Description

Refractory binder composition for lacquer module plates using natural lacquer}

The present invention relates to a refractory binder composition for a lacquer module plate (LMP) using natural lacquer, and more specifically, it is mixed with urushiol, a main component of lacquer, and applied to the plate by including inorganic oxides, polymers, minerals and polymer fibers. It relates to a refractory binder composition for a lacquer module plate using a natural lacquer solution that increases flame retardancy and fire resistance along with antibacterial and deodorizing functions of the lacquer module plate.

Natural lacquer is a paint that has been used for about 5,000 years. In addition to the features such as very high film strength, durability, and water resistance, natural lacquer has the characteristics of beautiful gloss and excellent touch.It was found on a ship that was destroyed in the Silla period of 1,000 years ago. The physical properties of woodware and furniture products can be confirmed in the case of maintaining their original form even after 1,000 years have passed. As such, lacquer is a paint that has been handed down from the East for thousands of years and is used not only for art crafts and lacquerware, but also for tableware, furniture, and windows.

The hardening of lacquer is hardened by wet drying by enzymatic reaction. Because of the action of these enzymes, the conditions of temperature and humidity are important when drying the coating film. The constituents of lacquer contain 60-65% of urushiol, and in addition, it contains a small amount of rubber (polysaccharide), nitrogen (protein), laccase (enzyme), and water. 2000)

In the existing traditional lacquer industry, the technology is handed down by a handful of craftsmen, and in particular, new materials and new manufacturing techniques have been introduced into the furniture, which was the main application item according to the change of the times, and the demand for it has rapidly increased as the mass production system was met. It has declined, and has continued its prestige as an expensive high-quality product only for traditional najeon lacquerware and cloisonné products.

In particular, it is true that many consumers have been neglected because of the allergies that occur during lacquering work, which is a unique characteristic of the product, and the unique smell of lacquer.

It is judged that the most decisive stagnation of the lacquer industry was from the introduction of kash in the 1970s-1980s, and the high-priced lacquer products are noticed in the market as kash lacquer applied for the purpose of replacing lacquer was mass-produced based on low price competitiveness. I didn't get it.

At present, it is more difficult to grow in related fields due to high-end functional paints and coatings, but the government and related local governments, as well as academia and industry, have begun to be interested in fostering and growing the purpose of modernization of traditional industries.

In particular, the reason why such lacquer is attracting new attention in the modern era is that as it is known as the most excellent natural rust inhibitor as a traditional material, the need for reliable and safe products to protect human health from environmental pollution, atopy, and environmental hormones has emerged. Because it became.

Accordingly, as disclosed in Korean Patent Application Publication No. 10-2019-0002995, the applicant developed a lacquer-coated module plate art-wall that can be used for building panels or interior walls, but there is a disadvantage that is vulnerable to fire resistance. Became.

Therefore, there is a need to develop a fire-resistant binder that can increase fire resistance without damaging the natural properties of lacquer in the lacquer module plate.

International Publication No. 2014/162718

The present invention is conceived to solve the above problems, and is mixed with urushiol, which is the main component of lacquer, and is applied to the plate by including inorganic oxides, polymers, minerals, and polymer fibers. Accordingly, it is flame retardant along with antibacterial and deodorizing functions of the existing lacquer module plate. And it is an object to provide a refractory binder composition for lacquer module plates using natural lacquer solution with increased fire resistance.

The present invention has the following features to achieve the above object.

The present invention includes at least one inorganic oxide selected from the group consisting of silica fume, blast furnace slag, fly ash, metakaolin, alumina, titania, and zirconia; One or more polymers selected from polyvinyl resins, polyester resins, polybasic acids, and polyhydric alcohols; One or more minerals selected from the group consisting of pearlite, vermiculite and diatomaceous earth; And one or more polymer fibers selected from the group consisting of polypropylene fibers, polyethylene fibers, cellulose fibers, PVA fibers, polyplane fibers, nylon fibers, acrylic fibers, glass fibers, carbon fibers and aramid fibers.

