As described above, the composition obtained by squeezing the compact obtained by pressing the composition in the mixing process without using water for 24 to 30 hours at room temperature is coated or coated on the fabric fabric. As a result, the skeleton of the fabric fabric is kept intact, and volatile organic compounds, odor components, and other harmful substances in the air can be easily adsorbed and removed. The composition further includes zeolite particles which are a raw material for deodorization. The zeolite is preferably fine particles. In particular, it is preferable to apply active mordenite having an average particle diameter of 1000 mesh. Synthetic zeolites can release formaldehyde, a substance that is harmful to the human body, but naturally active mordenite particles rarely release formaldehyde. The active mordenite content comprises 15 parts by weight relative to the total weight of the composition.

Sodium silicate and calcium silicate in the composition of the present invention serve as an organic binder to prevent cracking and cracking of the fabric as an adhesive component.

In another embodiment, the eco-friendly high-performance fiber wallpaper composition according to the present invention is prepared through the following steps.

First, when the total weight of the composition is 100 parts by weight, 15 parts by weight of zeolite particles are mixed and stirred at a temperature of 30-35 ° C. in a mixture of 30 parts by weight of phytoncide powder and 15 parts by weight of liquid pine needle extract. The zeolite particles preferably have an average particle diameter of 1000 mesh, and are preferably used in the form of an aqueous dispersion for ease of processing.

Next, the water product is finely pulverized and left for 50-60 minutes at a high speed of 3000-3500 rpm by a nano grinder to separate the slurry and the supernatant. The slurry and the supernatant are then filtered to recover the aqueous product.

The recovered aqueous product is aged for at least 24 hours with mixing and stirring. While maintaining the temperature of the mixture at 31-35 ° C, preferably 31-32 ° C, 3 parts by weight of sodium silicate and potassium silicate, which are adhesive additives, were mixed and stirred for a short time.

The amount of such components to be used may be 1 to 2 parts by weight of dispersant, 1 to 3 parts by weight of foaming agent, and 1 to 3 parts by weight of antifoaming agent based on the total weight of the composition.

The dispersant serves to control lubricity and flowability, and it is preferable to use an acrylic acid copolymer. If the dispersant is used excessively, the dispersing speed is increased, and when it is applied to the woven fabric or fabric fabric, the penetration is too high, which leads to deterioration of product quality. If the dispersant is used too little, it is difficult to produce a uniform composition due to the poor dispersibility. Lose.

The blowing agent may be used by selecting one or more from the group consisting of azo compounds, nitroso compounds and sulfonylhydrazide compounds.

If too little foaming agent is used, the hardness and specific gravity are very high, and if too much foaming agent is used, foaming of a stable cell structure cannot be obtained due to excessive foaming, and thus mechanical properties of the product are sharply lowered.

Antifoaming agent serves to remove bubbles generated in the fiber wallpaper composition, and nonionic surfactants, other nonionic surfactants based on octyl alcohol, cyclohexanol, other higher alcohols, ethylene glycol, sorbitan fatty acid esters, etc. Can be used.

The fiber wallpaper composition according to the present invention is applied to the fiber wallpaper through the following steps.

First, as described above, a fiber wallpaper composition comprising phytoncide powder, liquid pine needle extract, zeolite, tourmaline, antibacterial agent, starch and the like is prepared. As a method of applying the composition to the fiber wallpaper fabric, a conventional welding method commonly used in the art, for example, gravure coating, comma coating, roll coating, bar coating and the like can be used. It can be selectively used according to the material, requirements or area of the fiber wallpaper to be coated, the thickness can be adjusted.

After coating the composition on the fiber wallpaper fabric and dried. The drying temperature is not particularly limited, but in view of productivity, etc., the drying temperature is usually performed at a temperature of 170-190 ° C using a heat treatment chamber. Next, the desired wallpaper is embossed or printed on the fiber wallpaper fabric, and then the finished wallpaper is wound up. Printing may be done before the drying step.

In another embodiment, the individual ingredients are mixed and aged for a short time with uniform stirring. The compact obtained by grinding the mixture finely and compacted is aged at about 60 ° C. for at least 24 hours. Next, the mixture is filtered to remove the precipitate to provide a fiber wallpaper composition.

In another embodiment, the aging temperature is 31-32 ° C. The mixture is aged for at least about 24 hours with stirring. Subsequently, additives are mixed and stirred in the mixture. The mixture is stirred for a short time while maintaining the temperature of the mixture at about 31 ° C. to provide the final composition.

