A kind of synthetic leather for swivel chair and preparation method thereof

Abstract

The invention discloses synthetic leather for a swivel chair. The synthetic leather comprises a bottom layer and surface layers attached to the two sides of the bottom layer. The surface layers comprise the following components of, by weight, 100 parts of PVC resin, 50-60 parts of a plasticizer, 20-30 parts of aramid fibers, 20-30 parts of silk fibers and 5-10 parts of a foaming agent. The bottom layer comprises the following components of, by weight, 100 parts of PVC resin, 30-40 parts of calcium carbonate, 5-10 parts of a stabilizer and 5-10 parts of polytetrafluoroethylene. A preparation method comprises the following steps of (1) preparation of the bottom layer, (2) preparation of the surface layers and (3) hot pressing compounding. According to the synthetic leather, creativity is high, characteristics are distinct, gas permeability and abrasion resistance are improved overall, and thus the bottom layer and the surface layers are not liable to corrosion and division in a high-temperature humid environment.

Description

technical field [0001] The invention relates to synthetic leather for swivel chairs and a preparation method thereof. Background technique [0002] With the continuous development of society, people's living standards are improving day by day, and people's requirements for living environment are also increasing day by day. At present, synthetic leather for swivel chairs is not resistant to moisture, light, and easy to break, and it is difficult to achieve high-end decorative effects. For natural leather, due to the constraints of natural conditions and the gradual strengthening of the awareness of animal protection around the world, natural leather is decreasing year by year. At present, the synthetic leather for swivel chairs developed on the market generally includes a surface layer and a bottom layer. The surface layer is generally made by mixing PVC resin with various modifiers, and the bottom layer is generally a fiber layer. However, such synthetic leather is breathab...

AI Technical Summary

Problems solved by technology

At present, the synthetic leather for swivel chairs developed on the market generally includes a surface layer and a bottom layer. The surface layer is generally made by mixing PVC resin with various modifiers, and the bottom layer is generally a fiber layer. However, such synthetic leather is breathable. Not good, poor wear resistance, poor anti-corrosion and acid-proof performance, not soft to the touch, and the bottom layer and surface layer are easily corroded and split in high temperature and humid environment
