Description

TECHNICAL FIELD [0001] The present invention relates to a composition for architectural finishing including a non-metallic mineral and a composition for coloring, and a construction finish material containing the same. [0002]

Nonmetallic minerals and a coloring composition, and a building finish material comprising the same. More specifically, it is possible to apply artificial stone colored on an inner wall, an outer wall or a floor of a building by using a composition for building finishing including a nonmetallic mineral and a mixing composition for coloring, It is strongly attached to the floor and has high durability. In addition, it has a merit of being able to finish the colored outer wall layer on the outer wall, inner wall or bottom floor of the building by a simple process such as spraying.

Natural stone, which is generally used in buildings, is widely used as a building material due to its own pattern, texture and characteristics of stone itself (durability, chemical resistance, corrosion resistance, high strength, etc.) There is a problem that the natural stone which can be used is limited because the physical properties of the stone or the pattern of the stone are not constant.

As a result, studies have been carried out to replace natural stone in various ways as artificial stone or film attached to stone to make shapes similar to those of natural stone, such as color and pattern, and as a processed product of other stone, And the like, which have a shape similar to that of natural stone, have been developed and are being advanced for various purposes.

There is a problem in that when the natural stones having a large size or the artificial stone itself are directly colored, the expression of the texture and the formation of the colored layer are not natural. Therefore, in general, a non-metallic mineral of a predetermined size is colored to form a colored layer, and a non-metallic mineral having a predetermined size formed with the colored layer is processed to produce a synthetic stone that can be used as an interior while expressing a certain pattern or texture The method is utilized.

In particular, when coloring directly on an outer wall, an inner wall or a floor of a building, it is difficult to construct the colored layer uniformly, and the durability is weak and it is difficult to express a natural texture or pattern.

Therefore, a method of constructing artificial stone made by a method of coloring or firing a small stone of a predetermined size to color the small stone and compression molding a colored small stone is applied to the outer wall, inner wall or floor of the building . In this case, since it is necessary to manufacture the artificial stone or the natural stone by using a finishing material having a predetermined size and to attach the finished material to a predetermined position of the dry material, .

In other words, even when artificial stone is used, it is necessary to apply stone to the building by machining the stone so as to fit the same structure as the natural stone. Recently, the shape of the building has been diversified and labor costs have increased, ought.

Therefore, the finishing material which finishes the outer wall, the inner wall or the floor of the building is realized with a certain composition and is injected directly at the work site, so that the finishing material of the building can be attached to the building and the structure, while the durability as well as the texture and color of the stone can be realized naturally It is necessary to plan.

Prior Art 1 (KR 10-0342176 B1) discloses a composition prepared by adding a curing agent to a resin mixture obtained by mixing a resin film composition with an epoxy resin composition, and by using the composition, And the coating surface is peeled off or worn by the external stimuli. In addition, when the coating surface is exposed to ultraviolet rays for a long period of time, there is a phenomenon of discoloration of the artificial marble, There is a drawback that the color of the coating is lost. In particular, there remains a problem that the process can not be simplified as pointed out in the present invention.

In the prior art 2 (KR 10-0366568 B1), a mixture obtained by mixing an epoxy resin composition with a synthetic resin film color chip in a resin composition at 30 to 100 캜 is stirred under reduced pressure to remove bubbles and moisture, A first curing step in which a curing agent is added to the resin mixture and the mixture is vacuum degassed again and then the mixture is poured into a mold to cause the molded molding agent to be in a touched state; So as to allow complete curing of the molded body.

However, the artificial marble produced by the above-described production method satisfies the strength required for interior and exterior materials and has excellent properties in terms of abrasion resistance, shrink resistance, water resistance, cold resistance and chemical resistance, It is disadvantageous in that the original color is lost due to the phenomenon of discoloration. Furthermore, this process also has a problem in that it can not be utilized as a composition for simplifying the process of closing the inner wall, outer wall or floor of a building recognized by the present invention.

Hereinafter, the present invention will be described in more detail.

