The invention discloses a method for preparing diphenol type
phosphor-containing high flameproofing
benzene-oxaxine resin, which uses monoamine,
phosphor-containing diphenol
formaldehyde as raw reaction materials. A
benzene-oxaxine midbody is introduced with a compound containing
phosphor to synthesize a phosphor-containing flameproofing
benzene-oxaxine midbody which is solidified and crosslinked to obtain thermalsetting phosphor-containing high flameproofing benzene-oxaxine resin. Other fire retardants are not required to be added into the flameproofing materials which adopt the phosphor-containing flameproofing benzene-oxaxine resin of the invention as the basic flameproofing material; the flameproofing material using the resin has excellent flameproofing capacity, the flameproofing level can reach V-0, the thermal capacity is rather good and the
vitrification transforming temperature can reach 225 DEG C. The phosphor-containing flameproofing benzene-oxaxine midbody which is prepared by the method of the invention can be individually used or used by being mixed with other type benzene-oxaxine midbody or phenolic resin or
epoxy resin; an obtained solidified product has higher
thermal resistance, and the phosphor-containing flameproofing benzene-oxaxine midbody is applicable to the production of
structural material, flameproofing material, electric insulation material, electronic encapsulation material,
ablation resistance material or braking material with high capacities which are used at the temperature higher than 180 DEG C.
