Embodiment Construction

[0025] Table 1 Raw material composition distribution ratio

[0026]

[0027]

[0028] The parts by weight of each raw material are shown in Table 1

[0029] 1) Add ABS resin and various additives into the high-speed mixer and stir for 2 minutes at high speed.

[0030] 2) Add to the main feeder of the extruder,

[0031] 3) Then add it to a twin-screw extruder for basic granulation. The temperature distribution of the extruder is as follows: from the feed section to the head: 180°C, 200°C, 200°C, 200°C, 190°C, 190°C, 190°C, 180°C, 180°C, die head: 190°C ,

[0032] 4) After the material is extruded, it is water-cooled, pelletized, and then packed. The pellets were dried in a blast oven at 100°C for 4 hours, and then test specimens were prepared by an injection molding machine.

Abstract

The invention discloses a high heat-resistant low-smoke flame-retardant ABS material. The high heat-resistant low-smoke flame-retardant ABS material is composed of the following components in percentage by mass: 58-80% of ABS resin, 8%-20% of brominated flame retardant, 3%-10% of stibium flame retardant, 1-2% of a compound smoke suppressor, 1%-5% of an inorganic flame-retardant synergist, 0.1-1.0% of an anti-dripping agent and 1%-5% of other processing aids. The invention further provides the preparation method of the high heat-resistant low-smoke flame-retardant ABS material. The ABS resin is used as a matrix to prepare the high heat-resistant low-smoke flame-retardant ABS material through the smart combination of the flame retardant, the smoke suppressor and the special processing aids. The high heat-resistant low-smoke flame-retardant ABS material can be widely applied to the communication industry, the automobile industry, building materials, decorative materials, cables and the electric appliance industry.

Description

Technical field: [0001] The invention belongs to the field of chemical industry, and in particular relates to an ABS material, in particular to a high-heat-resistant, low-smoke, flame-retardant ABS material and a preparation method thereof. Background technique: [0002] Acrylonitrile-butadiene-styrene copolymer English name: Acrylonitrile butadiene Styrene copolymers, ABS for short. ABS is a thermoplastic polymer material structure with high strength, good toughness and easy processing. In ABS resin, the synergistic properties between the three components can be exhibited: the properties of acrylonitrile component in ABS are heat resistance, chemical resistance, rigidity, and tensile strength, and the properties of butadiene are impact resistance Strength, styrene is characterized by processing fluidity and gloss. The combination of these three components complement each other, so that ABS resin has excellent comprehensive performance, good rigidity, high impact strength,...
