Abstract
Description
본 발명은 이액 경화형 방염 코팅제 조성물 및 그 제조방법에 관한 것으로, 좀 더 상세하게는 알콕시실란, 산, 테트라 에틸 오르토 실리케이트, 기능성 충진제, 금속산화물, 에탄올, 티타늄 옥사이드, 에폭시레진을 포함하여 구성되는 것을 특징으로 하는 이액 경화형 방염 코팅제 조성물 및 상기 조성물을 소정의 비율로 혼합하고, 작은 입자로 추출하여 목재 제품에 도포하는 이액 경화형 방염 코팅제 제조방법에 관한 것이다. The present invention relates to a two-component curable flame retardant coating composition and a method for preparing the same, and more particularly, to an alkoxysilane, an acid, tetraethyl ortho silicate, a functional filler, a metal oxide, ethanol, titanium oxide, and an epoxy resin. It relates to a two-component curable flame retardant coating composition characterized in that the composition and the composition is mixed in a predetermined ratio, extracted into small particles and applied to a wood product, a method for producing a two-component curable flameproof coating composition.
본 발명에 의한 방염 코팅제를 활용하면, 상온에서 빠른 시간 내에 경화되어 작업이 쉽고, 냄새가 없으며, 코팅층이 장기간 유지되고, 인체에 무해하고 환경오염을 유발하지 않는 장점이 있다.When using the flame-retardant coating according to the present invention, it is hardened at a rapid time at room temperature, easy to work, there is no smell, the coating layer is maintained for a long time, harmless to the human body and does not cause environmental pollution.
근래에 들어 새집 증후군 및 새 가구 증후군의 문제가 심각하게 대두되면서 그 원인에 대한 연구가 가속화되었고 그 결과 그 원인의 상당 비율이 목재 제품에 기인한다는 사실을 알게 되었다. 이에 따라 소비자의 목재 제품에 대한 인식이 많이 변화되고 정부 방침도 보다 엄격해지면서 목재 제품의 친환경적 가공에 대한 관심도 증대되고 있다. 이러한 사회적 요구에 편승하여 최근 건축자재 또는 가구 등에 사용되는 불연성, 난연성 처리제에도 친환경 제품으로 제조하고 있는 추세이다.
In recent years, the problems of sick house syndrome and new household syndrome have emerged seriously, and research on the cause has accelerated, and as a result, a large percentage of the causes are found to be due to wood products. As a result, consumers' perceptions about wood products have changed and government policies have become more stringent, and interest in environmentally friendly processing of wood products is increasing. In response to such social demands, recent trends have been made of eco-friendly products for non-combustible and flame retardant treatment agents used in building materials or furniture.
일반적으로 마루 판재로는 원목, MDF, HDF 판재가 사용된다. 그리고, 마루 판재의 표면처리는 통상적으로 원목에 UV 코팅을 하거나, MDF, HDF 판재에 필름을 붙여 마감처리하는 방식을 활용한다.
Generally, wood, MDF, and HDF board are used as floor boards. In addition, the surface treatment of the floorboard is usually UV coating on the wood, or MDF, HDF board using a method of finishing the film by attaching the film.
이 중에서 원목에 UV 코팅한 제품은 원목의 질감을 최대한 부각시킬 수 있다는 장점이 있으나, 가격이 상대적으로 비싸 가격경쟁력이 떨어지고, 국내 원자재 부족으로 중국 또는 인도네시아 등지에서 수급하여 사용된다는 단점이 있다. 또한, 원목의 특성상 화재에 취약하다는 단점도 가지고 있다.
Among them, UV coated products have the advantage of being able to highlight the texture of the wood as much as possible, but the price is relatively expensive, the price competitiveness is low, and there is a disadvantage that it is supplied and used in China or Indonesia due to lack of domestic raw materials. In addition, the nature of the wood has the disadvantage of being vulnerable to fire.
한편, MDF, HDF 등에 필름을 붙여 사용하는 제품은 원목의 취약점인 화재의 발생 가능성을 보완하였으나, 일단 화재가 발생하면 유독가스의 배출량이 많고, 합성목의 특성상 수분에 약하여 내구성이 원목보다 약하다는 단점이 있다. 또한, MDF, HDF로부터 필름이 쉽게 박리된다는 단점도 가지고 있다.
On the other hand, MDF, HDF, etc. film used to supplement the possibility of the fire, which is a weakness of the wood, but once the fire occurs, the emission of toxic gas is high, and due to the nature of synthetic wood, it is weak in moisture and weak in durability. There are disadvantages. It also has the disadvantage that the film peels easily from MDF and HDF.
따라서, 근래에는 목재 제품에 난연제를 도포하여 처리하는 방식을 주로 사용하고 있는데, 그중에서도 삼산화 안티몬이 주종을 이룬다. 그러나, 상기 재료는 굵은 입자상의 산화물질로 인한 산란현상으로 재료에 도포하면 원재료의 광택을 저하시키고, 비교적 낮은 화학 반응성으로 난연 효과가 낮으며, 그 비중이 높아 도포하려는 원재료와의 결합력이 낮다는 단점이 있다.
Therefore, in recent years, a method of applying a flame retardant to wood products is mainly used, and antimony trioxide is mainly used. However, when the material is applied to the material due to the scattering phenomenon due to the coarse particle oxide, the gloss of the raw material is lowered, and the flame retardant effect is low due to the relatively low chemical reactivity, and the specific gravity is high, so that the bonding strength with the raw material to be applied is low. There are disadvantages.

