To understand the reason for the long-lasting adhesive property of tape, we first need to know the basic structure of tape. Generally speaking, tape is composed of substrate, adhesive, release paper and other parts. Among them, the adhesive is the key factor that determines the adhesive property of tape. II. Types and characteristics of adhesive The adhesive is the core part of the tape, and its type and characteristics directly affect the adhesive property and durability of the tape. Modern adhesives mostly use synthetic rubber or polymer macromolecular materials, which have good adhesion and durability. In addition, some auxiliary materials such as viscosity enhancer, thinner, anti-aging agent will be added to the adhesive to improve its performance. III. The reason for long-lasting adhesive property 1. Selection of macromolecular materials: Synthetic rubber or polymer macromolecular materials have good elasticity and extensibility, which can adapt to the surface shape of the adherend to a certain extent, thereby improving the tightness and durability of the bonding. 2. Rational formula design: Through scientific proportioning, various auxiliary materials are mixed with the main material to make the adhesive have good adhesion and durability. In addition, a reasonable formula can also improve the anti-aging performance of the tape so that it can maintain good adhesion in harsh environments. 3. Appropriate production process: The production process of tape also has a great influence on its adhesive property and durability. In the production process, by controlling temperature, pressure, time and other parameters, the adhesive and substrate are closely combined to form a uniform and continuous glue layer. In addition, appropriate coating technology and drying process can also improve the adhesive property and durability of the tape. IV. Summary In summary, the long-lasting adhesive property of tape mainly depends on the selection of macromolecular materials, rational formula design, and appropriate production process. These factors work together to enable the tape to maintain good adhesion and durability in various environments. Understanding these key factors can help us better choose and use tape to improve work efficiency and quality of life.
