Description

Non-catalyst hardening coating composition including organic methal, method of the same and coating product hence

 The present invention relates to a coating composition, more specifically, an organometallic-containing coating composition containing an organometallic, which does not induce a gelation reaction at room temperature, which can be stably stored, and can form a coating film at room temperature, and a method for preparing the same. It relates to a coated product.

Color-coated aggregates are applied to the surfaces of metals, urethanes, and asphalt, etc., which are used as roofing materials or exterior wall materials among building exterior materials, for the purpose of making the aesthetics of building structures colorful and preventing oxidation of organic materials and corrosion of metals.

In general, color aggregates are coated with ceramics having excellent durability, chemical resistance, weather resistance, and heat resistance to aggregates obtained by crushing natural stone, artificial stone, or sintered stone to a certain particle size, and are used for construction structures or civil engineering. Such color aggregates are required to be environmentally friendly with excellent water resistance, alkali resistance, heat resistance, abrasion resistance and gloss.

Conventional color aggregate is usually manufactured by heat treatment at a temperature of 300 ° C. to 700 ° C. for a sufficient time of 1 hour or more, and it is necessary to lower the heat treatment temperature and time to reduce production costs. In addition, the conventional color aggregate has a problem in severe color change when exposed to the air for a long time due to the limitation in weather resistance. In this way, the color aggregate has a lot of changes in the physical properties depending on the aggregate used, the type of binder, or the heat treatment conditions, in particular, the color of the color aggregate is largely dependent on the raw materials used.

According to US Pat. No. 4,378,408, aluminosilicate group minerals, which are widely used as binders for color aggregates, serve as fillers, water reducing agents and insolubilizers for alkali metal silicates in coatings. However, when the amount of aluminosilicate group minerals used increases, the glossiness decreases, and in particular, it is difficult to predict a desired color due to the large change in color after heat treatment due to impurities such as iron oxide contained in the aluminosilicate group minerals. Because of this, it is difficult to produce a variety of color aggregates, and there was a problem in particular difficult to display a bright color.

In addition, although a small amount of hardener is added to improve the water resistance of the alkali metal silicate used as the binder, satisfactory water resistance cannot be obtained. When a large amount of hardener is added to increase the water resistance, the formation of gel increases and the color change increases. There was a problem that the adhesion strength with the aggregates is lowered.

In order to solve this problem, Korean Patent Application No. 2000-12551 discloses a mixture of an alkali metal silicate with a substance such as sodium citrate in one selected from silica sol, alumina sol, and a mixture of the two alumino silicate minerals. A binder is prepared by adding a curing agent, etc., and a coating composition is prepared by adding a colorant and water to the binder, and then coating the surface of the aggregate with the coating composition while injecting hot air at 40 to 120 ° C. into the mixer. In addition, by manufacturing a color aggregate by heat-treating the aggregate coated with the coating composition at 60 ~ 1000 ℃ in the furnace, the production cost is reduced because it is produced by performing a heat treatment for a short time at a lower temperature than conventional, and has been used conventionally By using silica sol, alumina sol or a mixture of the two in place of the aluminosilicate mineral Easy color adjustment of a color aggregate, and discloses an aluminosilicate group that is excellent in water resistance, weather resistance and heat resistance compared with the conventional color effect aggregate who use color mineral aggregate and a method of manufacturing the same

However, this patent, which discloses a method for producing a colored aggregate by coating over two times based on alkali metal silicate, still does not solve the problem that alkali metal silicate is weak in water resistance.

That is, typical water glass of alkali metal silicate (eg, Na ₂ O—SiO _{2 type} ) is hydrophilic and easily soluble in water. In addition, the dried gel body is changed to a wet gel body by prolonged immersion. That is, even if the water glass containing the pigment is spray-coated to the aggregate and dried, peeling of the color due to immersion is inevitable. Various studies have been conducted to improve this problem, but water glass-based coating liquids having excellent water resistance have not been commercialized. This is because water glass readily dissolves in water and gels rapidly for solutions with low hydrogen ion concentrations (acid solutions), and especially with alcohols. In order to solve this problem, heat treatment of 600 ℃ or higher is required, and as a result, the production price increases.

Since the present invention has been made to solve the above-mentioned problems, an object of the present invention is to provide an organic metal that can form an excellent coating film even if it is naturally dried or rapidly dried by hot or cold air without requiring a long time heat treatment in an electric furnace or the like. It is to provide a coating composition, a production method thereof and a coating product thereby.

Another object of the present invention is to provide an organometallic-containing coating composition, a method for producing the same, and a coating product thereof, which can be stably stored and can be formed without a catalyst even at room temperature without gelation reaction induced at room temperature.

Still another object of the present invention is to provide a product coated to have an excellent coating film at low cost since it forms an excellent coating film without a heat treatment at room temperature without a separate heat treatment.

