摘要：以漆酚(URU)为原料,与没食子酸(GA)发生催化交联反应得到新型双组分漆酚/没食子酸聚合物(UG),利用红外、核磁等表征手段对其结构进行表征,并初步提出两者共聚反应的机理为自由基共聚反应。进一步将聚合物UG与聚合桐油、漆蜡等经高速共混,得到均匀分散的混合多组分涂膜液。研究了聚合桐油、漆蜡的添加量对多组分涂膜物理机械性能、热重以及疏水性能涂膜的影响。结果表明,当聚合桐油和UG质量比为4∶6时,所制得涂膜的物理机械性能最佳。经5%Na Cl、5%H2SO4、5%Na OH作用48 h,涂膜未出现变色、起皱或龟裂。
A novel urushiol/gallic acid polymer(UG)is prepared by catalytic reaction between urushiol and gallic acid.UG’s structure is characterized by means of IR and H NMR.The mechanism of polymerization between urushiol and gallic acid is proposed to be a free-radical copolymerization.An evenly dispersed multicomponent coating film solution is obtained through blending UG,polymerized tung oil and lacquer wax together by high speed stirring.The effects of the ratio of polymerized tung oil to UG and lacquer wax content on the performance of multicomponent coating film are studied via physical and mechanical property tests,TG analysis and hydrophobic properties test.It is found that the film will exhibit the best comprehensive performance when the ratio of polymerized tung oil to UG is 4∶6.After the film has been soaked in 5%NaCl,5%H2SO4,and 5%Na OH,respectively for 48 h,it does not appear blister,cracking spot or spoiled.
