Problems solved by technology

In view of the limitation of the specificity of cleaning agents, in practical applications, when some items need to be cleaned, no suitable cleaning agent can be found, which brings troubles to people
[0004] On the other hand, some cleaning agents that are too alkaline may damage the surface and make the surface lose its luster; the phenomenon of surface discoloration and surface cracking also occurs from time to time
Some cleaning agents that do not clean the surface of the object often have strong foaming power and rich foam, are not easy to rinse, and tend to remain, so they are not suitable for surface cleaning

Embodiment 1

[0038] Synthesis of threonine anionic surfactant modified by palmityl alcohol

[0039]

[0040] Step 1: Add 112g of itaconic anhydride and 242g of palmitic alcohol into a 1-liter flask, slowly raise the temperature to 70 degrees Celsius, and keep the temperature within the range of 70 to 75 degrees Celsius. After the itaconic anhydride is completely dissolved, continue to heat up to 95 degrees Celsius The reaction was carried out for 8 hours under stirring, and palmitic acid monoester could be obtained after cooling.

[0041] Step 2: Add 60 g of threonine and 40 g of sodium hydroxide into 500 ml of water, stir and dissolve completely, heat to 45 degrees Celsius, dissolve 177 g of itaconate palmitate monoester obtained in step 1 in 400 ml of ethanol, stir Slowly add dropwise to the above solution, keep the dropwise addition time for 1-1.5 hours, after the dropwise addition, continue to keep the temperature for 6 hours for reaction. The reaction solution was cooled to 0 degr...

Embodiment 2

[0044] Synthesis of palmityl alcohol modified glycine anionic surfactant

[0045]

[0046] Step 1: Consistent with Step 1 of Example 1.

[0047] Step 2: Add 37.6g of glycine and 40g of sodium hydroxide into 500 milliliters of water, stir and dissolve completely, heat to 45 degrees Celsius, dissolve 177g of palmitic monoester itaconate obtained in step 1 in 400 milliliters of ethanol, stir slowly Slowly add it dropwise to the above solution, keep the dropwise addition time for 1-1.5 hours, after the dropwise addition, continue to keep the temperature for 6 hours reaction. The reaction solution was cooled to 0 degrees Celsius with an ice-water cooling bath, filtered, and the solid was washed 2-3 times with 250 milliliters of ice ethanol, and the solid was put into a vacuum oven for drying at 60 degrees Celsius to obtain 185 g of palmityl alcohol-modified threonyl anionic surfactant.

[0048] The HLB value of palmityl alcohol-modified glycine anionic surfactant was calculated...

Embodiment 3

[0050] Table 1 below shows the component ratios (mass percentages) of the six formulations of the alkaline multi-surface cleaning agent.

[0051] Table 1:

Abstract

The invention discloses an alkaline multi-surface cleaning agent which is composed of the following components in percentage by mass: 5-10% of modified natural oil, 3-5% of a modified amino acid anionic surfactant, 1-2% of short-chain alkyl glycoside, 3-5% of sorbitol and 0.3-0.5% of a chelating agent. water is added to 100%. The alkaline multi-surface cleaning agent is green, free of pollution, easy to biodegrade, suitable for surfaces of different materials, high in dirt-removing power, low in foam, easy to rinse, free of damage to the surface of an object and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an alkaline multi-surface cleaning agent. Background technique [0002] In recent years, with the change of life pattern, the renewal of surface materials and the improvement of public environmental protection awareness, higher requirements have been put forward for surface cleaners for civil, commercial and industrial use. [0003] Common surface cleaners are mostly cleaners for a specific material, such as glass cleaners, wooden floor cleaners, stainless steel, ceramic and marble cleaners, etc. These cleaners are not universal and only suitable for a certain scene Or use a specific material. In view of the limitation of the specificity of cleaning agents, in practical applications, when some items need to be cleaned, no suitable cleaning agent can be found, which brings troubles to people. [0004] On the other hand, some cleaning agents that are too alkaline may dama...
