Abrasive paper binder: Excellent application of synthetic resin

In the process of manufacturing sandpaper, the selection of binder is crucial. It not only determines the durability of sandpaper, but also directly affects its grinding effect and service life. Among many binders, synthetic resin has become the preferred material for sandpaper manufacturing due to its unique performance advantages.

Abrasive paper binders usually use synthetic resin as the main component, and this choice is not accidental. Synthetic resin, as a synthetic polymer compound, has a variety of excellent physical and chemical properties, especially its bonding performance, wear resistance and high temperature resistance, which plays a pivotal role in sandpaper manufacturing.

The bonding performance of synthetic resin is the key factor for it to become a Abrasive paper binder. In the manufacturing process of sandpaper, the sand grains need to be firmly adhered to the base paper to ensure that the sand grains will not fall off during the grinding process. Synthetic resin can form a strong bonding layer during the curing process. This bonding layer not only has strong adhesion, but also can adapt to the different materials and surface morphologies between the sand grains and the base paper, thereby achieving tight bonding.

In addition to the bonding performance, the wear resistance of synthetic resin is also one of the reasons why it is so popular. Sandpaper needs to withstand greater friction and pressure during use, so the adhesive must have good wear resistance. Synthetic resin is treated with a special process to form a hard protective layer after curing, which effectively resists wear during grinding and prolongs the service life of sandpaper.

In addition, the high temperature resistance of synthetic resin is also a highlight in sandpaper manufacturing. During the grinding process, a lot of heat will be generated between the sandpaper and the workpiece. If the adhesive cannot withstand high temperature, it will cause the sand particles to fall off or the adhesive to fail. Synthetic resin has excellent high temperature resistance and can maintain a stable bonding effect in a high temperature environment to ensure the normal use of sandpaper.

Among the types of synthetic resins, phenolic resin, furan resin and isocyanate are common resins used in sandpaper manufacturing. These resins can form different chemical structures and performance characteristics during the curing process to meet the different needs of sandpaper manufacturing. For example, phenolic resin has high strength and corrosion resistance, and is suitable for making sandpaper with high requirements; furan resin has good water resistance and oil resistance, and is suitable for making sandpaper for special environments; and isocyanate has excellent adhesion and chemical corrosion resistance, making it an ideal choice for making high-performance sandpaper.

As the main component of sandpaper adhesive, synthetic resin has excellent adhesion, wear resistance and high temperature resistance, and is an indispensable and important material in sandpaper manufacturing. With the advancement of science and technology and the continuous optimization of processes, the application of synthetic resin in sandpaper manufacturing will be more extensive and in-depth, bringing more convenience and benefits to industrial production and daily life.
