Abstract

The invention provides a composite wooden box adhesive and a preparation method thereof. The preparation method includes the steps: mixing phosphate ester starch and distilled water; heating mixture to reach the temperature of 60-70 DEG C; stirring the heated mixture for 10-30 minutes; adding chitosan, furcellaran, konjac glucomannan and hydrogen peroxide, and continuing to stir mixture for 30-50minutes; mixing polyvinyl alcohol, potassium peroxodisulfate and distilled water, and stirring mixture for 20-30 minutes at the temperature of 90-95 DEG C at the rotating speed of 200-300r / min; cooling the mixture to indoor temperature, and mixing two groups of components; adding corn prolamin, diacetyl tartaric acid mono-and diglycerides, N-dodecenyl succinic anhydride, Na-montmorillonite, citricacid and n-butyl alcohol; heating mixture to reach the temperature of 70-80 DEG C; stirring the mixture for 20-30 minutes; cooling the mixture to reach indoor temperature; performing ultrasonic cutting for 10-20 minutes, and standing and defoaming to obtain the composite wooden box adhesive. The composite wooden box adhesive has high adhesiveness and is rapid in curing and short in curing time.

Description

technical field [0001] The invention relates to the field of chemical adhesives, in particular to a composite wooden box adhesive and a preparation method thereof. Background technique [0002] Wooden box adhesive refers to the adhesive used for wood bonding and wood product manufacturing. It has the advantages of uniform stress, joint bridging, high bonding strength, and good water resistance. It can simplify the product structure and realize operation mechanization and automation. , mainly hide glue, bone glue, casein glue, polyvinyl acetate adhesive, phenolic resin adhesive, urea-formaldehyde resin adhesive, epoxy resin adhesive and neoprene adhesive. Generally, the adhesives on the market have certain disadvantages, such as low viscosity, long curing time, poor water resistance and non-wear resistance. Therefore, the research and development of wooden box adhesives with high viscosity and fast curing speed has important significance and broad market prospects for the de...
