  The present invention will be described in more detail below. In the present invention, in a wallpaper composed of a base layer and a surface layer (not shown), a deodorant, a water repellent resin compound, and a layered silicate mineral are fixed together with a penetrant on the upper side of the surface layer by a binder resin. A method for producing an antifouling deodorant wallpaper and an antifouling deodorant wallpaper.

  The base material layer is not particularly limited, and paper made of pulp or cellulose may be used, or a non-woven fabric or woven fabric made of synthetic fiber or natural fiber, or a plastic film may be used. The base material layer is affixed to walls such as concrete and wooden boards via an adhesive, but it is difficult to release moisture and easily generates mold. Is preferred. In general, adhesives often contain a volatile organic solvent, and VOC (volatile organic compounds) are generated from the adhesive itself during use. No adhesive is preferred.

  A surface layer is laminated on the upper side of the base material layer. The surface layer is preferably made of one or more thermoplastic resins selected from vinyl chloride resin, styrene resin, acrylic resin, and polyethylene resin. The surface layer is a layer located on the indoor space side when wallpaper is attached to the wall, to reinforce the base material layer, to give design, and to add a feeling of unevenness Often used is a foamed resin film embossed. The adhesion between the base material layer and the surface layer is preferably performed by thermocompression bonding. In general, a method using an adhesive is not preferable because a volatile organic solvent is often used for the adhesive, and VOC (volatile organic compound) is often generated. In the present invention, the method of heating and pressure-bonding a thermoplastic resin is preferable as a method of suppressing the generation of VOC (volatile organic compound).

  Although it does not specifically limit as a penetrating agent, A cationic surfactant, an anionic surfactant, a nonionic surfactant, etc. can be mentioned.

  Examples of the binder resin include acrylic resins, urethane resins, epoxy resins, and acrylic silicon resins. Of these, acrylic resins are preferable, and acrylic emulsions or water-soluble acrylic resins are preferably used.

Examples of the porous inorganic substance constituting the deodorant include one or more porous inorganic substances selected from silica gel, silicon oxide, activated carbon, diatomaceous earth, and zeolite. The specific surface area of the porous inorganic substance is preferably 400 to 900 m ² / g. If the specific surface area is too small, the contact area with the malodorous substance is reduced and the deodorizing ability is lowered. On the other hand, if the specific surface area is too large, too much amine compound is adsorbed, which is not preferable because it tends to discolor during heating after coating. The average particle diameter is preferably 5 nm to 20 μm, and the average pore diameter is preferably 0.1 to 10 nm. If the average pore diameter is too small, the specific surface area increases, but the amine compound hardly enters the pores, and the deodorizing ability decreases. When the average pore diameter is too large, the specific surface area decreases and the deodorizing ability decreases. The specific surface area can be measured by the BET method calculated from the nitrogen adsorption amount.

  Next, the amine compound constituting the deodorant is preferably one or more compounds selected from aliphatic polyamine compounds, aromatic polyamine compounds, and hydrazide compounds. Of these, hydrazine derivatives and the like are preferably used. Such an amine compound has a property of adsorbing and decomposing chemical substances such as formaldehyde, acetaldehyde, and acetic acid. Note that the solubility of such an amine compound in water is desirably 5 g / L or less at 25 ° C. If the solubility in water is within this range, it is possible to prevent the amine compound from dissolving and flowing out even if it contacts water during use. Examples of the hydrazine derivative include those obtained by reacting a hydrazine compound and a long-chain aliphatic compound, or those obtained by reacting a hydrazine compound and an aromatic compound.

  Among them, one or two compounds selected from the group consisting of hydrazine and semicarbazide, and one selected from the group consisting of monocarboxylic acids, dicarboxylic acids, aromatic monocarboxylic acids and aromatic dicarboxylic acids having 8 to 16 carbon atoms. Selected from the group consisting of reaction products with two or more compounds, one or two compounds selected from the group consisting of hydrazine and semicarbazide, and monoglycidyl derivatives and diglycidyl derivatives having 8 to 16 carbon atoms Reaction products with one or more compounds are preferred. By using such a hydrazine derivative, it is possible to secure a more excellent malodor removal function. Examples of the reaction product include sebacic acid dihydrazide, dotecannic acid dihydrazide, isophthalic acid dihydrazide, and the like, but are not particularly limited to these exemplified compounds.

