Rubber making → compounding (adding curing agent, release agent, etc.) → first impregnation (mixing of melamine formaldehyde resin and urea-formaldehyde resin) → first drying → second impregnation (melamine formaldehyde resin) → second drying → Cool crop.
Development of melamine impregnated paper
Melamine-impregnated adhesive film paper is currently commonly used in panel furniture, and most of them are in the form of low pressure and short cycle, that is, under high temperature and high pressure, they are laminated for several tens of seconds to obtain boards. In recent years, the synchronous facing board produced by impregnating the adhesive film paper with the wood grain of the steel plate has been favored by people for its good three-dimensional texture. Melamine-impregnated paper will form a high-gloss board under low temperature and long-term pressing, and it has also been developed by many companies.
In view of the requirements of surface plasticity and environmental protection, mainly formaldehyde-free requirements, impregnated paper has been developed to finish the ink on the paper surface, and then apply water-based polyurethane resin on the surface to protect it from scratches. After the paper surface, the paper can also be wrapped and curled, and the plasticity will be better than before.
Advantages of melamine impregnated paper
1. Appearance effect of beautiful materials, improve use value.
2. Improve physical properties and expand the scope of use.
3. Increase the value of wood-based panels.
4. Simplify the production process of wood-based panels (avoid painting, painting and other processes).
With the lack of human wood resources and the increasing demand for human pursuit of wood products, melamine-impregnated paper will certainly develop better in the 21st century.
