Embodiment Construction

[0016] The technical scheme of the present invention will be further described below in conjunction with specific examples:

[0017] A kind of preparation method of flame-retardant ABS alloy is characterized in that, comprises the following steps:

[0018] (1) Add ABS resin, nano-calcium carbonate, flame retardant, zinc stearate, and silicone oil into the high-mixer at a mass ratio of 80:6:5:1:0.4 and mix;

[0019] (2) Put the above-mentioned uniformly mixed raw materials into a twin-screw granulator, and extrude and granulate under vacuum; the barrel temperature of the twin-screw granulator is controlled between 230-260°C, and the vacuum degree is - 0.08~-0.12MPa, the speed is 45-55Hz.

[0020] (3) Air-cool the extruded material, dry it, and cut it into pellets. The drying temperature of the material is 80-100°C, and the time is 15-30 minutes. That is, the flame-retardant ABS alloy of the present invention is obtained.

[0021] The preparation method of flame retardant:

Abstract

The invention discloses a preparation method of a flame-retardant ABS alloy. The preparation method comprises the following steps that (1) ABS resin, nano calcium carbonate, a flame retardant, zinc stearate and silicone oil are jointly added to a high-speed mixer for mixing; (2) the uniformly mixed raw materials are transferred into a twin-screw granulator, and extrusion granulation is performed under the vacuum condition; and (3) the extruded material is air-cooled, dried and pelletized to obtain the flame-retardant ABS alloy. According to the preparation method of the flame-retardant ABS alloy, the overall flame retardance of the ABS material can be significantly improved, and the obtained flame-retardant ABS alloy not only has good flame retardant performance, but also has ideal mechanical strength and higher use value, and is suitable for factory scale production.

Description

technical field [0001] The invention belongs to the technical field of composite materials, in particular to a method for preparing a flame-retardant ABS alloy. Background technique [0002] ABS material is the abbreviation of acrylonitrile-butadiene-styrene copolymer. It is a thermoplastic polymer material with high strength and easy processing.
