Abstract

The present invention is applicable to the technical field of rosin processing. The present invention provides a preparation method of rosin resin and its processing equipment. In the preparation method of rosin resin in the present invention, nano alumina is modified as a carrier, so that the nano Alumina has a good carrying capacity, which is conducive to carrying silica. By using silica as a carrier, the catalytic reaction can be carried out well, and at the same time, it can absorb impurities in rosin resin, which is beneficial to lighten the color of rosin resin; In the preparation process of the rosin resin in the invention, by adding an antioxidant, the rosin resin can be effectively prevented from being oxidized, the color of the rosin resin can be further lightened, and the thermal stability of the rosin resin in the present invention can be effectively improved at the same time; the present invention The processing equipment of rosin resin has good thermal insulation effect, which is beneficial to the reaction.

Description

technical field [0001] The invention belongs to the technical field of rosin processing, and in particular relates to a preparation method of rosin resin and processing equipment thereof. Background technique [0002] Rosin, also known as rosin, is a substance obtained by distillation of 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 industrial, Flux, Chinese medicinal materials, stringed musical instruments, etc. Rosin is divided into three types: gum rosin, wood rosin and tall oil rosin according to its source. Gum rosin is also called relaxing fragrance, with light color, high acid value and high softening point; wood rosin, also known as leaching rosin, is not as good as gum rosin, dark in color, low in acid value, and easy to crystallize from certain solvents; tall oil rosin Also known as tall oil rosin. Rosin is a transparent,...
