Attractive recyclable automobile interior material

Abstract

The invention discloses an attractive recyclable automobile interior material. The attractive recyclable automobile interior material is prepared from, by weight, 25-30 parts of wool fiber, 4-5 parts of chitosan, 2-3 parts of titanium dioxide, 0.6-1 part of polyethylene glycol, 100-110 parts of waterborne polyurethane, 0.2-0.4 part of didodecyldimethylammonium bromide, 5-6 parts of clay, 6-7 parts of polyvinylidene fluoride, 4-5 parts of resin gelatin powder, 4-5 parts of bone meal, 5-6 parts of scaly aluminum sheets and a proper amount of deionized water. The material recycling efficiency is high, the appearance is attractive and elegant, and the automobile interior material is excellent in performance and long in service life and has the good application prospect.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an aesthetically pleasing and recyclable automotive interior material. Background technique [0002] With the rapid development of the automobile industry, consumers not only pay attention to the beauty of the exterior shape of the car when buying a car, but more and more consumers have put forward higher requirements for the beauty, functionality and low emission of automotive interior materials. Automotive interior materials have become an important factor affecting the quality and grade of the vehicle. At present, the automotive interior materials include PVC artificial leather, PU artificial leather and so on. Materials used for automotive interiors should have good performance indicators, such as light resistance, low temperature resistance, flexibility, good flame retardancy, and low fogging. At the same time, they must meet the requirements of laws and regulatio...

Problems solved by technology

However, there are more or less problems in the commonly used automotive interior materials, which cannot meet the requirements of mass consumers for interior materials. With the slogan of energy saving, emission reduction and environmental protection, it is necessary to develop new environmentally friendly recyclable materials. automotive interior materials

[0003] Polyurethane materials have been applied to many fields because of their unique structure and excellent performance, and have always been a research hotspot. Water-based polyurethane materials have broad application prospects because of their low cost, no pollution, and good flexibility. Polyurethane processing The synthetic leather and artificial leather produced have good advantages, such as high strength, good wear resistance, good flex resistance, low temperature resistance, oil resistance, and good chemical resistance, but the disadvantage is the water resistance and heat resistance of water-based polyurethane. Low moisture permeability and poor moisture permeability will seriously affect the service life of the material and the comfort of the human body, and reduce the performance of the car. The present invention focuses on the improvement of this aspect in order to meet people's requirements for automotive interior materials
