Description

椰油酰基谷氨酸三乙醇胺盐气相防锈母粒及其制备方法和应用 Cocoyl glutamate triethanolamine salts and VCI masterbatch preparation and application

技术领域: FIELD:

[0001] 本发明涉及适应多种金属制品无毒气相防锈塑料制品领域,具体地指一种椰油酰基谷氨酸三乙醇胺盐气相防锈母粒及其制备方法和具体应用。 [0001] The present invention relates to a Cocoyl glutamate triethanolamine salts VCI masterbatch preparation and the particular application and adapt to a variety of metal products, non-toxic VCI field of plastic products, in particular finger.

背景技术: Background technique:

[0002] 金属锈蚀是涉及国民经济各个领域的普遍问题,它是由于氧和水作用于金属表面生成氧化物和氢氧化物混合物的电化学过程,对金属及其制品的性能和价值有极大危害, 严重时会造成重大事故致使设备报废。 [0002] corrosion of metals is a common problem relates to various fields of national economy, it is due to the action of water and oxygen to form oxides and hydroxides of electrochemical processes on the metal surface of the mixture, and the performance of great value of the metal and its products harm, will cause a major accident resulting in serious equipment scrapped. 金属及其制品在生产、运输和贮存过程中,尤其是在海上运输和高热潮湿的陆路运输过程中,不可避免地会遭遇腐蚀而发生锈蚀。 Metals and their products in the production, transportation and storage, especially in humid heat of sea and land transportation during transport, will inevitably encounter the occurrence of rust corrosion. 据统计,2005 年我国全年因锈蚀而造成的经济损失在360亿元以上,其危害非常严重。 According to statistics, in 2005 China's annual corrosion caused economic losses of 360 billion yuan, the harm is very serious. 目前常用的涂抹防锈油脂法属于接触性防锈,不仅工艺繁琐、耗时费事、效果不佳,而且还需要在启封前进行脱脂清洗工序,极易造成环境的二次污染,而且对于那些接触不到防锈油的拐角、缝隙部位,则不能形成有效的防锈保护,此法已越来越不能被人们所接受。 The most commonly used method belongs to apply anti-rust oil rust contact, not only the process cumbersome, time consuming cumbersome, ineffective, but also the need for degreasing and cleaning prior to the unsealing step, easily cause secondary pollution of the environment, and those for the contact less rust preventive oil corner, a slit portion, can not form an effective corrosion protection, this method has not been more and more accepted. 采用真空包装方法则成本较高,且对于大型工件来说非常难于现实。 Vacuum packaging method is costly and very difficult for large workpieces reality. 干燥剂防锈虽然成本较低,使用方便,但受环境影响较大,效果很难保证。 Desiccant rust although low cost, easy to use, but influenced by the environment, the effect is difficult to guarantee.

[0003] 气相防锈技术(即VCI技术,VCI是英文Volatile Corrosion Inhibitor的缩写)是目前非接触性防锈的重要方法之一。 [0003] Technical VCI (VCI technology i.e., VCI is the abbreviation of Volatile Corrosion Inhibitor) is an important method for non-contact current rust. 它利用气相缓蚀剂在常温下自动挥发出气体在金属表面形成一层保护膜,抑制了电化学反应的发生,同时还阻挡了一些加速金属腐蚀物质对金属表面的侵蚀,从而减缓或阻止对金属表面锈蚀。 It uses VPI automatically volatilized gases formed in the metal layer of the surface protective film at normal temperature, the electrochemical reaction is suppressed, and also blocks some acceleration from metal corrosion attack on the metal surface, thereby slowing or stopping of corrosion of metal surfaces. 气相防锈技术具有环境友好、使用方便、 清洁干净等特点,近年来已在金属及其制品生产、运输和贮存等环节的防锈蚀中得到了广泛的应用。 VCI technology environmentally friendly, easy to use, clean, etc., in recent years, it has been widely used in anti-corrosion metal products and their production, transportation and storage of such links. 国内基于气相防锈技术开发的气相防锈产品也常有报道,特别是以塑料为气相防锈剂的载体而生产的气相防锈薄膜,具有透明、柔韧、可加工成型、阻隔性高等特点。 Domestic technical development based on VCI VCI products also often reported, particularly in the plastic carrier agent produced VCI VCI film with a transparent, flexibility, molding processability, and high barrier properties. 但是目前常用的气相防锈薄膜有吹膜型和涂覆型,但它们均存在缺陷,前者如CN01128198.7、 CN01127534.0公开的气相防锈薄膜中,气相缓蚀剂组分中均含有国际上禁用的强致癌物亚硝酸盐,而且CN01127534.0公开的工艺中将气相缓蚀剂直接加入到树脂中吹膜,由于没有进行混炼预处理,气相缓蚀剂颗粒分布不均匀,所得膜制品会出现表面粗糙和析霜现象;后者则以塑料膜为基材,将缓蚀剂和粘接剂混合后涂布于塑料薄膜上,这不仅能耗大,工序复杂,更不能清洁生产,还容易因混合不均匀而影响防锈效果,该种工艺所得的防锈薄膜仅对黑色金属有防锈作用,而对有色或多金属组合件缺少甚至没有保护功能。 But the most commonly used type VCI film and blown film coating type, but they have defects, such as the former CN01128198.7, CN01127534.0 VCI film disclosed in vapor phase corrosion inhibitor component contain International disabled on the strong carcinogen nitrite, and CN01127534.0 process disclosed in the vapor phase inhibitor is added directly to the resin blown film, since there is no pre-kneaded, vapor phase corrosion inhibitor particles unevenly distributed, the resulting film article surface roughening occurs and blooming analysis; the latter to a plastic film as the substrate, the inhibitor, and mixed adhesive is applied on a plastic film, which is not only energy consumption, the process is complicated, not clean production , due to uneven mixing but also easy to affect the rust, the rust-preventive film process resulting species only have ferrous metal rust prevention effect, while the lack of non-ferrous metal assembly or even no protection.

