摘要
研究了六羟树脂改性对淀粉胶粘剂性能的影响。结果表明,六羟树脂与淀粉在催化剂存在的条件下发生了醚化反应,最佳改性条件为:六羟树脂添加量7mL/100g淀粉胶,催化剂(柠檬酸)添加量0.3g/100g淀粉胶,反应温度65℃,反应时间1h。将最佳改性条件下制备的淀粉胶粘剂用于刨花板的压制,结果表明,六羟树脂改性在保证淀粉胶流动性的情况下,提高了所制刨花板的内结合强度和耐水性。
In this paper,the capabilities of starch-based adhesive modified by hexamethoxy-methylmelamine were studied.The result showed that a etherization reaction was occurred between hexamethoxy-methylmelamine and starch.The optimum dosage of hexamethoxy- methylmelamine and catalyzer were 7mL and 0.3g for 100g adhesive,and the optimum reacting temperature and reacting time were 65℃ and l h respectively.Particleboards prepared with an optimal adhesive formulation exhibited good water resistance and internal bond strength while the fluidity of the starch-based adhesive remained in a good level.
