Thermal degradation and can be different degrees of release various harmful substances, influence it in the application especially automobile interior decoration material of related fields
Material field.Improve aspect for the smell of polyester material at present, domestic and international associated specialist scholar studies existing part, main logical
The constituent content of the remaining monomer and oligomer that reduce PC/ABS polymer in the process of production and processing is crossed to control material
Smell, such as patent: CN201810481280.0 disclose it is a kind of using compound eliminating smell agent prepare low smell, it is low distribute PC/ABS close
The method of golden material, by being introduced into modified porous adsorbent come small molecule and the oligomer component in adsorpting polymerization object to realize
Low smell, the low distribution performance of PC/ABS material.Patent: CN201710133218.8, a kind of low smell PC/ABS alloy material
And preparation method thereof, by selecting the compound system of zeolite and sodium oxalate as eliminating smell agent system, existed using zeolite and oxalates
Decomposition product steam and carbon dioxide under high temperature take away the small molecule oligomer in PC/ABS melt, to realize that PC/ABS is closed
Low smell, the low distribution performance of gold.After all the method that both the above improves PC/ABS material smell is all by physico
Learn to do section to reduce the content of residual monomer and oligomer in PC/ABS material as far as possible and realize the promotion of material smell, mainly
It concentrates on to the improvement in terms of odour intensity, the type for improving material smell is not obvious, and material prepared still has plastics
Distinctive glue stink.
For the composite material of the PC/ABS class with imitative flocking effect, there is not been reported at present.The present invention passes through addition one
Kind Modified Green Tea powder functional agglomerate, using the fragrant for the natural green tea that green tea powder itself has, so that especially modified polyamides
Amine composite material has green tea fragrant, additionally due to being made using bottle-green green tea powder as filler prepared therefrom multiple
There are many dark flecks in the surface of the light colours parts such as condensation material cream-coloured or grey prepared after color matching is handled, has
The effect of similar flocking.
Summary of the invention
The present invention provides one kind and is prepared after organosiloxane is surface-treated with matrix resin by ultra-fine natural green tea powder
At modified master batch, then the modified function master batch is prepared with blending extrusions such as ABS resin, auxiliary agents.By to natural green
Tea powder carry out surface passivating treatment modification effectively improves the compatibility of green tea powder Yu PC/ABS resin, to improvement due to
Individually adding unmodified green tea powder bring material property loss has great improvement result, prepared modification PC/ABS material
Material has good mechanical property.It is prepared simultaneously because green tea powder itself has natural green tea fragrant using the composite material
Components have green tea fragrant.Additionally due to being made using bottle-green green tea powder as filler prepared therefrom compound
There are many dark flecks in the surface of the light colours parts such as material cream-coloured or grey prepared after color matching is handled, has class
Like the effect of flocking.
For up to foregoing invention purpose, the present invention is achieved through the following technical solutions:
The PC/ABS composite material of a kind of smell faint scent, imitative flocking effect is prepared by following raw material in parts by weight
It forms:
PC resin: 38~83 parts；
ABS resin: 0~40 part；
Compatilizer: 5~10 parts；
Modified Green Tea powder master batch: 10~20 parts；
The auxiliary agents such as antioxidant: 2~5 parts；
The Modified Green Tea powder master batch is prepared by following raw material in parts by weight::
Modified Green Tea powder: 70~80 parts；
ABS resin: 18~28 parts；
Auxiliary agent: 2~5 parts.
Further, the PC resin is bisphenol A-type aromatic copolycarbonate, and preferably melting means range is 5~35g/
The injection grade polycarbonate resin of 10min.
The ABS resin is the terpolymer of acrylonitrile, butadiene, styrene, the preferred ontology legal system of preparation method
Standby low smell low distributes ABS resin.
The compatilizer is PP maleic anhydride grafts, and ABS maleic anhydride grafts are one such or two kinds are combined
Object.
The Modified Green Tea powder is 90~95 parts and 5~10 parts of coating material of green tea powder, through high speed mixing preparation
At.Wherein, it is the powder that 1um to 100um is prepared through green tea smashing and grinding that the green tea powder, which is partial size,.The table
Face dressing agent is to pass through alkyl-modified organopolysiloxane.
The auxiliary agent be antioxidant 1076 (β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid n-octadecyl alcohol ester),
(three (2,4-di-tert-butyl-phenyl) phosphite esters, antioxidant DSTP (the double octadecyls of thio-2 acid), light are steady for irgasfos 168
