[0025] The preparation method of scratch-resistant high-gloss spray-free PC / ASA alloy material in the described embodiment and comparative example comprises the following steps:
[0026] S1. After mixing all the components through the mixer, feed them from the main feeding port of the twin-screw extruder;
[0027] S2. Melt extrusion and granulation to obtain scratch-resistant high-gloss PC / ASA alloy material without spraying;
[0028] A special die is added to the die of the twin-screw extruder. One end of the special die is provided with an inlet and the other end is provided with an outlet. The inlet is connected to the die of the twin-screw extruder; the diameter of the inlet is larger than the diameter of the outlet.
[0029] The barrel temperature of the twin-screw extruder is successively set to 200°C, 240°C, 260°C, 260°C, 260°C, 240°C, 240°C, 250°C, 260°C and 260°C; the screw speed of the twin-screw extruder 500-800rpm.
[0030] The length of the special die is 120mm,...

Abstract
The invention relates to a scratch-resistant high-gloss spraying-free PC/ASA alloy material and a preparation method thereof. The alloy material is prepared from, by weight, 50-70 parts of PC resin, 10-40 parts of ASA resin, 5-20 parts of a scratch-resistant agent, 0.1-1 part of a compatilizer, 0.1-1 part of an antioxidant, 0.1-1 part of a lubricant and 2-5 parts of carbon black masterbatch. The preparation method of the alloy includes the following steps that all the components are mixed through a stirrer and then fed in from a main feeding port of a twin-screw extruder; melt extrusion and granulation are performed, and the alloy is obtained, wherein a special mouth mold is additionally arranged on a mouth mold of the twin-screw extruder. According to the scratch-resistant high-gloss spraying-free PC/ASA alloy material and the preparation method thereof, with the compatilizer, the compatibility of the scratch-resistant agent and the system is improved; by introducing the special mouth mold, a strong flow field is obtained, dispersion of the scratch-resistant agent is enhanced, the problem of fogging caused by introduction of the scratch-resistant agent is solved, and the scratch-resistant high-gloss spraying-free PC/ASA alloy material is obtained.
Description
technical field [0001] The invention belongs to the fields of polymer blending and polymer molding processing, and in particular relates to a scratch-resistant, high-gloss, spray-free PC / ASA alloy material and a preparation method thereof. Background technique [0002] PC / ASA alloy materials are widely used in the fields of automobiles and electronic products due to their excellent impact resistance, heat resistance and weather resistance.
