Description
Technical field
The present invention relates to a kind of no-solvent type insullac.
Background technology
Along with the development of progress of science and technology, aerospace and Defence business, electrical equipment and electrical is more and more higher to the requirement of insullac.Improve the insullac temperature classification and can make voltage raising, electric capacity increase, volume-diminished, the weight saving of electrical equipment, and can under severe condition such as high temperature, height carry, move and save the cost of electrical equipment reliably and with long-term.Developed the novel fire resistant insullac of many trades mark both at home and abroad successively, the America and Europe, household electrical appliance have all used F level (155 ℃) and H level (180 ℃) insullac basically, at present, the above insullac kind of external employed F level mainly contains polyethersulfone (ketone), diphenyl ether, silicone resin, modified poly ester and polyamides (Asia) polyimide resin class, though these insullac kind development rapidly, but owing to exist the shortcoming of solvability and poor processability, and in use add a large amount of organic solvent contaminate environment.In order to solve the existing above-mentioned shortcoming of solvent-borne type insullac, people study the solvent-free insulated paint that does not use solvent.At present, solvent-free insulated paint mainly is to be mixed and made into mutually by synthetic resins, reactive thinner and solidifying agent, its action principle is, solvent-free insulated paint at room temperature is liquid, after being immersed in them on electric equipment products, heat then, synthetic resins, thinner just solidify to form insulating material under the effect of solidifying agent.Synthetic resins has kinds such as epoxies, polyester and epoxy polyester, and is wherein more with epoxy resin.Though the relative solvent-borne type insullac of no-solvent type insullac has reduced organic solvent pollution on the environment problem to a great extent, but owing to be subjected to the prescription of solvent-free insulated paint itself and as the restriction of the performance of the resin of insullac main body, existing no-solvent type insullac can not satisfy the more and more needs of the application of high request.
Chinese patent application 200610040434.X discloses a kind of non-solvent epoxy unsaturated polyester resin heat resistance paint, the vinylbenzene of this patent employing 12～35% is made thinner, nearly about 15% vinylbenzene volatilization loss is arranged in the solidification process, operating environment of pollution still can not satisfy low volatilization environmental friendliness insulating material and energy-saving and cost-reducing requirement.
Summary of the invention
