摘　　要：针对水玻璃胶黏剂与木材黏结力低、耐水性差、脆性大等缺陷,通过硅烷偶联剂和氟硅酸钠对水玻璃胶黏剂进行改性以提升水玻璃与木材的黏结强度和耐水性。研究结果表明:少量硅烷偶联剂的加入可有效提升胶黏剂与木材的黏结强度,而氟硅酸钠对改善水玻璃胶黏剂的耐水性有积极作用,改性后的水玻璃胶黏剂能初步满足其在木材黏结中的应用需求。To address water glass low adhesive bond strength,poor water resistance and brittleness defects,a silane coupling agent and sodium fluorosilicate are used as modified additives for the water glass adhesive to enhance its adhesive strength and water resistance.The study indicates that adding a small amount of a silane coupling agent can effectively enhance the bond strength between the adhesives and wood,while sodium fluorosilicate can improve the adhesives＇ water resistance.Modified water glass adhesive can meet their basic requirements in wood bonding.
