Here, the hydrated state may be slightly polarized in a polar solution state, such as slightly positive or slightly negative, and the ionic state is a state in which a functional group is obtained by obtaining or losing hydrogen, such as COOH group is obtained by losing hydrogen, so that the molecule in the hydrated state or ionic state may be reacted, polymerized and crosslinked, but the present invention is not limited thereto. Further, the random polymer is a polymer in which two structural units A and B appear at random as shown in the following formula (3), and the block polymer is a polymer composed of a long segment having only the structural unit A and a long segment having only the structural unit B as shown in the following formula (4).
Formula (3)
-A-B-B-B-A-B-A-B-A-A- (3)。
Formula (4)
-B-B-B-B-B-A-A-A-A-A-(4)。
It should be noted that the viscosity and pH of the ionic copolymer are not limited in the present invention, and can be determined according to the actual design requirements.
In some embodiments, the acrylic polymer has a molecular weight of 106To 109But the present invention is not limited thereto.
In some embodiments, the acryl-based polymer includes 2-Acrylamido-2-methylpropanesulfonic acid copolymer (2-acrylamidodo-2-methyl-propane sulfonic acid copolymer), Ethyl-2-Acrylamido-2-methylpropanesulfonic acid copolymer (Ethyl-2-acrylamidodo-2-methylpropanesulfonic acid copolymer), 2-Acrylamido-2, 3-methylpropanesulfonic acid copolymer (2-acrylamidodo-2, 3-methyl-propane sulfonic acid copolymer), or Poly [ 2-acrylamidodo-2-methylpropanesulfonic acid-co-propylene ] (Poly [ 2-acrylamidodo-2-methylpropanesulfonic acid-co-propylene ]), but the present invention is not limited thereto.
In some embodiments, the weight ratio of the acrylic polymer to the emulsifier is between 50% and 100%.
In summary, the emulsifier of the present invention achieves the conditions of optimizing the emulsification range, acid-base tolerance and consistency range by using the acrylic polymer comprising carbomer, ionic copolymer or a combination thereof, thereby having advantages in emulsification. Furthermore, as the lecithin and the acrylic polymer used in the emulsifier are in powder form, compared with the traditional aqueous solution acrylic emulsifier, the emulsifier of the invention has the advantages of convenient use and lower carbon emission in production, manufacture, transportation and storage, can solve the problem of layering and precipitation of the water-containing liquid acrylic emulsifier for a long time, and ensures that the product manufactured by the emulsifier can be maintained in a high-quality state every time. In addition, the use of lecithin can effectively improve the permeability of the emulsifier. On the other hand, the emulsifier of the present invention is effective in improving the condition of rich hands when mixed with alcohol.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
