Description

Foam cleaning agent easy to rinse and preparation method thereof

Technical Field

The invention relates to the field of cleaning agents, in particular to an easy-to-rinse foam cleaning agent and a preparation method thereof.

Background

Alkaline cleaners are mainly based on a combination of alkaline substances and surfactants. The surfactant generally has the function of high foam, the foam adsorbs stains, the cleaning is faster and more efficient, and the surfactant is mainly used for removing fat, protein and polysaccharide on hard surfaces.

Most of the surfactants adopted in the existing foam cleaning agent are anionic surfactants, nonionic surfactants and amphoteric surfactants which are singly or compositely combined. Such as publication number CN105925395A, publication number CN106497703A, CN106520399a, publication number CN112961739A, CN110079402a, etc. The foam cleaning agent mainly uses anionic surfactant, nonionic surfactant and amphoteric surfactant.

The cationic surfactant has excellent sterilization performance, can improve cleaning capability, and has better foaming performance, but because the cationic surfactant and the anionic surfactant are compounded to easily generate precipitation and lose surface activity, the existing cleaning agent with high-efficiency sterilization performance is mainly compounded with the cationic surfactant and the nonionic surfactant, and little cationic surfactant, anionic surfactant and nonionic surfactant are compounded for use. The technical scheme of the foam cleaning agent with the disinfection and cleaning functions disclosed in the publication No. CN111440676A is that a cationic surfactant, an anionic surfactant, a nonionic surfactant, organic amine and small molecular alcohols of C1-C4 are compounded, and although the disinfection performance can be improved, the organic amine is mainly alcohol amine and is used as a rust remover, and meanwhile, the small molecular alcohols of C1-C4 are mainly used as a solution stabilizer. The technical scheme of the foam cleaning agent with long-acting wall built-up property disclosed in publication No. CN115806861A is that an anionic surfactant, a cationic surfactant and long carbon alcohol are compounded, and the technical problem to be solved is the wall built-up property of foam. The technical scheme of the acidic foam cleaning agent applied to the water curtain of the pig farm disclosed by publication No. CN115806862A is that the acidic foam cleaning agent is obtained by combining an acidic component, an anionic surfactant, a cationic surfactant, a nonionic surfactant and a stabilizer (long carbon alcohol), and the technical problems of cleaning effect and compatibility of the anionic surfactant and the cationic surfactant are solved. An alkaline foam cleaning agent and a preparation method thereof are disclosed in publication No. CN115806863A, the technical scheme is that the alkaline foam cleaning agent is obtained by combining alkaline substances, anionic surfactants, cationic surfactants, nonionic surfactants and stabilizers (long carbon alcohol), and the technical problem of foam wall-hanging property is solved.

The fatty acid and the surfactant are compounded to be used as a foam cleaning agent, and the liquid cleaning agent composition disclosed in publication No. CN1150173A adopts the technical scheme that the fatty acid, the anionic surfactant and the zwitterionic surfactant are compounded to obtain the foam cleaning agent, but the technical problem to be solved is to provide the cleaning agent with strong detergency, wetting and certain foaming. The liquid soap composition disclosed in publication No. CN103108946A adopts the technical scheme that fatty acid is compounded with anionic surfactant and nonionic surfactant, but the technical problem solved by the liquid soap composition is to improve the stability of fatty acid. The technical scheme of the cleaning composition disclosed in the publication No. CN115315244A is that the C10-C18 fatty acid is compounded with an anionic surfactant, a zwitterionic surfactant and an alcohol amine type, and the organic amine is mainly used as a stabilizer of foam although the organic amine is added, so that the technical problem solved by the whole technical scheme is the stability of the foam.

In summary, the conventional foam cleaning agent is mainly around the aspects of sterilization performance, solubility, foamability and environmental protection of materials, but because the foam cleaning agent can generate a large amount of foam, when the foam cleaning agent is washed by water after use, the foam floats on the water surface, so that the foam is difficult to foam, long-time and large-amount water washing is required, time and water are wasted, and especially in a large-scale use scene, the washing is not easy.

Foam Performance test

The cleaning agents obtained in examples 1 to 19 and comparative examples 1 to 20 were each prepared as a dilution liquid having a concentration of 1% by mass, and the appearance state, foam height and surface tension of each group of the dilutions were observed, and the results obtained are shown in table 1:

table 1 foam performance data for each group

As can be seen from Table 1, the surface tension of the cleaning agents obtained in examples 1 to 19 is between 20 and 25mN/m, the surface tension is low, the surface activity of the whole cleaning agent is greatly improved, and the cleaning ability, the sterilization ability and the foam performance are all greatly improved.

