Aether of glycerine of much phenol shrink epoxy resin is a kind of many luscious round epoxy resin. The annulus oxygen that there are two aboves in its element base, because the cross-linking density of condensate is big, have admirable hear resistance, intensity, model quantity, insulating property, be able to bear or endure ability in swimming and corrosion resistance. Have variety commonly usedly.
One, epoxy resin of line phenol formaldehyde (EPN) , it is by small element thermoplastic chloric propane of colophony of line phenolic aldehyde and annulus oxygen issues condensation polymerization in alkaline action and become. Hold the advantage of phenolic aldehyde colophony and double phenolic A epoxy resin concurrently. Reach colophony of the line with phenolic hydroxyl diverse content phenolic aldehyde with opposite element quality, can synthesize colophony of the line with a quality of different and opposite element and phenolic hydroxyl diverse content phenolic aldehyde, with likeness of double phenolic A epoxy resin, can use one footwork or 2 footwork synthesis. Use 2 footwork to be able to acquire the phenolic aldehyde epoxy resin with relatively inferior viscosity, style of its element structure is:
The technical standard of homebred epoxy resin sees watch 1-18.
Phenolic aldehyde epoxy resin is tall viscosity semisolid normally below room temperature, n of average degree of polymerization is 1~3 about, when N=0, namely epoxy resin of double phenolic F, so oxygen of annulus of phenolic aldehyde epoxy resin base reactivity and epoxy resin of double phenolic F are very similar. Can wait for solidify agent solidify with Zun of amine, acid anhydride, Mi. The function of condensate is the phenolic aldehyde epoxy resin of 4 with functionality best.
