本发明公开了一种环氧砂浆，其由环氧树脂和砂浆混合而成；所述砂浆包含：18～25重量份硅酸盐水泥，60～70重量份细沙，0～5重量份熟石灰，0.1～0.2重量份疏水剂，0.03～0.05重量份引气剂，以及一定量的清水。本发明还提供上述环氧砂浆的制备方法和应用。本发明环氧砂浆能够粘合混凝土和PVC防水卷材，可将PVC防水卷材与混凝土反坎紧实的粘粘在一起，避免两者直接粘粘不牢的问题。PVC防水卷材与混凝土反坎粘合牢固，不会在施工一端时间之后发生防水卷材开缝或脱节的情况，防水效果长期可靠。

Description

环氧砂浆及其制备方法和应用
技术领域
本发明涉及环氧砂浆及其制备方法和应用。
背景技术
建筑物会设置变形缝，变形缝需要覆盖防水卷材进行防水，从耐久性和防火性上考虑，将PVC防水卷材用于屋面变形缝防水优势明显，但是实际施工过程中会发现，由于PVC防水卷材与混凝土的粘结不牢，施工一段时间之后，PVC防水卷材与变形缝两侧混凝土墙体的连接容易开缝，甚至大片脱落，这就导致防水卷材失去作用，变形缝漏水。
发明内容
本发明的目的在于提供一种环氧砂浆及其制备方法和应用，该环氧砂浆可粘合混凝土和PVC防水卷材。
为实现上述目的，本发明提供一种环氧砂浆，其由环氧树脂和砂浆混合而成；
所述砂浆包含：18～25重量份硅酸盐水泥，60～70重量份细沙，0～5重量份熟石灰，0.1～0.2重量份疏水剂，0.03～0.05重量份引气剂，以及一定量的清水。
优选的，所述砂浆还包含0.5～2重量份聚醋酸乙烯共聚胶粉。
优选的，所述砂浆还包含适量的KFA。
优选的，所述环氧砂浆与砂浆的质量比为3:4～4:3。
优选的，所述砂浆的粒径不大于1mm。
本发明还提供上述环氧砂浆的制备方法，包括如下步骤：
1）将18～25重量份硅酸盐水泥、60～70重量份细沙、0～5重量份熟石灰、0.1～0.2重量份疏水剂、0.03～0.05重量份引气剂以及一定量的清水投入混合机中混合均匀，制得砂浆；
2）将环氧树脂和砂浆混合均匀，制得环氧砂浆；环氧砂浆与砂浆的质量比为3:4～4:3。
优选的，步骤1）中还投入0.5～2重量份聚醋酸乙烯共聚胶粉。
优选的，步骤1）中还投入适量的KFA。
优选的，本发明还提供上述环氧砂浆的应用，在混凝土上涂覆一层环氧砂浆，再在环氧砂浆上覆盖PVC防水卷材，通过环氧砂浆粘合混凝土和PVC防水卷材。
本发明的优点和有益效果在于：提供一种环氧砂浆及其制备方法和应用，该环氧砂浆可粘合混凝土和PVC防水卷材。
环氧砂浆由环氧树脂与砂浆混合而成，砂浆与混凝土粘附性强，环氧树脂与PVC防水卷材粘附性强，故环氧砂浆能够粘合混凝土和PVC防水卷材，可将PVC防水卷材与混凝土墙体粘粘在一起，避免两者直接粘粘不牢的问题。PVC防水卷材与混凝土墙体粘合牢固，不会在施工一端时间之后发生防水卷材开缝或脱节的情况，防水效果长期可靠。
具体实施方式
下面结合实施例，对本发明的具体实施方式作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
本发明提供一种环氧砂浆，其通过如下步骤制备：
1）将18～25重量份硅酸盐水泥、60～70重量份细沙、0～5重量份熟石灰、0.1～0.2重量份疏水剂、0.03～0.05重量份引气剂以及一定量的清水投入混合机中混合均匀，制得砂浆；优选的，所述砂浆的粒径不大于1mm；
2）将环氧树脂和砂浆混合均匀，制得环氧砂浆；环氧砂浆与砂浆的质量比为3:4～4:3。
优选的，步骤1）中还投入0.5～2重量份聚醋酸乙烯共聚胶粉。
优选的，步骤1）中还投入适量的KFA。
本发明还提供上述环氧砂浆的应用，在混凝土上涂覆一层环氧砂浆，再在环氧砂浆上覆盖PVC防水卷材，通过环氧砂浆粘合混凝土和PVC防水卷材。
环氧树脂与砂浆的质量比优选1:1，对于所处环境较潮湿的地方，该比例可以调整为1.2:1，对于所处环境较干燥的地方，该比例可以调整为1:1.2，这些数值只是建议值，具体的操作配比可根据施工实际情况进行调整。
环氧砂浆由环氧树脂与砂浆混合而成，砂浆与混凝土粘附性强，环氧树脂与PVC防水卷材粘附性强，故环氧砂浆能够粘合混凝土和PVC防水卷材，可将PVC防水卷材与混凝土墙体粘粘在一起，避免两者直接粘粘不牢的问题。PVC防水卷材与混凝土墙体粘合牢固，不会在施工一端时间之后发生防水卷材开缝或脱节的情况，防水效果长期可靠。
环氧砂浆和PVC防水卷材这两者的粘接质量是影响变形缝防水质量的主要因素，按照GB/T 22374-2018《地坪涂装材料》中6.3.1.2.3要求进行拉伸粘结强度试件的制备，然后按该标准的6.3.9的要求进行标准状态和浸水后拉伸强度的测试。经测试，本发明的环氧砂浆和PVC防水卷材这两者的拉伸粘结强度≥2.0Mpa，满足标准要求。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
