Abstract

The invention discloses a preparation method of ultra-light-color high-stability hydrogenated terpene-phenolic resin, which comprises the following steps: S1, pulverizing terpene-phenolic resin to obtain pulverized terpene-phenolic resin; s2, a solvent, a catalyst, a catalyst carrier and a stabilizer are added into the crushed terpene-phenol resin, then hydrogen is introduced, the hydrogen pressure is 10-30 MPa, the temperature is increased to 210-240 DEG C, a reaction is conducted for 2.5-8 h, and a post-reaction melt is prepared; s3, releasing the pressure, cooling, discharging, and filtering to remove the catalyst, the catalyst carrier and the stabilizer; and S4, distilling the filtered product to remove the solvent, thereby obtaining the ultra-light-color high-stability hydrogenated terpene-phenol resin. The terpene-phenolic resin prepared by the method is light in color and luster, good in stability and weather resistance, simple in preparation step and green, environment-friendly and pollution-free in preparation process.

Description

technical field [0001] The invention belongs to the technical field of preparation of hydrogenated terpene phenol resin, in particular to an ultra-light-colored and high-stability hydrogenated terpene phenol resin and a preparation method thereof. Background technique [0002] Terpene resins are a series of linear polymers obtained by the catalytic reaction of monoterpenes such as -pinene, -pinene, dipentene, etc. through catalysts. Depending on the molecular weight, it can be liquid or solid. Terpene resins exhibit excellent compatibility, acid and alkali resistance, aging resistance, as well as good thermal stability and electrical insulation, so they are widely used as adhesives and tackifiers in coatings, rubber, plastics and other fields. agent. On the other hand, because of its non-toxicity, it is also widely used in the food industry. Although in the middle of the 20th century, with the development of the petroleum industry and the advancement of petroleum resin sy...
