Description

{Solid Maker With Erasuring and Water Solubility}

More particularly, the present invention relates to a marker which can be softly applied when writing or drawing on a non-absorbing surface such as a white board or the like, and can be easily erased using a cloth or the like The present invention relates to a marker having a water-solubility and high water-solubility, which can be easily erased even after a long time has elapsed without scarring.

Generally, chalk and board pen (marker pen) are usefully used when it is used repeatedly in school, school, home, office, etc., and solid chalk is widely used in schools and academies from past to present have.

However, when the solid chalks are handwritten, erased, cleaned, etc., dust is generated, thereby adversely affecting the health of the human body and causing many problems such as polluting the surrounding environment.

In order to solve the above problems, a water chalk (or liquid chalk) has been developed and used. However, since a separate dedicated blackboard must be provided, the cost is high and knocking operation is required, Problems such as generation of a small amount of dust after drying are exposed.

In addition to the above-mentioned water chalk, there is a marker pen used for a non-absorbent surface such as a white board. However, when the water is dried after a certain period of time after writing, etc., it is difficult to erase and a mark is likely to occur and a little dust is generated .

Disclosure of the Invention The present invention is to solve the problems of the conventional chalk or marker pen as described above, and it is an object of the present invention to provide a non-ionic surface active agent, which uses wax, nonionic surfactant, extender pigment, 8 to 13, and since the release agent is liquid paraffin and / or isopropyl myristate, since the application feeling is good and the dust is not scattered during the erasing, the marks are not removed and can be cleanly wiped off and wiped off with water And to provide a brittle solid shape marker having erasable water-solubility.

The brittle solid shape marker having water solubility proposed by the present invention comprises wax, nonionic surface active agent, extender pigment, exfoliating agent and coloring agent.

The wax is used as an excipient, and it is possible to use a wax which is generally widely used for holding a shape as a seedling fire like a conventional crayon.

Specific examples of the wax include carnauba wax, microcrystalline wax, montan wax, candelilla wax, paraffin wax, ketone wax, Fisher-Tropsch wax and the like.

When the wax is used in particular with a ketone wax or Fisher-Tropsch wax, good performance as an excipient can be exhibited.

The ketone wax and the Fisher-Tropsch wax may be used alone or in combination of two or more. One or more of the ketone wax and the Fisher-Tropsch wax may be selected.

When the ketone wax is used, it is possible to obtain an effect of improving the smashing and dispersing properties, and when Fisher-Tropsch wax is used in combination, it is possible to obtain an effect that the non-absorbing surface writing property and the smearing property are improved.

The ketone wax may be at least one selected from the group consisting of stearic acid, myristic acid and palmitic acid.

The wax is preferably used in an amount of about 10 to 50% by weight, and more preferably about 20 to 40% by weight.

When the wax is used in an amount of less than 10% by weight, it is difficult to form the solid into a solid state. When the wax is used in an amount exceeding 50% by weight, the application feeling and the erasing property are deteriorated.

The nonionic surfactant is added in order to impart brittleness and water solubility. It is liquid at room temperature and has a HLB (Hydrophilic Lipophilic Balance) value of about 8 to 13.

Examples of the nonionic surfactant include polyoxyethylene alkyl ether, polyoxyethylene alkyl ester, and the like.

When the nonionic surfactant is used at room temperature, it has a disadvantage in that erosion is deteriorated and compounding is not easy to use.

If the nonionic surfactant has an HLB value of less than 8, the erasability is good, but it is difficult to apply to the non-absorbing surface. If the HLB value is more than 13, compatibility with the wax is deteriorated. Occurs.

The nonionic surfactant is preferably used in an amount of about 5 to 40% by weight, and more preferably about 10 to 30% by weight.

When the nonionic surfactant is used in an amount of less than 5% by weight, the water solubility of the nonionic surfactant is lowered, and when the nonionic surfactant is used in an amount of more than 40% by weight, separation and spreading of the nonionic surfactant are increased.

The extender pigment is used for adjusting the viscosity of the molding and it is preferable to use talc, clay, calcium carbonate, barium sulfate, alumina, mica, boron nitride, starch, bentonite or the like widely used in crayons, crayons and colored pencils It is possible.

About 5 to 50% by weight of the extender pigment is used.

The exfoliating agent is used for improving the erosion resistance of the coating film written on the non-absorbing surface, and commonly used myristic acid esters such as isopropyl myristate, butyl myristate, ethyl palmitate, isopropyl palmitate, methyl stearate and butyl stearate Esters of fatty acids and aliphatic alcohols, liquid paraffin and the like having a boiling point of 200 ° C or higher are preferably used.

As the release agent in the above, it is preferable to use one of liquid paraffin and myristate isopropyl, or both, because it is excellent in peeling effect.

By using the exfoliating agent, there is a state of phase separation between a non-absorbing surface such as a white board and the coating film, so that it is possible to improve the erosion property.

The releasing agent is preferably used in an amount of about 5 to 30% by weight, and more preferably about 10 to 25% by weight.

If the release agent is used in an amount of more than 30% by weight, there is a problem of blurring upon erasing, difficulty in obtaining a smooth and uniform handwriting, and deterioration of water solubility. When the amount is less than 5% by weight, do.

It is possible to use pigments and dyes widely used as colorants in general.

The colorant may be, for example, an inorganic pigment, an organic pigment, a white pigment, a pearl pigment, a metal pigment, a fluorescent pigment, etc., alone or in combination.

The organic pigments include azo pigments, phthalocyanine pigments, quinacridone pigments and the like. Examples of the white pigments include titanium oxide, zinc oxide, and zinc, and the fluorescent pigments include Are fluorescent materials for daylight fluorescent and phosphorescent pigments.

About 1 to 50% by weight of the coloring agent is used.

The present invention may further comprise a viscosity adjusting agent, an antifungal agent, and an antibacterial agent.

According to the water-soluble smelting solid shape marker having water-soluble properties according to the present invention, it is possible to easily apply writing or drawing on a non-absorbing surface such as a whiteboard, glass, plastic, It is useful.

In addition, unlike conventional chalk or the like, dust-free solid maca having water-soluble properties according to the present invention does not scatter dust during coating or erasing, so that it can be smoothly applied without harming the human body.

In addition, according to the present invention, it is possible to cleanly erase without any marks by a cloth or a small hole after coating, and to clear it after a long period of time. In addition, And thus the scavenging ability is very excellent.

Further, according to the water-soluble, solid-form solid maca according to the present invention, since water-soluble, which can be erased by wiping with water after application, is more easily and easily erased.
