Abstract

The invention discloses an anti-corrosion and flame-retardant formaldehyde-free plywood, comprising a first rotary-cut veneer, a second rotary-cut veneer, a third rotary-cut veneer, and a flame-retardant aluminum foil layer, and the first rotary-cut veneer is located at the bottom , the second rotary veneer is fixedly connected to the first rotary veneer, the third rotary veneer is fixedly connected to the second rotary veneer, and the flame retardant aluminum foil layer is fixedly connected to the third rotary veneer; the The hot melt adhesive film is prepared from the following raw materials by weight: EVA elastomer, terpene resin, hydrogenated petroleum resin, microcrystalline wax or paraffin, dibutyl phthalate calcium carbonate, BHT, tert-butyl peroxide -2 Ethylhexyl carbonate, fumed silica, polyvinyl alcohol, flake alkali, ammonium chloride, ethylene urea, ethanolamine, boric acid. The invention also discloses a preparation method of anti-corrosion and flame-retardant formaldehyde-free plywood. The anti-corrosion and flame-retardant formaldehyde-free plywood prepared by the invention has higher mechanical strength, flame-retardant performance and anti-corrosion performance.

Description

technical field [0001] The invention belongs to the technical field of wood preparation, and in particular relates to an anti-corrosion and flame-retardant formaldehyde-free plywood and a preparation method thereof. Background technique [0002] Plywood is a three-layer or multi-layer board material made of wood segments that are cut into veneers or sliced ​​into veneers, and then glued together with adhesives, usually with odd layers of veneers, and adjacent layers of veneers The fiber directions are glued perpendicular to each other. [0003] Plywood is one of the commonly used materials for furniture. It is one of the three major wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneer is usually formed by gluing the wood grain directions of adjacent layers perpendicular to each other. Usually, the surface plate and the inner layer are symmetrically arranged on both sides of the center layer or the ...
