所述混合溶液A包括：环氧丙烯酸酯、丙烯酸丁酯、十二碳醇酯，其质量比为5:1:1:0.1；所述包合物B由β-环糊精与甲基丙烯酸缩水甘油酯反应制得，其质量比为1:2；所述混合液C包括：三氧化二锑、氢氧化镁、氢氧化铝、UV胶，其质量比为3:1:1：0.1。
改性粘胶纤维包括：按重量份计，粘胶纤维70-90份、阻燃剂溶液15-25份；阻燃剂溶液为质量比为1：2的β-环糊精和三聚氰胺磷酸酯混配溶液。
一种耐水洗阻燃无纺布的制备方法，包括以下4个步骤；
(1)制备阻燃剂溶液，步骤如下：
取β-环糊精，加入蒸馏水制成饱和溶液，加入AlCl3混合，温度为60-70℃条件下，搅拌30-40min,静置，抽滤，乙醇溶液水洗，烘干，制得包合物A(包覆Al3+的β-环糊精)；三聚氰胺磷酸酯溶液与包合物A混合，超声分散10-20min,制得阻燃剂溶液；
三聚氰胺磷酸酯溶液是一种氮-磷系协同阻燃剂，是目前纺织工艺中常用的高效阻燃剂，具有烟气毒性低、不含卤族元素、持久性好、阻燃效果良好的特点；但三聚氰胺磷酸酯溶液与无纺布界面的相容性不够理想，易吸潮导致电性能较差；阻燃性能未能充分发挥，阻燃效果不理想，易产生熔融物滴落的现象。本技术方案中利用β-环糊精将AlCl3引入到系统中，β-环糊精分子内腔空间大且疏水，避免了吸潮现象，β-环糊精具有增溶性，与无纺布基层相容性良好。AlCl3中Al3+与三聚氰胺磷酸酯上P＝O键协同作用；使三聚氰胺磷酸酯热稳定性增强，燃烧时催化粘胶纤维裂解产生更多的焦炭，在无纺布基层形成碳化覆盖层，阻止外部氧气进入和热量的散出，同时抑制可燃气体的产生；提高了无纺布的阻燃性。
(2)制备改性粘胶纤维，步骤如下：
向阻燃剂溶液中加入粘胶纤维纺丝原液；磁力搅拌30min，搅拌速度为180-220r/min，得到共混液；共混液在温度为27-32℃条件下，真空脱泡40-45min，得到改性粘胶纺丝液；
将改性粘胶纺丝液与凝固浴中的凝固剂接触，经纺丝孔输出形成初生纤维；对初生纤维牵伸；中和、水洗；得到改性粘胶纤维。
(3)制备无纺布基层，步骤如下：
S1.将改性粘胶纤维、涤纶纤维、丙纶纤维开松，混条；
S2.梳理除杂，堆叠铺成纤维网，纤维网层数为8-10层；
S3.将纤维网自上而下针刺巩固；依次经一道预针刺、三道主针刺、高温热轧、卷绕；其中预针刺的针频为600刺/min，针深为12mm；第一主针刺的针频为750刺/min，针深为10mm；第二主针刺的针频为750刺/min，针深为8mm；第三主针刺的针频为750刺/min，针深为5mm；高温热轧，热轧温度为220-225℃；进入卷曲机卷绕；制得针刺无纺布；
S4.将针刺无纺布以7-9m/min匀速通过上述制备的阻燃剂溶液，使针刺无纺布在阻燃剂溶液中充分浸润；经阻燃剂溶液浸润后的针刺无纺布，以7-9m/min的速度，依次通过双辊压轧、轧干力度3-6kg；拉幅；温度为145-150℃条件下烘干，并将表面烫平压光得无纺布基层。
丙纶纤维、涤纶纤维属于本质阻燃型纤维；改性粘胶纤维经阻燃剂溶液处理后具有阻燃性能；将三种纤维共混，针刺制成的无纺布再经阻燃剂溶液浸泡处理，使得无纺布具有良好的阻燃效果。
(4)制备耐水洗层、阻燃层，步骤如下：
S1.耐水洗层：环氧丙烯酸酯、丙烯酸丁酯、十二碳醇酯、以质量比5:1:0.1加入去离子水中，搅拌10-15min，制得混合液A；
将β-环糊精与甲基丙烯酸缩水甘油酯以质量比1：2的比例加入到二甲基乙酰胺溶剂中，加入对苯二酚，在温度为57-62℃条件下，反应6h；自然冷却；向其中加入丙酮溶液，反应产生白色成定；过滤白色沉淀，丙酮溶液洗涤；真空干燥，制得包合物B；
将无纺布基层放入混合液A中，浸泡40-60min；加入包合物B，包合物B与混合溶液A混合；在温度为37-40℃、在光引发的条件下，光引发剂选用自由基光引发剂1173(2-羟基-2-甲基-1-苯基丙酮)，浸泡6-8h；真空烘干，形成耐水洗层；
因环氧丙烯酸酯是一种优良的环氧树脂，具有优异的耐水性、耐热水性、耐药物性、粘结性、韧性，用其浸泡无纺布基层，可形成耐水性强的保护薄膜；但环氧丙烯酸酯极其粘稠，常温下无流动性，固加入丙烯酸丁酯作为活性稀释剂，稀释降低环氧丙烯酸酯的粘度，减小其薄膜的交联密度，进而降低环氧丙烯酸酯凝胶程度；使无纺布基层形成较优的环氧丙烯酸酯薄膜。将甲基丙烯酸缩水甘油酯引入到β-环糊精分子内，形成包合有乙烯基基团的β-环糊精超分子；β-环糊精超分子通过光引发剂，接枝到环氧丙烯酸酯、丙烯酸丁酯、十二碳醇酯的交联体系中，乙烯基与环氧丙烯酸酯共聚，增加薄膜的断裂伸长率，提高薄膜韧性；利于提高环氧丙烯酸酯薄膜的自我修复功能，在表层受到外力刮擦时，薄膜可完成自我修复，不产生裂纹。故环氧丙烯酸酯、丙烯酸丁酯、β-环糊精、甲基丙烯酸缩水甘油酯共同作用，可形成耐水洗层，同时耐水洗层还具良好的自我修复功能。
S2.三氧化二锑、氢氧化镁、氢氧化铝、UV胶混合熔融，制得混合液C；在S1中制备的无纺布基层正、反面涂覆涂混合液C，涂层厚度为15-30μm，静置，烘干，形成阻燃层。
三氧化二锑、氢氧化镁、氢氧化铝属于无机阻燃剂，在燃烧初期熔融，在无纺布基层表面形成致密保护膜来隔绝空气；分子内部吸热，可降低燃烧温度，起到阻燃作用；在高温时分子气化，降低空气中氧浓度，从而起到阻燃作用。
与现有技术相比，本发明的有益效果是：
利用三聚氰胺磷酸酯、β-环糊精、AlCl3复配阻燃剂，阻燃性对粘胶纤维进行改性处理，再对无纺布基层进行浸泡，得到阻燃无纺布。阻燃无纺布浸泡在环氧丙烯酸酯、丙烯酸丁酯、β-环糊精、甲基丙烯酸缩水甘油酯混合溶液中，经过系列反应，在无纺布基层形成了耐水洗且具有自我修复功能的耐水洗层。最后在无纺布最外层，涂覆三氧化二锑、氢氧化镁、氢氧化铝、UV胶混合熔融液，形成致密阻燃层。综上所述，本技术方案提供的耐水洗阻燃无纺布，具有良好的阻燃性和耐水洗性能。
