摘要
以2-氟丙烯酸和聚氨酯为原料,反应过程中加入乳化剂(A-102),制得2-氟丙烯酸聚氨酯树脂产品,反应条件温和,产品收率高、性能更优越。进一步探讨了乳化剂(A-102)用量、反应温度及升温速度、原料加入方式等因素对产品性能的影响。结果表明:乳化剂(A-102)用量为0.3%(质量分数)、反应温度80～85℃、4～5℃/min程序升温、聚氨酯均分4批次和2-氟丙烯酸均分3批次加入反应时,2-氟丙烯酸聚氨酯产品收率最高达63%,树脂的Ca2+稳定性能、耐水性能最佳,断裂伸长率最高可达670%。
Abstract
Using 2-fluoroacrylic acid and polyurethane (PU) as raw materials and adding emulsifier (A-102) in the reaction process,2-fluoroacrylate polyurethane resin was successfully prepared.The effects of the amount of emulsifier (A-102),reaction temperature,heating rate and the way of adding raw materials on the properties of the product were discussed.The results showed that the amount of emulsifier (A-102) was 0.3wt%,the reaction temperature was 80～85℃,the temperature was 4～5℃/min,the polyurethane was added in 4 batches and the 2-fluoro-acrylic acid was added in 3 batches,the product yield was up to 63%.The Ca2+ stability and water resistance of the resin were the best,and the elongation at break was up to 670%.
