Example Embodiment
[0041] Example 1
[0042] The scratch-resistant resin with excellent appearance properties is prepared according to the following components:
[0043] (1) Preparation of ASA cross-linked modified graft copolymer:
[0044] ASA rubber powder 50 copies
[0045] SAN resin 40 parts
[0046] 10 parts of third polymer
[0047] Initiator 0.8 parts
[0048] Antioxidant 0.3 parts
[0049] Lubricant 0.5 parts
[0050] Among them, ASA rubber powder is Korea Kumho;
[0051] The SAN resin is Zhenjiang Chimei SAN D168;
[0052] The third polymer is polycarbonate;
[0053] Initiator: BPO;
[0054] The lubricant is PETS;
[0055] Antioxidant is B900;
[0056] (1) After mixing ASA rubber powder, SAN resin, third polymer, initiator, antioxidant, and lubricant in a high-speed mixer, they are fed into a twin-screw extruder through a metering device to control the double-screw extruder. The temperature of the screw extruder is 180~220℃, the screw length-to-diameter ratio is 40, and the screw speed is 300rpm. Under th...
