Description

Technical Field

[0001] The utility model relates to the technical field related to the production of waterborne polyurethane, in particular to a conveying and feeding device for the production of waterborne polyurethane. Background Technique

[0002] Waterborne polyurethane is a new polyurethane system that uses water instead of organic solvents as the dispersion medium. Water is used as the solvent, which has the advantages of no pollution, safety and reliability, excellent mechanical properties, good compatibility, and easy modification. According to the charge properties of hydrophilic groups, waterborne polyurethane can be divided into two major categories: anionic waterborne polyurethane including carboxylic acid type and sulfonic acid type, cationic waterborne polyurethane, and nonionic waterborne polyurethane. Before the prepolymer is dispersed in water, oligomer diols, chain extenders, waterborne monomers, diisocyanates and other ingredients need to be dissolved and dispersed in the corresponding solvents for step-by-step polymerization, and quantitative batching is required. At this time, a conveying and feeding device is needed.

[0003] At present, during the process of conveying and feeding waterborne polyurethane, the angle of the conveying cylinder cannot be adjusted and supported, so that the top of the conveying cylinder cannot reach a suitable height, resulting in a reduction in the efficiency of conveying and feeding, and the practical performance of the conveying and feeding device is relatively low. In addition, waterborne polyurethane cannot be mixed and stirred during the conveying and feeding process. For this reason, the utility model provides a conveying and feeding device for the production of waterborne polyurethane. Summary of the Utility Model
