Description
Technical field
The present invention relates to automotive field, be a kind of low smell high-performance polypropylene compound material and preparation method thereof, belong to automobile polypropylene composite material technical field.
Background technology
Along with the raising of people's quality of life, people are no longer that the vehicles are so simple to the requirement of automobile, and focus also expands to upholstery, the spacious degree of interior space, the comfort level taken from vehicle operation performance, and even Air quality.Especially, after a little human consumer occurs the untoward reactions such as dizziness, vomiting after driving new car, in-car air quality also becomes the emphasis of concern in recent years.
Research shows that in car, the source of smell is many-sided, but main relevant with the use material of upholstery and component etc., this be due to these materials in use, meeting in various degree discharges certain irritating smell.In order to limit the smell of vehicle material, the depots such as masses, Ford have also put into effect odor standards in succession.Modified polypropylene composite material has widespread use in the component such as exterior trim, air-conditioning, air filter in automobile.But the appearance of Ge great main engine plants new standard makes conventional polypropylene matrix material be difficult to meet automobile factory's requirement, develop low odor polypropylene composite material for this reason and seemed particularly important.
The source of polypropylene composite material smell forms primarily of following components.One, polypropylene bulk material smell is higher, and this is the introducing due to the factor such as catalyzer in the course of the polymerization process; Two, polypropylene thermal stability is not good, occurs decomposing producing volatile small molecules in modifying process; The introducing of the auxiliary agent three, added in modifying process and filler etc.
At present in order to prepare low odor polypropylene composite material, prior art mainly divides following three kinds: one to be adsorptive type, add the sorbing materials such as vegetable fibre, hydrophobic molecule sieve, porous silica, porous alumina, activated carbon (CN 103589072 A) in the composite to reduce micromolecular distributing, and the use of gac makes material color can only be confined to black; Two is chemical reaction type, add the materials such as reactive Viscotrol C (CN 1043111999A) in the composite and volatile small molecules carries out transesterification reaction, or sequestrant makes volatile small molecules become large thus makes it fixing in the material to reduce its volatilization possibility, but there will be fuel-displaced phenomenon along with the increase product surface of time; Three be in process with process aftertreatment type, United States Patent (USP) (USP 5109056) adopts high temperature to extrude, and vacuumize in extrusion, finally baking is for a long time carried out to remove smell to product, but baking will certainly cause material ageing-resistant performance to reduce for a long time.
Summary of the invention
The invention provides a kind of low smell high-performance polypropylene compound material and preparation method thereof, oder levels is low, and mechanical property obtains more improvement.
In order to realize above object, the solution of the present invention adds a kind of odor suppressing agents in the basic components of polypropylene composite material, while this odor suppressing agents can effectively reduce polypropylene composite material smell, or increases the mechanical property of polypropylene composite material.Its feature is, the odor suppressing agents added can be made up of atlapulgite separately, also can be combined by sorbing materials such as atlapulgite and molecular sieve, diatomite, zeolite, gacs.The use of this odor suppressing agents effectively can reduce the release of volatile material in polypropylene composite material, thus reaches the object reducing smell.In addition, due to the nanometer laminated structure that atlapulgite is natural, after polypropylene is peeled off its effective intercalation, mean in matrix material and contain polypropylene/atlapulgite nano composite material, for this reason polypropylene composite material mechanical property thus had better raising.
The present invention is realized by following technical scheme:
A kind of low smell high-performance polypropylene compound material, is mixed by the raw material of following massfraction:
Described polypropylene is have one in the low smell high-crystallinity polypropylene of different mobility and block copolymerization polypropylene or both mixtures.
Described filler is one or more the mixture in talcum powder, calcium carbonate, mica powder, and its packing material size is at 600 ~ 6000 orders.
Described odor suppressing agents is by atlapulgite, or the mixture that atlapulgite mixes with sorbing material forms, and described sorbing material is molecular sieve, diatomite, zeolite, gac.
Described toughner is copolymer p OE or the high density polyethylene of ethene and octene.
Described heat-resistant agent be selected from phenolic antioxidant, phosphite ester kind antioxidant, metal passivator 1010,3114, DSTDP, 168, photostabilizer V680,944, one or more in UV light absorber 3853,770 are composite.
Described lubricant is stearate, and described stearate is Zinic stearas, calcium stearate; Ethylene bis stearamide, polyethylene wax, at least one in grafting ethylene bis stearamide.
Present invention also offers the preparation method of this low smell high-performance polypropylene compound material, is realized by following step:
(1) polypropylene 50 ~ 80%, filler 10 ~ 45%, odor suppressing agents 2 ~ 6%, toughner 0 ~ 10%, heat-resistant agent 0.1 ~ 2% and lubricant 0.1 ~ 2% is taken by joining massfraction;
(2) in high mixer, successively add polypropylene, white oil, toughner, heat-resistant agent, lubricant and odor suppressing agents, stir and add filler after 1 ~ 2 minute, total mixing time was at 4 ~ 10 minutes;
(3) above-mentioned material is extruded in the parallel double-screw machine of high vacuum or two vacuum, cross water and granulation; Extrusion temperature is between 200 ~ 230 DEG C, and the residence time was at 1 ~ 2 minute;
