Problems solved by technology

[0003] However, PVC artificial leather added with polyether-modified siloxane materials still has a certain gap with genuine leather in terms of feel, and cannot meet the increasingly stringent requirements of end customers. The main resin in the coating has poor compatibility, which affects the processing performance. Due to the relatively small molecular weight of such siloxane substances, the binding force with the main main resin is relatively poor, and it is easy to volatilize when heated. Chemical performance also affects

Abstract

The invention provides an animal protein modified water treating agent, comprising 70-100 phr of polycarbonate polyurethane, 10-25 phr of animal protein powder, 3-5 phr of long-chain aliphatic alkyl sodium sulfate, 0.2-0.3 phr of a photostabilizer, 3-6 phr of a crosslinker, and 100 phr of deionized water. The water treating agent optimized with animal proteins forms a uniform coating layer on thesurface of PVC (polyvinyl chloride); therefore, PVC artificial leather has the advanced touch, as smooth as skin, and fogging performance of the PVC artificial leather is improved.

Description

technical field [0001] The invention relates to an animal protein modified water treatment agent, its preparation method and its application. Background technique [0002] PVC artificial leather is a covering material widely used in automotive interiors. Due to its stable structure and relatively cheap and easy availability, it is more and more widely used in car seats, headrests, door panels, central control armrests and dashboards. In recent years, more and more automobile manufacturers and end consumers are pursuing the comfort of automobile interiors. Among them, PVC artificial leather materials with a high-grade feel similar to genuine leather have attracted more and more attention from customers and end consumers. The traditional method is to The PVC artificial leather surface treatment agent introduces polyether-modified siloxane substances to improve the feel of PVC artificial leather. [0003] However, PVC artificial leather added with polyether-modified siloxane m...
