一种金属清洗剂a metal cleaner

技术领域technical field

本发明涉及一种清洗剂，特别是一种用于金属表面清洗除油的清洗剂、其制备方法及其使用方法。The invention relates to a cleaning agent, in particular to a cleaning agent for cleaning and degreasing metal surfaces, its preparation method and its application method.

背景技术Background technique

金属零件的加工过程中，大多数都使用油性润滑剂和类似物质，在金属零件表面会留下油渍。金属零件在表面处理(如电镀、磷化处理、涂层处理等)之前或最终使用前，需要将这些油渍除去。随着中国制造业的快速发展，对清洗技术的要求越来越高，清洗剂的用量越来越大。因此，有许多关于清洗剂的研究和清洗剂产品。During the processing of metal parts, most of them use oil-based lubricants and similar substances, which will leave oil stains on the surface of metal parts. Metal parts need to remove these oil stains before surface treatment (such as electroplating, phosphating treatment, coating treatment, etc.) or before final use. With the rapid development of China's manufacturing industry, the requirements for cleaning technology are getting higher and higher, and the amount of cleaning agent is increasing. Therefore, there is a lot of research on cleaning agents and cleaning products.

CN 98112285A提供一种脱脂剂，由汽油、乙醇、苯和三氯乙烯经混合制成。脱脂效果好、脱脂速度快、可重复使用次数多。但是其使用了大量的有机物质，有毒，对环境和使用者的身体健康产生极大损害；且上述有机物质易燃，带来使用和存放上的安全隐患。CN 98112285A provides a kind of degreasing agent, is made by mixing gasoline, ethanol, benzene and trichlorethylene. The degreasing effect is good, the degreasing speed is fast, and it can be used repeatedly. However, it uses a large amount of organic substances, which are toxic and cause great damage to the environment and the health of users; and the above-mentioned organic substances are flammable, which brings safety hazards in use and storage.

CN 1908235A公开了一种脱脂剂，含有纯碱、三聚磷酸钠、焦磷酸钠、五水偏硅酸钠、硼砂、有机硅消泡剂、葡萄糖酸钠、乳化剂TX-10、乳化剂OS和乳化剂OP-10。用于钢板、铁皮、铝箔、铜材、铝合金等材料的脱脂解决现有脱脂剂存在脱脂效率低、对工件腐蚀性大等问题。但是上述脱脂剂含磷和TX-10。由于普遍认为含磷清洗剂的废液会使水生植物富营养化，部分地区已开始禁止使用含磷工业清洗剂。此外，对于一些对生态环境有害，即难以生物降解的表面活性剂也逐渐被淘汰，如用易生物降解的直链烷基苯磺酸代替难生物降解的支链烷基苯磺酸。一些发达国家已逐渐禁止使用TX-10(烷基酚聚氧乙烯醚)，因为烷基酚不降解，还会引起动物的雌性化。CN 1908235A discloses a degreasing agent containing soda ash, sodium tripolyphosphate, sodium pyrophosphate, sodium metasilicate pentahydrate, borax, organic silicon defoamer, sodium gluconate, emulsifier TX-10, emulsifier OS and Emulsifier OP-10. It is used for the degreasing of steel plates, iron sheets, aluminum foils, copper materials, aluminum alloys and other materials to solve the problems of low degreasing efficiency and high corrosion to workpieces in existing degreasing agents. But the above degreaser contains phosphorus and TX-10. Because it is generally believed that the waste liquid of phosphorus-containing cleaning agents will cause eutrophication of aquatic plants, some areas have begun to ban the use of phosphorus-containing industrial cleaning agents. In addition, for some surfactants that are harmful to the ecological environment, that is, difficult to biodegrade, they are gradually eliminated, such as replacing branched alkylbenzene sulfonic acids that are difficult to biodegrade with linear alkylbenzene sulfonic acids that are easily biodegradable. Some developed countries have gradually banned the use of TX-10 (alkylphenol ethoxylates), because alkylphenols do not degrade and can cause feminization of animals.

