Alfalfa meal manufacturing method utilizing biomass preparation Adhesive

The present invention relates to a method of manufacturing adhesive alfalfa meal prepared using biomass. Weigh alfalfa meal, after soaking in water, ethanol, stir, filtered off with suction; adjusting the pH of the filtrate, and the filtrate was heated, after incubation, was cooled to room temperature, filtered off with suction, the filter cake dried; cake weighed set filled with distilled water to a three necked flask, sodium dodecylbenzenesulfonate, after heated for a time, dropwise NaOH, adjusting the solution to pH 9, was added polyphenyl polymethylene polyisocyanates and reacted to produce biomass adhesive. The present invention in a wide range of planting, high yield, renewable alfalfa powder as a raw material, biomass prepared adhesive having good adhesion properties obtained with alfalfa processing products of industrial value, improved alfalfa harmful component value, at the same time, the resulting adhesive does not contain formaldehyde, aromatics, low cost, simple process, can be used in wood plywood, particleboard, fiberboard, and other fields.
