Description

TWIST PROTECTING AND LIFE EXTENDING OF WOOD DECK}

The present invention relates to a method of preventing warping and extending the life of a wooden deck installed on the floor of a terrace or a walkway in a park, and more particularly, a shape deformation such as cracking or warping occurs due to shrinkage, expansion, and decay of the wooden deck. The present invention relates to a method of preventing warping and extending the life of wood decks to prevent moisture evaporation and increase wear resistance.

Wood decks have excellent processing characteristics and aesthetics, but as time goes by the cracking and warping of wood occurs, the deformation occurs in the wood, which causes a problem that the life of the wood structure consisting of the wood deck is shortened.

     In other words, the wood deck receives a lot of internal and external moisture, rain, and sunlight directly, causing temperature differences, and bending, deformation, shrinkage, splitting, etc. of wood in the process of volatilizing water or absorbing moisture from the outside. There is a problem that occurs.

     Wood structures inevitably have areas of external and high exposure and areas that are not or moderately exposed. In addition, since there is a difference between high and low humidity of the surrounding environment, a change in moisture content that affects the durability of the wood deck occurs in the contact surface with the external environment such as ultraviolet rays.

     Moisture content is a major determinant of the durability of the wood deck, which is both a fatal disadvantage and an advantage. In wood, moisture content (MC) is the percentage of water in wood, and all properties such as strength and shrinkage of wood vary with water content. If the wood deck is a tree, it is divided into Bukyangjae (mainly conifer) and Namyangjae (mainly hardwood, hardwood), and the water content after processing of the wood deck decreases with time, and the surface inside the wood deck The contraction of wood decks by evaporation causes cracking and warping, which inevitably deforms the wood deck structure, which shortens the life of the whole structure.

     In order to prevent the shape deformation of the wood and to extend the life of the wood deck, the contact surface with the external environment is minimized to reduce the moisture content change that influences the durability of the wood deck, to suppress excessive water evaporation of the wood, to evaporate moisture, The use of wood decks that are machined to achieve hygroscopic balance can extend their life.

     In general, the preservative treatment of wood, oil stand, etc. are made to release moisture inside the wood to the outside but to prevent the moisture from being absorbed upside down. The main purpose is to prevent the growth of fungi, etc., which enters the moisture of the wood. In this case, if the moisture enters the cracks, the thickening of the wood will proceed unless it is treated with sufficient depth of preservation.

     The structure of wood is to prevent the deformation and decay of wood by drying and preserving the wood in advance.The drying process of wood is wood drying, atmospheric drying, and it is pressurized with antiseptic chemicals. In principle, it should be used as it is, or treated with minimal environmentally friendly chemicals (eg lacquer, enamel resin). At this time, in order to reduce the internal moisture (water content) and prevent deformation as much as possible, the preservatives are injected by maintaining the vacuum state in this process, but it is effective when the wood is soft. (Usually softwood), when the material of the wood is dense or the wood itself is not dried, the knot part of the wood does not reach the chemicals, and in many cases, it does not have an antiseptic effect as expected performance. In addition, the dissolution of antiseptic drugs is a social problem, and CCA antiseptics, known as strong toxicity, are regulated for use, and ACQ and CUAZ preservatives commonly contain copper elements, which are aquatic. Not a lot of CCA, but not a good impact on the ecosystem. Boric acid-based antiseptics do not have strong antiseptic properties, toxicity, etc., but there is a problem that it is eluted easily due to rain, snow, etc., so that the preservative properties of wood cannot be maintained. Although water treatment is used on wood, the case of direct exposure is not economically effective.

The present invention processes the surface of the wooden deck to minimize the contact area with the external exposure environment, and also by applying a coating solution containing alumina or titanium dioxide to the surface of the wooden deck, to suppress excessive moisture evaporation, wear resistance It is an object of the present invention to provide a method of preventing warping and extending the life of a wooden deck that is not warped or warped and which has a long life.

'Shape cross section is formed to be repeated in the longitudinal direction, characterized in that to minimize the external exposure surface area of the wood deck.

The present invention will be described in detail with reference to the accompanying drawings. 1 is a cross-sectional view of a conventional wooden deck, Figure 2 is a cross-sectional view of the wood deck of the present invention, Figure 3 is a cross-sectional surface coating of the present invention wood deck.

     In the case of wood decks installed outdoors, the area of contact with the external environment is proportional to the area of the surface exposed to the outside, thus reducing the change in moisture content that influences the durability of the wood deck when processed to minimize the exposed area. It can be.

     Therefore, the wood deck according to the present invention is repeated in the longitudinal direction on the upper surface is formed with a valley and ridges, the valley is a v-shaped groove in the cross-section and the ridge is the top of the plane.

     In an embodiment, the wooden deck bottom plate is provided with a support at the bottom, and the wood is arranged side by side at a predetermined interval on the top of the support and connects the sides between each other to construct the bottom plate. When constructing the wooden deck deck, the surface area of the deck top is proportional to the top length.

