Firstly, silicon nitride is uniformly dissolved in dichloromethane, then glycidyl amine epoxy resin is added and is evenly stirred, and then heating and drying are performed under the established conditions to obtain a glycidyl amine epoxy resin system containing silicon nitride; then an imide polymer is evenly mixed in the dichloromethane to obtain an imide polymer solution; afterwards, the imide polymer solution is evenly mixed in the glycidyl amine epoxy resin system containing the silicon nitride, and drying and heating are performed to obtain the glycidyl amine epoxy resin system containing the silicon nitride and the nano imide polymer; a solidifying agent and an accelerator are added to the glycidyl amine epoxy resin system, and even stirring and constant-temperature curing are performed to obtain the abrasion-resistant sealing material.
Description
Technical field
The invention belongs to technical field of polymer composite materials, more particularly to a kind of abrasive sealing materials and its preparation side
Method.
Background technology
For many years, silicon nitride has attracted scientific research creator's as the material for having presence nature with its excellent performance more
Note, therewith, the preparation method of silicon nitride is more and more perfect, but for its more extensive multi-functional application, be ability
The mission that field technique person bears always.Research finds that silicon nitride has very strong chemical stability, is formed continuously in three dimensions
And firm network structure.Many performances of silicon nitride are all attributed to this structure.Pure Si3N4 is 3119, has two kinds of α and β brilliant
Body structure, is hexagonal crystal form, and its decomposition temperature is 1800 DEG C in atmosphere, is 1850 DEG C in 011MPa nitrogen.Si3N4 heat is swollen
Swollen coefficient is low, thermal conductivity is high, therefore its resistance to sudden heating is splendid.The silicon nitride of hot pressed sintering is put in cold water after being heated to l000 DEG C
Will not also rupture.At less high temperature, Si3N4 has higher intensity and an impact resistance, but can be with more than 1200 DEG C
The growth of use time and there is breakage so as to intensity decreases, be more easy to fatigue damage occur more than 1450 DEG C, so Si3N4
Use temperature be usually no more than 1300 DEG C.Due to the solid density of Si3N4 it is low, it is lighter than steel and engineering superalloy steel
It is many, so, where those require that material has the properties such as high intensity, low-density, high temperature resistant go to replace closing with Si3N4 ceramics
Jin Gang is to suit somebody to a T.
Its pole high temperature resistant, intensity can maintain 1200 DEG C of high temperature always and not decline, and will not be melt into melt body after being heated,
Until 1900 DEG C can just be decomposed, and there is surprising resistance to chemical corrosion, be resistant to almost all of mineral acid and less than 30%
Soda bath, be also resistant to the corrosion of many organic acid；It is a kind of high-performance electric insulant again simultaneously.Meanwhile, raw material into
This is low, and preparation method process is pollution-free, easy to operate, and the extensive application for silicon nitride provides reliable prospect.
Based on its beneficial wearability and thermal stability property, the present invention intends providing a kind of abrasive sealing materials and its prepares
Method.
The content of the invention
Based on above-mentioned present situation, it is an object of the invention to provide a kind of abrasive sealing materials, and preparation method thereof, can be effective
The wearability for improving glycidyl amine epoxy resin system and heat stability.For achieving the above object, the present invention is adopted
Technical scheme be：A kind of abrasive sealing materials, and preparation method thereof, containing following program：To nitrogenize by set proportioning first
Silicon is dissolved in dichloromethane, is subsequently adding glycidyl amine epoxy resin, is obtained containing the glycidyl amine for having silicon nitride
Based epoxy resin system；Imide polymer is mixed in dichloromethane by proportioning again, obtains imide polymer solution；So
It is mixed in the glycidyl amine epoxy resin system containing silicon nitride afterwards, by determined temperature, time dry heat, is obtained
Glycidyl amine epoxy resin system containing silicon nitride and imide polymer；In above-mentioned glycidyl amine epoxy resin
By proportioning addition alicyclic amines firming agent in system, polyethers amine type accelerator, after stirring, isothermal curing obtains this
A kind of abrasive sealing materials that invention is proposed.
Improvement, development, research for the demand present situation, the invention has benefit that, in order to increase existing skill
The function of the generation of art, there is provided it is a kind of it is workable, provide that design is brief, multiple-effect is shared, convenient and safe one kind for using
Abrasive sealing materials, and preparation method thereof, applied widely, cost is relatively low, simple to operate, and it is a kind of wear-resisting close that the present invention is provided
Closure material, and preparation method thereof, the growing production and construction of diversification and living needs can be met, be science, ecology,
Environmental protection, the multi-effect scheme of sustainable development.
Described above is only the general introduction of technical solution of the present invention, in order to be able to better understand the technological means of the present invention, and
Can be practiced according to the content of description, and be allow the present invention above and other objects, features and advantages can be brighter
It is aobvious understandable, below especially exemplified by preferred embodiment, describe in detail as follows.
Specific embodiment：
