Preparation Method.
Background technology
With the development of China's 500kV power systems, and electric railway and the construction of large-scale iron and steel base, in order to
Ensure the safe operation of power system, need that the reactive power that reactor carrys out compensating electric capacity is installed in large-scale Key Substation
Trend it is more and more obvious.Reactor generally pours iron core and coil and forms by insulant, but insulant for a long time compared with
Under high temperature, electric field and the action of a magnetic field, can gradually lose original mechanical property and insulating properties, for example become fragile, machinery it is strong
Degree weakens, electrical breakdown.And the insulant in reactor will bear the load of reactor operation generation and the effect of surrounding,
The summation of these loads, intensity and determine the service life of insulant action time.
At present, in terms of the insulant for reactor, either phase insulation, or layer insulation, its insulation material
Material is broadly divided into two big class, and a class is insulating cement, and a class is insulating board；Wherein using it is relatively broad be insulating board, by
There are certain insulating properties in fiber sheet, and using more convenient, so be often used to do insulating board using.But due to fibre
Dimension cardboard sheet has elasticity greatly as single layer structure, flexible, not the features such as easy-formation, and easily causes reactor open circuit, shadow
Ring the service life of reactor；Additionally, fiber sheet sheet is as some layers of paper material, unprotect measure, moisture-sensitive, direct shadow
Ring reactor resistance value to stablize, make the reactor proof voltage breakdown value low, thus seek a kind of new insulant into
For urgent problem in the art.

S2, in parts by weight, by 15-20 part nano silicons, 2-4 part complex stabilizer, 5-7 parts fire retardant and 35-40 parts
Epoxy resin mixes, and is placed in CO25-8min is stirred under atmosphere, high speed shear dispersion 30-45min, rotating speed is controlled in 2000-
2500r/min, obtains mixture B；
The mixture B mixing that S3, the mixture A that step S1 is obtained and step S2 are obtained, in vacuum condition heated and stirred, cooling
To room temperature, solidification is obtained final product.
Further, also need to add ZnOw 2-5 parts when step S3 mixes.
Further, heating-up temperature is 35-50 DEG C in step S3.
Further, hardening time is 1-3h in step S3.
Further, complex stabilizer is calcium stearate, castor oil acid calcium, zinc stearate, Oleum Ricini in step S2
At least one in sour zinc and epoxy soybean oil.
Further, fire retardant is the one of which in magnesium hydroxide and aluminium hydroxide in step S2.
Beneficial effects of the present invention are：The present invention adds metallocene polymers in insulant, can reinforced insulation material
Water-fast, moisture resistance properties, that is, improve the electric insulation performance of material；And the vertical structure body of metallocene polymers is more regular, it is easy to
Scattered small size spherocrystal is formed, the degree of crystallinity and toughness of insulant can be improved, so as to improve the use longevity of insulant
Life；The raw material that the present invention is used is easy to get, and rationally, preparation method is simple for component compatibility, and production efficiency is high, and product yield is high, is suitable for
In industrialized production, and product good insulation preformance, fire resistance is strong, substantially increases the safety coefficient of reactor.
