Composite door board

Abstract

The invention discloses a composite door board and relates to the technical field of building material processing. The composite door board comprises a face board, the face board comprises a board core formed by splicing two or more than two finger joint battens, and a layer of composite artificial board is arranged on each of the upper surface and the lower surface of the board core. Each layer of composite artificial board comprises two base material layers, and a soundproof layer is arranged between the base material layers by means of gluing and is a foam layer made of a used foam mattress. A veneer layer wraps the composite artificial boards. Compared with the prior art, the composite door board has the advantages that the current situation that existing high-quality timbers are in shortage is mitigated, and used foam mattresses difficult to treat and discarded by people can be recycled, so that the requirements of energy conservation and environmental protection are met; the composite door board has the external characteristics of a log door and is low in price, thereby enabling a product to be quite competitive; the composite artificial boards can be produced only by laminating and cold pressing, and accordingly, production technology is simple and efficiency is high; the composite door board is good in soundproofing effect and high in strength, thereby being applicable to doors of boxes of entertainment places.

Description

technical field [0001] The invention relates to the technical field of building material processing, in particular to a composite 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, but also moisture-proof, good soun...

AI Technical Summary

Problems solved by technology

The foam layer in the foam mattress is mainly polyurethane foam. Polyurethane foam has ultra-low temperature thermal conductivity, weather resistance and heat preservation; high-efficiency insulation, sound insulation, waterproof and moisture-proof characteristics; but people have the habit of liking the new and disliking the old, and seeing more and more new mattresses Even if the old mattresses in use are not broken, they must be discarded and replaced with new ones, or all old mattresses will be replaced due to moving to a new house, so many mattresses that are not broken are discarded and taken to landfill or incineration , very wasteful
