Environmental-friendly fire-retardant automotive interior imitation leather material

Abstract

The invention discloses an environmental-friendly fire-retardant automotive interior imitation leather material which is prepared from, by weight, 25-30 parts of wool fiber, 4-5 parts of chitosan, 2-3 parts of titanium dioxide, 0.6-1.0 parts 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 dry linseed oil, 4-5 parts of glycerol, 3-4 parts of glass flake, 5-7 parts of magnesium chloride, and an appropriate amount of deionized water. A method for preparing the automotive interior imitation leather material is simple and controllable. As the automotive interior imitation leather material has good fire-retardant property, hazard of fires to life and property of people is reduced greatly. The automotive interior imitation leather material can be used for producing various automotive interiors and has good application prospect.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant and environmentally friendly automotive imitation leather interior material. Background technique [0002] With the rapid development of the automotive industry, consumers not only value the beauty of the exterior of the car when buying a car, 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 entire vehicle. At present, automotive interior materials include PVC artificial leather and PU artificial leather. The 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 regulation...

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
