| titleOfInvention | A kind of terpene resin and its production process |
| abstract | The invention provides a terpene resin and a production process thereof. The production process includes the steps of turpentine oil pretreatment, polymerization, first water washing, hydrolysis, second water washing, and negative pressure distillation, and the color of the product is reduced by the turpentine oil pretreatment step. , the color of the obtained terpene resin is lighter; by controlling the mass ratio of aluminum trichloride/boron trifluoride in the polymerization step, the yield of the product is greatly increased without affecting the color of the product; by adding rosin in the second washing The amine toluene solution greatly reduces the chloride ion content in the product and meets the technological requirements of hydrogenated terpene resin. |
