Description

阻燃、耐磨耗、仿真皮感的合成革浆料的制备方法
技术领域
本发明涉及到一种合成革的制备方法，尤其是一种阻燃、耐磨耗、仿真皮感的合成革浆料的制备方法。
背景技术
聚氨酯合成革具有光泽柔和、自然，手感柔软，真皮感强，耐扰曲，抗老化等优异的特点，是天然皮革的最为理想的替代品，广泛用于服装，制鞋，箱包，家具等行业，但是目前市场上的聚氨酯合成革在透湿性，耐磨性能方面与天然皮革差距太大，透湿性能差的聚氨酯合成革制品会令人感觉闷热、湿冷，针对这些缺点，目前主要通过改变聚氨酯合成革浆料的性能进行改善，但目前市场上改变聚氨酯合成革浆料透湿性和耐磨性的工艺较复杂，成本较高，效果不明显。
传统聚氨酯合成中使用二月桂酸二丁基锡，但由于在合成过程中，难以将其取出，造成不必要的安全隐患，因此需要寻找合适的催化剂。
传统的阻燃聚氨酯的阻燃性经常用施加阻燃剂的方式，而阻燃剂分为添加型和反应型两种，添加型用量大，效率高，反应型的阻燃剂相对较少，如”201410470376.9一种无卤阻燃热塑性聚氨酯”将热塑性聚氨酯90克原料在80℃鼓风干燥2h，然后将10克的5-(4-羟基苯基)-2H-吡喃-2-酮在90℃下干燥3小时，混合在一起，并加入7克的1098、5克的EBS、2克的A3800和0 .3克的二甲基硅油，在高速混合机SHR-50A中在1500rpm的转速下高速搅拌5分钟，停止搅拌，转移到双螺杆挤出机TSAE-35A中，进行熔融共混，挤出机1-4段温度分别是140、150、160、165℃，挤出物切粒后80℃干燥4h备用。因此需要找到适合的提高阻燃效率的材料。
据统计,全世界每年产生的鸡毛等禽类羽毛废弃物达500万吨左右。这些废弃羽毛只有少量被制成枕芯、被垫、羽毛扇、羽毛球等,大部分被当作垃圾直接丢弃,不但造成环境污染,还会给人体健康造成危害。而且,废弃羽毛的主要成分为角蛋白,在土壤中不易自行降解,不能直接作为有机肥料使用。而如果能利用角蛋白对聚氨酯改性，提高聚氨酯的真皮感，是一种好的办法。
发明内容
传统的聚氨酯合成革浆料所成膜存在着耐磨性、阻燃性差，而且涂饰在合成革上，降低了合成革的真皮感，本发明采用4-氨基-5-羟基-2,7-萘二磺酸为扩链剂，以甘露醇提高扩链效果，以N-羟甲基丙烯酰胺为聚氨酯预聚体中引入双键，在自制的引发剂条件下与四氟乙烯、偏二氟乙烯反应，来提高聚氨酯合成革的耐磨性，采用三氟甲基苯胺、对硝基苄醇丙二酸单酯镁、四丁基溴化铵、四乙基溴化铵为催化剂，取代传统的二月桂酸二丁基锡，降低重金属的毒性，同时筛选成炭促进剂，提高聚氨酯的阻燃性，而自制鸡毛水解液，加入到聚氨酯合成革浆料中，提高聚氨酯的真皮革。
阻燃、耐磨耗、仿真皮感的合成革浆料的的制备方法，其特征在于：
（1）阻燃性热塑性聚氨酯制备：在装有搅拌浆、温度计、冷凝管 500ml 的四口烧瓶中，将聚四氢呋喃醚二醇 80g 与二苯基甲烷二异氰酸酯 45g 混合，在催化剂0.12g 存在的条件下，于85℃下反应 2h，聚氨酯预聚体；向聚氨酯预聚体中加入4-氨基-5-羟基-2,7-萘二磺酸3.5g、甘露醇3.5g和N-羟甲基丙烯酰胺3.2g，于85℃反应 3h，加入成炭促进剂2.4g，于70℃反应 1h，加入三乙胺 9g 进行中和反应 60min，在高速搅拌下加入去离子水100g进行乳化分散，并向体系中加入四氟乙烯3.1g、偏二氟乙烯1.6g和二乙酸碘苯1.5g，在80℃下同时滴加质量分数10%的引发剂水溶液5.3g、鸡毛水解液6.6g和六甲基环三硅氧烷2.3g，滴加时间1h，滴加完保温反应2h，反应结束，调节pH到7.5，，得到阻燃性热塑性聚氨酯。
（2）将阻燃性聚氨酯树脂60份、丁酮25份、HDI三聚体固化剂9g、异辛酸铋促进剂6g按比例搅拌均匀配成无色高透明浆料。
其催化剂为对三氟甲基苯胺、对硝基苄醇丙二酸单酯镁、四丁基溴化铵、四乙基溴化铵、异丙基三(焦磷酸二辛酯)钛酸酯、1,4-双(二苯基膦)丁烷、马来酸二苄酯、丙二酸二苄酯中的任意一种。
