Problems solved by technology

The solid wood boards are made of natural materials, the resource is scarce and the price is high, the color is also determined by the tree species, there are few choices, and the environment that is too dry and humid is not suitable for solid wood, so it is more troublesome to maintain, and the acid and alkali resistance is poor; the current domestic cabinets There is still a gap between the technological level and the international level. The domestic solid wood door panels are not well-crafted, and problems such as deformation, cracking, and rough surface are prone to occur.

Abstract

The invention discloses a production method of a dedicated fireproof flame-retardant medium-density fiber cabinet board. The production method comprises the following steps: (1) raw material pretreatment; (2) sieving; (3) softening through stewing; (4) grinding; (5) gluing and drying; (6) prepressing; (7) hot-pressing; (8) sawing and sanding; (9) veneering hot-pressing; and (10) edge cutting, thereby obtaining the finished product. Eucalyptus bark, branches, and waste leftover materials left in plate manufacturing are used as main raw materials, and other weedtrees are added, so that waste isturned into wealth, and timber resources are sufficiently and effectively utilized; modified paraffin and a flame retardant urea resin adhesive are added, so that the fire resistance and the flame retardation performance are greatly improved, and the manufactured dedicated medium-density fiber cabinet board is high in fire resistance and the flame retardation performance, high in water resistance,and low in formaldehyde content, and is a safe and environmental-friendly dedicated cabinet board.

Description

technical field [0001] The invention belongs to the technical field of cabinet boards, in particular to a production method of a fireproof and flame-retardant medium-density fiber cabinet special board. Background technique [0002] Wood-based panels are boards or molded products that are made of wood or other non-wood plants, separated into various unit materials by certain mechanical processing, and glued with or without adhesives and other additives. It mainly includes three major categories of products: plywood, shaving (particle) board and fiberboard, with hundreds of extended products and deep-processed products. Plywood is made by steaming and softening logs, rotary cutting into large sheets, and then placing the wood fiber directions perpendicular to each other, bonding them with synthetic resin glue with good water resistance, and then pressurizing, drying, sawing, and surface trimming. of plates. The number of layers is an odd number, generally 3 to 13 layers, wh...
