[Industrial Application Field] The present invention relates to a method for adhesion of flame-retardant wood, and the present invention relates to a method for adhesion processing of flame-retardant wood. This allows adhesive properties to be developed. [Prior Art] Adhesives commonly used for bonding wood include vinyl acetate adhesives, urea adhesives, α-cyanoacrylate adhesives, and resorcinol adhesives. These adhesives are applied to wood and then compressed or heated.
They dry and harden, or harden through condensation or polymerization reactions, and both are widely used as they can exhibit high adhesive properties when bonding wood. [Problems to be Solved by the Invention] However, although the above adhesives are suitable for adhering ordinary wood, they are not suitable for adhering flame-retardant wood. That is, since flame retardant wood is impregnated with a large amount of flame retardant, these adhesives have not been able to ensure high adhesiveness. Furthermore, even if the adhesive is bonded, there is a problem that the adhesive may peel off during combustion. Therefore, the present invention aims to solve these problems and provide an adhesive processing method that can firmly adhere flame-retardant wood. [Means for Solving the Problems] The present invention provides wood of the Araucaceae family with dicyandiamide, phosphoric acid, boric acid, guanylurea phosphate,
The solution is to use either a water-based polymeric isocyanate adhesive or an acrylic resin adhesive when adhering flame-retardant wood impregnated with a guanylurea phosphoric acid-boric acid product. It was used as a means. The present invention will be explained in detail below. The flame-retardant wood used in the present invention is a wood of the Araucaceae family, dicyandiamide, phosphoric acid, boric acid, and guanylurea phosphate, which is a partial reaction product of these and water.
All boric acid products are impregnated. Here, Araucaria is a general term for wood belonging to the Araucaceae family, such as agathis and almaciga.
Agathis is particularly preferred since it can contain a large amount of flame retardant and exhibit high flame retardancy. The partial reaction product of dicyandiamide, phosphoric acid, boric acid and water is a flame retardant described in JP-A-57-70178. This product is mainly composed of guanylurea phosphate produced by the reaction of dicyandiamide and phosphoric acid, the guanylurea phosphate-boric acid product produced when this guanylurea phosphate reacts with boric acid, and the unreacted guanylurea phosphate-boric acid product. It contains dicyandiamide, phosphoric acid, boric acid, etc., and as an example, it is prepared as an aqueous solution with a concentration of 20% by weight, but the concentration is not limited to this. These flame retardants can be impregnated by a well-known method such as vacuum impregnation or pressure impregnation, as described in column 4 on page 5 of the above-mentioned Japanese Patent Application Laid-Open No. 57-70178. The dicyandiamide, phosphoric acid, boric acid, guanylurea phosphate, and guanylurea phosphate-boric acid products are impregnated in fixed amounts of 100 kg or more per 1 m 3 of wood in the wood of the Araucaceae family, and have particularly high flame retardancy. The construction of the Ministry of Construction Notification No.
It is preferable to impregnate 500 kg or more of the solution per 1 m 3 of wood, since it can achieve wood that exceeds the standard value of the "semi-noncombustible material" test specified in No. 1231 and can be impregnated evenly. If the solid content is less than 100 kg, the effect of improving the flame retardance of wood will not be sufficiently obtained, which is not preferable. This flame-retardant wood is bonded using either a water-based polymeric isocyanate adhesive or an acrylic resin adhesive. Water-based polymeric isocyanate adhesives include a curing agent and a main agent made of polyaddition prepolymers such as tolylene diisocyanate and diol prepolymers, diphenylmethane diisocyanate prepolymers, and triphenylmethane triisocyanate prepolymers. It is an emulsion type product that is used by blending and mixing in a dispersion medium such as water. This adhesive is cured by a crosslinking reaction that proceeds simultaneously with the evaporation of the dispersion medium by means such as compression or heat compression.
Additionally, additives such as plasticizers, fillers, thickeners, and the like may be added to this adhesive as necessary.
Phthalate esters, dibutyl adipate, etc. are used as plasticizers, colloidal silica, calcium carbonate, etc. are used as fillers, and various water-soluble polymers such as casein, methylcellulose, and polyvinyl alcohol are used as thickeners. is used. Further, an appropriate coloring agent may be added as necessary. In addition, acrylic resin adhesives are primer-type adhesive-curing types in which a primer applied to one side of the adhesive and a main agent applied to the other side cause a curing reaction on the adhesive surface, and are modified into methacrylate monomers. A main ingredient is a solution in which chlorosulfonated polyethylene rubber is dissolved as a material, an organic peroxide as a polymerization catalyst is added, and a primer is added as a redox catalyst reducing agent such as a reaction condensate of an aldehyde and a primary amine. It's summery.
The curing mechanism uses a redox catalyst system,
It is thought that a graft polymerization reaction between the methacrylate monomer and the modifying material, chlorosulfonated polyethylene rubber, is also used. The method of adhesion is not particularly limited, but for example,
After applying the above-mentioned adhesive to the adhesion surface of the flame-retardant wood using an appropriate method such as brushing or roll coating, attach another adherend to this adhesive-coated surface, and allow the adhesive to harden and adhere. . The adhesive may be cured by a conventional method such as normal pressing or heat pressing, and conditions may be selected as appropriate so that the adhesive is cured. For other adherends, the same material, flame-retardant wood, is often used, but depending on the purpose, iron, aluminum, glass,
It may be made of wood, hard plastic or any other foreign material. According to this adhesive processing method, even though the flame-retardant wood is impregnated with a large amount of flame-retardant material, it is possible to firmly bond the flame-retardant wood to itself or the flame-retardant wood to other adherends. Can be glued to. this is,
The above-mentioned water-based polymer isocyanate adhesive or acrylic resin adhesive has a property that does not cause curing failure with the flame retardant described in JP-A-57-70178, so it can be used for wood conduits, etc. The pores of the wood are filled with a large amount of this flame retardant, and the flame retardant is exposed on the surface of the wood, effectively acting on flame-retardant wood that is apparently non-porous. it is conceivable that. Furthermore, there is no occurrence of adhesion failure. Moreover, this adhesive has the advantage that high adhesion is maintained even during combustion, and the flame-retardant wood and other adherends do not separate.

用される。[Table] As is clear from Table 1, it was found that the flame-retardant wood of the example bonded by the bonding method of the present invention had high adhesive strength and did not peel off even during combustion. On the other hand, in the flame-retardant wood of the comparative example using adhesives other than water-based polymer isocyanate-based adhesives and acrylic resin-based adhesives, adhesive strength was low and peeling was observed during combustion. [Effects of the Invention] As explained above, the present invention provides wood of the Araucaceae family impregnated with all of dicyandiamide, phosphoric acid, boric acid, guanylurea phosphate, and guanylurea phosphate-boric acid product. This process uses either a water-based polymeric isocyanate adhesive or an acrylic resin adhesive to bond flame-retardant wood, so even if the wood is impregnated with a large amount of flame retardant, Regardless, flame-retardant wood pieces or flame-retardant wood pieces and other adherends can be bonded with extremely high adhesive strength. Furthermore, the inconvenience of peeling between pieces of wood during combustion is also eliminated. Moreover, according to this adhesive processing method, the unique appearance of the wood is not impaired, so the wood has a rich woody feel and a warm feel, and is suitably used for various building materials.
