Preparation device and preparation method for dimer fatty acid modified polyester resin

Abstract

The invention discloses a preparation device and a preparation method for dimer fatty acid modified polyester resin, relates to the technical field of dimer fatty acid modified polyester resin, and aims to solve the problems that an existing dimer fatty acid modified polyester resin preparation device is low in material mixing efficiency during production, uneven mixing is prone to occurring, and the production cost is low. The special performance of the produced product is not stable, and the quality of the product is influenced. A material mixing supporting bracket is installed on one side of the upper end of the hot melting box, a material mixing box is installed at the upper end of the material mixing supporting bracket, a rotary driving bracket is installed in the material mixing box, a stirring anti-sticking bracket is installed outside the rotary driving bracket, and the stirring anti-sticking bracket is connected with the rotary driving bracket in a welded mode; a wear-resistant pad is installed in the stirring anti-sticking support, and an impact bulk material barrel is installed outside the rotary driving support and fixedly connected with the rotary driving support.

Description

technical field [0001] The invention relates to the technical field of dimer fatty acid modified polyester resin, in particular to a preparation device for dimer fatty acid modified polyester resin and a preparation method thereof. Background technique [0002] Resin usually refers to a softening or melting range after being heated. When softening, it has a tendency to flow under external force. It is solid, semi-solid, and sometimes liquid organic polymer at room temperature. The relative molecular weight of the resin is uncertain but usually higher. It has a softening or melting temperature range, has a tendency to flow under external force, and is often shell-shaped when broken. Broadly refers to polymers or prepolymers used as plastic substrates. Generally insoluble in water, soluble in organic solvents. According to the source, it can be divided into natural resin and synthetic resin; according to the different characteristics of its processing behavior, it can be div...
