Abstract

The invention is aldehyde-free environment-friendly flame-retardant plywood and a preparation method thereof, belonging to the processing and preparation field of plywood, in particular to environment-friendly flame-retardant plywood without the release of harmful gases, such as formaldehyde, and the preparation method thereof. The invention is characterized in that the plywood is processed and prepared by a soy-based flame-retardant antistatic biological macromolecular adhesive, wherein the adhesive comprises the following components (part by weight): 40-70 parts of soy-based lumber adhesive (solid content: 25% plus or minus 5), 5-20 parts of crosslinker, 2-10 parts of flame-retardant, 0.5-3 parts of antistatic agent, 0.5-3 parts of mothproof and mildewproof auxiliary agent and 20-40 parts of flour. The invention provides an aldehyde-free environment-friendly flame-retardant plywood which releases no harmful gases, such as formaldehyde and has excellent flame-retardant effect, high strength, good surface decoration and antistatic performance, and a preparation method thereof, thus solving the problems that the harmful gases such as formaldehyde released by the plywood products pollute the environment and the plywood products have low flame-retardant level.

Description

technical field [0001] The invention relates to a formaldehyde-free and environment-friendly flame-retardant plywood and a manufacturing method thereof. The invention belongs to the processing and manufacture of plywood, and in particular relates to an environment-friendly flame-retardant plywood without formaldehyde and other harmful gas release and a manufacturing method thereof. Background technique [0002] Wood plywood products are widely used in indoor and outdoor decoration, furniture manufacturing and vehicle and ship processing industries of fixed buildings such as homes, offices, halls, theaters, shopping malls, hotels, airports, stations, etc. The release of free formaldehyde from plywood pollutes the environment and affects human health. The flame retardant properties of plywood are closely related to the fire safety of human living and working environments. [0003] In the prior art, formaldehyde-free plywood only does not use the so-called three-aldehyde resi...
