Problems solved by technology

[0002] At present, there are many types of surfactants, but many low-foaming surfactants are not strong in cleaning power, and are easy to precipitate in the aqueous solution of alkaline additives, which greatly reduces the effect of cleaning agents, resulting in poor cleaning power, and It is easy to cause the surfactant to adhere to the object to be cleaned; while the surfactant with good cleaning power has the problem of too much foam, it is not easy to rinse when spraying and cleaning. Therefore, the existing technology needs to be perfected and developed

Embodiment 1

[0038] In the reactor, add 30 parts of fatty alcohol polyoxyethylene polyoxypropylene ether, 30 parts of tea saponin, 20 parts of fatty alcohol polyoxyethylene ether, 19 parts of Span S-80 and 1 part of cellulose; The rotating speed is 90 rpm, wherein the fatty alcohol polyoxyethylene ether is AE03 type, and the cellulose is carboxymethyl cellulose. Use 50% potassium hydroxide solution to adjust the pH value of the mixture in the reaction kettle to be constant at 6 to 8, while stirring continuously; after stirring evenly, heat to 110°C, and then fully react for 3 hours, and simultaneously distill off the water under reduced pressure, that is, Get the finished product. During the whole reaction process, the temperature is not lower than 40°C, otherwise it needs to be heated to between 40°C and 110°C.

Embodiment 2

[0040] Add 50.8 parts of fatty alcohol polyoxyethylene polyoxypropylene ether, 30 parts of tea saponin, 18 parts of fatty alcohol polyoxyethylene ether, 1 part of Span S-80 and 0.2 part of cellulose in the reactor; The rotating speed is 90 rpm, wherein the fatty alcohol polyoxyethylene ether is AE09 type, and the cellulose is carboxymethyl cellulose. Use 50% potassium hydroxide solution to adjust the pH value of the mixture in the reaction kettle to be constant at 6 to 8, while stirring continuously; after stirring evenly, heat to 110°C, and then fully react for 3 hours, and simultaneously distill off the water under reduced pressure, that is, Get the finished product. During the whole reaction process, the temperature is not lower than 40°C, otherwise it needs to be heated to between 40°C and 110°C.

Embodiment 3

[0042] In the reactor, add 64.85 parts of fatty alcohol polyoxyethylene polyoxypropylene ether, 25 parts of tea saponin, 0.1 part of fatty alcohol polyoxyethylene ether, 10 parts of Span S-80 and 0.05 part of cellulose; The rotating speed is 90 rpm, wherein the fatty alcohol polyoxyethylene ether is AE09 type, and the cellulose is ethyl cellulose. Use 50% potassium hydroxide solution to adjust the pH value of the mixture in the reaction kettle to be constant at 6 to 8, while stirring continuously; after stirring evenly, heat to 110°C, and then fully react for 3 hours, and simultaneously distill off the water under reduced pressure, that is, Get the finished product. During the whole reaction process, the temperature is not lower than 40°C, otherwise it needs to be heated to between 40°C and 110°C.

Abstract

The invention aims to provide a surfactant composite dedicated for spraying and low-foam cleaning and a preparation method thereof. The surfactant composite comprises the following components in parts by weight: 30-70 parts of fatty alcohol polyoxyethylene polyoxypropylene ether, 1-30 parts of tea saponin, 0.1-20 parts of fatty alcohol polyoxyethylene ether, 1-20 parts of Span S-80 and 0.01-1 part of cellulose. The surfactant composite has the advantages of low foam, good cleaning capability, and small possibility of dissolving out from alkaline solution, is easy to rinse, is environmentally friendly and is suitable for spraying and cleaning, and low-foam cleaning agent with good quality can be easily prepared by cooperating with cleaning accessory ingredients.

Description

technical field [0001] The invention relates to surfactants, in particular to a special surfactant composition for spray low-foam cleaning and a preparation method thereof. Background technique [0002] At present, there are many types of surfactants, but many low-foaming surfactants are not strong in cleaning power, and are easy to precipitate in the aqueous solution of alkaline additives, which greatly reduces the effect of cleaning agents, resulting in poor cleaning power, and It is easy to cause the surfactant to adhere to the object to be cleaned; while the surfactant with good cleaning power has the problem of too much foam, and it is not easy to rinse when spraying and cleaning. Therefore, the prior art needs to be perfected and developed. Contents of the invention [0003] The present invention aims to solve the above problems, and provides a special surfactant composition for spraying and low-foaming cleaning with strong cleaning power and low foaming and a prepar...
