Method for making composite wood door sheets

Abstract

The invention discloses a method for making composite wood door sheets, and relates to the technical field of building material machining. The method comprises the steps that a scraped car bumper plate is bonded between two base material layers with glue so that a composite man-made plate can be formed, core plates are formed by splicing finger joint battens in a bonded mode, the composite man-made plates are fixed to the upper surfaces and the lower surfaces of two or more core plates in the same direction in a bonded mode, a door sheet body is formed through cold pressing, wood veneers are bonded to the upper surface and the lower surface of the door sheet body, and a door sheet can be formed through pressure curing. Compared with the prior art, with the method, the current situation of the lack of high-quality timber is alleviated, scraped car dumpers which are hard to handle in the car industry can be recycled, the requirements for energy saving and environment protection are met, in addition, the door sheet has the external characteristics of raw wood doors, and is very competitive because of the low price, and because the composite man-made plates can be made just through overlap and cold pressing, the production technology is simple and high in efficiency; the door sheet has the good sound insulation effect, and is high in strength and applicable to the doors of boxes in entertainment venues.

Description

technical field [0001] The invention relates to the technical field of building material processing, in particular to a method for manufacturing a composite wooden door panel. Background technique [0002] With the rapid development of my country's economic construction and the continuous improvement of people's living standards, coupled with the rapid development of the construction industry and the furniture industry, the demand for wood has increased significantly. Therefore, the number of logs harvested is increasing. In order to maintain Ecological balance, the state advocates the vigorous development of new environmentally friendly materials, therefore, the development of the wood-based panel industry has effectively alleviated the consumption of wood in our country, and is an important way to save wood. [0003] In the furniture industry, as people have higher and higher requirements for doors, they require not only beautiful, environmentally friendly and lightweight, ...

Problems solved by technology

[0003] In the furniture industry, as people have higher and higher requirements for doors, they require not only beautiful, environmentally friendly and lightweight, but also moisture-proof, good sound insulation, and good rigidity; but with the increasing demand and the decreasing forest resources, especially precious Due to the lack of wood species, the contradiction between supply and demand of solid wood doors is becoming more and more prominent, and it is becoming more and more expensive. Therefore, people have developed methods for making wooden composite wooden door panels. These wooden composite wooden door panels have various structures and structures. Generally, it includes a skeleton and a panel in the middle. The panel is usually made of wood veneer. The sound insulation, moisture resistance and rigidity of pure wood veneer are not good enough; especially in entertainment places, music, karaoke, and noise all need good doors to block them.

[0004] Automobile bumper is a thin-arm structural part with large surface area and complex shape. It requires excellent high and low temperature impact toughness, rigidity, aging resistance, heat resistance and cold resistance. During the manufacturing process, there will be unqualified These bumpers are made of composite panels made of polyurethane elastomer and ABS. Due to some surface creases, dirt, color difference, and improper molding, they are scrapped and sent to landfill or incineration, which is very wasteful.
