Abstract

The invention discloses washing-resistant silicon rubber leather. The washing-resistant silicon rubber leather comprises a cloth base, cloth base combining layer silicon rubber, washing-resistant silicon rubber and washing-resistant bright hand feeling oil. The invention also discloses a coating process of the washing-resistant silicon rubber leather. The process is simple, the production efficiency is high and the production cost is low; no hydrophilic or easy-to-hydrolyze group exists in silicon rubber molecules of the prepared washing-resistant silicon rubber leather, no hydrogen bond or Van der Walls force is generated with a detergent, and an extremely high detergent-resistant property is achieved. The addition type silicon rubber and the base material form stable chemical bond, so even if the washing-resistant silicon rubber leather is cleaned by the detergent under the condition of 90 DEG C, the phenomenon that the adhesion firmness is reduced is avoided. Fluorine-containing silicon rubber with extremely low surface energy and high vinyl silicone oil with high crosslinking density are adopted, and the detergent cannot permeate into the silicon rubber, so that the silicon rubber leather with extremely high washing resistance is obtained.

Description

technical field [0001] The invention relates to the technical field of organosilicon and leather manufacture, in particular to a washing-resistant silicone rubber leather and a coating process of the washing-resistant silicon rubber leather. Background technique [0002] The development history of synthetic leather is not long. The large-scale production of synthetic leather in my country was around the mid-1990s, and PU leather was widely used in the late 1990s. [0003] The application of leather in existing life is very extensive, including clothing, gloves, bags, furniture, shoe uppers and other fields. However, leather is easily hydrolyzed and corroded in a humid environment, and it cannot be cleaned by washing with water. This leads to the problem that PU leather cannot be cleaned quickly and conveniently during use, which brings great benefits to the use of PU synthetic leather. limits.
