Description

Alkaline foam cleaning agent and preparation method thereof

Technical Field

The invention relates to the field of cleaning agents, and particularly relates to an alkaline foam cleaning agent and a preparation method thereof.

Background

The alkaline cleaning agent mainly aims at removing fat, protein and polysaccharide on the hard surface, and the current alkaline cleaning agent mainly aims at removing fat, protein and polysaccharide on the hard surface through the combination of alkaline substances and surfactants. The foam imparted by the surfactant selectively adsorbs soils, particularly solid soil particles, and reduces the degree of soiling of the wash liquor, thereby facilitating washing. The alkaline cleaning agent is foamed, and the foam can also carry away the washed oil drops and solid dirt particles, so that the cleaning is facilitated. The surfactant in the foam liquid film forms a mixed adsorption molecular layer with a hydrophilic group facing inwards and a hydrophobic group facing outwards in water, and when the foam is contacted with the organic dust, the hydrophobic group of the foam liquid film is easier to adsorb the organic dust than water molecules. In addition, the foam has a liquid-carrying capacity, the longer the foam is held on a hard surface, the longer the action of the cleaning agent on the dirt. Therefore, the stability and durability of the foam are core indexes of the foam cleaning agent.

For example, publication No. CN105925395A discloses a foam cleaning agent for animals and a preparation method thereof, wherein an anionic surfactant and a nonionic surfactant are mixed, so as to improve oil stain dissolution, improve the colloid performance of the cleaning agent and facilitate clean water washing. Publication No. CN106497703A discloses a cleaning agent containing gemini surfactant for farm use and a preparation method thereof, and publication No. CN106520399A discloses a cleaning agent for farm use and a preparation method thereof, the technical proposal is a mixture of anionic surfactant/gemini surfactant, nonionic surfactant, amphoteric surfactant and corrosion inhibitor, which mainly has the functions of disinfection and reducing the corrosion of disinfectant to equipment. The publication No. CN112961739A discloses a special high-efficiency foam cleaning disinfectant for farms, which is mainly compounded by alpha-sodium alkenyl sulfonate, an AOS surfactant, an anionic surfactant, a zwitterionic surfactant and an alkaline substance sodium hydroxide, wherein the alpha-sodium alkenyl sulfonate and the AOS surfactant are the same anions, and the zwitterionic surfactant shows anionic performance in an alkaline environment, so that the technical scheme is that the anionic surfactants are mixed, and the stability of the disinfectant in water is mainly improved. Publication No. CN110079402A discloses an environment-friendly composite alkaline foam cleaning agent and a preparation method thereof, wherein the cleaning agent comprises sodium hydroxide, a foaming agent, a foam stabilizer, a dispersing agent, a chelating agent and alkylolamide, wherein the foaming agent is an anionic surfactant and an amphoteric surfactant.

According to the technical scheme, most of the anionic surfactant, the nonionic surfactant and the zwitterionic surfactant are compounded to form foam to clean equipment, but the wall hanging time of the foam is short, so that the cleaning effect is poor, and the using amount of the cleaning agent is large.

The publication No. CN111440676A discloses a foam cleaning agent with disinfection and cleaning functions and a preparation method thereof, and the technical scheme is that a cationic surfactant, an anionic surfactant, a nonionic surfactant, a solubilizer, a chelating agent, an antirust agent, a pH regulator and micromolecular alcohol are compounded, so that the technical problems of corrosion of caustic soda to equipment and improvement of the disinfection function are solved, but the technical problem of short foam wall hanging time in the foam cleaning agent is still not solved.

In summary, the existing bath foam cleaning agent is mainly added with anionic surfactant and weak cationic surfactant with good foam stability, such as amine oxide CAO, alkanolamide 6501 and the like; adding soluble polymer material to increase foam viscosity, such as sodium polyacrylate, xanthan gum, etc.; the using concentration of the product is improved, and the thickness of the foam liquid film is increased. Although the methods can improve the foam stability to a certain degree, in use, the foam liquid is difficult to stay on a vertical surface for a long time due to the influence of temperature, gravity and the properties of a hard surface, and cannot meet the requirement of durable wall hanging, and particularly, the wall hanging property is worse under the condition of higher temperature in summer.

detection of the object: animal husbandry houses;

the detection method comprises the following steps: examples 17-19 of the present invention, comparative examples 1-5 and imported brand of alkaline foam cleaner were tested using an Italian import PA foam watering can, a Kyoto high pressure washer, germany, and a 3M ATP fluorescence detector.

