Example Embodiment
[0043] The preparation steps of the matte masterbatch are as follows:
[0044] Weigh the components according to the matte masterbatch formula in Table 1; put the weighed high-impact polystyrene, toughening agent, compatibilizer, and antioxidant into a high-speed mixer and mix for 5-30 minutes, and then out The obtained mixture is extruded and pelletized by a twin-screw extruder, the temperature of the twin-screw extruder is 180-210°C, the screw speed is 180-600 rpm, and the vacuum degree is greater than 0.09 MPa.
Example Embodiment
[0045] Example 1-6
[0046] Examples 1-6 provide a low-gloss heat-resistant ABS resin composition, the components and parts by weight are shown in Table 3.
[0047] The preparation method of the low-gloss heat-resistant ABS resin composition includes the following steps:
[0048] Weigh the components according to the low-gloss heat-resistant ABS resin formula in Table 3; put the weighed ABS, matte masterbatch, heat-resistant agent and additives into a high-speed mixer and mix for 5-30 minutes, and then discharge the mixture to obtain the mixture The obtained mixture is extruded and pelletized by a twin-screw extruder, the temperature of the twin-screw extruder is 180-240°C, the screw speed is 180-600 rpm, and the vacuum degree is greater than 0.09MPa.
