技术领域technical field
本发明涉及一种研磨抛光浆料及不锈钢镜面板加工生产方法，属于金属板加工技术领域。The invention relates to a grinding and polishing slurry and a processing and production method for a stainless steel mirror panel, belonging to the technical field of metal plate processing.
背景技术Background technique
不锈钢镜面板加工生产传统工艺：材料选用粗糙度不高于Ra0.15μm和Ra0.07μm的优质不锈钢2B或BA表面的冷轧板，使用多磨头抛光研磨机，加入氧化铝微粉硝酸溶液研磨生产。这种加工工艺生产不锈钢镜面板，利用初磨、半精磨、精磨等多道工序进行抛光，使不锈钢表面粗糙度在0.01μm以下，反射率在64%以上，达到镜面技术指标要求。原抛光研磨机的精磨和半精磨段使用2%硝酸与3%氧化铝配成的传统的磨液工艺，因硝酸为强酸，生产过程中酸雾对研磨设备有较强的腐蚀，对人体呼吸道一定的伤害，不仅如此，生产废液中重金属铬、镍离子还需经污水处理站高成本处理后才能达标排放。The traditional process of stainless steel mirror panel processing and production: the material is made of high-quality stainless steel 2B or BA cold-rolled plate with a roughness not higher than Ra0.15μm and Ra0.07μm, using a multi-grinding head polishing and grinding machine, adding alumina micropowder nitric acid solution for grinding and production. This processing technology produces stainless steel mirror panels, which are polished by multiple processes such as primary grinding, semi-finishing, and fine grinding, so that the surface roughness of the stainless steel is below 0.01 μm, and the reflectivity is above 64%, which meets the technical requirements of mirror surface. The fine grinding and semi-fine grinding sections of the original polishing and grinding machine use the traditional grinding liquid process of 2% nitric acid and 3% alumina. Because nitric acid is a strong acid, the acid mist in the production process has strong corrosion on the grinding equipment, which is very harmful to the grinding equipment. Not only that, the heavy metal chromium and nickel ions in the production waste liquid need to be treated at a high cost by the sewage treatment station before they can reach the standard discharge.
发明内容SUMMARY OF THE INVENTION
发明目的：为了克服现有技术中存在的不足，本发明提供一种能够避免强硝酸的腐蚀破坏，同时环保的研磨抛光浆料及镜面板制备方法。Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a grinding and polishing slurry and a method for preparing a mirror panel that can avoid the corrosion damage of strong nitric acid and at the same time are environmentally friendly.
技术方案：为实现上述目的，本发明采用的技术方案为：Technical scheme: In order to realize the above-mentioned purpose, the technical scheme adopted in the present invention is:
一种镜面板制备方法，对不锈钢面板进行镜面抛光，研磨抛光机采用如下研磨抛光浆料，浆料的细度为1500目以上；由有机酸（包括柠檬酸、醋酸、草酸、苯甲酸、苹果酸、抗坏血酸、酒石酸等中的一种或者两种以上的混合物）替代无机强酸硝酸，添加有机酸使浆料的pH值为5.5-6.3，浆料中含有质量比为2.2±0.2%二氧化硅。A method for preparing a mirror panel, the stainless steel panel is mirror-polished, the grinding and polishing machine adopts the following grinding and polishing slurry, and the fineness of the slurry is more than 1500 mesh; acid, ascorbic acid, tartaric acid, etc. or a mixture of two or more) instead of strong inorganic acid nitric acid, adding organic acid to make the pH of the slurry 5.5-6.3, and the slurry contains 2.2±0.2% silica by mass .
