Abstract

本发明涉及一种生态长效重防腐涂料技术。该发明通过采用独创的无溶剂改性环氧技术，选用亲水高性能重防腐环氧树脂和经过特殊改性的颜料和填料，加入专有助剂，制造出能在水下、在100％潮湿钢结构和混凝土表面带锈涂装的长效重防腐涂料，满足恶劣腐蚀环境下长效重防腐的需要，解决传统防腐涂料不能解决的技术难题。

Description

重防腐涂料
本发明涉及一种长效重防腐环保涂料，特别是一种能在水下、在100％潮湿混凝土表面和钢结构表面带锈涂装的长效重防腐涂料。
目前，传统的防腐涂料，如环氧树脂系列存在着易脆的致命缺陷，酚醛树脂系列涂料中的羟基易和介质中的碱起反应发生作用，氯磺化聚烯涂料附着力不够、易起层、脱落，呋喃类等涂料普遍存在着固体含量低，溶剂含量高，成膜薄，附着力低，表面处理要求严格，施工工艺复杂，有露点限制、环境污染严重以及防腐寿命短等缺点，尤其是对金属表面要进行严格的喷砂除锈达到Sa2.5级，同时要求被涂装表面干燥，工序繁复而费用昂贵。而且根本不能在水下涂刷、水下固化。
本发明的目的就是要克服以往涂料不环保，表面处理要求高，附着力不强等缺陷.研制了一种能在水下、100％潮湿混凝土表面和潮湿钢结构表面带锈涂装的长效重防腐环保涂料。现在本发明不但能对本体做到低表面处理，而且还有很高的(17PMa/cm2)附着力。
本发明的技术方案：其特征在于不添加溶剂由下列成分按下列重量百分比组成：
无溶剂(无毒)改性树脂+填料+助剂
改性无苯环氧树脂            42-45
T31型阴阳离子交换脂         8-10
2500目JS滑石粉              9-11
2000目UV石英粉              13-15
GE钛白粉                    5-7
SPA-1消泡剂                 2-3.5
附着力促进剂                4-6
VG表面控制助剂              2.5-4
成膜抗藻剂                  2-3.5
醋酸丁酸纤维素              1.5-2.3
纯聚四氟抗湿剂              2-2.5
本发明的优越性在于无溶剂，充分利用阴阳离子交换脂，具有疏水功能，解决了以往涂料不环保，附着力不强等缺陷.现在本发明不但能快速在水下固化，而且还有很高的(17PMa/cm2)附着力。
实施例1：
改性无苯环氧树脂            43.8
T31型阴阳离子交换脂         9.0
2500目JS滑石粉              10.1
2000目UV石英粉              14.0
GE钛白粉                    6.0
SPA-1消泡剂                 3.0
RU附着力促进剂              5.0
VG表面控制助剂              3.4
成膜抗藻剂                  1.8
醋酸丁酸纤维素              1.6
纯聚四氟抗湿剂              2.3
其中改性无苯环氧树脂加T31型阴阳离子交换脂占51.8％，填料占30.1％，助剂占18.1％，颜料为氧化物颜料或钛白粉，以上原料均为国外进口，各自按比例混合、反应、搅拌、不添加溶剂就能得到重防腐环保涂料。
经过检测，资料如下：
涂膜外观：自流平好、色泽均匀；固体含量100％(无溶剂)；干燥时间：表干5小时、实干10小时；黏度KU148；柔韧性1MM；抗冲击强度50KG。CM；附着力17PMa/cm2；分别耐盐水性(6％NACL溶液)、耐盐雾试验、耐碱性(10％NAOH溶液)、耐酸性(0.3HCL溶液)，5000小时无变化。经检测，可以涂刷饮用水箱，属无毒型涂料。
实施例2：
改性无苯环氧树脂                    43.8
T31型阴阳离子交换脂                 9.0
2500目JS滑石粉                      10.1
2000目UV石英粉                      13.2
GE钛白粉                            6.0
SPA-1消泡剂                         3.2
RU附着力促进剂                      5.4
VG表面控制助剂                      3.4
成膜抗藻剂                          1.8
醋酸丁酸纤维素                      1.6
纯聚四氟抗湿剂                      2.5
余皆同实施例2。