The terms used in the present invention were selected as general terms as widely used as possible, but in some cases, the terms arbitrarily selected by the applicant are included. In this case, the meanings described or used in the detailed description of the present invention are considered, rather than simply the names of the terms. The meaning should be grasped.

Hereinafter, the technical structure of the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Like reference numerals designate like elements throughout the specification.

Coating compositions of the present invention include silicon alkoxides, deionized water, alcohols, DMF or formamide, fumed silica, and in some cases hydroxypropyl cellulose (HPC), metal nitrates or metal chlorides or metals Any one of the alkoxide pigments, pigments or foaming additives may be further included.

First, when the organometallic-containing coating composition of the present invention forms a coating film, that is, bonding to an oxide substrate or a metal substrate, H ₂ O is separated from SiOH on the surface of the substrate and OH of the coating liquid and -Si (in the substrate). This is because a bond of -OM (metal atom of the coating liquid)-type is formed. In addition, in the metal base, a bond of the type -MO-M '(metal atom of the metal base)-is formed. These bonds have short-range or long-range regularity and are amorphous in solution and form nano-sized. The nanoscale molecular groups are hydrogen bonded to pigments or pigments or surrounded by coating particles to cure together upon drying.

That is, the main chemical reaction formula of the organometallic-containing coating composition of the present invention,

Si (OR) ₄ + R'OH → R'Si (OR) ₃ + H ₂ O (substitution)

R'Si (OR) ₃ + H ₂ O → R'Si (OH) ₃ + ROH + H ₂ O (hydrolysis)

R'Si (OH) ₃ → 2R'Si (OH) ₃ (polymerization),

의 화학구조에 첨가되는 다른 금속원자가 산소를 일부 공유하여 상기 유기금속함유코팅조성물은 안정된 sol 상태를 유지한다.ultimately

The organometallic-containing coating composition maintains a stable sol state because other metal atoms added to the chemical structure of the part share oxygen.

The gelation reaction is induced at room temperature through DMF or formamide, or fumed silica, which is further included in the basic structure, and in some cases, hydroxypropyl cellulose (HPC), metal nitrate or metal chloride or metal alkoxide, pigment, etc. It can be stored stably, and is applied to the substrate to be coated in a thickness of several nm to several tens of micrometers to form a solid ceramic coating film at room temperature or below 500 ° C.

The silicon alkoxide contained in the organometallic-containing coating composition of the present invention is preferably included in 1 ~ 35wt%, the content is less than 1% by weight, the adhesion to the substrate is significantly lowered, if exceeding 35% by weight is excessive This is because alcohol and deionized water are required. In particular, the silicon alkoxide used in the present invention is useful because it is cheaper than other metal alkoxides and mass produced in Korea.

In addition, the deionized water in the organometallic-containing coating composition of the present invention is preferably contained in 10 ~ 80wt%, less than 10wt% there is a problem that the gelation of the coating composition is faster, when the coating film is dried more than 80% by weight This is because the adhesive strength after the fall.

In the organometallic-containing coating composition of the present invention, it is preferable to include alcohol in an amount of 1 to 40 wt%. If it is less than 1 wt%, it is difficult to obtain a homogeneous sol solution by partial hydrolysis of silicon alkoxide. This is because there is a problem not involved in the reaction.

In addition, the DMF or formamide contained in the organometallic-containing coating composition of the present invention is preferably 0.1 ~ 10wt%, less than 0.1wt% has a drying delay effect is less than the above range because the drying time is too long in the range to be. In other words, if the drying speed is too fast, the film is not dense and it is difficult to have adhesion strength. On the contrary, if the film is too slow, the film thickness at the room temperature is not homogeneous and staining occurs. Full control of the drying speed is very important in the process of forming the membrane because it depends entirely on the dehydration time. The coating composition of the present invention can improve the drying rate and the degree of densification of the membrane by DMF or formamide.

The organometallic-containing coating composition of the present invention may further contain fumed silica in an amount of 0.0001 to 1wt%. If the amount is less than the minimum amount, it is difficult to obtain a desired effect. This is because the shelf life is poor for more than a month.

Here, fumed silica not only adjusts the glossiness of the coating composition of the present invention through the matting effect or compensates for the insufficient silicon content, but also reacts with water to form Si-OH groups on the surface of particles easily to disperse into nano-sized particles. So it can play a seed role in the coating composition. In addition, while increasing the adhesion of the coating composition can also improve the drying speed.

On the other hand, in order to control the viscosity of the coating composition, the organometallic-containing coating composition of the present invention preferably comprises hydroxypropyl cellulose (HPC) at 0.001 ~ 5wt%, less than 0.001 almost no change in viscosity and more than 5wt% There is a problem of causing peeling with the substrate during drying.

In addition, the organometallic-containing coating composition of the present invention preferably contains 0.001 to 5wt% of metal nitrate or metal chloride or metal alkoxide in order to improve heat resistance together with adhesion of the coating film. If there is little and exceeds the maximum amount, the crystallized metal-OH (eg, calcium hydroxide, aluminum hydroxide, sodium hydroxide, etc.) precipitates when the coating composition is dried, thereby decreasing transparency and color development.

