Description
Technical field
The present invention relates to field of compound material, particularly relate to a kind of insulating composite material.
Background technology
In transformer long-time running, Mierocrystalline cellulose is degraded, and causes insulation paper and insulcrete aging gradually, loses some mechanical performance and electric property.Mierocrystalline cellulose heat-resistant aging is poor, and this is the maximum shortcoming of insulation paper.Oil formula is transformer insulated, and use temperature is 105 DEG C, can accelerate the oil deterioration that insulate, affect its work-ing life when temperature is too high.The transformer of design service life 20-30 105 DEG C time, after temperature raises 6-7 DEG C, work-ing life seriously reduces, and will only have the work-ing life of several years.The shortcoming of domestic insulation Paper or cardboard non-refractory, physical strength, electrical strength difference limits transformer to miniaturization, Large Copacity future development.In recent years, synthetic insulating material superior performance, obtains many application at electrical technology field.Particularly resistance toheat exceeds electrician's cardboard, greatly enhances insulation high-temperature-resistant, ageing-resistant performance.Macromolecule polymer material, through development for many years, power engineering is widely used, and machinery, the electric property of multiple polymers material are all better than insulation paper.Therefore, new polymers solid composite insulating material generally uses in oil-filled transformer.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of insulating composite material is provided, meets the primary demand in market.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of insulating composite material, comprise TM-196 resin, dull and stereotyped gel coat, alkali-free grid glass-fiber-fabric, solidifying agent, promotor, polyvinyl alcohol, ethanol, releasing agent, described solidifying agent adopts methyl ethyl ketone peroxide solution, described promotor adopts cobalt naphthenate solution, the percent mass ratio of described TM-196 resin, methyl ethyl ketone peroxide solution, cobalt naphthenate solution is 94:2:5, the polymerization degree of described polyvinyl alcohol is 1700 and alcoholysis degree is 90%, containing 10% active oxygen in described methyl ethyl ketone peroxide solution, in described cobalt naphthenate solution, cobalt contents is 5% ~ 10%.
Further, described releasing agent preparation method comprises the following steps: dropped in 500 parts of water by described polyvinyl alcohol 50 parts, be heated to superpolymer and all dissolve, add 450 parts of ethanol after liquid cooling but to be cooled again, crosses and filters impurity, can obtain required releasing agent.
Further, described material preparation method comprises the following steps: described TM-196 resin, methyl ethyl ketone peroxide solution, cobalt naphthenate solution are mixed into unsaturated polyester sizing material, evenly die surface is cleared up and air-dry with described releasing agent, another use dull and stereotyped gel coat sizing material is coated with the thick gel coating resin of 10 ~ 20mm at mould inner surface, then alkali-free grid glass-fiber-fabric is spread, coat unsaturated polyester sizing material, the self-vulcanizing demoulding.
Further, described mould adopts original-pack PP plastic components to make.
The invention has the beneficial effects as follows:
