Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane adhesives, in particular to a polyurethane adhesive containing device. Background Art

[0002] Polyurethane adhesive refers to adhesives containing carbamate groups or isocyanate groups in the molecular chain. Polyurethane adhesives are divided into two categories: polyisocyanates and polyurethanes. Polyisocyanate molecular chains contain isocyanate and carbamate groups, so polyurethane adhesives show high activity and polarity. They have excellent chemical adhesion to substrates containing active hydrogen, such as porous materials such as foam, plastic, wood, leather, fabric, paper, ceramics, and materials with smooth surfaces such as metal, glass, rubber, and plastic. The storage of polyurethane adhesives is very important. Proper storage can extend their shelf life and ensure their performance.

[0003] However, when polyurethane adhesive is in contact with air during storage, it is easy for moisture to enter; in addition, if the polyurethane adhesive is stored for a long time, it may be delaminated or precipitated. However, in the prior art, when polyurethane adhesive is stored, it is easy to come into contact with air when it is taken out, and after long-term storage, it needs to be mixed and stirred to prevent precipitation. At this time, stirring with a stirring rod is likely to cause glue to adhere to the stirring rod, which is easy to cause waste. At the same time, it is impossible to ensure its sealing after opening the lid for use. Therefore, we propose a polyurethane adhesive holding device with strong sealing performance and easy stirring to solve the above problems. Utility Model Content
