Composite advanced material veneer ecological board and manufacturing method thereof

Abstract

The invention discloses a manufacturing method of a composite advanced material veneer ecological board. The manufacturing method of the composite advanced material veneer ecological board includes the following steps that step one, wood shavings or wood fiber is spread on one board surface of a solid wood veneer or technological wood veneer, and a wood shaving composite veneer, a wood shaving composite technology veneer, a wood fiber composite veneer or a wood fiber composite technology veneer are prepared after cold pressing and hot pressing; step two, an adhesion agent is applied on the upper board surface and the lower board surface of a joinery board or plywood to enable the wood shaving composite veneer, the wood shaving composite technology veneer, the wood fiber composite veneer orthe wood fiber composite technology veneer to be pasted on the upper board surface and the lower board surface of the joinery board or plywood, a slab is cold pressed and then hot pressed, and then after hot pressing, impregnated paper is pressed on the upper board surface and lower board surface to prepare the finished ecological board. The veneer ecological board prepared by the manufacturing method has good flatness, high surface adhesive strength, low water content, good performance of dimensional stability, crack resistance, cold and heat circulation resistance, and production costs canbe reduced.

Description

technical field [0001] The invention relates to the technical field of decorative ecological panels, in particular to a composite new material decorative ecological panel and a manufacturing method thereof. Background technique [0002] At present, in the domestic and foreign markets, the decorative materials of ecological panels mainly include: [0003] 1) Solid wood veneer with a thickness of 0.10-0.75mm, such as poplar, mahogany, and sophora japonica; [0004] 2) Integrated materials with a thickness of 0.2-0.6mm, such as technical veneer; [0005] 3) High-density fiberboard with a thickness of 1 to 3mm. [0006] The pressing process of the above-mentioned facing materials is as follows: the upper and lower surfaces of ordinary plywood or blockboard are glued, cold-pressed, hot-pressed and other processes are pressed to form the ecological board base material, and the upper and lower surfaces of the ecological board base material Press impregnated paper on the surface ...

AI Technical Summary

Problems solved by technology

[0007] This pressing process uses the ecological board base material pressed by the above-mentioned 1) and 2) two kinds of decorative materials, and presses the impregnated paper on the upper and lower board surfaces of the ecological board base material to make the finished ecological board, which has a smooth surface. Poor hardness, low surface bonding strength, high moisture content, dimensional stability, crack resistance, poor resistance to cold and heat cycles, etc.

[0008] Using the above-mentioned 3) ecological board base material pressed by the decorative material, the impregnated paper is pressed on the upper and lower board surfaces of the ecological board base material, and the finished ecological board is obtained, which has formaldehyde pollution, low surface bonding strength, and water absorption thickness expansion rate Larger, thicker, higher production costs, etc.
