Low-carbon method for manufacturing environmental friendly deformation-prevention fireproof sheet material

Abstract

The invention discloses a low-carbon method for manufacturing an environmental friendly deformation-prevention fireproof sheet material. Timber resources are not inexhaustible, so that the problems of large demand and high cost of the timber resources occur. The method includes the following steps that a raw wood is cut into veneers in a rotary mode through a rotary cutter, and the veneers are divided into grades and dried until the moisture content is lower than 12%; surface layers and a middle layer are coated by glue and then pressed to form a composite board, and the composite board is cut into laths of the same specification; three layers of laths with arrayed transverse textures are selected, one layer is placed in the middle layer, and the other two layers of the laths with the arrayed transverse textures are placed into the surface layers or inner layers of the surface layers, and a deformation-prevention sheet material is formed through a hot press in a pressing mode; the deformation-prevention sheet material is stored more than 15 days in a standing mode for conditioning, cut into wide laths according to a fixed length, coated by glue and then manufactured to be a deformation-prevention board through an automatic board jointing machine; the redundant four sides of the deformation-prevention board are cut off, and sanding is performed through a sanding belt; the deformation-prevention sheet material is soaked in a fire retardant and coated by dry oil. Common timber resources are fully used for replacing valuable timber resources, so that the resources are saved, waste is made to be profitable, forest resources are effectively protected, and cost is reduced.

Description

technical field [0001] The invention relates to a production technology of an anti-deformation board, in particular to a low-carbon method for manufacturing an environment-friendly anti-deformation fireproof board. Background technique [0002] At present, during the processing of plywood factories, veneer factories, and multi-layer board factories, some second- and third-grade veneers are rarely used due to factors such as uneven thickness, abnormal color, excessive scarring, and non-environmental protection, and some are used for low-grade veneers. The plywood is used for one time, and part of it is used as a garbage storage corner. In the end, we often worry about not being able to find customer resources. After a long time, it will become moldy and deteriorated. It can only be burned as a burning material, which not only pollutes the environment, but also greatly wastes wood. Resources, the core materials commonly used in wooden doors on the market are mostly filled with...

Problems solved by technology

[0005] The present invention aims at the problems of high production cost, non-environmental protection, damage to human body, etc., and provides a low-carbon method for making environmentally friendly and anti-deformation fireproof boards, which can be compared Solve the above problems well, make full use of artificial rapid-growing forests and the remaining secondary and tertiary waste materials in veneer factories, thereby saving resources, realizing turning waste into treasure, and effectively protecting forest resources; reducing costs and meeting low-cost Carbon development requirements, with good market application prospects
