A preparation method of thin-strip solid wood composite integrated board

Abstract

A manufacture method of a thin strip type solid wood compound laminated panel includes the steps that multiple composite boards are compounded to form thin strip type compound laminated timber, then, the thin strip type compound laminated timber is sawn into thin strip type solid wood composite board square strips with the thickness meeting the requirement, and then the multiple thin strip type solid wood composite board square strips are spliced to form the thin strip type solid wood compound laminated panel. In the manufacture method, raw materials of the first composite boards and the second composite boards are each formed by directly planing a thin strip (with the diameter being 2-3 CM) cylindrical wooden core shaft through a low-power simple matcher to form four extremely small parts of planes; and machining is easy, the energy consumption is low, and the timber utilization rate is high. Each of connection faces of the first composite boards and the second composite boards is a wave type cambered surface. When the two types of boards are compounded, the splicing and bonding areas of the boards are larger, and bonding of the boards is firmer. After the first composite boards and the second composite boards are compounded and spliced, existing splicing points of the first composite boards and the second composite boards are bonded in a staggered manner, and the strength of the panel is improved. Requirements of different industries and different fields for laminated panels of different specifications are met.

Description

technical field [0001] The invention belongs to a novel wood-based panel, and in particular relates to a preparation method of a thin-strip solid wood composite integrated panel. [0002] technical background [0003] There are many manufacturers of veneer and plywood in our country, but there are a huge number of thin strips (diameter 2-3CM) of cylindrical wooden mandrels remaining in the production of veneer and plywood. Increasing income and increasing the supply of wood-based panels are problems that wood-based panel manufacturers need to solve urgently. [0004] Due to the immature processing technology for the reuse of thin cylindrical wood mandrels in the manufacture of high-end solid wood glulam, wood mandrels are still mostly incinerated or processed into wood chips for the production of fiberboards, and only a small part of them are used in the production of broom handles and relatively Low-end low-strength, low-toughness solid wood glulam. [0005] At present, wh...

Problems solved by technology

[0005] At present, when the above-mentioned wooden mandrels are applied to the preparation of solid wood glulam, the traditional four-sided planing equipment is mainly used to plan the thin cylindrical wooden mandrels into square-shaped small squares with lines on all sides for production and utilization. , mechanical wear and consumption of raw materials are extremely high, processing costs are high, and finished products have shortcomings such as unstable performance and high cost

[0006] At the same time, when the above-mentioned wooden mandrel is used as raw material to produce traditional solid wood glulam, the finished product still has the following technical defects: ① Due to the natural lack of tensile force in the wood pith of the wood mandrel, the synthetic finished product is very easy to be trapped in the wood pith. The center part is cracked, causing the product to be damaged and scrapped; ② Due to the traditional planar splicing method, the bonding strength is weak due to the limitation of the bonding area between the wood beams, and the finished product is also prone to cracking, loose strips, etc.

Then affect the quality of glulam
