Abstract

The invention relates to a fully degradable automobile internal and external decoration material and a preparation method and an application thereof. The preparation method of the automobile internal and external decoration material includes that a natural fiber with a water content of below 0.2% is processed by a silane coupling agent, the processed natural fiber and a polylactic acid fiber which has a density of 1.22g per cubic centimeter are respectively drawn and continuously fed into a mixed slurry to be subjected to an immersion treatment for 60 to 180 seconds, the natural fiber and the polylactic acid fiber which are subjected to the immersion treatment are dried until the water content is below 0.2%, then the natural fiber and the polylactic acid fiber are guided into a double-screw extruder, and the natural fiber and the polylactic acid fiber are extruded together through the double-screw extruder to obtain the automobile internal and external decoration material. The natural fiber and polylactic acid are used as raw materials for the automobile internal and external decoration material, and raw material source is environment-friendly, renewable and fully degradable.

Description

technical field [0001] The invention relates to an automobile interior and exterior decoration material and its preparation method and application, in particular to an automobile interior and exterior decoration material whose raw material source is green, renewable and completely degradable, and its preparation method and application. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, the fiber materials used in automobile interior decoration will develop from economical and practical to functional, fashionable, lightweight and green. The chemical fibers commonly used in automobile decoration materials are as follows. 1. Functional fibers Automotive decorative textiles have high requirements for new functional fiber raw materials, and their processing and finishing processes are also very complicated. In addition to meeting the general requirements of textiles, these textiles also have special requ...
