Abstract
The present invention relates to a producing method of synthetic leather. Materials are output by a determined number of metering output devices, wherein at least one charging basket is filled with isoleucine salt polymers, and the other charging basket is filled with hydroxy compounds; the materials inside the charging baskets are all liquid and are metered and output according to an isomolar proportion. The liquid materials are led in a material spraying and mixing device to generate an instant reaction for forming fluid mixed liquid, and the mixed liquid is poured out by a vertical flow mode. Two output devices for base cloth are respectively arranged on both sides of the lower part of the material spraying and mixing device and used for gradually outputting the base cloth which is previously selected and coiled, in the direction towards the center of the bottom of the material spraying and mixing device. The mixed liquid is positioned in the intermediate position of two pieces of base cloth. As solvents do not use, washing equipment and exhaust-gas treating equipment do not need, and the present invention has the advantage of no air pollution and no pollution of water source and has the efficiency of saving consumption of equipment and energy sources, saving the managing expense of labor, etc.
Description
Technical field
The present invention relates to synthetic skin, be meant the manufacture method of synthetic skin especially, is after various materials is mixed through shooting material, to be poured on the base cloth, to form synthetic skin, exempts solvent, water, the pollution of air and huge machinery equipment that conventional process produced.
Background technology
The manufacture method of traditional artificial synthetic skin, normally various raw materials and solvent bearing are in one or more dipping tanks, base cloth is guided, make its impregnation through material in this dipping tank, this base cloth is introduced in the tank, its surperficial gel is solidified, again base cloth is used electric heating drying equipment to give dried, to form synthetic skin.Its major defect is:
1, in the manufacture process of traditional synthetic skin, used a large amount of solvents, can cause serious environmental to pollute, for example the synthetic skin of wet type uses in the solvent and contains dimethyl formamide (Dimethyl Formamide is called for short DMF), cause poisoning as knowing from experience via skin absorbs or by lung suction people, its poison control centre for being managed by Environmental Protection Administration, factory must be provided with the equipment of gas collection and exhaust-gas treatment according to the rules, factory and government also must be at any time monitoring and write down its processing procedure, so the processing of its waste gas and waste water is quite wasted time and energy, careless slightly, promptly can cause serious pollution;
2 and its processing procedure in use electric heating drying equipment, also can expend the manpower of considerable electric power and management.
The manufacture process of the synthetic skin of another kind of dry type is to utilize resin-coated method, coat on the release liners, drying, go up stick with paste after, fit with base cloth again and dry.Its major defect is:
1, because it has used butanone (methyl ethyl ketone is called for short MEK), cause the acute toxic hepatitis of human body, and dimethylbenzene (Xyelne) has highly combustibility, can be lighted by heat, spark or flame easily, very easily produce fire, all can pollute air, water, and it also uses electric heating drying equipment, can expend considerable electric power and administrative expenses.
In addition, the manufacturing equipment of the synthetic skin of above-mentioned tradition all can't utilize its original machinery equipment with foamed plastic, and can not directly import and do continuous processing in its processing procedure.
Summary of the invention
At above-mentioned defective, the inventor is through detailed thinking, and the long-pending research and development experience of being engaged in Related product for many years, creates technical scheme of the present invention finally.
Main purpose of the present invention provides a kind of manufacture method of synthetic skin, because it does not use solvent,, obtain no air and pollution of waterhead so the equipment of washing and exhaust-gas treatment must not arranged, reach the consumption of the saving equipment and the energy, and reduce the purpose of manpower management expense.
Secondary objective of the present invention provides a kind of manufacture method of synthetic skin, and it is provided with foam device, can use when needed, to do continuous processing in its processing procedure of direct importing, makes the purpose of the synthetic skin with foaming body.
The object of the present invention is achieved like this: a kind of manufacture method of synthetic skin is characterized in that: it comprises the following step:
