Thick automobile inner chamber leather with pressure resistance and friction-resistant color fastness

Abstract

The invention discloses thick automobile inner chamber leather with pressure resistance and friction-resistant color fastness. The thick automobile inner chamber comprises a base cloth layer and a surface layer coating one surface of the base cloth layer, wherein the surface layer is a four-layer structure and comprises a water-base PU bottom layer, a water-base PU foamed layer, a water-base PU reinforcing layer and a water-base PU surface layer which are sequentially connected. According to the thick automobile inner chamber leather, the base cloth layer has the effects of resisting bacteria and ultraviolet light and retarding combustion; the surface layer is a four-layer structure and has strong leather sensation, and the four layers are made of a water-base polyurethane emulsion, so that the environmental protection property is good, the strength is high, and the water repellency and the gas permeability are strong; the PU foamed layer is of a hollow formed structure and is light, so that the automobile inner chamber leather is endowed with relatively rebound resilience and compression strength; nano-TiO2 powder, nano-ZnO powder and polyol fatty acid ester are further added into the water-base PU surface layer, so that the automobile inner chamber leather has relatively strong light aging resistance and static electricity resistance; by utilizing a Dow Corning DC-57 organosilicon polyether copolymer, the automobile inner chamber leather is smooth and wearable and has strong friction-resistant color fastness.

Description

【Technical field】 [0001] The invention relates to the technical field of synthetic leather, in particular to a thick automobile interior leather with color fastness to pressure and rubbing. 【Background technique】 [0002] Due to population growth, environmental protection and increasing social demands, genuine leather has been unable to meet the needs of people's daily life. The environmental pollution and natural resource shortage caused by the processing of genuine leather has prompted the development of synthetic leather. As a substitute for natural leather, artificial leather can not only overcome the disadvantages of low leather utilization, poor wear resistance, low tear strength, uneven texture, and difficulty in cutting, but also solve the problem of the increasing shortage of leather resources and its environmental impact during processing. The problem of causing great pollution [0003] Artificial leather is widely used in the field of automotive interiors because...
