Description

一种外墙漆及其制备方法
技术领域
本发明涉及一种外墙漆及其制备方法。
背景技术
随着经济建设的不断发展， 对特殊功能涂料的需求不断增加。发光涂料作为功能涂料的一种，越来越受到人们的青睐。发光涂料的性能主要取决于发光材料和基体树脂的吸光、发光性能，此外，还需要适当的助剂改善其施工性。涂料常用的树脂均可用于发光涂料。由于现有的长余辉发光粉的累积寿命一般在15a 左右，所以与其配伍的成膜物要具有较好的光透射率、耐光耐候性。氟碳树脂较一般树脂具有优异的耐候性、耐腐蚀及抗污染性等一系列优点，为开发高性能发光涂料提供了有力条件。
发明内容
有鉴于此，本发明要解决的技术问题在于提供一种以氟碳树脂为原材料的外墙漆，其具有氟碳树脂的耐候性、耐腐蚀及抗污染性的同时具有更好的发光性。
本发明的一种外墙漆及其制备方法，包括如下重量分数的组分：氟碳树脂40-60份；蜡液20-30份；醋酸丁酸纤维素10-15份；气相白炭黑5-9份；分散剂3-6份；防沉助剂2-5份；铝酸盐系蓄光颜料10-12份。
进一步，所述铝酸盐系蓄光颜料包括SrAl2O4：Eu2+、H 3BO 3和正硅酸甲醋。
优选的，所述铝酸盐系蓄光颜料中SrAl2O4：Eu2+、H 3BO 3和正硅酸甲醋的重量比为8:1:0.5。
进一步，包括如下重量分数的组分：氟碳树脂55份 ；蜡液26份；醋酸丁酸纤维素13份；气相白炭黑7份；分散剂5份；防沉助剂3份；铝酸盐系蓄光颜料11份。
本发明的一种外墙漆的制备方法，按重量份数称取原料，将氟碳树脂加入搅拌容器内并放入蜡液、醋酸丁酸纤维素、分散剂，在600-700转/分的转速下搅拌均匀，然后在搅拌容器内投入气相白炭黑、防沉助剂，在700-800转/分的转速下搅拌均匀，最后再容器内加入铝酸盐系蓄光颜料并以900-1000转/分的转速下搅拌，待涂料完全分散均匀，检测合格后，即得成品。
本发明的有益效果：本发明的一种外墙漆，包括如下重量分数的组分：氟碳树脂40-60份 ；蜡液20-30份；醋酸丁酸纤维素10-15份；气相白炭黑5-9份；分散剂3-6份；防沉助剂2-5份；铝酸盐系蓄光颜料10-12份。。与相应的，本发明还提供一种外墙漆的制备方法，由制备方法按照上述原料组分制得的外墙漆具有氟碳树脂的耐候性、耐腐蚀及抗污染性的同时又具有更好的发光性。
具体实施方式
实施例1
本实施例的外墙漆，包括如下重量分数的组分：氟碳树脂40份 ；蜡液20份；醋酸丁酸纤维素10份；气相白炭黑5份；分散剂3份；防沉助剂2份；铝酸盐系蓄光颜料10份。
进一步，所述铝酸盐系蓄光颜料包括SrAl2O4：Eu2+、H 3BO 3和正硅酸甲醋。
优选的，所述铝酸盐系蓄光颜料中SrAl2O4：Eu2+、H 3BO 3和正硅酸甲醋的重量比为8:1:0.5。
本实施例的外墙漆的制备方法，按上述重量份数称取原料，将氟碳树脂加入搅拌容器内并放入蜡液、醋酸丁酸纤维素、分散剂，在600-700转/分的转速下搅拌均匀，然后在搅拌容器内投入气相白炭黑、防沉助剂，在700-800转/分的转速下搅拌均匀，最后再容器内加入铝酸盐系蓄光颜料并以900-1000转/分的转速下搅拌，待涂料完全分散均匀，检测合格后，即得成品。
实施例2
与实施例1不同的是，本实施例的外墙漆包括如下重量分数的组分：氟碳树脂60份；蜡液30份；醋酸丁酸纤维素15份；气相白炭黑9份；分散剂6份；防沉助剂5份；铝酸盐系蓄光颜料12份。
实施例3
与实施例1和实施例2不同的是，本实施例的外墙漆，包括如下重量分数的组分：氟碳树脂55份 ；蜡液26份；醋酸丁酸纤维素13份；气相白炭黑7份；分散剂5份；防沉助剂3份；铝酸盐系蓄光颜料11份。
对照例1
采用天津某涂料有限公司生产的荧光外墙漆。
为了说明本发明的外墙漆的发光能力，采用余辉亮度（mcd/m2）来进行对比。将实施例1-3的外墙漆与对照例1在相同的漆膜厚度、相同的光源条件下进行试验，结果如表1。
表1实施例1-3与对照例1的余辉亮度对比
实施例1 实施例2 实施例3 对照例1
余辉亮度（mcd/m2） 214 217 228 196
由表1可以看出，本发明的外墙漆的余辉亮度显著高于市场同类产品，即发光能力强，特别是实施例3的外墙漆尤为突出。
对照例2
与实施例3唯一的不同在于铝酸盐系蓄光颜料的成分不同，本对照例采用重庆某颜料公司生产的铝酸盐系蓄光颜料作为生产外墙漆的原料。
表2实施例3与对照例2的余辉亮度对比
实施例3 对照例2
余辉亮度（mcd/m2） 228 210
由表2可以看出，虽然对照例2比对照例1的发光能力要强，但是由于其没有采用本发明的铝酸盐系蓄光颜料，即包括SrAl2O4：Eu2+、H 3BO 3和正硅酸甲醋的铝酸盐系蓄光颜料，导致对照例2的外墙漆发光能力较本发明较差。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
