Abstract
The invention discloses a kind of high added value plastic uptake sole production methods, comprising the following steps: the plastic uptake die for shoe-sole and PU die for shoe-sole of production sole shape；TPU film is fixed on plastic uptake die for shoe-sole, plastic uptake is in sole shape；The TPU film of plastics sucking moulding is put into PU die for shoe-sole；The PU foaming stock solution that 180-200 DEG C is injected into PU die for shoe-sole, foams 20-60 seconds；Stripping forming, finished product.TPU membrane is made into sole shape by plastic uptake technique by the present invention, then foam final molding, the fraction defective of product is efficiently controlled, simultaneously, it is produced by using the TPU film haveing excellent performance, so that product shoes bottom not only tearing strength and tensile strength with higher, also have the characteristics that excellent wearability, resistance to ag(e)ing, it is anti-fade, long service life.
Description
Technical field
The present invention relates to sole manufacturing field, specially a kind of high added value plastic uptake sole production method.
Background technique
China is now the first big country of world's shoemaking, there is 3 Wan Duojia of shoes manufacturing enterprise, and producing shoes per year is more than 10,000,000,000 pairs.In recent years by
In the influence of the factors such as labor cost rising, prices of raw materials rise, some warps are brought to the development of domestic shoes manufacturing enterprise
Ji pressure promotes domestic shoes manufacturing enterprise actively to find the higher material of cost performance to replace traditional footwear material, develops novel
Footwear material.Previous sole material is mostly made of solid material, in recent years, with the rapid development of shoe industry, sole material
Kind is increasingly diversified.The solid sole that gathers that the principal status of public economy is accounted in traditional shoe industry is gradually taken by emerging foamed shoe sole
Generation, but foaming sole material, there is wearing no resistance, sole abrasion is fast, causes its service life short.
Shoe body structure mainly includes sole and vamp, and the sole is divided into indsole and outsole again, and indsole generally refers to and foot
The layer structure of bottom contact, outsole generally refer to be located under indsole and as the layer structures that the shoe body bottom is contacted with road surface,
In, bottommost of the outsole because being located at shoe body, therefore the effects of need to play anti-skidding, wear-resisting, anticorrosion well.General sole includes
Shoes outsole and the PU foamed shoe sole in shoes outsole, when producing PU foamed shoe sole, PU midsole surface is easier by dirt
Dye and hydrolysis, are also easy to cause product appearance to deform, to destroy its physical property.
Summary of the invention
The purpose of the present invention is to provide a kind of high added value plastic uptake sole production methods, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the invention provides the following technical scheme: a kind of high added value plastic uptake sole production method, packet
Include following steps:
S1. the plastic uptake die for shoe-sole and PU die for shoe-sole of sole shape are made；
S2. TPU film is fixed on plastic uptake die for shoe-sole, plastic uptake is at sole shape；
S3. the TPU film of plastics sucking moulding is put into PU die for shoe-sole；
S4. PU foaming stock solution is injected into PU die for shoe-sole, is foamed 20-60 seconds；
S5. stripping forming, finished product；
Wherein, the hardness of the TPU film be 55-95A, fusing point be 130-180 DEG C, melting means be 190 DEG C of 1-10g/10min@×
2.16kg, extension elongation rate≤200%, 4 grades of yellowing-resistant, abrasion loss≤30.
Preferably, the temperature of the PU foaming stock solution is 180-200 DEG C.
Preferably, posting TPU film on the inside of the upper cover of the PU die for shoe-sole, injection PU foaming is former in PU die for shoe-sole
After liquid, upper cover is incorporated into PU die for shoe-sole.
Compared with prior art, the beneficial effects of the present invention are: TPU membrane is made into sole-shaped by plastic uptake technique by the present invention
Shape, then foam final molding, has efficiently controlled the fraction defective of product, meanwhile, come by using the TPU film haveing excellent performance
Production also has excellent wearability, ageing-resistant so that product shoes bottom not only tearing strength and tensile strength with higher
Property, anti-the features such as fading, long service life, by pasting TPU film on the inside of PU die for shoe-sole upper cover, TPU while foaming
Film overlays on the upper surface of PU foaming indsole, so that PU foaming indsole be made to be not easily susceptible to pollute.
Detailed description of the invention
Nothing.
Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with embodiment, it is clear that described reality
Applying example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is general
Logical technical staff every other embodiment obtained without making creative work belongs to what the present invention protected
Range.
High added value plastic uptake sole production method of the invention, includes the following steps:
S1. the plastic uptake die for shoe-sole and PU die for shoe-sole of sole shape are made；
S2. TPU film is fixed on plastic uptake die for shoe-sole, plastic uptake is 55-95A at sole shape, the hardness of TPU film, is melted
Point is 130-180 DEG C, and melting means is 190 DEG C × 2.16kg of 1-10g/10min@, and extension elongation rate≤200%, is worn by 4 grades of yellowing-resistant
Amount≤30；
S3. the TPU film of plastics sucking moulding is put into PU die for shoe-sole；
S4. the PU foaming stock solution that 180-200 DEG C is injected into PU die for shoe-sole, foams 20-60 seconds；
S5. stripping forming, finished product.
It is injected before PU foaming stock solution into PU die for shoe-sole, TPU film, PU is sticked on the inside of the upper cover of PU die for shoe-sole
In die for shoe-sole after injection PU foaming stock solution, upper cover is incorporated into PU die for shoe-sole, so that TPU film overlays on while foaming
The upper surface of PU foaming indsole, so that PU foaming indsole is not easily susceptible to pollute.
TPU membrane is made into sole shape by plastic uptake technique by production method of the invention, and then foam final molding, has
The fraction defective of product is controlled to effect, meanwhile, it is produced by using the TPU film haveing excellent performance, so that product shoes bottom is not only
Tearing strength and tensile strength with higher also have the characteristics that excellent wearability, resistance to ag(e)ing, prevent fading, use the longevity
Life length, by pasting TPU film on the inside of PU die for shoe-sole upper cover, TPU film overlays on the upper of PU foaming indsole while foaming
The reliability and service life of product are improved to guarantee that PU foaming indsole is not easily susceptible to pollute in surface.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
