The present invention relates to a waterproofing agent applied to the side of a wood plywood for furniture, and more particularly, to a waterproofing agent for wood furniture for preventing deformation of a connecting part between members due to moisture absorption of wood furniture, or detachment of adhered finishing material.
목재 가구에 대해 방수-방습 처리를 하기 위해서는 목재 가구용 패널 제조시 왁스를 첨가하거나 접착제의 첨가량을 증량시키는 방법 등이 있으나, 그 효과가 크지 않다. MDF, HDF, P, B 등의 압축 목재 판재는 위와 같은 방법으로 처리된 것임에도 불구하고, 습기나 물에 접하게 되면 형태가 부풀어 가구 변형과 하자의 원인이 된다.
Waterproofing of wood furniture - A method of damp-proofing is to add wax or increase the amount of adhesive to be added when manufacturing a wooden furniture panel, but the effect is not significant. Compressed wood boards such as MDF, HDF, P, and B are processed in the same manner as above, but if they come into contact with moisture or water, the shape will swell and cause furniture deformation and defects.

On the other hand, the urethane compound can exhibit elasticity in a high hardness state according to mechanical properties such as toughness, flexibility, chemical resistance, low temperature curability, corrosion resistance and adhesiveness and degree of compounding, and has excellent chemical properties. Due to these properties, the urethane compound is widely applied in many fields. The inventors of the present invention have conducted studies to apply a urethane compound as a base component of a waterproofing agent for wood furniture, since they are used variously as paints, foams, flooring materials, waterproofing materials and sealing materials.
다만 이러한 우레탄 화합물에 기반을 둔 목재 가구용 방수제로 적용하기 위해서는 상온 하에서 방치한 경우에도 겔화 등을 일으키지 않는 뛰어난 보존 안전성이 요구되면서도, 적정 점도가 있어 도포 작업시 흘러 내림이 없어야 하고, 도포 작업 후에는 빠르게 경화해야 한다. 또한, 방수제 도포, 경화 후에도 어느 정도의 탄성이 있어 부스러지거나 탈리되지 않아야 하며, 인체 유해 물질의 혼용이 배제되어야 한다.
However, in order to be applied as a waterproofing agent for wood furniture based on such a urethane compound, excellent preservation safety that does not cause gelation even when left under normal temperature is required, and there is no proper flow of viscosity at the time of application, Cure quickly. In addition, after the application of the waterproofing agent and curing, it should have some elasticity so that it should not be crumbled or desorbed, and the mixture of human harmful substances should be excluded.

본 발명은 「우레탄수지(urethane resin) 100중량부; 메틸아세테이트 100~300중량부; 에폭시화합물(epoxy compounds) 20~30중량부; 실란화합물(silane compounds) 10~20중량부; 폴리부텐(Polybutene) 5~10중량부; 및 폴리머릭 엠디아이(polymeric MDI) 1 ∼ 5중량부; 가 혼합된 목재 가구용 방수제」를 제공한다.The present invention relates to a urethane resin composition comprising 100 parts by weight of a urethane resin; 100 to 300 parts by weight of methyl acetate; 20 to 30 parts by weight of epoxy compounds; 10 to 20 parts by weight of silane compounds; 5 to 10 parts by weight of polybutene; And 1 to 5 parts by weight of polymeric MDI; Waterproofing agent for wood furniture mixed with water ".

In the present invention, rosin having a specific gravity of 1.045 to 1.086 may be further added in an amount of 10-15 parts by weight based on 100 parts by weight of the methyl acetate, thereby further improving the tackiness before curing and the durability after curing.

