Description

一种透明抗菌亲水涂料
技术领域
本发明涉及涂料技术领域，尤其是涉及一种透明抗菌亲水涂料。
背景技术
随着人们的生活水平不断的提高，人们对生活卫生质量的要求也越来越高，如何能够有效的抗菌、除菌是人们对现代生活提出的挑战。抗菌涂料行业目前仍处在发展阶段，解决抗菌材料在涂料中的应用工艺，是摆在涂料行业面前共同的课题。
发明内容
本发明所要解决的技术问题是提供一种高硬度、亲水性好、具有抗菌功能的无机涂料，其适合用于厨具、卫具及玻璃等表面处理，具有保护基材，使基材表面易清洁并有抗菌作用的透明抗菌亲水涂料。
本发明的技术方案为：一种透明抗菌亲水涂料，包括以下组分：硅酸盐或溶胶中的至少一种、纳米氧化物分散液、碱金属的磷酸盐、无机抗菌剂、抑制剂、润湿剂和溶剂；其中，
所述硅酸盐为硅酸锂、硅酸钠、硅酸钾、硅酸钙或硅酸锆中的至少一种；所述溶胶为硅溶胶、铝溶胶中的至少一种；
所述纳米氧化物分散液为气相二氧化硅分散液、纳米氧化钙分散液、纳米碳酸钙分散液、纳米氧化锌分散液或纳米氧化锆分散液中的至少一种；
所述碱金属的磷酸盐为磷酸镁、磷酸铝、磷酸钠、磷酸钾或磷酸钙中的至少一种；
所述无机抗菌剂为纳米铜或纳米银中的至少一种；
所述抑制剂为三乙醇胺、二乙醇胺或一乙醇胺中的至少一种；
所述润湿剂为乙二醇单丁醚、二乙二醇单丁醚、改性硅氧烷或聚山梨醇酯中的至少一种；
所述润湿剂为乙二醇单丁醚、二乙二醇单丁醚、改性硅氧烷或聚山梨醇酯中的至少一种；
所述溶剂为水。
所述抗菌剂优选为纳米银，其添加量为涂料总量的0.01％-2％。
优选地，所述纳米银的添加量为涂料总量的为0.05％-1％。
所述抑制剂的添加量为涂料总量的1％-10％。
所述润湿剂的添加量为涂料总量的0.01％-2％。
优选地，所述润湿剂的添加量为涂料总量的0.05％-1％。
优选地，本发明的透明抗菌亲水涂料，其包括下列按质量百分比的组分：硅酸锂0-10％、硅酸钾0-30％、硅溶胶0-20％、铝溶胶0-20％、纳米碳酸钙分散液1-5％、磷酸铝1-5％、纳米银0.01％-2％、二乙醇胺1％-10％、乙二醇单丁醚0.01％-2％、水余量。
优选地，本发明的透明抗菌亲水涂料，其包括下列按质量百分比的组分：硅酸锂7％、硅酸钾21％、硅溶胶12％、纳米碳酸钙分散液2％、磷酸铝1.6％、纳米银0.4％、二乙醇胺5.5％、乙二醇单丁醚1.5％、水49％。
本发明所述的硅酸盐与溶胶对涂料的成模性具有影响，硅酸盐与溶胶的比例优选为1:(0.4-1)，溶胶的含量不宜超过硅酸盐的含量，过多会影响涂料的成模性，使得涂料附着力差涂层易脱落、耐水煮和耐酸碱性能差。
本发明中所述的纳米氧化物分散液具有耐水、耐洗刷、耐污性能，有助于涂料成膜，提高涂料涂层的耐摩擦性、耐洗刷性。
本发明所述碱金属的磷酸盐有助于提高涂料的亲水性。
本发明的有益效果为：本发明透明抗菌亲水涂料采用无机组分，通过各组分的协同作用，可保持涂料涂层具有良好的抗菌性能和持续的亲水性能，且涂料涂层为透明涂层、具有高硬度、耐摩擦性，适合用于各种金属、玻璃、陶瓷的表面处理，尤其适用于厨具、卫具，具有保护基材，使基材表面易清洁、耐洗刷，满足人们对生活卫生质量的要求。
具体实施方式
下面结合具体实施例对本发明作进一步阐述。
实施例1至实施例5的透明抗菌亲水涂料，其各组分配比如下表1：
表1
性能测试：按照表1中的实施例1～实施例5的配方制备涂料，制备所得的涂料采用喷涂方式在120mm×150mm的拉丝不锈钢板上制作涂层；先在低温下(如50℃)烘烤10min，在250℃烘烤30min；实施例1～5的检测性能见表2。
表2
从上述性能检测结果可得：实施例1至实施例4涂层外观为透明，抗菌性合格，实施例1涂层亲水角低至6°，亲水性好，且经过2000次摩擦后亲水角为15°，变化不大，可见涂层具有高耐磨性；其次，实施例3因为无使用硅溶胶因而其耐水煮、耐酸碱性较差，而实施例4由于溶胶含量(硅溶胶和铝溶胶)大于硅酸盐，涂层各性能差，可见溶胶含量过多会影响涂料的附着力；实施例5的纳米银含量较实施例1至实施例4含量均少，测试结果是抗菌性不合格，可见纳米银的含量不可过少。
以上所述，仅为本发明的较佳实施例，并不用以限制本发明，凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同替换和改进，均应包含在本发明技术方案的保护范围内。
