Description

Technical Field

[0001] The utility model relates to the technical field of resin storage devices, in particular to a storage device for processing solvent-free polyurethane resin. Background Art

[0002] Solvent-free polyurethane resin is a polyurethane resin that does not contain solvents. Solvent polyurethane resin does not require the use of organic solvents during production and use, reducing the volatilization of organic solvents and the pollution to the environment. Solvent polyurethane resin has good yellowing resistance. It can maintain good transparency and appearance stability in long-term use and is not easy to yellow. When storing solvent-free polyurethane resin, it usually requires a special resin storage device for storage.

[0003] When solvent-free polyurethane resin is stored for a long time, the resin components are easily separated or deposited. The existing storage device is not convenient for stirring the solvent-free polyurethane resin and cannot maintain the uniformity of the solvent-free polyurethane resin. In addition, most of the existing storage devices are directly fixed on the ground through a support frame. When a storage device filled with a large amount of resin needs to be transported, it usually requires multiple workers to carry it together, which is laborious and troublesome. In order to solve the above problems, the present application proposes a storage device for processing solvent-free polyurethane resin. Utility Model Content
