Abstract

The invention relates to a flame-retardant ABS (acrylonitrile butadiene styrene) composite material, which is prepared from the following ingredients in parts by weight: 82 parts to 85 parts of ABS, 20 parts to 23 parts of flame retardants, 2 parts to 4 parts of needle-shaped nano calcium carbonate, 0.1 part to 0.5 part of antioxidants, 0.1 part to 0.5 part of lubricating agents and 0.1 part to 0.3 part of light stabilizers. Through the anti-dropping effect of the needle-shaped nano calcium carbonate, the consumption of the flame retardants is reduced; the material is saved; meanwhile, the flame-retardant effect is ensured; the rigidity of the composite material is improved to different degrees; the flowability of the composite materials is ensured.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a flame-retardant ABS composite material and a preparation method thereof. Background technique [0002] Acrylonitrile-styrene-butadiene copolymer (ABS) is one of the five major synthetic resins. It has good processing properties and is widely used in the field of material processing. However, ABS has poor flame retardancy and generates heat when burning. Large, a large number of molten droplets will be produced, the flame spreads quickly and is not easy to extinguish. Therefore, when used in areas with certain requirements for fire resistance, ABS must be modified for flame retardancy. [0003] As far as the current flame retardants are concerned, there are mainly two categories: halogenated flame retardants and halogen-free flame retardants. In actual research and application, in order to achieve the ideal flame retardant effect while reducing the amount of main fla...
