ABS halogen-free environment-friendly flame-resistant material and preparation method

Abstract

The invention relates to an ABS halogen-free environment-friendly flame-resistant material. The ABS halogen-free environment-friendly flame-resistant material consists of the following substances: magnesium hydroxide, melamine cyanurate, zinc borate, diantimony trioxide and ABS, with a ratio of magnesium hydroxide to melamine cyanurate to zinc borate to diantimony trioxide to ABS being (7.5-20):(1-10):(0.5-10):(1-15):(60-90). A method for preparing an ABS halogen-free environment-friendly flame-resistant material is characterized in that the method comprises the following steps: drying ABS in an environment at 80 DEG C, mixing magnesium hydroxide, melamine cyanurate, zinc borate and diantimony trioxide, and then performing grinding through a kneading machine to obtain a composite flame retardant; mixing ABS with the composite flame retardant in a mixing machine, and extruding the mixture through an extruding machine to perform granulation; drying particles prepared through blending at 80 DEG C; performing packaging, weighing, quality inspection and warehousing. The halogen-free requirement of the ABS halogen-free environment-friendly flame-resistant material provided by the invention reaches the requirement in IEC 61249-2-21, and the flame-retardant level can reach level V-1 and even V-0.

Description

technical field [0001] The invention relates to a flame-retardant material and a preparation method thereof, in particular to an ABS halogen-free environment-friendly flame-retardant material and a preparation method thereof. Background technique [0002] Due to the characteristics of the ABS material, if the current ABS material needs to achieve the ideal flame retardant effect, it needs to add a large amount of halogen elements such as fluorine, chlorine, bromine, and iodine. Materials containing halogen elements will release a large amount of toxic gases containing harmful substances during combustion or heating, threatening human health and the environment. [0003] Although there are existing halogen-free ABS flame retardant materials on the market, they all have the characteristics of low flame retardant efficiency and large addition amount, which seriously deteriorates the material performance, and at the same time severely limits the scope and prospect of the materia...
