[0027] Example 1

[0028] The preparation method of the reconstituted decorative material comprises the following steps:

[0029] (1) Rotate the log to make veneer with a thickness of 0.5mm; the moisture content of the veneer is controlled at 6%; the veneer is repaired by digging and repairing the natural defect parts of the veneer or different good parts of the veneer , after digging and repairing, a concave hole is formed. After pressure curing, the thickness of the veneer is unbalanced in the part where the concave hole is located, and several veneers have different colors; the edge of the concave hole and the veneer body pass through the slope. transition. By setting the slope, the veneer can be fitted more evenly and naturally; for excavation and repair, use a utility blade for excavation and repair or use an electric grinder for excavation and repair, and the electric grinder has a spherical sand head;

Abstract

The invention relates to a preparation method for a reassembled decorative material, and belongs to the technical field of novel decorative materials. The preparation method includes the following steps that (1) a log is rotationally cut to manufacture thin wood veneers, the portions, with natural defects, of veneers or different good portions of the veneers are dug to form concave holes, the thickness of the veneers is in an unbalanced state on the local portions where the concave holes are located after pressurization maintenance, and the multiple veneers have different colors; a slope transition mode is adopted between the edges of the concave holes and veneer bodies; (2) the thin wood veneers are dried, bleached, dyed and dried again, so that primary plates are obtained; (3) the primary plates are glued and reassembled to obtain a batten; adhesives used during gluing are double-component aqueous polymer isocyanate (API) adhesives; and (4) the batten is subjected to cold pressing, then an antibiotic paint surface is prepared, and the reassembled decorative material is formed. According to the reassembled decorative material, the formaldehyde emission amount is lower than 0.3 mg/L, dipping peel strength is qualified, and the light color fastness can reach level 4.

Description

technical field [0001] The invention relates to a preparation method of a reconstituted decorative material, which belongs to the technical field of new decorative materials. Background technique [0002] With the implementation of the "Tianbao Project", stricter logging bans have been gradually implemented across the country. Taking Heilongjiang Province as an example, the logging volume in 2011 dropped sharply from 4.4 million cubic meters to 900,000 cubic meters. Supply is very tight. At the same time, looking at the world, foreign markets generally adopt a policy of restricting the export of timber. Taking Russia, the main importer of timber in my country as an example, with the multiple adjustments of tariffs and the completion of logging along the railway line, the continued increase in output will greatly increase the output. Increasing costs, Russia's timber exports have shrunk sharply. On the contrary, consumers' consumption concept has gradually returned to its or...
