Description
Technical field：
The present invention relates to polymer modification field more particularly to a kind of low volatilization scratch-resistant automobile interior trims of low smell
ABS composite material and preparation method.
Background technique：
Cage modle polysilsesquioxane (abbreviation POSS) is organic/nothing on the real molecular level of one kind emerging in recent years
Machine hybrid nano-material, general molecular formula are (RSiO1.5)n, n is generally 6,8,10,12 etc., wherein being 8 the most typical with n.
POSS while having the advantages of organic polymer with the nano-scale and cage structure of inorganic nano-particle, such as：
1, POSS inorganic silicon oxygen skeleton structure determines it with heat resistance outstanding, anti-flammability and radiation resistance；
2, the toughness of polymer can be improved in POSS, this is because POSS nanoparticle can terminate the hair at micro-crack tip
Exhibition, and crazing or shear band can be caused, or rearrange strand.It can root on the apex angle Si atom of POSS cagelike structure
According to needing to connect reactivity or non-reacted organo-functional group, reach and polymeric matrix reactive compatibilization or molecularly dispersed structure
Purpose, to greatly improve the performance of composite material；
3, the organo-functional group of POSS has it in nanostructure size with polymer and organic monomer compatible well
Property, while making POSS monomer be more easier to graft in polymer, therefore the unique structure of POSS and performance are that enhancing is poly-
Compound composite material, temperature tolerance, inoxidizability, anti-flammability, surface hardness and the mechanical property aspects for improving material provide
Opportunity.
ABS plays an important role in automobile component production always.Polypropylene（PP）Although after in automobile parts production
On occupying, but peerage of the ABS in high-grade car component is that PP can not shake and be completely replaced.The noble of ABS
Position be it is relevant to the good characteristic of ABS, thermoplastic ABS resin is widely recognized as being a kind of engineering material that can freely design
Material has aesthetics, flowing, toughness, dimensional stability and high-fire resistance outstanding.ABS has extensively on the interior exterior part of automobile
General application.On interior trim, ABS can be used for producing door-plate, instrument board escutcheon, glove box, middle control instrument board, air-conditioner air outlet
Deng.On exterior trim, ABS is for manufacturing heat dissipation grid, frame, license plate, decorations mark etc..With the increasingly developed of auto industry and disappear
Expense person's environmental protection and health awareness constantly enhances, and people, which do not require nothing more than car, will spacious interior space, unobscured and carriage
Comfortably, also require in-vehicle air fresh, high-quality.Interior volatile hazardous substances have attracted attention, intuitive anti-
It reflects for the perception to smell, studies have shown that the source of in-car smell is various, the volatile organic from inner-decoration component
Close object（Volatile organic compounds, referred to as " VOC "）One of the main reason for being influence in-car air quality.Greatly
All contain a certain amount of volatile organic compounds in most inner-decoration components, they are mainly alkane, alkene, aromatic hydrocarbons, amine, benzene
Phenol, mercaptan, peroxide, aldehyde, ketone substance, the boiling point of these substances is usually within the scope of 50 ~ 260 DEG C.Work as temperature
When reaching a certain height, under the action of photo-thermal, generate uncomfortable smell, or even cause headache, dry cough and allergy etc.
Discomfort reaction.On March 1st, 2012, GB/T27630-2011《Air Quality Evaluation guide in passenger car》It comes into effect, proposes
Limit value requirement to 8 kinds of substances of benzene class and aldehydes in air in vehicle compartment.Automotive upholstery is main inside automobile bodies
One of air pollution source wanted, and modified ABS be manufacture automotive upholstery one of main material, therefore prepare low smell,
Low volatile organic（8 kinds of substances of benzene class and aldehydes）Modified ABS become one new hot spot of modified plastics.In order to overcome these
Problem, the production and processing person of plastic resin is being dedicated to reducing the grade that distributes of these smells for a long time, and obtains certain
Effect.If patent CN 100580022C and 100506907 C of patent CN are using molecular sieve as adsorbent.Such as patent CN
1730542 B are using Bio-sil as adsorbent.As patent CN 103059409 using active carbon and molecular sieve compounding as
Adsorbent.It can be seen that from the above granted patent, currently as the active charcoal of material, the molecular sieve, porous silicon of volatile matter adsorbent
The materials such as glue.However the above adsorbent material always has an adsorption saturation value, and small molecule does not reach root also inside inside gadget
The purpose removed.
On the other hand, many automobile main frame maker had both required the low smell of automotive interior material, low volatile or had required in recent years
It is with good scraping and wiping resistance performance.The requirement as just having Shanghai Volkswagen.In order to both reach low smell, it is low volatilization with
And good scraping and wiping resistance performance, modified plastics producer is mainly using addition active carbon, molecular sieve or Bio-sil etc. at present
Material improves smell and volatile matter, while it is resistance to improve material that silicone substance, amide substance or polysiloxanes can be added
Scratch performance.Right silicone substance, amide substance or polysiloxanes can all bring the increase of smell and volatile matter.Such as patent CN
102329459 A using silicone or polysiloxanes as scratch resistance liniment, using fatty acid lipoid substance, nano zine oxide,
Nano-titanium oxide is as odor adsorption agent, but the smell of last composite material and scraping and wiping resistance performance are general.Such as patent CN
102532710 A are using nano silicon oxide as scratch resistance liniment, using porous silica or zeolite as odor adsorption agent, but most
The smell of composite material and scraping and wiping resistance performance are general afterwards.The present invention is utilized except volatile substance master batch is poly- by foaming in process
Liquid in styrene is vaporizated into steam and it is partially or completely discharged by double vacuum for the volatile small molecule in material, with
Reach the volatile materials and odoriferous substance eradicated in material.On the other hand POSS material is added and is remarkably improved composite material
Scraping and wiping resistance performance, and smell and volatile substance will not be brought.
