The processes such as the invention discloses the methods using fire-retardant composite urea formaldehyde resin production particieboard, including stock up, and dry, peeling desanding, sorting polishing, tune glue mixing are hot-forming.The key of production method of the present invention is to use cyanurotriamide modified urea resin for adhesive major ingredient, and addition oxidized starch is sticky complexing agent；Polyvinyl alcohol is toughener；Hydrogenated rosin is antioxidant；Polyisocyanate is curing agent；Isobutyl triethoxy silane is bridging agent；Phenolate lignin is formaldehyde catching agent and adds the fire-retardant composite urea formaldehyde resin that fire retardant is prepared again, which has residual formaldehyde amount low, the good advantage of flame retardant property, by the internal endothermic reaction, reduces ignition temperature；Residual formaldehyde amount is low in particieboard to make production obtain, in the case of fire, can be effectively fire-retardant. |
