Description
Technical Field
The invention relates to the technical field of flame retardant materials, in particular to a phosphorus imide-containing alicyclic epoxy molecule and a preparation method thereof.
Background
Epoxy resin is a thermosetting polymer material which is generally characterized by containing two or more epoxy groups, taking aliphatic, alicyclic or aromatic organic compounds as a framework, and forming a three-dimensional cross-linked network through epoxy group reaction, and has been widely applied to the fields of electronic information, aerospace, wind power generation, transportation, deep sea diving and the like because of excellent physical, chemical properties, wettability, adhesiveness, oil resistance, water resistance, corrosion resistance and insulation. Compared with the glycidyl ether type epoxy resin, the alicyclic epoxy resin is obtained by the epoxidation reaction of unsaturated alicyclic compounds through organic peroxy acid, so that the content of free chlorine or metal ions is low, and the condensate has lower dielectric constant and dielectric loss. In addition, alicyclic epoxy resin does not contain strong ultraviolet chromophores such as aromatic rings, and the like, and is decomposed to generate small molecular volatile matters such as carbon dioxide, carbon monoxide, water and the like when being exposed to a high-voltage arc, and free carbon is not generated to form a conductive path, so that the alicyclic epoxy resin has excellent high-voltage leakage resistance. However, the limiting oxygen index of the alicyclic epoxy resin is only about 20%, the alicyclic epoxy resin is extremely easy to burn, and the requirements of the fields of electronics, transportation and the like on fire safety materials cannot be met.
The preparation of the flame-retardant epoxy resin mainly adopts two modes of an additive type and a reaction type, wherein the additive type flame retardance is rapid and simple, but the flame retardant is introduced by adopting a physical blending mode, so that the problems of poor compatibility, easy precipitation, mechanical property deterioration and the like are easy to occur, and the use and development of the flame-retardant epoxy resin are limited; the reactive flame retardation can reduce the risk of deterioration of physical properties of the material, so that the curing system can obtain excellent flame retardation and thermal stability, and can also maintain the performance advantage of the material. In the research of the prior reactive flame-retardant alicyclic epoxy resin, the problem of poor flame retardant performance exists, and the requirement of high fire safety cannot be met.
Therefore, in order to solve the above problems, it is needed to study a flame-retardant epoxy resin, and to greatly improve the flame-retardant performance of the cured epoxy resin, and simultaneously, to meet the requirements of low dielectric properties in the fields of high frequency, high speed and communication through molecular structure design.
Disclosure of Invention
In order to solve the technical problems, the invention discloses a phosphorus-containing imide type alicyclic epoxy molecule and a preparation method thereof, wherein a phosphorus-containing group and an imide structure are simultaneously introduced on the basis of the alicyclic epoxy molecule, and the molecule has the phosphorus-containing group, the imide structure and the epoxy group, so that a condensate of the phosphorus-containing imide type alicyclic epoxy molecule has excellent flame retardant property and dielectric property, and meets the performance requirements of the electronic packaging material in the fields of high-frequency and high-speed communication.
