Heat-resistance polypropylene material and preparation method thereof for a kind of automotive upholstery
Technical field
The present invention relates to a kind of automotive trim matrix material, particularly heat-resistance polypropylene material and preparation method thereof for a kind of automotive upholstery.
Background technology
Isotatic polypropylene is a kind of thermoplastic resin that can be made by propylene polymerization, it not only has the advantages such as good processability, high, the resistance to gasoline of toughness and chemical proofing are good, and light weight, inexpensive, thereby it is widely used, as can be used for, produce the goods such as inner and outer decorative parts of automobile and household electrical appliance component.But pure isotatic polypropylene is comparatively not enough at aspects such as thermotolerance and rigidity, cannot meet better the requirement of goods.
Summary of the invention
The object of this invention is to provide heat-resistance polypropylene material and preparation method thereof for a kind of automotive upholstery.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
An automotive upholstery heat-resistance polypropylene material, is made by the raw material of following weight part: isotatic polypropylene 80-90, polynite 14-18, polystyrene 30-34, PP resin 9-13, captax 1-2, silane resin acceptor kh-550 2-3, Tai-Ace S 150 23-25, Vanay 8-10, Sodium hexametaphosphate 99 3-4, the cruel triamine 1-2 of hempa, antioxidant NBC 1-2, hard kaoline 12-15, 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.
Automotive upholstery of the present invention heat-resistance polypropylene material, by following concrete steps, made: isotatic polypropylene is heated to molten state, adds Tai-Ace S 150, Vanay, Sodium hexametaphosphate 99, the cruel triamine of hempa, antioxidant NBC, hard kaoline to stir and mediate 20-25 minute; Add again auxiliary agent and all the other remaining components, be heated to 200-220 ℃, stir 7-10 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 adds auxiliary agent, can strengthen the thermotolerance of isotatic polypropylene, and density is low, and light weight is wear-resisting, is conducive to application, processes smooth and easyly, and production efficiency is high, the low and excellent combination property of cost.
Embodiment
Below by specific examples, the present invention is described in detail.
An automotive upholstery heat-resistance polypropylene material, by following weight part (kilogram) raw material make: isotatic polypropylene 80, polynite 14, polystyrene 30, PP resin 9, captax 1, silane resin acceptor kh-550 2, Tai-Ace S 150 23, Vanay 8, Sodium hexametaphosphate 99 3, the cruel triamine 1 of hempa, antioxidant NBC 1, hard kaoline 12, auxiliary agent 6;
Described auxiliary agent by following weight part (kilogram) raw material make: clay 10, lapis amiridis 3, anti-aging agent ODA 1, titanate coupling agent TMC-TTS 3, primary ammonium phosphate 1, magnetite 4, Zinc Stearate 2, triethyl citrate 35, Tenox PG 3, nano titanium oxide 0.2, nano diatomite powder 1, coix seed oil 3, vanadium diboride 1, l-Epicatechol 2; 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.
Automotive upholstery of the present invention heat-resistance polypropylene material, by following concrete steps, made: isotatic polypropylene is heated to molten state, adds Tai-Ace S 150, Vanay, Sodium hexametaphosphate 99, the cruel triamine of hempa, antioxidant NBC, hard kaoline to stir and mediate 20-25 minute; Add again auxiliary agent and all the other remaining components, be heated to 200-220 ℃, stir 7-10 minute, send into and on twin screw extruder, melt extrude granulation, cooling and get final product.
Products obtained therefrom is tested through iso standard, and melting that test obtains refers to be that 18g/10min, tensile strength are that 26.5Mpa, flexural strength are that 37.2Mpa, modulus in flexure are 1850Mpa.
