Description

Flame-retardant medium-high density fiberboard
Technical Field
The invention relates to the technical field of plates, in particular to a flame-retardant medium-high density fiberboard.
Background
The fiberboard is also named as a density board, which is an artificial board made of wood fiber or other plant cellulose fiber as a raw material and urea formaldehyde resin or other suitable adhesives. During the manufacturing process, adhesives and/or additives may be applied. The fiber board has the advantages of uniform material, small longitudinal and transverse strength difference, difficult cracking and the like, and has wide application. The 1 cubic meter fiberboard needs 2.5 to 3 cubic meters of wood to manufacture, and can replace 3 cubic meters of sawn timber or 5 cubic meters of log. The development of fiberboard production is an effective way for the comprehensive utilization of wood resources. The fiber board has the defects that the surface areas of the two sides of the board are different due to the reticulate pattern on the back surface, and the board is warped and deformed due to the difference of expansion force generated after moisture absorption; the hard board has hard surface, difficult nailing and poor water resistance. Dry-laid fibreboards, while avoiding some of the disadvantages, are relatively expensive.
The basic unit constituting a fiberboard is a separate wood fiber or fiber bundle. The raw materials for preparing the fiber mainly come from forest logging residues, such as branches, tips, small logs and the like; and wood processing residues such as board edges, shavings, sawdust, and the like. In addition, the waste of forest chemical processing (such as tannin extract and hydrolyzed residue) and other plant stems can be used for preparing fiber. The needle wood has high fiber content, and the fiber length is 30-50% longer than that of the broad-leaf wood. If broad-leaved wood is used, the treatment is carried out firstly: the method can be used for pulping by mixing needle and broad wood, or treating wood chips by chemical method, or using hot water and steam. Before the fiber separation, the raw material is sliced into thin slices with the length of 20-30 mm, the thickness of 3-5 mm and the width of 15-25 mm by a slicing machine. The wood chips are too large, and are difficult to soften or not softened uniformly in the preheating treatment and pulping processes, and the fiber separation degree is low; too short wood chips result in a large proportion of cut fibers and poor interlacing properties, resulting in a decrease in the strength of the fiberboard. The cut wood chips are sent into a storage bin after the processes of screening, crushing, washing and the like for fiber separation.
The density fiberboard of fire resistance is too single at present, the fire behavior of fiberboard is more general, can not show obvious fire-retardant to the naked light, can't make the fiberboard protect to the side in use, the side produces the burr easily in long-term use, and the fiberboard is easy to produce when receiving the striking cracked, not only influence the pleasing to the eye of fiberboard, also cause certain influence to the use of fiberboard, and the waterproof performance of fiberboard is relatively poor, the fiberboard can absorb the moisture in the air in long-term use, thereby lead to the fiberboard to produce the rotten condition, influence the life of fiberboard, we propose a fire-retardant type medium and high density fiberboard for this reason.
