Abstract
Description
본 발명은 친환경 레진(이하 “송진”이라 한다.) 함침 목재의 제조방법 및 이 방법으로 제조된 송진 함침 목재에 관한 것이다. The present invention relates to a method for manufacturing eco-friendly resin (hereinafter referred to as “resin”) impregnated wood and to rosin-impregnated wood manufactured by this method.
근래 들어, 경제 성장 및 이에 따르는 생활수준의 향상으로 웰빙 열풍이 강하게 불고 있다. 이러한 웰빙 열풍은 주거환경에 대한 웰빙 추세를 형성하고 있으며, 이러한 추세는 천연 목재를 내, 외장재로 사용한 주택 및 가구에 대한 관심으로 이어지고 있다.In recent years, the well-being craze is blowing strongly due to economic growth and the accompanying improvement in living standards. This well-being craze is forming a well-being trend for the residential environment, and this trend is leading to interest in houses and furniture using natural wood as interior and exterior materials.
그러나, 건조된 천연 목재를 사용한 주택 등은 목재의 내부 보존제의 감소, 외부 부후균의 침투로 인한 부식 등으로 피해가 증가하여 내구성에 큰 약점을 갖는 것으로 알려져 있다. 특히 오래되어 보존제가 감소된 목재에는 틈이 많이 생기고, 수분 유입이 원활하게 이루어져 목재의 부패 환경이 조성되기 쉽고, 보존제성분이 토양으로 용탈되어 토양환경을 오염시키는 문제를 야기시키고 있다. 이러한 문제를 해결하기 위하여, 목재의 흡수성 및 부식성 개선 등이 이루어진다. 예를 들어, 송진 도포, 항균처리, 훈증법, 살충제 도포법 등의 방법이 사용되고 있다. 그러나 이러한 방법은 일시적으로 문제를 해결해 주나, 근본적인 해결에는 미흡한 측면이 있다. However, it is known that houses using dried natural wood have a significant weakness in durability due to increased damage due to a decrease in the internal preservative of the wood and corrosion due to the penetration of external decay bacteria. In particular, old wood with reduced preservatives has many cracks, and water inflows smoothly to create a decomposing environment for wood, and preservatives are leached into the soil, thereby contaminating the soil environment. In order to solve this problem, the absorption and corrosion of wood are improved. For example, methods such as rosin application, antibacterial treatment, fumigation method, and insecticide application method are used. However, these methods temporarily solve the problem, but have insufficient aspects to fundamentally solve the problem.
한편, 목재의 내구성을 강화하여 사용 수명을 늘리기 위하여, 목재의 표면 강화, 방부, 방습, 방충 처리 등을 일괄적으로 수행하는 목재 내구성 강화 방법도 다양하게 소개되고 있다. 이러한 방법으로는 예를 들어, 실용신안등록 제20- 0333178호(옻칠을 이용한 가구용 목재), 특허공개 제10-2010-0138320호(도장용 도료조성물), 특허공개 제10- 2011-0117309호(천연재료로 구성된 흙벽 또는 목재 방수용 조성물) 등이 알려져 있다. 그러나, 이러한 방법들은 비용이 너무 많이 소요되거나, 천연목재의 특성을 제대로 살리기 어렵거나, 대량생산에 적합하지 않다는 단점을 갖는다. On the other hand, in order to enhance the durability of the wood to increase the service life, various methods for strengthening the wood durability have been introduced in which the surface reinforcement, antiseptic, moisture-proof, insect-proof treatment, etc. of the wood are collectively performed. In this method, for example, Utility Model Registration No. 20-0333178 (wood for furniture using lacquer), Patent Publication No. 10-2010-0138320 (Paint composition for painting), Patent Publication No. 10-2011-0117309 ( Soil wall or wood waterproofing composition made of natural materials) and the like are known. However, these methods have disadvantages in that cost is too high, it is difficult to properly utilize the characteristics of natural wood, or is not suitable for mass production.
특히, 종래기술에서는 목재에 대해 쉽게 도막을 형성하면서 강도 및 광택을 향상시키는데 탁월하며, 살균성 강한 성질을 가지는 송진을 목재 표면에 도포하는 방법이 많이 시도되고 있다. 그러나, 이러한 방법은 송진의 높은 점성으로 인해 도포가 어려울 뿐만 아니라, 사용 시 도막이 파괴되면 쉽게 부식되는 결정적인 단점을 갖는다.In particular, in the prior art, many attempts have been made to apply rosin, which is excellent in improving strength and gloss while easily forming a coating film on wood, and has strong bactericidal properties, on the surface of the wood. However, this method has a decisive disadvantage in that it is difficult to apply due to the high viscosity of rosin, and is easily corroded if the coating film is destroyed during use.
본 발명은 종래기술의 상기와 같은 문제를 해소하기 위하여 안출된 것으로서, 송진을 액상으로 특수가공 처리하여 목재에 진공함침시켜 목재의 강도, 내습성, 내부식성을 개선시킴으로써, 목재의 수명을 크게 증가시키는 송진 함침 목재의 제조방법 및 이 방법으로 제조된 송진 함침 목재를 제공하는 것을 목적으로 한다.The present invention has been devised to solve the above problems of the prior art, and by special processing of rosin in a liquid phase and vacuum impregnating the wood to improve the strength, moisture resistance, and corrosion resistance of wood, greatly increase the lifespan of wood An object of the present invention is to provide a method for manufacturing rosin-impregnated wood and rosin-impregnated wood manufactured by this method.

이하에서 본 발명에 대하여 자세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명은 (a) 분쇄된 송진 17 내지 60 중량%, 에탄올 35 내지 60 중량%, 식용 빙초산 0.2 내지 3 중량%, 및 식물성오일 3 내지 20 중량%를 혼합하여 함침용액을 제조하는 단계; (b) 상기 함침용액을 색상이 황색으로 변할 때가지 숙성시키는 단계; (c) 상기 함침용액을 밀봉용기에 넣고, 목재를 침지시킨 후, 밀봉시키는 단계; 및 (d) 상기 밀봉용기 내부 환경을 진공 상태와 대기 상태로 번갈아 가며 형성하는 단계;를 포함하는 송진 함침 목재의 제조방법에 관한 것이다.The present invention comprises the steps of (a) mixing 17 to 60% by weight of pulverized rosin, 35 to 60% by weight of ethanol, 0.2 to 3% by weight of edible glacial acetic acid, and 3 to 20% by weight of vegetable oil to prepare an impregnation solution; (b) aging the impregnating solution until the color changes to yellow; (c) putting the impregnating solution in a sealed container, immersing the wood, and sealing; and (d) alternately forming the internal environment of the sealed container in a vacuum state and an atmospheric state;

상기 (c) 단계에서 밀봉용기는 내압용기일 수 있다. 즉, 내부를 진공 상태로 유지하거나, 가압하여 대기압보다 높은 압력을 인가하더라도 견딜 수 있는 용기일 수 있다.The sealed container in step (c) may be a pressure-resistant container. That is, it may be a container that can withstand even if the inside is maintained in a vacuum state or pressurized to apply a pressure higher than atmospheric pressure.
상기 (c) 단계에서 목재는 수분함량이 12 내지 19 중량%인 것이 바람직하게 사용될 수 있다. 상기 목재로는 특별히 한정되는 것은 아니나, 소나무, 편백나무, 미루나무 등일 수 있다.In step (c), the wood may preferably have a moisture content of 12 to 19 wt%. The wood is not particularly limited, but may be pine, cypress, cottonwood, or the like.
