(1.1) Synthesis of a Silicone prepolymer: adding an organosilicon monomer into alcohol (the volume ratio of water to the alcohol is 1:2.0), wherein the organosilicon monomer comprises dimethyl dimethoxy silane, 3- (methacryloyloxy) propyl trimethoxy silane and tetraethoxy silane with the mass ratio of 3.3:3.5:1, the mass volume ratio of the organosilicon monomer to the alcohol is 1g:3mL, adding 6mol/L hydrochloric acid to adjust the pH to 3, and carrying out reflux reaction for 2 hours at 90 ℃ to obtain an organosilicon prepolymer dispersion;
(1.2) coating toner: diluting the organosilicon prepolymer dispersion liquid with alcohol (the volume ratio of water to the alcohol is 1:2.0) for 8 times, adding toner and catechin, wherein the mass volume ratio of the catechin, the toner and the organosilicon prepolymer dispersion liquid is 1g:2.5g:8mL, stirring and reacting for 4 hours at room temperature after uniform dispersion, centrifugally separating, washing the precipitate with water and the alcohol in sequence, and drying to obtain toner@organosilicon prepolymer particles;
(1.3) grafting catechol groups: dispersing toner@organic silicon prepolymer particles into water, adding dopamine, wherein the mass volume ratio of the dopamine to the toner@organic silicon prepolymer particles to the water is 1g:3g:10mL, after uniformly mixing, dropwise adding 1.0mol/L sodium hydroxide solution under stirring to adjust the pH to 11, after dropwise adding for 40min, stirring and reacting for 5h at 80 ℃, centrifuging, separating, washing with water, and drying to obtain the toner@high-adhesiveness coating particles.
Comparative example 1
The difference between this comparative example and example 4 is only that in this comparative example, catechin was not added in step (1.2) when coating modification was performed on the toner, i.e., no antioxidant was grafted to the toner @ high adhesion coated particles.
Comparative example 2
The present comparative example differs from example 4 only in that in the present comparative example, step (1.3) was not performed when coating modification was performed on the toner, i.e., no collar xylenol group was grafted in the toner @ high-adhesion coated particle.
Comparative example 3
The present comparative example differs from example 4 only in that in the present comparative example, the coating modification includes the steps of:
(1.1) Synthesis of a Silicone prepolymer: adding an organosilicon monomer into alcohol (the volume ratio of water to the alcohol is 1:1.5), wherein the organosilicon monomer comprises dimethyl dimethoxy silane, 3- (methacryloyloxy) propyl trimethoxy silane and tetraethoxy silane with the mass ratio of 2.3:5.5:1, the mass volume ratio of the organosilicon monomer to the alcohol is 1g:6mL, adding 5mol/L hydrochloric acid to adjust the pH to 5, and carrying out reflux reaction for 3 hours at 80 ℃ to obtain an organosilicon prepolymer dispersion;
(1.2) grafting catechol groups: adding dopamine into the organosilicon prepolymer dispersion liquid, wherein the mass volume ratio of the dopamine to the organosilicon prepolymer dispersion liquid is 1 g/9 mL, after uniform mixing, dropwise adding 0.5mol/L sodium hydroxide solution to adjust the pH to 9 under stirring, after dropwise adding for 30min, stirring and reacting for 6h at 70 ℃, and then adding 5mol/L hydrochloric acid to adjust the pH to 5, thus obtaining modified organosilicon prepolymer dispersion liquid;
and (1.3) adding toner and catechin into the modified organosilicon prepolymer dispersion liquid, wherein the mass volume ratio of the catechin to the toner to the modified organosilicon prepolymer dispersion liquid is 1g:1.5g:24mL, stirring and reacting for 3 hours at room temperature after uniform dispersion, centrifugally separating, washing the precipitate with water and ethanol in sequence, and drying to obtain the toner@high-adhesion coating particles.
Test case
Eyebrow pencil leads of examples 1 to 5 and comparative examples 1 to 3 were manufactured into eyebrow pencil, and after one year of storage, skin test was performed as follows:
(1) Uniformly smearing a coating block with the same depth and the width and about 1cm and about 3cm on the arm of each volunteer by using an eyebrow pencil, rubbing with fingers for 3 times along the length direction, observing the rubbing condition, scoring the rubbing resistance of the eyebrow pencil according to the rubbing condition, wherein 9-10 points indicate no obvious rubbing phenomenon, 4-9 points (without 9 points) indicate obvious rubbing phenomenon, and 0-4 points (without 4 points) indicate almost complete rubbing; volunteers were 10 women aged 20-40 years and scores averaged;
(2) The eyebrow pencil is smeared on the eyebrows of volunteers, makeup removal is observed after 4 hours and 8 hours, the makeup applying duration of the eyebrow pencil is scored according to the makeup removal, no obvious lightening and rarefaction phenomenon is shown in 9-10 points, the lightening and rarefaction phenomenon is obvious in 4-9 points (excluding 9 points), and almost complete makeup removal is shown in 0-4 points (excluding 4 points); volunteers were 10 women aged 20-40 years and scores were averaged.
The test results are shown in Table 5.
TABLE 5
Analyzing the data of Table 5, the following conclusions can be drawn:
(1) The apparent improvement in make-up durability and abrasion resistance of examples 4 and 5, compared to example 1, demonstrates that the make-up durability and abrasion resistance of the eyebrow pencil lead can be improved after the toner is coated by the method of the present invention.
(2) The reduced make-up durability and abrasion resistance of comparative example 1 compared to example 4 suggests that the make-up durability and abrasion resistance of the eyebrow pencil lead can be improved by grafting catechin to the silicone polymer coating. The reason is that: by grafting an antioxidant onto the silicone polymer, the reduction in adhesion caused by oxidation of the benzene diphenol groups during storage of the adjacent eyebrow pencil can be slowed down, thereby improving the durability and anti-friction properties of the make-up.
(3) The decrease in make-up durability and abrasion resistance of comparative example 2 compared to example 4 suggests that the make-up durability and abrasion resistance of the eyebrow pencil lead can be improved by grafting dopamine on the surface of the silicone polymer coating. The reason is that: the organosilicon polymer has better adhesiveness on the skin surface, and the adhesiveness of the coating layer can be further improved by grafting catechol groups, so that the durability and the friction resistance of make-up are improved.
(4) Compared with example 4, the dressing durability and the rubbing resistance of comparative example 3 are reduced, and the method of coating and grafting firstly is adopted to improve the dressing durability and the rubbing resistance of the eyebrow pencil lead compared with the method of grafting dopamine on the organosilicon prepolymer and coating the toner. The reason is that: if the grafting-coating mode is adopted, catechol groups are easy to be combined to the surface of the toner through complexation and other modes, the catechol groups on the surface of the coating layer are reduced, and the improvement effect on the adhesive force is limited.
The raw materials and equipment used in the invention are common raw materials and equipment in the field unless specified otherwise; the methods used in the present invention are conventional in the art unless otherwise specified.
The foregoing description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any simple modification, variation and equivalent transformation of the above embodiment according to the technical substance of the present invention still fall within the scope of the technical solution of the present invention.
