Problems solved by technology

[0004] Most of the existing artificial veneers are made of ordinary rubber wood or pine front core. This kind of veneer is prone to deformation, and the yield rate is low, which is generally 30-40% in the industry. Therefore, its production The finished veneer is not only more expensive, but also difficult to guarantee the quality

Embodiment 1

[0026] refer to figure 1 Shown, a kind of preparation technology of rubberwood front core comprises the following steps:

[0027] 1) Process the spliced ​​surface of the rubber wood core into a straight sawtooth shape;

[0028] 2) Coat hot-melt adhesive on the spliced ​​surface of the rubber wood board core. The coated hot-melt adhesive is composed of the following raw materials in weight percentage: 30% formaldehyde, 40% urea, 25% melamine, 1% caustic soda, polyvinyl alcohol 2%, curing agent 2%, and after coating, make more than one layer of rubber wood core two by two to form a rubber wood board;

[0029] 3) Stack the assembled rubber wood boards in an environment with a temperature of 30°C and a humidity of 70%, and place them for 5-7 days until the moisture content of the rubber wood boards is 6%;

[0030] 4) Coat the surface of the stacked rubber wood board with a layer of putty, then scrape it flat, and sand it once to get the rubber wood front core.

Abstract

The invention discloses a rubber wood front core preparation process and application thereof. The preparation process comprises the following steps: 1) rubber wood plate core assembled surfaces are machined in a sawtooth form; 2) hot melt adhesive is coated on the rubber wood plate core assembled surfaces; and more than one layers of rubber wood plate cores are pairwise assembled to form rubber wood plates after coating; 3) the assembled rubber wood plates are flatly stacked in an environment with a temperature of 25-30 DEG C and a humidity of 60-70% for 5-7 days; and 4) putty layers are coated on the surfaces of the stacked rubber wood plates, are flatly scraped, and are sanded once to obtain rubber wood front cores. The rubber wood front core preparation process and the application thereof can improve the veneer production yield, reduce the cost, and guarantee the quality.

Description

technical field [0001] The invention belongs to the technical field of plate processing, and in particular relates to a preparation process and application of a rubber wood front core. Background technique [0002] Veneer, the full name of decorative veneer veneer plywood, it is a surface for interior decoration or furniture made by cutting natural wood or technical wood into thin slices of a certain thickness, adhering to the surface of plywood, and then hot pressing Material. [0003] Common veneers are divided into natural wood veneer veneers and artificial veneer veneers. The difference in appearance between artificial veneer veneer and natural wood veneer is that the texture of the former is basically a straight texture or a regular pattern; while the latter is a natural wood pattern with a natural texture pattern, relatively large variability, and irregular. Its characteristics: it not only has the beautiful pattern of wood, but also fully utilizes wood resources and...
