From the fundamental start, understand the preparation principle of solvent-free polyurethane adhesive
As a kind of green adhesive, solvent-free polyurethane adhesive has attracted much attention in recent years. So, solvent-free polyurethane glue is how to prepare it? Today we start from the fundamental, to understand the principle of preparation of solvent-free polyurethane glue.
First of all, the main raw materials in the preparation process of solvent-free polyurethane adhesive are isocyanate and polyol. By reacting these two materials under specific conditions, a solvent-free polyurethane adhesive can be prepared. This reaction process needs to be carried out without solvent, so it is called solvent-free polyurethane glue.
The preparation principle of solvent-free polyurethane adhesive is relatively simple, but the key is to control the reaction conditions and the proportion of materials. Only under suitable temperature, pressure and time, isocyanate and polyol can be fully reacted to form a solvent-free polyurethane adhesive with good performance.
In addition, the preparation process of solvent-free polyurethane adhesive also needs to add some additives, such as catalysts, stabilizers, etc., to improve the performance and stability of the adhesive. These additives play a vital role in solvent-free polyurethane adhesives and can effectively improve the use of adhesives.
All in all, understanding the preparation principle of solvent-free polyurethane adhesives is of great significance for the production and application of solvent-free adhesives. By mastering the preparation principle, we can better select the appropriate materials and control the production process, so as to produce high quality solvent-free polyurethane adhesive, which will help the development of environmental protection industry.
