摘要:
本发明涉及保温材料技术领域,尤其是一种瓦楞纸板用PVA粘合剂,所述粘合剂由下列质量份组成:玉米淀粉粘合剂10~20份,聚乙烯醇2.5~6份,氧化剂0.04~0.06份,消泡剂0.03~0.05份,防腐剂0.01~0.03份,30%氢氧化钠溶液0.5~1.5份,2%氢氧化钠溶液0.1~0.5份,水40~90份,纤维素醚2~4份。本发明公开的一种瓦楞纸板用PVA粘合剂,提高了现有粘合剂的粘合强度,进而增强了瓦楞纸板的抗压能力。
摘要(英):
The invention relates to the technical field of thermal insulation materials, and in particular to a PVA (polyvinyl alcohol) adhesive for corrugated boards. The PVA adhesive comprises, by mass, 10-20parts of maize starch adhesive, 2.5-6 parts of polyvinyl alcohol, 0.04-0.06 parts of oxidant, 0.03-0.05 parts of defoaming agent, 0.01-0.03 parts of preservative, 0.5-1.5 parts of 30% of sodium hydroxide solution, 0.1-0.5 parts of 2% of sodium hydroxide solution, 40-90 parts of water and 2-4 parts of cellulose ether. The PVA adhesive for the corrugated boards has the advantages that adhesive strength of existing adhesives is improved, and anti-pressure ability of the corrugated boards is enhanced.
