Foamed micropore layer of artificial leather for lining of PE shoes and method for preparing artificial leather by using same

Abstract

The invention discloses a foamed micropore layer of artificial leather for lining of PE shoes and a method for preparing artificial leather by using the same. The components of the foamed micropore layer comprise polyethylene, ethylene-vinyl acetate copolymer, styrene-butadiene copolymer, active calcium carbonate, azodicarbonamide, zinc oxide, white pigment, dicumyl peroxide and antioxidant. The preparation method comprises the following steps of: adding the prepared raw materials to a high-speed mixer and mixing the raw materials; conveying the mixed material to a hopper of an extruder and plasticizing the material; conveying the plasticized material to a four-roller calendar and rolling the material into a thin film; laminating the thin film on a fabric foundation in a rolling manner and trimming the thin film; winding the thin film by a winding machine to form the semi-finished product, conveying the semi-finished product to an oven and carrying out the cross-linking foaming on the semi-finished product; taking the foamed product out of the oven, embossing the foamed product on an embossing roller, cooling the foamed product and pressing down the embossing roller to obtain the artificial leather for the lining of PE shoes. By adopting the technical scheme of the invention, the artificial leather for the lining of PE shoes has the advantages of high arc stiffness, good cold resistance, high foaming ratio, vulcanization resistance and the like, and has low labor intensity, low energy consumption and short treatment period.

Description

1. Technical field: [0001] The invention relates to an artificial leather, in particular to a PE-shoe lining artificial leather foamed microporous layer and a method for preparing artificial leather by using the foamed microporous layer. 2. Background technology: [0002] Artificial leather for shoe lining is generally polyvinyl chloride PVC foamed artificial leather. The artificial leather prepared by this method has disadvantages such as low stiffness and poor cold resistance; and the raw material formula of the foamed microporous layer contains a large amount of liquid plasticizer, stable In this way, in the production process, a large amount of plasticizers and stabilizers will evaporate, causing environmental pollution and not conducive to environmental protection. Ordinary foamed polyethylene PE artificial leather can only be used in student schoolbags, etc., because this kind of artificial leather has low foaming ratio and is not resistant to vulcanization, so it cann...

Problems solved by technology

[0005] Aiming at the various shortcomings of the raw material formula of the foamed microporous layer used in artificial leather and the production process of artificial leather to a certain extent, the inventor has successfully developed a PE-shoe lining artificial leather foamed microporous layer after long-term experimental research. The raw material formula of the foamed microporous layer can be used to produce a kind of artificial leather with the advantages of high stiffness, good cold resistance, high foaming ratio, and vulcanization resistance.
