Description
Technical Field
The invention relates to a high-performance flame-retardant epoxy resin-based composite material and a preparation method thereof, belonging to the technical field of composite materials.
Background
Epoxy resin is widely applied to various fields due to the advantages of excellent performance, low cost and the like. Epoxy resins have become indispensable important materials in national economic development, and the yield and application level thereof can reflect the degree of development of industrial technology in one country from one side. In recent years, the development of new technology industry has made higher requirements on the performance and application of epoxy resin. The rail trains and the airplanes occupy a great position in the transportation industry, the demand on the rail trains and the airplanes worldwide is increased year by year, and meanwhile, higher requirements on the carrying capacity, the comfort performance, the environmental protection performance and the safety performance of the rail trains and the airplanes are provided. The epoxy composite material has the characteristics of light weight and high strength, and the composite material can reduce weight, and has better damping performance and the effects of shock absorption and noise reduction.
Trains and airplanes are used as important transportation tools, and high requirements are put on the flame retardant property of materials. Since the oxygen index of a common epoxy resin is only about 19.8, the flammability and the sustained spontaneous combustion after leaving a fire of the epoxy resin are liable to cause a fire, and it is therefore necessary to subject the epoxy resin to a flame retardant treatment.
The existing common technical approach for preparing the epoxy resin with flame retardant property is mainly to modify the epoxy resin by adding a flame retardant into an epoxy resin system, and the two types are common, one type is a halogen-containing flame retardant, and the other type is a halogen-free flame retardant. The halogen-containing flame retardant has high flame retardant efficiency, but is not friendly to products and environment, so the halogen-free flame retardant is used mostly at present. Compared with halogen-containing flame retardants, the halogen-free flame retardants have relatively low flame retardant efficiency, and in order to achieve a certain flame retardant performance, the amount of the flame retardant needs to be increased, which can cause the viscosity of an epoxy resin system to increase and reduce the technological performance of the resin, and on the other hand, the halogen-free flame retardants have excessive use and can adversely affect the gel curing of the composite material.
