The invention discloses a preparation method of a fluorosiloxane hydrophobic modified blended fragrant product, which comprises the following steps: 1) mixing fragrant
powder in proportion, soaking the mixed fragrant
powder in a fluorosiloxane solution, filtering and
drying the fragrant
powder; (2)
grinding and sieving the modified spice powder, mixing with the sticky powder and the water according to a certain ratio, repeatedly plastifying into uniform mud by using an open mill, and fermenting the mud for later use; (3) pressing the fermented fragrant mud into sheets through an open mill, compacting the sheets in a mold, drawing the mold, and scraping off redundant parts; (4) putting the demolded blended fragrant product in a dark, dry and ventilated place for
drying in the shade; and 5)
grinding,
polishing and oiling to obtain the hydrophobic modified blended perfume. According to the invention, a low-surface-energy
fluorine element is introduced into the surface of the blended incense by utilizing a
chemical coupling reaction between the fluorosiloxane /
coupling agent and the incense powder, so that the hydrophobicity of the blended incense is improved, the
hydrophobic effect of the blended incense is remarkably improved, the problem that the blended incense is sticky and greasy in hand feeling caused by an additive type hydrophobic agent is avoided, and the service life of the blended incense is prolonged. The method is suitable for
moisture-proof and
mildew-proof treatment of high-value synthetic aromatic beads.
