Embodiment 1

[0008] Embodiment 1, ABS resin powder (82%, percent by weight, hereinafter the same) and tricresyl phosphate (0.5%) are added in the high-speed mixer, open the high-speed mixer, stop the high-speed mixer after mixing for 10 minutes, and then Add antioxidant 168 (0.5%), antioxidant 1010 (0.5%), Nano-SiO 2 (3%), magnesium stearate (0.5%), polycarbonate resin (PC) (5%) and polyurethane resin (8%), close the high-speed mixer, then start the high-speed mixer, and mix the materials for 10min Then release and send into the hopper of the twin-screw extruder, turn on the twin-screw extruder, control the rotating speed to 230r / min, and control the temperatures of the front, middle, rear and head of the barrel to 200-205 ℃, 210~215℃, 200~205℃, 210~220℃, the material extruded from the extruder is water-cooled, pelletized, sieved, dried and packaged to become a high-toughness heat-resistant ABS resin.

Embodiment 2

[0009] Embodiment 2, ABS resin powder (85%, percent by weight, hereinafter the same) and tricresyl phosphate (0.5%) are added in the high-speed mixer, open the high-speed mixer, stop the high-speed mixer after mixing for 10min, and then Add Antioxidant 168 (0.3%), Antioxidant 1010 (0.3%), Nano-SiO 2 (2.5%), magnesium stearate (0.4%), polycarbonate resin (PC) (3%) and polyurethane resin (8%), close the high-speed mixer, then start the high-speed mixer, and mix the material for 10min After that, it is released and sent into the hopper of the twin-screw extruder, the twin-screw extruder is turned on, its rotating speed is controlled to be 250r / min, and the temperatures of the front, middle, rear and head of the barrel are controlled to be 200~ 205°C, 210-215°C, 200-205°C, 210-220°C, the material extruded from the extruder is water-cooled, pelletized, sieved, dried, and packaged to become high-toughness heat-resistant ABS resin.

Abstract

The invention belongs to the technical field of chemical industry and relates to a production formula of a high-toughness heat-resisting ABS resin and a preparation method thereof, the formula comprises ABS resin powder, antioxidant 168, antioxidant 1010, tritolyl phosphate, magnesium stearate, nano-silicon dioxide (Nano-SiO2), polycarbonate resin (PC) and polyurethane resin. The preparation method according to the invention comprises the steps: uniformly mixing the ABS resin powder and the tritolyl phosphate in a high-speed mixer, sequentially adding the rest materials in the formula into the high-speed mixer, uniformly mixing and then feeding the materials into a double screw extruder, and obtaining the high-toughness heat-resisting ABS resin by water-cooling, granulating, sieving, drying and packaging the materials extruded out of the double screw extruder. The resin has the characteristics of good heat resistance, high impact strength, excellent toughness and low production cost.

Description

Technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a production formula of high-toughness heat-resistant ABS resin and a production method thereof. Background technique [0002] At present, the heat-resistant ABS resin on the market is mainly imported, and the domestic heat-resistant ABS resin has the defects of low heat resistance and toughness. In addition, it also has the problems of high production cost and high product selling price. The price of imported heat-resistant ABS resin is much higher than that of domestic heat-resistant ABS resin, and its heat distortion temperature is limited to about 105°C, and its impact strength is 20kj / m 2 about. Invention content: [0003] The object of the present invention is to provide a production formula and a production method of a high-toughness heat-resistant ABS resin with good heat resistance and toughness, high tensile strength and impact strength, and low production c...
