Embodiment 1

[0027] 35KgABS rubber powder, 45KgAS resin, terpolymer of 15KgN-phenylmaleimide, maleic anhydride and styrene, 5Kg acrylic copolymer, 0.1Kg bisphenol A, 0.1Kg IG-168 were added to After stirring in a high-speed mixer for 20 minutes, the material is discharged, and then extruded and granulated in a twin-screw extruder with an aspect ratio of 36 and a diameter of 35 mm. The barrel temperature of the extruder is 180-280 ° C, and the screw speed is 180-600rpm.

Embodiment 2

[0029] In order to better reflect the characteristics of the above-mentioned heat-resistant ABS resin composition for blow molding, and to compare the influence of different heat-resistant agent dosages on product performance, Example 2 is used here. In this embodiment, the terpolymer of N-phenylmaleimide identical with embodiment 1 and maleic anhydride and styrene is selected as the heat resistant agent, and the addition is changed from 15 parts in embodiment 1 to It is 5 parts, and the specific production is as follows: 35KgABS rubber powder, 55KgAS resin, 5KgN-phenylmaleimide, maleic anhydride and styrene terpolymer, 5Kg acrylic copolymer, 0.1Kg bisphenol A, 0.1Kg IG-168, join in the high-speed mixer and stir for 20 minutes and discharge, then extrude and granulate in a twin-screw extruder with a length-to-diameter ratio of 36 and a diameter of 35mm. The barrel temperature of the extruder is 180-280°C, the screw speed is 180-600rpm.

Embodiment 3

[0031] In order to better reflect the characteristics of the above-mentioned heat-resistant ABS resin composition for blow molding, and to compare the effects of different amounts of heat-resistant agents, Example 3 is used here. In this embodiment, the terpolymer of N-phenylmaleimide identical with embodiment 1 and maleic anhydride and styrene is selected as the heat resistant agent, and the addition is changed from 15 parts in embodiment 1 to 25, the specific production is as follows: 35KgABS rubber powder, 35KgAS resin, 25KgN-phenylmaleimide, maleic anhydride and styrene terpolymer, 5Kg acrylic copolymer, 0.1Kg bisphenol A, 0.1 Kg IG-168, added to the high-speed mixer and stirred for 20 minutes, then discharged, then extruded and pelletized in a twin-screw extruder with a length-to-diameter ratio of 36 and a diameter of 35mm. The barrel temperature of the extruder was 180 -280°C, the screw speed is 180-600rpm.

Abstract

The invention discloses a heat-proof ABS resin compound for blow molding formation and a preparation process thereof. The ABS resin compound is adopts ABS rubber powder with high molecular weight and appropriate rubber content, AS resin with high molecular weight, heat resisting agent with appropriate thermal deformation temperature, is matched with toughening agent with high molecular weight and other auxiliary agent, and is prepared through fusion, commixture and extrusion in a twin-screw extruder. The ABS resin compound has high flux strength, impact property and tension property, which is especially suitable for containers with large size and blow molding shape of car tail wings.

Description

technical field [0001] The invention relates to a heat-resistant ABS resin composition for blow molding and a preparation method thereof, in particular to an ABS resin composition which can be used for blow molding various large-sized containers and tail fins of automobiles. technical background [0002] At present, ABS resin has been widely used in electronic / electrical equipment and auto parts. ABS resins used in electronic / electrical equipment and auto parts must have high heat resistance in addition to good mechanical properties, while heat-resistant ABS resin compositions suitable for blow molding must have high melt Strength, impact resistance and tensile properties. Generally, heat-resistant ABS resin requires high processing temperature, and when the processing temperature rises, the fluidity increases and the melt strength decreases, which is not good for wall hanging during blow molding; if the processing temperature is lowered, it is not conducive to the uniform ...