본 발명은 이액 경화형 방염 코팅제 조성물 및 그 제조방법에 관한 것이다. The present invention relates to a two-component curable flame retardant coating composition and a method for producing the same.
본 발명에 의한 이액 경화형 방염 코팅제 조성물은 알콕시실란, 테트라 에틸 오르토 실리케이트, 기능성 충진제, 금속 산화물 및 에탄올로 구성되어 있다.
The two-component curable flame retardant coating composition according to the present invention is composed of alkoxysilane, tetra ethyl ortho silicate, functional filler, metal oxide and ethanol.
상기 알콕시실란은 R1-S-(OR2)3 또는 S(OR2)4로부터 선택될 수 있으며, 상기 식에서 R1은 탄화수소기, 비닐기, 글리시딜기, 아미노기 중 어느 하나이고, R2는 탄화수소기이다. 상기 알콕시실란 중에서도 본 발명에서는 메틸 트리 메톡시실란을 사용하였을 때 테트라 에틸 오르토 실리케이트와 반응율이 크지만, 에틸 트리 메톡시실란, 페닐 트리 메톡시실란, 테트라 에톡시실란 등을 사용하거나 상기 알콕시실란을 선택적으로 혼합하여 사용할 수도 있다. 이 경우, 초산, 인산, 붕산, 염산, 질산, 황산 중 어느 하나를 첨가하여 반응시키면 그 반응속도를 증가시킬 수 있다.

In addition, titanium oxide may be further added to the present invention. The titanium oxide is a well-known non-toxic substance, and the addition of titanium oxide to the present invention may improve the adhesiveness of the present invention. In other words, when the titanium oxide as a photocatalyst was added, the initial tackiness was high and the tackifying effect was improved even after drying.
한편, 본 발명에는 에폭시 레진을 더 포함하여 구성될 수 있다. 에폭시 레진은 산성 촉매가 있는 상태의 상승된 온도에서 에폭시기와 반응하는, 하이드록시기 및/또는 티올기와 같은, 에폭시기와는 다른 반응기들을 포함한다. 에폭시 수지들은 에폭시기보다 더 많은 반응기, 예를 들어, 더 많은 하이드록시기들을 포함할 수 있다. 본 발명에서, 에폭시 수지들은 입자 크기가 300 내지 1,000㎚ 범위이고, 평균 분자량은 400 내지 8,000 범위를 활용하는 것이 바람직하다. 그리고, 분자당 약 5개의 하이드록식와 2개의 에폭시기를 갖는 것이 좋다.
On the other hand, the present invention may further comprise an epoxy resin. Epoxy resins include reactors different from epoxy groups, such as hydroxyl groups and / or thiol groups, that react with epoxy groups at elevated temperatures with an acidic catalyst. Epoxy resins may include more reactors than epoxy groups, for example, more hydroxyl groups.

In addition, in the present invention, isophthalic / neopentyl glycol resin may be dissolved in styrene and various additives may be added to enhance the flame retardant effect. Isophthalic / neopentyl glycol resin is a relatively small molecular weight resin, which is a type of unsaturated polyester resin. Dissolving the resin in styrene and adding methyl ethyl ketone peroxide causes a polymer reaction of the isophthalic / neopentyl glycol resin. The polymer reaction may be performed by dissolving 100 parts by weight of isophthalic / neopentyl glycol resin in 20 to 40 parts by weight of styrene, and adding 0.5 to 2 parts by weight of methyl ethyl ketone peroxide relative to 100 parts by weight of the solution. Increases. Addition of silica to this increases the uniformity of the coating liquid and improves the flame retardant effect. In addition, alumina trihydrate fills the irregular surface of wood, making the surface smooth and beautiful after coating. In addition, urethane acrylate and methyl methacrylate serve as an adjuvant to further enhance the flame retardant effect of the present flame retardant. In addition, when calcium hydroxide and cobalt are added in the polymer reaction of the isophthalic / neopentyl glycol resin, the polymer reaction may be accelerated to significantly improve the flame retardant effect.
