Description
Technical field
The present invention relates to footwear manufacturing technology field, a kind of specific system for referring to new waterproof polyurethane shoe-sole and finished shoe
Make method.
Background technique
Shoes are the necessitys with people, are the important tools that people protects foot's safety, it is well known that shoes master
It to be made of sole and vamp, current shoes manufacturing method is usually separately fabricated sole and vamp, then by sole and vamp
It is bonded together by adhesive or chemical solvent, then deburring, drying, sizing again, traditional footwear manufacturing process is complicated, work
Sequence is more, low efficiency, processing charges are high, sole and is also needed after instep formation using adhesive by being bonded together manually, in addition, leading to
It crosses in adhesive or chemical solvent adhesion process, the volatilization of adhesive composition can cause environmental pollution or even be harmful to the human body,
Not environmentally, and using adhesive or chemical solvent the sole and vamp being bonded together bond insecure, the chance easy degumming of water, shoes
Service life it is short；Now, the material for manufacturing shoes is broadly divided into rubber, polyurethane, PVC, MD, TPR, EVA etc., wherein rubber
The technology of main material as functional sole of shoe has last 100 years history, include from the natural rubber of early stage to artificial rubber SBR,
NBR, EPDM, BR, IIR, CR, FKM etc. extensive utilization to sole material；However rubber material there are heavier mass, be not easy
Degradation, gas permeability and hygroscopicity are bad, the disadvantages of easily being pierced through, in addition the complex manufacturing process of rubber is time-consuming, rim charge can not be returned
It receives, is gradually replaced by brand-new material polyurethane at present, polyurethane material is with light, wear-resisting, hardness is high, elasticity is good, resistance to
The good characteristics such as burn into environmental protection and excellent damping performance, capture rapidly footwear material market, are liked by people.
Application No. is the Chinese invention patents of CN201811108410.2, disclose a kind of production method of polyurethane shoe-sole
And can be used for urethane raw and the preparation of the production method, had according to urethane raw itself prepared by its method good
Good cementability, the solidification process in mold, itself sizing become outsole, are completed at the same time the bonding to indsole or accessory, tie
It closes securely, avoids solvent contamination caused by combining using glue；But this application, which is not accounted for, carries out water-proofing treatment to shoes,
Polyurethane-type foamed material meets water capacity facile hydrolysis, using shoes made of polyurethane material or sole, if for a long time in contact tide
Wetland face is placed in a humid environment, is easy to cause shoe body to be easy to produce and is come unglued or split, and the position come unglued or split is logical
Often between midsole and vamp, therefore in fabrication, the water-proofing treatment of shoes is extremely important, especially the waterproof of midsole
Processing is more important, and polyurethane shoes on the market do not carry out water-proofing treatment to vamp at present, at the waterproof of midsole
Reason is also only limitted to spray marine glue on the lateral wall of midsole.
