Description
Technical Field
The invention relates to the technical field of building decoration, in particular to a cement cleaning agent.
Background
In the field of building decoration, stone materials such as marble, slate, granite, artificial stone and the like are widely used. However, in daily use, the stone surface is very easy to be stained with dust or greasy dirt due to a large number of pore canals, and the aesthetic degree is affected. The traditional method is to clean with a large amount of clean water, so that manpower and material resources are consumed, and the effect is poor.
At present, a large number of different stone cleaning agents exist, and stains on the stone surface can be effectively removed. A marble cleaning agent is disclosed in chinese patent CN107523434, which can be used for cleaning building-modifying marble. The weight ratio of each component is 28-35% of inorganic acid, 4.5-15% of anionic surfactant, 2.5-10% of nonionic surfactant, 0.5-2% of alkaline auxiliary agent, 0-0.1% of complexing agent and the balance of distilled water; chinese patent CN103525583 discloses a silicate product cleaning agent which can effectively remove greasy dirt, wherein the weight ratio of each component is 30-40% of sodium hypochlorite, 5-10% of calcium carbonate, 5-10% of n-bromopropane, 5-15% of acetone, 5% of ethyl acetate, 15% of surfactant and the balance of deionized water; in Chinese patent CN105567466, a marble cleaning agent is disclosed, wherein the weight ratio of each component is 8-10% of sodium salt, 6-8% of glycolic acid, 1-2% of benzene, 1-2% of ammonium chloride and the balance of distilled water; liu Renzhi (research on neutral cleaning agent and cleaning process of rust on stone surface) uses oxalic acid, hydrazine hydrate and alkaline auxiliary agent as raw materials to prepare a neutral cleaning agent which can effectively remove rust; chen Zhenzhen et al (development of Environment-friendly cement cleaning agent) developed a cement cleaning agent with pH of 5-6, which can replace strong acid cleaning agents and compare the disintegration effects of different organic acids on cement.
However, the research shows that the conventional stone cleaning agent has the following defects: (1) the cost is high, various auxiliary agents and auxiliary materials are added into the cleaning agent, and the material cost is increased; (2) the cleaning capability is poor, dirt and the like are easy to be hidden in surface pore canals due to the structural characteristics of stone, so that the cleaning effect is poor, the dirt composition is complex, organic components (such as greasy dirt and the like) and inorganic components (such as rust and the like) are contained, and the applicability of the common cleaning agent is poor; (3) the environment protection performance is poor, in order to improve the removal effect of greasy dirt, organic solvents such as n-bromopropane, trichloroethylene and the like are added into some cleaning agents, and the organic solvents volatilize to cause harm to the body health of a human body; (4) the cleaning agent is used for corroding stone, and uses strong acid such as hydrochloric acid, nitric acid and the like as raw materials to damage the surface of the stone.
Therefore, it is highly demanded to find a cement cleaning agent which has good cleaning ability, does not corrode stone, and is low in cost, safe and environment-friendly.
Disclosure of Invention
In order to solve the problems, the invention provides a cement cleaning agent which is mainly prepared by mixing a novel surfactant comprising polyoxyethylene octyl phenol ether-10, alpha-sodium alkenyl sulfonate, fatty alcohol polyoxyethylene ether and coconut oil fatty acid diethanolamide with organic acid, can remove cement, can effectively remove greasy dirt and cement stains on the surface of stone, and has the advantages of strong hard water resistance, good stability, low cost, strong cleaning capability, environmental protection, no corrosion to stone and the like.
In one aspect, the present invention provides a surfactant composition comprising polyoxyethylene octyl phenol ether-10, sodium alpha-alkenyl sulfonate, and fatty alcohol-polyoxyethylene ether.
According to the invention, a large number of researches prove that the surfactant prepared by combining polyoxyethylene octyl phenol ether-10, alpha-sodium alkenyl sulfonate and fatty alcohol polyoxyethylene ether has very good hard water resistance and very strong cement cleaning effect, can remove cement, can effectively remove greasy dirt, cement stains and other stains on the surface of stone, does not corrode the stone, and is low in cost, thus being particularly suitable for preparing cement cleaning agents.
For the existing surfactant, hard water is easy to complex with the existing surfactant, so that the cleaning capacity of the surfactant is reduced, cement is difficult to thoroughly clean, and residues are easy to leave.
The invention provides a surfactant composition which has very strong hard water resistance, can exert excellent cement cleaning effect in hard water, and has wider application.
Further, the composition also includes coconut fatty acid diethanolamide.
Further, the EO number of the fatty alcohol-polyoxyethylene ether is 8-11.
