Description
Technical field
The present invention relates to a kind of automotive trim matrix material, particularly modified polypropylene material and preparation method thereof for a kind of roof of the vehicle.
Background technology
Automobile has become one of main traffic instrument in modern society; it is major power consumer; it is generally acknowledged trolley part loss of weight 1%; fuel-economizing also nearly 1%; thereby the weight that reduces automotive part is to energy-conservation all significant with environment protection; wherein most important method is to mould Dai Gang, makes isotatic polypropylene (PP) material be widely used in collision bumper, door-plate, instrument desk, column guard board etc.Good Heat-resistance, the counter-bending fatigability of isotatic polypropylene (PP) are good, price is low, of many uses; But PP impelling strength is low and creep resistance is poor, molding shrinkage is large, dimensional stability is bad; So isotatic polypropylene raw material can not directly be used at automotive field, must mostly add mineral filler or toughner to adjust the molding shrinkage of material through modification, obtain dimensional stabilizing, the product requirements such as good toughness.But so can cause the density of formed material to rise, be unfavorable for the lightweight of Integral automobile.
Summary of the invention
The object of this invention is to provide modified polypropylene material and preparation method thereof for a kind of roof of the vehicle.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
A roof of the vehicle modified polypropylene material, is made by the raw material of following weight part: isotatic polypropylene 80-85, stearic acid 3-4, captax 1-2, dibasic lead phosphite 1-2, ABS resin 30-34, PP resin 9-13, kaolin powder 23-28, aluminium hydroxide 12-15, Microcrystalline Wax 4-6, barium sulfate 10-15, zinc oxide 3-5, n-BMA 4-5, auxiliary agent 6-9;
Described auxiliary agent is made by the raw material of following weight part: described auxiliary agent is made by the raw material of following weight part: clay 10-12, lapis amiridis 3-4, anti-aging agent ODA 1-2, titanate coupling agent TMC-TTS 3-4, primary ammonium phosphate 1-2, magnetite 3-4, Zinc Stearate 2-3, triethyl citrate 35-40, Tenox PG 3-4, nano titanium oxide 0.2-0.3, nano diatomite powder 1-2, coix seed oil 2-3, vanadium diboride 1-2, l-Epicatechol 2-3; Preparation method sends into clay, magnetite in calcining furnace and calcine 2-3 hour at 720-740 ℃, then, takes out, and sends in the hydrochloric acid soln of 10-15% and soaks 2-3 hour, filters, and obtains filter residue, with clear water, cleans, and dries, grinds to form 400-600 order powder; Gained powder mixes with other remaining component, is heated to 60-70 ℃, and stirring reaction 40-50 minute is cooling, grinds to form slurry, obtains.
Roof of the vehicle modified polypropylene material of the present invention, by following concrete steps, made: isotatic polypropylene is heated to molten state, adds stearic acid, captax, dibasic lead phosphite, barium sulfate, zinc oxide 3-5, n-BMA, kaolin powder to stir and mediate 15-25 minute; Add again auxiliary agent and all the other remaining components, be heated to 180-190 ℃, stir 8-10 minute, send into and on twin screw extruder, melt extrude granulation, cooling and get final product.
Excellent effect of the present invention is: the present invention has high rigidity, height is heat-resisting and cost is low advantage, and scratch-resistant is good, cost is low and excellent combination property, and preparation is simple, and this material can be applicable to make roof of the vehicle and inside gadget.
