Description
Technical Field
The application relates to the technical field of detergent preparation, in particular to a biological enzyme detergent for a metal surface and a preparation method thereof.
Background
In the technical field of pretreatment of metal surfaces, oil stains on the metal surfaces occupy a very important position, and if the metal surfaces are not cleaned cleanly, domestic products such as later-stage coating and the like can be affected, and even the whole process cannot be carried out. The dirt on the metal surface mainly comprises liquid dirt and solid dirt, wherein the liquid dirt is mineral oil, animal oil, vegetable oil and the like, and the solid dirt is often dust, carbon black, rust and the like. While solid soils are often surrounded by liquid soils, solid soils are typically removed only if the liquid soil is removed. In the current industrial operation, the common metal surface cleaning methods mainly comprise chemical alkaline cleaning, chemical acid cleaning and organic solvent cleaning, and the chemical alkaline cleaning and the chemical acid cleaning can cause certain corrosion to the metal surface and damage to the environment and the health of operators. The organic solvent is usually cleaned by using inflammable and explosive organic matters such as kerosene, gasoline and the like as main decontamination substances, and the overall safety of the cleaning agent is poor.
At present, a more efficient and safe method is a water-based cleaning agent cleaning method, however, the method still has certain defects in use, for example, most of surfactants and inorganic salts contained in the metal surface cleaning agent contain phosphorus, ammonia nitrogen, COD and other pollutants, cleaning agents with larger concentration are needed in cleaning, the cleaning temperature is higher, the time is longer, the cleaning cost is higher, in addition, most of the current water-based cleaning agents are special cleaning agents for certain metals, cannot be widely applied to other metal surfaces, and the application range is narrower.
Therefore, there is still a need to develop a metal surface detergent which is excellent in detergency, low in use cost and wide in application range.

As can be seen from the test results in Table 2, the biological enzyme detergent for the metal surface has excellent decontamination performance and corrosion inhibition performance by scientifically adjusting the specific compositions of the surfactant and other reagents in the detergent. The application carries out a great deal of researches and experiments on the surfactant, selects a plurality of surfactants suitable for the application, and can obtain obviously higher oil stain cleaning rate compared with the prior art by compounding the surfactants according to a certain proportion. Further, as is clear from the experimental results of examples 3, 5 and 6, when the ratio of NP-12 to NP-8.6 in the surfactant is 1:2.5-4, the detergency of the detergent can be further improved even if the total amount of the surfactant is the same, probably because a specific amount ratio is present in the surfactant system of the present application, at which ratio a larger number of micelles can be formed, the surface tension of the system is further reduced, and thus a better detergency effect can be obtained.
For the detergent with the metal as the cleaning object, the corrosion effect on the base material is not negligible, and the excellent anti-corrosion effect can be obtained on the premise of not affecting the decontamination performance of the detergent by selecting and compounding the proper corrosion inhibitor. In comparative examples 1 and 2, only the benzotriazole or urotropine is added, the corrosion prevention mechanism is single, the corrosion rate of the detergent to the base material is obviously improved compared with example 5 containing the benzotriazole and urotropine, but the oil stain cleaning rate is still high. The comparative example 3 greatly reduces the total amount of surfactant, and the oil stain cleaning rate is expected to be remarkably reduced, however, the corrosion rate of the detergent of comparative example 3 on the substrate is greatly increased, and the applicant repeatedly tests to observe the result, probably because the comparative example 3 has relatively large amount of surfactant, and micelle can be formed to wrap the corrosion inhibitor component before the decontamination effect is exerted, so that the corrosion inhibitor component is prevented from being polluted or damaged by oil stains or other stains to cause inactivation, and the micelle is gradually consumed to release the wrapped corrosion inhibitor along with the progress of the decontamination process, so that the corresponding anti-corrosion and corrosion inhibition effects can be exerted; the surfactant in comparative example 3 is used in a small amount, so that the corrosion inhibitor is difficult to effectively wrap, and the corrosion inhibitor is polluted or damaged by oil stains or other stains, so that the expected anti-corrosion effect is difficult to be exerted. The type and amount of the components of comparative example 4 were the same as in example 5, except that the components were mixed together in the preparation of comparative example 4, and it was confirmed from the test results that the greasy dirt cleaning rate was not significantly different from that of example 5, but the corrosion rate to the substrate was significantly higher than that of example 5, and it was also confirmed that if the surfactant did not form an effective package for the corrosion inhibitor, significant corrosion to the substrate could be caused.
Comparative examples 5-7 the surfactant type was changed to other surfactant types common to the cleaning agent field based on examples 1-3, resulting in significantly poorer greasy dirt cleaning rate and higher corrosion rate, probably because the surfactant of comparative examples 5-7 formed no good compatibility with other components of the present application, or the formed micelles were difficult to effectively encapsulate the corrosion inhibitor component, indicating that the surfactant and other components in the detergent of the present application formed a unified whole, and excellent detergency performance and corrosion resistance could be obtained within the range of the amount of the present application.
Cycle performance test
Taking a stainless tinplate, and measuring the weight m 0 About 5g of greasy dirt was applied to the tinplate, and the weight m of the tinplate after coating was measured 1 Obtaining a sample to be washed; the above procedure was repeated to prepare a plurality of samples to be washed.
Using the detergent of example 5, adding deionized water to prepare a cleaning solution with a mass concentration of 5%, placing the cleaning solution and the sample to be cleaned in an ultrasonic cleaner, ultrasonically cleaning for 4min at an ultrasonic temperature of 50 ℃, then rinsing for 1 min with flowing water at 30 ℃, drying the cleaned sample to a constant weight, and measuring the weight m of the dried sample 2 The oil stain cleaning rate was calculated according to the following formula: oil stain cleaning rate= (m 1 -m 2 )÷(m 1 -m 0 )×100％。
And replacing another sample to be washed, adding the sample to the used cleaning liquid, repeating the cleaning procedure for a plurality of times, and calculating the oil stain cleaning rate after each cleaning procedure is completed, wherein the result is shown in Table 3.
