Description
Technical field
The present invention relates to plastic production technical field, in particular to a kind of composite plastic system
Product and production method thereof.
Background technology
The existing surface figuratum composite plastic product of band is usually by plastic forms, is compounded in plastics
The figuratum plastic sheeting of band on body surface is composited.Composite construction has two ways, Yi Zhongshi
Being combined by adhesive, so, pattern just can be arranged between plastic forms and plastic sheeting, so,
Pattern just can be protected by the plastic sheeting on surface, this kind of mode, owing to needs use adhesive,
And adhesive at high temperature can lose adhesive effect, therefore, compound tense can only be the plastics in molding
Physically carry out, and can not first carry out on the plastic forms of tabular, then, by the shape of thermal deformation
Formula becomes the composite plastic product that shape is changeable；Another kind is to form melting layer on plastic forms surface,
Then utilizing melting layer to be adhesively fixed by compound plastic sheeting in the above, this kind of mode is adopted at present
Plastic forms, plastic sheeting be all the plastic material of same nature, and these plastic materials are all
The material of light transmission difference, the pattern being easily destroyed on plastic sheeting due to melting layer, and thin-film material
Being all the material of light transmission difference, therefore, pattern is all provided in the plastic sheeting of composite plastic product
Outer surface, although, this kind of mode can first be carried out on the plastic forms of tabular, then, is become by heat
The form of shape becomes the composite plastic product that shape is changeable, but, outside being directly exposed at due to pattern,
So, pattern is just highly susceptible to the destruction in the external world, and, the third dimension of pattern is poor.
For solving above-mentioned technical problem, the patent of invention of Application No. CN201010224779.7 discloses
A kind of composite plastic product and production method thereof, including plastic forms, be compounded in plastic forms surface
Carrying figuratum TPU plastic sheeting, pattern is positioned between plastic forms, TPU plastic sheeting, plastics shape
Being combined by plastic forms melt surface layer between body, TPU plastic sheeting, TPU plastics are thin
The hot recombination process of film is by pre-to the plastic basic unit plate of firm molding and the inner surface being positioned on plastic plate face
Arrange figuratum TPU plastic sheeting to run through lower compression roller together and be pressed into as composite plastic plate.
Summary of the invention
Technical problem solved by the invention: the shape of plastic forms surface imperfection, causes pressing up and down
Roller is difficult to that inner surface pre-sets figuratum TPU plastic sheeting and is pressed together on the plastic forms of firm molding
Surface.
For solving above-mentioned technical problem, the present invention provides following technical scheme: a kind of composite plastic product,
Including plastic forms, the TPU plastic sheeting that is compounded in plastic forms surface；Described TPU plastic sheeting
It is embedded in the melting layer on plastic forms surface.
TPU plastic sheeting has high ductibility, high tear resistance, anti-piercing through property, wearability, printing opacity
Property the characteristic such as good, use plastic forms melting layer and TPU plastic sheeting complex technique, specifically, TPU
Plastic sheeting is embedded in plastic forms melting layer, in this manner it is possible to first make plastic forms, TPU
Plastic sheeting composite board, is the most at high temperature required variously-shaped by mould molding.
Technique scheme of the present invention, even if plastic forms surface configuration is irregular, it is possible to moulded by TPU
Material Film laminated is on plastic forms surface, to solve in prior art because plastic forms surface configuration is not advised
Then cause lower compression roller to be difficult to TPU plastic sheeting being pressed together on the technology on plastic forms surface being asked
Topic.
As the present invention a kind of explanation to plastic forms, the material of described plastic forms be PP, PC,
The one of which of PE, ABS, or, described plastic forms is the synthetic material of PA and ABS, or,
Described plastic forms is the synthetic material of PC and ABS.Described plastic forms is lid shape or casing shape.
Described TPU plastic sheeting is with pattern, and pattern is positioned between plastic forms, TPU plastic sheeting.
The positive and negative of described plastic forms is all compounded with inner surface band figuratum TPU plastic sheeting.
Owing to the present invention uses plastic forms melting layer and TPU plastic sheeting complex technique, high-temperature molding
Time, composite bed also will not separate and come off, it is ensured that the quality of product, pattern is positioned at TPU plastic sheeting
In, make pattern be subject to good protection, meanwhile, be embedded in the TPU in plastic forms melt surface layer
Plastic sheeting, under the effect of its light transmission, makes pattern have good third dimension, makes pattern show
More attractive truly.
The processing method of a kind of composite plastic product of the present invention includes the thermoforming of plastic basic unit plate
Journey, the hot recombination process of TPU plastic sheeting, heating and mould pressing process.Wherein, described plastics
The thermoforming process of basal plate is will to inject mould after plastic raw materials high-temperature fusion under setting squeeze pressure
The process of moulding plastics basal plate；The hot recombination process of described TPU plastic sheeting is will to be attached to mould
The process that TPU plastic sheeting on inner surface and the plastic basic unit plate in mould are combined, described TPU moulds
Material thin film was attached on mould inner surface before melted plastic raw materials injects mould, and TPU plastics are thin
The inner surface of film pre-sets pattern；Described heating and mould pressing process are to be suppressed by heating and mould
Mode by above-mentioned by the composite plastic being composited with plastic basic unit plate with figuratum TPU plastic sheeting
Flitch makes casing shape or the composite plastic product of lid shape.
Owing to there is the temperature that comparison is high when melted plastic raw materials injects mould, it is attached to mould in advance
TPU plastic sheeting on medial wall is surrounded by the plastic basic unit plate surface in molten condition, after cooling,
TPU plastic sheeting is embedded in the melting layer on plastic basic unit plate surface.In order to obtain answering of various shape
Close plastic, by above-mentioned by carrying figuratum TPU plastics thin by the way of heating and mould compacting
