Description

A composite of bio-function plaster for anti-sticking using ceramic raw materials}

The present invention relates to the manufacture of a coating material used in the indoor and outdoor walls and pillars of a building having an eco-friendly bio performance by preventing graffiti, indoor bio-functions, such as stickers in the outdoors, and prevention of graffiti in the interior, Specifically, it is applied to the surface of the adherend to form a composite impermeable membrane, thereby lowering the adhesive strength of the adhesive applied to the back of illegal walls, advertising paper, etc. to prevent the adhesion of promotional materials, flyers, stickers, etc. Eco-friendly bio-coating with excellent anion and far-infrared radiation, excellent antibacterial and anti-fungal performance, by preventing the graffiti caused by ball pen, pencil, etc. It relates to a composition of ash.

Promotional materials such as stickers, posters, etc. are printed on advertisements and are used to be attached to poles or facilities. If the commercials used in this way are awkward, they hurt the aesthetics. In spite of this, publicity materials such as stickers are illegally attached to the city, and thus, many efforts are made to remove such promotional materials, causing unnecessary waste of time and personnel. Once the promotional material is attached, it is difficult to remove it by a strong adhesive force, so various methods are used to prevent sticking. Conventionally, Korean Utility Model No. 0323760 (designated name: mural and photo-print sticker attachment prevention sheet) among the methods for preventing the sticking of the sticker used is a back layer made of a vertical corrugated polyurethane foam sheet and a PVC sheet layer. It consists of a print layer printed with murals or photographs, and a surface layer coated with a transparent paint to prevent sticking of stickers. Attaching the anti-sticker sheet formed of a corrugated protrusion configured as described above was to lower the sticking function of the sticker and facilitate the removal of the sticker. Such a sticking preventing sheet is difficult to manufacture because it consists of a surface layer coated with a transparent coating on the corrugated projection, there is a problem that the corrugated projection is damaged. In addition, since the adhesive layer is not formed, adhesives are applied to the surface of poles or facilities using spray or brush, or adhesives are attached to the sheet, resulting in stains or wrinkles, and thus uniform construction quality cannot be obtained. As the non-uniformly applied, there is a problem that the sheet is dropped from the surface of the pole or facility.

The design of the past domestic patent or utility model is designed to be used only outdoors, and its use in the room has not been examined, and thus its function was not exhibited except for a partial role. In addition, indoors can be said to be necessary items to prevent graffiti by a pencil or a ballpoint pen rather than a deterioration function of promotional materials. In fact, in the case of school classrooms, each school is different due to the graffiti of students, but it is a waste of a lot of money by painting a new wall several times each year.

In recent years, in order to improve the living environment of human beings exposed to various harmful substances, Korea has enacted indoor air purification methods and demanded more eco-friendly living. This is an indispensable measure for health as an effort to improve the current living environment that is easily exposed by various chemicals used in buildings. The destruction of living environment in living spaces, such as buildings, is caused by various chemicals used in various processes of the building. The main culprit behind the destruction of living environment is mainly adhesives of wallpaper and formaldehyde and volatile organic compounds contained in wood. have.

The present invention has been made to solve the above problems, to impart a water-repellent, oil-repellent function on the surface of the adherend to reduce the adhesion of promotional materials, such as posters, stickers, eco-friendly bio coating material composition using a natural ceramic material To clean indoor air environment by effect of negative ion generation, far infrared ray emission, deodorization, etc., to show antibacterial antifungal performance, increase far-infrared ray and negative ion radiation, and provide a beneficial living environment for human body It is to provide eco-friendly bio coating material.

The biofouling material for preventing adhesion according to the present invention uses a silicone sealant to impart water repellent and oil repellent properties to the surface, and reacts with an appropriate amount of volatile solvent to dissolve it to form a composite silicone solution. When exposed, the volatile solvent component is removed by volatilization into the atmosphere and the silicone component remains after infiltration from the surface layer of the construction site to form a film. At this time, it is preferable to synthesize an acrylic resin or an ethylene vinyl acetate resin in the solution in order to increase the adhesion when the solution is penetrated from the surface layer. The solution is excellent in tackiness but mixed with a large amount of cement in order to compensate for weakness such as strength expression and to give homogeneity with the material of the surface to be installed. In this case, cement may be cemented carbide, general Portland cement, back cement, etc., and in part, calcium carbonate, fly ash, or the like may also be used.

Calcium stearate is used to harden the cement mixture by mixing the cement and kneading the gel into a gel state or to prevent delamination and to enhance water repellency. At this time, stearic acid salts such as zinc stearate may be used instead of calcium stearate.

Following the above process, cliptonite, which is a kind of phosphate mineral and zeolite mineral, is used to impart environmentally friendly functions. The usage criteria of phosphate minerals should be about 700 to 1,200 anions generated per cubic centimeter, far infrared emissivity of 0.90 or more, deodorization rate of 70% or more.

The composition of the present invention is obtained by adding 70-80% by weight of toluene to 20-30% by weight of the silicone sealant and dissolving it to obtain a primary solvent, the content of the primary solution to 85-95% by weight of acrylic resin 5 ~ Mixing 15% by weight to obtain a synthetic solvent, to about 40-44% by weight of the synthetic solvent 52 to 56% by weight of cement and calcium stearate 2-6% by mixing about 12 to 72 hours in a sealed container at room temperature After the maturing time to prepare a mixture kneaded in a gel (gel) state. At this time, the phosphate mineral is added 3 to 7% by weight based on the amount of cement, the cliptonite is added to 10 to 20% by weight based on the amount of cement.

Since the composition of this invention contains a large amount of volatile materials, the component becomes oily, and since this oil liquid and cement were mixed, cement stops hydration and a condensation hardening reaction does not advance.

However, when the construction is completed using the composition of the present invention, the volatile material used as the medium is volatilized to the atmosphere, and the cement starts to harden by the condensation curing reaction. At this time, some of the silicone components in the composition of the present invention penetrates into the pores in the concrete to form a film, and the composite of the silicone components, cement particles, and calcium stearate remaining on the surface exhibits water and oil repellent properties.

In addition, the phosphate mineral added to the coating material composition according to the present invention is a powder form, in order to be evenly dispersed in the solution, using a 350 mesh 90% or more, the average particle diameter of the cliptonite is 2.1 ㎛.

Hereinafter, the present invention has been described in detail through examples. However, it is obvious that the limitations of the present invention are not limited by the following examples, and may be modified by those skilled in the art to which the technology of the present invention belongs without departing from the scope of the claims.
