Ecological type water-based synthetic leather

Abstract

The invention relates to ecological type water-based synthetic leather which comprises a dry layer, a foaming layer, a bonding layer and a base material, and is characterized in that the dry layer, the foaming layer, the bonding layer and the base material are sequentially compounded in a layered way; and the dry layer, the foaming layer and the bonding layer are made from water-based resin. The product does not change the physical properties of solvent type synthetic leather, the whole leather layer structure adopts the non-toxic, harmless, safe and environment-friendly water-based material, and all the links of the whole production process are maintained to be clean and environment-friendly, so that the ecological type water-based synthetic leather is completely environment-friendly. The ecological type water-based synthetic leather saves a great deal of organic solvent, reduces the production cost of the synthetic leather, and is in accordance with the development tendency of synthetic leather industry, thus having a wide application prospect.

Description

Technical field [0001] The invention relates to a leather, in particular to an ecological water-based synthetic leather. Background technique [0002] With the increase in human demand for leather, natural leather has long been unable to meet people's needs. With the continuous innovation of PU synthetic leather technology, synthetic leather has achieved the excellent performance of natural leather, and has greater advantages than natural leather in terms of wear resistance, low temperature performance and cost. It is foreseeable that PU synthetic leather will also be used more widely due to the needs of human renewal. [0003] my country is a major producer and consumer of synthetic leather. At present, most companies engaged in synthetic leather production use organic solvent-based resins as their main raw materials. Solvent-based resins contain 70%-80% of dimethylformamide, toluene, etc. Toxic and harmful organic solvents, these organic solvents will produce waste water, waste ...

AI Technical Summary

Problems solved by technology

[0003] my country is a big producer and consumer of synthetic leather. At present, most enterprises engaged in the production of synthetic leather use organic solvent-based resins as the main raw materials. Solvent-based resins contain 70%-80% of dimethylformamide, toluene, etc. Toxic and harmful organic solvents, these organic solvents will produce waste water, waste gas, and waste residue in many links of the production process, which pose a great threat to the health of production operators and cause serious pollution to the surrounding environment of the factory

In order to meet the national environmental protection requirements, enterprises increase the investment in equipment and personnel in the production process of waste generation for environmental protection, thus increasing the production cost of synthetic leather

Moreover, organic solvents are flammable and explosive, and there are many examples of fires and explosions in synthetic leather manufacturers.

In summary, the traditional leather industry has serious problems of high pollution, high risk, and high energy consumption.
