Preparation method for special adhesive composite resin

The invention provides a preparation method for special adhesive composite resin. The method comprises the following steps: (1) taking 1,000 parts of a terpene-rich fraction, 500 parts of a C5 fraction, and 1 part of liquid aluminum trichloride, after a reaction under stirring is completed, adding 2 parts of ethanol, performing stirring at a constant temperature, allowing the stirred material tostand for layering, taking a liquid at the lower layer, and performing distillation under reduced pressure to obtain adhesive resin; (2) taking 600 parts of the adhesive resin obtained in the step (1), mixing the taken adhesive resin, 150 parts of styrene-indene resin, 150 parts of alkyne resin and 100 parts of 1102 resin, and performing a reaction at a temperature of 200-260 DEG C to obtain mixedadhesive resin; and (3) taking 800 parts of the adhesive resin obtained in the step (2), reacting the taken 800 parts of the adhesive resin with 200 parts of white carbon black at a temperature of 260-280 DEG C to obtain the s
