Description

Method of making gypsum air freshener

The present invention relates to a method for producing a gypsum fragrance, and more particularly, to a method for producing a gypsum fragrance capable of improving the quality of the gypsum fragrance by mixing gypsum powder and a pigment to form a powder material.

A commonly used fragrance is a product that causes the fragrance to emit by repeatedly adsorbing the fragrance on a porous material over a predetermined number of times as the fragrance is exhausted after a certain period of time and cannot emit fragrance.

Specific examples of these products include gypsum fragrance, which is formed into various shapes by mixing water, oil, emulsifier, and dye with gypsum, and absorbs the desired fragrance into the molded gypsum to emit fragrance. When this is exhausted, the fragrance is replenished so that the fragrance is released again, and at the same time, the visual beauty is felt.

However, since a large amount of air bubbles are generated during molding, the gypsum fragrance has a problem that the surface is not smooth, the strength is not good, and the molded product is damaged even with a small impact. In addition, there is also a disadvantage of severe powder blowing.

In order to improve these disadvantages, Korean Patent Laid-Open No. 10-2015-0144023 proposes a method of making the gypsum powder tough by using hwaseonji liquid together with gypsum powder.

In addition, Korean Patent Application Publication No. 10-2016-0107732 proposes a method of increasing the strength of a gypsum fragrance by mixing Korean paper with gypsum powder.

However, even if there is no additional substance, gypsum powder has a smooth surface with improved strength when the amount of liquid material is reduced and the amount of air bubbles is reduced.Therefore, a method of reducing the amount of liquid used in any of the preceding documents has been proposed. There was no bar.

Accordingly, an object of the present invention is to solve the problems of the conventional gypsum fragrance, and to provide a method for producing a gypsum fragrance having excellent strength and improved durability by mixing a pigment with gypsum powder.

Another object of the present invention is to provide a method for producing a gypsum fragrance having excellent quality due to the use of the pigment to reduce the use of the liquid material as a whole, so that there is no bubble generation, so that the surface is smooth and there is little dust.

The problem to be solved by the present invention is not limited to the ones mentioned above, and another problem to be solved that is not mentioned can be clearly understood by those of ordinary skill in the art from the following descriptions. will be.

1 is a manufacturing process diagram of a gypsum fragrance according to an embodiment of the present invention.

A method for producing a gypsum fragrance according to an embodiment of the present invention comprises the steps of preparing a powder material by mixing gypsum powder and a pigment; Mixing a liquid material with the powder material; Injecting the mixed mixture into a mold and curing; And it may include the step of demoulding the cured cured product.

Hereinafter, the present invention will be described in detail.

The biggest feature of the present invention is that the pigment is mixed with gypsum powder and used as a powder material, thereby reducing the overall amount of liquid material, as well as improving the strength, reducing powder blowing, and reducing the occurrence of air bubbles to smooth the surface. , In expressing beautiful colors.

First, a method for producing a gypsum fragrance according to the present invention will be described in detail with reference to FIG. 1.

The method for producing a gypsum fragrance according to the present invention includes preparing a powder material by mixing gypsum powder and a pigment, mixing a liquid material including water and an emulsifier into the powder material, and molding the mixed mixture. Into and curing, and demolding the cured cured product, wherein the pigment is any one of an inorganic pigment and an organic pigment.

Preparing a powder material by mixing gypsum powder and pigment.

First, a powder material is prepared by mixing gypsum powder and a pigment.

Here, the type of gypsum powder is not limited, but at least one of medical gypsum powder and molding gypsum powder may be used, and preferably, medical gypsum powder, medical gypsum powder and molding gypsum powder are 1:0.5~1.5 weight ratio. It is to use the mixture. This is because the medical gypsum powder has a small powder particle and a small amount of mixed water, so that the powder is less scattered or smeared compared to the molding gypsum powder. In addition, compared to the case of using only the medical gypsum powder, when it is mixed with the molding gypsum powder, there is an advantage in that rapid curing and excellent color expression are possible.

The pigment not only expresses the color of the gypsum fragrance through the coloring of the gypsum powder, but also reduces the amount of liquid material used, thereby improving overall strength and durability, and reducing powder scatter. It also prevents discoloration of the plaster fragrance. The pigment not only enables the use of the dye, which is a liquid material, to be omitted, but also reduces the amount of mixed water by relatively reducing the amount of gypsum powder used, so that the total amount of the liquid material can be reduced.

As the pigment, at least one of inorganic pigments, organic pigments, and mixtures thereof, that is, various types of conventionally published ones may be used, for example, titanium dioxide, zinc oxide, yellow iron oxide, red iron oxide, black iron oxide, phthalocyanine blue , Ultramarine Blue, Ultramarine Pink, Ultramarine Violet, chromium oxide green, phthalocyanine blue, phthalocyanine green, and at least one of carbon black may be used. In addition, it is natural that, in addition to these types, any pigments in powder form can be used without limiting their types.

