Embodiment Construction

[0029] The following is the best embodiment of a wood substrate and polyurethane composite material and its manufacturing method described in the present invention, which does not limit the protection scope of the present invention.

[0030] Implementation one, with reference to Fig. 2, Fig. 3, provide a kind of wooden base material and polyurethane composite material, comprise wooden base material 5, be provided with one layer at least on the surface of described wooden base material 5 by adding organic solvent, color Coating 6 is formed by coating polyurethane slurry with materials and additives. The coating 6 is formed by coating polyurethane slurry on the release paper 7 and pasting it on the wooden substrate 5, then drying and cooling, and peeling off the release paper 7 to form a coating on the surface of the wooden substrate 5. The composite layer of polyurethane is formed from the coating 6 described above.

[0031] Various patterns, patterns or characters are also tr...

Abstract

The invention discloses a method for producing the composite material of wooden base and polyurethane, and relative production. The invention comprises a wooden base whose surface is disposed with at least layer of polyurethane slurry added with organic solvent, colorant, and agents. The invention coats polyurethane slurry on specific paper, adjusts the components of each coat, to produce the composite layer with different functions, to meet different demands. And since the specific paper is formed with paper or word, the specific paper can be removed after composing and shaping the composite layer and wooden base, to transfer pattern and word on the composite layer, with decorative function. The invention can be used to pattern paper, packing box, floor or the like.

Description

technical field [0001] The invention relates to a wood substrate and polyurethane composite material that can be used for producing patterned paper, packaging boxes, doors, furniture, floors, ceilings, etc., and also relates to a manufacturing method of the wood substrate and polyurethane composite material. Background technique [0002] The traditional transfer coating method is used to apply polyurethane to woven fabrics, knitted fabrics, non-woven fabrics or wet-process synthetic leather as substrates, and polyurethane is coated on it, because polyurethane (PU ) The surface of synthetic leather has a noble leather feel, waterproof and fireproof, and the surface of synthetic leather has various textures and other functions to meet the needs of the public. However, it has not been able to manufacture a wood-based substrate and a polyurethane composite material and a method for manufacturing the wood-based substrate and polyurethane composite material with the wooden materia...
