Abstract

一种高效防尘剂，它由非离子表面活性剂月桂醇聚氧乙烯醚，阴离子表面活性剂1、2-二正丁基萘-6-磺酸钠和水所组成，本发明适应性强，对褐煤、焦煤、二氧化硅粉尘均具有显著的降尘效果，与目前采矿中常用的水相比可显著提高降尘效率。

Description

本发明属于采矿防尘技术
矿山开采过程中会产生大量的粉尘，过量的粉尘不仅会损害现场操作人员的身体健康，有时在其它因素作用下，还可能发生爆炸事故。目前国内大都采用喷水降尘的方法来解决这一问题。但水对粉尘的润湿程度低，降尘效果很不理想。实验表明，当粉尘密度为200-300毫克/立方米时，水的降尘率为围50%左右，大大高于国家规定的10毫克/立方米安全标准。近年来国内外都在研究各种类型的防尘剂以解决上述问题，如美国专利（U.S    pat    4，425，252    1984.1.10）介绍了一种降尘剂，它由壬基酚聚氧乙烯醚、十二烷基苯磺酸钠、异丙醇、乙二醇二丁醚与水相混合而成。该防尘剂虽然具有一定的降尘效果，但由于组成复杂配制很不方便，而且药剂成本较高。
本发明的目的是研制一种降尘效率高，适应性强，造价低廉的矿山防尘剂。
本发明利用非离子表面活性剂和阴离子表面活性剂所具有的润湿性，以及两者混合后的协同效应，采用月桂醇聚氧乙烯醚和1、2-二正丁基萘-6-磺酸钠与水相混合制成高效防尘剂。配制时可根据配方将上述两种表面活性剂相混合，然后按配方比例加入水，并搅拌混合均匀后即可使用。
本发明制得的高效防尘剂与目前采矿中普遍使用的水相比可显著地提高降尘率。与前述美国专利，对普通煤沉降速度3分45秒相比，提高沉降速度2分33秒（见表1），并且按目前国内原料价格计算，每吨防尘剂（不含水）成本只是其三分之一，用本防尘剂经沉降试验及模拟粉尘现场喷淋降尘试验（采用滤膜式测尘仪测式）所得到的结果表明，本 防尘剂不仅对褐煤粉尘有显著的降尘效果，而且对煤焦油含量较高的焦煤，以及二氧化硅粉尘也有显著的降尘效果（见表1）。本发明制备方发简便，成本低廉，而且可制成水溶液作为商品出售，也可在采矿现场配制后直接使用。
