Description
본 발명은 인조석 및 그 제조 방법에 관한 것으로, 상세하게는 제조 공정시 가스 발생이 없고 별도의 양생과정이 불필요한 인조석 및 그 제조 방법에 관한 것이다.The present invention relates to an artificial stone and a method for manufacturing the same, and more particularly, to an artificial stone and a method for manufacturing the same, which does not generate gas during the manufacturing process and does not require a separate curing process.
건물의 내외장재 및 구조물에 쓰이는 석재로서, 자연석을 채취, 가공하여 이용할 수 있는데, 이 경우 채취하는 과정에서 발생되는 환경파괴, 오염과 채취 후 가공단계의 어려움으로 제조 비용이 많이 들게 된다.As a stone used for interior and exterior materials and structures of buildings, natural stone can be collected and processed. In this case, manufacturing costs are high due to environmental destruction, contamination, and difficulty in processing after collection.
따라서, 자연석을 대신하여 인조석을 이용하는데, 일반적으로 인조석이란 시멘트에 물, 세골재 및 종석들을 적당량씩 혼합하여 경화시킨 후 그 표면부를 연마하여 제조되는 시멘트 제품의 일종이다.Therefore, artificial stone is used instead of natural stone. Generally, artificial stone is a kind of cement product manufactured by mixing water, fine aggregate, and feldspar in cement in an appropriate amount to harden and then polishing the surface thereof.
종래에 인조석을 제조하는 방법으로 불포화 폴리에스테르계의 수지에 안료를 혼합하여 경화시키는 방법과 열경화성 폴리에스테르 수지를 유리섬유에 함침시켜 경화시키는 FRP(Fiberglass Reinforced Plastic)의 제조방법이 있었다.Conventionally, there has been a method of preparing artificial stone by mixing a pigment in an unsaturated polyester-based resin and curing, and a method of manufacturing FRP (Fiberglass Reinforced Plastic) in which a thermosetting polyester resin is impregnated with glass fiber and cured.
또한 인조석의 기능, 성능향상의 하나의 시도로서, 축광재 등의 야광성 물질이나 발광성 물질을 이용해서 광기능을 부여하는 것이 제안되었다. 이는 인조석의 바인더로서의 수지성분에 인광물질을 혼합해서 고화시키는 것 또는 불포화폴리에스테르, 메타크릴수지, 유리 등에 알루민산 스트론튬 등의 축광성 형광물질이나 자외선형광성물질을 혼합해서 고화시키고, 이것을 분쇄한 것을 골재로서 이용해서 인조석을 구성하는 것이다.Further, as an attempt to improve the function and performance of artificial stone, it has been proposed to impart an optical function using a luminous material such as a phosphorescent material or a luminescent material. This is obtained by mixing and solidifying a phosphor with a resin component as an artificial stone binder, or by solidifying by mixing a phosphorescent fluorescent substance such as strontium aluminate or an ultraviolet fluorescent substance with unsaturated polyester, methacryl resin, glass, etc., and pulverizing it. It is used as aggregate to form artificial stone.
그러나 상기와 같은 공지기술에 따라 수지, 안료, 또는 축광성 물질을 이용하여 인조석을 제조하는 경우, 제조과정이 성형체의 형성후 열을 가하고, 다시 연마하는 과정을 거치며, 반드시 양생과정을 거쳐야 하므로 제조과정이 복잡하고, 설비비가 많이 발생하며, 특히 제조된 인조석의 중량이 크다는 문제점이 있었다.However, when the artificial stone is manufactured using a resin, a pigment, or a photoluminescent material according to the above-mentioned known technology, the manufacturing process is performed after applying a heat after the formation of the molded body, and then again polishing, and must be cured. The process is complicated, a lot of equipment costs are generated, in particular, there was a problem that the weight of the manufactured artificial stone is large.
또한 상기 축광성 물질이 혼입되는 경우에도 적정성분을 적정량 혼입하지 못하여 축광 기능의 향상이 없었던 문제점이 있었다.In addition, even when the photoluminescent material is mixed, there is a problem in that there is no improvement in the photoluminescence function due to the inadequate mixing of an appropriate amount.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로,The present invention has been made to solve the above problems,
본 발명의 목적은 수지를 이용하면서도, 방수성, 내화성, 내약품성을 개선하며 제조원가를 절감하고, 강도를 증진시키며, 외관이 유려하고, 경량인 인조석을 제공하는 한편, 특히 양생과정이 불필요하여 제조과정이 간편하고 설비비가 절감되는 인조석 및 그 제조방법을 제공하는 것이다.The purpose of the present invention is to improve the waterproof, fire resistance, chemical resistance, while reducing the cost of production, increase the strength, improve the appearance, provide a lightweight and artificial stone, and in particular, no curing process is required, while using a resin It is to provide a simple and cost-effective artificial stone and its manufacturing method.

이하 본 발명에 따른 인조석 및 그 제조방법에 대하여 상세하게 설명한다.Hereinafter, the artificial stone according to the present invention and a manufacturing method thereof will be described in detail.
본 발명에서는 석고분말 90~94중량부에 대해 불포화 폴리에스테르 수지 또는 우레탄 6~10중량부를 포함하는 혼합물을 조성한 후, 상기 혼합물 100중량부에 대하여 경화제 1~5중량부, 난연제 3~10중량부, 혼화제 3~10중량부를 혼화하여 미경화 인조석을 제조한다.In the present invention, after forming a mixture comprising 6 to 10 parts by weight of unsaturated polyester resin or urethane based on 90 to 94 parts by weight of gypsum powder, 1 to 5 parts by weight of a curing agent and 3 to 10 parts by weight of a flame retardant , By mixing 3 to 10 parts by weight of admixtures to prepare an uncured artificial stone.
