melamine impregnated paper

Melamine impregnated paper

The full name of melamine impregnated paper is melamine urea formaldehyde impregnated bond paper, also known as "melamine" paper. It is a kind of plain base paper or printing decorative paper, which is impregnated with amino resin (melamine formaldehyde resin and urea formaldehyde resin) and dried to a certain extent, and has a certain resin content and volatile content. After hot pressing, it can be glued to each other or with wood-based panel substrate.

Main indicators
A. Dipping amount: the content of solid resin in decorative adhesive film paper, expressed in percentage (%).
B. Volatile matter content: the content of volatile matter (mostly moisture and other small molecules) in decorative adhesive film paper, expressed as a percentage (%).
C. Pre solidifying degree: the curing degree of resin in decorative adhesive film paper, expressed in percentage (%).

Manufacturing process
Glue making → glue preparation (adding curing agent, release agent, penetrant, dust remover, etc.) → first impregnation (mixing melamine formaldehyde resin and urea formaldehyde resin) → first drying → second impregnation (melamine formaldehyde resin, wear-resistant layer) → second drying → cooling and cutting.

Development history
Melamine impregnated adhesive film paper is widely used in panel furniture. Most of it is in the form of low pressure and short cycle, that is, the plate is made by pressing for tens of seconds under high temperature and high pressure. In recent years, the synchronous pattern plate produced by impregnated plastic film paper and steel plate wood grain is deeply loved by people because of its good three-dimensional texture. Melamine impregnated paper will form high gloss plate under low temperature and long-time pressing, which has also been developed and improved by many companies.
In view of the requirements of surface plasticity and environmental protection, mainly formaldehyde free requirements, impregnated paper is developed to finish printing ink on the paper surface, and then coated with waterborne polyurethane resin on the surface to play the role of scratch resistance protection; After the waterborne polyurethane resin is coated on the surface of the paper, the paper can also be coated and curled, and the plasticity will be better than the previous ones;

Product advantages
1. Beautiful material appearance and improve the use value. 2. Improve physical properties and expand the scope of use. 3. Improve the value of wood-based panel. 4. Simplify the production process of wood-based panel (avoid painting, brushing and other processes). With the scarcity of human wood resources and the increase of human demand for wood products, melamine impregnated paper will also get better development in the new century.
