Description
技术领域
本发明涉及耐海水抗菌油剂,具体涉及一种用于聚酯纤维的耐海水抗菌油剂。
背景技术
近年来,高强聚酯纤维材料在海洋中的应用越来越广,主要运用于海洋石油平台的固定绳索、舰船缆绳、鱼网、船帆、防护衣、皮划艇等。然而海洋环境是一个复杂的环境,其中盐度、海水温度、海洋污染物、海洋生物、溶氧量等都会影响聚酯纤维材料性能和和使用寿命,并制约其在海洋中的应用,如果没有高强度、强耐腐蚀性、无毒或低毒性的高性能材料作为保证,发展海洋科技产业将受到很大限制。因此,加强对纤维材料的耐海水腐蚀性能研究有着重要的意义。
化纤油剂是在化学纤维的纺丝、拉伸及后处理的过程中,为了减少丝束与导丝构件摩擦,消除在熔融纺丝过程中产生的静电,在纺丝、纺织前喷附在纤维表面上的化学助剂。
为了降低海水腐蚀、防止海洋附着生物的附着、减少耐海水抗菌层的起泡和脱落现象,研究者开始利用抗菌剂和活化物协同处理材料,如使用含氟活化物与金属抗菌剂含银、铜、锡类协同可获得优异的防腐抗菌效果。金属离子抗菌剂对各种病毒、细菌具有广谱,灭菌率高、安全性好、长效、不产生耐药性等特点,可以有效地杀死或抑制细菌的生长。但是有机抗菌剂耐热稳定性差,易挥发或水解,分解产物和挥发性组分容易对人类的皮肤和眼睛等造成刺激,故使用安全性差,寿命短。因此在纤维、木材、涂料、塑料(特别是工程塑料)加工成型等高温、高压、高剪切的加工条件下,有机抗菌剂的使用受到限制。例如汤庆国等发表了金属离子抗菌剂的抗菌效果及应用(研究环境与健康杂志.2005年3月第22卷第2期),具体公开了将过渡族金属离子、氧化物光触媒或有机抗菌组分担载到无机矿物上形成性能优异的新型抗菌材料,在改善人类的生活环境,提高人们健康水平方面将发挥越来越重要的作用。但是,金属抗菌剂易于析出,导致材料抗菌效果差,且对海洋产生金属污染。二十世纪八十年代初期,全世界防污涂料中所用抗菌剂为有机锡,有机锡高聚物不断发生水解和溶解,从而不断释放出有机锡毒料,达到长期防污的目的。但它对海水中的一些生物具有毒性,并引起生物发生变异,导致畸形,更为严重的是由于有机锡很稳定,经过很长时间也不易分解,它们经过海洋贝类和鱼类的渠道进入人类的食物链,直接危害人体的健康。因此近年来各沿海国家纷纷立法限制有机锡的使用。
目前,由于对含有机锡抗菌剂的限制越来越严格,无锡抗菌剂的市场潜力也越来越大。世界上很多国家正在加快开发研制不含锡的抗菌剂。但是值得指出的是,以氧化亚铜类加入辅助毒剂(如氧化吡啶硫酚的锌、铜络合物等)为抗菌剂,海洋中或海港中铜元素的大量积累,会导致海藻的大量死亡。且有研究表明,铜加上辅助毒剂对海洋生物的危害几乎等同于有机锡,因此,该类抗菌剂最终也将被禁用。银离子抗菌性能较强,且对细菌不易产生抗药性突变,安全性好。研究表明,银离子抗菌剂急性毒性(LD50)大于2000mg/kg,皮肤一次刺激呈无刺激性反应,基因突变呈阴性。但材料中银离子不够稳定,在紫外线照射下银离子易还原为金属银,银氧化后制品变黑,变灰,抗菌性能下降。
为避免金属类抗菌剂的缺陷,降低抗菌剂的价格,保证其抗菌广谱性,因此研发出聚酯纤维用绿色环保永久型的耐海水抗菌油剂逐步成为当前研究的热点,也是未来海洋领域的发展方向。
发明内容
本发明的目的在于针对现有技术的不足,提供一种用于聚酯纤维的耐海水抗菌油剂,在油剂组分中添加防腐剂和表面活化物,改善了材料的防腐抗菌、耐久性、超疏水和抗静电等性能。

作为优选,所述抗静电剂为阳离子抗静电剂、阴离子抗静电剂或非离子型抗静电剂。进一步优选,所述的阳离子抗静电剂为长链的烷基季铵(如聚季铵盐-11)、磷盐类,阴离子抗静电剂为烷基磺酸或磷酸等,非离子型抗静电剂为乙氧基化脂肪族烷基胺类等。
作为优选,所述的耐海水抗菌油剂的组成按质量份数计,包括12~18份五元共聚嵌段硅油,1~5份邻苯二甲酸二异壬酯,1~5份壬基酚聚氧化乙烯醚,1~15份聚季铵盐-11,10~20份聚硅氧烷季铵盐-16,5~13份聚氧化乙烯醚和40~60份蒸馏水。