In another embodiment, the composition is applied to the fibrous wallpaper fabric in a coating or batch manner and wound up after heat treatment to provide the final wallpaper product. The fiber wallpaper composition obtained as described above is aged at least about 24 hours while maintaining at a temperature of about 31-32 ° C. to obtain a fiber wallpaper composition. The obtained composition is applied to a fiber wallpaper fabric with a thickness of 1.15-2.0 mm and heat treated, and then a desired pattern is printed by a gravure printing machine. The resulting product is dried by passing through a drying chamber at about 160-170 ° C. and then the final fibrous wallpaper product is wound up.

As such, the present invention relates to a deodorizing, antibacterial and phytoncide generating composition of a natural material that can be applied to a fiber wallpaper fabric, and when coated and impregnated a fiber wallpaper fabric, it can give an environmentally friendly function. It can provide an environmentally friendly high-performance fiber wallpaper composition that can generate a large amount of phytoncide material.

Sodium silicate is the common name for sodium metasilicate (Na ₂ SiO ₃ ) compounds, well known as water glass, liquid glass. It can be used in aqueous and solid phase and in cement, active fire protection, refractory, textile fabrics and wood processing and building interior materials. Sodium carbonate (Na ₂ CO ₃ ) and silicon dioxide (SiO ₂ ) are melted to produce sodium silicate and carbon dioxide.

Na ₂ CO ₃ + SiO ₂ → Na ₂ SiO ₃ + CO ₂ (1)

Anhydrous sodium silicate contains chained anions consisting of corners shared by (SiO ₄ ) tetrahedra rather than isolated (SiO ₃ ) ^2- .

In addition to the anhydride, there are many hydrates having a molecular formula of Na ₂ SiO ₃ · nH ₂ O (n = 5, 6, 8, 9) of SiO ₂ (OH) ₂ ^{2 −} separated tetrahedron anions. Commercially available sodium silicate pentahydrate (Na ₂ SiO ₃ · 5H ₂ O) is in the form of Na ₂ SiO ₂ (OH) ₂ · 4H ₂ O, and hexahydrate (Na ₂ SiO ₃ · 9H ₂ O) is Na ₂ SiO ₂ (OH) ₂ · 8H ₂ O.

additive: Sodium silicate

Liquid sodium silicate ( Sodium silicate )

Sodium silicate (sodium silicate) is the most widely used inorganic compound among water-soluble silicates. In general, the molecular formula of Na ₂ O-nSiO ₂ -xH ₂ O is also referred to as water glass because of its solubility in water. It shows various properties depending on the molar ratio and concentration of SiO ₂ / Na ₂ O and is used for various purposes. The molar ratio calculation of liquid sodium silicate is as follows.

Molar ratio of sodium silicate = weight ratio of SiO ₂ / Na ₂ O x 1.032

In general, sodium silicate is commonly used as a liquid, solid, crystal, or amorphous powder. The figure below is a state diagram of sodium silicate for Na ₂ O—SiO ₂ —H ₂ O.

<Structure>

In the sodium silicate solution, silicate ion monomers, polysilicate ions and colloidal silicate ion micelles are present together in various forms. Its form is known to depend on the SiO ₂ / Na ₂ O molar ratio and concentration. The figure below shows the relationship between the molar ratio and the molecular weight of liquid sodium silicate measured by the light scattering method.

<Melting point>

The melting point of silica sand (SiO ₂ ), which is a raw material of sodium silicate, is 1,710 ° C. and the melting point of sodium carbonate (Na ₂ CO ₃ ) is 849 ° C., but the melting point of solid sodium silicate is not apparent. As a rule, it starts to melt at 550-670 ° C and begins to flow at 730-870 ° C, and melts completely above 1,300 ° C.

<Weight>

The specific gravity of the liquid sodium silicate is generally expressed as bomedo (Be '). The relationship between boomedness and specific gravity is as follows.

Be '= 144.3 (d-1) / d or 144.3 / 144.3-Be'

Where Be 'is bomedo and d is specific gravity. When the temperature rises by 1 ° C, the bomedome falls by 0.04. The conversion equation of Bomedo according to the temperature change is as follows.

