Insulation Materials The Process Is Simple
Epoxy resin, polyester resin, phenolic resin, diphenyl ether resin, Insulation Materials polyimide, melamine formaldehyde resin, silicone resin, fluororesin, other resin.
Phenolic resin has the advantages of good raw material source, Insulation Materials simple process and low cost. It has good mechanical properties, electrical insulation properties and thermal stability. The output of phenolic resin is the first of the thermosetting resin. The most widely used resin in the production of electrical insulating material The
Raw materials: melamine, Insulation Materials formaldehyde melamine, also known as melamine, or melamine, C3N6H6, white crystals, density 1.573g / cm3, slightly soluble in ethanol, insoluble in water, ethylene glycol, glycerol and pyridine, insoluble in ether, Benzene and carbon tetrachloride.
Refers to a resin in which two or more epoxy groups are contained in their molecules and a cured body of a body structure can be obtained in the presence of a suitable reagent.
Epoxy resin advantages: strong adhesion; shrinkage small; high dielectric properties; Insulation Materials good mechanical properties; good heat resistance; good chemical stability. Can be used as insulating paint, insulation laminates, plastic, insulating mica products, in addition to insulation and adhesive can also be used.
1) no accelerator is the characteristics of acid anhydride curing: curing speed affected by the amount of hydroxyl; esterification reaction consumption of anhydride, Insulation Materials etherification reaction does not consume hydroxyl; epoxy groups need less than 1, usually 0.85
2) When there is an accelerator, the tartant forms an ion pair with the anhydride; the epoxy group is inserted into the ion pair, the carboxyl anion opens the epoxy group, forms the ester bond, and produces a new anion; the anion can be formed with the acid anhydride New ion pairs, or the epoxy ring, Insulation Materials the reaction will continue
1, molecular structure: diphenyl ether resin is the main chain of diphenyl oxide (or diphenyl ether) with methylene cross-linked aromatic series of polymers, which is called diphenyl ether resin
2, the advantages: thermal stability, dielectric properties, Insulation Materials mechanical properties, chemical resistance
3, the application: the production of resin factory, insulation materials plant to buy resin or modified reproduction of insulating materials. Insulation Materials Diphenyl ether resin is a quality and cheap H-class material; used as a dipping paint; used as a laminate resin; impregnated glass cloth, glass yarn, asbestos fabric; prepared reinforced plastic; used as mica adhesive
