本发明涉及一种环保重防腐涂料及制备方法，属于防腐蚀涂料领域。The invention relates to an environment-friendly heavy-duty anti-corrosion coating and a preparation method thereof, belonging to the field of anti-corrosion coatings.
背景技术Background technique
金属腐蚀是一种非常普遍的现象，而腐蚀很少是因单纯的机械或者物理因素所引起，大部分的损坏都与其周边环境有着密切的关系。金属的腐蚀存在于国民经济和国防建设的各个领域，不仅对国民经济以及国防建设中的设施造成极大的损害，而且金属腐蚀中的应力腐蚀和腐蚀疲劳所造成的事故会危害人身安全。金属腐蚀造成了大量的能源资源浪费和环境污染。Metal corrosion is a very common phenomenon, and corrosion is rarely caused by purely mechanical or physical factors, and most of the damage is closely related to its surrounding environment. Metal corrosion exists in various fields of national economy and national defense construction, not only causing great damage to national economy and national defense construction facilities, but also accidents caused by stress corrosion and corrosion fatigue in metal corrosion will endanger personal safety. Metal corrosion has caused a lot of waste of energy resources and environmental pollution.
使用涂层对金属进行保护是最实用，经济，有效的方法。因此对防腐涂料的研究一直是金属保护和涂料行业的重要课题。传统的金属防腐蚀涂料几乎均为溶剂型涂料，在成膜过程中伴随有大量的溶剂挥发。挥发的溶剂不仅对人体以及周边的环境造成危害和污染，同时也造成了资源的浪费。而且传统防腐涂料中所添加的防锈颜料都含有铅、铬等有害物质，同样对人体和环境造成危害。随着对环境要求的不断提高，环保意识的不断加强以及法律法规对环境污染的严格控制，目前迫切需要环境友好型的涂料。因此对环保型的防腐涂料的呼声日益明显。The use of coatings to protect metals is the most practical, economical and effective method. Therefore, the research on anti-corrosion coatings has always been an important topic in metal protection and coatings industry. Traditional metal anti-corrosion coatings are almost all solvent-based coatings, which are accompanied by a large amount of solvent volatilization during the film formation process. Volatile solvents not only cause harm and pollution to the human body and the surrounding environment, but also cause a waste of resources. Moreover, the anti-rust pigments added in traditional anti-corrosion coatings all contain harmful substances such as lead and chromium, which are also harmful to the human body and the environment. With the continuous improvement of environmental requirements, the continuous strengthening of environmental protection awareness and the strict control of environmental pollution by laws and regulations, there is an urgent need for environmentally friendly coatings. Therefore, the voice of the environment-friendly anticorrosion coating is becoming more and more obvious.
为减少对环境的污染，目前对环保型涂料的研究集中在水性涂料和低溶剂型涂料。环氧树脂涂料是目前应用前景最大的环保型涂料。除却涂料本身，防锈颜料的选择及使用也是决定涂料性能优劣的一个非常重要的因素。为了替代传统的铬黄，红丹等有毒颜料，人们研究了如磷酸锌，三聚磷酸铝，以及鳞片类的防锈颜料，如中国专利文献CN102382494A（申请号：201110226841.0）公开的玻璃鳞片防腐涂料，但是这些防锈颜料存在成本高，分散性不好，比重大等缺点。聚苯胺在防腐涂料中具有出非常优异的性能，如中国专利文献CN102634276A（申请号：201210125211.9）公开的一种聚苯胺防腐涂料及其制备方法，该防腐涂料使用了聚苯胺改性的蒙脱土复合填料，起到了良好的防腐效果，但是蒙脱土本身的防腐效果并不佳，而且改性过程繁琐。In order to reduce environmental pollution, the current research on environmentally friendly coatings focuses on water-based coatings and low-solvent coatings. Epoxy resin coatings are currently the most environmentally friendly coatings with the greatest application prospects. In addition to the paint itself, the selection and use of anti-rust pigments are also a very important factor in determining the performance of the paint. In order to replace the traditional toxic pigments such as chrome yellow and red lead, people have studied anti-rust pigments such as zinc phosphate, aluminum tripolyphosphate, and scales, such as the glass flake anti-corrosion coating disclosed in Chinese patent document CN102382494A (application number: 201110226841.0) , but these anti-rust pigments have the disadvantages of high cost, poor dispersibility, and large specific weight. Polyaniline has very excellent properties in anti-corrosion coatings, such as a polyaniline anti-corrosion coating and its preparation method disclosed in Chinese patent document CN102634276A (application number: 201210125211.9). The anti-corrosion coating uses polyaniline-modified montmorillonite The composite filler has a good anti-corrosion effect, but the anti-corrosion effect of montmorillonite itself is not good, and the modification process is cumbersome.
