Description

一种高强度滤料及其制备方法
技术领域
本发明涉及滤料及其制备技术领域，具体为一种高强度滤料及其制备方法。
背景技术
滤料经常用于除尘和过滤等设备中，在进行过滤时，为了便于提高过滤效率，一般会在待过滤的一侧施加一定的压力，以便于待过滤的液体通过滤料，专利号为CN202210848131.X的发明专利公开了一种高强度工业滤料基布及其制备工艺，该专利中，针对不同的过滤环境需要采用不同过滤精度的滤料，滤料的过滤精度取决于其编织密度，因此需要通过不同编织密度的针织机进行生产加工，当过滤精度增加时，会导致液体难以通过，因此会在待过滤的一侧施加更大的压力，现有的滤料强度较低，在长时间使用后容易破损失效；另外，现有的滤料在不使用时一般大量存放在仓库内，一旦发生起火现象，容易造成较大的火灾，存在一定的安全隐患。
发明内容
(一)解决的技术问题
针对现有技术中存在的问题，本发明提供了一种高强度滤料及其制备方法，以解决背景技术中提到的技术问题。
(二)技术方案
为实现上述目的，本发明提供如下技术方案：一种高强度滤料，包括基布层，所述基布层的上方和下方分别设有第一抗静电层和第二抗静电层，第一抗静电层的上表面设有第一阻燃层，第二抗静电层的下表面设有第二阻燃层，第一抗静电层和基布层之间设有第一粘合层，第一抗静电层和第一阻燃层之间设有第二粘合层，第二抗静电层和基布层之间设有第三粘合层，第二抗静电层和第二阻燃层之间设有第四粘合层，所述基布层包括纺织线束。
优选的，所述纺织线束包括芳纶纱线、玻璃纤维纱线和碳复合纤维纱线，便于提高纺织线束的强度。
在进一步中优选的是，所述基布层设置有若干个，且若干个基布层从上到下依次交错设置，便于提高整体的强度和过滤精度。
在进一步中优选的是，相邻两个所述基布层之间均设有第五粘合层，防止松散。
在进一步中优选的是，所述第一粘合层、第二粘合层、第三粘合层、第四粘合层和第五粘合层的材料相同，便于制备材料。
本发明提供了一种高强度滤料的制备方法，其制备方法包括：
S1：将纺织线束作为经线和纬线，并通过针织机编织成基布层；
S2：将多个基布层交错铺设，形成多层基布层，相邻基布层的纤维孔交错覆盖；
S3：将聚酯纤维纱线纺织成纤维网，并经过浸泡晾干处理，形成第一抗静电层和第二抗静电层；
S4：将一种或多种阻燃纱线纺织制成第一阻燃层和第二阻燃层。
优选的，所述S1中的纺织线束通过芳纶纱线、玻璃纤维纱线和碳复合纤维纱线缠绕制成，便于提高整体的强度。
在进一步中优选的是，所述S3中的浸泡晾干处理包括，将纤维网浸泡在导电性树脂内，使其表面附着导电性树脂，再将其取出晾干，便于抗静电。
在进一步中优选的是，所述S4中的所述一种或多种阻燃纱线包括阻燃聚丙烯腈纤维纱线和阻燃涤纶纤维纱线中的一种或多种，便于阻燃。
在进一步中优选的是，所述S4之后还包括S5：将丙烯酸丁酯、氧化锌、碳酸氢钠、苯乙烯和醋酸乙烯酯按照比例混合制成第一粘合层、第二粘合层、第三粘合层、第四粘合层和第五粘合层，分别涂抹在第一抗静电层和基布层之间、第一抗静电层和第一阻燃层之间、第二抗静电层和基布层之间、第二抗静电层和第二阻燃层之间以及相邻两个所述基布层之间，将若干个基布层、第一抗静电层、第二抗静电层、第一阻燃层和第二阻燃层之间粘合在一起，并将其放在热合设备中进行热合加固，形成滤料，便于进行连接。
(三)有益效果
与现有技术相比，本发明提供了一种高强度滤料及其制备方法，具备以下有益效果：
1、本发明中设置有若干层基布层，且若干层基布层之间交错设置，相邻基布层的纤维孔交错覆盖，可以通过增加基布层的数量，进而增加该整体的密度，进而提高该整体的过滤精度；
2、本发明中在增加基布层数量的同时，可以增加整体的强度，当需要该整体的过滤精度较大时，待过滤液体不易从基布层处穿过，需要增加压强，此时该整体的强度要求也会随之增加，增加基布层可以保证该整体的强度符合强度需求；
3、本发明中设置有第一阻燃层和第二阻燃层，在堆放起火时，可以有效防止火灾的进一步蔓延，还设置有第一抗静电层和第二抗静电层，可以抵抗灰尘所携带的静电；
4、本发明中所述的制备方法中将多个基布层交错铺设，形成多层基布层，相邻基布层的纤维孔交错覆盖，便于通过更换基布层的数量和排布位置，来调整该滤料的过滤精度。