The EO number of the fatty alcohol-polyoxyethylene ether can directly influence the performance of the surfactant, and when the EO number is 8-11, the fatty alcohol-polyoxyethylene ether has better oleophylic performance and higher degreasing performance. However, if the EO number of the fatty alcohol-polyoxyethylene ether is too high, the hydrophilic performance is poor and the fatty alcohol-polyoxyethylene ether is difficult to wash off; if the EO number is too low, the lipophilicity is poor and the effect of cleaning cement is hardly obtained, so that it is preferable to use a fatty alcohol polyoxyethylene ether (AEO-9) having an EO number of 8 to 11, and most preferably an EO number of 9.
Further, the composition comprises, by mass, 1-5% of polyoxyethylene octyl phenol ether-10, 1-3% of alpha-sodium alkenyl sulfonate, 1-5% of fatty alcohol polyoxyethylene ether and 1-5% of coconut oil fatty acid diethanolamide.
In another aspect, the present invention provides a cement cleaner comprising a surfactant as described above and an organic acid.
The organic acid is added into the surfactant, so that the alkaline environment of the surfactant can be synthesized, the pH of the cement cleaning agent is more stable, the prepared cement cleaning agent has more stable performance, and the phenomena of layering or crystallization precipitation and the like can not occur after long-term storage.
The inorganic acid has strong acidity and is easy to corrode the ground, and the invention preferably adopts the organic acid to prepare the cement cleaning agent.

Table 1, cement cleaning agent Performance comparison prepared in examples 1 to 7
As can be seen from table 1, when any one of polyoxyethylene octyl phenol ether-10, alpha-sodium alkenyl sulfonate, fatty alcohol polyoxyethylene ether and coconut oil fatty acid diethanolamide is absent, the hard water resistance of the prepared cement cleaning agent is reduced, and the cleaning ability is also remarkably reduced; when the citric acid is absent, the system is unstable, and the phenomena of delamination, crystallization, and the like are easy to occur after long-term placement; when oxalic acid is used for replacing citric acid, the cleaning capacity of the prepared cement cleaning agent is reduced, and the stability is also reduced. The cement cleaning agent provided in the embodiment 1 has the advantages of optimal cleaning capability, hard water resistance and stability, no corrosion to stone, and obviously improved performance compared with other cement cleaning agents.
EXAMPLE 9 comparison of Cement cleanser Performance of different formulations
This example was prepared according to the method provided in example 1, using the following 6 formulations, each of which is:
formula 1:15% Na 2 CO 3 0.2% sodium dodecyl benzene sulfonate, 2% NH 4 Cl,3.5% urea;
formula 2:1% of coconut oil fatty acid diethanolamide, 1% of fatty alcohol polyoxyethylene ether (AEO-9), 1% of alkylphenol polyoxyethylene and 1% of Na 2 CO 3 ；
Formula 3:4% of citric acid, 5% of sodium fatty alcohol polyoxyethylene ether sulfate, 1% of fatty alcohol polyoxyethylene ether (AEO-7) and 1% of cocamidopropyl amine oxide;
formula 4:4% of citric acid, 1% of coconut oil fatty acid diethanolamide, 1% of alkylphenol ethoxylates, 1% of EDTA-2Na,0.1% of disodium ethylenediamine tetraacetate, and 4% of fatty alcohol polyoxyethylene ether sodium sulfate;

formula 6:4% of citric acid, 2% of polyoxyethylene octyl phenol ether-10, 2% of alpha-sodium alkenyl sulfonate, 2% of fatty alcohol polyoxyethylene ether and 1.5% of coconut oil fatty acid diethanolamide.
This example is directed to the cement cleaners prepared in examples 1 to 7, and examined for hard water resistance, stability, whether or not to corrode stone, cleaning ability, and cement cleaning ability, respectively, and the detection method is as shown in example 8. The test results are shown in Table 2, wherein the clear effect pictures of the formulas 3 to 6 are shown in FIG. 1, and the stains are carbon black and vegetable oil compositions; the effect of the cement cleaning agent prepared by the formula 6 on cleaning the cement on the stone surface is shown in fig. 2 and 3, wherein fig. 2 is a picture before cleaning, and fig. 3 is a picture after cleaning.
Table 2 comparison of Cement cleaning agent Performance of different formulations
As can be seen from Table 2, the cement cleaner prepared with different formulations has quite different properties. The formula 1 and the formula 2 have no organic acid, so that the system is very unstable, and layering or crystallization precipitation occurs; in contrast, the cement cleaner prepared in formula 6 has more excellent performances in all aspects. It can be seen that the components in the cement cleaning agent provided by the formula 6 cannot be replaced at will, otherwise, the performance of the cement cleaning agent is seriously affected, and the cement cleaning agent with strong cleaning capability, high stability, strong hard water resistance and excellent performances in all aspects of no corrosiveness to stone is difficult to obtain.
