[0066] Examples 1-12 and Comparative Examples 1-8: Preparation of Flame Retardant ABS Composition

[0067] Sulfur-containing compounds, phosphorus-containing compounds and silicone oil are formulated into a silicone oil solution with a mass fraction of 25ppm-2500ppm; tin-containing compounds and silicone oil are formulated into a silicone oil solution with a mass fraction of 20ppm-3500ppm; the two silicone oil solutions obtained above are mixed with the ABS, flame retardant, and processing aid are uniformly mixed in a high-speed mixing mixer according to the ratio in Table 1 to obtain a premix; the above premix is ​​sent into a twin-screw extruder, extruded, and cooled by water. The flame-retardant ABS composition is obtained by granulation; wherein, the temperature of each section of the screw of the twin-screw extruder from the feed port to the machine head is preferably 80°C in the first zone, 160°C in the second zone, and 180°C in the third zone. The temperature of the fou...

Abstract

The invention discloses flame-retardant ABS composition. The composition is prepared from the components of, by weight, 40-83 parts of ABS, 11-50 parts of fire retardant, 0-10 parts of processing agent. According to the composition and the preparation method thereof, it is selected that the content of the tin element in a formula of the flame-retardanat ABS composition is smaller than or equal to 3000ppm and larger than or equal to 10ppm, and the compounding total of the sulphur element and the phosphorus element is smaller than or equal to 2100ppm and larger than or equal to 10ppm. The composition has outstanding thermal stability and flame retardancy, and is capable of overcoming material appearance defects and maintaining good mechanical performance and particularly applicable to places where product molds are complex and pin-point gate cutting is serious.

Description

technical field [0001] The invention relates to a flame-retardant ABS composition, in particular to a flame-retardant ABS composition with excellent thermal stability and flame retardancy, a preparation method and application thereof. Background technique [0002] ABS resin is a terpolymer composed of styrene, butadiene and acrylonitrile. It has the high fluidity of styrene, the toughness of butadiene and the chemical corrosion resistance of acrylonitrile. It has excellent processing performance, resistance Low temperature performance, electrical insulation performance, high gloss and excellent electroplating performance, as well as good creep resistance, high dimensional stability, small molding shrinkage, etc. widely. [0003] When ABS is used in an environment that requires flame retardancy, because its oxygen index is only 18, it cannot achieve the effect of flame retardancy. Although we can endow ABS with good flame retardancy by adding a halogen flame retardant, it i...