The composition for architectural finishing including the nonmetallic mineral and the coloring composition according to an embodiment of the present invention may be selected from the group consisting of talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, , A colorant, a curing agent selected from the group consisting of methylene diphenyl diisocyanate, polymethylene polyphenyl isocyanate, and mixtures thereof, and a curing agent selected from the group consisting of polyoxyalkylene polyol 30 to 700 parts by weight of a polyoxyalkylene polyol and at least one member selected from the group consisting of toluene, methyl ethyl ketone, xylene, cyclohexanone, polyethylene glycol, methyl isobutyl ketone ( methyl isobutylketone), and mixtures thereof, and 10 to 700 parts by weight of any one selected from the group consisting of A first coloring mixture and a thickener, decanoic acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, A surface stabilizer selected from the group consisting of mineral oil, oxystearine, dimethyl polysiloxane, silicon dioxide, sorbitan monostearate, and mixtures thereof; And 10 to 300 parts by weight of propanediol relative to 100 parts by weight of the surface stabilizer.

The above-mentioned talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum, diamond, and mixtures thereof are colored non-metallic minerals that have natural color and texture.

Preferably the non-metallic mineral refers to mica. In the case of using mica, the colored layer can be formed naturally according to the first colored mixture and the second colored mixture, and when applied with a finishing material, a colored layer having excellent durability and adhesiveness can be formed.

More preferably, the non-metallic mineral may have an average diameter of 0.1 to 10 mm. According to the above range, the colored mica does not stick to each other and a natural coloring layer can be produced, and the problem that the colored layer is peeled off or the mica falls off when used as a finishing material can be prevented.

Most preferably, the non-metallic mineral comprises 100 parts by weight of mica having an average diameter of 0.5 to 2 mm, 100 to 500 parts by weight of mica having an average diameter of 1 to 3 mm with respect to the mica having an average diameter of 0.5 to 2 mm, And 100 to 500 parts by weight of mica having a diameter of 8 mm. According to the above-mentioned range, it is possible to provide a texture and color reproduction similar to a natural stone, and also to solve the problem that a portion which is stuck to the mica and is not colored occurs.

Wherein the first colored mixture is selected from the group consisting of methylene diphenyl diisocyanate, polymethylene polyphenyl isocyanate, and mixtures thereof, and a curing agent selected from the group consisting of polyoxy And 30 to 700 parts by weight of a polyoxyalkylene polyol.

The polyoxyalkylene polyol may be contained in an amount of 50 to 310 parts by weight based on 100 parts by weight of the curing agent. According to the above range, it is possible to form a coloring layer which is strong in durability and excellent in color sustainability while utilizing the color of the coloring agent.

More preferably, the polyoxyalkylene polyol may be contained in an amount of 80 to 240 parts by weight based on 100 parts by weight of the curing agent. In this range, the color sustainability of the colored layer, the durability of the colored layer, and the adhesion to non-metallic minerals can be drastically enhanced, as well as excellent color reproducibility with the use of a coloring agent.

In particular, when methylene diphenyl diisocyanate is used, adhesion and durability to irregular silica sand are excellent and color rendering can be facilitated. The curing agent is for forming a cured colored layer in a colored nonmetallic mineral and is combined with the polyoxyalkylene polyol to form a colored layer having excellent durability.

On the other hand, the use of the polyoxycalylene polyol may be excellent in curability and the color sustainability and color reproducibility may be enhanced.

The curing agent may be a mixture of methylene diphenyl diisocyanate and polymethylene polyphenyl isocyanate, preferably in a weight ratio of 1: 1 to 1:10.

More preferably from 35: 100 to 45: 100 by weight. According to the above range, the coloring layer has excellent durability, and the effect of preventing the discoloration of the coloring agent can be remarkably excellent.

The viscosity of the first colored mixture and the second colored mixture may be 0.9 to 1.2 cP. When the viscosity is less than 0.9 cP, not only the colored layer is too thin in the nonmetallic mineral such as mica but also the effect of reinforcing the mechanical strength of the mica is lowered and there is a problem of color discoloration after coloring. If the viscosity exceeds 1.2 cP, the first or second colored mixture may not be mixed well, and the colored layer may not be uniformly dispersed in the non-metallic mineral such as mica, have.

