。The conventional method for adhering wood to gypsum board is to apply pressure to the moisture-proof treated surface of gypsum board by pressing wood coated with a kerosene-based antiseptic and insect repellent through a layer of vinyl acetate-based adhesive. [Problems to be Solved by the Invention] However, in such a method, the moisture-proof treated surface of the gypsum board and the rot-proof and insect-proof treated surface of the wood and the vinyl acetate adhesive have poor wettability, so that press curing is difficult. The problem is that you have to spend more time on it. Therefore, it is possible to use an adhesive (ethylene-vinyl acetate type) that has good wettability with the adherend, but the cost is 230 yen/kg compared to 125 yen/kg for vinyl acetate-based adhesive. There was a problem in that it was disadvantageous in terms of cost. An object of the present invention is to provide a method for bonding wood to gypsum board that can shorten press curing time even when using a vinyl acetate adhesive and provides sufficient adhesive strength. (Means for Solving the Problem) The method for adhering wood to a gypsum board of the present invention is a method for adhering wood to a gypsum board by pressurizing and adhering wood that has been treated with antiseptic and insect repellent to the gypsum board via an adhesive layer. , a large number of small holes are provided on the adhesive surface of the wood. (Function) According to this invention, as shown in FIG. 1, many small holes 2 are provided on the adhesive surface of the wood 1, so that the adhesive enters the small holes 2 and the surface area of the adhesive layer 3 becomes large. It can be dried quickly and the curing time is shortened. In addition, the adhesive enters the small holes and the adhesive layer engages with the wood, increasing the adhesive strength. [Example] (1) Gypsum board; Vinylidene chloride (2) Wood; ■ The dimensions of the test piece were 20 m (vertical dimension) x 40 a * (horizontal dimension) x lOw (thickness dimension). ■ Kerosene was applied to the wood as a preservative and insect repellent treatment. A type of preservative and insect repellent was applied. ■ A small hole was made on the preservative and insect repellent treated surface of the wood. The diameter of the small hole was 0.5 to 1 [llff1, and the depth of the small hole was 5
The number of holes and holes was 5 or more per lc-. (3) Adhesion/pressing: Apply a undiluted solution of vinyl acetate adhesive to the hole-forming surface of the wood (applying amount is 180 g/rrr), then adhere the wood to the vinylidene chloride coated surface of the plasterboard and press curing. (Press pressure was 1.0 kg/cj). The robe shows a comparison of the adhesive strength between this example and the conventional example. Table As is clear from this table, the press curing time is 1
The time was shortened from more than 2 hours to 6 hours, and the adhesive strength was also increased. [Effects of the Invention] According to the method of adhering wood to gypsum board of the present invention, the adhesive layer dries quickly and press curing time is shortened. Additionally, the adhesive force is increased by the adhesive entering the small holes and engaging the adhesive layer with the wood. Furthermore, less press curing space is required and running costs can be reduced.
