High-fluidity, high-flame-retardancy and high-toughness ABS (Acrylonitrile-Butadiene-Styrene) and preparation method thereof

Abstract

The invention discloses a high-fluidity, high-flame-retardancy and high-toughness ABS (Acrylonitrile-Butadiene-Styrene). The high-fluidity, high-flame-retardancy and high-toughness ABS is prepared from the following raw materials: ABS, high glue powder, AS (Acrylonitrile-Styrene) powder, a complex flame-retardant composition, a coupling agent, an antioxidant, an anti-dripping agent and a processing aid. The preparation method of the high-fluidity, high-flame-retardancy and high-toughness ABS comprises the following steps: 1) pretreating, namely sufficiently stirring and mixing AS powder, the complex flame retardant composition, the coupling agent, the antioxidant, the anti-dripping agent and the processing aids at 100-130 DEG C; 2) placing the pretreated mixture obtained in the step 1), the ABS and the high glue powder in a mixer and mixing fully; 3) placing the thoroughly mixed materials in an extruder, and performing melt extrusion and pelleting. The product disclosed by the invention can achieve the following properties: the Izod notched impact strength is 280J / m, the flame retardancy of the sample of which the thickness is 0.8mm achieves the UL94V0 level, and the flame retardancy of the sample of which the thickness is 1.6mm reaches the UL945VA level.

Description

technical field [0001] The invention relates to an ABS with high fluidity, high flame retardancy and high toughness and a preparation method thereof. Background technique [0002] The current electronic products tend to be thin-walled, and the thickness of many products is below 1mm. Due to the safety requirements of electronic products, the products need to meet the UL-94V-0 flame retardant requirements, and with the thinning of electronic products, the toughness of materials And liquidity also put forward more stringent requirements. [0003] In the prior art, there is no good, comprehensive and balanced solution to the flame retardancy, toughness, and fluidity of ABS materials used in thin-walled electronic products. It is necessary to develop an ABS material with high fluidity, high flame retardancy, and high toughness. Contents of the invention [0004] The object of the present invention is to provide a kind of ABS with high fluidity, high flame retardancy and high ...
