Description
Technical field
The present invention relates to the production technology of sole, specifically, being related to a kind of preparation method of the hard sole of wear-resisting height.
Background technology
Plastic cement is mainly made up of carbon, oxygen, hydrogen and nitrogen and other organic or inorganic elements, and finished product is solid, is being manufactured
It is the liquid of molten in journey, therefore can heat makes its fusing, plus-pressure its flowing, cooling is made its solidification, and formed each
Kind shape.Plastic cement mainly has point of thermoplasticity and thermosetting plastic, and thermoplastic plastic refers to heats still plastic plastic cement repeatedly：
Mainly there is the conventional raw material such as PE/PP/PVC/PS/ABS/PMMA/POM/PC.Thermosetting plastic refers mainly to the synthesis tree of heat hardening
Fat is obtained to obtain plastic cement, as some phenolic aldehyde plastic cement and amino plastic cement, is of little use.
Compared to rubber soles, plastic sole progresses into the visual field of people due to the characteristics of its light easy-formation, keeps away
Rubber soles are exempted from because excessively heavy caused by its density is larger the problem of.In addition, plastic sole is in normally dry environment
Physical property is very good, light easily foaming, can do the various colors of spraying, folding resistance is excellent, and the hardness of rubber is generally less than plastic cement
Material, but plastic material is compared to elastomeric material, it is slightly inferior in its wearability, exist during for manufacturing plastic sole product and use
Life-span shorter deficiency.
