Description
Technical field
The present invention relates to a kind of polychrome shock-absorbing soles and preparation method thereof, belong to footwear material technical field.
Background technique
Requirement with consumer to product shoes is continuously improved, and the shoe sole article of several colors and hardness has been on the market at present
It is difficult to meet customer requirement, consumer needs there are more colors in different parts on sole.Existing production preparation side
Method are as follows: first by different colours, the EVA material of different hardness is foamed into sheet material respectively, rushes further according to the shape at different colours position
It determines and, by deep processing after bonding combination, then carry out secondary frothing forming to be made.Existing preparation method exists as follows
Defect and deficiency: 1, EVA material first will carry out sheet material foaming by different colours and hardness respectively, then be punched by required shape, this
Sample operation, causes board utilization rate to increase, while causing a large amount of wastes of EVA material；2, bonding combination deep processing is will to be punched
Good shape fits together according to required color in deep processing, and bonding combination mainly takes binder to be allowed to viscous as medium
It is solidified as a whole required to achieve the effect that, results in increasing a large amount of labour cost in this way, increase slice applying machine bench and glue
Raw material increases production cost, meanwhile, cause biggish environment to influence, and degree of adhesion is inadequate, product by different temperatures,
Different liquids corrode and the influence of reasons such as different road surfaces and go bad, junction separation dislocation or damage seriously affect product
Matter.
For this purpose, in 103817964 A of application publication number CN, it is entitled " a kind of preparation method of EVA polychrome sole "
Chinese invention patent application in, disclose a kind of preparation method of EVA polychrome sole, which is characterized in that including as follows
Step:
(1) sampled and be opened according to colour pattern: as needed, the shape of different colours corresponding position is taken out to shoemaking original pattern product
Shape opens injection mold processed with the same multiplying power of foaming mould, each color corresponding position opens injection mold processed；The injection mould
Cooling device is equipped in tool；
(2) injection molding: respectively sequentially by different colours, different hardness but the consistent EVA particulate composition of expansion ratio
By injection device heating dissolution after, be injected separately into the injection mold of corresponding color, by cooling device to injection mold into
Row cooling, using the EVA material fast shaping in injection mold at each color prefabrication；
(3) injection-molded item foams: each color prefabrication being combined into complete sole, then smooth implantation high temperature foaming mould
Interior crosslinked foaming obtains semi-finished product crude green body；
(4) semi-finished product are processed: semi-finished product crude green body being polished into semi-finished product by surface, keeps each color junction linearly
Subject to state；
(5) be pressed and molded to obtain finished product: by the secondary mold of the smooth merging of the semi-finished product after trimming, hot briquetting, after it is cold again
But it is formed, obtains EVA polychrome sole.
The damping effect of the sole manufactured using the above scheme, the sole is poor, and it is thick that each color products are foamed into semi-finished product
When base, each color products are difficult to fitly align, and need that more time is spent to carry out surface polishing, affect labor productivity.
In consideration of it, inventor furthers investigate the above problem, there is this case generation then.
