乳化剂十二烷基硫酸钠(SDS)对淀粉基木材胶特性的影响
Effects of SDS on the Performance of Starch-based Wood Adhesive
摘要
Abstract
The effects of emulsifiers(SDS) on storage stability in low temperature and bond strength of starch-based wood adhesive were investigated.Compared to starch-based wood adhesive without emulsifiers,emulsifier-fortified starch-based wood adhesive all exhibited enhanced glue strength.The optimum amount of SDS is 1% of starch content.In particular,SDS has the most significant effect that dry strength of starch-based wood adhesive was increased by 60.1% and the wet strength was increased by 211.5%,respectively.The grafted parameters were also remarkably increased by adding SDS,for instance G increased by 93.7% and GE increased by 83.8%.It was proved by the stability test of low temperature resistance that emulsifiers can increase the numbers of cooling-thawing circulation.Starch-based wood adhesive with SDS has the best effect from five circulations.The results of dynamic time sweep experiments and TEM showed that SDS could weaken hydrogen's bonding strength of the starch molecules,and significantly enhance the parameters of grafted reaction,thereby finally improve the bonding properties and stability of starch-based wood adhesive emulsion.关键词