As can also be seen from fig. 1, the cleaning effect of formulation 6 is the best, significantly better than the other formulations, and the cleaning effect of formulation 4 is the worst, significantly worse than the other formulations.
Example 10 Effect of different ratio relationships of the Components on Cement cleanser Properties
In this example, the cement cleaner was prepared by the method provided in example 1, wherein the contents of the components are shown in table 3, and the hard water resistance, stability, corrosion resistance, cleaning ability and cement cleaning ability of the cement cleaner were examined, the detection method is shown in example 8, and the detection results are shown in table 3.
TABLE 3 influence of different ratio relationships of the Components on the Cement cleanser Performance
As can be seen from Table 3, the proportion of each component in the formulation of the cement cleaning agent has a certain influence on the performance of the cement cleaning agent, the content of the citric acid has an obvious influence on the stability and cleaning effect of the cement cleaning agent, the stability and cleaning effect of the cement cleaning agent can be influenced by the lower or higher content of the citric acid, and the cement cleaning agent with more stable and better cleaning effect can be prepared only when the content of the citric acid is in the range of 3-10%, especially when the content of the citric acid is 4%.
The content of the polyoxyethylene octyl phenol ether-10 has a certain influence on the cleaning effect and the hard water resistance of the cement cleaning agent, when the content of the polyoxyethylene octyl phenol ether-10 is lower than 1%, the cleaning effect is poor, the hard water resistance is weak, when the content of the polyoxyethylene octyl phenol ether-10 is higher than 5%, the cleaning effect is difficult to continuously improve, the cost is increased, and the method has no practical significance, so that the content of the polyoxyethylene octyl phenol ether-10 is more suitable in the range of 1-5%, and particularly, when the content of the polyoxyethylene octyl phenol ether-10 is 2%, the cleaning effect and the hard water resistance of the prepared cement cleaning agent are optimal.
The content of the alpha-sodium alkenyl sulfonate has certain influence on the cleaning effect and the hard water resistance of the cement cleaning agent, when the content of the alpha-sodium alkenyl sulfonate is lower than 1%, the cleaning effect is poor, the hard water resistance is very weak, when the content of the alpha-sodium alkenyl sulfonate is higher than 3%, the cleaning effect and the hard water resistance are difficult to continuously improve, bubbles are obviously increased, the cost is increased, and the method has no practical significance, so that the content of the alpha-sodium alkenyl sulfonate is proper in the range of 1-3%, and especially when the content of the alpha-sodium alkenyl sulfonate is 2%, the cleaning effect and the hard water resistance of the prepared cement cleaning agent are optimal.
The content of the fatty alcohol-polyoxyethylene ether has certain influence on the cleaning effect and the hard water resistance of the cement cleaning agent, when the content of the fatty alcohol-polyoxyethylene ether is lower than 1%, the cleaning effect is poor, and the hard water resistance is weak, when the content of the fatty alcohol-polyoxyethylene ether is higher than 5%, the cleaning effect is difficult to continuously improve, and the cost is increased without practical significance, so that the content of the fatty alcohol-polyoxyethylene ether is more suitable in the range of 1-5%, and especially when the content of the fatty alcohol-polyoxyethylene ether is 2%, the cleaning effect and the hard water resistance of the prepared cement cleaning agent are optimal.
The content of the coconut oil fatty acid diethanolamide has a certain influence on the cleaning effect and the hard water resistance of the cement cleaning agent, when the content of the coconut oil fatty acid diethanolamide is lower than 1%, the cleaning effect is poor, the hard water resistance is weak, when the content of the coconut oil fatty acid diethanolamide is higher than 5%, the cleaning effect is difficult to continuously improve, the cost is increased, and the method has no practical significance, so that the content of the coconut oil fatty acid diethanolamide is more suitable in the range of 1-5%, and especially when the content of the coconut oil fatty acid diethanolamide is 1.5%, the cleaning effect and the hard water resistance of the prepared cement cleaning agent are optimal.
When the content of each component in the cement cleaning agent is increased in a multiplied way (see the last group of the table 3), the hard water resistance and the stability of the cement cleaning agent are not obviously affected, the cement cleaning agent is not corrosive to stone, but the cleaning capability is reduced, and in the actual use process, a large amount of water is required to clean the rest surface activity due to the too high total content, and the cement cleaning agent has the advantages of more bubbles, high cost and difficulty in cleaning.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention should be assessed accordingly to that of the appended claims.