Before the experiment begins, an ATP detector is used for detecting the surface cleanliness; and (3) washing the wall surface by using high-pressure water, fully wetting the wall surface by using the high-pressure water after 5min, and sampling and detecting the data before cleaning by using an ATP detector. Spraying foam for 20min, washing the foam with a high-pressure water gun, sampling and detecting the same sampling point with an ATP fluorescence detector again, wherein the test results are shown in Table 1;

TABLE 1ATP detection data

As is apparent from examples 17 to 19 and comparative examples 1 to 2, comparative example 1 is a mixture of a simple addition of an anionic/nonionic surfactant, and comparative example 2 is a mixture of a simple cationic/nonionic surfactant. As can be seen from comparative example 1 and comparative example 2, the number of colonies after both cleaning was higher than that of the anion/cation/non-three ion combination, indicating that the cleaning effect was poor. The cleaning agent compounded by the anionic surfactant, the cationic surfactant and the nonionic surfactant has better cleaning effect than a foam cleaning agent mixed by pure anionic surfactant, pure nonionic surfactant or pure cationic surfactant.

Meanwhile, as can be seen from comparison of examples 17 to 19 with comparative examples 3 to 5, the addition of the stabilizer alcohol has a positive promoting effect on the cleaning effect of the foam cleaning agent, the addition of the cation and the increase of the alkali content can improve the cleaning effect, and other components have no obvious effect.

Temperature stability Performance detection

The temperature stability tests of examples 17-19, comparative examples 4-8 and imported alkaline foam cleaning agents of certain brands are carried out, wall hanging time detection and cleaning conditions on the surface of acrylic are respectively carried out at different temperatures, and the obtained data are shown in table 2;

TABLE 2 foam wall hanging at different temperatures

As can be seen from Table 2, by comparing examples 17-19 with comparative examples 4 and 5, it can be seen that the long-chain carbon alcohol stabilizer of the present invention has a longer wall hanging time and better cleaning effect on equipment at a higher temperature of 30-45 ℃.

In addition, through comparing examples 17-19 with comparative examples 5-8, the long-chain carbon alcohol disclosed by the invention has better stability at higher temperature (above 30 ℃) for a foam cleaning agent, and compared with the conventional added small-molecule alcohol, the long-chain carbon alcohol has better stability effect and longer wall hanging time.

Wall built-up time test

Referring to fig. 1-12, wall built performance tests were conducted on an alkaline foam cleaning agent of example 19 of the present invention with existing cleaning agent races 1,2, 3 and 4, wherein race 1 was an existing uk famous imported brand, race 2 was an existing us famous imported brand, race 3 was an existing known imported brand at belgium, and race 4 was an existing known imported brand in the netherlands. The test results are shown in table 3:

TABLE 3 wall build-up comparison of alkaline foam cleaners to competitors at various times

In this case, the glass surface was naturally dried by foaming and spraying with a foaming gun after diluting the glass surface twice, and the result is shown in fig. 12.

As can be seen from table 3, fig. 1-12, several product properties of the alkaline foam cleaner of the present invention, article 1, article 2, article 3, and article 4 were compared, wherein:

foaming power: the invention has the advantages that the competitive products 4 are more than the alkaline foam cleaning agent, 1 are more than the competitive products 1, 3 are more than the competitive products 2;

wall hanging property: the wall-hanging property of the alkaline foam cleaning agent and the competitive product 1 is difficult to distinguish from the eye observation result in terms of the original liquid and the diluted half, the competitive product 1 is slightly better than the alkaline foam cleaning agent in terms of the eye observation coverage area, but the alkaline foam cleaning agent is better than the competitive product 1 in foaming property and foam coverage thickness; however, the wall-hanging property of the competitive product 1 and the alkaline foam cleaning agent is obviously superior to that of the competitive product 2; (in terms of the conditions of stock solution and diluted one time of foaming and spraying on the glass wall, the competitive product 1 and the alkaline foam cleaning agent of the invention use the same foaming gun to generate foam, and the competitive product 1 has more uniform foam on the glass wall surface). The initial foam of the competitive product 3 is rich, but after 3 minutes, a large area of conglomeration and sliding starts to occur, less foam remains after 5 minutes (as shown in figure 3), and after 10 minutes, only a water mark is left, so that the wall built-up performance of the competitive product 3 is poor. The initial foam of the competitive product 4 is rich, the competitive product begins to roll and slide after 10 minutes, a large amount of the competitive product slips after 15 minutes, the distribution is uneven, the competitive product is still uniformly distributed after 20 minutes, rich foam exists, and the wall hanging durability is better.

Dilute 6 times single foaming and spray glass wall-hanging nature comparison: the alkaline foam cleaning agent of the present invention is superior to the competitive product 1.

After the glass surface is diluted twice and sprayed with foam by a foam gun, the glass surface is naturally dried, and residual traces are remained after the observation of the experimental result.
