Problems solved by technology

The disadvantage is that the wear resistance, smoothness and anti-dust absorption of the surface material are not described, and the practicability is not good
[0012] CN201342821Y, CN1021174262A and CN202247476U etc. have invented the use of release film, embossing treatment and additional decorative adhesive layer to give silicone leather surface lines and patterns, but they have not stated that additional layers have effects on wear resistance, smoothness and anti-adsorption dust. any improvement
[0013] To sum up, the previous work started from different application directions and proposed some solutions to the problems of silicone leather in terms of slippery feeling, dust absorption resistance, adhesive strength, wear resistance and scratch resistance, etc. Clearly and completely propose a technical solution that can comprehensively solve the problems of high surface friction, easy to absorb dust, poor bond strength, poor wear resistance and poor scratch resistance in silicone synthetic leather composite materials

Abstract

The invention discloses organosilicon synthetic leather adopting a three-layer structure and a preparation method thereof. The organosilicon synthetic leather is bonded by a base material, bottom layer glue and surface layer glue in sequence. According to the organosilicon synthetic leather adopting the three-layer structure, through the reasonable design of the chemical composition of the bottom layer glue and the surface layer glue, the bottom layer glue provides a firm interlamination bonding function for the two connecting surfaces under the combined action of various chemical reactions, and is endowed with the characteristics of softness and smoothness of the organosilicon synthetic leather, the surface layer glue is endowed with the characteristics of being dry, comfortable and wearable of the organosilicon synthetic leather, so that the organosilicon synthetic leather has the characteristics that dust adsorption is reduced, and the wear resistance, the scrape resistance and the scratch resistance are improved.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather. More specifically, the invention relates to a three-layer organosilicon synthetic leather with soft, smooth, dry and wear-resistant properties and a preparation method thereof. Background technique [0002] Silicone synthetic leather is a composite material composed of textile (or synthetic leather) base material, primer glue, surface glue and surface coating layer bonded in sequence. [0003] Compared with the very popular and best-selling polyurethane synthetic leather in the market, silicone synthetic leather has not achieved substantial promotion. The fundamental reason is the excellent cost performance of polyurethane synthetic leather. However, polyurethane synthetic leather always has defects in toxicity, environmental protection, weather resistance and water resistance, while silicone materials have environmental protection, weather resistance and hydrophobic properties, so sili...
