Description

一种耐碱性弹性涂料
技术领域
[0001] 本发明涉及涂料的技术领域,特别涉及弹性涂料的技术领域。背景技术
[0002] 弹性涂料是以合成树脂乳液为基料,与颜料、填料及助剂配制而成,施涂一定厚度后,具有弥盖因基材伸缩产生细小裂纹的有弹性的功能性涂料。通常包括溶剂型、乳液型及无机型弹性涂料。其中溶剂型、乳液型弹性涂料延伸率高,成膜效果好,但强度、硬度相对较差,耐候、耐热性差,而无机型弹性涂料成膜效果相对较差,弹性一般较低。发明内容
[0003] 本发明的目的在于提出一种强度、硬度较高,耐热、耐候性优良,同时具有较好耐碱性的有机弹性涂料。
[0004] 本发明的技术方案如下:

[0006] 优选的是:所述偶联剂为硅烷偶联剂。
[0007] 另外优选的是:所述分散剂为聚乙烯醇。
[0008] 另外优选的是:所述成膜助剂为丙二醇乙醚。
[0009] 另外优选的是:所述润湿剂为丙二醇。
[0010] 另外优选的是:所述组分按质量份计,包括纯丙乳液30〜50份,分散剂0.1〜1.0 份,润湿剂5〜10份,偶联剂0.5〜1.5份,成膜助剂0.5〜2.5份,羟甲基纤维素0.1〜0.5份, 煅烧高岭土5〜15份,气相二氧化娃1〜5份,去离子水5〜15份,氧化|丐0.1〜0.3份,火山灰 0.02 〜0.05 份。
[0011] 另外优选的是:所述弹性涂料的组分还包括消泡剂和/或流平剂。
[0012] 本发明具有以下有益效果:[〇〇13] (1)涂膜具有500%以上的延伸率,能弥盖细微裂缝;
[0014] (2)涂膜具有较高的硬度、强度,良好的耐热、耐候、耐老化性;
[0015] (3)对基层的附着力较高,具有良好的耐碱性。具体实施方式
