摘　　要：文章以自制反应型硅油和丙烯酸酯类防水单体为原料,通过乳液聚合制备了新型有机硅改性聚丙烯酸酯类无氟防水剂,并研究了其在化纤面料上的整理工艺。优化的工艺条件为:该新型无氟防水剂在涤纶春亚纺、涤塔夫、尼丝纺、锦纶塔丝隆面料上的用量分别为20~30、40~60、40~50、30~50 g/L;焙烘温度为170℃,焙烘时间为60 s;其与交联剂搭配使用,选定的涤塔夫、尼丝纺面料在水洗30次后,室温晾干防水性能均可达80分,防水性能及耐洗性能优于市场畅销的无氟防水剂A、无氟防水剂B,且面料色变小,手感好;该新型无氟防水剂适用于大批量面料的防水加工,是无氟防水剂中综合性能突出的新一代产品。In this paper,a new fluorine-free waterproof agent of silicone modified polyacrylate was prepared by emulsion polymerization of self-made special reactive silicone oil and acrylate waterproof monomer,and its finishing process on chemical fiber fabrics was studied.The results showed that the optimized process of the new fluorine-free waterproof agent on different fabrics was as follows:poly pongee 20-30 g/L,polyester taffeta 40-60 g/L,nylon taffeta 40-50 g/L,and polyamide taslan 30-50 g/L under 170℃baking temperature for 60 seconds.After treatment with crosslinking agents and 30 washes,the waterproof rating still exceeds 80 points when air-dried indoors.The waterproof effect and washing resistance on polyester taffeta and nylon taffeta are better than the best-selling waterproof agents A and B in the market,with a soft hand feel and excellent long-lasting washing resistance.This new fluorine-free waterproofing agent is perfect for the waterproofing finishing of large quantities of fabrics,thanks to its exceptional overall performance.
