Abstract

The invention discloses flame-retardant composite urea resin and a production method thereof; the flame-retardant composite urea resin is prepared from melamine-modified urea resin, oxidized starch, polyvinyl chloride, hydrogenated rosin, propanediol polyoxypropylene polyvinyl ether, polyisocyanate, isobutyltriethoxysilane, phenolated lignin, clear water, and a flame retardant; the production method comprises: placing clear water in a reactor, heating to 80-100 DEG C, adding hydrogenated rosin, isobutyltriethoxysilane and propanediol polyoxypropylene polyvinyl ether, stirring for 10-30 min, adding polyvinyl chloride and phenolated lignin and dissolving them, adding certain parts by weight of melamine-modified urea resin, oxidized starch and flame retardant, holding the temperature of 80-90 DEG C, stirring and reacting for 2-5 h, adding polyisocyanate 10-20 min before usage, and mixing and stirring well. The flame-retardant composite urea resin is good in flame retardance, acts as a main adhesive for artificial boards and can provide improved flame retardance for artificial boards.

Description

technical field [0001] The invention belongs to the field of adhesive production, in particular to a flame-retardant composite urea-formaldehyde resin and a production method thereof. Background technique [0002] With the development of China's economy and the improvement of people's living standards, the requirements for home decoration are also constantly increasing. Because of its natural and beautiful texture and good texture, wooden floor has become the first choice material for home floor decoration. Solid wood composite flooring overcomes the shortcomings of solid wood flooring wet expansion and shrinkage, has good dimensional stability, and at the same time retains the natural wood grain and comfortable foot feel of solid wood flooring, thus becoming an important variety in flooring. The production of solid wood composite flooring The amount of urea-formaldehyde resin floor glue used has also increased. Urea-formaldehyde resin or modified urea-formaldehyde resin a...
