Description
Technical field
The present invention relates to a kind of glass fiber reinforced polypropylene composite material, and in particular to one kind is ultralow to distribute fiberglass reinforced poly- third
Alkene composite and preparation method thereof.
Background technology
With the fast development of auto industry, the time that people stop in the car is more and more long, and in-car air quality will
The health of people is affected to a greater extent.Domestic first national standard for in-car air quality《Air in passenger car
Quality evaluation guide》The formal implementation of GB/T 27630, how this will also improve in-car air quality and push research heat to again
Point.Research finds, in-car air pollution degree sometimes over car outside 10 times.Contaminated air is main next in automobile bodies
Source is the VOC emission of interior material, free formaldehyde, alkane that the textile for being used, leather product or plastic products etc. are evaporated
Various volatile organic compounds such as hydrocarbon, benzene,toluene,xylene and aldehydes.These volatile organic compounds can cause respiratory tract and nerveous system
The disease of the aspects such as system, drastically influence the healthy of people.
Due to its density, gently, rigidly the characteristic such as good obtains more and more should fiber glass reinforced polypropylene material on automobile
With.Fiber glass reinforced polypropylene material generally needs to add compatilizer to improve the interface compatibility of glass and resin, compatilizer by
In there is peroxide to remain, glass fiber reinforced materials easily bring smell and VOC problems, therefore, low smell, low VOC fiberglass reinforceds
Polypropylene turns into a study hotspot always.
The A of Chinese patent CN 103342859 disclose a kind of low smell, low VOC glass fiber reinforced polypropylene composite materials and
Its preparation method, the material includes each component of following weight percent content：Polypropylene 53~83%, glass 10~
40%, compatilizer 2~5%, eliminating smell agent 1~2%, auxiliary agent 0.1~0.3%；The invention further relates to the preparation method of previous materials,
Comprise the following steps：Weight percent weighs each component, is put into high-speed mixer and mixing, discharging, then uses double screw extruder
Extruding pelletization.The eliminating smell agent used in the patent of invention is the compound of nano zine oxide and nano titanium oxide, both things
Matter is two kinds of conventional Chinese whites, plays a part of to colour and lifted whiteness, which has limited true qualities material and coloured material
Use.
China Patent Publication No. CN102030945A discloses a kind of low smell glass fiber reinforced polypropylene composite material
And preparation method thereof, the material includes each component of following weight percent content：Polypropylene 32-91%, glass 5.0~
50%th, compatilizer 2~8%, odor suppressing agents (compound system of zinc ricinate, metal oxide and clay pit object) 1~
6%th, other auxiliary agents 1~4%；During preparation, weight percent weighs each component, by other components and smell in addition to glass
Inhibitor is premixed, and is placed in twin-screw extrusion owner's spout, adds glass, blending, 220~240 DEG C of extruding pelletizations.The invention is special
Material smell is reduced in profit and uses odor suppressing agents, played and prevent material from distributing, but it is absorption that this method plays
Effect, still in material internal, material can be slowly discharged during use afterwards, it is impossible to from root for smell and small molecule material
Smell and VOC are solved the problems, such as in sheet.
The content of the invention
It is an object of the invention to the defect for overcoming above-mentioned prior art to exist, there is provided a kind of ultralow fiberglass reinforced that distributes gathers
Acrylic composite and preparation method thereof.It is of the invention it is ultralow distribute that fiber glass reinforced polypropylene material uses help that to wave agent be one kind
Polymer surfactants aqueous solution with polypropylene as carrier；This aqueous solution can during material molten mixes
Smell and small-molecule substance in effective absorption dissolving composite, by vacuum removal, reach by vacuum port Duan Shike
