Embodiment Construction

[0025] The synthesis of Sb-Mo / Br-RGO mainly consists of three steps, such as figure 1 Shown:

[0026] The first step is the bromination of graphene oxide.

[0027] Graphene oxide (GO) was prepared by the modified Hummers method, and dried under vacuum at room temperature for more than one week in a phosphorus pentoxide atmosphere. Weigh 250mg of graphene oxide, put it into a 100mL dry flask with a magnetic stirring bar, add 15g of carbon tetrabromide and 3g of triphenylphosphine, after the addition is complete, raise the temperature to 150°C, and stir for 5 hours at the same time, and wait for the reaction mixture to cool to After room temperature, 30 ml of ethanol was added to the solution. The reaction mixture was filtered, washed with methanol three times, and then dried in vacuum to obtain brominated graphene (Br-GO).

[0028] The second step is to load antimony molybdate on Br-GO.

[0029] Add 1.0g of Br-GO into 100mL of deionized water, ultrasonically disperse at roo...

Abstract

The invention discloses a molybdenum-antimony brominated graphene oxide modified ABS composite flame-retardant material and a preparation method thereof. The ABS nano-composite flame-retardant material is prepared by melt-blending Sb-Mo / Br-RGO and ABS. Sb- Mo / Br‐RGO is uniformly dispersed in the ABS matrix, and the graphene nanosheets are connected to each other to form a barrier layer, which can significantly improve the flame retardancy of ABS and improve the tensile strength of the material, especially when Sb‐Mo / Br‐RGO is added When the content reaches 5.0wt%, dense carbon residue can be produced. When the material encounters flame or heat flow, it can effectively inhibit heat transfer and isolate oxygen, thereby delaying heat transfer and pyrolysis volatiles, greatly improving flame retardancy, and The tensile strength can reach 68.4MPa.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant material preparation, and relates to an ABS flame-retardant material and a preparation method thereof, in particular to a molybdenum-antimony brominated graphene oxide modified ABS composite flame-retardant material and a preparation method thereof. Background technique [0002] ABS resin is an integral part of life today. It also has various properties of polystyrene (PS), styrene-acrylonitrile copolymer (SAN), butadiene-styrene copolymer (BS), so it has excellent comprehensive performance. It is a thermoplastic polymer material with excellent impact strength, strong toughness, wear resistance, easy molding and machining, and is widely used in packaging, furniture, automobiles, electronic appliances and building materials. But ABS is easy to burn and releases black smoke and toxic gases. This has brought serious property losses to people's production and life, and also destroyed the env...
