Abstract

The invention is applicable to the technical field of rosin processing, and provides a preparation method and processing equipment of rosin resin, in the preparation method of the rosin resin, nano aluminum oxide is modified to serve as a carrier, so that the nano aluminum oxide has good carrying capacity and is beneficial to carrying silicon dioxide; silicon dioxide is used as a carrier, so that the reaction can be well catalyzed, impurities in the rosin resin can be adsorbed, and the color of the rosin resin can be lightened; an antioxidant is added in the preparation process of the rosin resin, so that the rosin resin can be effectively prevented from being oxidized, the color of the rosin resin is further lightened, and meanwhile, the thermal stability of the rosin resin can be effectively improved; and the rosin resin processing equipment disclosed by the invention has a good heat preservation and heat insulation effect, and is beneficial to the proceeding of a reaction.

Description

technical field [0001] The invention belongs to the technical field of rosin processing, and in particular relates to a method for preparing rosin resin and processing equipment thereof. Background technique [0002] Rosin, also known as turpentine, is the substance distilled from the resin contained in pine trees. It is solid and transparent in appearance, light yellow or brown in color, hard and brittle, insoluble in water and soluble in alcohol. It can be used in industry, Flux, Chinese medicinal materials, stringed musical instruments, etc. According to its source, rosin is divided into three types: gum rosin, wood rosin and tall oil rosin. Gum rosin is also called relaxing incense, with light color, large acid value and high softening point; wood rosin is also called leaching rosin, its quality is not as good as gum rosin, dark in color, small in acid value, and easy to crystallize from certain solvents; tall oil rosin Also known as tall oil rosin. Rosin is a transpa...
