Description

一种防刺服用面料及其制备方法
技术领域
本发明涉及防刺服技术领域，具体属于一种防刺服用面料及其制备方法。
背景技术
防刺服也称为防刀衣、防刃衣或防刃服，具有防刀割、防刀砍、防刀刺、防带棱角物体刮划、耐磨损、防盗等功能。穿着防刀衣时如遇磨损或用尖刀(利刃、尖锐物体等)切、割、砍、刮、蹭、划时可保护穿着者不受割伤、划伤、蹭伤、砍伤，适用于公安、武警、军队、保安、司机、玻璃加工等从业人员或老人、儿童、中小学生在有被割伤的危险下穿着。
目前的防刺服都是有多层结构组成，为了增强防刺服的防护能力，多数的防刺服内甚至使用金属丝，虽然防刺服的性能得到了大幅提升，但是防刺服过于笨重，不便于穿戴，同时其他的防护服主要通过增加防护服的层数来实现增强，这样同样造成了防护服过重，而且防护服面料层数的增加会导致防护服透气性降低，因此，需要设计一种层数少、防刺层性能好、透气性好的防护服面料，使穿戴防护服更加舒适。
发明内容
本发明的目的是提供一种防刺服用面料及其制备方法，克服了现有技术的不足，减少了防护服面料的层数，增加了透气性。
为解决上述问题，本发明所采取的技术方案如下：
一种防刺服用面料，包括由外而内层叠的第一防刺层、第二防刺层、增强层和内面料层，所述的第一防刺层上设有若干个互不接触的防刺孔，所述的防刺孔内壁上设有加强环。
其中，所述的第一防刺层和第二防刺层通过热熔胶贴合。
其中，所述的防刺孔为倒锥形结构。
优选地，所述的防刺孔的四周的第一防刺层的基体内设有防刺块，所述的防刺块均匀设置于防刺孔的四周。
更优选地，所述的防刺块内填充有非牛顿流体。
其中，所述的防刺孔之间的第一防刺层的基体内还设有增强纤维，所述的增强纤维在第一防刺层的基体内交错设置。
其中，所述的防刺孔的四周的第一防刺层的基体内设有防刺块，所述的防刺孔之间的第一防刺层的基体内还设有增强纤维，所述的增强纤维在第一防刺层的基体内交错设置。
优选地，所述的增强纤维穿过防刺块。
更优选地，所述的防刺块内填充有非牛顿流体。
非牛顿流体由0.5kg亚麻油、1.2kg石蜡、0.8kg琼脂、0.13kg十二烷基苯磺酸钠和3kg水混合而成，十二烷基苯磺酸钠为乳化剂，使石蜡和亚麻油在80℃下能均匀混合，降温后石蜡在十二烷基苯磺酸钠形成的乳胶粒内形成结晶，而亚麻油用于降低石蜡的熔点，琼脂作为非牛顿流体的形成剂。
制备防刺服用面料的方法，包括以下步骤：
S1，将两层表面具有多个半圆孔的聚丙烯片加热至80℃，然后将碳纤维热压到半圆孔之间的聚丙烯片上，碳纤维在聚丙烯片上交错设置，然后向半圆孔内注入非牛顿流体，降温至10℃，然后将两片聚丙烯片通过热压贴合，贴合过程中两片聚丙烯片上的半圆孔对应，形成防刺块，得到缓冲层；
S2，将缓冲层与第二防刺层通过热熔胶贴合，然后在90℃下在缓冲层上通过模压法形成防刺孔，得到防刺层，然后将防刺层与增强层和内面料层依次层叠，复合，得到防刺服用面料。
本发明与现有技术相比较，本发明的实施效果如下：
1、本发明的第一防刺层上设有防刺孔，在刀具穿刺该防护服时，防刺孔对刀具的穿刺方向可起到导向作用，同时防刺孔内的加强环具有较强的阻碍作用，使刀具穿刺防护服时的大部分能量可被抵消；
2、第一防刺层内还设有内部含有非牛顿流体的防刺块，在刀具穿刺时，防刺块具有泄力作用，使穿刺时的能力被抵消；此外，本发明的非牛顿流体由亚麻油、石蜡、琼脂、十二烷基苯磺酸钠和水混合而成，不仅具有非牛顿流体的特性，同时在石蜡的融化和凝固过程中还能起到控温作用；
3、本发明的防刺块除了具有防穿刺的作用，同时使第一防刺层上层形成了透气的通孔，使该面料的透气性得到增加，使使用该防刺服面料的衣物穿戴更加舒适；
4、本发明的制备方法简单，面料的层数少，原料易得，可应用于工业生产。
