Description
본 발명은 인조석 판재에 관한 것으로, 특히 폐된 백운석 및 화강석을 활용한 건축용 인조석 판재 제조에 관한 것이다.The present invention relates to artificial stone plate, and in particular to the manufacture of artificial stone plate for building utilizing the waste dolomite and granite.
국내 각 석재 채석장에서부터 원석을 채굴하여 건축용 석판재로 가공되기까지 각 가공공정에서 석재의 손실율은 60%를 상회하고 있으며 이들 폐기되고 있는 손실물중 극히 일부만이 도로 포장용 골재로 활용되고 있으며, 그밖에 대부분은 폐기, 방치되어 공해를 유발하고 있다.In each processing process, the loss rate of the stone exceeds 60% from domestic stone quarry to raw stone mining and processing into building slabs. Only a few of these wastes are used for road pavement aggregate. Is disposed of and left unattended, causing pollution.
따라서 본 발명은 석재 가공공정에서 발생되는 폐기물을 활용하여 인조석 판재를 제조하여 건축재로 사용하므로 폐자원의 활용 극대화 및 공해유발 물질의 최소화를 도모한 기술이다.Therefore, the present invention is a technology that aims to maximize the utilization of waste resources and minimize the pollution-causing materials by manufacturing artificial stone plate using the waste generated in the stone processing process as a building material.
일반적으로 인조석 판재의 제조방법으로는 규사본, 장석분, 석분에 붕사, 소다회, 규불화 소다 등 용융조제와 규산소다를 첨가 혼합하여 이를 주형에 투입하여, 일정한 두께로 압착 성형한 이후 이 성형물을 건조시켜 800℃ 이상에서 40-60분간 소성하여 제조하는 방법과 석분과 수지를 혼합하여 일정 두께로 목형틀에 1-2일간 방치하여 경화시켜 제조하는 방법이 있다.In general, as a method of manufacturing artificial stone plate, a molten aid such as borax, soda ash, and sodium fluoride is added and mixed with silica sand, feldspar powder, and stone powder, and added to a mold, which is then pressed into a mold and press-molded to a predetermined thickness. There is a method of manufacturing by drying and baking for 40-60 minutes at 800 ℃ or more and a method of manufacturing by mixing with stone powder and resin, and left to cure in a wooden frame 1-2 days to a certain thickness.
그러나 상기 방법중 전자는 고온에서 소성하여 제조하므로 많은 에너지가 소모되어 제조원가 상승을 초래하고 폐기물인 석분의 사용율은 20% 미만으로 폐자원의 활용율이 저조하다.However, since the former is manufactured by firing at a high temperature, a lot of energy is consumed, which leads to an increase in manufacturing cost, and the utilization rate of waste powder is less than 20%, and the utilization rate of waste resources is low.
또한 후자는 폐기물인 석분의 사용율은 70-75%로 폐자원의 활용율은 전자보다 높은 반면 이때 사용되는 비교적 고가인 수지의 소요량이 25-30%로 제조원가 상승요인과 수지와 석분을 혼합할 때 공기가 스며들어가 제조한 인조석 판재에 미세한 기공이 생성되어 물의 흡수율이 높고 압축강도가 떨어지며 제품의 경화시간이 장시간 소요되어 생산성이 낮아지는 결점이 있다.In addition, the latter uses 70-75% of waste dust, which is higher than the former, while the use of relatively expensive resin is 25-30%. Fine pores are generated in the artificial stone plate that is impregnated, resulting in high water absorption rate, low compressive strength, long curing time, and low productivity.
그리고 이미 특허공개 92-6249호가 알려져 있으나 본 발명에서는 폐기된 백운석 및 화강석 폐석을 활용하여 인조석 판재를 제조한 것으로 표면이 현재 건축재용 내·외장재로 사용되는 백운석, 화강석, 천연 석판재와 흡사한 고유의 문양과 질감을 나타낼 수 있는 것을 특징으로 하고 있으나 상기 기공개된 기술은 단지 규석을 주성분으로 한 폐광미를 사용하므로 표면이 본 발명에서 제조한 인조석 판재처럼 천연석 판재 고유의 문양과 질감을 나타낼 수 없다.And yet, Patent Publication No. 92-6249 is known, but in the present invention manufactured artificial stone plate by using the dolomite and granite waste stone discarded, the surface is similar to the dolomite, granite, natural slab that is currently used as interior and exterior materials for building materials It is characterized in that it can represent the pattern and texture of the above-described technology, but the ground-breaking technology using only the quartz tailings as a main component, the surface can exhibit the unique pattern and texture of natural stone plate like the artificial stone plate manufactured in the present invention none.
