Description

Technical Field

[0001] The utility model relates to the technical field of unsaturated polyester resin modifiers, and specifically relates to a reaction kettle for unsaturated polyester resin modifiers. Background Technique

[0002] Unsaturated polyester resin (UPR) is a widely used polymer material, which has excellent mechanical properties, chemical corrosion resistance and easy processing. In order to further improve or adjust the performance of UPR, modifiers are often used. Modifiers are a class of compounds that can be compatible with the UPR system and can significantly change its physical and chemical properties. When selecting a suitable modifier, factors such as the application field, performance requirements and cost of UPR need to be considered. By reasonably adding modifiers, the performance of unsaturated polyester resin can be optimized and customized to meet the needs of specific usage environments.

[0003] In the preparation process of unsaturated polyester resin, it is necessary to carry out a mixing reaction with modifiers, so a reaction kettle is required. Although traditional reaction kettles have the ability to mix, they still have some deficiencies. For example, their sealing performance is not ideal, so it is easy to cause leakage, which will have a certain impact on the internal reaction. And when discharging, it is easy to cause blockage due to the viscous state of unsaturated polyester resin, thus affecting its normal discharging. Therefore, a reaction kettle for unsaturated polyester resin modifiers is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the utility model is to provide a reaction kettle for unsaturated polyester resin modifiers, whose sealing performance is relatively ideal, so it is not easy to cause leakage, thus avoiding affecting the internal reaction. And when discharging, it is not easy to cause blockage due to the viscous state of unsaturated polyester resin, thus ensuring its normal discharging, so as to solve the problems raised in the above background technique.
