Definitions
- This invention pertains to inorganic-ceramic-coating-composition which can be harden under normal temperature and a method for manufacturing thereof. More specifically, it pertains to a inorganic-ceramic-coating-composition which can be harden under normal temperature that is created by compounding functional fillers that improve physio-chemical characteristics of film, inorganic color powders, and other functional additives that may enhance other functionality in the inorganic solution that is made by having one or more organo-silanes and water that contains one or more SiO particles in nano or micro size react with each other, and by hydrolyzing and condensation-polymerizing the reacted matter.
- the above-mentioned "Which can be harden under normal temperature” refers to the feature by which a composition hardens even when it is left under normal temperature without an additional high temperature-plasticizing process.
- paints or coatings aim to beautify and extend the lifespan of structures or buildings, and to preserve them for a long time by protecting them. Accordingly, paints or coatings should well represent gloss and color (in terms of design); should be easy to use and free of smell (during painting); should be able to preserve painting or coating layers for a long time; should have high chemical resistance (solvent resistant, chemical resistant, weather resistant, water resistant, antibacterial); should have physically good features (nonflammable, flame retardant, waterproof, adhesive strength, insulation); and should be innoxious to human body and environmentally safe.
- This invention created in order to resolve the problems mentioned above aims to provide a inorganic-ceramic-coating-composition which can be harden under normal temperature and a method for manufacturing thereof, which may prevent cracks through the flexibility given by functional additives, thus solving the problem of not being able to paint thickly.
- compositions of the inorganic-ceramic-coating-composition which can be harden under normal temperature in this invention, which is created in order to accomplish the above-mentioned objectives, are the following: 60-70wt% of hydrolyzed and condensation-polymerized inorganic solution that is made by having one or more organo-silanes and water that contains one or more SiO particles in nano or micro size react with each other; 15-20wt% of functional fillers that are chosen from either potassium titanate or alumina, or the compound thereof; 3-8wt% of color powders made of oxidized steel; and 2-22wt% of functional additives that are chosen from either tourmaline or rare-earth ore, or the compound thereof.
- Phase I - compound one or more 100wt% organo-silane and 35-45wt% silica sol, stir it at 40-50 0 C for 5-10 minutes, making inorganic solution in sol state;
- Phase II Phase II - put 60-70wt% of the inorganic solution generated in Phase I, 15-20wt% functional fillers, which are selected from potassium titanate or alumina, 3-8wt% of color powders made of oxidized steel, 2-22wt% of functional additives that are selected from either tourmaline or rare-earth ore, or the compound thereof and stir the mixed solution;
- functional fillers which are selected from potassium titanate or alumina, 3-8wt% of color powders made of oxidized steel, 2-22wt% of functional additives that are selected from either tourmaline or rare-earth ore, or the compound thereof and stir the mixed solution;
- Phase III put the solution stirred in Phase II in a homogenizer; stir it at a high speed for 1-2 hours to homogenize the particles;
- Phase IV - have the homogenized matter pass through a 325-1000 mesh net and extract the filtered particles.
- the most important feature of this invention is that an easy hardening is possible in normal temperature condition without an additional high-temperature plasticizing process.
- the features include a good representation of gloss or color, easy to use, absence of smell owing to exclusion of organic matters, chemical and physical resistance that enables longtime preservation, not harmful to human body, and environmental safe.
- composition reduces the occurrence of the sick house syndromes by screening harmful substances such as VOCs or formaldehydes, and since all of the elements are inorganic, environmental pollutions are minimized even after it is removed and it may maintain semi-permanent state, resulting in long life.
- Alkoxysilane is represented with a molecular formula "RnSi(OR') ". "R”
- 4-n represents an alkyl group, including methyl group, ethyl group, phenyl group, CF CH CH CH , CF (CF ) CH CH , CF (CF ) CH CH , and "OR" as hydrolyzed alkoxysilane is hydrolyzed by water or moisture in the air, or moisture on the surface of materials, creating a silanol group (Si-OH), which strongly bonds with the surfaces (M-OH) of the materials through Si-O-M bond.