또 본 발명에서는 인조석 판재 제조시 30ton의 압력을 가하여 압축, 성형하여 인조석 블럭을 제조하고 있어서 100℃ 이하에서 열처리하는 공정을 적용하여 건축용 내·외장재로서 요구되는 물성인 압축강도 600kg/㎠ 이상인 인조석 판재를 제조할 수 있는 것을 특징으로 한 것으로 기공개된 제853호에서는 이러한 공정을 적용하지 않았다.In addition, in the present invention, artificial stone blocks are manufactured by applying a pressure of 30 tons to manufacture artificial stone blocks by applying a pressure of 30 tons, and applying heat-treatment at 100 ° C. or lower, and having a compressive strength of 600 kg / cm 2 or more, which is required as a building interior and exterior material. No. 853, which was disclosed as being characterized by being able to produce, did not apply this process.
따라서 본 발명은 기존의 공정을 개선하여 제품의 압축강도를 현저히 향상시킬 수 있는 제조공정을 특징으로 한 것이다.Therefore, the present invention is characterized by a manufacturing process that can significantly improve the compressive strength of the product by improving the existing process.
그리고 또 본 발명에서는 첨가제의 양을 기공개된 기술보다 현저히 적게 사용하여 인조석 판재를 제조하므로 제조원가 상승요인을 낮춘 반면, 물성이 개선된 인조석 판재 제조방법을 특징으로 하는 것이다. 즉, 고가인 메칠에틸케톤퍼옥사이드 및 코발트나프타네이트의 첨가량을 상기 기술보다 각각 2.2~4.4배, 10-12배 적게 사용하여 제조하였으며 이때 제조된 인조석 판재의 압축강도는 620-650kg/㎠ 이었으며 상기 기술에 의한 제조법으로는 제조한 제품의 압축강도 보다 200kg/㎠를 상회할 수 없는 비실용적인 기술이다.In addition, the present invention is characterized by a method of manufacturing artificial stone plate material, while improving the physical properties, while lowering the manufacturing cost increase factor because the production of artificial stone plate using a significantly less amount than the disclosed technology. In other words, the amount of expensive methyl ethyl ketone peroxide and cobalt naphthanate added was 2.2 to 4.4 times and 10-12 times less than the above technique, respectively, and the compressive strength of the manufactured artificial stone plate was 620-650 kg / ㎠ and It is an impractical technique that can not exceed 200kg / cm 2 than the compressive strength of the manufactured product by the manufacturing method by technology.
따라서 본 발명에서는 상기와 같은 문제점을 개선하여 기존의 인조석 판재보다 제품의 제조원가가 압축강도와 생산성이 우수하고 폐기물인 석분울 90% 사용하여 폐자원의 활용을 극대화한 인조석 판재를 제조하는데 그 목적이 있다.Therefore, the present invention improves the above problems, the manufacturing cost of the product is superior to the existing artificial stone plate, the compression strength and productivity is excellent, and the purpose of manufacturing the artificial stone plate to maximize the utilization of waste resources by using 90% of stone stone waste. have.
이하 본 발명을 설명한다.Hereinafter, the present invention will be described.
본 발명은 국내 황등산 화강석 및 봉화산 백운석 폐기물을 건조한 후 이에 수지와 미량의 부가제를 첨가, 혼합하여 철재형틀에 투여하여 일정압력 이상으로 압축, 성형한 후 성형물을 100℃ 이하에서 열처리하여 제품의 질감, 문양 및 압축강도가 천연석 판재와 유사한 본 발명이 종래의 방법과 근본적으로 상이한 것은 폐기물 석분과 수지를 혼합하여 압축성형하므로 종래의 수지 사용량 25-30%를 10%로 감소시키고 석분과 수지를 혼합할 때 스며드는 기포를 완전히 제거할 수 있으며, 압축강도를 종래의 방법보다 향상시키고 100℃ 이하의 낮은 온도에서 열처리하므로서 에너지소비를 줄일 수 있으며 생산성을 향상시킬 수 있는 점이다.The present invention is to dry the domestic Hwangdeungsan granite and Bonghwasan dolomite waste, add resin and a small amount of additives, mix and administer to the steel mold, compress and mold the mold at a certain pressure or higher, and then heat-treat the molded product at 100 ℃ or lower, and the texture of the product. In the present invention, which is similar to the natural stone plate, the pattern and the compressive strength are fundamentally different from those of the conventional method, the waste molding powder and the resin are mixed and molded to reduce the conventional resin consumption by 25-30% to 10% and mix the stone powder and the resin. When it is possible to completely remove the air bubbles, the compressive strength is improved compared to the conventional method and heat treatment at a lower temperature of less than 100 ℃ energy consumption can be reduced and productivity can be improved.
