Abstract
Rollon preparation method without solvent dual-component polyurethane synthetic leather disclosed by the invention, it comprises the steps: 1) raw material preparation step; 2) it is coated with cortex step; 3) the first drying step; 4) upper base material step; 5) dry solidification step; 6) rolling step. Manufacture craft of the present invention is simple, no matter is which kind of working method all can directly complete in streamline previous step, and energy consumption is low, with low cost.
Description
Technical field
The invention belongs to Synthetic Leather technical field, relate generally to a kind of preparation method and the equipment that have employed rollon solvent-free double-component polyurethane synthetic leather, and the synthetic leather that the method is produced.
Background technology
Leather industry is the conventional industries that China has comprehensive advantage. At present, the leather output of China accounts for more than the 20% of Gross World Product.
Natural leather has excellent natural characteristic, is commonly used by people for industry-by-industry, but along with people are to the multiplication of leather demand, limited natural leather can not be met the need of market. The appearance of synthetic leather, compensate for the deficiency of this respect just. The output of China's synthetic leather, always in increasing progressively state, has become the big producing country of world's synthetic leather, more has flourish trend under big economic environment.
Synthetic Leather is the macromolecular material that a class has property, through the research and development of twenties years, present Synthetic Leather has had the wear-resisting of excellence, folding, solvent resistant, oil resistant, the mechanical property such as ageing-resistant, and there is the feel of the excellence the same with natural leather, surface luster is soft, and adhesive property excellent between base material, also possesses ventilative, can wash simultaneously, easy to process, the advantage such as cheap, is the ideal substitute of natural leather, is widely used in footwear, suitcase, clothes, sofa, automotive trim, furniture etc.
What widely use in existing market is the oiliness synthetic leather having solvent, this leather pollutes big, easily residual, many enterprises once made the transition production Waterborne synthetic leather for this reason, although Waterborne synthetic leather ecological, environmental protective, but still organic solvent need to be mixed, and stability is also not as oiliness synthetic leather, turn to for this reason and produced the synthetic leather without solvent, without organic solvent in starting material, mean that volatile organic compounds (VOC) is almost equal to zero, reach the effect in Control pollution source, also eliminate the exhaust emission to environment, realize cleaner production, without that kind of pungent taste in the past in workshop, air has been got well a lot, also protect the health of operation workman simultaneously. therefore, producing synthetic leather with solventfree resin, it can be said that " omnidistance no pollution ", if promoting this technology, this pollution industry in the past of synthetic leather will thoroughly move towards environmental protection.
No-solvent polyurethane synthetic leather also has excellent process based prediction model simultaneously, and such as ventilative and water vapour permeability, folding resistance, wear resistance, ageing resistance, excellent draws high intensity and elongation. Although without solvent PU synthetic leather production technique or one piece " experiment field ", just coming out of from laboratory, but market degree of recognition is very high, especially the enterprise such as the case and bag of the Western European countries, furniture, leatherware, is all seeking free of contamination leather material. So, have more good market outlook without solvent PU synthetic leather.
