Abstract

The invention provides flame-retardant ABS (acrylonitrile butadiene styrene) composite and a preparation method thereof. The flame-retardant ABS composite comprises components in parts by weight as follows: 70-90 parts of ABS, 16-24 parts of LDH-SEP (lactate dehydrogenase-lactate dehydrogenase), 8-12 parts of APP (atactic polypropylene), 10-16 parts of PER (pentaerythritol ester rosin) and 0.1-0.5 parts of an antioxidant. LDH-SEP and an expansive flame-retardant system in the flame-retardant ABS composite have very good flame-retardant synergistic effect, catalytic charring of the system is facilitated, the flame retardant rating of the ABS composite is effectively improved, and the quantity of generated toxic gases is reduced; besides, sepiolite adopts a stumpy microstructure and has high surface energy, fiber bundles are easy to form, and pores can be formed among the fiber bundles, so that ABS melts can squeeze into the pores among the fiber bundles, a local embedded structure can be formed, and the mechanical property of the composite is improved.

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 is widely used in the field of material processing, but ABS is flammable and generates a large amount of heat, producing a large number of molten droplets. The flame spreads quickly and is not easy to extinguish . Therefore, when used in fields that have certain requirements for fire performance, ABS must be treated with flame retardant. [0003] At present, ABS flame retardant treatment can be divided into mixed high-efficiency flame retardant resin treatment, structural flame retardant treatment, adding inorganic filler treatment, etc. Adding flame retardants or flame retardant materials is currently the main flame retardant method for ABS. Existing flame-retardant ABS materials have complex c...