     Wood installed on the deck floor plate is repeated in the longitudinal direction on the top surface is formed. 1 to 3, the plurality of grooves represent the valleys. Wood deck according to the present invention can be seen that the exposed area is smaller than the conventional wood deck of FIG.

     This difference in exposure area is more likely to be affected by wood decks being installed in wetlands or in wet or dry weather. When air dries, the moisture inside the wood is released to the outside and the moisture content changes. The evaporation rate of water, which changes the water content, which influences the durability of the wood deck, is more likely to evaporate as the surface area in contact with air is larger.

     Therefore, the processing is performed to minimize the surface area of the wood, especially in places where the bottom plate is exposed to direct sunlight. As such, the present invention extends the life by stabilizing the shape of the wood by reducing the change in moisture content by processing the wood deck to minimize the contact area with the external environment.

     In addition, the water repellent, which prevents the penetration of water into the wood, and preservatives used to enhance the antiseptic effect and the insect repellent finish, such as external oil stains, prevents the wood from being deformed and deteriorated and extends the life of the wood deck. The lower the degree of infiltration of the preservative, the richer it is.

     The cross-sectional shape of the wood in the figure is closely related to the infiltration of the antiseptic solution. Conventional wood cross-sectional shape according to Figure 1 has a circular to octagonal shape in the upper portion compared to the cross-sectional shape of the wood according to the present invention, the lower end of the groove is narrower and the upper part is more angular.

     In this conventional type, preservatives and finishes do not penetrate deeply into the wood and are not treated with sufficient preservative depth when the preservative is to be treated.

     However, the wood according to the present invention has a flat upper end and the shape of the groove is simpler and wider than that of the conventional type, so that the preservative can be evenly penetrated deeply into and out of the wood.

     Although the landscaping structural material installed outdoors is mainly treated by a pressurized antiseptic method, it is often embalmed by a coating or spraying method. At this time, paint using a paint brush or roller or spray using a sprayer. When using a brush or a sprayer to finish the structure, such as treating the re-processed part of the pre-coated wood, or applying a surface of the wood in an unbalanced area such as top, bottom, left and right after the construction of the wood deck, The lower part of the narrow and the upper part is angular or rounded parts are difficult to paint evenly deep. However, the wood deck of the present invention is processed so that the preservative is easy to paint deep inside and outside the wood.

     Preservatives can prevent wood from releasing moisture and prevent the access of bacteria or fungi, which can prolong wood deck life by preventing the wood from decaying. The present invention is due to the structure of the wood preservative can penetrate deeply into the wood to improve the durability to extend the life.

     In addition, the present invention is a warp-proof and life-long wood deck to increase the wear resistance by using a wood preservative added to the phosphate-based inorganic alumina, or titanium dioxide and other inorganic systems.

     Wood preservatives are classified into inorganic chemicals and organic chemicals and include water-soluble preservatives, oil-based preservatives, and oil-soluble preservatives.

As a water-soluble preservative, simple metal salts, such as mercury chloride, zinc chloride, and copper sulfate, are dissolved in water, but such preservatives have the drawback that the preservatives are leached from wood when used in a humid place.

Oil-soluble preservatives include organic iodine compound (IPBC) and organic iodine phosphorus compound (IPBCP). The organic iodine phosphorus compound system (IPBCP), which is a phosphate-based preservative, is mainly a wood preservative member used indoors and is basically nontoxic, and has little elution due to surface hardening properties.

     The present invention enhances wear resistance by adding alumina or titanium dioxide, which is an inorganic substance, to the phosphate preservative. Titanium dioxide (TiO 2) is a chemically and physically stable material that is harmless to the environment and the human body, and is used as a pigment and of course an abrasion resistance enhancer. Alumina is harmless to the human body, light and durable.

     Phosphate-based preservatives are basically non-toxic and have low elution due to surface hardening properties, impart flame retardant performance of wood, and are more resistant to wear than other preservatives, but are insufficient for use in mechanical friction such as walking. The addition of alumina or titanium dioxide and other inorganic systems enhances the wear resistance and air-blocking performance, thereby blocking the wood's water-volatile properties, which can extend the lifespan of wood.

     The mixing ratio of alumina or titanium dioxide is 95% to 97% by weight of phosphate, and 3% to 5% of alumina or titanium dioxide is appropriate by weight. When the ratio of alumina or titanium dioxide is low, the above abrasion resistance and air barrier increase efficiency cannot be achieved. When the ratio of alumina or titanium dioxide is high, the manufacturing cost is high and viscosity becomes difficult to work.

     And to coat the surface of the wooden deck 10, the coating is applied to the extent that the coating liquid is enough to remain in the uneven groove of the surface of the wooden deck at least. That is, even if a part of the coating liquid having abrasion resistance penetrates into the wood, a considerable amount of liquid remains in the uneven groove of the wood deck to form a coating layer, and the formed coating layer suppresses excessive moisture evaporation of the wood deck 10 and improves wear resistance. It doesn't twist or bend and lasts a long time.
