Description
본 발명은 자연석 질감 및 부분 축광성을 갖는 인조대리석 및 그 제조방법에 관한 것이다. 보다 구체적으로, 본 발명은 불포화 폴리에스테르 수지, 실리카 함유 화합물 및 안료(유기안료, 무기안료 또는 이들의 혼합물)를 포함하는 비축광성 모재와 불포화 폴리에스테르 수지, 실리카 함유 화합물 및 축광안료를 포함하는 축광성 무정형 무늬 부분을 포함하여 자연석 질감 및 축광성 패턴을 형성하는 인조대리석에 관한 것이다.
TECHNICAL FIELD The present invention relates to an artificial marble having a natural stone texture and a partial accumulative property, and a method of manufacturing the same. More specifically, the present invention relates to a non-shrinkable base material comprising an unsaturated polyester resin, a silica-containing compound and a pigment (an organic pigment, an inorganic pigment or a mixture thereof), a shaft containing an unsaturated polyester resin, To an artificial marble forming a natural-stone texture and an accumulative pattern including a light-like amorphous pattern portion.
화강암(Granite)이나 대리석(Marble)과 같은 천연석은 표면의 무늬가 아름다워 예로부터 건축 장식재로 사용되어 왔으며, 최근에는 고품격 질감을 나타내는 재료로서 각광을 받아 바닥재, 벽체, 싱크대 상판 등의 분야에서 그 수요가 크게 증가되고 있다. 이로 인해 고가의 천연석만으로는 그 수요를 충족할 수 없게 되고, 이를 계기로 다양한 종류의 인조석이 개발되었다.Natural stones such as granite and marble have been used as decorative materials since ancient times because of their beautiful surface pattern. Recently, they have been spotlighted as high-quality textured materials, and their demand in the fields of flooring, walls, . As a result, expensive natural stone alone can not meet the demand, and a variety of artificial stones have been developed.
인조석은 크게 아크릴계 또는 불포화 폴리에스테르 베이스 수지에 무기 충진제, 착색제, 경화제 등 각종 혼합재료를 첨가하여 제조되는 일반 인조석과, 무기계(실리카계) 천연광물과 바인더 수지를 혼합한 컴파운드(compound)를 진공 압축 성형하여 천연석의 질감을 그대로 나타내도록 만든 수지계 강화 천연석(일명 "Engineering stone"이라고 함)으로 분류된다.Artificial stones are mainly produced by adding various synthetic materials such as inorganic fillers, coloring agents and hardeners to acrylic or unsaturated polyester base resins, and inorganic compounds (silica-based) natural minerals and binder resins, It is classified as a resin-reinforced natural stone (also called "Engineering stone") which is molded and made to express the texture of natural stone.
상기 수지계 강화 천연석은 혼합되는 천연광물의 종류, 수지 또는 안료의 색상, 교반 공정 등에 따라 다양한 색상과 질감을 나타내도록 제조될 수 있으며, 천연광물을 주원료로 하기 때문에 일반 인조석보다 훨씬 더 우수한 천연 질감을 나타내어 최근에 그 수요가 크게 증가되고 있다.The resin-reinforced natural stone can be manufactured to exhibit various colors and textures depending on the kinds of natural minerals to be mixed, the colors of resins or pigments, and the stirring process, and natural minerals are used as main raw materials, The demand has been greatly increased recently.
이와 같이 제조되는 수지계 강화 천연석은, 단색으로 제조되거나, 서로 다른 색상의 안료가 각각 첨가되어 서로 다른 색상을 갖는 수지 혼합물을 믹서에서 혼합함으로써 다색톤을 갖도록 제조되거나, 칩을 사용하여 천연석 질감을 갖도록 하고 있다.The resin-reinforced natural stone produced as described above may be prepared to have a multicolor tone by mixing monochromatic pigments or pigments of different colors and mixing different resin colors in a mixer, or by using chips to have a natural stone texture .
그러나, 위와 같은 종래 수지계 강화 천연석의 색감, 패턴, 무늬는 이미 오래전 사용되어 오던 것으로서, 천연석이 가지고 있는 다양한 질감의 연출을 요구하는 소비자의 욕구를 충족시키기에는 부족하며, 단조로운 느낌을 탈피하고 있지 못하다는 문제점이 있다.However, the color, pattern and pattern of the conventional resin-reinforced natural stone as described above have been used for a long time, and they are not sufficient to meet the desire of consumers demanding the production of various textures possessed by natural stones, There is a problem.
