Embodiment Construction

[0032] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention will be further described below with reference to specific embodiments.

[0033] The preparation method of ABS composite material in the embodiment of the present invention is:

[0034] The components are uniformly mixed in a high-speed stirring mixer to obtain a premix; the premix is ​​fed into a twin-screw extruder, extruded, cooled with water, and pelletized to obtain a flame-retardant ABS composition; The temperature of each section of the screw extruder from the feeding port to the die head is 80°C in the first zone, 160°C in the second zone, 180°C in the third zone, 190°C in the fourth zone, 190°C in the fifth zone and 190°C in the sixth zone. The temperature of the zone is 190°C, the temperature of the seventh zone is 180°C, the temperature of the eight zone is 180°C, the temperature of the nine zone is 180°C, the head temperature is 200°C...

Abstract

The invention discloses a flame-retardant ABS composition, which comprises the following ingredients in parts by weight: 36.2-82.7 parts of ABS resin, 12-20 parts of brominated flame retardant, 3-10 parts of antimony-based flame retardant and 0.2 parts of processing aid ~0.8 parts; in the total weight of the flame-retardant ABS composition, the content of nitrogen element is not more than 85000ppm and not less than 7000ppm, the total content of phosphorus element is not more than 50000ppm and not less than 3000ppm, the total content of fluorine element is not more than 40000ppm and not Less than 800ppm. This application uses a variety of flame retardant systems for compound synergy, and under the joint action of various flame retardant elements, a higher glow wire performance is achieved. At the same time, the invention also provides a preparation method of the flame-retardant ABS composition.

Description

technical field [0001] The invention belongs to the technical field of ABS composite materials, and in particular relates to a flame-retardant ABS composition and a preparation method thereof. Background technique [0002] ABS materials are often used as casings for electrical and electronic products. These products will cause fires due to overheating, leakage, and aging of these materials, posing a huge threat to people's lives and property safety. The industry's safety standards and standards consistently implement the UL94 standard to evaluate the flame retardant safety of polymer materials due to passive ignition, such as V-2, V-1 and V-0 flame retardant grades. In the case of overheating due to poor contact, overload and short circuit during use, the EU International Electrotechnical Association IE C60695 glow wire standard is used to evaluate its flame retardancy and safety. [0003] The chemical structure of ABS terpolymer contains polybutadiene rubber components, wh...
