What are the advantages of silicone resin application, and what are the characteristics? Silicone resin is a highly crosslinked network of polyorganosiloxanes, usually methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, diphenyldichlorosilane or
Various mixtures of methylphenyldichlorosilane are hydrolyzed at a lower temperature in the presence of an organic solvent such as toluene to obtain an acidic hydrolyzate. The initial product of hydrolysis is a mixture of cyclic, linear and crosslinked polymers.
It also usually contains a considerable amount of hydroxyl groups. The hydrolyzate is washed with water to remove acid, and the neutral condensate is thermally oxidized in the air or further polycondensed in the presence of a catalyst to form a highly crosslinked stereo network structure.
Silicone resin paint
In view of the above characteristics, silicone resin is mainly used as an insulating varnish (including varnish, enamel, lacquer, impregnating varnish, etc.) impregnated with H-class motor and transformer coil, and used to impregnate glass cloth, glass cloth and asbestos cloth to make motor sleeve. Pipes, electrical insulation windings, etc. Bonding mica with silicone insulating varnish can produce a large area of mica sheet insulation material, which is used as the main insulation of high voltage motors. In addition, silicone can also be used as a heat-resistant, weather-resistant anti-corrosion coating, metal protective coating, construction waterproof and moisture-proof coating, mold release agent, adhesive and secondary processing into silicone plastic for electronic, electrical and defense industries. In addition, it is used as an insulating material for semiconductor packaging materials and electronic and electrical components.
There are three ways to cure the cross-linking of silicone resin: one is to use a hydroxyl group on a silicon atom to carry out shrinkage polymerization and cross-linking to form a network structure, which is the main way to cure silicone, and the other is to use ethylene attached to the silicon atom. Base, using organic peroxide as a catalyst, similar to the way of vulcanization of silicone rubber: Third, the use of vinyl and silicon hydrogen bonds on the silicon atom for the addition reaction, such as solvent-free silicone resin and foaming agent can be made A foamed silicone resin is obtained. Therefore, silicone resins can be roughly classified into silicone insulating varnishes, silicone coatings, silicone plastics, and silicone adhesives according to their main uses and cross-linking methods.
