Description

Reinforced flame-retardant damp-proof plywood

Technical Field

The utility model belongs to the technical field of the timber sheet material, especially, relate to a fire-retardant dampproofing plywood of strenghthened type.

Background

The plywood is one of three kinds of artificial boards, and is three-layer or multi-layer board material formed by rotary cutting wood into single boards or slicing wood into thin wood and gluing with adhesive. A group of veneers are typically assembled and glued perpendicular to each other in the direction of the adjacent layers of wood grain, and the skins and inner sheets are typically symmetrically disposed on either side of the center layer or core. The glued veneer is pressed into the wood grain board blank by the criss-cross matching of the glued veneer according to the wood grain direction under the condition of heating or not heating. The plywood can improve the utilization rate of the wood and is a main way for saving the wood. The application fields of the plywood comprise furniture, airplanes, ships, trains, automobiles, buildings, packing cases and the like.

With the improvement of living standard, many places have higher requirements on flame retardance and space humidity, and the traditional flame-retardant damp-proof plate is lower in strength and easy to damage.

SUMMERY OF THE UTILITY MODEL

In order to overcome many places and have higher requirement to fire-retardant and space humidity, traditional fire-retardant dampproofing sheet material intensity is lower, fragile scheduling problem, the utility model provides a fire-retardant dampproofing plywood of strenghthened type adopts following technical scheme:

the utility model provides a fire-retardant dampproofing plywood of strenghthened type, includes the core, and the symmetry has set gradually guard plate, gusset plate and table board above the core and bottom surface, and the core includes grid plate and the strengthening rib that sets up from top to bottom, and the strengthening rib is located between two upper and lower grid plates, it has the fire-retardant compounding of dampproofing to fill between two upper and lower grid plates, and the guard plate is glass magnesium board, has evenly seted up a plurality of round holes on the gusset plate, and what between core, guard plate, gusset plate and the table board is through melamine glue veneer.

Furthermore, the surface plates on the upper surface and the lower surface are made of birch plates.

Furthermore, the surface of the surface plate on the upper surface and the surface of the surface plate on the lower surface are coated with EVA composite waterproof layers.

Furthermore, the moisture-proof flame-retardant mixed material is formed by mixing absorbent cotton, activated carbon, desiccant particles, gypsum, asbestos powder and fireproof cotton.

Furthermore, the reinforcing ribs are stainless steel metal tubes.

Has the advantages that: the utility model discloses an above adopting the core and the bottom surface symmetry in proper order have set up the guard plate, the structural scheme of gusset plate and dash board, the dash board surface on upper and lower two sides all scribbles EVA composite waterproof layer, can effectively play waterproof effect, it has dampproofing fire-retardant compounding to fill between two grid plates about in the core, can adsorb the humid gas in the air, can play certain flame retardant efficiency simultaneously, the inside strengthening rib that is equipped with of core, can improve the bulk strength of sheet material, glass magnesium board has higher waterproof, fire behavior, still be equipped with the gusset plate between guard plate and dash board, liquid glue can enter into the round hole of gusset plate, can increase the adsorption efficiency of glue, also promote holistic intensity, the utility model discloses compare traditional plywood, when having fire-retardant damp-proof function, can have higher intensity.