因柠檬酸是一种重要的有机酸，用于食品添加剂，对金属表面也起清洁作用，可当金属清洗剂使用；二氧化硅是硅原子跟（四个）氧原子形成的球形结构的原子晶体，整个晶体又可以看作是一个巨大分子，是一种坚硬难溶的球形固体, 呈酸性氧化物，二氧化硅当中间载体，能磨削去除不锈钢表面凸处（也即磨削板表面不平处），再进行研磨抛光，完全能够使不锈钢表面达到镜面状态。精磨浆料的细度为2500目以上。Because citric acid is an important organic acid, it is used in food additives, and it also has a cleaning effect on metal surfaces. It can be used as a metal cleaning agent; silicon dioxide is an atom of a spherical structure formed by silicon atoms and (four) oxygen atoms. The crystal, the whole crystal can be regarded as a huge molecule, it is a kind of hard and insoluble spherical solid, which is an acidic oxide, and silica is used as an intermediate carrier, which can grind and remove the protrusions on the surface of stainless steel (that is, the surface of the grinding plate). unevenness), and then grinding and polishing, which can completely make the stainless steel surface reach a mirror state. The fineness of the refining slurry is 2500 mesh or more.
由有机酸、弱酸替代无机强酸硝酸，磨料PH值调整至6左右，偏向中性，尽量控制金属铬、镍离子产生量小，环境污染轻。The inorganic strong acid nitric acid is replaced by organic acid and weak acid, and the PH value of the abrasive is adjusted to about 6, which is biased towards neutrality, and the production of metal chromium and nickel ions is minimized and the environmental pollution is light.
二氧化硅极难溶于水，本发明采用吐温0.05%加0.2%聚乙二醇配比，分散及微溶二氧化硅技术难题，配比成高细度的粗1500目、精3000目两种浆料。重金属捕捉剂凝胶及吸附重金属离子，从而可以。Silica is extremely difficult to dissolve in water. The present invention adopts the ratio of Tween 0.05% and 0.2% polyethylene glycol to disperse and slightly soluble silicon dioxide. Two pastes. The heavy metal scavenger gels and adsorbs heavy metal ions, so it can be.
调整磨液酸碱度，对金属铬、镍离子产生的影响，同时加入重金属捕捉剂，使磨液达到环保排放要求。加入重金属捕捉剂质量比0.5-2%。如黄原酸酯类和二硫代胺基甲酸盐类衍生物(DTC类) 或其凝胶。Adjust the pH of the grinding fluid to affect the metal chromium and nickel ions, and at the same time add a heavy metal scavenger to make the grinding fluid meet the environmental discharge requirements. The mass ratio of adding heavy metal scavenger is 0.5-2%. Such as xanthates and dithiocarbamate derivatives (DTCs) or their gels.
二氧化硅微粉分散及微溶到水中，先配成20%二氧化硅浆料，加柠檬酸10%，能促进二氧化硅微粉分散及微溶，不沉淀。最后配制成所设定的浓度。再配制含有质量为2.2±0.2%二氧化硅浆料。Silica powder is dispersed and slightly soluble in water. First make 20% silica slurry and add 10% citric acid, which can promote the dispersion and slight solubility of silica powder without precipitation. Finally, it is formulated to the set concentration. Then prepare a slurry containing 2.2±0.2% silica by mass.
磨料中加入葡萄糖酸钠，其质量比为1.5-2.5%，因葡萄糖酸钠可以用作金属表面处理以及水处理等行业作高效螯合剂，钢铁表面清洗剂，具有优异的缓蚀阻垢作用，所以被广泛用于水质稳定剂，甚至在全PH范围内部有作用，可用于食品添加剂，能去除镜面板表面白点及增强亮度，达到完美的镜面状态。Sodium gluconate is added to the abrasive, and its mass ratio is 1.5-2.5%. Because sodium gluconate can be used as a high-efficiency chelating agent in metal surface treatment and water treatment industries, as a cleaning agent for steel surface, it has excellent corrosion and scale inhibition effect. Therefore, it is widely used as a water stabilizer, and even has a role in the full PH range. It can be used as a food additive, which can remove the white spot on the surface of the mirror panel and enhance the brightness to achieve a perfect mirror state.
磨料介质研磨抛光机（磨头）的中央加料（圆心位置流入研磨浆料）效果更好。The central feeding of the abrasive media grinding and polishing machine (grinding head) (the grinding slurry flowing into the center of the circle) is better.