When an epoxy resin, an acrylic resin or a urethane resin is used as the curing agent, it is difficult to overcome the problem that the durability of the colored layer is lowered, and in particular, the problem of discoloration in the formed colored layer can not be solved. However, according to the composition and content and viscosity range of the composition for non-metallic mineral coloring, the coloring layer formed has high durability and coloring layer is not discolored, so that coloring and texture can be maintained for a long time.

The composition for coloring non-metallic minerals may further comprise at least one selected from the group consisting of toluene, methyl ethyl ketone, xylene, cyclohexanone, polyethylene glycol, methyl Methyl isobutyl ketone, and a mixture thereof. In addition, it may further comprise 10 to 700 parts by weight of any one selected from the group consisting of methyl isobutyl ketone and mixtures thereof.

Methylene isobutylketone, cyclohexanone, polyethylene glycol, and methyl isobutylketone are added to 100 parts by weight of the curing agent, And a mixture thereof may be used as a solvent to be used for adjusting the viscosity of the nonmetal mineral coloring composition.

The non-metallic mineral coloring composition may further comprise a coloring agent. The colorant may be considered to include a whole range of pigments that can be used by those skilled in the art as organic pigments and inorganic pigments.

On the other hand, the above-mentioned toluene, methyl ethyl ketone, xylene, cyclohexanone, polyethylene glycol, methyl isobutylketone, and mixtures thereof Is less than 10 parts by weight based on 100 parts by weight of the curing agent, there is a problem of dispersion, and it is difficult for the top coat layer to be strongly bonded to the coloring layer and also to prevent discoloration of the coloring layer There is a problem that the effect is deteriorated. When the amount exceeds 200 parts by weight, there is a problem of a decrease in bonding force for the colored layer and a decrease in mechanical durability. In addition, there is a problem that the expression of color is changed so that it is difficult to produce a colored layer naturally.

Preferably, the solvent is contained in an amount of 30 to 110 parts by weight. According to the above-mentioned range, the upper coating layer formed can be strongly bonded to the coloring layer, and discoloration of the coloring layer can be effectively prevented.

Preferably, the solvent may be any one selected from the group consisting of toluene, methyl ethyl ketone, and mixtures thereof. Control of viscosity and high volatility increase the process efficiency not only because the top coating layer is strongly bonded to the coloring layer, but also the top coating layer preventing the coloring layer from discoloring can be formed.

The composition for architectural finishing including the non-metallic mineral and the coloring composition may be one whose viscosity has been adjusted using a thickener. That is, the viscosity of the first colored mixture and the second colored mixture is lowered to a certain degree and the viscosity of the entire composition is increased while the thickening agent is mixed.

Accordingly, the first colored mixture and the second colored mixture have a viscosity of 0.9 to 1.2 cP so that the mixing of each colored mixture can be smoothly performed, and evenly dispersed in the mica to increase the mechanical strength of the mica surface and form a colored layer . Further, when the thickener is used, the viscosity of the entire composition including mica may be increased to increase the strength of the finish material applied with the composition, and the finish material using the composition may be smoothly applied.

Preferably, the thickening agent may be selected from the group consisting of cellulose, gelatin, pectin, guar gum, xanthan gum, and mixtures thereof. If the thickening polysaccharide is used, the viscosity of the entire composition may be increased.

More preferably, the thickener is a mixture of guar gum and xanthan gum at a weight ratio of 2: 1, and may be contained in an amount of 10 to 200 parts by weight based on 100 parts by weight of the surface stabilizer. According to the above range, the first coloring mixture and the second coloring mixture contained in the composition for building finishing including the nonmetallic mineral and the coloring composition are mixed, and the first coloring mixture and the second coloring mixture are mixed in the mica The viscosity of the entire composition can be increased after being evenly dispersed on the surface, which is effective. That is, if the viscosity of the composition is rapidly increased, the colored mixture may not be mixed well and the uncoloured portion may be formed or the effect of reinforcing the mechanical strength on the mica surface may deteriorate.

Most preferably, the thickener is a mixture of guar gum and xanthan gum in a weight ratio of 4: 1 to 1: 4, and is contained in an amount of 10 to 200 parts by weight based on 100 parts by weight of the surface stabilizer, 0.01 to 0.5 parts by weight of potassium diphosphate may be included.