이러한 인조대리석의 기능 및 성능 향상을 위한 시도로서 축광재 등의 야광발광성 물질이나 자외선 흡수에 동반하여 발광하는 자외선발광재 등의 발광성 물질을 이용하여 인조대리석에 발광 기능을 부여하는 시도가 계속되어 왔다.As an attempt to improve the function and performance of such artificial marble, attempts have been made to impart a luminescent function to artificial marble by using a luminescent material such as a luminous luminescent material such as a phosphorescent material or an ultraviolet luminescent material that emits light accompanying ultraviolet absorption .
그러나 기존의 축광성 인조대리석은 표면에 축광안료를 코팅하거나 축광성 칩(Chip)을 활용하여 질감을 창출하는 방식이었다. 축광성 칩을 사용할 경우 균일한 축광성을 나타낼 수 없고, 표면에 축광안료를 코팅한 경우는 사람 이동이 많은 바닥이나 표면 경도로 인하여 오랜 시간을 사용 못하는 문제점이 있었다.Conventional artificial marble, however, was a method of coating the surface with a phosphorescent pigment or using a condensing chip to create texture. When a photoconductive chip is used, it can not exhibit uniform photoconductivity. When a phosphorescent pigment is coated on the surface, there is a problem in that it can not be used for a long time due to a surface having a lot of human movement or surface hardness.
또한, 종래의 축광성 인조대리석은 충분한 축광성능 달성을 위하여 축광안료를 과량 사용하였다. 그러나 축광안료는 고가의 물질로서 이를 과량 사용하게 되면 제조원가의 증대로 상용화에 큰 걸림돌이 될 수 밖에 없다. 따라서 축광안료의 사용을 최소화하면서 충분한 축광성을 달성하는 것이 요구되어 왔다.Conventional artificial marble has also used excessive amounts of phosphorescent pigments to achieve sufficient luminous performance. However, phosphorescent pigments are expensive materials, and if they are used excessively, they will be a big obstacle to commercialization due to an increase in manufacturing cost. Therefore, there has been a demand for achieving sufficient accumulative properties while minimizing the use of phosphorescent pigments.
따라서 본 발명자들은 이러한 문제점을 인지하여 적절한 배합비율을 연구하였으며, 그 결과 축광안료의 함량을 최소화하면서 장시간 동안 충분한 휘도로 지속되는 축광성을 달성하고, 자연석에 가까운 인조대리석의 질감을 유지하는 인조대리석을 개발하기에 이른 것이다.
Therefore, the inventors of the present invention have studied an appropriate blend ratio and have found that the blend of the artificial marble, which maintains the texture of the artificial marble close to the natural stone, To develop.

본 발명의 다른 목적은 자연석 질감을 가지면서 부분적인 축광패턴을 갖는 인조대리석을 제공하는 것이다.Another object of the present invention is to provide an artificial marble having a natural stone texture and a partial luminous pattern.

이하에서는 본 발명의 인조대리석을 구성하는 각 구성성분에 대하여 구체적으로 살펴보기로 한다.Hereinafter, each component constituting the artificial marble of the present invention will be specifically described.
(A) 불포화 폴리에스테르 수지(A) an unsaturated polyester resin
본 발명에서 수지 성분은 인조대리석의 골격을 형성하는 성분인 천연석 입자 및 무기질 충전재를 감싸고, 가교제와 함께 전체를 결합하는 역할을 하며, 인조대리석이 형성되었을 때 탄성 혹은 인장강도를 부여하는 기능을 한다. In the present invention, the resin component encapsulates the natural stone particles and the inorganic filler, which form the skeleton of the artificial marble, binds the whole together with the crosslinking agent, and functions to impart elasticity or tensile strength when artificial marble is formed .
본 발명은, 상기 수지 성분으로 천연석 입자 등과 결합력이 우수한 불포화 폴리에스테르 수지(UPE resin; Unsaturated PolyEster resin)를 사용하는 것을 특징으로 한다.The present invention is characterized by using UPE resin (Unsaturated Polyester resin) having excellent bonding strength with natural stone particles or the like as the resin component.
본 발명에서 사용되는 불포화 폴리에스테르 수지는 당업계에 통상적으로 공지되어 있으며, 다가산과 다가알콜의 에스테르화 반응 생성물로서 상기 다가산 및/또는 다가알콜 화합물은 불포화 부분을 포함한다.The unsaturated polyester resin used in the present invention is conventionally known in the art, and the polyvalent acid and / or polyhydric alcohol compound as an esterification reaction product of a polyvalent acid and a polyvalent alcohol includes an unsaturated portion.
