraying paint of existing composite.Therefore use the qualification rate that the present invention not only can improve composite finished product, also can improve its productive rate.
Though disclosed the present invention in conjunction with an above preferred embodiment; yet it is not in order to limiting the present invention, anyly is familiar with this operator, without departing from the spirit and scope of the present invention; can be used for a variety of modifications and variations, so protection scope of the present invention should be with being as the criterion that claim was defined.
