Problems solved by technology

[0005] However, in the process of glulam processing, there are many production processes, many glue materials, high cost, and most of the wood glue has a strong odor, which is not environmentally friendly and will cause secondary pollution. To solve this problem, there are currently many glues on the market. For example, Chinese patent CN 103692503 B discloses compressed glulam and a production method for compressed glulam. In this method, the unidirectional pressure of the traditional wood-based panel press is pressurized on all sides of the mold and the front and rear wooden materials are extruded each other, that is, the raw material The six sides are compressed, deformed, and bonded to each other to achieve the utilization of wood and bamboo. However, using this solution cannot solve the secondary utilization of the processing waste of the board, and the use of the board without pretreatment is not suitable for mass production. Moreover, The wood in this scheme is stacked irregularly, and the thickness and width of the boards cannot be controlled. Again, this scheme does not disclose the formula of glue

Abstract

The invention relates to the technical field of wooden material processing, and in particular relates to manufacturing method of waste laminated wood. The method comprises the following steps: processing the waste wood into modeling sticks with unified specifications, connecting as a strip plate by use of a plane structure between the sticks, thereby forming the stable connection force between the plates by use of the engaging capacity between cambered surfaces of the strip plates, wherein the connection force is used for modeling, the laminated wood is uniformly forced while increasing the fastening capacity between the laminated woods, and the warp is avoided; due to the unique modeling structure disclosed by the invention, the acting force between the plates is increased so as to correspondingly reduce the dependence to the glue, the glue usage amount is greatly lowered; and meanwhile, the conventional glue is improved so as to effectively adhere the wood; the laminated wood achieves the aims of strong in compressive resistance and less in glue dosage amount; the waste is sufficiently utilized, the used environment-friendly glue can effectively lower the glue peculiar smell, and lighten the secondary pollution to the environment.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of wood material processing, in particular to a method for making waste glulam. [0003] 【Background technique】 [0004] Guangxi is an important producing area of ​​eucalyptus. Eucalyptus is widely planted due to its fast growth, extremely short rotation period, strong adaptability, and few pests and diseases. Therefore, eucalyptus is often used in papermaking and furniture processing. However, eucalyptus is processed into wood boards In the end, there will be a lot of scraps, these wastes are often used for papermaking, and the profit is greatly reduced. Therefore, in the process of waste utilization of eucalyptus, it is processed into another way of waste utilization. Glulam is to make the wood texture parallel The solid wood boards and slats are extended in length and widened in width, and glued together to form wooden structural boards or squares of a certain shape and size. Since the glulam main...
