Description
Technical field
The present invention relates to a kind of PA66/ tremolite/MBS composite and preparation method thereof.
Background technology
PA66 is a kind of crystalline polymer, has excellent combination property as engineering plastics, is widely used in vapour
The aspects such as car, electronics, electrical equipment, mechanical part, transportation equipment.But the thermostability of PA66 and acid resistance are poor, in dry state and
Under low temperature, impact strength is on the low side；Water absorption rate, molding shrinkage is relatively big, affects product size stability and electrical property.Poly-for being suitable for
Amide is in the development of different field, and this just requires that polyamide has higher mechanical strength, heat resistance.Mechanical part, railway
Locomotive is equal mechanical properties to PA66 with polyamide, and dimensional stability proposes the highest requirement.Therefore, the modified beginning to nylon
In certainty, use block, be grafted, be blended, the modification technology such as filling and technique are paid close attention to and are developed so that it is to multi-functional
Exhibition.
Use Inorganic Fillers Filled modification can improve some performances and reduce cost.But research shows, adds in PA66
When entering rigid particles, generally while improving material stiffness, reducing the toughness of material, loading is the highest, and its effect is the most aobvious
Write；Use elastic body toughening PA66 in other occasion, make material improve toughness, improve low temperature impact properties, but
The rigidity making material declines.For balance-impact performance and rigidity, improve the combination property of material and reduce cost, can use
The way that PA66-elastomer-rigid body tertiary blending is compound.To obtain reinforced and toughened PA66 engineering plastics so that it is expand at certain
The range of application in a little fields.
In PA66 toughened system, the factor affecting toughness raising is a lot, but toughener phase particularly toughener particle
Size and and matrix between the compatibility be main influence factor.By prepared by emulsion polymerisation process, there is " core-shell structure copolymer "
The toughener of structure has the strongest toughening effect to PA66.Owing to the particle diameter of this toughener controls the most
In suitable scope, not affected by blending technology during melt blending, it is easier to realize list in polymeric matrix
Dispersed and distributed, thus be conducive to obtaining preferable toughening effect.In the present invention, we are respectively adopted the methyl of " core-shell structure copolymer " structure
Acrylate-styrene-butadiene copolymer (MBS) carrys out toughened PA 66, and standard is done in the preparation for high-strength ultra-tough PA66 complex
Standby.It addition, use bisphenol A-type solid epoxy (DGEBA) as the bulking agent between toughener and matrix resin.In order to make up
Add toughener and cause the decline of system rigidity and intensity, PA66 toughened system adds the tremolite of modification as enhancing
Agent, to improve intensity and the rigidity of co-mixing system, finally makes complex have optimal toughness and rigidity.
Summary of the invention
The present invention solves that above-mentioned technical problem employed technical scheme comprise that a kind of PA66/ tremolite/MBS of offer is combined
Material and preparation method thereof, wherein the specific scheme is that
Use PA66, the tremolite, MBS, bisphenol A type epoxy resin, resist
Oxygen agent, lubricant are made.
The above-mentioned a kind of PA66/ tremolite/MBS composite, wherein tremolite granule has higher whiteness and attachment
Power, as a kind of new inorganic filler, has certain application in terms of pottery, papermaking and coatings industry, and price is low
Honest and clean, aboundresources.
Specific as follows in above-mentioned middle tremolite organic modification step: in 2000ml there-necked flask, anhydrous with 1200ml
Ethanol dispersion 500g tremolite sample, adding 60ml concentration is 25% ammonia.Flask is placed in 45 DEG C of water-bath mechanical agitation
After 500min, in 2h, it is slowly added dropwise the mixed solution of 20ml MPS and 80ml dehydrated alcohol.After completion of dropwise addition, continue stirring
24h.Stand one week.Post processing: major part solvent and ammonia are evaporated off with Rotary Evaporators normal pressure, by follow-up filtration washing,
Remove unnecessary unreacted MPS.After dry, grind, sieve, it is thus achieved that the modified tremolite.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
Reinforced and toughened PA66, its constituent and weight ratio are as follows:
The viscosity number of above-mentioned PA66 is between 100-200；Described toughener is methyl methacrylate-butadiene-benzene second
Alkene copolymer or their compound；Described tremolite specification is 1250 mesh；Described lubricant is that calcium stearate or ethylene are double hard
Acyl amine or their compound；Described antioxidant is 1010, and described compatilizer is bisphenol A type epoxy resin.
The above-mentioned a kind of PA66/ tremolite/MBS composite and preparation method thereof, it the specific scheme is that
Prepared by the first step, tremolite modification: disperse tremolite sample with dehydrated alcohol, add ammonia.Flask is placed in
After water-bath mechanical agitation, it is slowly added dropwise the mixing of γ-methacryloxypropyl trimethoxy silane (MPS) and dehydrated alcohol
Solution.After completion of dropwise addition, continue stirring and stand again.Post processing: normal pressure is evaporated off major part solvent and ammonia, by follow-up filtration
Washing, removes unnecessary unreacted MPS.
Second step, above material is blended, double screw extruder carries out extruding pelletization, obtain high-performance engineering and mould
Material alloy material (the PA66/ tremolite/MBS) particle；
3rd step, then carry out test piece injection mo(u)lding with injection machine according to standard gauge provisioning request, use ability meter pair
It carries out the detection of correlated performance, the most qualified to confirm the performance of material.
The present invention has the advantages that relative to prior art
The raw material that this technology is used, is blended and joins performance complement by force, and processing technology is excellent, can be by blended, spiral shell
Bar extrusion, injection mo(u)lding, obtain the PA66/ tremolite/MBS alloy product that combination property is superior.
