Temperature mixing 15min, is then transferred to sealing and standing 5h in -15 DEG C of environment, and granularity finally is made less than 0.15mm's using pulverizer
Particle, produce chliorinated polyvinyl chloride/asbestos wool.
The chliorinated polyvinyl chloride, asbestos wool, double trifluoromethanesulfonimide silver salt, polyoxyl 40 hydrogenated castor oil
Mass ratio is in 10-20:1-5:0.05-0.2:0.5-2.
The sepiolite powder passes through modification before using, and its specific method of modifying is：Tissuemat E is heated to melting
State insulation mixing 5min, adds sepiolite powder and PVPP, is sufficiently mixed after microwave frequency 2450MHz, output
Microwave treatment 5min, is well mixed again under power 700W, continues microwave treatment 5min, and gained mixture naturally cools to room
Temperature, micro mist most is made through micronizer afterwards.
The Tissuemat E, sepiolite powder, the mass ratio of PVPP are in 0.5-2:5-10:0.5-2.
The beneficial effects of the invention are as follows：The made anti-impact modifier of the present invention is applied to the processing of notebook computer casing,
The anti-impact modifier and notebook computer casing, which mainly process raw material, has good comixing compatibility between ABS and PC, and
The blending for effectively facilitating raw material is compatible；And the anti-impact modifier is remarkably improved when its quality addition is 2.5%
The impact resistance of made notebook computer casing, therefore can play and be sent as an envoy to outside made notebook computer on the basis of its low dosage
Shell has the impact of performance of excellent impact resistance.
