Description
Technical field
The present invention relates to automotive interior material technical field, particularly relate to composite polylactic acid material for car interior trim parts of a kind of Silver Nitrate silicon-dioxide synergy modification 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.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides composite polylactic acid material for car interior trim parts of a kind of Silver Nitrate silicon-dioxide synergy modification and preparation method thereof.
The present invention is achieved by the following technical solutions:
A composite polylactic acid material for car interior trim parts for Silver Nitrate silicon-dioxide synergy modification, is made up of the raw material of following weight part: poly(lactic acid) 100-103, nanmeter antimong trioxide 3.5-4, TDE 10-11, SEBS25-27, bastose 60-62, porous silica 7-8, graphene oxide 5-6, dehydrated alcohol is appropriate, aminopropyltriethoxywerene werene 1-1.2, Silver Nitrate 2-3, gelatin 5-6, water are appropriate.
The composite polylactic acid material for car interior trim parts of described a kind of Silver Nitrate silicon-dioxide synergy modification, be made up of following concrete steps:
(1) by stand-by for poly(lactic acid) 80 DEG C of dryings 10 hours in vacuum drying oven, nanmeter antimong trioxide, TDE respectively in baking oven at 60 DEG C dry 5 hours and 8 hours stand-by; Dried material is put into homogenizer, after stirring 10 minutes with the speed of 1000 revs/min, add SEBS, mixture is sent into the temperature at 175 DEG C in twin screw extruder by continuation stirring after 10 minutes, screw speed is extruding pelletization under the processing condition of 150 revs/min, obtains polydactyl acid master batch;
(2) will polydactyl acid master batch send in extruder type spinning machine carry out blended melting and extruding spinning (controlling Screw Extrusion speed is 250 revs/min, spray silk melt temperature controls at 200 DEG C), then the protofilament of ejection is cooled through water-bath, control bath temperature at 20 DEG C, by the warm air drying of fiber with 120-130 DEG C after water-bath cooling, obtain modified polylactic acid fiber; Bastose is carried out shredding process, and the bastose after process and modified polylactic acid fiber carry out blending drafting, obtain blend fiber bar;
(3) aminopropyltriethoxywerene werene is dissolved in the dehydrated alcohol of 20 times amount, then porous silica is added, baking oven is put into after stirring, with the temperature 24 hours of 40 DEG C, after taking-up, modified porous silica is cleaned with water, again modified porous silica is put into the Silver Nitrate being dissolved in 30 times amount dehydrated alcohols, continue to put into baking oven, with the temperature 24 hours of 40 DEG C, put into baking oven with after water cleaning after taking-up, dry with the temperature of 60 DEG C, obtain the silicon-dioxide of load silver ion; The water of 30 times amount will be added in gelatin, be heated to fully swelling, then add silicon-dioxide and all the other remaining components of above-mentioned obtained load silver ion, fully stir 30 minutes with the speed of 500 revs/min, obtain dipping sizing agent;
(4) the blend fiber bar that step (2) obtains is put into dipping sizing agent process to take out after 30 minutes, put into air dry oven, be dried to water content with the temperature of 90 DEG C and be less than 0.2%, then the blend fiber bar of drying is imported twin screw extruder, controlling extrusion temperature is 170 DEG C, and namely extruding pelletization obtains material of the present invention.
Advantage of the present invention is: first the present invention adds nanmeter antimong trioxide, in the polymeric material scattered, can form shell at burning surface, plays heat insulation and intercepts the effect that inflammable gas moves to burning surface; The interpolation of collaborative TDE, react with nanmeter antimong trioxide the antimony tribro-generated, slow down further or stop combustion reactions, play good flame retardant effect, improve the shock strength of polymkeric substance, elongation at break, flow rate, there is good molding processibility.Simultaneously using the toughner of SEBS as poly(lactic acid), there is good toughening effect, simultaneously the shock strength of the great improving product of energy.
