1. Overview of urea-formaldehyde resin (UF)
Urea-formaldehyde resin, referred to as UF, is commonly used for bonding wood and has promoted large-scale applications in the production of plywood and particleboard.
2. Characteristics
Urea-formaldehyde resin is favored for its abundant raw materials and low price. It has excellent adhesiveness, is resistant to weak acids and weak alkalis, and exhibits good insulation and wear resistance. However, it is worth noting that formaldehyde is released during its curing process, and its heat resistance and aging resistance are relatively weak.
3. Form
Urea-formaldehyde resin can be presented in various forms such as resin, powder, board and adhesive to meet different application requirements.
4. Applicable processes
Urea-formaldehyde resin is suitable for various processes such as coating and compression molding, providing support for the manufacture of various products.
5. Application
As the most widely used glue in the wood processing industry, urea-formaldehyde resin is widely used in the bonding of wood, plywood, laminates, and bamboo and wood products. For example, it is used to make wooden shells of floors, furniture, packaging boxes, textile equipment, and household appliances.
1. Enhance the water resistance of urea-formaldehyde resin adhesive: By adding cross-linking agents such as aluminum sulfate and aluminum phosphate, its water resistance can be effectively improved.
2. Improve aging resistance: Mixing some thermoplastic resins into urea-formaldehyde resin adhesives can significantly improve their aging resistance.
3. Reduce formaldehyde content: By adjusting the synthesis process, reducing the molar ratio of formaldehyde to urea, or adding formaldehyde scavengers (such as urea, melamine, etc.), the purpose of reducing the formaldehyde content in urea-formaldehyde resin adhesives can be achieved.
