Embodiment 1
[0052] After preparing the material, calculate by weight: add 20% softwood pulp fiber, 20% hardwood pulp fiber, 10% polyester fiber (1.67D, 6mm), and control the online concentration at 0.38%-0.42%, quantitative 180g / m 2 .
[0053] Glue inside the machine 180g / m 2 . Coating liquid formula: 25 parts of acrylic latex (SJ-2), 25 parts of acrylic latex (R959), and the index of paper is as follows:
[0054] Quantitative 360g / m 2 , thickness 39S, longitudinal tensile strength 1.4KN / m, transverse tensile strength 0.7KN / m.
[0055]After pressing the board, the bonding force is good, there is no delamination phenomenon, and there is no wood silk grain contrasting to the decorative layer.
Embodiment 2
[0057] After preparing the material, calculate by weight ratio: add 15% softwood pulp fiber (25D 30mm), 20% hardwood pulp fiber, 15% polyester fiber (6D, 12mm) online concentration is controlled at 0.38%-0.42%, quantitative 200g / m 2 .
[0058] Glue inside the machine 190g / m 2 . Coating liquid formula: 25 parts of acrylic latex (SJ-2), 25 parts of acrylic latex (R959), and the index of paper is as follows:
[0059] Quantitative 390g / m 2 , thickness 39S, longitudinal tensile strength 1.6KN / m, transverse tensile strength 0.92KN / m.
[0060] After pressing the board, the bonding force is good, there is no delamination phenomenon, and there is no wood silk grain contrasting to the decorative layer.