- Si-OH silanol group
- the stable inorganic part composed of silicon-oxygen has higher bond energy than other bonds as shown in the table. It has not only the features of weather resistance, chemical resistance, abrasion resistance, high solidity, which silicon retains, but also the features of cold resistance and tolerance to repeating heat shock owing to the flexibility and resilience of the silicon-oxygen bond.
- organo-silane forms an inorganic solution through hydrolysis and condensation polymerization under the presence of silicon dioxide (SiO ).
- SiO silicon dioxide
- the inorganic solution has a silanol group, and this group generates Si-O-M bond, which has strong bond strength. Because of this, the inorganic solution itself can play the role as a strong binder.
- the inorganic solution is formed by compounding 100wt% of organo-silane, in particular, either methyl trimethoxy silane or tetraethoxysilane, or the compound thereof, with 35-45wt% of silica sol and by stirring it.
- organo-silane in particular, either methyl trimethoxy silane or tetraethoxysilane, or the compound thereof
- silica sol may weaken the Si-O-M bond, resulting in exfoliations at a high-temperature. Accordingly, it is desirable to compound within the above range.
- adding one of methanol, ethanol, isopropanol, or alcohol mix may control the viscosity and the reaction speed of the solution.
- potassium titanate or alumina Al O
- Al O potassium titanate or alumina
- the particles of these materials are needle-shaped or plate-shaped, they may prevent cracks, control the viscosity of coatings, and enhance heat resistance, volume of far infrared ray, and abrasion resistance.
- these functional fillers are added with less than 15wt%, deterioration of gloss or adhesive strength may occur; and in case they are added with more than 20wt%, adverse effects of rough film surface may occur. Accordingly, it is desirable to keep the range of 15-20wt%.
- the inorganic-ceramic-coating-composition which can be harden under normal temperature in this invention may be used as a substitute of existing paints. To this end, it must represent a variety of color. Up to date, organic colors or pigments have been generally used in order to represent color. However, these organic matters may cause various problems as mentioned above. Accordingly, oxidized steel color is added in the normal temperature-hardening inorganic- ceramic-coating-composition in this invention in order to represent color to maintain the inorganic composition. It is desirable to contain 3-8wt% of color powders. In case color powders are contained with less than the range, color may not be represented properly; and in case color powders are contained with more than the range, det erioration of adhesive strength may occur.
- the inorganic-ceramic-coating-composition which can be harden under normal temperature in this invention may contain 2-22wt% of matter as a functional additive, to give the function of discharging far infrared rays or negative ions, if necessary.
- tourmalines and rare-earth ores are used as matters necessary to discharge negative ions or far infrared rays.
- tourmaline a kind of quartz porphyry, is a mineral that is permanently polarized. It discharges extremely small amount of negative ions at a still-state, but discharges large amounts of negative ions or far infrared rays as energy of temperature, friction, pressure, shock, or impact is applied from the outside.
- Organisms may have their tissues or chromosomes mutated or changed by its radiation. However, it has been found through clinical experiments of low-level radiation in the USA and Japan, that organisms may gain advantageous effects from low-level radiation.

Description
Description
AN INORGANIC-CERAMIC-COATING-COMPOSITION
WHICH CAN BE HARDEN UNDER NORMAL TEMPERATURE
CONDITION AND A METHOD FOR MANUFACTURING
THEREOF Technical Field
[1] This invention pertains to inorganic-ceramic-coating-composition which can be harden under normal temperature and a method for manufacturing thereof. More specifically, it pertains to a inorganic-ceramic-coating-composition which can be harden under normal temperature that is created by compounding functional fillers that improve physio-chemical characteristics of film, inorganic color powders, and other functional additives that may enhance other functionality in the inorganic solution that is made by having one or more organo-silanes and water that contains one or more SiO particles in nano or micro size react with each other, and by hydrolyzing and condensation-polymerizing the reacted matter. Here, the above-mentioned "Which can be harden under normal temperature" refers to the feature by which a composition hardens even when it is left under normal temperature without an additional high temperature-plasticizing process.
