Melamine impregnated paper,also called Melamine-Urea-Formaldehyde Impregnated Bond Paper
Melamine-Urea-Formaldehyde Impregnated Bond Paper, also known as “melamine” paper, is a plain paper or printed decorative paper impregnated with amino resin (melamine formaldehyde resin and urea resin) and dried To a certain extent, with a certain resin content and volatile content of the adhesive tape, the hot can be glued to each other or with the man-made board substrate gluing
Main indicators of melamine impregnated film
A. Dip Amount: The content of the solid resin in the decorative film is expressed as a percentage (%). B. Volatile content: The content of volatiles (mostly moisture and other small molecules) in decorative film, expressed as a percentage (%). C. Pre-curing degree: the degree of curing of the resin in the decorative film, expressed as a percentage (%).
(Melamine formaldehyde resin and urea-formaldehyde resin mixture) → first drying → second impregnation (melamine formaldehyde resin) → second drying → Cooling cut.
Development of melamine impregnated paper
Melamine impregnated film is currently widely used in plate furniture, most of the low-pressure short-cycle form, that is, under high temperature and pressure, pressure tens of seconds to produce plate. In recent years, dipped paper film with steel plate wood produced by the synchronization of the flower plate, because of its good three-dimensional texture by people like. Melamine impregnated paper in the low temperature for a long time under pressure will form a high light plate, is also a lot of companies developed and improved.
In view of the requirements of surface plasticity and environmental protection, mainly the formaldehyde-free requirements, impregnated paper developed to finish the ink on the surface of the paper, and then coated with water-borne polyurethane resin on the surface, play a protective effect of scratch resistance; waterborne polyurethane resin coating After the paper surface, the paper can also be wrapped crimp, plasticity will be better than the previous;
1. beautiful material appearance effect, improve the use value. 2. Improve the physical performance and expand the scope of use. 3. Improve the value of wood-based panel. 4. Simplify the production process of wood-based panels (to avoid painting, brushing and other processes). With the lack of human timber resources and the pursuit of human demand for wood products, melamine impregnated paper in the 21st century will also be better development
