Ultra-light color high-stability terpene resin and preparation method thereof

The invention discloses an ultra-light color high-stability terpene resin and a preparation method thereof. The method comprises the following steps: S1) crushing terpene resin, thereby acquiring crushed terpene resin; S2) adding a solvent, vegetable oil, a catalyst and a catalyst carrier into the crushed terpene resin, introducing hydrogen under the hydrogen pressure of 5-30MPa, raising temperature to 80-300 DEG C and reacting for 1-10h, thereby acquiring a reacted fused matter; and S3) releasing pressure, distilling and removing the solvent, thereby acquiring the ultra-light color high-stability terpene resin. The terpene resin disclosed by the invention is in light color and luster, is high in heat stability and high in antioxidant activity and can be widely applied to an adhesive, solvent type acrylic ester, EVA/SIS hot melt adhesive, and the like. 本发明公开了种超浅色高稳定性萜烯树脂及其制备方法，包括以下步骤制成：S1：将萜烯树脂粉碎，制得萜烯树脂粉碎物；S2：向萜烯树脂粉碎物中加入溶剂、植物油、催化剂、催化剂载体，接着通入氢气，氢气压力为5-30MPa，升温至80-300℃，反应1-10h，制得反应后熔融物；S3：接着卸压并蒸馏除去溶剂，制得超浅色高稳定性萜