[0004] 由此可以看出,研制生产一种对多种多金属都具有优良防锈效果,而且兼具有环境友好、操作简便、外观漂亮的气相防锈薄膜,对解决涉及国民经济的金属锈蚀问题显得尤为迫切,而开发优质高效的气相防锈母粒则是实现这一需要最根本的途径和关键所在。 [0004] It can be seen, a variety of research to produce a plurality of metal having an excellent anti-corrosion effect, and environmentally-friendly and easy to operate, beautiful appearance VCI films, metal directed to solving the national economy corrosion problem is particularly urgent, and the development of high-quality and efficient VCI masterbatch is needed to achieve this most fundamental way and key.

[0005] -般认为有机羧酸及衍生物中含有极性的-C00H和-C0NH-等基团,与金属有一定的亲和力,容易在金属表面产生吸附,从而起到一定的防锈效果,其中有机羧酸醇胺盐结构就能满足这一要求。 [0005] - as that contained in the organic carboxylic acids and derivatives -C0NH- polar -C00H and like groups, and have a certain affinity for the metal, prone to adsorb on the metal surface, and thus play a rust-proof effect, wherein the organic carboxylic acid salt of an alcohol amine structure can meet this requirement. 因为当羧酸与醇胺混合后,体系中同时具有强极性的-C00H和-C0NH-基团,这些极性基团上的N和0原子上的孤对电子与Fe原子上的空d轨道形成配位键,在金属表面作定向排列。 Because when the mixed carboxylic acid with an alcohol amine, the system also has strong polarity and -C0NH- -C00H groups, N, and 0 atom lone polar groups on those of the Fe atoms on the electronic space d track-forming coordination bonds, for alignment on the metal surface. 而较长的非极性基团则定向排列于金属的外表面,一方面阻碍了铁的离子化,使金属表面水分子中的电子减少,另一方面阻碍了氢离子向金属表面扩散而抑制了阴极的还原反应,因此阻碍了阳极金属的腐蚀,是性能优良的缓蚀剂。 While the longer non-polar groups are aligned on the outer surface of the metal, on the one hand hindering the ferric ion, the metal surface of the water molecules in the electron reduction, hydrogen on the other hand hinders the diffusion of ions to the surface of the metal is suppressed a reduction reaction of the cathode, thus preventing the corrosion of the anode metal, is excellent in corrosion performance.

[0006] 硼酸由于每个硼原子以SP2杂化与氧原子结合,硼仍是缺电子,很容易与有机醇类化合物反应生成硼酸硼酸单酯、双酯、三酯及四取代螺环结构。 [0006] Since each of boronic acid bound to the boron atom and an oxygen atom SP2 hybridized, electron-deficient boron remains readily reacted with an organic alcohol compound of boronic acid monoester, diester, triester, and tetra-substituted spiro ring structure. 硼酸酯具有良好的润滑、防锈、杀菌等性能,而且对人体无毒害作用。 Boronate good lubrication, rust prevention, sterilization and other properties, but the human body without toxic effects. 但就目前来看,作为一种理想的绿色环保型添加剂,硼酸酯主要应用在水基切削液领域(李玮,马涛,王森,谭海林.硼酸酯在水基切削液中的应用.工具技术,2010,44(5): 93-95 .),分别起到极压润滑剂、表面活性剂、防锈剂、防腐杀菌剂的作用,而它们作为添加剂在气相防锈技术方面还未见涉及,尤其还未见有关以无毒的无机盐、羧酸醇胺盐、有机胺硼酸酯为复配缓蚀剂的气相防锈母粒及其制备方法和应用方面的报道。 But now, as an ideal green additives, application in the field of the main application boronate aqueous cutting liquid (Li Wei, Ma Tao, Sen, Tan Hailin boronate in aqueous cutting liquid tool technology, 2010,44 (5): 93-95), respectively, function as extreme pressure lubricants, surfactants, rust inhibitors, antiseptic, and also their use as an additive in technical VCI no it relates, in particular, has not been VCI masterbatch preparation method and application of reports of non-toxic inorganic salts, alkanolamine salts of carboxylic acids, organic amine boronic acid ester compound as corrosion inhibitor.
