방수 및 단열 성능이 우수한 페인트 및 그 제조방법{Excellent waterproof and insulation performance paint and manufacturing method thereof}[0001] The present invention relates to a paint excellent in waterproofing and insulation performance,

본 발명은 방수 및 단열 성능이 우수한 페인트에 관한 것으로서, 보다 구체적으로 수용성으로 구성되어 작업성이 향상되고, 방수 및 단열 성능은 물론 방오성, 내수성, 내약품성, 접착력 등의 물성이 크게 향상되며 건축물의 실내는 물론 건축물의 외벽과 터널 내벽 등에 내구성이 우수한 마감용 도막을 형성할 수 있는 방수 및 단열 성능이 우수한 페인트 및 그 제조방법에 관한 것이다.The present invention relates to a paint excellent in waterproofing and heat insulation performance, and more specifically, it is made water-soluble to improve workability, and waterproofing and insulation performance as well as physical properties such as antifouling property, water resistance, chemical resistance, The present invention relates to a paint excellent in waterproof and heat insulating performance capable of forming a coating film for finishing excellent in durability, such as an outer wall of a building and an inner wall of a tunnel, and a method of manufacturing the same.

일반주택, 아파트, 및 업무용 또는 상업용 건물의 경우 사람이 거주하거나 각종 활동을 하는 공간이므로, 인간이 안전하면서도 쾌적하게 생활을 영위할 수 있는 조건을 만족시키도록 그 내장재 등이 개선되고 발전되어 오고 있다.In general houses, apartments, and commercial or commercial buildings, people are living or doing various activities. Therefore, their interior materials have been improved and developed so as to satisfy the conditions that enable people to live comfortably and comfortably .

일반적으로 종전의 주택을 포함한 건물들은 조습성, 방로성은 양호하였지만, 최근에는 건축물의 고기밀화가 추진되고, 내화성, 기밀성을 중시한 새로운 건재가 많이 사용되고 있다.Generally, buildings including old houses have good humidity control and insulation properties. Recently, however, meat is becoming more dense in buildings and new construction materials emphasizing fire resistance and airtightness are being used.

그러나 이러한 새로운 건자재들은 다음과 같은 문제들을 야기하고 있다.However, these new materials cause the following problems.

즉, 건재 표면에 결로가 발생되어 건물의 쾌적성 및 내구성을 저하시킬 뿐만 아니라, 결로에 의해 발생한 수분이 곰팡이나 진드기의 발생을 초래하여 인체의 건강에 나쁜 영향을 미친다.In other words, condensation is generated on the surface of the building material to deteriorate the comfort and durability of the building, and moisture generated by condensation causes mold and mites, which adversely affects the health of the human body.

특히, 겨울철에는 건물 내부의 밀폐성이 높아져 공기가 건조해질 수 있으며, 그에 따라 피부도 건조해져서 신체 일부에 각질이 생겨나고, 가려운 곳이 발생하여 아토피성 피부질환이 악화된다. 이러한 문제점을 다소나마 해결하기 위하여 일반적으로 빨래를 방안에 널어놓거나 가습기를 가동시키기도 하는데, 이 경우, 번거로울 뿐만 아니라 많은 에너지의 사용이 필요하게 된다.Especially in winter, air tightness inside the building increases, and the skin becomes dry due to the dryness of the skin, resulting in keratinization of the body part, and itching of the body, which makes the atopic skin disease worse. In order to solve this problem, the laundry is generally installed in a room or the humidifier is operated. In this case, not only the troublesome but also the use of a lot of energy is required.

최근에는 조습기능을 갖는 벽지, 타일 또는 패널들의 시공에 의해 피부질환을 완화시키고자 하는 시도가 있었다. 일반적으로 시중에서 탄성코트라고 불리우는 두꺼운 도막의 바름재와 같이 조습기능을 갖는 제품을 시공할 경우, 흡습에 따른 벽면의 결로를 방지할 수 있지만 높은 흡습 외 방습기능이 없어 곰팡이나 세균류의 번식이 촉진되어 기침, 감기, 비염 또는 천식과 같은 호흡기질환을 일으키는 문제점이 있었다.In recent years, attempts have been made to alleviate skin diseases by the construction of wallpaper, tiles or panels having a humidity control function. Generally, when a product having a humidity control function such as a thick coating film called an elastic coat in the market is installed on the market, it is possible to prevent condensation on the wall due to moisture absorption, but it does not have a high moisture absorption and moisture proofing function and promotes the growth of fungi and bacteria Causing respiratory diseases such as cough, cold, rhinitis or asthma.

또한 습도가 비교적 높은 여름철에도 제품의 과도한 흡습에 따른 문제점을 내포하고 있다.In addition, even in the summer when the humidity is relatively high, the product suffers from excessive moisture absorption.

