The invention relates to 3D stereo
melamine decorative paper. A transparent PE layer is arranged on a raw paper layer, and the upper part of the PE layer is provided with 3D
printing ink. A preparation process for the decorative paper comprises the following concrete procedures: (1)
coating printable decorative raw paper with a layer of PE at first; (2) carrying out surface
corona treatment on the PE-coated decorative raw paper so as to allow the PE-coated decorative raw paper to meet requirements of ink printing on adhesion; (3) carrying out full-page printing, wherein since the
printing ink contains magnetic pearl
powder, a
magnetic field generated in a printing support die has adsorption capacity to the
printing ink, and magnetic force controls movement of
magnetic powder to produce a pattern designed in advance; and (4) after shaping of the pattern, allowing the decorative paper to enter a
drying system and carrying out curing and setting so as to obtain the 3D stereo
melamine decorative paper. The technology used in the invention overcomes the insufficiency that traditional intaglio printing technology cannot achieve stereo effect even after multi-time planar color register; and the 3D stereo
melamine decorative paper allows panel furniture, wood floors,
doors and the like produced from wood-based plates to achieve brand new three-dimensional visual
impact and substantially improves novelty and beauty of the decoration industry.
