AI Technical Summary

Technical Problem

Existing silicone leather manufacturing processes suffer from problems such as lengthy production processes, large equipment investments, poor interfacial bonding, limited surface decoration, and difficulty in achieving both tactile feel and mechanical properties.

Method used

A direct coating process using modified hydrogen-containing silicone oil and fiber cloth substrate is adopted. Modified hydrogen-containing silicone oils A and B form a strong interfacial bond with the fiber cloth substrate, modified silica is used to enhance mechanical properties, and covalent bonds are formed through a gradient vulcanization process, simplifying the production process.

Benefits of technology

It achieves strong interface bonding, good mechanical properties and soft feel, simplifies the production process, reduces material costs and production efficiency, improves production efficiency, and enhances the product's excellent and durable adhesion, which is significantly better than the technical effect of the comparative example, indicating that the product has excellent and durable adhesion; the wear reduction enhances the UV aging resistance performance.

Abstract

The invention discloses a coating material for an organic silicon and fiber cloth compound and a forming process. The coating material comprises a bottom layer and a thin layer, the bottom layer contains modified hydrogen-containing silicone oil A (containing polyether and quaternary ammonium salt), and the thin layer contains modified hydrogen-containing silicone oil B (containing epoxy group) and modified white carbon black. Through gradient vulcanization of the semi-cured bottom layer and the completely-cured thin layer, release paper is not needed, the production process is simplified, the cost is low, and the environmental protection property is good. The coating material is good in weather resistance, soft in hand feeling and clear in surface pattern, and the problems that existing silica gel leather is poor in interface bonding force, insufficient in wear resistance, difficult to consider both hand feeling and mechanical property and limited in decoration are solved.
