Flame-retardant wooden building board

Abstract

The invention discloses a flame-retardant wood building board, and belongs to the technical field of flame-retardant boards. The flame-retardant wood building board can drive a water net to be damaged after a high-temperature-resistant layer on the surface of an outer board is damaged, so that water in the water net flows out to dissolve a water-soluble film on the surface of a repairing ball, and the repairing ball can be repaired after losing the constraint of the water-soluble film. Under the action of internal gas, a pit is expanded, so that the high-temperature-resistant coating in the pit leaks out and fills a broken part of the high-temperature-resistant coating, and an automatic repairing function is realized; when the high-temperature-resistant coating loses efficacy and the outer board burns, at the moment, the repairing ball is broken, so that the water ball in the repairing ball leaks out, the water ball is exploded when making contact with fire, water in the repairing ball is sprayed out to play a fire extinguishing role, rod glue for connecting a main board and the outer board is softened, ammonium carbonate in the main board is heated and decomposed to generate gas, an elastic film expands, the outer board is pushed away, and the outer board is separated from the main board; and further loss expansion caused by combustion of the main board along with the outer board is avoided.

Description

technical field [0001] The invention relates to the technical field of flame-retardant boards, more specifically, to a flame-retardant wooden building board. Background technique [0002] Boards are standard-sized flat rectangular building material panels used in the construction industry as components for walls, ceilings or floors. Wood has a high hydrocarbon content and is a flammable material. The requirements for flame retardancy of the board are to reduce the burning rate of wood, reduce or retard the speed of flame propagation and accelerate the carbonization process of the burning surface, which is very important for industrial sectors such as construction, shipbuilding, and vehicle manufacturing. [0003] During the use of existing wooden boards, only a layer of high-temperature resistant coating is applied on the surface to play a fireproof role, but the coating is thin, and it is easy to lose the protective function of the board due to scratches and damage. Under ...

Problems solved by technology

[0003] During the use of existing wooden boards, only a layer of high-temperature resistant coating is applied on the surface to play a fireproof role, but the coating is thin, and it is easy to lose the protective function of the board due to scratches and damage. Under the condition of factor interference, it is difficult to extinguish automatically, so that the entire board will burn out and cause irreparable losses. Therefore, a flame-retardant wooden building board is proposed to solve the above problems
