Abstract

The invention discloses a polylactic acid material for automobile interior trim. The polylactic acid material is prepared from, by weight, 30-35 parts of bamboo fibers, 2-3 parts of antimonous oxide, 5-7 parts of shell powder, 10-12 parts of waterborne polyurethane, 0.2-0.4 part of a silane coupling agent kh570, 1-2 parts of polyethylene wax, 10-13 parts of polyvinyl alcohol, 100-105 parts of polylactic acid, 60-68 parts of dimethylacetamide, 30-35 parts of dimethyl sulfoxide, 9.8-11 parts of hydroxyapatite, 5-6 parts of eggshell powder, 6.3-7 parts of limonene and an appropriate amount of deionized water. The polylactic acid automobile interior trim material prepared by combining the advantages of various materials has the good comprehensive property, is excellent in fireproof property, antistatic property, antibacterial property, weather resistance and the like and has the good prospect by serving as an automobile interior trim material.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polylactic acid material for automotive interior decoration. Background technique [0002] Polylactic acid (PLA) is a polymer obtained by polymerization of lactic acid as the main raw material. Its production process is non-polluting and biodegradable, so it is an ideal green polymer material. In recent years, the application of PLA in the fields of automotive interior, textile, packaging and medicine has been greatly developed. Because of its non-toxic, good biocompatibility, biodegradability and final degradation products are CO2 and H2O, and its performance can be adjusted in a wide range by methods such as copolymerization, blending, molecular modification, and compounding, It has become one of the most valued materials at present. PLA has good strength and rigidity, but poor flexibility, impact performance and heat resistance. If it is used in occasions requir...