[2]
Background Art
[3] Generally, paints or coatings aim to beautify and extend the lifespan of structures or buildings, and to preserve them for a long time by protecting them. Accordingly, paints or coatings should well represent gloss and color (in terms of design); should be easy to use and free of smell (during painting); should be able to preserve painting or coating layers for a long time; should have high chemical resistance (solvent resistant, chemical resistant, weather resistant, water resistant, antibacterial); should have physically good features (nonflammable, flame retardant, waterproof, adhesive strength, insulation); and should be innoxious to human body and environmentally safe.
[4] Since existing traditional paints for construction are made by compounding various chemicals with organic matter that is extracted from crude oil, most of them contain organic matter. Because of this, with time, microorganisms propagate in fine cracks th at form on the painting layers, resulting in sporadic exfoliations. Continuous exposure to ultraviolet light results in discoloration, and since they are weak to heat, their flame resistance capability is low.
[5] In addition, since most paints contain various pollutant materials that are harmful to human body, such materials may cause environmental diseases that are classified as the sick house syndromes such as atopic dermatitis, headache, and vomiting.
[6] Furthermore, as oil reserves are limited and the amount of oil use has rapidly increased, supplying raw materials to produce paints is becoming difficult by the day.
[7] On the other hand, various ceramic paints offered as a solution to the above mentioned problems are largely composed of four elements including binders, colors or pigments, solvents, and additives. Since existing ceramic paints use resinous organic polymers as binders, or organic solvents such as acetone, benzene, toluene, xylene, with organic additives, these paints have not completely resolved the problems of the traditional paints.
[8] In addition, existing paints or coatings including ceramic paints are so inflexible that severe cracks develop and it is difficult to use thick paints or coats. Also, they need to be plasticized in high temperature by adding strong heat.
[9]
Disclosure of Invention Technical Problem
[10] This invention created in order to resolve the problems mentioned above aims to provide a inorganic-ceramic-coating-composition which can be harden under normal temperature and a method for manufacturing thereof, which may prevent cracks through the flexibility given by functional additives, thus solving the problem of not being able to paint thickly.
[H]
Technical Solution
[12] The compositions of the inorganic-ceramic-coating-composition which can be harden under normal temperature in this invention, which is created in order to accomplish the above-mentioned objectives, are the following: 60-70wt% of hydrolyzed and condensation-polymerized inorganic solution that is made by having one or more organo-silanes and water that contains one or more SiO particles in nano or micro size react with each other; 15-20wt% of functional fillers that are chosen from either potassium titanate or alumina, or the compound thereof; 3-8wt% of color powders made of oxidized steel; and 2-22wt% of functional additives that are chosen from either tourmaline or rare-earth ore, or the compound thereof.
[13] Here, it is desirable to include 3-5wt% of titanium oxide in 1-lOOnm in the functional additives in order to give photocatalysis.
[14] In addition, it is desirable to use either methyl trimethoxy silane or tetraethoxysilane, or the compound thereof, for the above-mentioned organo-silanes.
[15] The method for manufacturing inorganic-ceramic-coating-composition which can be harden under normal temperature is the following:
[16] Phase I - compound one or more 100wt% organo-silane and 35-45wt% silica sol, stir it at 40-500C for 5-10 minutes, making inorganic solution in sol state;
[17] Phase II - put 60-70wt% of the inorganic solution generated in Phase I, 15-20wt% functional fillers, which are selected from potassium titanate or alumina, 3-8wt% of color powders made of oxidized steel, 2-22wt% of functional additives that are selected from either tourmaline or rare-earth ore, or the compound thereof and stir the mixed solution;
[18] Phase III - put the solution stirred in Phase II in a homogenizer; stir it at a high speed for 1-2 hours to homogenize the particles; and
[19] Phase IV - have the homogenized matter pass through a 325-1000 mesh net and extract the filtered particles.