상기 불포화폴리에스테르 수지 또는 우레탄이 6중량부 미만으로 사용되는 경우 첨가효과가 없고, 10중량부를 초과하는 경우 인조석의 강도를 떨어뜨리게 되고, 온도, 압력등의 제조공정조건을 제어하기가 용이하지 않다.When the unsaturated polyester resin or urethane is used in less than 6 parts by weight, there is no additive effect, when the unsaturated polyester resin is more than 10 parts by weight, the strength of the artificial stone is reduced, it is not easy to control the manufacturing process conditions such as temperature, pressure .
바람직하게는 상기 미경화 인조석은 상기 혼합물 100중량부에 대하여 축광안료로서 입도 15, 비중 4.1인 ZnS-Cu를 5중량부 포함한다. 상기 축광안료는 초휘광도는 높고 잔광시간이 특히 길다.Preferably, the uncured artificial stone contains 5 parts by weight of ZnS-Cu having a particle size of 15 and a specific gravity of 4.1 as a phosphorescent pigment based on 100 parts by weight of the mixture. The photoluminescent pigment has a high luminance and a long afterglow time.
또한 상기 미경화 인조석은 상기 혼합물 100중량부에 대하여, 음이온 방출 및 원적외선 방출을 위한 세라믹 재료 예를 들어, 산화알루미늄, 이산화규소등을 5중량부 포함하는 것이 더욱 바람직하다.In addition, the uncured artificial stone more preferably contains 5 parts by weight of a ceramic material, for example, aluminum oxide, silicon dioxide, and the like for anion emission and far infrared ray emission, based on 100 parts by weight of the mixture.
상기 혼합물 100중량부에 대하여, 석고분말외에 추가적으로 종석 예를 들어 한수석, 화강석, 안산암, 대리석등의 종석과 세골제를 포함할 수 있으며, 종석과 세골재의 혼합물 10 중량부 포함하는 것이 바람직하다.With respect to 100 parts by weight of the mixture, in addition to the gypsum powder, it may additionally include feldspar, such as hanseok, granite, andesite, marble, and fine bone, and preferably contains 10 parts by weight of a mixture of feldspar and fine aggregate.
경화제는 예를 들어 유기과산화물과 같이 사용하는 3급 아민등을 사용하며, 경화제가 1중량부 미만으로 포함되는 경우 첨가효과가 없고, 5중량부를 초과하는 경우 제조하기가 어려워 진다. 경화제는 동절기, 하절기에 따라 사용량을 조절할 수 있으며, 동절기일수록 상기 범위내에서 다량으로 사용한다.The curing agent is used, for example, tertiary amines used together with organic peroxides, and when the curing agent is contained in less than 1 part by weight, there is no additive effect, and when it exceeds 5 parts by weight, it becomes difficult to manufacture. The amount of the curing agent can be adjusted according to the winter season, summer season, the winter season is used in a large amount within the above range.
난연제는 공지된 난연제를 사용하며, 난연제가 3중량부 미만으로 포함되는 경우 첨가효과가 없고, 10중량부를 초과하여 사용하는 경우는 제조과정에서 상기중량부를 가지는 수지의 사용에 따라 난연효과를 부여하기 위한 대응양을 초과하는 것으로 제조원가가 상승된다.The flame retardant uses a known flame retardant, and if the flame retardant is included in less than 3 parts by weight, there is no additive effect, when using more than 10 parts by weight to give a flame retardant effect according to the use of the resin having the above weight parts in the manufacturing process The manufacturing cost increases by exceeding the corresponding amount.
혼화제는 탄산칼슘, 시안화칼슘 및 초산칼슘으로 이루어지 그룹에서 선택되는 적어도 하나 이상을 포함하며, 이를 물에 섞어 비중이 1.3 내지 1.4정도가 되도록 한 것으로, 인조석의 두께에 따라 소정량의 물을 더 섞어 희석하여 사용한다. 이러한 혼화제는 조직의 치밀성을 높여 방수기능 및 압축강도를 상승시키게 된다.The admixture comprises at least one selected from the group consisting of calcium carbonate, calcium cyanide and calcium acetate, which is mixed with water so as to have a specific gravity of about 1.3 to 1.4, and a predetermined amount of water is further added depending on the thickness of the artificial stone. Mix and dilute to use. These admixtures increase the compactness of the tissue to increase the waterproof function and compressive strength.
석고분말을 포함하기 때문에 경량의 인조석을 제조할 수 있고, 동시에 상기 혼화제의 사용으로 인조석에 요구되는 강도조건 및 방수조건을 충족할 수 있다. 그리고 석고분말을 사용하면서도 소정의 축광안료를 사용하여 외관을 유려하게 할 수 있다. 또한 불포화 폴리에스테르 수지 또는 우레탄을 사용함에 따라 인조석 제조공정중 가스 발생이 없어 인조석에 있어서 방수성 및 내약품성이 저하되는 문제점이 해결된다.Since it contains gypsum powder, it is possible to manufacture a lightweight artificial stone, and at the same time, the use of the admixture can meet the strength and waterproof conditions required for artificial stone. And while using gypsum powder, it is possible to smooth the appearance by using a predetermined photoluminescent pigment. In addition, there is no gas generated during the artificial stone manufacturing process by using an unsaturated polyester resin or urethane, thereby solving the problem of deterioration in waterproofing and chemical resistance in artificial stone.
