Description
技术领域
本发明涉及屋面建筑涂料领域，具体为一种屋面反射隔热涂料。
背景技术
反射隔热涂料通过高效反射太阳光来达到隔热目的。薄层隔热反射涂料是这类涂料的代表。涂料能对400nm--2500nm范围的太阳红外线和紫外线进行高反射，不让太阳的热量在物体表面进行累积升温，又能自动进行热量辐射散热降温，把物体表面的热量辐射到太空中去，降低物体的温度，即使在阴天和夜晚涂料也能辐射热量降低温度，同时在涂料中放入导热系数极低的空心微珠，隔绝热能的传递，即使在大气温度很高时也能隔住外部热量向物体内部传导，三大功效保证了涂刷涂料的物体降温，确保了物体内部空间能保持持久恒温的状态。隔热防晒涂料在阳光强烈时，涂料可以降低物体表面温度20℃以上，阴天和夜晚可以降温在3℃以上或是降低到和大气温度一致。涂刷涂料对于有细小的裂纹的物体有很好的防水、防渗漏作用。
现有的反射隔热涂料均采用单一的隔热手段对表面进行隔热，会导致隔热效果不理想，从而导致涂料表面的温度升高，进而影响到涂料的功能，而且在表面易于进行摩擦，破坏涂料的膜结构，从而使隔热出现漏洞。

一种屋面反射隔热涂料，包括以下制备步骤：
S1.原料准备
将隔热填料、热反射填料、连接填料、辐射隔热填料按照百分比进行配比进行混合，形成功能性填料，然后将弹性丙烯酸共聚物、功能性填料、助剂按照百分比进行称量，根据差值，确定水的用量；
S2.进行混合

其性能结果如表二所示：
表二实施例与对比例的性能结果
采用本发明的屋面反射隔热涂料制成的涂料，各项物性均优于现有技术涂料形成的涂膜的物性，而且隔热性能更好，表面能够隔绝较多热量，且与外界热量交换缓慢。通过连接填料，使涂料的连接性能增强，可以有效防止屋面开裂形成漏水。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