상기 다가산으로는 폴리카르복실산, 폴리카르복실산 무수물, 폴리카르복실산 할라이드, 폴리카르복실산 에스테르를 사용할 수 있으며, 불포화 폴리카르복실산의 구체적인 예로는 말레익산, 무수말레산, 푸마르산, 클로로말레익산, 에틸말레익산, 이타코닉산, 시트라코닉산, 제로닉산, 리로친코닉산, 메사코닉산, 아코닉산, 에시틸렌 다카르복실산 또는 이들의 혼합물 등을 사용할 수 있다. 또한, 폴리에스테르 수지의 제조에 통상적으로 사용되는 프탈산, 이소프탈산, 테레프탈산, 숙신산 또는 이들의 혼합물을 사용할 수 있다.Examples of the polyvalent acid include polycarboxylic acids, polycarboxylic acid anhydrides, polycarboxylic acid halides and polycarboxylic acid esters. Specific examples of the unsaturated polycarboxylic acids include maleic acid, maleic anhydride, fumaric acid, There may be used chloromaleic acid, ethyl maleic acid, itaconic acid, citraconic acid, geronic acid, lyroconic acid, mesaconic acid, aconic acid, ethylenetradecarboxylic acid or mixtures thereof. Further, phthalic acid, isophthalic acid, terephthalic acid, succinic acid, or a mixture thereof, which are conventionally used in the production of a polyester resin, may be used.
상기 다가 알콜로는 에틸렌글리콜, 디에틸렌글리콜, 프로필렌글리콜, 디프로필렌글리콜, 1,3-부탄디올, 1,6-헥산디올, 네오펜틸글리콜, 1,4-시클로헥산디올 등의 2가 알콜, 글리세린 등의 3가 알콜, 펜타에리쓰리톨 등의 4가 알콜 등 또는 이들의 혼합물을 사용할 수 있다. 또한, 불포화 다가 알콜의 구체적인 예로는 부텐디올, 펜텐디올, 알릴 또는 비닐 글리세롤 에테르, 알릴 또는 비닐 펜타에리쓰리톨, 또는 이들의 혼합물을 사용할 수 있다. Examples of the polyhydric alcohol include dihydric alcohols such as ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, 1,3-butanediol, 1,6-hexanediol, neopentyl glycol and 1,4- , Trihydric alcohols such as pentaerythritol, and the like, or mixtures thereof. Specific examples of the unsaturated polyhydric alcohols include butenediol, pentenediol, allyl or vinyl glycerol ether, allyl or vinylpentaerythritol, or a mixture thereof.
상기 불포화 폴리에스테르 수지는 그 분자량이 70,000 ~ 100,000인 것을 사용하는 것이 바람직하다. 불포화 폴리에스테르 수지의 분자량이 클수록 천연석 입자와의 결합력이 우수하여 연마 공정에서 수지의 일부분이 깎여 나가더라도 외부로 드러난 천연석 입자를 효과적으로 고정시켜 줄 수 있기 때문이다. 불포화 폴리에스테르 수지의 분자량이 70,000 미만이면 인조대리석의 표면에서 천연석 입자의 탈락현상이 발생할 수 있고, 100,000을 초과하면 점성이 너무 커서 천연석 입자와 잘 혼합되지 않는 단점이 있다.The unsaturated polyester resin preferably has a molecular weight of 70,000 to 100,000. The larger the molecular weight of the unsaturated polyester resin is, the better the binding force with the natural stone particles is, and even if a part of the resin is shaved in the polishing process, the natural stone particles exposed to the outside can be effectively fixed. If the molecular weight of the unsaturated polyester resin is less than 70,000, the natural stone particles may fall off from the surface of the artificial marble. If the molecular weight exceeds 100,000, the viscosity of the natural stone particles is too large to mix well with the natural stone particles.
본 발명에서 상기 불포화 폴리에스테르 수지(A)는 비축광성 모재(I)에 있어서, 불포화 폴리에스테르 수지(A) 및 실리카 함유 화합물(B)을 포함하는 비축광성 모재(I) 조성물 100 중량%에 대하여 7 ~ 10 중량%로 포함될 수 있으며, 축광성 무정형 무늬 부분(II)에 있어서, 불포화 폴리에스테르 수지(A), 실리카 함유 화합물(B) 및 축광안료(C)를 포함하는 축광성 무정형 무늬 부분(II) 조성물 100 중량%에 대하여 7 ~ 10 중량%로 포함될 수 있다. 만약, 불포화 폴리에스테르 수지를 7 중량% 미만으로 포함시 천연석 입자와의 결합력이 저하될 수 있으며, 10 중량%를 초과하는 경우에는 천연석의 외관 및 질감을 상실될 수 있기 때문이다.In the present invention, the unsaturated polyester resin (A) is a mixture of 100 wt% of the non-shrinkable base material (I) composition comprising the unsaturated polyester resin (A) and the silica-containing compound (B) (A), the silica-containing compound (B) and the phosphorescent pigment (C) in the photoconductive amorphous pattern portion (II) II) composition in an amount of 7 to 10% by weight based on 100% by weight of the composition. If the unsaturated polyester resin is contained in an amount of less than 7% by weight, the bonding strength with the natural stone particles may be deteriorated. If it exceeds 10% by weight, the appearance and texture of the natural stone may be lost.
