Zusammenfassung:The solution concerns a board composed by a surface treatment component, impregnated with melaminoformaldehyde resin, and an inner layer component, impregnated by modified phenol formaldehyde resin. Both layers are pressed together. The phenol formaldehyde resin is modified by a mixture of N-hydroxymethyl-3-dimethoxyphosphorylpropionamide and hexamethylenetetramine in the ratio of 1:0.2 to 0.4:0.02 to 0.04, while the applied amount of modified resin ranges from 35 to 70 percent by weight, related to the paper weight.
