摘要
Abstract
The UV-curable waterborne polyurethane was synthesized by using isophorone diisocyanate (IPDI),polytetrahydrofuran (PTMEG),dimethylol propionic acid (DMPA),and hydroxyl-terminated polystyrene (HTPS)as materials.The rigid phenyl group was introduced into the UV-curable waterborne polyurethane (UVWPU)structure to improve heat resistance and hardness of the coating film,and the product was confirmed using FT-IR.The effects of curing parameter,dosage of DMPA and HTPS on the properties of coating and emulsion stability were discussed.The results show that the storage stability of the emulsion is over 6 months when the amount of DMPA is above 6 %,and the coating film exhibits ex-cellent appearance and good properties when the curing parameter is above 1.35.The weight-loss tempera-ture of 5 % and 10 % is respectively 245 ℃ and 282 ℃,which is higher 32 ℃ and 27 ℃ than the UVWPU without using HTPS modified,and the adhesion and pencil hardness are also improved.关键词
