一种环保瓦楞纸板粘合剂及其制备方法
摘要：
本发明公开了一种环保瓦楞纸板粘合剂及其制备方法，涉及粘合剂技术领域。本发明瓦楞纸板粘合剂包括以下重量份的原料：玉米淀粉80～100份、轻质填充料10～20份、改性凹凸棒土6～12份、磺酸化三聚氰胺2～5份、烧碱10～16份、聚乙烯醇树脂5～10份、聚四氢呋喃醚二醇2～6份、抗氧剂BHT0.5～2份、水650～700份；制备方法包括混合浆液的制备、粘合剂混料、分散出料。本发明的粘合剂粘度高、水溶性好，提高了粘合后瓦楞纸板的抗压强度和戳穿强度等力学性能。
摘要（英）：

The invention discloses an environment-friendly corrugated paperboard adhesive and a preparation method thereof, and relates to the technical field of adhesives. The corrugated paperboard adhesive comprises, by weight, 80-100 parts of corn starch, 10-20 parts of light fillers, 6-12 parts of modified attapulgite, 2-5 parts of sulfated melamine, 10-16 parts of caustic soda, 5-10 parts of polyvinyl alcohol resin, 2-6 parts of polytetrahydrofuran ether glycol, 0.5-2 parts of antioxidants BHT and 650-700 parts of water. The preparation method includes the steps of mixed slurry preparation, adhesivemixing and scattered discharging. The adhesive is high in viscosity and good in water solubility, and mechanical properties such as the compressive strength and puncture strength of an adhered corrugated paperboard are improved.