When the second potassium phosphate is included, the rate at which the viscosity of the composition as a whole increases with use of the thickener can be slowed, so that the colored mixture and the mica can be effectively mixed and the viscosity of the entire composition can be increased. When the second potassium phosphate is contained in an amount of less than 0.01 part by weight, there is almost no retarding effect on the thickening, and when it exceeds 0.5 part by weight, the thickening effect does not occur.

That is, the present invention has an advantage in that the process efficiency is remarkably high by mixing the blend sequentially and coloring the blend in one step by using the viscosity and finally producing the colored nonmetallic mineral.

The coloring agent may be an inorganic paint or an organic paint, and may be considered to include all kinds of paint that can be used by a person skilled in the art.

The surface stabilizer may be selected from the group consisting of decanoic acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, and may be selected from the group consisting of mineral oil, oxystearine, dimethyl polysiloxane, silicon dioxide, sorbitan monostearate, and mixtures thereof.

When the surface stabilizer is used, uncolored portions are not generated in the nonmetallic mineral including mica, and the mechanical strength of the mica according to the use of the colored mixture is uniformly increased. Thus, the mixing process of the composition and the finish material It is possible to prevent the problem of the mica being broken in the construction process, thereby improving the process efficiency.

Preferably, the surface stabilizer may include mineral oil and oxystearine in a weight ratio of 1: 3 to 3: 1. In the above range, the color tone of the color mixture due to the use of the surface stabilizer is not affected, and natural color and texture can be obtained.

And the second colored mixture comprises 10 to 300 parts by weight of propanediol per 100 parts by weight of the surface stabilizer.

When the propanediol is used, it is possible to prevent the colored mica from sticking to each other and also to produce a natural color feeling.

In particular, the composition for architectural finishing including the nonmetallic mineral and the coloring composition is not a method in which the mixture is sequentially compounded and the compounded mixture is applied to a stone or the like, unlike the prior art, but the nonmetal mineral including the stone and the whole coloring composition There is a problem that a portion which is not colored in the mica or the surface of which mechanical strength is not reinforced may occur, and the durability as a whole deteriorates. Particularly, when the second coloring mixture is not used, there is a problem that the mica is stuck between the mica, so that a natural texture is not entirely produced and a lot of uncolored portions are generated.

Wherein the non-metallic mineral and the first colored mixture are mixed in a weight ratio of 1:10 to 10: 1, and the non-metallic mineral and the second colored mixture are mixed in a ratio of 1:10 to 10: 10: 1 by weight.

According to the above range, surface strengthening of non-metallic minerals such as mica and uniform coloring layer can be formed.

When the additive represented by the general formula (2) is used, the mechanical strength of the mica is increased, the color of the colored layer is natural, and color discoloration due to ultraviolet rays of the colored layer can be prevented.

Preferably, the composition for architectural finishing including the non-metallic mineral and the coloring composition may include 50 to 400 parts by weight of an acryl emulsion based on 100 parts by weight of the curing agent. When the acrylic emulsion is used, the mechanical strength of the finish layer formed using the composition for architectural finishing including the non-metallic mineral and the coloring composition can be greatly increased. That is, the strength of the entire finish material is increased and a natural color rendering effect can be obtained.

When the acrylic emulsion is contained in an amount of less than 50 parts by weight, the effect of reinforcing mechanical strength is deteriorated. When the acrylic emulsion is contained in an amount exceeding 400 parts by weight, there is a problem that it is difficult to produce a natural color and texture of the finishing material.

More preferably, the composition for architectural finishing comprising the non-metallic mineral and the coloring composition comprises 50 to 400 parts by weight of an acryl emulsion and 0.01 to 1 part by weight of an aqueous ammonia, based on 100 parts by weight of the curing agent It may be included as part.

When the hydroxyammonium is included, the effect of increasing the mechanical strength can be maximized, so that the finishing material can be stably installed according to the use of the composition, and natural coloring can be achieved without affecting the color. When the hydroxyammonium salt is contained in an amount of less than 0.01 part by weight, there is no mechanical strength reinforcing effect. When the amount of the hydroxyammonium salt is more than 1 part by weight, the mechanical strength of the acrylic emulsion is lowered.