(B) 실리카 함유 화합물(B) a silica-containing compound
본 발명의 실리카 함유 화합물(B)은 비축광성 모재(I)에 있어서, 불포화 폴리에스테르 수지(A) 및 실리카 함유 화합물(B)을 포함하는 비축광성 모재(I) 조성물 100 중량%에 대하여 90 ~ 93 중량%로 포함될 수 있으며, 축광성 무정형 무늬 부분(II)에 있어서, 불포화 폴리에스테르 수지(A), 실리카 함유 화합물(B) 및 축광안료(C)를 포함하는 축광성 무정형 무늬 부분(II) 조성물 100 중량%에 대하여 85 ~ 91 중량%로 포함될 수 있다. 상기 범위와 같이 실리카 함유 화합물을 고함량으로 포함함으로써 자연석에 가까운 외관 및 질감을 형성할 수 있기 때문이다.The silica-containing compound (B) of the present invention is a non-shrinkable base material (I), which contains 90 to 90% by weight of a non-shrinkable base material (I) composition containing the unsaturated polyester resin (A) (II) containing an unsaturated polyester resin (A), a silica-containing compound (B) and a phosphorescent pigment (C) in the photothermographic amorphous pattern portion (II) And 85 to 91% by weight based on 100% by weight of the composition. This is because the silica-containing compound is contained in a high content as in the above range, so that the appearance and texture close to the natural stone can be formed.
또한, 본 발명의 실리카 함유 화합물(B)은 실리카 함유 화합물(B) 100 중량%에 대하여 천연석 입자(B1) 50 ~ 80 중량% 및 무기질 충전재(B2) 20 ~ 50 중량%를 포함할 수 있다. The silica-containing compound (B) of the present invention may contain 50 to 80% by weight of the natural stone particles (B1) and 20 to 50% by weight of the inorganic filler (B2) based on 100% by weight of the silica-containing compound (B).
(B1) 천연석 입자(B1) Natural stone particles
본 발명의 인조대리석이 천연석에 가까운 외관 및 질감을 형성하기 위하여 천연석 입자를 필수적으로 포함한다. The artificial marble of the present invention essentially contains natural stone particles to form a natural stone-like appearance and texture.
상기 천연석 입자는 자연에서 얻어지는 다양한 종류의 무기계 골재를 사용할 수 있으나, 축광 효과를 증대시키기 위하여 투명성을 가지는 천연석 입자를 사용하는 것이 바람직하다. 투명성을 가지는 천연석 입자를 사용하는 이유는 인조대리석 내부에서 분산이나 난반사를 촉진시키고 이로 인하여 축광안료의 대부분이 빛에너지를 흡수할 수 있게 도와주기 때문이다. The natural stone particles may use various kinds of natural aggregates obtained from nature, but it is preferable to use natural stone particles having transparency in order to increase the luminous effect. The reason why the natural stone particles having transparency is used is that it facilitates the dispersion or diffuse reflection in the artificial marble, thereby allowing most of the phosphorescent pigment to absorb the light energy.
상기 투명성을 가지는 천연석 입자로는 실리카 샌드, 석영칩, 수정 또는 이들의 혼합물로 이루어진 천연석 입자를 사용할 수 있다.As the natural stone particles having transparency, natural stone particles made of silica sand, quartz chips, quartz, or a mixture thereof can be used.

As the natural stone particles, various sizes of minerals can be used, but it is preferable to use particles having an average particle size of 0.1 to 9.0 mm. In the case of using the natural stone particles having an average particle size of less than 0.1 mm in the blend of the present invention, the time to reach the luminance of 3 mcd / m 2 is only 0.6 hours.
특히, 본 발명에서 상기 천연석 입자는, 평균입경이 상이한 실리카 샌드(b1) 및 석영칩(b2)을 혼합하여 사용하는 것이 바람직하며, 실리카 샌드의 평균입경은 0.1 ~ 1.2mm, 석영칩의 평균입경은 1.2 ~ 9.0mm인 것이 더욱 바람직하다.
