Environment-friendly rust remover for stone containing iron impurities, and preparation method thereof
The invention discloses an environment-friendly rust remover for stone containing iron impurities, and a preparation method thereof. The environment-friendly rust remover is prepared from, by mass, 15-30% of organic acid, 0.5-2% of inorganic acid, 0.5-1.5% of a penetrant, 5-8% of ammonium compounds, 1-5% of paraffin oil, 0.5-1.5% of alcohol amine, and the balance of water. The organic acid in the rust remover has a coordination effect and can be coordinated with iron ions to generate Fe<2+> and Fe<3+> so as to be complexed with the iron ions, so that a stable complex is generated for further rapid rust removal; after the stone rust remover disclosed by the invention is used for removing rust, an adsorption film can be formed on the surface of the stone to achieve the purpose of removing rust without re-rusting, and the natural color of the stone is kept; and the method is simple in process and free of environmental pollution.
本发明公开了一种含铁杂质石材的环保除锈剂及其制备方法。所述环保除锈剂按质量分数计由以下组分组成：有机酸15%~30%，无机酸0.5%~2%，渗透剂0.5%~1.5%，铵类化合物5%~8%，石蜡油1%~5%，醇胺0.5%~1.5%，余量为水。本发明所述除锈剂中的有机酸具有配位作用，可与铁离子配位产生Fe2+、Fe3+以致络合铁离子，使其生成稳定的络合物以便进一步快速除锈；本发明的石材除锈剂除锈后，可在石材表面形成吸附膜以达到除锈不返锈的目的，并保持石材本色；本发明工艺简单且对环境无污染。
