The invention discloses a hot-pressed
veneer adhesive and a preparation method thereof. The hot-pressed
veneer adhesive mainly comprises the following components: deionized water,
polyvinyl alcohol, an emulsifier, an initiator,
methacrylic acid, N-methylol
acrylamide,
vinyl acetate, a
plasticizer, a
buffering agent, cassava
starch,
borax, a dispersing agent, aqueous
rosin, a defoaming agent and a
corrosion inhibitor. When the hot-pressed
veneer adhesive is prepared, the preparation method comprises the following steps of: firstly synthesizing a self-crosslinked
polyvinyl acetate copolymerization modified
emulsion, then adding 20-35% of raw cassava
starch, a crosslinking agent, waterborne tackifying resin and other auxiliaries for mixing and finally preparing the hot-pressed veneer adhesive with excellent performances. Compared with a traditional
urea resin veneer adhesive, the adhesive prepared by the invention has the advantages of convenience in use, low curing temperature, short
curing time and no harm to an environment and a
human body.