이와 같은 종래의 각종 흡습기능을 갖는 기능성 타일 또는 패널의 경우, 흡착, 탈취, 흡습이라는 기능적인 면만을 강조하는 경향이 있었을 뿐, 곰팡이나 세균류의 번식의 억제할 수 있는 흡습 및 방습기능이 복합적으로 기능하는 제품은 없었다. 또한, 최근 널리 활용되고 있는 가습기에 흡착, 탈취, 흡습 등의 기능이 부가된 복합 기능의 제품을 사용하는 경우 제품 내부의 결로와 미 세척 등의 관리부실로 인하여 녹농균(Pseudomonasaeruginosa), 폐렴간구균(Klebsiella pneumoniae), 황색포도상구균(Staphylococcus aureus), 알러지(allergy)와 천식(asthma) 등을 유발시키는 클래도스포리움균(cladosporium), 알터나리아균(Alternaria) 등의 병원성 미생물이 발생되는 문제점이 있다.Such conventional functional tiles or panels having various hygroscopic functions tend to emphasize only functional surfaces such as adsorption, deodorization, and moisture absorption, and have a combination of moisture absorption and moisture-proof functions capable of suppressing the growth of fungi and fungi There was no functioning product. In addition, when a multifunctional product having a function of adsorption, deodorization, moisture absorption, etc. is added to a humidifier which has been widely used recently, it is difficult to control the pseudomonas aeruginosa, pneumococcus There is a problem that pathogenic microorganisms such as Cladosporium and Alternaria which cause Klebsiella pneumoniae, Staphylococcus aureus, allergy and asthma are generated have.

이러한 문제점을 해결하기 위하여 실내 습도에 따라 흡습 작용 또는 방습 작용이 이루어짐으로써, 결로의 방지, 항균성, 내오염성 기능을 갖는 최적의 벽 또는 천장 바름용 기능성 실내용 페인트의 개발이 요구된다.In order to solve these problems, it is required to develop a functional interior paint for an optimal wall or ceiling wool which has a moisture absorption function or a moisture proofing function according to room humidity, and has a function of preventing condensation, antibacterial property and stain resistance.

이러한 문제를 해결하기 위해 대한민국 등록특허 제10-1535151호에서는 물 10 내지 20 중량부와, 바인더 10 내지 30 중량부와, 제 1 무기안료 20 내지 40 중량부, 및 제 2 무기안료 10 내지 25 중량부를 포함하는 흡습성 및 방습성을 가지는 기능성 실내용 건축마감재 조성물에 있어서, 상기 제 1 무기안료가 규조토, 백토, 황토, 차점토, 알로펜, 패분, 이산화규소, 산화칼슘, 수산화칼슘, 탄산칼슘, 숯, 활성탄, 벤토나이트, 버미큘라이트, 세피올라이트, 제올라이트, 포졸란 및 마크로시멘트로 이루어진 군에서 하나 이상 선택되는 다공질의 분상체 15 내지 25 중량부; 소다장석 20 내지 30 중량부; 내화점토 20 내지 30 중량부; 도석 15 내지 25 중량부; 토르말린 5 내지 15 중량부; 및 흑활석 5 내지 15 중량부를 포함하는 것을 특징으로 하는 흡습성 및 방습성을 가지는 기능성 실내용 건축마감재 조성물이 개시되어 있다.In order to solve this problem, Korean Patent No. 10-1535151 discloses an ink composition comprising 10 to 20 parts by weight of water, 10 to 30 parts by weight of a binder, 20 to 40 parts by weight of a first inorganic pigment, and 10 to 25 parts by weight of a second inorganic pigment Wherein the first inorganic pigment is at least one selected from the group consisting of diatomaceous earth, clay, loess, tea clay, allopen, peat, silicon dioxide, calcium oxide, calcium hydroxide, 15 to 25 parts by weight of a porous particulate material selected from the group consisting of activated carbon, bentonite, vermiculite, sepiolite, zeolite, pozzolan and macrocement; 20 to 30 parts by weight of feldspar; 20 to 30 parts by weight of refractory clay; 15 to 25 parts by weight of stones; 5 to 15 parts by weight of tourmaline; And 5 to 15 parts by weight of talc. The present invention relates to a functional interior trim material composition having hygroscopicity and moisture resistance.

그러나, 상기 등록특허는 흡습 작용을 하기 때문에 건축물의 외부 벽면의 방수용으로는 적합하지 않고 흡습과 방습이 반복되면서 내수성이 저하되고 접착력도 저하되는 문제가 있었다.However, since the above-mentioned patent has a hygroscopic action, it is not suitable for waterproofing the outer wall surface of the building, and the moisture resistance and humidity resistance are repeated, so that the water resistance is lowered and the adhesive strength is lowered.

따라서 건축물 실내 마감재는 물론, 실외 마감재, 터널 내벽 등에도 광범위하게 적용할 수 있는 방수 및 단열 페인트의 개발이 필요한 실정이다.Therefore, it is necessary to develop waterproof and heat insulating paint that can be widely applied not only to interior finishing materials for buildings but also to outdoor finishing materials and inner walls of tunnels.
