Description

一种针刺无纺土工布及其制备方法
技术领域
本发明属于无纺布制造领域，具体涉及一种针刺无纺土工布及其制备方法。
背景技术
土工布具有优秀的过滤、排水、隔离、加筋、防护作用，具有重量轻、抗拉强度高、渗透性好、耐高温、抗冷冻、耐老化、耐腐蚀的特性。土工合成材料的应用起源于二十世纪五十年代，国内的土工布是国家的八五计划之一，我国于1998年颁布了《土工合成材料短纤针刺非织造土工布》（GB/T17638-1998）标准，目前土工布已经在多个领域得到了广泛应用。针刺无纺土工布主要用途是：江海湖河堤的护坡，围海造田、码头、船闸防汛抢险等工程，是通过返滤起到水土保持和防止管涌的有效途径。
发明内容
发明目的：本发明的目的在于针对现有技术的不足，提供一种针刺无纺土工布。
本发明的另一目的在于提供上述针刺无纺土工布的制备方法。
技术方案：为了达到上述发明目的，本发明具体是这样来完成的：一种针刺无纺土工布，包括以下重量份数的组分：40~50份的维纶，40~50份的锦纶，5~10份的氯纶和1~5份的硅油。
一种针刺无纺土工布的制备方法，包括以下步骤：
（1）将各原料加入往复式混炼挤出机中进行加热混炼，控制加热温度200~220℃，混炼4~8小时；
（2）将混炼后的混合物料从往复式混炼挤出机中挤出后进入单螺杆挤出机进行高压高温挤出，控制温度150~180℃；
（3）经过高压挤出后的混合物料通过过滤器过滤杂质，然后进入纺丝设备形成纤维；
（4）对生成的纤维进行裁剪，控制每条纤维长度不超过150mm，
（5）将纤维通过纺织机进行织布，最后成形后包装入库。
有益效果：本发明与传统技术相比，重量轻、成本低、耐腐蚀、具有反滤、排水、隔离、增强等优良性能，广泛用于水利、电力、矿井、公路和铁路等土工工程。