In addition, the inorganic oxide is used by mixing with water glass, which is an alkali stimulant.

In addition, the polymer contains 0.6 to 30 parts by weight based on 100 parts by weight of the inorganic oxide, and the polybasic acid is any one selected from Isophthalic acid, Terephthalic acid, Phth-alic anhydride, adipic acid, Sebasic acid, and Succinic acid, and the polyhydric acid The alcohol is any one selected from Ethylene glycol, Propylene glycol, butylene glycol, neopetyl gl-ycol, Hexylene glycol, Diethylene glycol, and Trimethylol propane.

According to the present invention, by including inorganic oxides, polymers, minerals, and polymer fibers, as they are mixed with urushiol, which is the main component of lacquer, and applied to the plate, there is an effect of increasing flame retardancy and fire resistance along with antibacterial and deodorizing functions of the existing lacquer module plate.

1 is a view showing examples of stirring between a refractory binder composition and urushiol according to an embodiment of the present invention.
2 is a view showing the results of combustion experiments of various lacquer module plates.

In order to explain the present invention, operational advantages of the present invention, and objects achieved by the implementation of the present invention, the following will illustrate a preferred embodiment of the present invention and look at it with reference.

First, terms used in the present application are only used to describe specific embodiments, and are not intended to limit the present invention, and expressions in the singular may include a plurality of expressions unless clearly different meanings in context. In addition, in the present application, terms such as "comprise" or "have" are intended to designate the presence of features, numbers, steps, actions, components, parts, or a combination thereof described in the specification, but one or more other It is to be understood that the presence or addition of features, numbers, steps, actions, components, parts, or combinations thereof, does not preclude in advance the possibility of being excluded.

In describing the present invention, when it is determined that a detailed description of a related known configuration or function may obscure the subject matter of the present invention, a detailed description thereof will be omitted.

The present invention provides a refractory binder composition comprising inorganic oxides, aggregates, polymers, minerals, and polymer fibers.

The present invention relates to an eco-friendly refractory binder composition that can be applied to a lacquer-coated module plate art-wall (LMPA) and has excellent flame retardancy and fire resistance, and contains inorganic oxides, polymers, minerals, and polymer fibers. Thus, it was possible to improve the flame retardant and fire resistance performance of the lacquer module plate with urushiol.

The inorganic oxide may be one or more selected from the group consisting of silica fume, blast furnace slag, fly ash, metakaolin, alumina, titania and zirconia, and more preferably, fine powder of blast furnace slag, an industrial by-product, is used. .

Blast furnace slag is an industrial by-product generated from blast furnaces of steel mills, unlike cement that emits a large amount of carbon dioxide during production. The blast furnace slag has a characteristic of latent hydrauric. Here, the term "latent hydraulicity" means that hydration reaction hardly occurs even when the powder itself is brought into contact with water, but the hydration reaction proceeds when an alkali stimulant is added. Therefore, the inorganic oxide of the refractory composition is characterized by using a mixture of blast furnace slag and water glass, which is an alkali stimulating agent.

In addition, the mixing ratio of the inorganic oxide and the alkali stimulant is preferably 1:0.01 ~ 1:1 weight ratio depending on the constituent components, and if it is out of the above range, it may cause deterioration of physical and chemical properties.

In addition, the polymer usable in the present invention is composed of any one or more selected from polyvinyl resin, polyester resin, polybasic acid or polyhydric alcohol, and the polyester resin is a condensation polymerization of polybasic acids and polyhydric alcohols. As a result, it is preferable that it is a medium and high molecular compound having an Ester Group in the main chain, and the polybasic acid may be composed of any one selected from Isophthalic acid, Terephthalic acid, Phth-alic anhydride, adipic acid, Sebasic acid, and Succinic acid. .

In addition, the polyhydric alcohol is any one selected from Ethylene glycol, Propylene glycol, butylene glycol, neopetyl gl-ycol, Hexylene glycol, Diethylene glycol, and Trimethylol propane.

