单宁-苯酚-甲醛树脂胶接性能
|
摘要
以杨梅单宁和相思单宁取代酚醛树脂中的部分苯酚合成单宁-苯酚-甲醛树脂,研究酚醛树脂摩尔比、单宁种类及单宁取代率对酚醛树脂刨花板内结合强度的影响。结果表明,酚醛树脂摩尔比和单宁自身的结构对改性酚醛树脂刨花板内结合强度有较大影响:在低摩尔比(1.3∶1)时,杨梅单宁和相思单宁的引入会降低改性后的酚醛树脂刨花板内结合强度;在高摩尔比(1.8∶1)时,杨梅单宁和相思单宁改性的酚醛树脂刨花板内结合强度均得到提高,两者苯酚最大替代率分别为30%和50%,内结合强度提高幅度分别为13%和54%。
Bayberry tannin and acacia tannin were as the substitutes to prepare tannin-phenol-formaldehyde resin of particleboard and the internal bond strength of particleboard influence by mole ratio,tannin types and tannin substitution rate was analysised. The results indicated that tannin structures and mole ratio had a great effect on bonding performance of modified phenol formaldehyde resin. At low mole ratio( 1. 3 ∶ 1),phenol formaldehyde resin modified with bayberry tannin and acacia tannin had badly bonding performance. But,the results were the opposite when phenol formaldehyde resin modified with bayberry tannins and acacia tannin at high mole ratio( 1.8 ∶ 1). The maximum rates of bayberry tannin and acacia tannin substitution rate of phenol were 30% and 50%,and the internal bond strength of particleboard increased by 13% and 54%.
