Embodiment 1

[0025] The inorganic acid is phosphoric acid, the organic acid is oxalic acid and citric acid, the surfactant is sodium dodecylbenzenesulfonate or op-10 emulsifier, the polar solvent is deionized water, and the weight ratio of each component is as follows:

[0026] 3 parts of phosphoric acid; 10 parts of oxalic acid; 10 parts of citric acid; 5 parts of hydrogen peroxide; 71 parts of deionized water. Mix the above components and stir evenly, and heat appropriately to help dissolve oxalic acid and the like. Then add sodium dodecylbenzene sulfonate or op-10 emulsifier into the solution, the weight ratio is 1 part, and after stirring evenly, the granite surface can be painted.

[0027] The process of using rust remover to treat granite: In the process of rust removal on granite surface, the treated object should be carried out under the condition of ventilation and light as much as possible, and the treated granite should be kept off the ground with non-polluting materials.

Embodiment 2

[0029] The organic acid is phytic acid, oxalic acid and citric acid, the surfactant is sodium dodecylbenzenesulfonate or op-10 emulsifier, the polar solvent is deionized water, and the weight ratio of each component is as follows:

[0030] 5 parts of phytic acid; 10 parts of oxalic acid; 10 parts of citric acid; 5 parts of hydrogen peroxide; 69 parts of deionized water. Mix and stir the above components evenly, and heat properly. Then add sodium dodecylbenzenesulfonate or op-10 emulsifier into the solution, the weight ratio is 1 part, and stir evenly.

[0031] The granite process is the same as in Example 1.

Embodiment 3

[0033] The organic acid is glycolic acid, citric acid and maleic acid, the surfactant is sodium dodecylbenzenesulfonate or op-10 emulsifier, the polar solvent is deionized water, and the weight ratio of each component is as follows:

[0034] 15 parts of glycolic acid; 10 parts of citric acid; 15 parts of maleic acid; 15 parts of hydrogen peroxide; 80 parts of deionized water. Mix and stir the above components evenly, and heat properly. Then add sodium dodecylbenzenesulfonate or op-10 emulsifier into the solution, the weight ratio is 10 parts, and stir evenly.

[0035] The granite process is the same as in Example 1.

Abstract

The invention relates to a granite rust remover which is prepared by mixing the following components in parts by weight: 15-50 parts of one or more of inorganic acids and organic acids, 1-15 parts of surface active agent, 1-15 parts of hydrogen peroxide and 30-80 parts of polar solvents. The inorganic acid is preferably phosphoric acid and / or hydrochloric acid, the organic acid is preferably at least one of glycolic acid, glyoxylate, oxalic acid, phytic acid, citric acid, malic acid, maleic acid and fumaric acid, and the surface active agent is sodium dodecyl benzene sulfonate or op-10 emulsifier. The rust remover of the invention is smeared on the granite surface, can form a stable colorless complex with iron after reacting for 1-2 days, remove rusty points and rusty lines of the granitein a short time without influencing the granite luster or leaving trails and rapidly remove rust on the granite surface with high efficiency.

Description

technical field [0001] The invention relates to a rust remover for removing rust spots on granite. Background technique [0002] With the development of the economy, the application of decorative stone in people's life is becoming more and more extensive. Among them, granite is favored by people because of its good physical properties and stable chemical properties, and is widely used in the decoration of homes and public places. But granite also has its own problems, one of which is rust spots on the surface, and rust removal has become a focus of granite surface treatment. The reason for the rust spots on the surface of granite mainly comes from two aspects: one is external rust pollution, such as the rust of metal utensils placed on the stone surface will pollute the stone surface and leave rust on it; It is the reason of the stone itself. Some granite minerals contain iron oxide, which is further oxidized under humid conditions, and diffuses with water vapor, and gradu...
