Abstract

The invention provides a flame-retardant ABS composite material and a preparation method thereof, wherein the former comprises the following components in parts by weight: 70-90 parts of ABS; 16-24 parts of LDH-SEP; 8-12 parts of APP; 10-90 parts of PER 16 parts; 0.1-0.5 parts of antioxidant. The LDH-SEP in the flame-retardant ABS composite material provided by the present invention has a good flame-retardant synergistic effect with the intumescent flame-retardant system, contributes to the catalytic charcoal formation of the system, and effectively improves the flame-retardant grade of the ABS composite material. The generation of toxic gas is reduced, and because the microstructure of sepiolite is short columnar, with high surface energy, it is easy to form fiber bundles, and pores can be formed between fiber bundles, so that ABS melt can squeeze into the fiber bundle pores , forming a local embedded structure, thereby improving the mechanical properties of the composite.

Description

Technical field [0001] The invention relates to the field of flame-retardant materials, in particular to a flame-retardant ABS composite material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene (ABS) has good processing properties and has a wide range of applications in the field of material processing, but ABS is easy to burn, and generates a large amount of heat, produces a large number of droplets, and the flame spreads quickly and is difficult to extinguish . Therefore, when used in fields that have certain requirements for fire resistance, ABS must be flame-retardant. [0003] At present, ABS flame-retardant treatment can be divided into mixed high-efficiency flame-retardant resin treatment, structural flame-retardant treatment, and inorganic filler treatment. Adding flame retardants or flame-retardant materials is currently the main flame-retardant method for ABS. The existing flame-retardant ABS materials have complex compone...
