Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wood for stabilizing the dimensions of wood such as indoor pillars, building materials, doors, ceiling boards, etc. of buildings such as houses, outer fences of outdoor wooden products, outdoor signboards, etc. Dimension stabilization method.

[0002]

2. Description of the Related Art Conventionally, the interior surfaces of pillars, building materials, lintels, ceiling panels, etc. in buildings such as houses are mainly coated with a synthetic resin paint, and a paint such as urethane, lacquer or varnish is applied. I have.

[0003] In addition, in order to paint the surface of an exterior fence of an outdoor wooden product, an outdoor signboard, or the like, a color such as brown is used so as to be inconspicuous even if the wood is discolored. I am applying a synthetic resin paint.

Accordingly, in both the indoor and outdoor wood products, the surface of the wood is sealed with the paint, so that the wood cannot repeatedly breathe wet and dry, and is easily steamed by the retained moisture. Therefore,

(1) As time passes, the color of wood becomes muddy or yellow.

(2) In indoor wood products, the wood is vulnerable to moisture and drying, shortening the life of the wood.

(3) In the case of outdoor wood products, the paint is turned over due to the rain and direct sunlight, and the life of the wood is short.

[0008]

[Problems to be Solved by the Invention] Wood of buildings such as houses and wood of outdoor wood products are resistant to warping, disorder and cracking, and are resistant to moisture and drying. The purpose is to prevent wood decay, stabilize the dimensions of the wood, and make the wood usable longer and more beautifully.

[0009]

The present invention provides a method for stabilizing the size of wood by applying a synthetic resin paint mixed with a small amount of a water retaining agent to the surface of wood and utilizing the action of the water retaining agent in the synthetic resin paint layer. With the goal.

That is, a synthetic resin paint mixed with a small amount of a water retention agent is applied to the surface of wood, and the water retention agent mixed into the synthetic resin paint absorbs moisture and expands, or dries back to its original state. If the water retention agent flakes off after years of use, countless small holes are created in the surface paint of the wood, and the wood slowly dries by repeatedly breathing wet and dry through the small holes. Warping, crazy, which is a drawback of wood,
A small amount of water retention agent is mixed with the purpose of stopping cracking, damp-proof and dry-proof, hardly getting dirt, preventing discoloration and decay of the wood, stabilizing the dimensions of the wood, and using the wood beautifully and for a long time. This was achieved by applying a synthetic resin paint to the surface of wood.

[0011]

1 to 5 show an embodiment of the present invention. The structure of the embodiment will be described with reference to the drawings. Etc., or wood such as outdoor fences of outdoor wooden products, outdoor signboards, etc., one board or several boards were superimposed in a cross type in which the directions of their capillaries alternated and glued with a water-resistant adhesive It is a laminate.

(2) a synthetic resin paint layer formed on the surface of the wood (1), which retains a small amount of 5% or less, for example, 1%, of water-absorbent resin in the synthetic resin paint (3) such as urethane paint. Along with mixing the agent (4), an appropriate amount of a curing agent and a thinner are formed by, for example, once applying a paint obtained by mixing the curing agent 1 and the thinner 1 with a synthetic resin paint 2 with a brush. (5)
Are small holes formed in the synthetic resin paint layer (2) by the water retention agent (4) in the synthetic resin paint layer (2) peeling off.

The operation will be described. As shown in FIG. 1, most of the surface of the wood (1) is covered with the synthetic resin paint (3) and a part of the water retention agent (4) is scattered.

For this reason, rain directly hits the surface of an outdoor wooden product such as an outer fence, an outdoor gable of a house, or an entrance attic.
As shown in FIG. 2, the water retaining agent (4) in the synthetic resin paint layer (2) is used on a bathroom or a column in a room where the surface of the synthetic resin paint layer (2) is exposed to water directly on a surface or on a wet day such as a rainy day. ) Absorbs moisture and swells outward, while on a sunny day it dries and the water retention agent (4) returns to its original state as shown in FIG. 1, and the water retention agent (4) depends on the state of moisture. Repeats the function and acts as a waterproof.

On the other hand, rain is hit by an outdoor wooden product, water is hit in a bathroom of a house, a cloth is hung on a pillar or the like, and a water retention agent in a synthetic resin paint layer (2) is used after many years of use. When (4) peels off, a small hole (5) is formed where the water retention agent (4) in the synthetic resin paint layer (2) has peeled off as shown in FIGS.

By the way, although water has a strong force to penetrate, it also has a force to bead and solidify due to surface tension. On the other hand, since the hole (5) after the water retention agent (4) has peeled off is small, the water is small. It is hard to get into the hole (5).

The wood (1) dries slowly in the hole (5) by repeatedly breathing slightly wet and dry.

However, except for the small hole (5) on the surface of the wood (1), the synthetic resin paint (3) is coated and covered with the synthetic resin paint (3), so that the wood (1) wets and dries. Is extremely slow.

That is, as in the case of the low-temperature dehumidifying and drying method, which is a method of drying wood, the wood (1) dries slowly, and the wood (1) does not warp, break, or crack.

FIGS. 6 to 9 show another embodiment of the present invention. The constitution of the embodiment is such that a small amount of powder (6) made of synthetic resin or the like is mixed in the synthetic resin paint layer (2) in the above embodiment. It was done.

That is, a paint obtained by mixing a small amount of a water retention agent (4) and a powder (6) in a synthetic resin paint (3) is applied once to the surface of the wood (1) with a brush, and the surface of the wood (1) is coated. To form a synthetic resin paint layer (2a). Other signs are
The same parts as those in FIGS. 1 to 5 are shown.

In this structure, the operation is the same as in the above embodiment.

However, in this structure, even if the water retention agent (4) in the synthetic resin paint layer (2a) peels off due to long-term use or the like, the powder (6) remains due to the remaining powder (6).
Since the surface of the wood (1) does not become smooth and the roughness of the surface of the wood (1) does not change, there is no discomfort.

[0024]

The method for stabilizing the dimensions of wood according to the present invention has the following advantages.

(1) A synthetic resin paint mixed with a small amount of a water retention agent is applied to the wood surface. Therefore,

(A) While the water-retaining agent is present in the synthetic resin paint layer, the water-retaining agent expands on a rainy day or a wet day such as a rainy day while the water-retaining agent is present in the synthetic resin paint layer. The water retention agent dries and returns to its original state, and the water retention agent repeats the above operation depending on the weather conditions to provide a waterproof effect.

(B) If the surface of the synthetic resin paint layer is exposed to rain or water, is ragged, or if the water retainer in the synthetic resin paint layer has peeled off due to long-term use, the water retainer is used. It is difficult for water to enter the small hole that was formed at the place where it was peeled off. On the other hand, the surface of the wood is coated with synthetic resin paint except for the small holes, so that the small holes only wet and dry repeatedly and breathe. Does not appear.

(C) Since most of the surface of the wood is covered with the synthetic resin paint, the wood is not stained.

(D) Since the wood is dried slowly with small holes, the wood can be beautifully and long-lasting.

(2) Anyone can easily apply by brushing.

(3) If powder is mixed with a water retaining agent in a synthetic resin paint and the paint is applied to the surface of wood, the water retainer in the synthetic resin paint layer on the surface of the wood will peel off due to long-term use or the like. However, since the surface of the wood does not become slippery due to the remaining powder, the roughness of the wood surface does not change, so that there is no sense of incongruity and it is practically useful.
