Abstract

The invention discloses a graphene composite flame-retardant material and a preparation method thereof. The graphene composite flame-retardant material comprises the following raw materials in parts by weight: 30-50 parts of modified graphene and 10-15 parts of a flame-retardant additive, under the action of 1-hydroxyl benzotriazole, amino of the flame-retardant additive and carboxyl of the modified graphene carry out condensation, so that flame-retardant additive molecules are fixed on the surface of the modified graphene, thereby obtaining the graphene composite flame-retardant material. According to the graphene flame-retardant material, oxygen-containing acid of phosphorus catalyzes a hydroxyl-containing compound to be dehydrated into carbon, then a coke layer is generated on the surface of the material, the coke layer can isolate oxygen and heat to extinguish flame, meanwhile, little smoke is generated when the material is combusted, and the flame-retardant performance of the material cannot be reduced due to long-time use.

Description

technical field

[0001] The invention relates to the technical field of flame retardant material preparation, in particular to a graphene composite flame retardant material and a preparation method thereof. Background technique

[0002] Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It is a planar film composed of carbon atoms in a hexagonal honeycomb lattice with sp2 hybrid orbitals. It is a two-dimensional film with a thickness of only one carbon atom. As a material, graphene has unique characteristics and excellent properties, such as quantum Hall effect, high modulus, strength and electron migration rate, huge specific surface area, excellent thermal and electrical conductivity, etc. These characteristics and properties make graphene have very broad application prospects in the fields of energy, electronics, catalysis, biomedicine, and composite materials. Due to its good flame retardancy, graphene is widely used in the preparatio...