[20] Here, it is desirable to control the viscosity and reaction speed of the solution by adding one of methanol, ethanol, isopropanol, or alcohol mix in Phase I.
[21] In addition, it is desirable to add 3-5wt% of titanium oxide in 1-lOOnm in the
2-22wt% of functional additives in Phase II. Advantageous Effects
[22] In regards to the above-mentioned characteristics paints or coatings must possess, the inorganic-ceramic-coating-composition which can be harden under normal temperature has more advanced features than any other paints or coatings.
[23] The most important feature of this invention is that an easy hardening is possible in normal temperature condition without an additional high-temperature plasticizing process. In addition, the features include a good representation of gloss or color, easy to use, absence of smell owing to exclusion of organic matters, chemical and physical resistance that enables longtime preservation, not harmful to human body, and environmental safe.
[24] Furthermore, since the composition reduces the occurrence of the sick house syndromes by screening harmful substances such as VOCs or formaldehydes, and since all of the elements are inorganic, environmental pollutions are minimized even after it is removed and it may maintain semi-permanent state, resulting in long life.
[25] In addition, prevention of exfoliation and discoloration enables it to maintain beautiful outer appearance as it has tremendous heat resistance with inorganic elements. Also, because its raw materials are natural inorganic matters, supplying new materials runs smooth.
[26]
Best Mode for Carrying Out the Invention
[27] Before describing the inorganic-ceramic-coating-composition which can be harden under normal temperature, the following are the structure and principle of the inorganic solution, the starting material, as mentioned above.
[28] Alkoxysilane is represented with a molecular formula "RnSi(OR') ". "R"
4-n represents an alkyl group, including methyl group, ethyl group, phenyl group, CF CH CH , CF (CF ) CH CH , CF (CF ) CH CH , and "OR" as hydrolyzed alkoxysilane is hydrolyzed by water or moisture in the air, or moisture on the surface of materials, creating a silanol group (Si-OH), which strongly bonds with the surfaces (M-OH) of the materials through Si-O-M bond.
[29] As shown above, the stable inorganic part composed of silicon-oxygen has higher bond energy than other bonds as shown in the table. It has not only the features of weather resistance, chemical resistance, abrasion resistance, high solidity, which silicon retains, but also the features of cold resistance and tolerance to repeating heat shock owing to the flexibility and resilience of the silicon-oxygen bond.
[30] In this invention, organo-silane forms an inorganic solution through hydrolysis and condensation polymerization under the presence of silicon dioxide (SiO ). As described above, the inorganic solution has a silanol group, and this group generates Si-O-M bond, which has strong bond strength. Because of this, the inorganic solution itself can play the role as a strong binder.
[31] The inorganic solution is formed by compounding 100wt% of organo-silane, in particular, either methyl trimethoxy silane or tetraethoxysilane, or the compound thereof, with 35-45wt% of silica sol and by stirring it. In case the amount of silica sol deviates from the above range, it may weaken the Si-O-M bond, resulting in exfoliations at a high-temperature. Accordingly, it is desirable to compound within the above range.
[32] In the process of manufacturing an inorganic solution, adding one of methanol, ethanol, isopropanol, or alcohol mix may control the viscosity and the reaction speed of the solution.
[33] In addition, in order to improve the physio-chemical characteristics of the film formed by coatings, potassium titanate or alumina (Al O ) may be used as functional
2 3 filler. Since the particles of these materials are needle-shaped or plate-shaped, they may prevent cracks, control the viscosity of coatings, and enhance heat resistance, volume of far infrared ray, and abrasion resistance. In case these functional fillers are added with less than 15wt%, deterioration of gloss or adhesive strength may occur; and in case they are added with more than 20wt%, adverse effects of rough film surface may occur. Accordingly, it is desirable to keep the range of 15-20wt%.