Since the polymer fills relatively large pores and forms an organizational structure that creates a continuous polymer film, it can be said that resistance to absorption and permeation is improved as the polymer increases.

As the mineral material, at least one selected from the group consisting of perlite, vermiculite and diatomaceous earth may be used, and more preferably perlite is used.

When the pearlite ore is pulverized to 8 to 12 mesh or less and a high heat of 1,000°C or higher is rapidly applied, the volatile components contained in the pearlite gasify and expand inside the softened particles to form internal pores. What formed on the surface of the particles expands to about 10 to 20 times the original volume of pearlite as it ejects out. Because of this, expanded pearlite has a light specific gravity and is innumerable porous, and is connected by point contact between powders, so that the solid heat conduction of the pearlite itself is very small, and the pores between the pearlite particles are filled with fine particles to prevent convection, as well as radiation because the pearlite particle color is white. Insulation properties for the are also excellent.

In the present invention, it is preferable that pearlite has a specific gravity of 0.1 to 0.35, and when the specific gravity of pearlite is less than 0.1, there is a concern that the strength of the composition decreases and durability decreases, and when the specific gravity is 0.35 or more, heat conduction increases and the thermal insulation performance decreases. There is a fear of doing it.

In addition, the polymer fiber is one or more selected from the group consisting of polypropylene fiber, polyethylene fiber, cellulose fiber, PVA fiber, polyplane fiber, nylon fiber, acrylic fiber, glass fiber, carbon fiber and aramid fiber.

In addition, the polymer fiber is preferably included in an amount of 0.01 to 5% with respect to the volume of the total composition, and when used less than this, the performance is poor, whereas when used more than this, the aggregation or effect of the fiber is insufficient.

The use of polymer fibers has the effect of controlling tensile stress and cracking, increasing toughness, increasing resistance to impact, abrasion, and fatigue, and reducing fracture of the module plate due to fire.

In addition to the above components, the composition of the present invention may further include one or more compounds selected from the group consisting of water, a superplasticizer, a high-performance water reducing agent, an antifoaming agent, and a shrinkage reducing agent. In addition, as the superplasticizer, a powder-type superplasticizer may be used, and more preferably, a polycarboxylic acid-based superplasticizer may be used.

1 is a view showing various application examples in which the refractory binder composition of the present invention and urushiol are stirred and applied to a lacquer module plate.

The refractory binder composition according to the present invention is mixed with urushiol to apply lacquer to the module plate.

When the mixture of urushiol and the refractory binder composition is applied, it may be coated by monochromatic printing and multicolor printing using a silk screen as shown in [Table 1].

In addition, various coating conditions, such as curing method and curing temperature, have been described as examples in [Table 1].

Coating method 1 Monochrome printing using silkscreen Coating method 2 Multicolor printing using silkscreen Curing method Bake drying using hot air or IR Curing temperature PMT 190~210℃ Curing time 1 minute 20 seconds-2 minutes 10 seconds Coated board carpenter 200目 Coating thickness Dry film thickness 5~7㎛ BASE TYPE HI POLYMER POLYESTER Coating speed 4sec based on large size 1000×2000mm Solid content (wt) 60~65% (150℃×20min) Viscosity Design 2000~3000cp (25℃) Polish 60° Gloss meter Gloss: over 95%, matte 10-15% Mouth degree 5㎛ or less

2 and 3 are views showing the results of a fireproof/flame retardant application experiment after a certain period of time after applying the mixture between urushiol and the refractory binder composition according to the present invention to a module plate.

In FIG. 2, the mixture was applied to the lower side, and it can be seen that the lower side has excellent fireproof/flame retardant performance compared to the upper side.

As described above, the present invention has been described with reference to one embodiment shown in the drawings, but this is only exemplary, and those of ordinary skill in the art can recognize that various modifications and other equivalent embodiments are possible. I will understand.

Accordingly, the true technical scope of the present invention should be determined by the technical spirit of the appended claims.
