Embodiment 1

[0014] A kind of environment-friendly cleaning agent, the mass percent of each component of this cleaning agent is:

[0015]

[0016] The balance is pure water; the pH value of the environmental cleaning agent is 6.

[0017] Preferably, the reducing agent is an amine compound, and the amine compound is any one of triethanolamine, hydroxylamine, aniline, and hydrazine hydrate.

[0018] Preferably, the attachment agent is xanthan gum or carboxymethyl cellulose.

[0019] The preparation technology of cleaning agent of the present invention is very simple, comprises the following steps:

[0020] (1) Under room temperature and normal pressure, get phosphoric acid, hydrochloric acid, oxalic acid and citric acid of corresponding mass percentage, be dissolved in water, stir, dissolve naturally;

[0021] (2) Under room temperature and normal pressure, take the reducing agent and the adhesive agent in the corresponding mass percentage, add them dropwise to the solution obtained in ...

Embodiment 2

[0024] The mass percent of each component of environment-friendly cleaning agent of the present invention is:

[0025]

[0026] The balance is pure water; the pH value of the environmental cleaning agent is 6.

[0027] Said hydrochloric acid concentration is 37%, density 1.19g / cm3, phosphoric acid concentration is 85%, density is 1.834g / cm3, brush stone material plane 1 time with cleaning agent of the present invention, wait for 20 minutes then; Brush again every 10 minutes and wait for another 10 minutes. The amount and cost of the cleaning agent will be greatly reduced, and the rust will be cleaned. It will not return to rust after being placed in a normal atmospheric environment for a year.

[0028] In the present invention, citric acid and sulfosalicylic acid are added to the cleaning agent, both of which are good complexing agents for iron ions. When treating stone surfaces with high iron content, rust can be completely removed without damaging stone materials and affe...

Abstract

The invention relates to a cleaning agent of a silicate product and particularly relates to an environment-friendly cleaning agent. The environment-friendly cleaning agent comprises the following components in percent by weight: 0.5%-0.7% of phosphoric acid, 1%-2% of hydrochloric acid, 0.2%-0.4% of oxalic acid, 2%-5% of a reducing agent, 0.1%-0.5% of an adhesive agent and the balance being pure water, wherein the PH value of the environment-friendly cleaning agent is 6-8. According to the environment-friendly cleaning agent, citric acid and sulfosalicylic acid which are iron ion complexing agents with relatively good quality are added in the cleaning agent; when a stone surface with the relatively high iron content is treated, iron rust can be completely removed and stone is not damaged, so that the surface smoothness of the stone is not affected and the effect is relatively good; the adhesive agent and the reducing agent can be used for prolonging retention reaction time of the cleaning agent on the stone surface and reducing use of the reducing agent, so that not only is treatment cost greatly saved, but also the stone surface is not rusted again while being placed in a common atmospheric environment, thereby saving energy and protecting the environment.

Description

technical field [0001] The invention relates to a cleaning agent for silicate products, in particular to an environment-friendly cleaning agent. Background technique [0002] Natural marble, granite, slate and artificial stone are widely used in the interior and exterior decoration of buildings because of their natural and beautiful patterns, clear gloss or textured concave-convex surfaces, and good friction strength. One of the earliest building materials used in the history of architecture. However, a considerable amount of stone, especially granite, has impurities such as rusty yellow spots, yellow lines, and leopard spots due to iron content. They will be discarded or processed as inferior products at low prices. Rust macula is the oxidation reaction of iron-containing substances in the stone body or into the stone, and the yellow or brown spots formed on the surface of the stone are mainly caused by natural reactions or the stone is mined, sawed, polished, cleaned and ...
