Description
Technical field
The present invention relates to a kind of functionality polyamide class material and preparation method thereof more particularly to a kind of smell faint scent, imitate
The polyamide functional agglomerate of flocking effect and its preparation method of composite material, belong to polyamide technical field.
Background technique
Polyamide polymer has the advantages that good mechanical performance, intensity is high, and heat resistance is good and is widely used in
The various fields such as automobile, machinery, chemical industry, electronics.But conventional polyamide material after high-temperature fusion squeezes out due to dividing greatly
The thermal degradation of subchain section and cause parts product smell prepared therefrom poor, influence it in the application of related fields, especially
The fields such as automotive interior material, indoor furniture material.The smell for being directed to polyester material at present improves aspect, related special both at home and abroad
Family scholar studies existing part, is concentrated mainly on following two mode, first, being produced and processed by reducing polyamide polymer
The constituent content of remaining monomer and oligomer form in the process controls material smell, such as patent:
CN201711021323.9 discloses a kind of low smell daiamid composition and preparation method thereof, passes through and introduces phosphoric acid salt antioxygen
Agent can be such that the impurity for leading to polyamide material catalytic degradation inactivates, reduce polyamide in process of production remaining monomer and
Oligomer, so that realizing reduces material smell.Second, being produced by introducing odor adsorption agent to adsorb polyamide
Remaining monomer and oligomer in journey, thus realize the smell of control polymer material, such as patent:
CN201510973763.9, disclose it is a kind of it is low distribute, high heat resistance polyamide compoiste material and preparation method thereof, it is attached by adding
Agent mantoquita type thermal stabilizing agent in conjunction with the composition of molecular sieve realizes low smell, the low distribution performance of polyamide material.Gui Gen
Knot bottom both the above improve polyamide material smell method be all reduced as far as possible by physical chemistry means it is residual in material
The content of monomer and oligomer is stayed to realize the promotion of material smell, is concentrated mainly on to the improvement in terms of odour intensity, improves
The type of material smell is not obvious, and material prepared still has the distinctive glue stink of plastics.
For the polyamide-based composite material 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 provide it is a kind of after being had polyethylene glycol (PEG) surface treatment by ultra-fine natural green tea powder with polyether ester
(PET-PEG) resin is prepared into modified master batch, then by the blending extrusions system such as the modified function master batch and polyamide, auxiliary agent
It is standby.By carrying out the modified phase for effectively improving green tea powder with polyamide of surface treatment to natural green tea powder
Capacitive has great improvement result due to individually adding unmodified green tea powder bring performance loss to improving, prepared
Modified polyamide material has good mechanical property.To adopt simultaneously because green tea powder itself has natural green tea fragrant
There is green tea fragrant with components prepared by the composite material.Additionally due to being made using bottle-green green tea powder as filler
The surface for obtaining the light colours parts such as composite material prepared therefrom cream-coloured or grey prepared after color matching is handled occurs very much
Dark fleck has the effect of similar flocking.
For up to foregoing invention purpose, the present invention is achieved through the following technical solutions:
A kind of polyamides implant of smell faint scent, imitative flocking effect, it is characterised in that: including it is following by weight

The Modified Green Tea powder is 90~95 parts and 5~10 parts of surface treating agent of green tea powder, through high speed mixing preparation
At.The green tea that the green tea powder partial size is 1um to 100um carries out surface through polyethylene glycol (PEG) again after smashing and grinding
Activation modification is prepared.The surface treating agent is selected from the polyethyleneglycol resins that molecular weight is 6000 to 10000.
The auxiliary agent be antioxidant 1076 (β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid n-octadecyl alcohol ester),
Irgasfos 168 is (in three (2,4-di-tert-butyl-phenyl) phosphite esters, antioxidant DSTP (the double octadecyls of thio-2 acid)
One or several kinds of mixtures.
The polyetherester resins (PET-PEG) are the copolymer of polyethylene terephthalate and polyethylene glycol,
Middle polyether component content is not less than 60wt%.
It can also include that those skilled in the art think other addible auxiliary agents, such as toner in above-mentioned composite material.
