Embodiment Construction

[0013] A car interior material with good recycling performance, made of the following raw materials in parts by weight (kg): bamboo 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, graphene oxide 10, polyethylene glycol 5, polytetrafluoroethylene 5.5, appropriate amount of deionized water;

[0014] The car interior material with good recycling performance 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 temperature until the water evaporates, and finally dry it for later use;

[0016] (2) Soak g...

Abstract

The invention discloses an automotive interior material with high recycling performance. The automotive interior material is prepared from, by weight, 30-35 parts of bamboo fiber, 2-3 parts of antimonous oxide, 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 polyving akohol, 100-105 parts of polylactic acid, 60-68 parts of dimethylacetamide, 30-35 parts of dimethyl sulfoxide, 10-11 parts of oxidized graphene, 5-6 parts of poly-hexanediol, 5.5-6.5 parts of polytetrafluoroethylene and a proper amount of deionized water. The preparing method is simple, the technology is suitable for large-scale production, the recycling performance of the material is high, resource waste is avoided, comprehensive performance is excellent, and the automotive interior material can be in various shapes.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an automobile interior material with good recycling performance. 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 requ...
