Incense core and preparation method thereof

Abstract

The invention aims to provide an incense core and a preparation method thereof so as to satisfy the demand that the incense core used by the user is great in perfume adsorption and long in service life. The incense core provided by the invention comprises an incense core matrix which adsorbs oily perfume. The key point is that an oil-dispelling hydrophilic coating film with ventilating holes is wrapped on the surface of the incense core matrix. The oil-dispelling hydrophilic coating film can effectively prevent oily perfume from permeation on the surface of the incense core and makes the oily perfume adsorbed by the incense core be diffused from the ventilating holes of the coating film, so that the diffusing speed is alleviated and the perfume can be used for a relative long time. The incense core is wrapped by the coating film where perfume cannot permeate, so that the volatilization speed of the perfume is delayed, the volatilization speed of the perfume is more uniform, the service life of the perfume is effectively prolonged, the concentration of the perfume in a vehicle can be maintained over a certain numerical value within the whole service cycle of the perfume, and the using experience of passengers is improved.

Description

technical field [0001] The invention belongs to the technical field of perfume manufacturing, and in particular relates to a fragrance core and a manufacturing method thereof. Background technique [0002] The solid incense core has the advantages of being easy to shape and not being spilled due to car bumps. Many car perfumes have used solid incense cores instead of liquid perfumes. At present, there are the following types of solid incense cores: 1. Thick cotton paper type: directly use thick cotton paper to make different shapes according to requirements, and use the water absorption characteristics of the fibers in the tissue paper to absorb perfume. The disadvantage of this kind of incense core is that the material is too large. Soft, the perfume is not firmly adsorbed, it is easy to volatilize, and the use time is short; 2. Wood type: directly use soft wood to make wooden beads or blocks to absorb perfume. The disadvantage of this kind of incense core is that the perf...

Problems solved by technology

At present, there are the following types of solid incense cores: 1. Thick cotton paper type: directly use thick cotton paper to make different shapes according to requirements, and use the water absorption characteristics of the fibers in the tissue paper to absorb perfume. The disadvantage of this kind of incense core is that the material is too large. Soft, the perfume is not firmly adsorbed, it is easy to volatilize, and the use time is short; 2. Wood type: directly use soft wood to make wooden beads or blocks to absorb perfume. The disadvantage of this kind of incense core is that the perfume has less adsorption and insufficient aroma. ;3. Porous plastic type: the plastic with countless micropores inside is made of resin as the main raw material, cut into various shapes according to requirements, and uses the micropores in the plastic to absorb perfume

The disadvantage of this kind of incense core is that the material itself has no adsorption force for perfume, and the amount of perfume absorbed is small. The perfume infiltrated into the micropores is easy to volatilize, the fragrance is insufficient, and the use time is short; 4. Inorganic salt type: use diatoms or Gypsum inorganic salt is the main raw material, which is formed by adding water and pressing, and then dehydrated and dried to absorb perfume

The disadvantage of this kind of incense core is that there are too few pores in the incense core, the amount of perfume absorbed is small, and the fragrance is insufficient.

The above-mentioned several kinds of solid incense cores cannot meet the user's requirements for a large amount of perfume adsorption and a long service time of the incense core.
