Abstract
The invention discloses a cleaning agent for stones and stone cultural relics and a preparation method thereof. The cleaning agent can remove yellow spots from the surfaces of the stones and the stone cultural relics, wherein the yellow spots comprise rust yellow spots and organic yellow spots. The cleaning agent comprises organic acid, a reducing agent and water, wherein the organic acid mainly comprises monocarboxylic, dicarboxylic and polycarboxylic low-carbon acid (--COOH), sulfonic acid (--SO3H) and the like; and the reducing agent mainly comprises amine compounds. Cleaning liquid and waste liquid are neutral, do not have corrosion effect on the stones, and do not damage the environment. The cleaning agent has oxidation resistance, low cost, extremely low concentration and a simple operating method, is convenient to carry, can be prepared in advance, and can also be prepared on site.
Description
Technical field
The present invention relates to a kind of chemicals of removing stone material and stone cultural artifact surface rust macula lutea and organic macula lutea, particularly a kind of preparation method of neutral stain remover.
Background technology
Many building decoration stone materials or large-scale stone cultural artifact; Because stone material self iron-bearing mineral is oxidized; Perhaps stone material receives the pollution of extraneous iron rust or coloring matter (like straw rope, packing case carton, ight soil, food, tea, coffee, fruit juice etc.), and the surface can glow the xanchromatic spot, and this not only influences the outward appearance of buildings; Change the original appearance of stone cultural artifact, but also can influence the life-span of stone material.There is following problem in many macula lutea clean-out systems that go both at home and abroad at present: 1, be acid or alkaline, can cause corrosion to stone material; 2, concentration higher, and more or less contain tensio-active agent etc., get into and be difficult to remove behind the stone material micropore clean, can stay hidden danger or contaminate environment.
Summary of the invention
The object of the present invention is to provide a kind of clean-out system of removing stone material and stone cultural artifact surface macula lutea, it is neutral that this clean-out system and waste liquid thereof all are, and stone material is not had corrosive nature, and environment is not had destruction.Itself has antioxygenation clean-out system, and is with low cost, and concentration is extremely low, and is easy to carry, can prepare in advance, also can join first usefulness at present, and working method is simple.
Concrete technical scheme of the present invention is following:
The present invention is a kind of neutral stone material and stone cultural artifact surface macula lutea clean-out system, prepares raw material according to the following portions by weight ratio: organic acid, 1.7 ~ 2.0 %; Reductive agent, 2.0 ~ 4.0 %; Water, 94.0 ~ 96.0 %; All percentage ratios are mass percent.
Organic acid of the present invention is monobasic, binary, low-carbon (LC) carboxylic acid cpd solid such as polynary, and the low-carbon (LC) carboxylic acid cpd is any of formic acid, acetate, oxalic acid, phenylformic acid, Whitfield's ointment, Hydrocerol A.
Reductive agent of the present invention is an aminated compounds matter, and aminated compounds is any of trolamine, azanol, aniline, Hydrazine Hydrate 80.
Clean-out system of the present invention, its pH value is 6.5 ~ 8.0.
The preparation method of neutral stone material of the present invention and stone cultural artifact surface macula lutea clean-out system comprises the steps:
(1), under the room temperature normal pressure, get the organic acid and the water of corresponding ratio of weight and number, organic acid is dissolved in the water, stirs, dissolve naturally;
(2), under the room temperature normal pressure, get the reductive agent of corresponding ratio of weight and number, be added drop-wise in the solution that step (1) obtained, mix and to obtain neutral stone material and stone cultural artifact surface macula lutea clean-out system.
The operating procedure of clean-out system of the present invention preferably adopts application method construction, and is promptly with clean-out system that materials such as facial tissue, paper pulp or rubber powder is wetting, sticks on the macula lutea place of stone material, above covered with plastic film, treat to remove behind the substantially dry and stick thing, stick to doing with clear water again.
Compared with prior art, the present invention has following advantage:
1, the present invention adopts gentle organic monoacid, is difficult for producing acid mist; And with aminated compounds as neutralizing agent, make clean-out system and waste liquid all be neutral, can not corrode stone material and destroy environment;
2, the reductibility of amine substance has strengthened the clenaing effect of clean-out system among the present invention, and its antioxidant property has also reduced the possibility of yellowing of cleaning the back stone material because self iron compound is oxidized once more simultaneously;
3, clean-out system of the present invention does not contain strong acid, heavy metal ion and tensio-active agent etc., and waste liquid is easy to handle.
Embodiment
Below in conjunction with specific examples content of the present invention is described in detail, but is to be understood that content of the present invention does not receive the specifically described restriction of the following example.
Instance one
Under the room temperature normal pressure, get ratio of weight and number and be respectively 2.0% organic acid and 96% deionized water, the organic acid of this umber is dissolved in the water of this umber, and at the uniform velocity stirs dissolving naturally under the room temperature, cooling with glass stick; The adding ratio of weight and number is 2.0% amine reductive agent in above-mentioned solution, at the uniform velocity mixes to get final product.This solution is water white transparency, pH=6.5 ~ 7.0.Draw the wetting facial tissue of the above-mentioned solution of two droppers (about 2.5ml) with glue head dropper, stick stone surface rust staining Polluted area with facial tissue again, stone surface cleans up after 6 hours.
Instance two
Under the room temperature normal pressure, get ratio of weight and number and be respectively 1.7% organic acid and 94.0% deionized water, the organic acid of this umber is dissolved in the water of this umber, and at the uniform velocity stirs dissolving naturally under the room temperature, cooling with glass stick; The adding ratio of weight and number is 94% amine reductive agent in above-mentioned solution, at the uniform velocity mixes to get final product.This solution is water white transparency, pH=7.5 ~ 8.0.Draw the wetting facial tissue of the above-mentioned solution of two droppers (about 2.5ml) with glue head dropper, stick stone surface coffee, soy sauce stain zone with facial tissue again, stone surface cleans up after 6 hours.
Instance three
Under the room temperature normal pressure, get ratio of weight and number and be respectively 2.0% organic acid and 96% deionized water, the organic acid of this umber is dissolved in the water of this umber, and at the uniform velocity stirs dissolving naturally under the room temperature, cooling with glass stick; The adding ratio of weight and number is 2.0% amine reductive agent in above-mentioned solution, at the uniform velocity mixes to get final product.This solution is water white transparency, pH=6.5 ~ 7.0.Draw the wetting facial tissue of the above-mentioned solution of two droppers (about 2.5ml) with glue head dropper, stick stone surface soy sauce stain zone with facial tissue again, stone surface cleans up after 6 hours.
Above ratio all adopts ratio of weight and number.
