Description

一种三组份蚀刻底漆涂料及制备方法
技术领域
本发明涉及轨道车辆用涂料领域，特别涉及一种三组份蚀刻底漆涂料及制备方法。
背景技术
铝合金以其低密度、高强度、高刚度、易于加工等优点广泛应用于轨道交通车辆的制造中，如果铝合金不经打磨直接喷漆，一般需要在铝合金上喷涂磷化底漆，由于磷化底漆中使用了四盐基锌黄，这是一种6价铬，有致癌作用，所以并不环保。
发明内容
为解决上述技术问题，本发明提供一种环保的三组份蚀刻底漆涂料及制备方法。
本发明的技术方案为：一种三组份蚀刻底漆涂料，包括涂料一、涂料二和涂料三，涂料一包括环氧改性羟基丙烯酸树脂、有机黄颜料、磷酸锌、环保防锈颜料、有机膨润土、硫酸钡、二甲苯、丁酯、分散剂、消泡剂、8900防流挂助剂，涂料二包括3390三聚体固化剂、二甲苯、丁酯，涂料三包括伯氨基硅烷偶联剂。
进一步的，涂料一、涂料二、涂料三的质量比为4：1：0.3～0.5。
进一步的，涂料一各组份的质量份数为环氧改性羟基丙烯酸树脂30～50份、有机黄颜料3～5份、磷酸锌3～7份、环保防锈颜料5～9份、有机膨润土0.3～0.5份、硫酸钡16～20份、二甲苯13～20份、丁酯3～7份、分散剂0.5～1份、消泡剂0.1～0.3份、8900防流挂助剂0.8～1.2份。
进一步的，涂料二各组份的质量份数为3390三聚体固化剂30～50份、二甲苯40～60份、丁酯5～15份。
进一步的，涂料一各组份的质量份数为环氧改性羟基丙烯酸树脂40份、有机黄颜料4份、磷酸锌5份、环保防锈颜料7份、有机膨润土0.4份、硫酸钡18份、二甲苯16.5份、丁酯5份、分散剂0.75份、消泡剂0.2份、8900防流挂助剂1份。
进一步的，涂料二各组份的质量份数为3390三聚体固化剂40份、二甲苯50份、丁酯10份。
进一步的，伯氨基硅烷偶联剂结构为Y-R-SiX3，X为乙氧基，Y为伯氨基。
进一步的，包括一种三组份蚀刻底漆涂料的制备方法，包括以下步骤：
(1)涂料一制备
Ⅰ、环氧改性羟基丙烯酸树脂加入投料罐中，加入部分二甲苯、丁酯搅匀，后依次加入分散剂、有机膨润土、有机黄颜料、磷酸锌、环保防锈颜料、硫酸钡，搅拌30min；Ⅱ、进入砂磨机进行研磨，研磨细度≤30um；Ⅲ、进入调漆工艺，加入8900防流挂助剂，高速搅拌40min完全分散后，降低搅拌速度加入消泡剂，用剩余二甲苯、丁醇来调整粘度，过滤包装；
(2)涂料二制备
在3390三聚体固化剂中搅拌加入二甲苯、丁酯，化匀过滤包装。
进一步的，步骤Ⅲ中高速搅拌速度为1500rpm/min。
本发明的原理：
环氧改性羟基丙烯酸树脂是在环氧树脂分子链的两端引入羟基丙烯酸，其中羟基与3390三聚体固化剂的异氰酸根反应，三聚体具有脂环结构，与含羟基的树脂交联后可形成空间网状结构；同时硅烷偶联剂中的伯氨基与丙烯酸树脂中的环氧基、羟基、3390三聚体固化剂的异氰酸根也进行反应，使硅烷偶联剂弥散在网状结构中；铝合金底材的亲水极性表面在环境中易吸附上一层水膜，如果为一般涂料，涂料内的大部分疏水基料很难对底材润湿，然而本发明由于硅烷偶联剂中的乙氧基存在，与水膜进行反应后生成乙醇和硅羟基(Si-OH)基团，从而使涂层与铝合金底材通过相当于化学键结合，提高涂料涂层的附着力。使整个涂层牢固的附着在铝合金表面。而且，环氧改性羟基丙烯酸树脂经过环氧的改性，分子链上有醚键(-C-O-C-)赋予其耐化学腐蚀性能，羟基(-OH)是极性基团，有助于提高附着力。
本发明的有益效果：
本发明三组份蚀刻底漆涂料中的涂料一、涂料二、涂料三在施工时混合，涂覆在轨道车辆的铝合金底材上，不需要对铝合金表面进行涂覆前的打磨，不需要喷涂磷化底漆，安全环保，省时省力。本发明具有潜在的市场价值。

涂料三在使用时与涂料一、涂料二混合，搅拌均匀、进行涂覆即可。涂料三伯氨基硅烷偶联剂为现有硅烷偶联剂中一种结构，制备方法可以使用现有技术中的方法，在此不再赘述。
实施例2
实施例2与实施例1基本相同，所不同的是涂料一各组份的质量份数为环氧改性羟基丙烯酸树脂40份、有机黄颜料4份、磷酸锌5份、环保防锈颜料7份、有机膨润土0.4份、硫酸钡18份、二甲苯16.5份、丁酯5份、分散剂0.75份、消泡剂0.2份、8900防流挂助剂1份。
实施例3
实施例3与实施例1基本相同，所不同的是涂料一各组份的质量份数为环氧改性羟基丙烯酸树脂50份、有机黄颜料5份、磷酸锌7份、环保防锈颜料9份、有机膨润土0.5份、硫酸钡20份、二甲苯20份、丁酯7份、分散剂1份、消泡剂0.3份、8900防流挂助剂1.2份。
实施例4
实施例5与实施例1基本相同，所不同的是涂料一、涂料二、涂料三的质量比为4：1：0.4。
实施例5
实施例5与实施例1基本相同，所不同的是涂料一、涂料二、涂料三的质量比为4：1：0.5。
对比例1
对比例1与实施例2基本相同，所不同的是用缩二脲N75固化剂代替3390三聚体固化剂。
对比例2
对比例2与实施例2基本相同，所不同的是用羟基丙烯酸树脂替换环氧改性羟基丙烯酸树脂。
对比例3
对比例3为市场上常用的磷化底漆。
对比实验
按表1对实施例1-5、对比例1-3进行试验，表1为各试验方法及指标情况表。表2为实施例1-5、对比例1-3试验结果表。
表1为各试验方法及指标情况表
项目 指标 检测方法
表干(min) ≤15 GB/T1728-1989
实干(h) ≤4 GB/T1728-1989
附着力(划格法)(级) ≤2 GB/T9286-1998
表2为各试验结果表
Figure BDA0002459751030000051
由表2可以看出，实施例1-5的表干、实干时间较对比例1-3快，对铝合金表面的附着力也较对比例1-3好，对比例1由于固化剂更换为缩二脲N75固化剂，对比例2由于羟基丙烯酸树脂没有经过环氧改性，表干、实干时间较长，对铝合金的附着力也较弱，对比例3表干、实干时间与附着力均不及实施例1-5，同时因含有6价铬致癌物，达不到环保要求。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础；当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
