Abstract

The invention discloses a preparation method of an environment-friendly silica gel synthetic leather. The steps include: preparing a first slurry, coating the first slurry on a release paper, drying to form a surface adhesive layer, and repeating the process for the surface adhesive layer three times Alternate treatment of hot dipping and hot pressing, and evenly cover a layer of nano-silica filler on the surface of the surface adhesive layer before each hot pressing; prepare the second slurry, coat the first slurry on the release paper and bake Dry to form a primer layer, and steam the primer layer; select a base cloth, and sequentially transfer the treated primer layer and surface rubber layer to the base cloth through hot pressing and lamination and separation of paper leather to obtain environmentally friendly silica gel Synthetic Leather. In the present invention, through gradient hot dipping and hot pressing treatment and the process of covering nano-silica fillers, the prepared silica gel synthetic leather has strong flexural resistance and abrasion resistance, and through steam treatment, the silica gel synthetic leather is made The main primer layer has good flexibility, environmental protection and no pollution, and has a very wide application prospect.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a preparation method of environment-friendly silica gel synthetic leather. Background technique [0002] The mainstream synthetic leather in the market is a product formed by coating resin slurry such as PU and PVC on the base material. In recent years, silicone synthetic leather has appeared on the market, which is a composite material made of textiles as the base material, impregnated with silicone slurry and coated. Compared with the popular PU synthetic leather on the market, the synthetic leather made of silica gel has excellent characteristics such as environmental protection and non-hydrolysis, but its disadvantages are also obvious, such as poor flex resistance, poor abrasion resistance, and general softness, etc. Therefore, Improving the flexibility, abrasion resistance and softness of silicone synthetic leather is the key technology to expand the application ...