[34] On the other hand, the inorganic-ceramic-coating-composition which can be harden under normal temperature in this invention may be used as a substitute of existing
paints. To this end, it must represent a variety of color. Up to date, organic colors or pigments have been generally used in order to represent color. However, these organic matters may cause various problems as mentioned above. Accordingly, oxidized steel color is added in the normal temperature-hardening inorganic- ceramic-coating-composition in this invention in order to represent color to maintain the inorganic composition. It is desirable to contain 3-8wt% of color powders. In case color powders are contained with less than the range, color may not be represented properly; and in case color powders are contained with more than the range, det erioration of adhesive strength may occur.
[35] In addition, the inorganic-ceramic-coating-composition which can be harden under normal temperature in this invention may contain 2-22wt% of matter as a functional additive, to give the function of discharging far infrared rays or negative ions, if necessary.
[36] Generally, tourmalines and rare-earth ores are used as matters necessary to discharge negative ions or far infrared rays. Of these, tourmaline, a kind of quartz porphyry, is a mineral that is permanently polarized. It discharges extremely small amount of negative ions at a still-state, but discharges large amounts of negative ions or far infrared rays as energy of temperature, friction, pressure, shock, or impact is applied from the outside.
[37] Rare-earth ore discharges negative ions even in a still-state, but as it is classified as a radioactive mineral, careful attention is required for safety when using it. Organisms may have their tissues or chromosomes mutated or changed by its radiation. However, it has been found through clinical experiments of low-level radiation in the USA and Japan, that organisms may gain advantageous effects from low-level radiation. Accordingly, it is possible to use radiation to the extent that it may not cause harm to the human body.
[38] When having the above-mentioned tourmaline or rare-earth ore included in the normal temperature-hardening inorganic-ceramic-coating-composition in this invention, it is important to use them appropriate to its usage. To use in an environment where there are continuous exterior effects, it is necessary to increase the portion of tourmaline. To use in an environment where there are little exterior effects, it is necessary to increase the portion of rare-earth ore. This adequate use ensures maximum discharge of far infrared rays or negative ions.
[39] In addition, titanium oxide may be included in the functional additives in order to give photocatalysis. As titanium oxide is activated by light, it can change various pollutants into innocuous matters.
[40] The inorganic-ceramic-coating-composition which can be harden under normal temperature is made through four phases that include : Phase I - "manufacturing
inorganic solution", Phase II - "stirring the mixed solution", Phase III - "homogenizing", and Phase IV - "extracting coatings".
[41] In Phase I, 35-45wt% of silica sol is compounded with one or more 100wt% of organo-silane, in particular, either methyl trimethoxy silane or tetraethoxysilane and, or the compound thereof, and the mixed solution is stirred at 40-500C for 5-10 minutes. The mixed solution of organo-silane and silica sol is exothermically reacted by chemical reaction, and it changes from a turbid state to a clean and transparent state while being reacted. Here, adding one of methanol, ethanol, isopropanol, or alcohol mix may control the viscosity and the reaction speed of the solution. The inorganic solution in sol state is made through these processes.
[42] In Phase II, 60-70wt% of the inorganic solution generated in Phase I, 15-20wt% of functional fillers, which are selected from either potassium titanate or alumina, or the compound thereof, 3-8wt% of color powders made of oxidized steel, and 2-22wt% of functional additives that are selected from either tourmaline or rare-earth ore, or the compound thereof are put in a reactor and the mixed solution is stirred, forming an inorganic-ceramic-composition.
[43] In Phase III, the solution stirred in Phase II is put in a homogenizer, and is stirred at a high speed for 1-2 hours to homogenize the particles.
[44] In Phase IV, the homogenized matter is passed through a 325-1000 mesh net and the filtered particles are extracted, completing the coating.
[45] In addition, it is desirable to add 3-5wt% of titanium oxide in 1- lOOnm in the
2-22wt% of functional additives in Phase II.