In the present invention, the mixing ratio of the gypsum powder and the pigment is preferable to mix 1 to 20 parts by weight of the pigment with respect to 100 parts by weight of the gypsum powder. When the amount of the pigment is small, its role is negligible, such as increasing strength and expressing color. This is because the action effect is insignificant, and if excessive, the scent smell can be relatively reduced.

Hereinafter,'parts by weight' in the present invention is based on 100 parts by weight of the gypsum powder.

Mixing a liquid material including water and an emulsifier with the powder material.

Next, a liquid material containing water and an emulsifier is mixed with the prepared powder material.

Here, the emulsifier is for stable dispersion of the pigment, and olive liquid, which is an ingredient safe for the human body, may be used, but this is not necessarily limited. The emulsifier can be used in an amount of 3 to 13 parts by weight, based on 100 parts by weight of gypsum powder, which is one of the powder materials. If the amount is too small, it is difficult to uniformly disperse the pigment, and if the amount is excessive, the overall physical properties decrease. .

In addition, the water is for hardening of the gypsum powder, and it is preferable to use water at room temperature or lukewarm water. Here, the amount of water is determined according to the amount of mixed water of the gypsum powder, and may be generally 20 to 35 parts by weight based on 100 parts by weight of the gypsum powder.

In addition, as the liquid material, at least one of fragrance oil and dye may be further included as necessary.

The fragrance oil is an ingredient for scenting, and any of natural essential oils (E.O) as well as fragrance oils (F.O) can be used, and the use thereof is omitted if it is to be used as a post-addition type. At this time, the fragrance oil can be mixed in the range of 3 to 6 parts by weight, because if the amount is too small, the fragrance smell is not good, and if the amount is excessive, the strength and durability of the gypsum fragrance decrease, which makes handling difficult.

In addition, the dye is a component representing the color of the gypsum fragrance together with the pigment, and may be added in a small amount if necessary, but it is natural that it can be omitted. The dye is preferably used in the range of 1 to 5 parts by weight.

Here, after mixing all of the liquid materials, the powder material and the liquid material may be mixed, or water is added to the powder material to mix, and then a fragrance oil and an emulsifier are added to mix, and a dye is added again. It can also be mixed, and the order of addition of the liquid material is not limited.

Injecting the mixed mixture into a mold and curing.

Next, the mixed mixture is put into a mold and cured.

Here, the type of the mold is not limited, and since the injection method and curing are performed according to a generally known method, a detailed description thereof will be omitted.

Demoulding the cured cured product.

Then, the cured product is demolded from the mold to complete the manufacture of the gypsum fragrance.

In addition, in the present invention, the pigment may be prepared and used in a liquid state, and its implementation is not limited.

The method of preparing the pigment in a liquid state is to mix water and a pigment, mix it with an emulsifier, and then aged at 10 to 30°C for 20 to 40 hours, and when the precipitate settles to some extent, only the liquid phase excluding the settled precipitate is used. will be. In this case, the amount of water, pigment, and emulsifier used is preferably about a weight ratio of 1:0.8 to 1:0.3 to 0.8, but the amount of water and emulsifier used when preparing the pigment in liquid form is the total amount used in the manufacture of gypsum fragrance. By excluding it from the amount used, the final amount is not changed.

And the gypsum fragrance according to the present invention, a powder material comprising a gypsum powder and a pigment; And a liquid material including water and an emulsifier.

At this time, as described above, based on 100 parts by weight of the gypsum powder, the pigment is included in the range of 1 to 20 parts by weight, the emulsifier is included in the range of 3 to 13 parts by weight, and fragrance oils and dyes that can be selectively used as the liquid material It can be used in a range of 3 to 6 parts by weight of a fragrance oil and 1 to 5 parts by weight of a dye.

In addition, the gypsum powder is any one of medical gypsum powder, molding gypsum powder, and mixtures thereof, and the pigment is titanium dioxide, zinc oxide, yellow iron oxide, red iron oxide, black iron oxide, phthalocyanine blue, ultramarine blue, ultramarine pink , Ultramarine violet, chromium oxide green, phthalocyanine blue, phthalocyanine green, and carbon black.

As described above, the gypsum fragrance prepared as described above has advantages in that it has excellent strength and durability, less scattering and smearing of powder, and excellent color expression. In addition, there is also the advantage of less discoloration due to the application of the pigment.

Meanwhile, the present invention may further include 1 to 3 parts by weight of liquid paraffin as a liquid material. In the step of mixing the liquid material with the powder material, 1 to 3 parts by weight of liquid paraffin is additionally mixed.

The liquid paraffin (Liquid Paraffin) plays a role of suppressing the powder spreading and smearing of the gypsum fragrance. If the amount is too small, the effect is insignificant, and if the amount is excessive, the overall quality as a fragrance is deteriorated. Mix within.

In addition, the present invention may further include 1 to 5 parts by weight of talc as a powder material, and 1 to 5 parts by weight of talc is mixed in the step of mixing the pigment with the gypsum powder.

The talc (Talc) serves to smooth the surface of the gypsum fragrance and to increase the strength.If the amount is too small, the effect is insignificant, and if the amount is excessive, the quality as a fragrance is deteriorated. Mix within.
