PVC aeration modified slipper and manufacturing method of the same

Abstract

The invention relates to a PVC air blowing modified slippers and a production method thereof. 100 parts by weight of polyvinyl chloride pellets, 65 to 75 parts by weight of plasticizer, 0.3 to 0.5 parts by weight of stabilizer, 0.3 to 0.4 parts by weight of 5 parts by weight of special anti-scorch agent for PVC blowing, 0.35-0.45 parts by weight of lubricant, 0.15-0.25 parts by weight of special dispersant for PVC air-blown slippers, 0.1-0.2 parts by weight of antioxidant, 0-1.5 parts by weight of toner It can be made into shoe sole molding raw material; after mixing in the mixing process, it becomes a molten shoe sole molding raw material under the conditions of temperature 140-200°C and pressure 40-50MPa; it is injected into the Mold cavity; after mold locking, blowing air with a pressure of 0.8-1.2 MPa into the molten shoe sole molding raw material for 2.0-3.0 seconds; molding and demoulding to obtain PVC blown modified shoe soles. It has the advantages of convenient material recycling, environmental protection, good softness of the sole, non-slip, cold resistance, wear resistance, not easy to aging, and light weight.

Description

technical field [0001] The invention relates to a PVC blown modified slipper and a manufacturing method thereof. Background technique [0002] PVC air-blown slippers are a new type of slippers. PVC products are particularly sensitive to processing temperature and are easily burnt during processing. At the same time, this new type of shoe material must add a variety of new chemical additives in the production process, so compared with traditional PVC slippers, the production requirements and technical content are higher, and the mold and production process technology are different from the conditions required by traditional PVC slippers. Many manufacturers are facing the following difficult problems in the production process: [0003] 1) The material is easy to burn and change color: if the production temperature is low, the foaming will not be good and the product will be heavy; if the production temperature is high, the material will be easy to burn and change color, and t...

AI Technical Summary

Problems solved by technology

[0003] 1) The material is easy to burn and change color: if the production temperature is low, the foaming will not be good and the product will be heavy; if the production temperature is high, the material will be easy to burn and change color, and the surface will blister;

[0004] 2) The foaming of the shoe body is uneven: the front and rear are loose and have large holes, and the foaming in the middle is not good; resulting in insufficient overall support of the shoe body;

[0005] 3) Uneven surface color: serious color difference between the front and back and the middle, and serious flow marks around the injection hole;

[0006] 4) Although the weight is light, the surface is dull, the toughness is not good, and it is not wear-resistant;

[0007] 5), high cost: no selling point in the market, not competitive enough

The PVC slippers for the above-mentioned invention patent application must add expansion agent and foaming agent, and it cannot solve the problem of uneven foaming of the cells of the shoe body, and is also not conducive to the recovery of materials.
