▎ 摘  要

NOVELTY - Adhesive comprises 20-30 wt.% corn starch, 6-8 wt.% alpha -amylase, 0.08-0.14 wt.% graphene oxide, 0.5-1 wt.% dispersant, 6-8 wt.% guar gum, 6.5-8.8 wt.% change Basalt fiber, 0.8-1. 6 wt.% pyrethroid insecticide, 5-6.8 wt.% cyclodextrin, and balance is water. The modified basalt fiber is a basalt fiber subjected to surface graft modification treatment by a silane coupling agent. The cyclic dextrin is one of -cyclodextrin and gamma -cyclodextrin. USE - Adhesive for bamboo products. ADVANTAGE - The adhesive has more efficient and longer-lasting anti-insect and anti-mite effect, and has stronger compression shear strength, immersion peeling performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a adhesive, which involves: (A) adjusting corn starch to a concentration of 35-45% aqueous solution, adding alpha -amylase at a temperature of 60-70 degrees C, 20-40 Mega pascals (Mpa) homogenization for 40-50 minutes to obtain a mixture A; (B) dissolving another pyrethroid insecticide in dichloromethane to form an organic phase, adding cyclodextrin with water to form an aqueous phase, mixing organic phase and the aqueous phase and adding emulsifier, homogenization at room temperature for 25-30 minutes under a pressure of 20-40 MPa to obtain a mixture B; (C) adjusting pH of the mixture A is 7.0-7.2, adding graphene oxide, a dispersant, a modified basalt fiber, a mixture B, and stirring for 30-35 minutes to obtain a mixture C; and (D) adding guar gum to the mixture C, stirring for 1-1.5 hours to obtain finished product.
