| 中文摘要: |
| 以玉米淀粉为原料,过硫酸铵( APS)与亚硫酸氢钠( NaHSO3 )为引发剂,丙烯酰胺( AM)与丙烯酸丁酯(BA)为接枝单体,环氧氯丙烷(ECH)为交联剂,制得了接枝交联双重改性淀粉基木材胶黏剂。 采用红外光谱对样品进行了表征,并研究了 AM 与 BA 质量比、APS 与 NaHSO3 质量比、反应温度、反应时间对淀粉基木材胶黏剂胶合强度及耐水性的影响。 实验结果表明,AM 与 BA 的接枝改性可以提高淀粉基木材胶黏剂胶合强度及耐水性,红外光谱证实 AM 和 BA 与淀粉发生了接枝反应。 |
| 英文摘要: |
| Using corn starch as raw material, ammonium persulfate (APS) and sodium bisulfite (NaHSO3 ) as initiator, acrylamide (AM) and butyl acrylate (BA) as grafting monomer, epichlorohydrin (ECH) as cross-linking agent, we prepared a grafting and cross-linking modified starch adhesive for wood application. Infrared spectrum was used for characterization of the sample and the influence of mass ratio of AM and BA, the mass ratio of APS and NaHSO3 , reactive temperature, and reaction time on bonding strength and water resistance of the starch based wood adhesive were investigated. The experimental results showed that AM and BA grafting modification greatly improves the bonding strength and water resistance of starch based wood adhesive; infrared spectrum confirms the grafting reaction among AM, BA, and starch. |
