The invention discloses a method for producing terpene resin with a high softening point and belongs to the technical field of deep processing of rosin. The terpene resin is prepared from, by weight, 0.05-0.1 part of silicone glycol modified phosphate ester polymers, 20-25 parts of methylbenzene, 0.2-0.3 part of microcrystal microcrystalline cellulose, 20-25 parts of turpentine and 0.1-0.2 part of aluminum chloride anhydrous. The method includes the steps that the silicone glycol modified phosphate ester polymers, methylbenzene, microcrystal microcrystalline cellulose, turpentine and aluminum chloride anhydrous are put into a reaction kettle to be mixed to be uniform, a heat preservation reaction is conducted at the temperature of 0-5 DEG C for 0.5-1 hour, and then distillation is conducted. Based on an existing preparation method of terpene resin, a certain proportion of the silicone glycol modified phosphate ester polymers and microcrystal microcrystalline cellulose are added in the preparation process of t
