Description
Technical field
The present invention relates to automotive interior material technical field, particularly relate to a kind of environment-friendly type automobile inner decoration matrix material and preparation method thereof.
Background technology
The inside gadget of car generally refers to component and the material such as dividing plate, door panel, panel assembly, handrail, carpet of car.For other parts on car, they do not have anything to affect on the operating performance of vehicle, but its appearance is covered all at one glance, and represent the image of whole car, which is better and which is worse, decide reputation and the class of car, decide the purpose that people select car.In addition, for car, although the inside gadget spare and accessory parts that to be some complementary, they will bear vibration damping, heat insulation, the function such as sound-absorbing and screening sound, play very important effect to the comfortableness of car.Automobile industry while flourish, also brings environmental pollution and the serious greatly negative impact of energy shortage two all over the world.According to investigations, nearly 35% used as the fuel of automobile in oil consumption product, along with consuming excessively of petroleum resources, automobile industry must be adjusted accordingly, and lightweight and energy-conserving and environment-protective become the theme of international automobile industrial research.Biodegradable high-molecular and goods thereof are focuses of various countries scientist research in the last few years, exploitation, production, developed country not only government's substantial contribution drops into, and also drops into a large amount of people's material resourcess to major company, scientific research institution and university research department and researches and develops.Because poly(lactic acid) has excellent biological degradability and biocompatibility, be finally decomposed into carbonic acid gas and water in the environment, environment is not polluted, therefore one of study hotspot becoming degradable material.Polylactic resin derives from the biological raw material of non-petroleum base, there is again good over-all properties, receive attention and the favor of automobile industry, the Japanese firms such as Toyota, Mitsubishi, Mazda have taken the lead in applying poly(lactic acid) interior products on its brand automobile, domestic if Chery Automobiles is also at the automobile-used poly-lactic acid products of exploitation.But due to crystallization of polylactic acid resin speed very slow, moulded products shrinking percentage is large, and matter own is crisp, and processing heat stability is poor, and the shortcoming such as goods poor durability, limits its application as engineering plastics.Therefore, in the urgent need to carrying out activeness and quietness, the multiple elements design study on the modification such as heat-resisting to green plastic polylactic resin.Add automobile fire phenomenon frequently to occur, private car fire is in rising trend, the reason of automobile fire is because automobile self-technique level is uneven on the one hand, on the other hand automobile self uses in structured material that some is inflammable material, comprises automotive trim macromolecular material polypropylene, polycarbonate and degradation material poly(lactic acid) etc.Therefore, the flame retardant resistance of poly-lactic acid material is also needed to carry out modification.Simultaneously because car noise brings very large impact to occupant in the process of moving, be directly connected to the health of occupant.So car noise just becomes the major criterion weighing automobile its own mechanical performance and comfort property quality.So, be badly in need of a kind of automotive interior material having the functions such as environmental protection, fire-retardant, sound-absorbing concurrently of invention.
