Abstract

The invention discloses fireproof plywood. The fireproof plywood comprises a first fireproof plate and a second fireproof plate which are arranged symmetrically. A sound insulation plate and a connecting plate are sequentially arranged between the first fireproof plate and the second fireproof plate, and the first fireproof plate, the sound insulation plate, the connecting plate and the second fireproof plate are fixedly connected through adhesives; the first fireproof plate and the second fireproof plate are internally provided with a first cavity and a second cavity correspondingly, and through openings communicating with the first cavity and the second cavity correspondingly are formed in the side walls of the upper sides of the first fireproof plate and the second fireproof plate correspondingly; and water leakage openings communicating with the first cavity and the second cavity correspondingly are formed in the side walls of the sides, opposite to each other, of the first fireproof plate and the second fireproof plate correspondingly. The fireproof plywood is easy to operate and convenient to use; when heated, expansion pipes expands to open sealing plates in a jacking mode,thus water leaks out from the water leakage openings to extinguish flame, and the fireproof effect is good; and sound insulation is effectively achieved through the sound insulation plate.

Description

technical field [0001] The invention relates to the technical field of plywood, in particular to a fireproof plywood. Background technique [0002] Plywood is one of the commonly used materials for furniture. It is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers are usually perpendicular to each other according to the grain direction of adjacent layers. The billets are glued together, usually the surface board and the inner board are symmetrically arranged on both sides of the center layer or the board core, and the slabs made of veneers after gluing are criss-crossed according to the direction of the wood grain. Pressed under heated conditions. General plywood has poor fireproof performance, low safety performance, and poor sound insulation effect; therefore, we propose a fireproof plywood to solve the above problems. Contents of the invention [0003] The...
