Silicone rubber synthesized leather taking foamed silica gel as substrate and manufacture technology thereof

Abstract

The invention discloses silicone rubber synthesized leather taking foamed silica gel as a substrate. The synthesized leather comprises a cloth base, wherein front silicone rubber is coated to the front side of the cloth base, a surface treatment layer is coated to the surface of the front silicone rubber, and foamed silicone rubber is coated to the back of the cloth base; and the front silicone rubber is prepared from the following raw materials in parts by mass: 100 parts of a liquid silicone rubber component A, 100 parts of a liquid silicone rubber component B, 2-5 parts of hydrogen-containing silicon oil, 1-3 parts of a tackifier, 0.5-2 parts of a defoaming agent, 1-3 parts of a silane coupler, 0.1-0.3 part of a platinum catalyst and 10-30 parts of color paste pigment. According to thesilicone rubber synthesized leather, the defect of a traditional PU leather is overcome, the defect that glue is required to adhere sponge is also overcome, the smooth contact like the skin of infantsis brought to users when the silicone rubber synthesized leather is used in a seat of a vehicle, and the comfortable feeling and rebound resilience of traditional adhesive sponge are given to the synthesized leather.

Description

technical field [0001] The invention relates to silicone rubber leather, in particular to a silicone rubber synthetic leather with foamed silica gel as the base and a manufacturing technology for the silicone rubber synthetic leather with the foamed silica gel as the base. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the products used in clothing, food, housing and transportation. Not only in terms of comfort and functionality, but also in terms of environmental protection, higher requirements are put forward for the products used. [0003] When traditional leather is used to make vehicle seats, in order to improve the comfort of use, a layer of sponge is attached to the leather cloth base to increase the elasticity and resilience of the leather. The lamination of the sponge and the cloth base is mainly done by using solvent-based glue. The lamination process will generate a large amount of VO...

AI Technical Summary

Problems solved by technology

This bonding method will not only make the leather not environmentally friendly, but will also pollute the environment, and will also increase the production process and processing costs

At the same time, due to the poor physical properties of the sponge, the use of the sponge will greatly reduce the service life and aesthetics of the vehicle seat
