Embodiment Construction

[0040] The specific embodiment of the present invention is shown in accompanying drawing, it is characterized in that described solid wood sawn composite board is made up of solid wood veneer 1 and adhesive 2 sawn after multi-layer drying; Aligned and tiled, solid wood veneers 1 are bonded by adhesive 2 to form a single-layer solid wood board 3; 3 layers of single-layer solid wood boards 3 are bonded by adhesive 2 and compacted into a multi-layer solid wood saw Cut composite board.

[0041] The fiber direction of the two-layer single-layer solid wood board 3 adjacent to the solid wood sawing composite board is laminated vertically or parallel to the dislocation lamination; the adhesive can use different types of glue according to different needs, such as urea-formaldehyde glue, phenolic glue, Modified melamine glue, etc.

[0042] The thickness of the solid wood veneer 1 is above 2mm.

[0043] The processing technology of solid wood sawing composite board, its technological p...

Abstract

The invention discloses a solid wood sawed composite board and a machining process, and relates to the solid wood sawed composite board which is used in industry, agriculture, building material industry and furniture industry. The solid wood sawed composite board is characterized by consisting of a plurality of layers of dried and sawed solid wood veneers and an adhesive, wherein the solid wood veneers are trimmed and then aligned and tiled; the trimmed edges of the solid wood veneers are adhered into a veneer solid wood board through the adhesive; two to nine veneer solid wood boards are adhered through the adhesive and are compacted into a multi-layer solid wood sawed composite board; and fibers of two adjacent veneer solid wood boards of the solid wood sawed composite board are laminated in vertical direction or laminated and adhered in a parallel or staggered way. The process flow of the machining process comprises the following steps of: drying the board; sawing the veneer; performing secondary balancing on the veneer; trimming; placing in a balanced staggered way, placing in a cross vertical mode and coating the adhesive; performing cold pressing or hot pressing adhesion; sanding and trimming; and finishing. The solid wood sawed composite board has the characteristics of novel structure, easiness and convenience in machining, non-deformation, less using amount of the adhesive, environmental friendliness, health and the like.

Description

technical field [0001] The solid wood sawn composite board and processing technology described in the present invention relate to a solid wood sawn composite board used in industry, agriculture, building material industry and furniture industry. Background technique [0002] At present, the widely used wood products are mainly plywood, MDF, blockboard, glulam and so on. Among them, density board blockboard is not in the category of solid wood. Due to the high price and limited scope of application of glulam, plywood is the main application. Taking plywood as an example, plywood is a three-layer or multi-layer board-shaped material made of wood sections that are steamed and then sliced ​​into veneers or sliced ​​into thin wood, and then glued with adhesives. , and make the fiber directions of adjacent layers of veneers perpendicular to each other and glue them together. Generally, the thickness of the veneer is below 2mm. First of all, the logs used in the rotary-cut vene...
