一种复合导电体导静电涂料及其制备方法 A composite conductor conducting electrostatic coating and preparation method

技术领域 FIELD

:本发明涉及一种涂料及其制备方法,属于一种复合导电体导静电涂料及其制备方法。 : The present invention relates to a coating method for its preparation, it belongs to a conductor conducting electrostatic coating and preparation method thereof.

背景技术 Background technique

:导静电涂料是一种应用范围十分广泛的涂料,可以导出材料表面积累的静电荷,消除静电。 : Static conductive coating is a wide range of applications of paint, you can export the material surface accumulation of static charge, to eliminate static electricity. 在石油产品的储运过程中,防静电是一个特别值得注意的问题,导静电涂料是防静电的有效措施。 In the storage and transportation of petroleum products, the anti-static is a problem particularly noteworthy, static conductive coatings are effective measures to prevent static electricity. 国家技术监督局早在1992年1月发布的强制性国家标准GB13348-92,规定“储罐内壁应使用防静电腐蚀涂料,涂料体电阻率低于109Ω·cm,面电阻率低于108Ω·cm。1997年7月又发布国家标准GB16906-1997《石油罐导静电涂料电阻率测定法》,对石油产品储罐防静电防腐蚀涂料做出油漆材料电阻率及施工验收的规范。2001年9月又出台了“轻质油品安全静止电导率”国家标准,编号为GB6590-2001,系列标准的实施,有效预防了由静电引发的火灾和爆炸灾害。 Bureau of Technical Supervision as early as January 1992 issued a mandatory national standard GB13348-92, the provisions "should use anti-static tank wall corrosion coatings, paints a volume resistivity of less than 109Ω · cm, surface resistivity less than 108Ω · cm . in July 1997 he released the national standard GB16906-1997 "oil tank guided electrostatic paint resistivity measurement method" to make paint resistivity specification and construction inspection of material storage tanks for petroleum products, anti-static anti-corrosion coatings. September 2001 also issued a "safety rest conductivity of light oil," the national standard, numbered for the implementation of GB6590-2001, series of standards, the effective prevention of fire and explosion hazards caused by static electricity.

目前使用的储油罐,主要是以金属、碳黑或金属氧化物为导电功能体的电静电涂料,其综合性能并不理想,如污染油品、附着力和防腐性能较差及使用寿命短等缺点,无法达到国家新颁布的技术标准。 Storage tanks currently used, mainly Electrostatic coating of metal, carbon black or conductive metal oxide is functional body, its overall performance is not ideal, such as oil contamination, poor adhesion and corrosion resistance and short service life and other shortcomings, the country can not meet the new standards promulgated.

第一代储没罐用的导静电涂料采用金属或石墨为导电功能体,金属易被氧化,容易失去导静电的功能,现已不使用,而石墨导电功能体的加入量必须在15%-20%以上,虽然具有了导静电的功能,但导静电涂料的其它性能受到了严重影响,更为严重的是,由于石墨的加入量多,油品很容易将石墨从涂层中抽提出来,悬浮于油品中的石墨不易分离,将严重影响油品的质量。 The first generation storage tank not conducting electrostatic coating with a metal or graphite as a conductive functional material, a metal susceptible to oxidation, it is easy to lose conductivity static function, which is no longer used, and the added amount of the graphite conductive material must function at 15% - more than 20%, while having a static conductive features, but other performance static conductive coatings has been seriously affected, the more serious is that, due to the amount of graphite and more oil can easily be extracted from the graphite coating , graphite suspended in oil easily separated, will seriously affect the quality of the oil. 因此,以石墨为导电功能的导静电涂料已被石油化工行业建议不作为储油罐导静电涂料使用。 Therefore, the function of graphite as a conductive static conductive coating has been recommended that the petrochemical industry is not used as tank conducting electrostatic paint. 20世纪90年代出现的以SnO2/SbO2包覆的云母作为导电功能体,由于是氧化物,它克服了金属易氧化的缺点,且自身颜色浅,易于制备清一色或彩色导静电涂层,因此近年来发展较快,但它同存在加入量过大的问题,影响了涂料的其它性能,例如,其附着力和防腐性能就不能很好的满足储油罐对涂料的要求。 1990s appears to mica coated with SnO2 SbO2 / function as the conductive material, because it is an oxide which overcomes the disadvantages of the easily oxidized metal, and their light color, or a color easy to prepare all-static conductive coating, and therefore in recent years to develop faster, but it added same problem of excessive presence affects other properties of the coating, for example, the adhesion and corrosion resistance can not satisfy the requirements for tank coatings. 储油罐用导静电涂料要求在具有优良导静电性能的同时还应具有优良的防腐、防渗漏等功能,而目前使用的各种导静电涂料在实施过程中最突出的问题是抗静电性能不够持久,耐水性不好,普遍色黑,耐油防腐性能与抗静电性能不能兼顾,涂料的使用寿命短及填料污染油品。 Tanks used antistatic coatings having excellent corrosion is also required at the same time having excellent static conductive properties, anti-leakage functions, and various static conductive coatings currently used in the embodiment during the most prominent problem is antistatic properties not enough persistence, good water resistance, the general color black, oil and corrosion resistance and antistatic properties can not be taken into account, the short life of the coating and filling of oil pollution.
