preparation example Construction
[0034] The application also provides a method for preparing a lampshade, comprising the steps of:
[0035] S101: uniformly mixing each component material to obtain a mixed material;
[0036] According to the ratio (for example: when the composition material of the lampshade includes polymethyl methacrylate (PMMA), ABS resin, toughening agent, compatibilizer, light diffusing agent and antioxidant, wherein, polymethyl methacrylate (PMMA), ABS resin, toughening agent, compatibilizer and light diffusing agent are respectively by weight percent: polymethyl methacrylate (PMMA) 70-80%, ABS resin 5-10%, toughening agent 3- 8%, compatibilizer 3-6%, light diffusion agent 4-9%; said antioxidant and said polymethyl methacrylate (PMMA), ABS resin, toughening agent, compatibilizer, light diffusion The weight ratio of the total weight of the agent is (0.002-0.004): 1) Add each component material into the material mixing tank, so that each component material is mixed evenly. In the actual s...
example 1
[0047] Add 70 parts of PMMA resin, 10 parts of ABS resin, 8 parts of toughening agent MDA, 8 parts of light diffusing agent, 4 parts of compatibilizer SMA, and 0.3 parts of antioxidant into a high-speed mixing tank to make it evenly mixed; then, put The homogeneously mixed mixture is fed into a twin-screw extruder, and the temperatures of each section of the twin-screw are: T1=220°C, T2=230°C, T3=240°C, T4=245°C, T5=250°C, T6= 250°C, the rotational speed of the twin-screw extruder is 320rpm; after being extruded by the twin-screw extruder, it is cooled and pelletized to obtain a tough material. Add the pelletized tough material to the single-screw extruder. The temperature of each section of the single-screw extruder is 215-235°C from the first section to the seventh section, and 215-235°C from the seventh section to the twelfth section. 240-250°C; the rotational speed of the single-screw sheet extruder is 60-70rpm; extruded by the single-screw sheet extruder to obtain a tough...

[0049] Add 75 parts of PMMA resin, 5 parts of ABS resin, 8 parts of toughening agent MDA, 8 parts of light diffusing agent, 4 parts of compatibilizer SMA, and 0.3 part of antioxidant into a high-speed mixing tank to mix evenly; then, put The homogeneously mixed mixture is fed into a twin-screw extruder, and the temperatures of each section of the twin-screw are: T1=220°C, T2=230°C, T3=240°C, T4=245°C, T5=250°C, T6= 250°C, the rotational speed of the twin-screw extruder is 320rpm; after being extruded by the twin-screw extruder, it is cooled and pelletized to obtain a tough material. Add the pelletized tough material to the single-screw extruder. The temperature of each section of the single-screw extruder is 215-235°C from the first section to the seventh section, and 215-235°C from the seventh section to the twelfth section. 240-250°C; the rotational speed of the single-screw sheet extruder is 60-70rpm; extruded by the single-screw sheet extruder to obtain a tough sheet.
