Description
Technical field
The present invention relates to macromolecule modified Material Field, more particularly to a kind of bloom, resist wear-resisting scuffing PMMA compositions and
Its preparation method.
Background technology
Polymethyl methacrylate（PMMA）, it is polymerized by methyl methacrylate monomer, it is good, resistance to mechanical strength
Soda acid, resistance to water-soluble inorganic salt, alkane and grease, surface gloss, the advantages of hardness is high, but itself there is also poor fluidity,
The defect such as impact strength is low, surface is easily scratched, worn no resistance.
Current automobile exterior material, which often use, to be contained ABS in PC alloys, such as PC/ABS, PC/ASA, PC/ABS alloys its is weather-proof
Poor-performing, it is impossible to be directly used in air, it usually needs be surface-treated（Spray painting, plating etc.）, but no matter
Be spray painting or electroplate except because increase process cause cost increase, it is important to it is very unfriendly to environment.PC/ASA alloys
With good weatherability, but a disadvantage is that case hardness is poor, and the inadequate bloom in surface.
Chinese patent CN101805505A discloses a kind of PC/PMMA alloys and preparation method thereof, be prepared for a kind of bloom,
High hardness material, but molding processibility is poor, its application is restricted very much, it is impossible to meet the requirement of automobile component.
Chinese patent CN104672759A discloses a kind of Gao Gang, anti-impact, damage resistant ABS/PMMA/PETG alloys and its system

1）It is 3 ~ 4h of drying process at 90 ~ 100 DEG C that PMMA resins first are placed in into temperature, stand-by；
2）Dry PMMA resins, anti-wear agent, toughener, compatilizer, lubricant and antioxidant are weighed based on material quality part together
After 3 ~ 15min of stirring is well mixed, discharging is added in double screw extruder, is fully plastified by double screw extruder crowded after blending
Go out, cooling granulation, produce PMMA composition finished products.
As the further improvement of such scheme, the technological parameter of the double screw extruder is：1 200 ~ 220 DEG C of area, 2
200 ~ 220 DEG C of area, 3 205 ~ 230 DEG C of areas, 4 205 ~ 230 DEG C of areas, 5 210 ~ 230 DEG C of areas, 6 210 ~ 230 DEG C of areas, 7 areas 210 ~
230 DEG C, 8 210 ~ 230 DEG C of areas, 9 210 ~ 230 DEG C of areas, 10 210 ~ 230 DEG C of areas, 230 ~ 250 DEG C of head temperature, head pressure is
3.8MPa, main frame electric current is 30Hz, and vacuum is -0.06MPa.
The beneficial effects of the invention are as follows：Although traditional PMMA materials have bloom, high rigidity, its impact strength
Low, addition toughener can improve its toughness, but case hardness and wearability are deteriorated, and it can not have bloom, high rigidity concurrently all the time
And excellent mechanical property.The present invention in PMMA resins by adding anti-wear agent, and it is dispersed in PMMA resins, in table
Face forms a kind of fine and close top layer, effectively improves the case hardness and anti-wear performance of PMMA resins.Add simultaneously in the present invention
Add a kind of preferred ethylene-acrylic acid copolymer lubricant, with reference to POM self-lubricating function, effectively reduce PMMA resins