Be '(to) = Be' (t1)-(20-t1) × 0.04

Where Be '(t1) is the bomedome at temperature t1, and Be' (to) represents the bomedome at 20 ° C. The figure below shows the relationship between the mole ratio and the borome of liquid sodium silicate.

<Viscosity>

The viscosity of liquid sodium silicate depends on the molar ratio of SiO ₂ / Na ₂ O. At the same molar ratio it varies with concentration and temperature. When the concentration increases at the same molar ratio, the viscosity increases, and when the temperature rises at the same molar ratio and concentration, the viscosity drops rapidly. On the contrary, when temperature falls below 20 degreeC, a viscosity will rise rapidly.

<Freezing point>

Three kinds of liquid sodium silicate of Korean Industrial Standard KSM 1415 freeze at about -2.5 ℃, but one species with low molar ratio and high concentration does not freeze at -10 ℃. The liquid sodium silicate with its medium molar ratio and bome degree of about 50 freezes at minus 5-8 ° C. Products with a molar ratio of 1.8 or less are inversely subject to crystals and not to freeze. In the case of sodium orthosilicates having a molar ratio of 0.5, hydrated crystals are formed even at room temperature.

<pH>

The pH of the liquid sodium silicate is in the alkaline region and generally depends on the molar ratio and concentration.

<Reaction with Acid>

When acid is added to the liquid sodium silicate, the pH is lowered by the neutralization reaction, and polymerization (siloxane bond) of the silicate ions or polysilicate ions proceeds to increase the viscosity. Proceed further to gel.

_{Na 2 O · nSiO 2 + H} 2 SO 4 + (m-1) H 2 O → nSiO 2 · mH 2 O + Na 2 SO 4

The increase in viscosity and the rate of gelation depend on the type of acid, the amount of acid added, the concentration of the solution, the temperature and the like.

Reaction with metal ions

Liquid sodium silicate reacts with metal ions such as Ca, Mg, Al, and Ba to simultaneously form an insoluble silicate metal hydrate, silicate metal hydroxide, silicate, and the like and gelate.

_{Na 2 O · nSiO 2 + Ca} (OH) 2 + mH 2 O → CaO · nSiO 2 · mH 2 O + 2NaOH

The silicate compound produced by such a reaction depends on the amount of metal ions and silicate ions present.

<Reaction with Organic Compound>

Both polyhydric alcohols such as glyoxal and ethylene glycol diacetate and acetate esters produce glycolic acid or acetic acid in the presence of alkali and gelate sodium silicate by neutralization. Although organic solvents, such as methyl alcohol, ethyl alcohol, and acetone, are gelatinized, they are simply dehydrated and dissolved again when water is added.

<Hardening by Dehydration>

Sodium silicate also gels with alcohol. This is the polymerization of SiO ₂ tetrahedron with dehydration of H ₂ O in sodium silicate as binding water, resulting in a firm film. Dehydration of 100% is impossible if it is not more than 1,000 ℃, the process is vitrified at 600-1,000 ℃ through the porous at 120-500 ℃. 95% dehydration is carried out at 200 ° C, and further dehydration proceeds very slowly. Dehydration does not change the solubility in water.

Liquid Sodium silicate  main purpose

Adhesive and Cement

Liquid sodium silicate is used as an adhesive for paper tubes, paper and many other materials. Liquid sodium silicate is an economical adhesive with excellent initial workability, adhesion and adhesive strength. The advantage of liquid sodium silicate is that the surface of the adherend is easily wetted and the permeability and viscosity can be adjusted to achieve good adhesion and strength. Liquid sodium silicate is of particular value as an adhesive because its loss can change from a liquid to a semisolid state with only a small loss of water. Due to this property, adhesion occurs quickly and is suitable for high speed automatic bonding machine work for paper products requiring initial adhesion.

In addition, various types of cement can be produced by changing the molar ratio of liquid sodium silicate and using it for cement mixing. Such cement is used for acid-resistant structures, the production of refractory materials, binders for thermal insulation materials and the like. It is also used to attach metal to glass and ceramics. The use of liquid sodium silicate in cement mixing has the advantage of imparting acid resistance, heat resistance and water resistance to the cement. In addition, cement mixed with liquid sodium silicate is easy to operate and economical and adheres well to any surface.

