Description

一种用于手持式吸尘器的耐水洗滤尘片
技术领域
本发明涉及一种过滤材料，具体涉及一种用于手持式吸尘器的耐水洗滤尘片。
背景技术
过滤材料在手持式吸尘器中是一种重要的高频次使用的部件，但出于成本控制等因素，各个生产厂家对于更优质高效的过滤材料的研发投入不高，然而低成本的滤尘片在使用一段时间后，易发生堵塞，此时用户一般会选择清洗滤尘片并将其晾干；然而在此过程中，滤尘片将产生不可逆的形变，导致排风性能下降，对灰尘的过滤效果受到影响，细小粉尘在风力的作用下，易从形变处穿过过滤片排出吸尘器，从而对室内环境造成二次污染，影响了用户的呼吸健康。
发明内容
针对现有技术的不足之处，本发明的目的在于提供一种用于手持式吸尘器的耐水洗滤尘片，其结构简单，耐水洗，不易变形，使用寿命高。
本发明的技术方案概述如下：
一种用于手持式吸尘器的耐水洗滤尘片，其包括第一耐水洗纤维层和第二耐水洗纤维层，其中，所述第一耐水洗纤维层和第二耐水洗纤维层中的纤维丝分别呈单向排列且相互垂直；
其中，所述第一耐水洗纤维层包括以下重量份的材料：
聚氨酯纤维丝 100重量份；
乙烯-丙烯共聚物纤维丝 18～22重量份；
环氧树脂 6～8重量份；
所述第二耐水洗纤维层包括以下重量份的材料：
乙烯-乙酸乙烯酯共聚物 100重量份；
聚丙交酯纤维丝 20-30重量份。
优选的是，所述的用于手持式吸尘器的耐水洗滤尘片，其中，所述乙烯-丙烯共聚物纤维丝中，乙烯含量为18～20wt％。
优选的是，所述的用于手持式吸尘器的耐水洗滤尘片，其中，所述乙烯-丙烯共聚物纤维丝的数均分子量为10000～12000。
优选的是，所述的用于手持式吸尘器的耐水洗滤尘片，其中，所述聚氨酯纤维丝的数均分子量为12000～18000。
优选的是，所述的用于手持式吸尘器的耐水洗滤尘片，其中，所述环氧树脂的数均分子量为5000～8000。
优选的是，所述的用于手持式吸尘器的耐水洗滤尘片，其中，所述聚丙交酯纤维丝的数均分子量为8000～10000。
优选的是，所述的用于手持式吸尘器的耐水洗滤尘片，其中，在所述聚丙交酯纤维丝中，L-丙交酯∶D-丙交酯＝5～6∶1。
优选的是，所述的用于手持式吸尘器的耐水洗滤尘片，其中，所述乙烯-乙酸乙烯酯共聚物中，乙烯含量为34～36wt％。
优选的是，所述的用于手持式吸尘器的耐水洗滤尘片，其中，所述乙烯-乙酸乙烯酯共聚物的数均分子量为10000～12000。
本发明的有益效果是：本案通过采用双材质的耐水洗纤维层结合，并通过对耐水洗纤维材料的改进，使滤尘片具备了优异的耐水洗功能，其在长期使用后保持不变形，易清洁，且滤尘和排风性能不受影响。
具体实施方式
下面结合实施例对本发明做进一步的详细说明，以令本领域技术人员参照说明书文字能够据以实施。
本案提出一实施例的用于手持式吸尘器的耐水洗滤尘片，其包括第一耐水洗纤维层和第二耐水洗纤维层，其中，第一耐水洗纤维层和第二耐水洗纤维层中的纤维丝分别呈单向排列且相互垂直；
其中，第一耐水洗纤维层包括以下重量份的材料：
聚氨酯纤维丝 100重量份；
乙烯-丙烯共聚物纤维丝 18～22重量份；
环氧树脂 6～8重量份；
聚氨酯纤维丝具有出色的透气性能和滤尘性能。乙烯-丙烯共聚物纤维丝与其结合后，可用于改善聚氨酯纤维丝的耐水洗能力，并能够有效增加滤尘片的结构稳定性，使其不易产生变形。环氧树脂使其具有自粘性，以用于与第二耐水洗纤维层粘结固定。
第二耐水洗纤维层包括以下重量份的材料：
乙烯-乙酸乙烯酯共聚物 100重量份；
聚丙交酯纤维丝 20-30重量份。
乙烯-乙酸乙烯酯共聚物在与聚丙交酯纤维丝结合后，可在不影响纤维层透气和滤尘性能的前提下，增加纤维层的机械强度和结构韧性，从而增加滤尘片的抗风性能，以减少形变，提高滤尘片的过滤效果。此外，乙烯-乙酸乙烯酯共聚物的引入可帮助纤维层产生更多更小的微孔结构，以进一步降低风阻，并增加对极细小颗粒的过滤效果。
作为本案又一实施例，其中，乙烯-丙烯共聚物纤维丝中，乙烯含量优选为18～20wt％。
作为本案又一实施例，其中，乙烯-丙烯共聚物纤维丝的数均分子量优选为10000～12000。
作为本案又一实施例，其中，聚氨酯纤维丝的数均分子量优选为12000～18000。
作为本案又一实施例，其中，环氧树脂的数均分子量优选为5000～8000。
作为本案又一实施例，其中，聚丙交酯纤维丝的数均分子量优选为8000～10000。
作为本案又一实施例，其中，在聚丙交酯纤维丝中，L-丙交酯∶D-丙交酯＝5～6∶1。
作为本案又一实施例，其中，乙烯-乙酸乙烯酯共聚物中，乙烯含量优选为34～36wt％。
作为本案又一实施例，其中，乙烯-乙酸乙烯酯共聚物的数均分子量优选为10000～12000。
表一列出不同实施例和对比例的尘袋的主要参数及其性能测试数据：
表一
尽管本发明的实施方案已公开如上，但其并不仅仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节。
