Description

모래 및 자갈의 항균성 착색가공방법{Antibacterial Coloring Method of Sand & Gravel}Antibacterial Coloring Method of Sand & Gravel}

종래에 수족관, 어항, 관상용 화분에 사용하는 모래나 조약돌에 미려한 외관의 구성ㆍ유지를 위하여 에폭시 페인트 등 합성수지 도료 착색제를 도포하여 사용하였으나 통상의 에폭시 페인트 등 합성수지 도료 착색제는 착색제 차체로서는 형성된 도막(塗膜)의 내수성, 내약품성, 내마모성, 색상 등이 우수하다는 장점을 갖고 있으나 물 속이나 온ㆍ습도 변화가 많은 기후조건에서 외기에 노출되었을 때에는 에폭시 등 합성수지 도막의 내ㆍ외부에 박테리아 및 곰팡이 등이 부착ㆍ번식함으로 인하여, 단 기간 내에 수조 또는 어항의 물이 부패하거나 흐려지고, 관상용 화분의 경우 물 때 및 이끼가 끼어서 악취가 발생하고 외관 상태도 불량하게 되어 관상용으로서의 가치를 상실하는 문제점을 갖고 있다.In the past, synthetic resin paints such as epoxy paints were used by applying sand or pebbles to the sand, pebbles used in aquariums, fish tanks, ornamental pots, and synthetic resin paints such as epoxy paints. Iii) It has the advantages of excellent water resistance, chemical resistance, abrasion resistance, color, etc., but when exposed to outdoor air under water or climatic conditions with a lot of temperature and humidity changes, bacteria and mold inside and outside of synthetic resin coating film such as epoxy Due to attachment and propagation, water in the tank or fish tank becomes decayed or blurred within a short period of time, and in the case of ornamental flower pots, water and moss get caught, odors occur and appearance is poor, resulting in the loss of ornamental value. .

본 발명은 위에서 설명한 문제점을 해결하기 위하여, 원적외선방사 목적으로 실리카, 대전방지 목적으로 알루미나, 항균ㆍ가스분해목적으로 은이온, 동이온, 아연이온, 티탄이온 등 금속이온, 가스흡착ㆍ제습목적으로 제오라이트 등 각소재로 이루어 지며, 강력한 항균기능과 탈취기능,ㆍ정전기제거기능, 원적외선 방출기능을동시에 그리고 반영구적으로 발휘하는 미크론단위의 분말상태의 무기(無機)항균제를 종래의 에폭시 페인트 등 합성수지 도료에 첨가하여 항균성 합성수지 도료 착색제를 제조하고 이를 모래 및 조약돌에 도포하여 사용함으로서 미려한 외관의 구성ㆍ유지라는 사용목적에 최적인 상태를 통상의 에폭시 페인트 등 합성수지 도료를 도포한 모래 및 조약돌을 사용한 경우에 비해 월등하게 장기간 유지시켜주는 방법을 제공한다.The present invention is to solve the problems described above, silica for far-infrared radiation, alumina for antistatic purposes, silver ions, copper ions, zinc ions, titanium ions, such as titanium ions for antibacterial and gas decomposition purposes, gas adsorption and dehumidification purposes It is composed of various materials such as zeolite, and it is a micron powder inorganic antimicrobial agent that exhibits strong antibacterial function, deodorization function, electrostatic removal function, and far infrared emission function simultaneously and semi-permanently. By adding an antimicrobial synthetic resin paint colorant and applying it to sand and pebble, it is optimal to be used for the purpose of construction and maintenance of beautiful appearance compared to the case of using sand and pebble coated with synthetic resin paint such as epoxy paint. It provides a way to maintain superior long-term maintenance.

