The
processing method comprises the following steps: conveying
kraft paper into an impregnation frame which is fully impregnated with phenolic resin, carrying out
vibration treatment, enabling the
kraft paper to upwards float out of the liquid level, injecting a mixed glue solution of the phenolic resin and a
light curing agent into the upper surface of the
kraft paper through an injection mechanism, and carrying out curing treatment on the upper surface of the kraft paper; meanwhile, high-pressure air injection is conducted on the upper surface of the kraft paper through an air injection mechanism, the kraft paper obtained after
permeation continues to be conveyed to the
drying oven to be dried, and then the kraft paper is collected in a winding mode; and finally,
cutting the dried kraft paper, and pressing at high temperature to form the fireproof plate. When kraft paper is subjected to gum dipping, high-frequency vibration is started, the activity of fireproof gum is promoted, meanwhile,
permeation treatment is carried out after gum dipping is completed, gum liquid is further injected,
compressed air injection is matched, gum dipping
permeation is improved, the adherence between subsequent laminated paper
layers is guaranteed, and the fireproof performance is improved.
