SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fire-resistant environment-friendly plywood, if solve in case the conflagration breaks out, but the plywood is not just can not fire-retardant and still combustion-supporting, will cause the problem of huge loss for people's the lives and property.
The utility model adopts the following technical scheme:
the utility model provides a fire-resistant environment-friendly plywood, includes plywood body, bamboo fiberboard and flame retardant coating, the upper surface of plywood body is equipped with the flame retardant coating, the flame retardant coating is kept away from the surface connection of plywood body has the bamboo fiberboard, the plywood body includes rubberizing board, core and lower plywood, the lower surface of rubberizing board with the core upper surface bonds, the core lower surface with the plywood upper surface bonds down, the inside through-hole that is equipped with a plurality of parallel of core, the through-hole intussuseption is filled with fire-retardant fire extinguishing agent.
Furthermore, the flame retardant coating includes glass fiber layer and vermiculite layer, the vermiculite layer covers in glass fiber layer top, can make the plywood have stronger fire resistance, can strengthen the mechanical properties of plywood again.
Further, the diameter of the through hole is half of the height of the core plate, so that the mechanical performance of the core plate is less influenced by the through hole.
Furthermore, the flame-retardant fire extinguishing agent is a dry powder fire extinguishing agent, so that the fire extinguishing agent is easily filled into the through holes, and the performance of the plywood is not influenced.
Further, the lower surface of plywood body still is equipped with the PET waterproof layer, prevents that steam from getting into the plywood body, and plywood life shortens to rotten plywood body.
The utility model has the advantages that: this fire-resistant environment-friendly plywood passes through the fine and close flame retardant coating of glass fiber layer and vermiculite layer formation, form double protective layer structure, improve its fire resistance, and this intussuseption of plywood is filled with fire-retardant fire extinguishing agent further the fire prevention fire resistance of the plywood of having strengthened, it is equipped with harmful substance such as formaldehyde in the bamboo fiber board layer not only dampproofing antibacterial but also the absorption space to go up the top surface, more environmental protection, the bottom surface is equipped with the PET waterproof layer down and makes the plywood rot in the steam in the ground can not permeate into the plywood, plywood life has been prolonged.
Drawings
Fig. 1 is a schematic structural view of the present invention;