本发明基本不用酸，不采用氧化铝微粉磨料，氧化铝微粉研磨抛光机羊毛毡磨头快速旋转出现磨头结合面发焦发硬现象，导致不锈钢板面出现磨头印（呼啦圈）等不合格品行的缺陷。The invention basically does not use acid, and does not use alumina micropowder abrasives. The rapid rotation of the wool felt grinding head of the alumina micropowder grinding and polishing machine causes the phenomenon of coke and hardening of the joint surface of the grinding head, resulting in the appearance of grinding head marks (hula hoop) on the surface of the stainless steel plate. Defects of good character.
本发明的羊毛毡磨头发焦的概率大大降低，研磨切削的效率得到很大的提高，不锈钢研磨抛光后的粗糙度达到镜面板的技术要求。The wool felt of the invention greatly reduces the probability of hair coke grinding, greatly improves the grinding and cutting efficiency, and the roughness of the stainless steel after grinding and polishing meets the technical requirements of the mirror panel.
有了新方法新工艺，再经过数十次的配比研磨对比最后确定了3%柠檬酸与2.2%二氧化硅组成最佳配比制成研磨抛光浆料。因柠檬酸是一种重要的有机酸，用于食品添加剂，对金属表面也起清洁作用，可当金属清洗剂使用；二氧化硅是硅原子跟四个氧原子形成的球形结构的原子晶体，整个晶体又可以看作是一个巨大分子，是一种坚硬难溶的球形固体,呈酸性氧化物，二氧化硅当中间载体，能去除不锈钢表面高点（也即磨削力），再进行研磨抛光，完全能够使不锈钢表面达到镜面状态。With the new method and new technology, after dozens of times of grinding and comparison, the optimal ratio of 3% citric acid and 2.2% silica was finally determined to make the grinding and polishing slurry. Because citric acid is an important organic acid, it is used in food additives, and it also has a cleaning effect on metal surfaces. It can be used as a metal cleaning agent; silica is an atomic crystal with a spherical structure formed by silicon atoms and four oxygen atoms. The whole crystal can be regarded as a huge molecule, which is a hard and insoluble spherical solid, which is an acidic oxide. Silica acts as an intermediate carrier, which can remove the high point on the surface of the stainless steel (that is, the grinding force), and then grind it. Polishing can completely make the stainless steel surface reach a mirror state.

实施例2Example 2
本实施例与实施例1的区别在于，二氧化硅微粉分散及微溶到水中，先配成20%二氧化硅浆料，加柠檬酸10%，能促进二氧化硅微粉分散及微溶，不沉淀。最后配制成所设定的浓度。二氧化硅极难溶于水，采用表面活性剂吐温（多规格的吐温均可）0.05%加0.2%聚乙二醇配比，分散及微溶二氧化硅技术难题，配比成粗1500目、精3000目两种浆料。The difference between this example and Example 1 is that the silica fine powder is dispersed and slightly soluble in water. First, 20% silica slurry is prepared, and 10% citric acid is added, which can promote the dispersion and slight solubility of the silica fine powder. Does not settle. Finally, it is formulated to the set concentration. Silica is extremely difficult to dissolve in water. The surfactant Tween (Tween of various specifications is acceptable) is used in the ratio of 0.05% and 0.2% polyethylene glycol. It is difficult to disperse and slightly soluble silica, and the ratio becomes coarse. 1500 mesh and fine 3000 mesh two kinds of slurry.
磨料中加入质量比为2%葡萄糖酸钠，因葡萄糖酸钠可以用作金属表面处理以及水处理等行业作高效螯合剂，钢铁表面清洗剂，具有优异的缓蚀阻垢作用，所以被广泛用于水质稳定剂，甚至在全PH范围内部有作用，可用于食品添加剂，能去除镜面板表面白点及增强亮度，达到完美的镜面状态。The mass ratio of 2% sodium gluconate is added to the abrasive. Because sodium gluconate can be used as a high-efficiency chelating agent in metal surface treatment and water treatment industries, as a cleaning agent for steel surface, it has excellent corrosion and scale inhibition effect, so it is widely used. It can be used as a water stabilizer, even in the full PH range, and can be used as a food additive to remove white spots on the surface of mirror panels and enhance brightness to achieve a perfect mirror state.
并将柠檬酸与二氧化硅配置成的浆料磨液,经过试磨具有意想不到的效果。The slurry grinding liquid prepared with citric acid and silica has unexpected results after trial grinding.
