Description

一种水性环氧防腐防锈漆及其制备方法A kind of waterborne epoxy anticorrosion and antirust paint and preparation method thereof

技术领域technical field

本发明属于防锈漆技术领域，特别是涉及一种水性环氧防腐防锈漆及其制备方法。The invention belongs to the technical field of antirust paint, in particular to a water-based epoxy anticorrosion and antirust paint and a preparation method thereof.

背景技术Background technique

传统溶剂型防锈涂料主要是以有机溶剂为分散介质。因此，在制备及使用过程中会挥发大量的有机化合物即VolatileOrganicComposition(简称VOC)。VOC的挥发对生活环境以及人类的身体健康都是潜在的威胁。另一方面，原油的价格出现大幅度上涨，导致各地油性涂料的价格被迫不断提升，其原材料的成本也不断增加。因此，各国学者以及研究人员将研究重心逐渐由油性涂料转向水性涂料。Traditional solvent-based antirust coatings mainly use organic solvents as the dispersion medium. Therefore, a large amount of organic compounds, namely Volatile Organic Composition (VOC for short), will volatilize in the process of preparation and use. The volatilization of VOC is a potential threat to the living environment and human health. On the other hand, the price of crude oil has risen sharply, which has forced the price of oil-based paints to increase continuously, and the cost of raw materials has also continued to increase. Therefore, scholars and researchers from various countries have gradually shifted their research focus from oil-based paints to water-based paints.

水性涂料是以水作为溶剂(或者作为分散介质)的涂料，具有无毒、无味、价格低廉、原材料资源丰富等特点，可以大大减少原材料成本，以及对大气造成的污染；并且可极大地提高涂料在储存、运输和施工过程中的安全性。Water-based coatings use water as a solvent (or as a dispersion medium). They are non-toxic, tasteless, low in price, and rich in raw material resources, which can greatly reduce raw material costs and air pollution; and can greatly improve coating performance. Safety during storage, transportation and construction.

目前，国外一些公司在聚合物乳液合成上，采用无表面活性剂的自乳化技术，即用其它特定的聚合技术使多种不同单体组成的聚合物呈层状结构存在于同一胶粒中，从而达到调节玻璃化温度(Tg)，保证产品性能的目的，使产品既具有一定的硬度、耐污染性，又使施工易于进行。另外，通过定向聚合、辐射聚合、互穿网络聚合等制得聚合物乳液来改进涂料的性能和功能。At present, some foreign companies use self-emulsification technology without surfactants in the synthesis of polymer emulsions, that is, use other specific polymerization techniques to make polymers composed of various monomers exist in the same micelle in a layered structure. In order to achieve the purpose of adjusting the glass transition temperature (Tg) and ensuring the performance of the product, the product not only has a certain hardness and pollution resistance, but also makes the construction easy to carry out. In addition, polymer emulsions are prepared by directional polymerization, radiation polymerization, interpenetrating network polymerization, etc. to improve the performance and function of coatings.

而国内水性防腐涂料的发展方向主要为以下三个方面：(1)水性富锌底漆：无机富锌底漆和环氧富锌底漆是长效的底漆之一，但其均为溶剂型涂料。以高模数的改性硅酸盐为基料的水性无机富锌底漆已是经实践考验的高性能防腐防污涂料，具有较大的发展潜力；(2)研发有机改性的无机防腐材料：近年来，国外应用有机乳液改性混凝土，以改进其强度、耐介质性，广泛应用于工业地坪的涂装，其中环氧水乳液发展最快。近10年来，已开始应用于我国的防腐工程领域中，但研发工作不系统，未形成系列产品。(3)研发钢结构用水性防腐底漆和面漆：水性防腐底漆必须解决基材的“闪蚀”和耐水性差的难题；而对于面漆，主要是在保证其具有优良的保护性能的前提下，提高其装饰性和耐久性；同时，水性涂料对施工环境的依赖性更强，如何保证在高湿、低温及封闭环境下获得性能良好的涂层是水性防腐涂料未来需着重解决的问题。The development direction of domestic water-based anti-corrosion coatings is mainly in the following three aspects: (1) Water-based zinc-rich primer: inorganic zinc-rich primer and epoxy zinc-rich primer are one of the long-term primers, but they are all solvents type paint. The waterborne inorganic zinc-rich primer based on high-modulus modified silicate is a proven high-performance anti-corrosion and anti-fouling coating with great development potential; (2) research and development of organically modified inorganic anti-corrosion Materials: In recent years, organic emulsion modified concrete has been applied abroad to improve its strength and medium resistance, and it is widely used in the coating of industrial floors, among which epoxy water emulsion has the fastest development. In the past 10 years, it has been applied in the field of anti-corrosion engineering in my country, but the research and development work is not systematic, and no series of products have been formed. (3) Research and development of water-based anti-corrosion primers and topcoats for steel structures: Water-based anti-corrosion primers must solve the problems of "flash corrosion" and poor water resistance of the substrate; for topcoats, it is mainly to ensure that they have excellent protection properties At the same time, water-based coatings are more dependent on the construction environment. How to ensure a coating with good performance under high humidity, low temperature and closed environment is a key issue for water-based anti-corrosion coatings in the future. question.