지금까지 수조, 어항 및 관상용 화분에 사용하는 모래 및 조약돌에 미려한 외관을 구성ㆍ유지하기 위하여 모래 및 조약돌 위에 통상의 에폭시 페인트 등 합성수지 도료 착색제를 도포하여 사용하여왔다. 그러나 통상의 에폭시 페인트 등 합성수지 도료 착색제를 도포한 모래 및 조약돌이 물 속이나 온ㆍ습도 변화가 많은 기후조건에서 외기에 노출되었을 때에는 에폭시 등 도막의 내ㆍ외부에 박테리아 및 곰팡이 등이 부착ㆍ번식함으로 인하여, 단 기간 내에 수조 또는 어항의 물이 부패하거나 흐려지고, 관상용 화분의 경우 물 때 및 이끼가 끼어서 악취가 발생하고 외관 상태도 불량하게 되어 관상용으로서의 가치를 상실하는 문제점을 갖고 있다. 이를 개선하기 위한 방법으로 형성된 에폭시 등 합성수지 도막 내외부에 박테리아나 곰팡이가 부착ㆍ번식하는 것을 방지하기 위하여, 모래 및 조약돌 위에 통상의 에폭시 페인트 등 합성수지 도료 착색제를 도포하고나서 건조후 형성된 에폭시 등 합성수지 도막위에 세균억제 또는 멸균의 목적으로 유기소독제제를 추가로 분무하여 도포하거나, 통상의 에폭시 페인트 등 합성수지 도료 착색제에 신너와 함께 유기 소독제를 첨가하여 도포하는 등의 방법을 사용하였으나, 유기 소독제 자체의 불쾌한냄새와 강한 독성 때문에 사용상 제약이 많았고 사용자체를 기피하는 경향이 많았다. 또한 종래의 유기 소독제는 화학물질 자체의 화학반응을 이용한 것으로서, 일반적으로 유기 화학물질은 수일 또는 수주 내에 자외선 및 산소 등의 산화작용에 의해 분해되어 버리고 마는 특성이 있기 때문에, 효과가 짧은 시간 밖에 지속되지 못하므로 도막의 내외부에 세균이나 곰팡이가 번식하는 것을 방지할 수 없었고 결과적으로 수조, 어항 및 관상용 화분의 미려한 외관의 구성ㆍ유지하기 위해 사용한 착색된 모래 및 조약돌의 사용목적을 달성할 수 없었다.Until now, in order to construct and maintain a beautiful appearance in sand and pebbles used in tanks, fish tanks and ornamental pots, synthetic resin paint colorants such as ordinary epoxy paints have been applied to sand and pebbles. However, when sand and pebble coated with a synthetic resin paint colorant such as ordinary epoxy paint are exposed to the air in water or in climatic conditions with a great change in temperature and humidity, bacteria and molds adhere to and grow inside and outside the epoxy film. Due to this, the water in the tank or fish tank is decayed or blurred within a short period of time, and in the case of the ornamental potted plants, there is a problem in that the smell and moss caused by the bite and moss are caught and the appearance is also poor, thereby losing the value for ornamental use. In order to prevent bacteria and mold from adhering and propagating on the inside and outside of the synthetic resin coating film formed by the method for improving this, a synthetic resin paint colorant such as ordinary epoxy paint is applied on sand and pebble, and then dried on the synthetic resin film such as epoxy formed after drying. For disinfection or sterilization purposes, an organic disinfectant was applied by spraying additionally, or an organic disinfectant was added to the synthetic resin paint colorant such as an ordinary epoxy paint with a thinner. However, an unpleasant smell of the organic disinfectant itself was used. Due to the strong toxicity and strong usage, there was a tendency to avoid users. In addition, conventional organic disinfectants use chemical reactions of chemicals themselves. Generally, organic chemicals are decomposed by oxidation such as ultraviolet rays and oxygen within a few days or weeks. As a result, it was not possible to prevent the growth of bacteria and mold inside and outside the coating film, and as a result, the purpose of using the colored sand and pebbles used to construct and maintain the beautiful appearance of the tank, the fish tank, and the ornamental flower pot was not achieved.

본 발명은 에폭시 페인트 등 합성수지 도료 착색제의 원료성분으로 무독ㆍ무해하며 그 효과가 반영구적으로 발현되는 무기 항균제를 첨가하여 항균성 합성수지 도료 착색제를 제조하고 이를 모래 및 조약돌 위에 도포하여 수조, 어항 및 관상용 화분에 사용함으로서, 종래의 에폭시 페인트 등 합성수지 도료 착색제의 장점은 조금도 손상시키지 않고 그대로 유지하면서도 세균이나 곰팡이 등이 에폭시 등 합성수지 도막 내 외부에 부착ㆍ번식하지 못하도록 하여 미려한 외관의 구성ㆍ유지라는 본래의 사용목적에 최적인 상태를 통상의 종래의 에폭시 페인트 등 합성수지 도료 착색제를 도포한 경우보다 월등하게 장기간 유지시켜주는 방법을 제공한다.The present invention is a non-toxic and harmless as a raw material of synthetic resin paint colorants such as epoxy paint, and the addition of inorganic antimicrobial agent that the effect is semi-permanent to produce an antimicrobial synthetic resin paint colorant and apply it on sand and pebble to water tanks, fish tanks and ornamental pots By using it, the advantages of synthetic resin colorants such as epoxy paints are maintained without any damage, while preventing bacteria and molds from adhering and propagating inside and outside of synthetic resin coatings such as epoxy. The present invention provides a method of maintaining the optimum state for a long time superior to the case of applying a synthetic resin colorant such as a conventional conventional epoxy paint.

본 발명은 위에서 설명한 기술적 과제를 달성하기 위하여, 원적외선방사 목적으로 실리카, 대전방지 목적으로 알루미나, 항균ㆍ가스분해목적으로 은이온, 동이온, 아연이온, 티탄이온 등 금속이온, 가스흡착ㆍ제습목적으로 제오라이트 등 각소재로 이루어 지며, 강력한 항균기능과 탈취기능ㆍ정전기제거기능, 원적외선 방출기능을 동시에 그리고 반영구적으로 발휘하는 미크론단위의 분말상태의 무기(無幾)항균제를 종래의 에폭시 페인트 등 합성수지 도료 착색제에 첨가하여 항균성 에폭시 페인트 등 합성수지 도료 착색제를 제조하여 이를 모래 및 조약돌에 도포하여 사용함으로서 본래의 미려한 외관의 구성ㆍ유지라는 사용목적에 최적인 상태를 종래의 에폭시페인트 등 합성수지 도료 착색제에 비해 월등하게 장기간 유지시켜주는 방법을 제공한다.The present invention, in order to achieve the above technical problem, silica for far-infrared radiation purposes, alumina for antistatic purposes, silver ions, copper ions, zinc ions, titanium ions, such as titanium ions for antibacterial and gas decomposition purposes, gas adsorption, dehumidification purposes It is composed of various materials such as zeolite, and it is a micron powder inorganic antimicrobial agent that exhibits strong antibacterial function, deodorizing function, electrostatic removal function, and far infrared emission function simultaneously and semi-permanently.
