Problems solved by technology

This performance has always been the short board of the brominated flame-retardant ABS material system, which usually can only reach between 700-725°C, which severely limits the application of flame-retardant ABS materials in live parts such as heater shells and switch parts shells. The safety standards of the plastic materials used usually require a temperature of 775°C or higher
At present, non-alloy flame retardant ABS system, GWIT can reach above 775 ℃, there are no reports in patents and literature

[0064] The raw materials and parts by weight of the ABS composite materials are shown in Table 1.

[0065] The preparation methods are:

[0066] Weigh the materials according to the parts by weight, put them into the mixer and mix them for 5 minutes at a speed of 1000 rpm, take them out, put the mixed materials into the feed hopper of the twin-screw extruder, and follow the set process, including extruding The temperature setting range of each section of the machine is 180°C, 220°C, 240°C, 240°C, 240°C, 240°C, 240°C, 240°C, 240°C, 240°C. The screw speed setting range is 350 rpm, After melting and blending through a co-rotating twin-screw extruder, water-cooled strands are cut into pellets to obtain ABS composite material particles.

Abstract

The present invention relates to an ABS composite material and a preparation method thereof, the ABS composite material comprises the following raw materials in percentage by weight: 37-79% of ABS resin; 15-25% of a flame retardant; 5-20% of a filler; 0-10% of a toughening agent; and 1.0-8% of an auxiliary agent. The GWIT of the obtained ABS composite material can be larger than 775 DEG C, the stability is good, the safety requirement is met, and application of the flame-retardant ABS material to the periphery of a fan heater and the periphery of an electrified part can be unlocked.

Description

technical field [0001] The invention belongs to the field of engineering plastic composite materials and preparation thereof, in particular to an ABS composite material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer resin, that is, ABS resin, its performance is between engineering plastics and general-purpose plastics, with excellent comprehensive mechanical properties and processing and molding properties, it is widely used in many fields such as electronics, machinery, and construction Applications. However, limited by its polymer structure and composition, ABS resin also has many defects and deficiencies, such as no wear resistance, low heat resistance, poor weather resistance, and can only achieve HB level flame retardancy. [0003] Using ABS resin as the matrix, adding a certain amount and ratio of brominated flame retardants and antimony-containing compound flame retardant synergists can prepare flame retardan...
