摘要
采用蓖麻油为内交联剂合成防水性能较好的聚氨酯成膜剂,以表面能、吸水率、接触角等指标分别考察蓖麻油的不同用量对聚氨酯防水性的影响。结果表明:当蓖麻油最佳用量为4%时,制得的水性聚氨酯膜有良好的防水性能和一定的力学性能。
The aqueous polyurethane film forming agent was achieved via internal crosslinked by castor oil, and the waterproofness influenced by various dosages of castor oil was researched by applying several detection methods including surface energy, absorption ratio, contact angle, etc. The results revealed that the corresponding aqueous polyurethane film forming agent exhibiting good waterproofness and mechanical properties when the dosage of castor oil reached 4%.