본 발명은 「우레탄수지(urethane resin) 100중량부; 메틸아세테이트 100~300중량부; 에폭시화합물(epoxy compounds) 20~30중량부; 실란화합물(silane compounds) 10~20중량부; 폴리부텐(Polybutene) 5~10중량부; 및 폴리머릭 엠디아이(polymeric MDI) 1 ∼ 5중량부; 가 혼합된 목재 가구용 방수제」를 제공한다.
The present invention relates to a urethane resin composition comprising 100 parts by weight of a urethane resin; 100 to 300 parts by weight of methyl acetate; 20 to 30 parts by weight of epoxy compounds; 10 to 20 parts by weight of silane compounds; 5 to 10 parts by weight of polybutene; And 1 to 5 parts by weight of polymeric MDI; Waterproofing agent for wood furniture mixed with water ".
상기 우레탄수지는 수산기값이 100~250mgKOH/g인 폴리올을 이소시아네이트와 반응시켜 수득한 것을 적용할 수 있다. 우레탄수지의 수산기값은 접착성능에 관계된 것으로서, 수산기값이 100mgKOH/g 미만인 경우에는 응집력이 충분치 아니한 문제점이 발생할 수 있고, 수산기값이 250mgKOH/g을 초과하는 경우에는 접착력이 떨어질 수 있다. 상기 우레탄수지 수득을 위한 이소시아네이트의 사용량은 폴리올 100중량부에 대하여 10~20중량부가 적절하다.
The urethane resin may be obtained by reacting a polyol having a hydroxyl value of 100 to 250 mgKOH / g with an isocyanate. The hydroxyl value of the urethane resin is related to the adhesion performance. When the hydroxyl value is less than 100 mgKOH / g, the cohesive force may not be sufficient. When the hydroxyl value is more than 250 mgKOH / g, the adhesive strength may decrease. The amount of the isocyanate used for obtaining the urethane resin is suitably 10 to 20 parts by weight based on 100 parts by weight of the polyol.
상기 메틸아세테이트(CH3COOCH3)는 물과 다른 유기용매들과의 용해성이 뛰어나며, 과일향기가 나는 무색 용매로서, 뛰어난 용해능력 때문에 라커나 페인트 제거제의 용매나 사용된다. 메틸아세테이트는 손톱 손질용(nail polish remover)으로 사용할 수 있을 정도로 안전하고, 끓는점이 57℃ 이기 때문에 용매의 증발속도를 빠르게 한다. 상기 메틸아세테이트를 우레탄수지 100중량부 대비 100중량부 미만을 혼합하는 경우에는 조성물의 점도가 과도하게 높아져 도포 작업이 어렵게 되고, 우레탄수지 100중량부 대비 300중량부를 초과하는 경우에는 점도가 낮아져서 도포를 한 조성물이 흘러내리는 문제가 발생할 수 있으므로, 우레탄수지 100중량부 대비 100~300중량부를 혼합하는 것이 바람직하다.
The methyl acetate (CH 3 COOCH 3 ) is a colorless solvent having excellent solubility with water and other organic solvents and having a fruit flavor, and is used as a solvent for a lacquer or paint remover due to its excellent solubility. Methyl acetate is safe enough to be used as a nail polish remover and has a boiling point of 57 ° C, thus accelerating the evaporation rate of the solvent. When the amount of the methyl acetate is less than 100 parts by weight based on 100 parts by weight of the urethane resin, the viscosity of the composition is excessively high and the coating operation becomes difficult. When the amount exceeds 300 parts by weight based on 100 parts by weight of the urethane resin, It is preferable to mix 100 to 300 parts by weight with respect to 100 parts by weight of the urethane resin.
상기 에폭시화합물은 부착성이 우수할 뿐만 아니라, 다양한 화학약품 및 용매에 대한 내구성이 뛰어나다. 이러한 특성들로 인해 상기 에폭시화합물은 해양, 항공기, 건축 등의 분야에서 금속, 알루미늄, 아연도금, 목재 및 콘크리트의 보수, 마감제, 보호 코팅 및 장식코팅을 위한 재료로 활용된다. 본 발명에서는 상기 우레탄수지의 수산기에 반응하는 작용기를 갖고, 수평균분자량이 2,500~6,500인 것을 적용할 수 있으며, 상기 우레탄수지 100중량부 대비 20~30중량부를 혼합함으로써 상기 우레탄수지의 경화 중 발포현상을 저감시키며 조성물의 코팅성능(접착력)을 향상시킨다.
The epoxy compound is not only excellent in adhesiveness but also excellent in durability against various chemicals and solvents. Due to these properties, the epoxy compounds are used as materials for repair, finishing, protective coatings and decorative coatings of metals, aluminum, zinc plating, wood and concrete in the fields of marine, aircraft, and construction. In the present invention, it is possible to use the urethane resin having a functional group reactive to hydroxyl groups of the urethane resin and having a number average molecular weight of 2,500 to 6,500. By mixing 20 to 30 parts by weight of the urethane resin with respect to 100 parts by weight of the urethane resin, And the coating performance (adhesion) of the composition is improved.
상기 실란화합물은 상기 우레탄수지 100중량부 대비 10~20중량부 혼합된다. 실란은 유기재료와 결합하는 유기작용기 및 무기재료와 반응하는 가수분해성기를 가지고 있어 양자를 결합시키는 역할을 한다. 즉, 실란화합물이 커플링제로 작용하여 이중 유기-무기 반응성을 통해 공유결합을 형성함으로써 조성물의 점착성을 강화시키고, 조성물 경화 후의 기계적 강도, 내수성 등을 향상시킨다.
The silane compound is mixed in an amount of 10 to 20 parts by weight based on 100 parts by weight of the urethane resin. The silane has a hydrolyzable group that reacts with an organic functional group and an inorganic material that bind to the organic material, thereby binding the both. That is, the silane compound functions as a coupling agent to form a covalent bond through dual organic-inorganic reactivity, thereby enhancing the tackiness of the composition and improving the mechanical strength and water resistance after curing the composition.

In the present invention, the silane compound obtained by treating an alkoxysilane with an acid at a temperature of 90 to 100 ° C and hydrolyzing the alkoxysilane can be applied. Generally, the alkoxysilane is hydrolyzed by water. In the present invention, acid treatment is performed for chemical hydrolysis which breaks the bond of alkoxysilane. As the acid treatment, an acid such as sulfuric acid, hydrochloric acid, hydrofluoric acid, boric acid, borax, phosphoric acid, sodium phosphate, sodium chloride, zinc oxide and the like can be used.

The polybutene is mixed with 5 to 10 parts by weight based on 100 parts by weight of the urethane resin, thereby improving the dispersibility and moisture resistance while improving the adhesion of the composition. The optimum viscosity of the polybutene used in the present invention is 2200 to 2400 mPa-s.
폴리머릭 엠디아이(polymeric MDI)는 이소시안네이트(-NCO)기를 가지고 있으며, 상기 우레탄수지 100중량부 대비 1 ∼ 5중량부 혼합되며, 이에 따라 조성물의 경화강도와 접착력을 증대시킨다.
