Description

A kind of low gloss for thin-walled automobile door plate, inexpensive PP composite material and Its preparation method
Technical field
The present invention relates to a kind of for the low gloss of thin-walled automobile door plate, inexpensive PP composite material and its preparation side Method, belongs to polymer modification and manufacture field.
Background technology
With the rapid development of economy, China's automobile volume of production and marketing continues to hold a post or title the whole world first, annual production in 2016 for continuous 8 years Pin surpasses 28,000,000, increases by 14.5% and 13.7% on a year-on-year basis.It is acceleration consumption and the ring of the energy under so high speedup The lasting exacerbation of border load.Under the overall situation of currently internationalization energy-conserving and environment-protective, the lightweight of automobile has become world car The trend of development.Root is it was found that vehicle complete vehicle weight reduction 10%, fuel efficiency can improve 6%~8%, i.e. vehicle weight and drop Low by 1%, oil consumption can reduce about 0.7%.Light-weighted meaning is not only energy-saving and emission-reduction, and is the key of auto industry Technology, can improve ability to develop independently, the product competitiveness of enterprise.
Car thin-wall is to realize light-weighted main path, and polypropylene material is due to light weight, inexpensive and excellent comprehensive Performance is closed, is widely used in automobile industry, automobile interior exterior decorations are applied especially to, such as：Thin-walled door-plate, thin-wall bumper etc..Should Polypropylene material for car thin-wall needs to meet high flowing, high-modulus and high tenacity simultaneously, and general thin-walled property gathers Propylene material is high due to mobility, and the low product glossiness for causing shaping of molecular weight is high, comfortableness and peace that influence automobile is used Quan Xing；And can cause being significantly increased for material cost, it is necessary to reach high tenacity on the premise of high-modulus is met.
The content of the invention
In order to solve the deficiency of existing thin-walled property polypropylene material high glaze and high cost, it is an object of the invention to provide one Plant the low gloss for being used for thin-walled automobile door plate, inexpensive PP composite material and preparation method thereof, the PP composite material The gloss of material can be substantially reduced on the premise of high flowing, high-modulus and high tenacity is met, at the same reduce material into This, significantly improves product competitiveness, and can be widely applied in other automobile interior exteriors decorations product.
The present invention is achieved through the following technical solutions：
A kind of low gloss for thin-walled automobile door plate, inexpensive PP composite material, according to following percentage by weight The raw material of meter is formulated：
The polypropylene is at least one of HOPP and block copolymerization polypropylene.
The HOPP is under the conditions of 230 DEG C of * 2.16kg, and melt flow rate (MFR) is 20~100g/10min, and it is tied Brilliant degree is more than 75%, isotacticity more than 98%.
The block copolymerization polypropylene is under the conditions of 230 DEG C of * 2.16kg, and melt flow rate (MFR) is 30~100g/10min, Izod notched impact strength is 4~10kJ/m2。
The HDPE resin A is under the conditions of 190 DEG C of * 2.16kg, and melt flow rate (MFR) is 0.1~1g/10min, is divided equally again Son amount more than 110,000, polydispersity coefficient 9.0~9.5.
The toughener is ethylene-octene copolymer, polyethylene, hydrogenated styrene-butadiene-styrene block copolymers With mixture more than one or both of ethylene propylene diene rubber.
The filler is mixture more than one or both of talcum powder, calcium carbonate, whisker and glass.
Described auxiliary agent is antioxidant, weather resisting agent and processing aid.
Described antioxidant is one or both of antioxidant 1010, irgasfos 168 and anti-oxidant DLTP, described weather-proof Agent is hindered amine as light stabilizer LA-402AF or UV-3808PP5, and the processing aid is zinc stearate or erucic acid.
This low gloss, the method for inexpensive PP composite material for thin-walled automobile door plate is prepared, its step is：
(1) 50~75% polypropylene, 5~12% HDPE resin A, 0~15% toughener and 0~3% are helped Agent is put into high mixer high speed and mixes 3~5min, and rotating speed is more than 400r/min；
(2) mixture obtained by (1) is added to extruding pelletization in double screw extruder by main feeding, filler is fed by side Mode is added to melting extrusion in extruder and granulated；Wherein, the speed-frequency of double screw extruder is 30~50Hz, the area of temperature one For 160 DEG C, remaining temperature is 180 DEG C~230 DEG C, and vacuum is more than -0.06MPa.
Compared with existing thin-walled property door-plate polypropylene material, it is an advantage of the invention that：
1. the HDPE resin A of addition in the range of the specific coefficient of dispersion, is easily led due to higher molecular weight Cause material crystalline degree of perfection different, make surface diverse location angle of reflection different, diffusing reflection is formed, so as to reduce lustrous surface Degree, and the thin-walled door-plate of low gloss can not only improve the security of automobile, can more lift the comfortableness driven；
2. the HDPE resin A of addition produces cooperative effect with toughener, on the premise of identical toughness, toughness reinforcing can be reduced The addition of agent, not only can further improve the rigidity of material, lift material combination property, and can reduce material into This, so as to provide more preferable product competitiveness.
Embodiment
With reference to specific embodiment, the present invention is described further：
By weight percentage by 50~75% polypropylene, 5~12% HDPE resin A, 0~15% toughener and 0 ~3% auxiliary agent is put into high mixer high speed and mixes 3~5min, and rotating speed is more than 400r/min.The mixture mixed is led to Cross main feeding and be added to extruding pelletization in double screw extruder, filler is added to melting extrusion in extruder by side hello mode and made Grain；Wherein, the speed-frequency of double screw extruder is 30~50Hz, and the area of temperature one is 160 DEG C, and remaining temperature is 180 DEG C~230 DEG C, vacuum is more than -0.06MPa.