<Pulp and paper>

In the paper and paper industry, liquid sodium silicate is used as a de-inking, sizing, coating, and bleaching agent. Liquid sodium silicate has been used for a long time in fiber bleaching with hydrogen peroxide. With proper stabilization of heavy metal ions, enzymes and other processing impurities, hydrogen peroxide is a good and economical bleach and works best when the treatment solution is buffered correctly in the alkaline pH range. Sodium silicate is an effective and economical stabilizer and is used as a buffer.

Synthetic detergent and fiber

Many synthetic detergents use sodium silicate in the form of liquid or dried granules. The range of applications ranges from metal cleaning, textile industry, laundry and deinking of paper to bowls, dairy equipment, bottles, floors and engine cleaners. Synthetic detergent use has increased very quickly. In the early stages of use, detergents were used alone, and then phosphate and other builders were used to increase detergent performance. However, when these detergents were used for home use, serious side effects were found. That is, the detergent component corrodes the metal alloys used in aluminum, zinc, and other washing machines, and also damages the enamels and glazes of magnetic products. The use of sodium silicate solved this problem. Many new synthetic detergents continue to be introduced, but sodium silicate still plays its role.

<Gel, catalyst>

Silica gel is made by treating liquid sodium silicate with acid. The resulting silicic acid precipitate is then washed to remove the water soluble salts and to dry. In the manufacture of silica gel, silicates with high molar ratios are generally used. The final product is a glassy particle with numerous pores inside it that can adsorb moisture as well as other substances. Because of this property, silica gel is used to purify dehumidifying agents, juices and beer. Specially made silica gel is also used to make insulating materials.

Related to silica gel is amorphous silica powder. Amorphous silica powder is added to rubber products to increase wear resistance. In other applications, it is used as an extender for inks, plastics, varnishes, dispersants for paints, powders for spraying, and additives for preventing aggregation of insecticides.

Liquid sodium silicate reacts with an aqueous solution of many water soluble salts to form a complex gelled precipitate. For example, aluminum salts react with liquid sodium silicate to form sodium-aluminum silicate gels. It can be used to make a material suitable for water softening.

In addition, catalyst materials are made by synthesizing other materials on silica gel. The most widely used of these are silica-alumina type catalysts. Precisely synthesized and dried silica-alumina catalysts play various roles in the petrochemical industry, such as the production of high octane gasoline. Silica gel produced by synthesis or precipitation with various other components is used for oxidation of organic compounds, pyrolysis of petroleum hydrocarbons, oxidation of sulfur dioxide to sulfur trioxide, and the like.

Similar to silica gel catalysts are molecular sieves. They are made by reacting various salts such as sodium silicate and sodium-aluminum salts. Molecular sieves have a crystal structure and can control internal pore size. Molecular sieves have excellent properties that can serve to separate or filter out mixtures of molecules of different sizes.

additive: Potassium silicate

Liquid Potassium silicate

Potassium silicate (carilicate) is the most widely used inorganic compound with sodium silicate among water-soluble silicates. As a compound whose physical properties change depending on the molar ratio and concentration of SiO ₂ / K ₂ O, it is used in various fields. The molar ratio calculation of liquid potassium silicate is as follows.

Molar ratio of potassium silicate = weight ratio of SiO ₂ / K ₂ O x 1.568

Because of its various properties, potassium silicate is used in the fields of welding rods, pulp stocks, soaps and detergents, and paints. Potassium silicate is mainly in aqueous solution. In many applications potassium silicate performs better than sodium silicate (sodium silicate). For example, in the flux coating of electrodes, potassium silicate creates a soft arc and burns quietly. Because of its high solubility and compatibility with other components, potassium silicate is suitable for liquid deodorization.

Potassium silicate is also free from effloresce, making it ideal for use in paints, coatings and binders. The viscosity of potassium silicate varies with the ratio of silica to potassium oxide, or alkalinity, solids. That is, the viscosity decreases when both alkalinity and solid content decrease. In addition, the viscosity changes depending on the water content in the solution and the solution temperature. Viscosity is greatly affected by relatively small changes in the water content in the solution.

Potassium silicate improves wettability and detergency. Potassium silicate can be used to make liquid deodorant with excellent storage stability. Potassium silicate foams well in liquid and semi-solid soaps, effectively disperses dirt and prevents re-contamination. Potassium silicate provides higher solubility and miscibility than sodium silicate.

Potassium silicate can also be used in the preparation of special catalysts where sodium ions should be free. The high fire resistance of potassium silicate is used in textile wallpaper, wall materials, paper and the like. It can be used to mix silica powder with clay.
