Abstract

The invention belongs to the technical field of polycarbonate processing, and specifically relates to a polycarbonate additive mixing and adding system, comprising a mixing preparation tank, a filter, a feeding tank, a pumping pump and a static mixer sequentially connected through a delivery pipe; The terminator of polycarbonate is housed in the mixing and preparing tank, the inner wall of the mixing and preparing tank is wound with a heat conduction pipe, and the top of the mixing and preparing tank is provided with a feeding hopper for auxiliary agents to be put in, and the static mixer is provided with a There is an oligomeric polycarbonate feed inlet, and the pump is connected to the oligomeric polycarbonate feed inlet. The invention enables the auxiliary agent to be dissolved in the terminator required in the production process of polycarbonate, avoiding the introduction of a new auxiliary agent solvent, so that the auxiliary agent can better improve the quality and performance of polycarbonate products.

Description

technical field [0001] The invention belongs to the technical field of polycarbonate processing, and in particular relates to a polycarbonate additive mixing and adding system and a use method thereof. Background technique [0002] Polycarbonate is a high molecular polymer containing carbonate groups, which has high impact strength, high dimensional stability, wide range of service temperature, good electrical insulation performance, heat resistance and non-toxicity. Widely used in medical equipment, building materials, electronic appliances and other industries. [0003] In order to improve the performance of polycarbonate, some additives such as antioxidants, anti-ultraviolet agents, and mold release agents are usually added in the production process. These additives generally have a higher melting point. Currently, in order to speed up the melting of additives, Often new solvents need to be introduced. [0004] However, if a new solvent is introduced, the new solvent is...
