Glued board is one of furniture common used material, is a kind of wood-based plate.It is mutual that one group of veneer usually presses adjacent layer grain direction
Perpendicular assembly gluing forms, its usual dash board and inner plating are symmetrically arranged at the two sides of central core or plate core.After gluing
The slab that is made into a crisscross manner by grain direction of veneer, suppressed under conditions of being heated or not heated.The number of plies is generally
Odd number, minority also have even number.The physics in direction, engineering properties difference are smaller in length and breadth.There are commonly three-ply board, five-ply boards etc..Glue
Plywood can improve timber utilization rate, be a main path for saving timber.Glued board is frequently with the adhesive glue containing formaldehyde
It closing, the formaldehyde in glued board can play the role of certain anticorrosive mildewproof, as one of material the most commonly used in modern house ornamentation,
Glued board has many advantages, such as that beauty is economical, still, since glued board can continue the release formaldehyde into air, also becomes finishing and is made
At one of the primary pollution source of air pollution.Formaldehyde is a kind of colourless readily soluble irritative gas, the Form aldehyde release of glued board
Phase is up to 3~15 years, can absorb through respiratory tract, and formaldehyde has chronicity, latency, concealed feature to the harm of human body, long
Phase inhaled formaldehyde can cause the serious diseases such as nasopharyngeal carcinoma, larynx cancer.A large amount of startling facts confirm, by nuisances such as formaldehyde
Room air pollution caused by matter has become " the stealthy killer " for endangering human health, also becomes what whole world various countries were paid close attention to jointly
Problem.
Summary of the invention
It is an object of the invention to overcome the shortage of prior art, a kind of anticorrosive mildewproof environment-friendly plywood and its preparation side are provided
Method.The glued board sticks agent gluing using modified urea-formaldehyde resin glue, and burst size of methanal is low, and anticorrosive mildewproof, superior performance.
To achieve the goals above, technical solution provided by the invention is as follows:
A kind of anticorrosive mildewproof environment-friendly plywood, is formed by Wooden veneer gluing；The adjacent Wooden veneer timber presses line
It is glued to manage mutually perpendicular direction；Agent gluing, the modified urea-formaldehyde are sticked using modified urea-formaldehyde resin glue between the Wooden veneer
