摘要
在空气和N2气氛下对马来酸酐接枝聚丙烯(PP-g-MAH)乳液进行了差热-热重分析,以考察其耐热稳定性;同时测试了不同固含量的乳液涂膜在不同温度下的成膜所需时间,及其对水的接触角、硬度以及涂层的附着力.结果表明,PP-g-MAH乳液在200℃以内具有很好的耐热稳定性;乳胶膜的接触角和硬度均随着成膜温度的升高而呈现先增大后减小的趋势,且在成膜温度为165℃时具有最佳的综合性能.
DTA-TG analysis of PP-g-MAH emulsion in air and N2 was conducted in order to investigate its heat stability. The film formation time of different solid content PP-g-MAH emulsion film at different tem- perature and the contact angle to water, the hardness and coating adhesion of they were tested. The results showed that PP-g-MAH emulsion presented very good heat stability within 200 ℃. The contact angle and hardness of the film presented the trend of increasing firstly and then decreasing with the rise of tempera- ture. And the latex film achieved the best comprehensive performance at the temperature of 165 ℃.
