TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a deodorant composition for deodorizing an aldehyde odor and a wood material from which an aldehyde odor is deodorized.
[0002]
[Prior art]
Formaldehyde-based wood adhesives are known as adhesives for plywood, particle board, fiber board (MDF), etc., which are used as building materials, interior materials and the like, or as materials for the building materials. Since the adhesive has excellent adhesiveness and workability, it is frequently used in the above-mentioned applications. However, in houses using the building materials, interior materials, and the like, there is a problem in that so-called sick house syndrome occurs, which causes occupants to feel uncomfortable due to formaldehyde emitted from the adhesive.
[0003]
Conventionally, in order to solve the above problem, a deodorant is applied to the building material, the interior material, and the like. As the deodorant, for example, a deodorant composition containing a hydrazide compound and a polyoxyethylene alkyl ether type nonionic surfactant is known.
[0004]
The deodorant composition uses a polyoxyethylene alkyl ether type nonionic surfactant represented by the general formula RO (CH ₂ CH ₂ O) _n H, wherein R is the number of carbon atoms in the general formula. It is a straight-chain or branched-chain alkyl group of 8 to 18, and n is preferably an integer of 2 to 4 (for example, see Patent Document 1).
[0005]
However, the deodorant composition is hardly absorbed by the wood material, and when the surface of the wood material treated with such a deodorant composition is ground, the deodorizing performance against aldehyde is reduced. There is a disadvantage of doing so.
[0006]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 2000-300652
[Problems to be solved by the invention]
An object of the present invention is to provide a deodorant composition which solves such inconveniences, has excellent deodorizing performance against aldehydes, and is easily absorbed by wood materials.
[0008]
Another object of the present invention is to provide a wood material capable of maintaining excellent deodorizing performance against aldehyde even when the surface is ground.
[0009]
[Means for Solving the Problems]
In order to achieve this object, the deodorant composition of the present invention comprises a hydrazide compound and a general formula RO (CH ₂ CH ₂ O) _n H ( _where R is an aliphatic group having 8 to 18 carbon atoms). And n is an integer of 5 to 15).
[0010]
According to the deodorant composition of the present invention, in the nonionic surfactant represented by the general formula, n is an integer of 5 to 15, and the nonionic surfactant used in the conventional deodorant composition The molecular chain is longer than the agent. Therefore, excellent affinity with the wood material is obtained, and the wood material is easily absorbed by the wood material.
[0011]
When the number of carbon atoms of the aliphatic group represented by R in the above general formula is less than 8, no action as a surfactant is obtained. If the aliphatic group has more than 18 carbon atoms, it becomes difficult to form a surfactant itself.
[0012]
On the other hand, when the number of polyoxyethylene groups represented by n in the general formula is less than 5 or the number of polyoxyethylene groups exceeds 15, the deodorant composition absorbs the wood material. In addition, the aldehyde cannot be sufficiently deodorized.
[0013]
As the nonionic surfactant, those in which R in the general formula is a linear or branched alkyl group having 8 to 18 carbon atoms, or CH ₃ (CH ₂ ) ₇ CHＣＨCH (CH ₂ ) it can be used to a ₇ CO- represented by an oleyl group (also referred to as oleoyl group).
[0014]
The deodorant composition of the present invention preferably contains 0.1 to 20% by weight of the hydrazide compound and 0.1 to 5% by weight of the nonionic surfactant, based on the total amount. When the hydrazide compound is less than 0.1% by weight based on the total amount of the deodorant composition and the nonionic surfactant is less than 0.1% by weight based on the total amount of the deodorant composition, On the other hand, sufficient deodorizing performance cannot be obtained. On the other hand, when the hydrazide compound exceeds 20% by weight with respect to the total amount of the deodorant composition and the nonionic surfactant exceeds 5% by weight with respect to the total amount of the deodorant composition, the hydrazide compound And non-ionic surfactants are difficult to mix, and sufficient performances such as solubility and secondary adhesiveness cannot be obtained.
[0015]
Further, the deodorant composition of the present invention further comprises at least one compound selected from the group consisting of metal halides, metal nitrates, metal sulfates, metal sulfites, and metal hydroxides. . The deodorant composition of the present invention can obtain more excellent deodorant performance against aldehyde by containing the compound. In the compound, the term "metal" includes an alkaline earth metal.
[0016]
In addition, the woody material of the present invention comprises a hydrazide compound and a general formula RO (CH ₂ CH ₂ O) _n H (wherein R is an aliphatic group having 8 to 18 carbon atoms, and n is an integer of 5 to 15) Wherein the composition is characterized by being coated or impregnated with a deodorant composition containing a nonionic surfactant represented by the formula:
[0017]
As described above, the deodorant composition of the present invention is excellent in deodorizing performance for aldehydes, but is easily absorbed by wood materials. Therefore, when the deodorant composition of the present invention is applied or impregnated to a wooden material, it penetrates deeply into the wooden material. Therefore, the woody material of the present invention can maintain excellent deodorizing performance against aldehyde for a long time.
