[0052] 6) The polished scented beads were placed in an oven and baked at 60° C. for 12 hours to obtain waterproof Chinese herbal scented beads, whose water contact angle was 120°. After wearing for one month, the water contact angle was 118°.

[0053] Example 3

[0054] 1) 100g of Chinese herbal medicine powder prepared according to the rose fragrance recipe was mixed with 20g of 2,4-tolyl biscarbamic acid (perfluorobutyl ethyl, stearyl) ester and then ground through a 100-mesh sieve;

[0055] 2) Add 25g sticky powder and 110g water, use a medicine mill to pound the powder into a ball, beat and knead repeatedly until it becomes a uniform mud, then wrap it with plastic wrap and place it in a cool place to let it rise for 2 hours for later use;

[0056] 3) Roll the fragrant mud into a round shape and put it into the fragrant bead mold coated with release agent, compact it, remove the mold, and scrape off the excess part with a utility knife;

[0057] 4) Place the demoulded scented beads in a dark, dry, ventilated place to dry in the shade, and turn them over repeatedly;

[0058] 5) After hollowing out along the axis, grinding and polishing are performed to make the incense beads;

[0059] 6) The polished scented beads were placed in an oven and baked at 60°C for 12 hours to obtain waterproof Chinese herbal scented beads, whose water contact angle was 116°. After wearing for one month, the water contact angle was 115°.

[0060] Comparative Example 1

[0061] The preparation method of the scented beads provided in this comparative example is basically the same as that of Example 2, except that no waterproofing agent is added. The water contact angle is 74°, and the water contact angle is 75° after wearing for one month.

[0062] Comparative Example 2

[0063] The preparation method of the scented beads provided in this comparative example is basically the same as that of Example 2, except that the scented beads do not undergo an oven baking process after polishing, and the water contact angle thereof is 76°, and the water contact angle is 83° after being worn for one month.

[0064] Comparative Example 3

[0065] The preparation method of the scented beads provided in this comparative example is basically the same as that of Example 2, except that the waterproofing agent is not added at the initial mud mixing stage, but is applied to the surface of the scented beads after polishing. The water contact angle is 119°, and the water contact angle is 102° after wearing for one month.

[0066] Comparative Example 4

[0067] The preparation method of the scented beads provided in this comparative example is basically the same as that of Example 2, except that no waterproofing agent is added, and a beeswax protective layer is applied after the scented beads are polished. The water contact angle is 88°, and the water contact angle is 78° after wearing for one month.

[0068] It can be seen from the above results that after the introduction of the waterproofing agent, the waterproofing effect of the fragrance beads is greatly improved. Compared with the fragrance beads without adding the waterproofing agent (Comparative Example 1), the water contact angle of the fragrance beads prepared in Example 2 is increased from 74° to 120°, achieving a super-hydrophobic effect. Compared with the fragrance beads coated with a beeswax protective layer in the existing process (Comparative Example 4), the water contact angle still has obvious advantages. In order to better compare the waterproofing effect of the fragrance beads, the fragrance beads prepared in Example 2 and Comparative Example 4 were put into water at the same time. The results are shown in the attached figure. Figure 2 As shown, the combined fragrance beads of comparative example 4 sank to the bottom of the water, while the combined fragrance beads of example 2 floated on the water surface. This is because water cannot penetrate the surface of the combined fragrance beads of example 2, forming many small bubbles, causing them to float. This result intuitively proves the excellent waterproof effect of the combined fragrance beads of example 2.

[0069] By comparing Example 2 with Comparative Example 2, it can be seen that the final baking process is the key step for the waterproofing agent to migrate to the surface of the fragrance beads to form a super hydrophobic layer, and by comparing Example 2 with Comparative Example 3, this step can enhance the interfacial interaction between the waterproofing agent and the fragrance beads, thereby achieving a lasting waterproof effect.
