Low-odor low-temperature-resistant synthetic rubber leather and preparation method thereof

Abstract

The invention discloses a low-odor low-temperature-resistant synthetic rubber leather. The low-odor low-temperature-resistant synthetic rubber leather comprises a base fabric layer, a hot melt adhesive layer, a synthetic rubber layer and a surface layer which are laminated in sequence; the hot melt adhesive layer is an EVA hot melt adhesive layer or an SIS adhesive layer. The synthetic rubber layer is prepared from, by weight, 70-90 parts of synthetic rubber, 10-30 parts of calcium carbonate, 0.02-0.06 part of a light stabilizer, 0.02-0.06 part of an antioxidant and 2-6 parts of a cross-linking agent. A preparation method of the synthetic rubber leather comprises the following steps of (1) preparation of a base fabric attachment adhesive; (2) compounding of the synthetic rubber layer; (3)PU film treatment; (4) treatment of a pattern removal machine. The physical properties of the synthetic rubber leather can compare favourably with those of polyvinyl chloride synthetic leather, the handfeeling of the synthetic rubber leather can compare favourably with that of polyurethane synthetic leather, and the synthetic rubber leather has the advantages of being resistant to low-temperaturebending, free of VOC and DMF and environmentally friendly.

Description

technical field [0001] The invention relates to artificial leather, in particular to a synthetic rubber leather with low odor and low temperature resistance and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the demand for leather products has increased sharply, and the grades of customers have become higher and higher. Leather has been widely used in people's various lives. The best choice of leather is real leather, but the production process of real leather seriously pollutes the environment, and the yield of leather is low in the leather processing process, the price is expensive, and the middle and low-grade leather products are unacceptable. Today, when energy conservation, environmental protection and sustainable development are advocated, people have developed imitation leather fabrics to replace animal leather, thereby avoiding harm to animals and reducing damage to the environment.

AI Technical Summary

Problems solved by technology

Ordinary polyvinyl chloride synthetic leather feels hard, has a strong smell, and plasticizers are precipitated, which cannot eliminate problems such as volatile organic compounds (VOCS). However, the production process of polyurethane synthetic leather is complicated, and the abrasion resistance, hydrolysis resistance, and production process and finished products All contain dimethylformamide (DMF) harmful substances, so there are deficiencies in environmental performance