因此，开发一种耐盐水性能好、附着力强、抗腐蚀能力强的水性涂料迫在眉睫。目前，据报道已知，磷酸锌是一种性能优良的新型无毒防锈颜料，被广泛应用于涂料工业制备各类防锈涂料及水剂涂料。磷酸与金属基底反应，生成不溶的三代磷酸盐，三代磷酸盐沉积在腐蚀位置上，把腐蚀区封住形成了隔离层，从而阻止了腐蚀的进一步发生。三聚磷酸铝是聚磷酸盐防锈颜料的典型代表，其可用于制备多种无污染、节能的无机高分子防锈、防腐蚀、耐高温的颜料和涂料。三聚磷酸根离子P3010 5-具有很好的化学活性，能与多种金属离子形成络合物，对二价、三价铁离子具有很强的络合能力，形成三聚磷酸铁保护膜。此外，三聚磷酸根P3010 5-发生解聚反应生成从焦磷酸根离子到正磷酸根离子，这些离子进一步在金属表面形成坚韧的钝化膜。经复合改性的磷酸系颜料能提高传统磷酸盐防锈颜料的防锈性能，产品耐盐水性变好。但是将水性磷酸锌与三聚磷酸铝复合使用作为防腐填料确鲜见报道。Therefore, it is imminent to develop a water-based coating with good salt water resistance, strong adhesion and strong corrosion resistance. At present, it is reported that zinc phosphate is a new type of non-toxic anti-rust pigment with excellent performance, which is widely used in the coating industry to prepare various anti-rust coatings and water-based coatings. Phosphoric acid reacts with the metal substrate to generate insoluble tertiary phosphate, which deposits on the corrosion site and seals the corrosion area to form an isolation layer, thereby preventing further corrosion. Aluminum tripolyphosphate is a typical representative of polyphosphate antirust pigments, which can be used to prepare various non-polluting, energy-saving inorganic polymer antirust, anticorrosion, high temperature resistant pigments and coatings. Tripolyphosphate ion P 3 0 10 5- has good chemical activity, can form complexes with various metal ions, and has strong complexation ability to divalent and ferric ions to form iron tripolyphosphate protective film. In addition, the depolymerization reaction of tripolyphosphate P 3 0 10 5- generates pyrophosphate ions to orthophosphate ions, and these ions further form a tough passivation film on the metal surface. The composite modified phosphoric acid pigment can improve the antirust performance of traditional phosphate antirust pigment, and the salt water resistance of the product becomes better. However, there are few reports on the combined use of water-based zinc phosphate and aluminum tripolyphosphate as anti-corrosion fillers.

本发明水性环氧防腐防锈漆的优点在于：The advantage of water-based epoxy anticorrosion antirust paint of the present invention is:

其绿色环保、原材料价格低廉，制备过程简单；同时，耐盐水性能优良、附着力强和抗闪锈效果良好。磷酸锌中的磷酸与金属基底反应，生成不溶的三代磷酸盐，三代磷酸盐沉积在腐蚀点上，把腐蚀区封住形成了隔离层，从而阻止了腐蚀的进一步发生。磷酸锌与基料中的羧基和羟基发生反应，生成络合物；而这种络合物能与腐蚀产物发生反应，在底材表面上形成紧密的保护膜，从而保护金属基底，不被腐蚀。三聚磷酸铝是聚磷酸盐防锈颜料的典型代表，其可用于制备多种无污染、节能的无机高分子防锈、防腐蚀、耐高温的颜料和涂料。三聚磷酸铝中的三聚磷酸根离子具有很好的化学活性，能与多种金属离子形成络合物，对二价、三价铁离子具有很强的络合能力，形成三聚磷酸铁保护膜。此外，三聚磷酸根P3010 5-发生解聚反应生成从焦磷酸根离子到正磷酸根离子，这些离子进一步在金属表面形成坚韧的钝化膜。改性三聚磷酸铝具有防锈力强、附着力高、白色、无毒等特点，原料易得，价格适宜，是铅、铬防锈颜料的替代品，因此受到各方面的注视。两者复合使用加上防腐填料金红石型钛白粉的共同作用可以使得防腐效果更佳显著。实际试验中也证实三者的复合使用比任一种单一使用的效果都要好。It is green and environment-friendly, has low raw material prices and simple preparation process; meanwhile, it has excellent salt water resistance, strong adhesion and good anti-flash rust effect. Phosphoric acid in zinc phosphate reacts with the metal substrate to generate insoluble tertiary phosphate, which deposits on the corrosion point and seals the corrosion area to form an isolation layer, thereby preventing further corrosion. Zinc phosphate reacts with carboxyl and hydroxyl groups in the base material to form a complex; and this complex can react with corrosion products to form a tight protective film on the surface of the substrate, thereby protecting the metal substrate from corrosion . Aluminum tripolyphosphate is a typical representative of polyphosphate antirust pigments, which can be used to prepare various non-polluting, energy-saving inorganic polymer antirust, anticorrosion, high temperature resistant pigments and coatings. The tripolyphosphate ion in aluminum tripolyphosphate has good chemical activity, can form complexes with various metal ions, and has a strong complexing ability for divalent and ferric ions, forming iron tripolyphosphate protective film. In addition, the depolymerization reaction of tripolyphosphate P 3 0 10 5- generates pyrophosphate ions to orthophosphate ions, and these ions further form a tough passivation film on the metal surface. Modified aluminum tripolyphosphate has the characteristics of strong rust resistance, high adhesion, white color, and non-toxicity. The raw materials are easily available and the price is reasonable. It is a substitute for lead and chromium anti-rust pigments, so it has attracted attention from all sides. The combined use of the two and the joint action of anti-corrosion filler rutile titanium dioxide can make the anti-corrosion effect better and more significant. The actual test also proved that the combined use of the three is better than any single use.
