급기야 2020년 현재 10,000동이 넘는 목조주택이 착공되고 있어 목조주택 1만 세대에 진입하였다. 이러한 집에 사용되는 구조재인 수평부재로서 대들보, 장선 등의 지간거리가 상당히 길어지는 경향이 있다. 기존의 구조용 목재로서는 그 지간거리를 버텨낼 수 있는 구조적 강도가 갖춰지지 않으면서 공학목재인 집성재 등의 사용이 많아지고 있는 현실이다. 이와 같이 목재의 건축내외장재 이용에 대한 관심이 점점 높아져 목재의 단점을 보완하는 기술과 그 내구성에 대한 기술개발이 관심을 받고 있는것이다. 그런데, 이와 같은 구조용 목재 또는 집성재, 합판 등은 목재로 이루어지는 기본 특성상 습기에 약하여 잘 썩고, 단열이나 화재에 취약하며 외부노출시 변색등의 문제점을 안고 있다. As interest in a carbon-neutral society has recently increased, interest in the possibility of using wood and the government's policy to promote wood use have been followed. The timber industry market is continuously expanding due to increased interest in housing. Looking at the recent trends in wooden construction, the number of new buildings in 2006 was 4,203 with a total floor area of 365,000.

Finally, as of 2020, more than 10,000 wooden houses are under construction, reaching 10,000 wooden houses. As a horizontal member, which is a structural material used in such a house, the distance between beams and joists tends to be considerably longer. It is a reality that the use of laminated wood, which is an engineered wood, is increasing as existing structural wood does not have structural strength that can withstand the distance between spans. As such, interest in the use of wood for interior and exterior construction materials is increasing, and technology to compensate for the disadvantages of wood and technology development for its durability are attracting attention. However, due to the basic characteristics of such structural wood, laminated wood, plywood, etc., they are vulnerable to moisture and rot easily, are vulnerable to insulation or fire, and have problems such as discoloration when exposed to the outside.

Timber harvested directly from standing trees contains a large amount of moisture equivalent to about 50% or more of dry weight, depending on the species, and when wood products are manufactured by processing timber harvested while standing trees, In the process of drying the moisture contained, the wood cell walls inside the wood shrink or expand, causing deformation of the wood product. make a product And in another way, chemical treatment agents are injected into the wood to improve the dimensional stability of the wood. However, such a method has disadvantages in that the cost of processing the drug is high and it is very difficult to replace the chemical solution.

Therefore, in order to compensate for these disadvantages, efforts have been made to compensate for the disadvantages of wood by applying functional paints such as fire resistance, antiseptic, flame retardant and weather resistance to the surface of wood or by pressurized injection after decompression. However, the wood coated with such a functional paint has a problem that the paint peels off over time, and in the case of using an injection device, the initial installation cost of the device is over 300 million won, which is a large burden and the chemical tank is excessively large ( 20 tons or more) has a disadvantage in that the functional treatment to be given to wood is not properly performed because it is difficult to replace.
