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.

Abstract

The invention relates to a PVC air-blowing modified slipper and making method. The forming raw materials for shoe bottom are formulated with 100 portion of polyvinyl chloride granules, 65 to 75 portion of plasticizers, 0.3 to 0.5 portion of stabilizing agents, 0.3 to 0.4 portion of PVC special scorch retarders for air blowing, 0.35 to 0.45 portion of lubricants, 0.15 to 0.25 portion of PVC special dispersants for air-blowing slipper, 0.1 to 0.2 portion of antioxidants and 0 to 1.5 portion of toners. The forming raw materials are mixed uniformly after going through the working procedure of stirring the materials and are made into the peptized forming raw materials for shoe bottom under the conditions that the temperature ranges from 140 to 200 DEG C and the pressure ranges from 40 to 50MPa; the forming raw materials are injected into a die cavity under the conditions that the pressure ranges from 30 to 40MPa and the temperature ranges from 175 to 185 DEG C; after the die is locked, the air is blown into the peptized forming raw materials for shoe bottom and the pressure of the air ranges from 0.8 to 1.2MPa and the blowing time ranges from 2.0 to 3.0s; after the forming and demolding are carried out, the PVC air-blowing modified slipper is obtained. The invention has the advantages of being convenient for recycling the materials, environmental protection, slippage prevention, coldness resistance, abrasion resistance, lightness and convenience. The shoe bottom has good pliability and the shoe is uneasy to be aged.

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...
