Description

A kind of technique that the cold foaming of PU makes sole
Technical field
The invention belongs to the techniques that the cold foaming of sole manufacturing field more particularly to a kind of PU makes sole.
Background technology
China is now the first big country of world's shoemaking, there is family more than 30,000 of shoes manufacturing enterprise, and it is more than 10,000,000,000 pairs to produce shoes per year.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, exploitation novel Footwear material.Previous material for sole of shoe is mostly made of solid material, in recent years, with the rapid development of shoe industry, material for sole of shoe 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.
General sole includes shoes outsole and the PU foamed shoe soles on shoes outsole, when producing PU foamed shoe soles, PU shoes Middle bottom surface is easier to be contaminated and hydrolyze, and is also easy to cause product appearance deformation, to destroy its physical property, in order to prevent Above several undesirable elements, need to add one layer of TPU film in appearance in PU foameds, can play and keep the original physical property of sole and outer The effect of sight, in the prior art TPU film be put into PU molds, by with after vacuum suction moulding, injecting PU foaming stock solutions, draft Molding, this mode is directly placed into PU molds with TPU membrane, vacuum forming, the PU foamed shoe soles of production, side of the sole, periphery It is random with the ridge design and corner portion shape of bottom and without three-dimensional sense, also it is easy to cause because of the resilience of TPU film Product shrink modification, caused by the turned-out equal modifications phenomenon of sole.
Invention content
It is an object of the present invention to a kind of technique of the cold foaming making soles of PU has been overcome the deficiencies of the prior art and provide, PU foamed shoe sole decorative patterns prepared by this method are clear, and pattern is true to nature, and the shape of sole is identical as mold.
In order to solve the above technical problems, the technical scheme is that：A kind of cold foaming of PU makes the technique of sole, special Sign is that the technique includes the following steps：
After step 1, swage or resin film go back to factory, jetting plastic plate is loaded onto swage or resin film die for lower cover without adding Temperature, without spraying mould release；
Step 2 uses TPU film plastic uptake shoe mould plastic uptake at sole shape, and perfusion front mold upper cover sticks TPU membrane, Molding TPU film is put into PU die for shoe-sole；It may be cloth；
Step 3, using the cold bottler placers of PU, PU foaming stock solutions are injected into PU die for shoe-sole；
Step 4, the padded 10-20cm of mold half sole；
Step 5, open time 4 minutes to 4 points and 30 seconds；Stripping forming, you can obtain the sole of finished product.
Further, in above-mentioned manufacture craft, the emulsification times 7-15s of the PU foaming stock solutions；Expansion density 0.1- 0.2；Hardness 15-35 is spent.Further, the emulsification times 9-10s of the PU foaming stock solutions；Expansion density 0.12-0.14； Hardness 23-25 is spent.
Further, in above-mentioned manufacture craft, the step 3 is that TPU film is fixed on plastic uptake shoe mould, and checks Position shape is correct, directly molding, blow molding, is demoulded after 2-6 minutes cooling.
Further, in above-mentioned manufacture craft, the thickness of the TPU film is 0.1-0.7mm.
Further, in above-mentioned manufacture craft, the step 4 is 60-100 DEG C of PU foaming stock solution of injection, and foaming is cold But it is demoulded after 10-15 minutes.
Further, in above-mentioned manufacture craft, the cloth is fixed on template, then pours into PU and is foamed into die cavity Type.
On the other hand, the cold foaming of PU of the present invention makes sole and consists of the following compositions, including：40-50 parts of PU, Maleic anhydride is grafted 18-26 parts of EVA, 20-30 parts of chlorinated polyether, 15-25 parts of polydicyclopentadiene, 9,10- dihydroxystearic acids 4-8 parts, 7-14 parts of tetrahydrofurfuryl oleate, 2-4 parts of diisopropyl azodiformate, 1-3 parts of p-toluene sulfonylsemicarbazide, oxygen It is strong to change 1-2 parts of zinc, 0.5-1 parts of borax, 3-6 parts of magnesium oleate, 2-3 parts of cumyl peroxide, 5-10 parts of tricresyl phosphate, magnesium 16-22 parts of powder, 12-18 parts of aquadag powder, 5-10 parts of nano boric acid zirconium.
Further, the cold foaming of the PU makes sole and consists of the following compositions, including：PU45 parts, maleic anhydride connects EVA20 parts of branch, 25 parts of chlorinated polyether, 20 parts of polydicyclopentadiene, 6 parts of 9,10- dihydroxystearic acids, tetrahydrofurfuryl oleate 10 parts, 2-4 parts of diisopropyl azodiformate, 1-3 parts of p-toluene sulfonylsemicarbazide, 1-2 parts of zinc oxide, 0.5-1 parts of borax, oil Sour magnesium 3-6 parts, 2-3 parts of cumyl peroxide, 5-10 parts of tricresyl phosphate, magnesium is powder 16-22 parts strong, aquadag powder 12- 18 parts, 5-10 parts of nano boric acid zirconium.
Beneficial effects of the present invention：After the present invention first uses TPU plastics sucking mouldings, the side of injection foamed material in PU molds is placed into Formula, first plastics sucking moulding, before also not injecting TPU foamed materials, you can the fraction defective of 100% control product (can control before production It is bad)；By plastics sucking moulding, modification problem is very little, and yields is 95% or more；In the completed state of faceted portions, Any type shape, any weight all can plastics sucking mouldings；The especially higher formed product state of keel, the TPU membrane of any thickness It inhales and all can be used, and the thickness inhaled is uniform, it is not fragile.Foaming sole material produced by the present invention not only has higher tearing Intensity and tensile strength also have excellent wearability, resistance to ag(e)ing, water resistance and corrosion resistance, service life long.
