Description
Technical Field
The invention belongs to the field of nano composite materials, and particularly relates to a preparation method of a boehmite/graphene composite material.
Background
The halogen-containing flame retardant is a flame retardant product which is most applied to the flame retardance of plastics and rubber at present, and mainly has the advantages of inert chemical property, good compatibility with plastics or rubber products, good flame retardant effect and low use cost. However, in the event of a fire, the halogen-containing flame retardant material generates a large amount of smoke and toxic corrosive hydrogen halide gas, causing secondary damage. Therefore, halogen-free flame retardants have gained wide attention in recent years. At present, the common halogen-free flame retardant mainly comprises aluminum hydroxide, boehmite, magnesium hydroxide, phosphorus flame retardant, intumescent flame retardant and the like. However, aluminum hydroxide, magnesium hydroxide and boehmite need to be added in a relatively large amount to exert flame retardant effect, which often affects the properties of the matrix, especially the mechanical properties of the material; the phosphorus flame retardant has poor heat resistance, high volatility and poor compatibility with a matrix, and has a dripping phenomenon in the combustion process; the intumescent flame retardant has the defects of poor compactness of a generated carbon layer, poor thermal stability and the like.
The graphene is a novel carbon simple substance with a hexagonal honeycomb structure and composed of carbon atoms, and has ultrahigh electrical conductivity and thermal conductivity, an ultrahigh specific surface area, transparency similar to transparency and excellent gas barrier property. However, graphene alone is too expensive as a flame retardant from the economical point of view, and is not suitable for large-scale application. The graphene-based composite material flame retardant compounded by the traditional inorganic flame retardant and the graphene is a novel flame retardant. The flame retardant property of the composite material is superior to that of a single component under the synergistic effect of the inorganic flame retardant and the graphene. According to the invention, a microwave synthesis technology is adopted to prepare the boehmite/graphene composite material as a novel flame retardant.
The microwave synthesis technology is that polar molecules in a microwave field rapidly absorb electromagnetic waves to generate billions of dipole vibration and collision to heat the reaction, and polar substance molecules in the microwave field vibrate and collide to generate heat energy and accelerate the thermal motion among the molecules, so that the transmission speed of the substance is obviously improved. Therefore, the microwave synthesis technology can realize rapid, efficient and uniform heat generation and simultaneously realize efficient mass transfer, greatly improve the heat and mass transfer efficiency of micro mixing, greatly shorten the mixing homogenization characteristic time, meet the uniform environment required by particle nucleation, and improve the conditions of uneven particle size distribution and poorer repeatability of products to a certain extent. Meanwhile, the reaction process shows excellent selective polarity due to different polarities of different substances, so that the reaction efficiency is obviously improved, the quality of a reaction product is improved, and the heat energy utilization rate is improved.
