Problems solved by technology

[0002] Adhesives play the role of connecting objects by surface bonding through adhesion and cohesion. They have the characteristics of continuous stress distribution, light weight, or sealing, and most of the process temperatures are low. Following the current demand for adhesives in many fields It is getting higher and higher, and there is a gap between people's understanding of adhesives and their preparation methods. According to the materials used and the preparation process, the effect of subsequent use of adhesives will also change, and the adhesives will vary according to the environment in which they are used. Different adhesives have different adhesive effects. Among them, the existing adhesives cannot fully dissolve a variety of materials well during the preparation, resulting in a decline in the performance of the adhesive when used later, and the existing organic solvents Most are flammable, posing an ignition or explosion hazard during preparation
