Description

一种防腐剂及其制备方法
技术领域
本发明涉及防腐试剂技术领域，尤其涉及一种防腐剂及其制备方法。
背景技术
目前市场上使用最为广泛的防腐剂是异噻唑啉酮产品，主要包括1,2-苯丙噻唑啉酮（BIT）和5-氯-2-甲基异噻唑啉酮（CMIT），BIT和CMIT产品占有工业防腐剂70%的市场。BIT本身比较稳定，不需要高浓度的硝酸铜、硝酸镁和氯化镁作为稳定剂，并且不易分解，长效性好，正在快速取代CMIT和其他防腐剂。
但是，现有的BIT产品都是强碱性产品，并含有20%-60%的挥发性有机物（VOC），对环境造成破坏。另外，由于强碱性特征，易造成中性和酸性产品的破乳和分解。市场上作为普通的BIT产品配方如下：BIT粉（85%）10-30%，二丙二醇溶剂20-60%，氢氧化钠3-10%，去离子水60-80%。该产品的pH为 12-14，易伤手，属于危险品，可能交联工业上使用的乳液和涂料，使用范围受限；另外，由于高含量的VOC，影响环境。
因此，亟需摸索出一种防腐剂，不含强碱和VOC，同时具有较高的稳定性。
发明内容
为了解决现有技术中BIT防腐产品碱性强，VOC含量高的问题，本发明的目的是提供一种防腐剂，不含强碱和VOC溶剂，同时具有较高的防腐性；为此，本发明将提供上述防腐剂的制备方法。
为了实现上述目的，本发明采用如下技术方案：
本发明的第一方面，提供一种防腐剂，由质量百含量的如下组分组成：BIT 8.5%-51%，稳定剂0.1%-1%，分散剂5%-20%，余量为水。
其中，所述BIT为粉状料。
优选的是，所述BIT以含有15%水分的粉状物料形式加入，避免BIT加入时带来的粉尘问题，降低物料加入对工作人员健康带来的威胁。
其中，所述稳定剂为天然的增稠剂。
优选的是，所述稳定剂选自纤维素醚、黄原胶、骨胶粉、海藻酸钠、罗望子胶、淀粉胶中的任意一种。
其中，所述分散剂为聚氧丙烯聚氧乙烯嵌段共聚物，简称为PO-EO-嵌段共聚物。
本发明的第二方面，提供上述防腐剂的制备方法，包括如下步骤：
S1，称取8.5%-51%的BIT，0.1%-1%的稳定剂，5%-20%的分散剂和水，其中BIT、稳定剂、分散剂和水的质量百分含量之和为100%；
S2，将BIT、水、分散剂和稳定剂依次加入罐体内，搅拌，研磨得到防腐剂。
其中，所述S2得到防腐剂的粒径为10-30微米。
将防腐剂的粒径研磨为10-30微米，提高防腐剂的分散性能，增大防腐剂与产品的接触面积，增强防腐效果。
稳定剂以骨架形式分散于BIT周围，BIT悬浮于稳定剂构成的骨架内，避免BIT发生沉淀；分散剂缠绕在BIT粒子外围，使得BIT亲水能力增强，增加了BIT与水的相容能力，BIT的分散性及稳定性增强，保证了防腐剂的有效性和持久性。
与现有技术相比，本发明实现的有益效果：本发明防腐剂将稳定剂与分散剂复配，提高了BIT的分散性、稳定性，保证了BIT的防腐功效，本发明防腐剂避免使用强碱和VOC溶剂，降低了防腐剂的危险性及对环境可能造成的损害；本发明防腐剂属于非危险品，运输方便；本发明防腐剂可以稀释成不同浓度，便于不同行业的使用，扩大了防腐剂的使用范围。