The components of the comparative example 1 and the comparative example 2 do not contain dimethyl propylene diamine, and the obtained cleaning agent has spherical micelle form; the double-layered micelle has stronger capability of attracting reaction ions, low surface tension and better cleaning effect. The conventional alcohol amine is added in the comparative example 2 and the comparative example 3, the micelle state is changed from a spherical state to a bilayer, but compared with the example 7, the surface tension of the comparative example 2 and the comparative example 3 is increased, and particularly the half-life time of the foam is shorter, the foam stability is poorer, the wall-hanging time of the foam is shorter, and the long-term cleaning purpose cannot be achieved.

The alcohols in comparative examples 5 to 10 are short carbon alcohols, the comparative examples 11 to 12 are long carbon fatty alcohols with more than 18 carbon atoms, the cleaning agents in comparative examples 5 to 12 are all spherical in micelle state, and compared with example 7, although the surface tension is lower, the half-life time of the foam is shorter, the foam stability is poorer, the wall-hanging time of the foam is shorter, and the long-term cleaning purpose still cannot be achieved.

The anionic surfactant is added in comparative example 13 and comparative example 14, while the nonionic surfactant is added in comparative example 15 and comparative example 16, and the addition of the anionic surfactant and the nonionic surfactant can greatly reduce the surface activity, so that the foam has higher height, shorter half-life period of the foam and poorer stability of the foam, and the long-term cleaning purpose cannot be achieved.

In comparative example 17, dodecanol and organic amine were not added; in comparative example 18, no potassium hydroxide was added; in comparative example 19, in which potassium hydroxide and dodecanol were not added, the micelle state was also clearly distinguished, and the half life of the foam was short.

From the comprehensive data of examples 7 and comparative examples 1-19, the fatty acid is used as a main cleaning and foaming substance, and is specifically compatible with organic amine dimethyl propylene diamine, potassium hydroxide, long carbon alcohol and cationic surfactant, and the fatty acid and the cationic surfactant cooperate to form a double-molecular-layer micelle of the cleaning agent, so that the foam stability is enhanced, the surface tension of a double-molecular-layer structure system is lower, the surface activity is enhanced, the 1% half-life time of the foam is longer, the wall hanging property is better, the action time of the foam on a hard surface is longer, and the cleaning is more thorough.

Whereas comparative example 20 differs from example 7 in the preparation method. The preparation method of the invention is to mix fatty acid with deprotonating agent and organic amine, adjust pH value to 8, and then add other substances. While comparative example 20 was a conventional direct mix, the pH was adjusted to 8, but comparative example 20 had poor foaming properties and poor foam stability, and was not able to be wall built up and cleaned effectively for a long period of time.

Cleaning effect test

The action object is as follows: the surface of the food processed Asian gram, the stainless steel wall surface and the greasy dirt glass wall surface of the pig farm;

sample: the cleaning agents obtained in example 7 and comparative examples 1 to 20 were diluted 100 times to obtain diluted solutions, respectively;

the experimental method comprises the following steps:

(1) Washing the hard surface with high-pressure water, washing the surface of the wall body with high-pressure water after 5min, and sampling and detecting data before foam cleaning of the sample with an ATP detector;

(2) Respectively spraying the sample on a hard surface by adopting foam, flushing the foam by using a high-pressure water gun after 20min, sampling and detecting the data after foam cleaning by using an ATP fluorescence detector on the same sampling point again, and testing the results as shown in Table 2;

TABLE 2 ATP detection data

As can be seen from Table 2, the cleaning effect of the cleaning agent of example 7 was better, and the cleaning effects of comparative examples 13 to 16 were better because the anionic surfactant and the nonionic surfactant were added thereto, and the other components were the same, so that the difference in cleaning effects was not large. From examples 7 and comparative examples 1 to 12, and comparative examples 17 to 19, it can be seen that the cleaning effect is better when the fatty acid is compounded with several organic amines of dimethylpropanediamine, potassium hydroxide and long carbon alcohol.

Rinse time and defoaming test

Test purpose: detecting defoaming time and water consumption of the cleaning agent after flushing;

test instrument: greasy dirt glass wall surface; respectively placing the greasy dirt glass wall surfaces in a container;

test sample: the cleaning agents obtained in examples 1, 7, 10, 11, 12, 13 and comparative examples 1 to 20 were diluted 100-fold to obtain diluted solutions, respectively;

the test method comprises the following steps: respectively spraying the sample on a hard surface by adopting foam, flushing the foam by using a high-pressure water gun after 5min, wherein the flushing time is 5s, detecting the foam height of the flushed waste water in a container, and measuring the foam height for 30s, 1min, 5min and 10min after each flushing, wherein the measured results are shown in table 3:
