A coating composition for wallpaper coating {A painting composition for coating wall-paper}

The present invention relates to a coating composition for a wallpaper coating containing a natural raw material as a main component, the composition of the main component is one or more far-infrared radiation components selected from ocher, charcoal, jade, ganban stone, mica, ceramic, shell, and the binder component As a additive, a composite binder composed of a natural binder composed of natural inorganic matter, a natural polymer substance and a protein, or a mixture of a synthetic binder composed of acrylate, styrene, butadiene, vinyl acetate, etc., and an appropriate ratio of thickener, lubricant, antifoaming agent, etc. as additives By mixing evenly to form an aqueous coating composition, when the coating composition is coated or woven by woven fabric, nonwoven fabric, paper, etc., and used as a super medium or wallpaper, the far infrared rays and anions emitted from the inorganic components are released and natural products The binder consists of ordinary wallpaper Organic solvents released from complexing, interior materials, and new house syndrome caused by formalin or cement toxicity are improved, and the treatment between cement and human body with far-infrared and natural substances beneficial to the human body prevents harmful substances and improves health. The present invention relates to a paint composition for wallpaper coating, which has been developed to improve our residential environment into a natural environment suitable for the well-being era.

One of the most important elements in our daily life is the residential environment centered on the housing. The residential environment is diversified not only in residential homes but also in offices, sales places, and various accommodations.

Various interior materials are inevitably applied to the construction of such residential facilities, and wood interior materials such as cement-based walls and plywood made of various woods, wallpaper, textile materials, paints, etc. are applied. Some raw materials are used as raw materials for the materials, but by using a substantial portion as a synthetic material to improve durability, it is found that various harmful substances are released to adversely affect the human body.

In particular, interior materials that are applied to residential spaces where people live and rest for a long time have a close impact on the environment. So far, cement walls or plywood where formalin is detected, grasses containing formalin, and organic solvents Since the interior environment is mostly used to decorate and finish the indoor environment using exposed plaster, such interior materials inevitably release harmful substances and dominate most residential environments such as living rooms or homes.

These indoor harmful environments include respiratory diseases (cold, asthma, etc.) and skin diseases (atopic dermatitis, rashes, etc.) caused by organic solvents or formalin, and are most severe in newly decorated homes and offices. An incompetent guest, "SICK HOUSE SYNDROME," coined the phrase.

In order to improve the problems of the residential and indoor environment, in recent years, some specific companies have been developing improved products which have reduced the emission of harmful substances in interior materials. In 1997-15927 (Patent No. 245290), 5 to 15% by weight of water, 15 to 20% by weight of binder, 10 to 20% by weight of ocher or illite, 10 to 20% by weight of gannetite, 4% by weight of starch, and 0.1 to about 0.1% of antifoaming agent. The spinning material obtained by mixing evenly at a composition ratio of 0.5% by weight, 0.05 to 0.1% by weight of dispersant, and 30 to 45% by weight of calcium bicarbonate is applied to the surface of the backing paper by adjusting the layer thickness with an air knife and dried, and then applied spinning Top coating of the material selected from among UV, urethane, moisture-permeable urethane in order to protect the surface of the radioactive material layer in order to protect the wallpaper containing the radioactive material Methods have been proposed.

The developed product has the advantage that the user's health is enhanced by releasing constituent substances beneficial to the human body such as far infrared rays, minerals, germanium, etc. from the radiation to the living environment, and does not cause pollution by the biodegradation action of starch at the time of disposal. However, although the effect can be acknowledged to some extent, there is a problem that it is very difficult to be widely used as a product that cannot be used by the general public as a high viscosity wallpaper manufacturing method that is practically difficult to commercialize.

In addition, Korean Laid-Open Patent Publication No. 10-2004-0065540 is a natural ocher wallpaper used for finishing walls, ceilings, and floors as one of the interior materials for construction. By applying various colors, it gives a plastering effect. By using only natural wheat grass using seaweed for the silk and paper contact, it attempts to differentiate it from the general wallpaper using chemicals as its main ingredient, and maintains the smell of natural humidity and ocher. Attempts have been made to solve problems such as formaldehyde in sick house syndrome by using the deodorant effect of loess.

In addition, Korean Patent Laid-Open Publication No. 2004-0064656 discloses a new material for solving sick house syndrome due to chemicals, zinc oxide 30-40%, manganese dioxide 10-20%, acidic clay 20-30%, magnetite 20-30. A method of protecting the human body from sick house syndrome has been proposed by presenting a mixture composed of% to effectively adsorb and decompose formaldehyde, toluene and various volatile organic compounds (VOC).

In addition, as a slightly different technology, Korean Laid-Open Patent Publication No. 1999-0028236 includes a photocatalyst layer, a carrier, and an adhesive layer existing between the photocatalyst layer and the carrier as a photocatalyst manufacturing technique, and the adhesive layer contains a silicone-modified resin and polysiloxane. It is made of resin or colloidal silica-containing resin, the photocatalyst layer is made of a composite consisting of a metal oxide or hydroxide gel and a photocatalyst, and as a photocatalyst coating material for forming the structure, a silicon compound, at least one metal oxide or metal hydroxide sol, And a technique for expressing the effects of antibacterial, deodorant, antifouling, etc. by coating on the wallpaper using a photocatalyst support structure consisting of one or more photocatalyst powder or sol.

However, these conventional technologies can be expected to have some weak effects, but the effects are not practical because they are insignificant, or the technology that can describe the effect is not a product that is difficult to be easily applied by the general consumer or the interior business, it is not successful in commercialization There is a situation.

In order to overcome the problems of the prior art, a more advanced composition is required, and in particular, it is possible to block or remove or minimize the harmful elements of the human body, express a beneficial effect on the human body, and very easy to apply the field so that it is natural and healthy. It is necessary to develop products that are beneficial and practical.

The inventors of the present invention to solve the conventional problems, to improve the living environment, such as damage from harmful chemicals generated from wallpaper and various interior materials, anyone can use in a variety of materials and do not contain formarin or organic solvents It provides a coating composition that prevents cold radiation and emits far infrared rays and negative ions, and can be coated on a cement wall or coated on a wallpaper to block or suppress human harmful substances generated from cement, plywood, wallpaper, adhesive, etc. to create a pleasant environment. New compositions were invented.

In order to solve such a conventional problem and improve the living environment, efforts to block the cause should be prioritized. In particular, the present inventors have developed a mortar using loess, mineral or rock powder, and applied for a patent, and are currently commercializing loess paint. Developed and marketed it, but after feeling the need for some improvement, researched the far-infrared radiation product for coating suitable for multi-purpose use. If the composition of the coating composition is selected by harmonizing the types of binders to be adhered to paper or fibers, it may be possible to block or maximally block formarin or various organic solvents, which are the culprit of sick house syndrome, so that they may not adversely affect the human body. It was found that the present invention was completed.

Therefore, an object of the present invention is composed of a mixed binder containing a far-infrared radiation component of a natural material and a natural binder and a synthetic binder, which is also a main component of a natural material, which can achieve a far-infrared radiation effect and a harmful chemical blocking effect at the same time. To provide a composition.

Particularly, in the present invention, more specifically, one or more far-infrared radiation powders selected from ocher, charcoal, jade, elvan, mica, ceramics, and shells, and a binder component are natural binders or acrylics composed of natural inorganic materials, natural polymer materials and proteins. It is an object of the present invention to use a composite binder composed of a mixture of synthetic binders composed of latex, styrene, butadiene, vinyl acetate, and the like, and to provide a new composition of wallpaper coating containing conventional additives.

In addition, another object of the present invention is more convenient in the composition of such a natural material composition, coating, spraying, mixing, laminating, printing on the interior materials of various structures in the same manner as conventional paints in addition to coating such as wallpaper or super medium It is to provide a composition that can be applied in a variety of ways, including.

The present invention is a coating composition composed of a natural inorganic material, a binder, and a conventional additive,

A) 20 to 50% by weight of at least one far-infrared radiation powder selected from ocher, charcoal, jade, elvan, mica, ceramic and shell;

B) vinyl acetate or acrylate synthetic binder as a binder component; Or 0.5-40 wt% of natural rubber (LATEX), 0.5-40 wt% of rosin, 0.5-40 wt% of alginic acid, 0.5-40 wt% of chitosan, 0.5-40 wt% of casein, 0.5-40 wt% of starch, Natural binder containing 0.5 to 40% by weight of gelatin, 0.5 to 40% by weight of glue, 0.5 to 40% by weight of flour, and 0.5 to 40% by weight of colloidal silica; Or 10 to 50% by weight of the composite binder consisting of a mixture of the synthetic binder and the natural binder,

C) 10-50% by weight of water, and

D) 0.5 to 8% by weight of an additive component containing at least one of a dispersant, an antibacterial agent, a thickener, a lubricant and an antifoaming agent as a common additive.

It is characterized by the composition containing a.

When explaining the present invention in more detail as follows.

The basic composition of each component used in the present invention is composed of a far-infrared radiation component of a natural material, a synthetic binder or a natural binder or a composite binder combined with a natural binder, water, and additives.

The far-infrared radiation component of the natural material used in the present invention is a powder obtained by pulverizing one or more far-infrared radiation components selected from ocher, charcoal, jade, elvan, mica, ceramic and shell to a size of 250 mesh or more, preferably 250 to 500 mesh. It is good to use when considering the physical properties and applicability after mixing, the amount should be 20 to 50% by weight. If the amount is small, the fluidity or flowability is good, but the far-infrared radiation effect is insignificant. If the amount is too much, the binder and water content is relatively small, so that high viscosity causes dust, cracking, poor fluidity, and no flow. Is impossible.

Ocher used as a natural material in the present invention is a composite inorganic material made of porous, absorbs and radiates far infrared rays, radiates to the human body to activate metabolism and blood circulation to prevent aging of the body, recovery from chronic fatigue, etc. Is known to be large. In Oriental textbooks, such as the herbaceous tree, Dongbobogam, antimicrobial herbicide, distilled herb, and herbaceous gland, the ocher's weakness is a large and detoxifying poison. Such ocher has great power to break down the odor and disintegrate it in a short time, even if it covers more than 1cm thickness even if the substance with the severe odor by the action of porous multilayer structure and microorganisms and enzymes. It is a very good substance that prevents cold radiation harmful to human body while emitting large amount of excellent infrared rays.

Charcoal is a black mass from which wood is burned. It is a carbon mass before ashing. It is the most porous material on earth with an inner surface area of 300 square meters per gram of char. It is far infrared radiation, anion generation, medically adsorbent, antidote. , Analgesic, antipyretic, anticancer, etc. are said to be effective, and our ancestors' use of charcoal was excellent.

Jade is composed of about 45 kinds of minerals. Among them, it is a natural far-infrared emitter containing calcium and magnesium, which are extremely necessary for the human body. It is said that jade has mysterious efficacy and good health. It is a pronoun of 氣).

Elvan is a porous rock that is widely distributed in Korea, and has been used as a weak stone in China for more than 2,000 years. It has excellent adsorption power due to its porous structure.

Other components, such as mica, ceramics or shells, are known to have far-infrared radiation, and due to their unique characteristics, these components affect the human body according to the application method considering their characteristics. Contributes greatly to the beneficial impact

Among them, the ceramics used in the present invention include, for example, 5-30% by weight of macrocrystals, 5-30% by weight of aphrodite, 5-30% by weight of rare earths, 5-30% by weight of silica, 5-30% by weight of gannetite, and titanium 1-30. A mixture of a weight%, zirconium 1 to 30% by weight, and the like may be pulverized to 200 mesh or more, evenly mixed, calcined to 1300 ° C. or more, and pulverized to 300 mesh or more.

The various inorganic materials used in the present invention are used in appropriate amounts in the above ratios for the beneficial effects on the human body such as the various beneficial properties described above and far-infrared radiation. In case of using small amount of inorganic materials such as ocher, charcoal, elvan, mica, shell among the far-infrared radiation components, the fluidity is good, but the functional effect pursued is weak. there is a problem.

On the other hand, the binder component used in the present invention may be a composite binder or a composite binder composed of a natural binder or a mixture of natural binders blended with the binder, and the binder used in the present invention may be a natural binder and a synthetic binder. It is most typical that the mixing ratio is 10 to 40% by weight of the natural binder: 90 to 60% by weight of the synthetic binder, such as 10% by weight, 90% by weight, 20% by weight and 80% by weight. It can be formulated by blending and adjusting the product so as to be wt%, 30 wt% and 70 wt%, 40 wt% and 60 wt%. Maximizing the content of the natural ingredients in the order illustrated in the above mixing ratio is a pure natural coating composition, and in the reverse order to maximize the general coating composition made of synthetic resin.

The synthetic binder according to the present invention is preferably a vinyl acetate-based or acrylate-based binder, for example, vinyl acetate-based binder 40-80% by weight of vinyl acetate (VAM), butyl acrylate monomer (BAM) 5-30% by weight, 1-30% by weight of ethyl acrylate monomer (EAM), 0.05-10% by weight of ethylenethioglycol, 0.5-10% by weight of glycidyl methacrylate, 2-5% by weight of anionic surfactant and ratio What consists of 2-5 weight% of ionic surfactants can be used, For example, 40-80 weight% of methyl methacrylate monomers, 5-30 weight% of butyl acrylate monomers (BAM), Ethyl acryl-type binder 1 to 30% by weight of acrylate monomer (EAM), 0.05 to 10% by weight of acrylonitrile, 0.5 to 10% by weight of n-butylmethacrylate monomer, 2 to 5% by weight of anionic surfactant and 2 to 5% of nonionic surfactant In% Lure Jean binder can be used.

Such vinyl acetate-based binders or acrylate-based binders may be said to have the best copolymerization of binders having different compositions in terms of workability and blending properties.

The raw material compounds in the synthetic binder used in the present invention are dependent on the adhesive strength, hardness, etc., depending on the ratio of the amount used, the solid content of the product is high and low depending on the size of the compound content, the functional monomers of the product according to the type and amount used There is a huge difference in characteristics. For example, functional crosslinking agents, such as ethylenethioglycol and glycidyl methacrylate, can control the degree of polymerization, impart friction resistance or cold resistance, and cannot be expected when used in small amounts. The factors, of course, tend to hamper the overall physical properties.

Acrylic binders require a dispersant or surfactant that can bring about changes in physical properties when dispersing porous inorganic materials such as ocher and charcoal.Aqueous butadiene rubbers and aqueous polyurethanes are flexible. Although adhesion and flexibility are good due to the formation of the film, there is a problem that physical properties such as workability are poor as an adhesive agent of an inorganic material.

According to the present invention, a method for producing the synthetic binder is, for example, by mixing each component of the binder composition to 40 to 50% by weight and water to 50 to 70% for 5 to 6 hours at 70 to 85 ℃ in the presence of a catalyst After the dropping reaction, the unreacted material was removed under vacuum, cooled, and transferred, thereby preparing a synthetic binder in the form of an aqueous emulsion resin solution.

In addition, the natural binder used in the present invention is, for example, 0.5 to 40% by weight of natural rubber latex, 0.5 to 40% by weight ROSIN, 0.5 to 40% by weight alginic acid, 0.5 to 40% by weight chitosan, 0.5 to 40% by weight casein %, 0.5-40 wt% starch, 0.5-40 wt% gelatin, 0.5-40 wt% glue, 0.5-40 wt% flour, borax and 0.5-40 wt% colloidal silica can be used. Here, the natural rubber latex can be used to lower the hydrogen ion concentration (pH), rosin (grosene) was used after saponification by soaking with alkali, casein was used after stabilizing as borax. Chitosan is preferably used after being solubilized with acetic acid or citric acid. In addition, colloidal silica was used by minimizing the sodium remaining in the manufacturing process using an ion exchange resin.

In order to manufacture such a natural binder, for example, 20 to 60% by weight of the polymer material constituting the natural binder and 40 to 80% by weight of water are added dropwise in small amounts by a suitable addition procedure at 60 to 95 ° C in the presence of a crosslinking agent. After the reaction was prepared by adding and stirring the characteristic material to complete the preparation.

In the present invention, it is preferable that both the synthetic binder and the natural binder to prepare a binder using water in the manufacturing process, wherein the binder component and the final content of the water should be 10 to 50% by weight based on the total composition, respectively. Good physical properties and applicability In addition, it is most typical that the sum of the content of water and the binder component in the total composition is 25 to 80% by weight. If the total content of water and the binder is less than the above range, the role of the binder is insufficient. After drying, it is poor in dust generation and friction fastness, and the product is poor in case of excessive use, when the coating state of the surface coated with the paint is not appropriate, the problem that the original functionality intended for the present invention is not sufficiently exhibited. There is.

As such, when a small amount of binder material is used, the adhesion of the composition decreases, dust generation and cracking occur severely, and when used excessively, cohesion and adhesion increase, but the amount of far-infrared radiation component is relatively small, and thus the effect of far-infrared radiation pursued in the present invention Falls.

In addition, a conventional additive component may be used as a component used as an additive in the present invention. For example, one or more of a dispersant, an antimicrobial agent, a thickener, a lubricant, and an antifoaming agent may be used in an amount of 0.5 to 8 wt% based on the total composition. . In this case, each additive component used may be a component usually used in functional paints, but is preferably an antimicrobial agent composed of 0.1 to 5% by weight of a conventional dispersant, silver nano silver, copper or a conventional component, for example, based on the total composition. -1 weight%, a conventional thickener or 0.1-5 weight% of a lubricating agent, and 0.1-1.0 weight% of a normal antifoamer can be used.

The choice and application of additives, dispersants, antibacterial agents, thickeners, lubricants and antifoaming agents in the present invention can also be said to affect the physical properties of the composition of the present invention.

Dispersants play a role in forming a uniform solution of inorganics, water, and binders, and play an important role in controlling lubricity and flowability. Of course, there is nothing important, but it is also important to use what kind of composition. Although there are several kinds of dispersants, it is one of the preferred ones to use acrylic acid copolymer sodium salt in the present invention. Excessive use of such a dispersant speeds up the dispersion of inorganic materials such as ocher, elvan, ceramic powder, etc., and when the composition is applied to woven or nonwoven fabrics, it is too penetrated, causing deterioration of product quality. There is a problem in that it is difficult to produce a uniform composition due to poor dispersibility.

Antimicrobials and deodorants can also be used, for example, nano-silver, copper compounds sulfur boric acid, or specially formulated organic compounds such as charcoal or titanium nano-barium. It plays an important role in purifying the odor caused by. If such an antibacterial agent or deodorant is used in small amounts, its effect cannot be expected, and in the case of excessive use, a change in physical properties as well as unnecessary costs are increased, so that an appropriate amount is not necessary. Elvan has some antibacterial activity, but it is insignificant that it can not be felt in real life. However, since elvan is a porous rock, the adsorption power can be said to be very good, so it is better to apply it as a water purification agent, and when used in a small amount, its effect is insignificant, and when used in excess, the flexibility becomes worse due to hardness increase.

Examples of the thickener include alginic acid, chitosan, herbal, and casein, which are natural polymers, or PVA (polyvinyl alcohol), PVP (polyvinylpyrrolidone), CMC (carboxymethyl cellulose), and HPC (hydroxypropyl cellulose). ), MC (methylcellulose), HEC (hydroxyethyl cellulose) and the like, it is necessary to maintain uniform viscosity, lubricity and flowability appropriately. When too small amount of thickener is used, the effect is insignificant, which can not guarantee the uniformity of the product, prevent the precipitation of minerals, and when it is coated on cloth or non-woven fabric, it will flow down to the opposite side of the coating surface due to low viscosity. I can't. On the contrary, in the case of too much use, the adhesion is impaired due to impede penetration during coating.

In addition, an antifoamer and other additives may use a conventional component.

These additive components are added by uniformly dispersing and stirring when blended with the far-infrared radiation component, the binder mixed with water and the like, and when the flowability and viscosity of the composition are appropriate, the addition of each component is stopped to meet the product characteristics or the management value. It is good to manufacture in a reasonable state. Preferably, the viscosity of the entire composition is 500 to 50,000 cps, more preferably 1,000 to 25,000 cps, which is good when considering the properties and applicability.

The composition of the present invention prepared as described above may be used as a paint or coated with a woven or nonwoven fabric, paper, or the like. The coating may be used as a super medium or coated as a wallpaper by knife coating, immersion processing, or spraying. , The wallpaper, etc. to which the composition of the present invention is applied has a well-being environment in our living environment due to the far-infrared ray and anion emitted from the far-infrared radiation component powder, and improves the living environment in the high sea age, especially preventing cold radiation, By improving the sick house syndrome caused by organic solvents and formalin or cement toxicity, filling the cement and human body with far-infrared and natural substances beneficial to the human body, rather than a harmful environment, can greatly help health promotion.

As described above, the composition of the present invention is a composition in which a far-infrared radiation component such as ocher and a binder are mixed, and when these two components are mixed in the same ratio, it may be difficult to apply due to excessive increase due to the change of surface activity during stirring. Jade mica and the like have little voids and have no shrinkage, so there is no difficulty in coating. In addition, the addition of starch and calcium bicarbonate used in Korean Patent No. 245290 recognizes the biodegradability of the starch, but when added in excess of about 30 to 45% by weight in the case of calcium bicarbonate, the flowability as a functional plaster coating agent such as paint or knife coating agent It can be said that the workability is very bad or the property difficult to continuous work. Therefore, the criteria for selection and composition according to the above-mentioned ingredients are to be selected and used appropriately in consideration of various uses or coating properties within the scope of the present invention. In addition, the composition according to the present invention can be used by coating the wallpaper, super medium, various storey textile materials, wood, synthetic resin, cement, mortar, gypsum board, various functional coating surface, and the wall surface, floor, ceiling, removable or prefabricated. It can also be applied to sheets, panels, pallets, furniture, interior equipment, and the like. In particular, when using a slight adjustment of the composition or the composition ratio of the composition for the composition of the present invention may be used as an anti-slip coating, such as carpet that should be applied slightly thicker than other interior materials.

As described above, the composition for wallpaper coating according to the present invention is a very beneficial composition having the effect of preventing, suppressing, neutralizing, and blocking the emission of harmful components and at the same time showing a far-infrared radiation effect. Even without the top coating, it will not be buried or damaged when contacted. In addition, in order to require a smooth surface or to perform special plastering, the surface of the composition of the present invention may be subjected to conventional surface treatment with other suitable components.

Hereinafter, the present invention will be described in detail with reference to Examples, but the present invention is not limited by Examples.

In this case, the standard raw material is adopted as loess. If the properties of the pores with a lot of porcelain or charcoal is adjusted, the most difficult material, ocher, was selected as the base material, because ganbanite, mica, ceramic, and shell meal can be mixed and applied to obtain good results.

Examples 1-4, Comparative Examples 1-2

The composition was prepared by combining the ingredients of Table 1 below.

Loess, water-containing binder, thickener, antifoaming agent, antimicrobial agent, and dispersant were mixed and checked every 5 minutes with stirring at 1,000-2,500 rpm for 30 minutes to 1 hour.

The ocher was used by pulverizing more than 300 mesh, and the binder, which plays an important role in physical properties, contains at least 20% by weight relative to the total weight to synthesize acrylic, vinyl acetate, butadiene, polyurethane, etc. into a water-soluble emulsion. As a result of repeated experiments, the copolymer binder of vinyl acetate and acrylate is the most durable in terms of workability and blendability, and these two kinds of binders are used as a natural binder. By using natural rubber, vegetable resin, gum, wheat flour, starch, rosin, chitosan, seaweed, etc., which are plant extracts, they are able to overcome the shortcomings of satisfying physical properties with only a few ingredients and increase compatibility with each other. Could be prepared as.

In addition, the additives are appropriately used in each content, but the content of the binder component containing ocher and water is controlled, while the additives used (thickeners, antifoams, antibacterial agents, and dispersants) maintain a specific ratio and exhibit far-infrared radiation function. A coating composition for coating was prepared.

Inorganic materials used in the examples are based on ocher powder, and jade, ganban rock, ceramics, and mica powder are not porous, such as soil or charcoal, or rock powder, including elvan, which is slightly porous. Because the contact surface of is small, the amount of water or binder is at least slightly viscous, but the surface area of charcoal and soil, including loess, has a difficult property of changing its properties depending on the place of origin and the place of extraction. (Al ₂ O ₃ ) 27.06 wt%, silicon oxide (SiO ₂ ) 57.52 wt%, potassium oxide (K ₂ O) 3.395 wt%, titanium oxide (TiO ₂ ) 1.47 wt%, ferric oxide (Fe ₂ O ₃ ) 4.35 Large quantities of yellow soil in Korea, consisting of weight%, copper oxide (CuO) 2.70 weight%, and zinc oxide (ZnO) 1.51 weight%, were selected as the reference raw materials.

As a binder component containing water, a natural binder prepared by a modification reaction of a natural polymer material and an animal protein, and a synthetic binder in which vinyl acetate and acrylate are mixed are used alone or in combination, respectively. The thickeners used as additives were casein, fibish, HI, antifoaming agent, silicone based, antibacterial, antiseptic silver or methylparaben, propyleneparaben, dispersant Acryric copolymer sodium Salts were used respectively.

Table 5

Experimental Example

Experimental results for the composition were shown in Table 6 below.

Comparative Example 1: stirring and dispersion were impossible due to the absorption and hygroscopicity peculiar to ocher.

Comparative Example 2: Mixed water or binder was also impossible to stir and disperse.

Example 1 The viscosity of the mixed water or binder was about 50,000 cps with relatively low fluidity, and the viscosity increased in proportion to the stirring time.

Example 2 The viscosity and appearance are good and are good even in stirring.

Example 3: Fluidity and viscosity maintained around 10,000 cps.

Example 4 fluidity, appearance, flowability is good but the viscosity is formed to 5,000cps

          Far infrared ray emitting material is rather small but can be used as a product.

As shown in the above experiments, the blended loess component was most preferable in the vicinity of 40% by weight, and it was confirmed that it is most suitable to prepare the physical property as a binder, thickener, and dispersant.

Antibacterial and antifoam did not change the physical properties directly, but in the case of antifoam, the appearance was changed by bubbles after work.

In this way, as a result of the cross-test of each component in Examples 1 to 28 and Comparative Examples 1 to 2, the fluidity, flowability, precipitation prevention, adhesion, frictional fastness, water resistance, and the like of the products are very poor or poor. , The following symbols are used in the order in which they are judged to be suitable or good.

Viscosity measurement, which influences the quality of products, is available from TOKYO KEIKI CO. As VISCOMETER of LTD, it measured by "Model-BM" instrument and measured temperature was 25 ℃. For paint property tests such as flowability and adhesion, see KS M 5980, KS M 6711, and KS M 8303. Sedimentation prevention and workability were judged as sensory after standing in a transparent container.

In the field sensory experiments, cement blocks of 38cm in width and 18cm in length were stacked, and then plastered and divided into three surfaces except for the entrance, respectively, by spray, brush, and roller. The criteria are as follows.

1. ××: As viscosity is not formed, it is hardly used for products such as paint and coating products.

          Not available. Viscosity more than 300,000cps.