CN 1888040A提供一种不锈钢清洗用脱脂剂，含有磷酸，烷基苯磺酸钠，十二烷基苯磺酸钠，OP-10乳化剂，其余为水。清洗脱脂后表面有光泽不发乌，对不锈钢的表面无侵蚀作用；受酸碱、软硬水、海水的影响较小，去脂能力强，清洗效果好；无毒、不易燃，使用简单方便，可回收重复利用。但是其使用大量的磷酸会对金属产生腐蚀，并且磷的使用危害环境。CN 1888040A provides a kind of degreasing agent for cleaning stainless steel, containing phosphoric acid, sodium alkylbenzenesulfonate, sodium dodecylbenzenesulfonate, OP-10 emulsifier, and the rest are water. After cleaning and degreasing, the surface is shiny and not black, and has no corrosive effect on the surface of stainless steel; less affected by acid and alkali, soft and hard water, sea water, strong degreasing ability, and good cleaning effect; non-toxic, non-flammable, easy to use , can be recycled and reused. However, the use of a large amount of phosphoric acid can cause corrosion to metals, and the use of phosphorus is harmful to the environment.

CN 102021591A公开了一种钢铁表面酸性脱脂剂及配制方法。该酸性脱脂剂为聚氧乙烯辛烷基苯酚醚、椰子油烷基醇酰胺、平平加、聚氧乙烯脂肪醇醚硫化钠、磷酸、硝酸、氟化铵、六甲基四胺。该酸性脱脂剂与盐酸配合在常温下能达到除油酸洗一步完成。但是其使用大量的硝酸和磷酸会对金属产生腐蚀，并且磷的使用危害环境。CN 102021591A discloses an acidic degreasing agent for steel surfaces and a preparation method thereof. The acidic degreasing agent is polyoxyethylene octyl phenol ether, coconut oil alkyl alcohol amide, pingpinga, polyoxyethylene fatty alcohol ether sodium sulfide, phosphoric acid, nitric acid, ammonium fluoride, and hexamethyltetramine. The acidic degreasing agent can be combined with hydrochloric acid to achieve oil removal and pickling in one step at room temperature. However, the use of a large amount of nitric acid and phosphoric acid can cause corrosion to metals, and the use of phosphorus is harmful to the environment.

CN 101956200A公开一种脱脂效果好、易清洗、可满足后道工艺要求的无磷环保型粉状脱脂剂及制造方法，原料是氢氧化钾、碳酸钠、五水偏硅酸钠、代磷助剂、柠檬酸钠、亚硝酸钠、活性剂QYL-10F、活性剂AEO-9、渗透剂JF及消泡剂。CN 101736353A提供了一种金属表面脱脂剂，其要点是：5％-25％的常用碱，常用碱为氢氧化钠或氢氧化钾中的一种或一种以上；10％-15％的缓冲剂与助剂，缓冲剂与助剂为硅酸钠、三聚磷酸钠、焦磷酸钾的中一种或一种以上；3％-5％的表面活性剂，表面活性剂为BJJ001、BJJ003、AEC中的一种或一种以上；0.5％-1％的消泡剂和抑泡剂，消泡剂和抑泡剂为有机硅、磷酸酯中的一种或一种以上；余量的水。上述两篇文献均采用强碱清洗，会对金属进行腐蚀，且清洗效果较差。CN 101956200A discloses a phosphorus-free environmental protection powder degreasing agent with good degreasing effect, easy to clean, and can meet the requirements of subsequent processes, and its manufacturing method. The raw materials are potassium hydroxide, sodium carbonate, sodium metasilicate pentahydrate, phosphorus-substituted agent, sodium citrate, sodium nitrite, active agent QYL-10F, active agent AEO-9, penetrant JF and defoamer. CN 101736353A provides a metal surface degreasing agent, the main points of which are: 5%-25% common alkali, which is one or more of sodium hydroxide or potassium hydroxide; 10%-15% buffer The buffer and auxiliary agent are one or more of sodium silicate, sodium tripolyphosphate, potassium pyrophosphate; 3%-5% surfactant, the surfactant is BJJ001, BJJ003, One or more of AEC; 0.5%-1% of defoamer and antifoaming agent, defoaming agent and antifoaming agent are one or more of organosilicon and phosphate ester; the rest of water . Both of the above two documents use strong alkali cleaning, which will corrode the metal, and the cleaning effect is relatively poor.

因此现有技术中的清洗剂存在脱脂效果不理想、污染环境、危害使用者身体健康、腐蚀被清洗金属、使用存放不安全、适用金属范围不够广泛等各种缺陷，不能满足急速发展的生产需要。Therefore, the cleaning agent in the prior art has various defects such as unsatisfactory degreasing effect, polluting the environment, endangering the health of users, corroding the metal to be cleaned, unsafe use and storage, and insufficient range of applicable metals, etc., which cannot meet the rapidly developing production needs. .
