Abstract

The invention discloses a preparation method for an environment-friendly stone deruster. The preparation method comprises the following steps: placing hydrochloric acid, an emulsifier, triethavolamine, zinc stearate and thiourea dioxide into a stirring machine in parts by weight, and stirring at the temperature of 40-60 DEG C; adding hexamethylenetetramine, ammonium molybdate, benzotriazole, isobornyl acrylate, dibutyl phthalate and ethylene diamine tetramethylene phosphonic acid, heating to 60-80 DEG C within 3-6 min, performing ultrasonic treatment for 10-15 min, cooling to 40-60 DEG C, and continuously performing ultrasonic treatment for 10-15 min; placing the mixture into the stirring machine, and stirring at the ordinary temperature to obtain the environment-friendly stone deruster. The derusting performance of the deruster prepared by the method is improved, and the deruster has no impact on the surface of stone, meanwhile is simple in preparation process, avoids environment pollution, and has an excellent market prospect.

Description

technical field [0001] The invention relates to stone derusting technology, in particular to a preparation method of an environment-friendly stone derusting agent. Background technique [0002] Stone rust remover is to use professional stone chemical cleaning products to clean the natural and acquired rust spots on the surface and shallow surface of the stone, so as to restore the texture, appearance and decorative effect of the stone itself. [0003] The material composition inside the stone contains hematite and pyrite. These iron minerals are oxidized in contact with the air to form ferric oxide (rust), which seeps out through the capillary pores of the stone. At the same time, the stone cannot be used during use. Avoid contact with iron objects. The residues of these iron objects are coated on the surface of the stone and will be oxidized to form rust pollution. [0004] Existing derusting agents are easy to damage the surface of the stone while derust...
