Description

Utilize the putamina goods of PC film combined plastic forming and convertible decorative pattern color and luster

Technical field

The utility model provides a kind of plastic foil shell product, refers to utilize the putamina goods of PC film combined plastic forming and convertible decorative pattern color and luster especially.

Background technology

Tradition " method of thick film high-pressure molding and goods ", it is mainly: a kind of high-pressure molding method applicable to thick film processing, comprising: A. settles a thermoplastic diaphragm on a carriage; B. this thermoplastic film is adopted the surface heating; And C, utilize the thermoplastic diaphragm after this carriage will heat to be positioned on the mould, apply gases at high pressure and force the thermoplastic diaphragm to overlay and moulding on the surface of mould.The gas pressure of this method can exceed 50Kg/cm ²More than, considerably beyond an atmospheric pressure (1Kg/cm of traditional vacuum moulding ²) and the limit of working ability, the surface detail and the crest line of finished product will be more clear.Utilize above-mentioned steps, can produce the casing of various electronic products or electrical home appliances; For example, earlier in a transparent or semitransparent thermoplastic diaphragm or inner face stamp trade mark or decorative pattern, make it to take shape in inner face with above-mentioned high-pressure molding method again, then trade mark on the finished product or decorative pattern will be subjected to the thick film protection and can not lost or strike off by mill.Needing product intensity or special inner face when design especially, this finished product still can utilize and insert the inner face that the plastic cement injection method that penetrates forms enhancement Layer or institute's palpus, the conventional procedures of saving after the moulding wire mark again or spraying paint.

The method of above-mentioned this thick film high-pressure molding and goods, it must use carriage and gases at high pressure on making, and does not want to take the trouble slightly in the making.

The method of above-mentioned this thick film high-pressure molding and goods, the housing of mask decorative pattern in it can only be made, and, then lose the original meaning of its thick film protection for the surperficial housing that forms special texture or sense of touch of hope, it also can't make the product of described tool texture and sense of touch.

Therefore, at the existing problem points of above-mentioned known configurations, how to develop a kind of innovation structure that has more desirable practicality, the ardent hope of real consumer institute also is that relevant dealer must make great efforts target and the direction that research and development break through.

In view of this, the creator this in manufacturing development and the design experiences of being engaged in Related product for many years, at above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicality.

Summary of the invention

The utility model purpose is, the putamina goods of a kind of PC of utilization film combined plastic forming and convertible decorative pattern color and luster are provided, and to overcome the defective of above-mentioned traditional structure, obtains having the putamina of lines color.

The technical characterstic of dealing with problems:

A kind of putamina goods that utilize PC film combined plastic forming and convertible decorative pattern color and luster is characterized in that, include:

One has the PU resin bed of decorative pattern and color and luster, and this PU (Polyurethane) resin bed is positioned at the outermost layer of putamina, and is the PU adhesion agent layer within this PU resin bed, is the PC plate in the PU adhesion agent layer, is ABS or PC layer in the PC plate.

Wherein, also be provided with PU adhesion agent layer, wet-type PU resin bed between this PU resin bed and PU adhesion agent layer.

Wherein, also be provided with the base material binder course of PU adhesion agent layer, wet-type PU resin and nylon loop, looped fabric or adhesive-bonded fabric between this PU resin bed and PU adhesion agent layer.

In view of the above, this decorative pattern and color all are presented on the appearance of putamina, reach the effect of decorative pattern color and luster conversion.

The effect of contrast prior art:

One, prior art utilizes mould inside rag road, when having the putamina of lines with ejection formation again, if amount is less and die sinking will raise the cost, and the different moulds of lines different needs, special grains also is difficult to make mould, quite a lot ofly raises the cost again so limit.The utility model then need not the rag road, and because of the PU film has lines, direct heat is pressed into different shape again, and is with regard to plastic putamina with lines color, comparatively practical.

Two, prior art utilizes carriage to cooperate the gases at high pressure blowing, and the trade mark or the pattern of its printing come off quite easily, so make quite trouble, and for preventing that trade mark or pattern from coming off, it can only be printed on the centre or the inner face of thick film again, the people can't be run into avoiding come off, but if make product with sense of touch, the method necessarily be can not make.And the utility model utilization is combined with the PC lamina membranacea PU resin face heating of PU wet type film, and in mould, inject ABS or PC, and combine with the PC face of the PC lamina membranacea that is combined with PU wet type film, be cooled to putamina, its lines color is on the surface, removes the tool visual sense of beauty and also has a touch feeling.

The technology that relevant the utility model adopted, means and effect thereof after lifting a preferred embodiment now and cooperating graphic being described in more detail in, are believed the above-mentioned purpose of the utility model, structure and feature, when can by one deeply and concrete understanding.