Here, since metal chloride forms hydrochloric acid in aqueous solution, metal nitrate is more preferably used because chlorine gas is generated during coating. In addition, metal alkoxides are generally more expensive than metal chlorides and metal nitrates, and because of their ease of gelation (because of increased reactivity with other cations) when mixed with silicon alkoxides, special care must be taken when using them.

Aluminum nitrate (Al-nitrate) was used as the metal nitrate in the following examples, but not limited thereto. Other metals such as B, Zr, Mn, and Ti may be used. The use of the metal nitrate in the coating composition of the present invention is because the purpose of sharing the Si and oxygen to combine in the aqueous solution and change its properties (heat resistance, wear resistance, refractive index, etc.).

In addition, the organometallic-containing coating composition of the present invention may further comprise a pigment (Pigment) in 0.001 ~ 10wt% according to the use, preferably a small amount of the type of precipitation is not dispersed in the coating composition of the present invention Pigments are used. That is, since the pigment is intended to express color, the transparent coating composition has a pigment usage of 0% by weight, and when the pigment is used in excess of 10wt% for coloring, the storage stability of the coating composition is lowered and the usage of silicon alkoxide is increased. This is because there is a problem that is not economic.

In addition, the organic metal-containing coating composition of the present invention is a foamable organic compound (for example, Urea) 0.001 to 5% by weight to decompose into a gas at 70 ℃ to 250 ℃ as a foaming additive in order to have a flame-retardant and thermal insulation performance of the coated surface It is preferred that more is added.

The organometallic-containing coating composition of the above composition comprises the steps of preparing a primary solution by stirring alcohol and silicon alkoxide; Preparing a secondary solution by stirring deionized water, DMF or formamide, and fumed silica; It can be prepared by mixing the primary solution and the secondary solution by stirring until it is transparent to prepare a coating solution. In this case, the method may further include a step of preparing a tertiary solution by stirring any one of deionized water and metal nitrate, metal chloride or metal alkoxide, followed by stirring with the coating solution.

That is, the primary solution is stirred by adding alcohol to the stirring vessel and then adding the silicon alkoxide, it is preferable to stir at about 500rpm for 1 hour. At this time, the alcohol may include 1 to 40% by weight, and the silicone alkoxide may include 1 to 35% by weight.

In addition, the secondary solution is stirred by adding DMF or formamide, deionized water, fumed silica, preferably stirring at 300 rpm or more at room temperature for 2 hours. At this time, it is preferable that 0.1 to 10% by weight of DMF or formamide, and 0.0001 to 1% by weight of deionized water is 10 to 80% by weight fumed silica. In some cases, additional HPC may be added during the preparation of the secondary solution, followed by stirring until the solution becomes transparent. The HPC is preferably included in an amount of 0.001 to 5% by weight.

The primary solution and the secondary solution prepared as described above may be stirred until it becomes transparent to prepare a coating solution, that is, the coating composition of the present invention.

In some cases, metal nitrate, metal chloride or metal alkoxide is added to deionized water, followed by stirring for 15 minutes to prepare a tertiary solution, followed by mixing with a primary solution and a secondary solution to carry out agitation. An organometallic-containing coating composition may be prepared. In the following examples, a method of obtaining a coating solution by further adding a tertiary solution and stirring the primary solution and the secondary solution was described, but the order may be different depending on the case.

At this time, one or more pigments or effervescent additives may be added to the organometallic-containing coating composition, depending on the intended use. When the pigment is added, the pigment may be used to prepare colored aggregates by coating aggregates, or urea. Adding a foamable additive comprising a can exhibit a flame retardant and thermal insulation performance. That is, when the surface coated with the organometallic-containing coating composition further comprising a foamable additive is exposed to fire or high heat, the surface is swollen.

Therefore, when the organic metal-containing coating composition of the present invention is coated on the surface of ceramic tile, glass, metal, and the like, a water-repellent coating film is formed without a catalyst even at room temperature, thereby improving pollution resistance, chemical resistance, abrasion resistance, and mechanical strength. .

As a result, the organometallic-containing coating composition of the present invention can be used in all articles intended to provide an inorganic coating which can improve the color or waterproof and surface protective film formation or flame retardancy or pollution resistance, chemical resistance, abrasion resistance and mechanical strength, In particular, it can be used for interior and exterior building materials.

For example, when the organic metal-containing coating composition of the present invention is used in the production of color aggregates, the aggregates are color-coated with the organic metal-containing coating composition without a catalyst at room temperature, so that the organic metal-containing coating composition adheres well to the aggregate surface. It is possible to produce excellent color aggregate even if selected and dried any of natural drying, hot air drying or cold air drying without a heat treatment step. Therefore, by the present invention it is possible to produce a high quality color aggregate at a low production cost.