  Next, as the metal oxide constituting the deodorant, one or more oxides selected from zinc, iron, silver, copper, aluminum, magnesium, manganese, nickel, cobalt, and titania are preferable. Of these, zinc oxide is preferable. Metal oxides have the property of decomposing chemical substances such as hydrogen sulfide, mercaptans, acetic acid, amines, and ammonia.

  As the water repellent resin compound, fluorine resin, silicon resin, and hydrocarbon resin are preferable. Among these, a fluorine resin is preferable. The water-repellent resin compound has a property of repelling dirt caused by coffee, soy sauce, aqueous magic, crayon, etc. and making it difficult to adhere.

  As the layered silicate mineral, bentonite, montmorillonite, hydelite and hectorite are preferable. Among these, bentonite is preferable. The layered silicate mineral has the property of facilitating removal of dirt caused by coffee, soy sauce, aqueous magic, crayon, etc. Furthermore, it has the property of adsorbing and reducing allergens.

  Moreover, it is preferable that the average particle diameter of an amine compound, a metal oxide, a porous inorganic substance, and the said layered silicate mineral is 5 nm-20 micrometers. When the particle size exceeds 20 μm, a rough feeling is developed, which is not preferable. In addition, it is difficult to technically produce a particle size of less than 5 nm, which is not preferable because it is not cost effective.

Next, the adhesion amount of the porous inorganic substance to the wallpaper is preferably 0.1 to 2.0 g / m ² . If it exceeds 2.0 g / m ² , the graininess will be manifested and whitening will occur. If it is less than 0.1 g / m ² , the deodorizing effect is decreased, which is not preferable. The amount of the amine compound fixed to the wallpaper is preferably 0.1 to 1.0 g / m ² . If it exceeds 1.0 g / m ² , a rough feeling will be developed and whitening will occur. If it is less than 0.1 g / m ² , the deodorizing effect is decreased, which is not preferable. The amount of metal oxide fixed to the wallpaper is preferably 0.1 to 2.0 g / m ² . If it exceeds 2.0 g / m ² , the graininess will be manifested and whitening will occur. If it is less than 0.1 g / m ² , the deodorizing effect is decreased, which is not preferable. The amount of the water-repellent resin compound fixed to the wallpaper is preferably 0.2 to 3.0 g / m ² . Even if it exceeds 3.0 g / m ² , an effect commensurate with an increase in the amount of fixing cannot be obtained. When it is less than 0.2 g / m ² , the antifouling effect is decreased, which is not preferable. The fixed amount of the layered silicate mineral to the wallpaper is preferably 1.0 to 5.0 g / m ² . If it exceeds 5.0 g / m ² , a rough feeling will appear and whitening will occur. When it is less than 1.0 g / m ² , the antifouling effect is decreased, which is not preferable.

  Although the method of apply | coating a deodorizer, a water repellent resin compound, and a layered silicate mineral to wallpaper is not specifically limited, A coating method can be illustrated. For example, gravure roll processing, spray processing, roll coater processing, jet printing processing, transfer printing processing, screen printing processing and the like can be mentioned. The surface layer is coated with a mixture of binder resin, penetrant, deodorant, water repellent resin compound and layered silicate mineral on the wallpaper, and then dried, so that the adsorbent and deodorizing decomposition together with the binder resin on the surface layer The agent, the water repellent resin compound, and the layered silicate mineral are firmly fixed. The coating method is a suitable method as a method capable of remarkably improving productivity and controlling the fixing amount with high accuracy.

  The coating method is useful as a processing method capable of adhering the binder resin in a mesh form, rather than bonding the binder resin as a film on the surface layer. This is because the binder resin does not adhere to the entire surface as a layer, but leaves a space on the surface layer as a part that provides functionalities other than deodorization, antifouling, and allergen reduction, by adhering in a mesh shape. For example, flame retardancy can be further imparted.
