Description
技术领域
本发明涉及防护服技术领域,尤其是一种纯棉阻燃防护服的制备方法。
背景技术
在消防、冶炼等高温行业,强大的辐射热能使普通服装迅速受热熔融、分解并燃烧,容易灼伤操作人员的肌肤,威胁其生命安全。阻燃服由于在面料中增加了阻燃纤维或者在面料上涂覆了阻燃剂,从而能够大大减慢燃烧速度,在移动后马上自行熄灭,而且燃烧部分迅速炭化而不产生熔融、滴落或穿洞,给人时间撤离燃烧现场或脱掉身燃烧的衣服,减少或避免烧伤烫伤,达到保护的目的。阻燃服因此成为高温作业人员的必要防护品之一。
现有的纯棉阻燃防护服,其同常将面料或者防护服直接放入阻燃剂中浸泡,然后取出后烘干,其效率很低。同时,对于前者,由于面料在加工过程中可能会损坏阻燃布料,从而造成风险隐患。对于后者,其在厚度较大,而且为双层或多层,内表面与外表面阻燃剂分布不一致,从而倒置内部的阻燃性能较差。并且多余的阻燃液挤出后不再回收,从而造成浪费。
发明内容
本发明提供一种阻燃防护服的制备方法,其制备的阻燃服阻燃剂分布均匀,具有良好的阻燃效果,而且更加耐洗涤。
一种阻燃防护服的制备方法,
A.将布料制成衣服;
B.将衣服在放有阻燃剂的浸泡池中浸泡;
C.将衣服放置在工作台上,通过压力机构对衣服施加压力;
D.衣服进入第一烘干区以100-120℃对衣服进行预烘干;
E.在第一烘干区内向衣服通入氨气;
F.衣服移出烘干区,浸入双氧水中;
G.进入第二烘干区,以150℃烘干10分钟,然后将衣服烫平。
进一步地,所述步骤B中,所述阻燃剂为柔软剂、渗透剂、四氧羟甲基氯化磷按照体积比为1:5:50混合而成。
进一步地,所述步骤C中,工作台为设有通孔转动带,当衣服放置在工作台上,衣服可随着工作台运动,工作台下方设有集液槽,集液槽侧部设有与浸泡池联通的出口,衣服中挤出的液体经通孔、集液槽回流至少浸泡池中。
进一步地,所述压力机构包括支架,位于支架上方的充气空间、位于支架下方的压件,所述压件与支架固定连接的压辊,所述压辊包括金属的内辊和覆盖于金属内辊表面的外辊,向所述充气空间充气后,充气空间膨胀,使得压辊随支架向下运动,挤压工作台上的衣服,同时转动压辊,使得衣服随压辊向前运动并将多余的阻燃剂挤出流回浸泡池中,当充气空间排气后,充气空间收缩,使得压辊随支架向上运动离开工作台。
进一步地,所述步骤E中,将衣服悬挂起来,所述氨气设有多个入口,至少一个入口位于衣服的水平投影面内,所述氨气从入口垂直向上喷出,氨气与衣服接触后从位于衣服顶部的排气口排出,多个入口氨气的通入量为400L/min,氨气持续通入时间为90秒。
进一步地,所述步骤F中,先配置60g/L的双氧水,再将衣服进入双氧水中浸泡。
采用以上技术方案,具有以下技术效果:
1.先制成衣服在浸泡阻燃剂,从而有效防止在衣服生产过程中造成阻燃剂的损坏,通过设置两个烘干区,不但有利于氨气与阻燃剂发生反应,而且是的阻燃剂充分交联,在第一烘干区内通入氨气,有效利用第一烘干区相对较高的温度,可以加速氨气与阻燃剂发生反应,从而提高了效率,有效实现了能源的再利用。
2.通过设有通孔的工作台和连接至浸泡池的集液槽,使得多余的阻燃剂自动回流至浸泡池重复利用,有效降低了成本。
3.通过充气带动压辊挤压衣服,使得衣服受力均匀,衣服中的阻燃剂更加均匀,最终衣服的阻燃效果更好。
4.由于至少一个入口位于衣服的水平投影面内,从而使得氨气与衣服的内表面和外表面均充分接触,利用第一烘干区残留的温度,只需要持续通入90秒的氨气即可,有效提高了氨气与阻燃剂的反应速度,而且相对于间断通入氨气具有连贯的交联效果。

通过设有通孔的工作台和连接至浸泡池的集液槽,使得多余的阻燃剂回流至浸泡池重复利用,有效降低了成本。
通过充气带动压辊挤压衣服,使得衣服受力均匀,衣服中的阻燃剂更加均匀,最终衣服的阻燃效果更好。
D.衣服进入第一烘干区,将衣服悬挂起来,以100-120℃对衣服进行预烘干;

F.衣服移出烘干区,先配置60g/L的双氧水,再将衣服进入双氧水中浸泡;
G.进入第二烘干区,以150℃烘干10分钟,然后将衣服烫平。
