Abstract

The invention relates to an environment-friendly flame-retardant ternary composite material POSS/GO/ZIF-8 and a preparation method thereof. With the rapid development of the China and the increasinglyenhanced environmental protection, safety and health consciousness, the flame retardant property and environmental protection property of existing flame retardant materials cannot meet the requirements of people. According to the invention, graphene oxide (GO), polyhedral oligomeric silsesquioxane (POSS) and a zeolite imidazole framework material (ZIF-8) are compounded so as to prepare the ternary composite material. Compared with a single-component flame retardant and a binary composite flame retardant, the flame retardant property of the ternary composite material is improved, and meanwhile, the environmental protection requirement is met; and ultrasonic waves are used for dispersion in the preparation process of the ternary composite material, so it is guaranteed that dispersion liquidis stable, uniform and free of agglomeration, the process is simple, and feasibility is high.

Description

technical field [0001] The invention relates to the technical field of design and preparation of a flame retardant, in particular to an environmentally friendly flame-retardant ternary composite material POSS / GO / ZIF-8 and a preparation method thereof. Background technique [0002] With the rapid development of the country, the increasing awareness of environmental protection, safety and health, and the instillation of the concept of fire prevention, people have higher and higher requirements for the flame retardant performance and environmental protection performance of flame retardant materials. [0003] Metal organic framework material is a new type of organic-inorganic hybrid material, which can be used as an environmentally friendly flame retardant in epoxy resin, polycarbonate, polyurethane and other flame retardant fields [Xu W, Wang G, Xu J, et al.Modification of diatomite with melamine coated zeolitic imidazolate framework-8as effective flame retardant to enhance fla...
