Example Embodiment

[0029] Example one

[0030] The preparation method of water-based isocyanate glued recombinant decorative material includes the following steps:

[0031] (1) Rotary cut logs to make veneer 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 defects of the veneer or the different good parts of the veneer After digging and repairing, a concave hole is formed. After pressurization and curing, the thickness of the veneer is in an uneven state in the part where the concave hole is located. 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 bonding between the veneers is more uniform and natural; the excavation and repair use art blades for excavation and repair or electric grinders for excavation and repair, which have a spherical sand head;

[0037] The preparation method of water-based isocyanate glued recombinant decorative material includes the following steps:

[0038] (1) Rotary cut logs to make thin wood veneer with a thickness of 0.7mm; the moisture content of the veneer is controlled at 16%; the veneer is repaired by digging and repairing the natural defects of the veneer or the different good parts of the veneer After digging and repairing, a concave hole is formed. After pressurizing and curing, the thickness of the veneer is in an uneven state where the concave hole is located. 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 bonding between the veneers is more even and natural; the excavation and repair use art blades for excavation and repair or use electric grinders for excavation and repair, which has a spherical sand head;

[0044] The preparation method of water-based isocyanate glued recombinant decorative material includes the following steps:

[0045] (1) Rotary cut logs to produce veneer with a thickness of 0.5-0.7mm; the moisture content of the veneer is controlled at 6-16%; the veneer is good for natural defects or different veneers. The parts are excavated and repaired, and a concave hole is formed after the excavation and repair. After the pressure curing, the thickness of the veneer is in an uneven state where the concave hole is located, and several veneers have different colors; the edge of the concave hole and the veneer body Transition through the slope between. By setting the slope, the bonding between the veneers is more uniform and natural; the excavation and repair use art blades for excavation and repair or use electric grinders for excavation and repair, which has a spherical sand head;

Abstract

The invention relates to a preparation method for recombining a decoration material through gluing of waterborne isocyanates, and belongs to the technical field of new decoration materials. The preparation method includes the following steps that (1) a log is rotationally cut, veneers with the thickness being 0.5-0.7 mm are manufactured; (2) the veneers are dried, whitened, dyed and dried again, so that primary sheets are obtained; (3) the primary sheets are glued and recombined, and a batten is obtained; and (4) the batten is subjected to cold pressing to form the recombined decoration material. In the step (3), a double-component waterborne polymer isocyanates (API) adhesive is used as the adhesive for gluing, the double-component waterborne isocyanates adhesive comprises a main agent and a curing agent which are compounded, and the main agent comprises, by weight, 100 parts of polyvinyl acetate emulsion, 0.01-0.1 part of an antifoaming agent, 10-13 parts of protective colloid, 0.05-0.5 part of a thickening agent and 5-8 parts of auxiliaries; the curing agent comprises isocyanates. According to the recombined decoration material, the formaldehyde emission is lower than 0.3 mg/L, gluebond strength is qualified, and color fastness to light reaches the level 4.

Description

technical field [0001] The invention relates to a method for preparing a water-based isocyanate glued recombined decorative material, which belongs to the technical field of new decorative materials. Background technique [0002] With the implementation of the "Natural Protection 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. The 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 timber felling along the railway line, the continued increase in output will be substantial. Increased costs, Russia's timber exports have shrunk sharply. On the contrary, consumers' consumption concep...
