Cold-resisting halogen-free inflaming retarding ABS (Acrylonitrile Butadiene Styrene) and preparation method thereof

Abstract

The invention discloses a cold-resisting halogen-free inflaming retarding ABS (Acrylonitrile Butadiene Styrene) material. The cold-resisting halogen-free inflaming retarding ABS material is composed of the following raw materials in parts by mass: 65-85 parts of ABS, 15-25 parts of a halogen-free flame retardant, 0-10 parts of a cold-resisting toughening agent, 0.5-2 parts of a lubricant and 0.5-2 parts of other auxiliary agents, wherein the halogen-free flame retardant is a complex of melamine salt, hypophosphite and a flame retardant synergist; the melamine salt is at least one of melamine cyanurate, melamine phosphate, melamine polyphosphate and melamine pyrophosphate. A preparation method of the cold-resisting halogen-free inflaming retarding ABS material comprises the following steps: (1) uniformly mixing all the raw materials; and (2) fusing and extruding the uniformly-mixed raw materials, cooling by water and dicing to obtain the product. The ABS material prepared by the invention has high impact strength and low-temperature impact strength, has excellent inflaming retarding performance and is free of halogen.

Description

technical field [0001] The invention relates to a cold-resistant halogen-free flame-retardant ABS and a preparation method thereof. Background technique [0002] ABS is the abbreviation of acrylonitrile-butadiene-styrene terpolymer. Due to its excellent physical properties, the market demand is huge. With the continuous improvement of people's living standards and the increasing emphasis on safety, flame-retardant ABS came into being and is widely used in various fields. [0003] Flame-retardant ABS usually adopts the method of adding halogen compounds to achieve flame retardancy. Halogen-based flame retardants have a good balance of cost and performance and a wide range of applications. However, due to environmental protection considerations, the use of halogen-containing flame-retardant materials is increasing globally. Cautiously, the introduction of various regulations has made the trend of halogen-free materials. [0004] However, the usual halogen-free flame-retardan...
