Description
技术领域
本发明涉及手套制备技术领域,特别是涉及一种耐强酸强碱防护手套的制备方法。
背景技术
防化手套也叫化学防护手套,通常采用DMF作为溶剂,是用来防护化学物质的产品,运用较多的PVC手套、乳胶手套、橡胶手套中的部分产品属于防化手套,除此之外,防化手套还有各种不同材质的品类,根据防化手套的材质有以下分类:
1.氯丁橡胶防化手套:氯丁橡胶的防酸、酒精、油、溶剂、酯、油脂和动物油的性能非常好,也能抗撕裂、刺穿、磨损和切割,且不含乳胶蛋白。制成的氯丁手套防化、抗老化性能出色,因此应用领域较广。
2.丁腈橡胶手套:丁腈橡胶手套的防酸碱、耐油性能非常好,对碳氢化合物的衍生物耐受性也很强。手套的防撕裂、刺穿、磨损和切割的性能要比氯丁橡胶和聚乙烯好,且不含乳胶蛋白,不会引起不良反应。
3.聚氯乙烯(PVC)防化手套:能够防护大多数油脂、油、酸、腐蚀物和石油碳氢化合物,也能防酒精和乙二醇醚酯,但抗机械性损伤强度弱,须避免接触乙醛、含有酮溶剂和芳香族溶剂的溶剂。由于PVC防化手套的抗磨损性能非常好,因此是石油化工、建筑和工业应用中的理想选择。
4.天然橡胶防化手套:具备良好的抗撕裂、刺穿、磨损和切割的性能,材料舒适且富有弹性,因此防化手套的柔曲性非常好,对几种化学品具有抗强酸、抗酮性,但不能接触油、油脂和碳氢化合物的衍生物,否则可能会膨胀或是降解。天然橡胶中含有可能引起过敏反应的乳胶蛋白,所以并不能适合每一位使用者。
5.聚乙烯醇防化手套:对大多数有机溶剂具有很好的防护作用,但是易溶于水,遇水后会降低其功效,而且材质较硬,加工不方便。
6.复合膜防化手套:该款防化手套可防护较多有害化学物渗透,可有效防护芳香族、酯、酮和氯等物质,是化学和石油化工实验室、喷溅清除、危险物质控制操作、照片冲洗、医药实验室和其他有害环境中的最佳选择。
7.乳胶防化手套:柔曲性非常好,抗撕裂,对几种化学品具有抗强酸、抗酮性,但不能接触油脂和碳氢化合物的衍生物。
但以上对一些极强酸强碱的防护能力还是不够,这样遇到一些极端环境下,比如氢氟酸,就容易对手部造成伤害,带来不可挽回的损失。
发明内容
为了克服现有技术的不足,本发明的目的是提供一种耐强酸强碱防护手套的制备方法。
为实现上述目的,本发明提供了如下方案:
一种耐强酸强碱防护手套的制备方法,包括:
将氯磺化聚乙烯与DMAC按照预设的质量比进行搅拌,得到适合手套浸渍的胶液;
利用手模和不同材质、规格、颜色的纱线手模进行编织,得到手套的内胆,并将所述内胆套在所述手模上进行预热;
将预热后的内胆浸渍一层水性聚氨酯;
待所述水性聚氨酯的涂层均匀后,放入50-100℃的烘箱中进行烘干30~100min;
根据耐酸碱的强度对烘干完成后的半成品进行至少一次的浸渍干燥过程;所述浸渍干燥过程包括浸渍一层所述胶液,并进行干燥;
将干燥后的半成品进行脱膜,得到耐强酸强碱防护手套。
优选地,所述预设的质量比为1:5。
优选地,将所述内胆套在所述手模上进行预热的温度为50~100℃。
优选地,在将预热后的内胆浸渍一层水性聚氨酯之后,还包括:
将涂覆完成的手模进行滴胶和匀胶动作,以使涂覆的水性聚氨酯的厚度均匀。
优选地,所述干燥的具体步骤包括:
对浸渍一层所述胶液的内胆进行60~90℃、时间为30~60min的第一次干燥;
第一次干燥后,进行90~120℃、时间为50~90min的第二次干燥。
根据本发明提供的具体实施例,本发明公开了以下技术效果:
本发明制备的防护手套,内胆不使用有机拒水剂,第一层涂层采用免洗水性聚氨酯,水性聚氨酯干燥后,第二层浸渍氯磺化聚乙烯溶液(氯磺化聚乙烯橡胶使用DMAC和二甲苯作为溶剂,将其溶解成氯磺化聚乙烯溶液),即可得到耐强酸强碱的防护手套。
