Embodiment Construction

[0013] A modified sisal fiber polylactic acid composite environment-friendly automotive interior material, made of the following raw materials in parts by weight (kg): sisal fiber 30, antimony trioxide 2, shell powder 5, water-based polyurethane 10, silane coupling Agent kh5700.2, polyethylene wax 1, polyvinyl alcohol 10, polylactic acid 100, dimethylacetamide 60, dimethyl sulfoxide 30, ceramic microbeads 8, polybenzimidazole 6, wollastonite 7, Appropriate amount of ionized water;

[0014] Described a kind of modified sisal fiber polylactic acid composite environment-friendly automotive interior material is prepared by the following specific steps:

[0015] (1) Dry the bamboo fiber at 105°C for 2 hours and then open it. Add antimony trioxide and shell powder to the water-based polyurethane emulsion (solid content is 20%) and stir evenly, then impregnate the bamboo fiber into the water-based polyurethane In the emulsion, heat to 100°C under 2Pa and keep it at a constant temper...

Abstract

The invention discloses a modified-sisal-fiber-polylactic-acid composite environment-friendly automobile internal decorating material. A sisal fiber is prepared from, by weight, 30-35 parts of sisal fibers, 2-3 parts of antimony trioxide, 5-7 parts of shell powder, 10-12 parts of waterborne polyurethane, 0.2-0.4 part of 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, 8-9 parts of ceramic microbeads, 6-7 parts of polybenzimidazole, 7-8 parts of aedelforsite and a proper amount of deionized water. According to the modified-sisal-fiber-polylactic-acid composite environment-friendly automobile internal decorating material, a preparing method is simple, and the performance of the composite material is greatly improved through the natural sisal fibers; the composite material is natural, degradable, free of environment pollution and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified sisal fiber polylactic acid composite environment-friendly automotive interior material. 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 resistanc...
