Description
本発明はパーティクルボード、ＭＤＦ（中密度繊維板）等の木質ボード、その他の建材中に添加してその撥水性を向上させる撥水性組成物の改良に関する。 The present invention relates to an improvement in a water-repellent composition that is added to a wooden board such as particle board, MDF (medium density fiberboard), or other building materials to improve its water repellency.
一般的に、木質ボードにはその耐水性を確保するため撥水性組成物が添加されている。かかる撥水性組成物として、例えば特許文献１や特許文献２にはパラフィンワックス、石油樹脂、アスファルト、シリコーン系樹脂、フッ素系樹脂等が例示されている。中でも、価格の面からパラフィンワックスが選択される場合が多い。 In general, a water repellent composition is added to a wooden board to ensure its water resistance. As such water-repellent compositions, for example, Patent Document 1 and Patent Document 2 illustrate paraffin wax, petroleum resin, asphalt, silicone resin, fluorine resin, and the like. Among them, paraffin wax is often selected from the viewpoint of price.
パラフィンワックス等のワックスは優れた撥水性を備えるので、木質ボード中に添加されたときこれに優れた耐水性を与える。
他方、木質ボードが建材、例えば床材に使われたとき、その床材の表面にいわゆるワックスコーティングを施すと、コーティング剤に含まれる有機成分が木質ボードに浸透する。浸透した有機成分は膨張、変形、変色その他の悪影響を木質ボードに生じさせるおそれがある。このとき、ワックスは有機成分と親和性を有するので、木質ボードに対する当該有機成分の浸透を有効に妨げられない。
Since waxes such as paraffin wax have excellent water repellency, they provide excellent water resistance when added to a wooden board.
On the other hand, when a wooden board is used as a building material, for example, a flooring material, when a so-called wax coating is applied to the surface of the flooring material, an organic component contained in the coating agent penetrates into the wooden board. The permeated organic components can cause swelling, deformation, discoloration and other adverse effects on the wooden board. At this time, since the wax has an affinity with the organic component, the penetration of the organic component into the wooden board is not effectively prevented.
本発明者らは、上記の課題を解決すべく鋭意検討を重ねてきた結果、撥水性組成物としてワックスと石油樹脂とを所定の比率で併用すると、撥水性はもとよりフロアワックス剤をはじめとする有機成分に対しても安定することを見出した。
即ち、この発明の第１の局面は次のように規定される。
木質ボード等の素材に添加させる撥水性組成物であって、
ワックスを７０〜９０重量％、
石油樹脂を３０〜１０重量％、含んでなる撥水性組成物。
As a result of intensive studies to solve the above-mentioned problems, the present inventors have used a wax and petroleum resin in a predetermined ratio as a water-repellent composition. It was found that the organic component is stable.
That is, the first aspect of the present invention is defined as follows.
A water repellent composition added to a material such as a wooden board,
70-90% by weight of wax,
A water-repellent composition comprising 30 to 10% by weight of a petroleum resin.
ここに、ワックスにはパラフィンワックスの他に、オレフィンワックスやモンタンワックス、フィッシャートロプッシュワックスなど、撥水性組成物として汎用的なものを使用できる。
石油樹脂とは石油類のスチームクラッキングによりエチレン、プロピレンなどを製造するエチレンプラントから副生する分解油留分に含まれるジオレフィンおよびモノオレフィン類を単離せずに重合したもので、大別して次の３種に分けられる。分解油留分のうちＣ５留分を原料にしたものを脂肪族系またはＣ５系石油樹脂、Ｃ９留分を原料にしたものを芳香族系またはＣ９系石油樹脂、両者を原料としたものをＣ５Ｃ９共重合石油樹脂と呼ぶ。
Ｃ５系石油樹脂の主成分はイソプレン、ピペリレン、２−メチルブテン−１および２などの共重合体で共役ジオレフィンは環化構造を有することが多い。その軟化点は７０〜１００℃である。Ｃ９系石油樹脂の主成分はスチレン、ビニルトルエン、α−メチルスチレン、インデンの共重合体でその軟化点は８０〜１５０℃である。Ｃ５Ｃ９共重合石油樹脂は前述Ｃ５、Ｃ９の共重合物であり、その軟化点は６０〜１００℃である。
ここに、ワックス及び石油樹脂はともに、従来より、防水性を付与するために木質ボードへ添加させられていた。両者を共用することも特許文献１及び２に示唆されている。より具体的には特許文献１の実施例２においてパラフィンワックス：石油樹脂＝９６重量部：２重量部の配合例が開示されている。同様に、特許文献２の実施例８においてパラフィンワックス：石油樹脂＝９６重量部：１重量部の配合例が開示されている。
これに対し、この発明の第１の局面に記載の発明では、ワックスと石油樹脂との配合比を前者：後者＝７０〜９０重量％：３０〜１０重量％とすることで、フロアワックス剤その他の有機成分に対する耐性の向上を図っている。
Here, in addition to paraffin wax, general-purpose water-repellent compositions such as olefin wax, montan wax, and Fischer-Tropsch wax can be used as the wax.
Petroleum resins are polymerized without isolating diolefins and monoolefins contained in cracked oil fractions by-produced from ethylene plants that produce ethylene, propylene, etc. by steam cracking of petroleum. There are three types. Among the cracked oil fractions, aliphatic or C5 petroleum resins made from C5 fraction as raw materials, aromatic or C9 petroleum resins made from C9 fractions as raw materials, and C5C9 produced from both as raw materials Called copolymerized petroleum resin.
The main component of the C5 petroleum resin is a copolymer such as isoprene, piperylene, 2-methylbutene-1 and 2, and the conjugated diolefin often has a cyclized structure. Its softening point is 70-100 ° C. The main component of the C9 petroleum resin is a copolymer of styrene, vinyltoluene, α-methylstyrene, and indene, and its softening point is 80 to 150 ° C. C5C9 copolymer petroleum resin is a copolymer of the aforementioned C5 and C9, and its softening point is 60 to 100 ° C.
Here, both wax and petroleum resin have been conventionally added to a wooden board in order to impart waterproofness. It is also suggested in Patent Documents 1 and 2 that both are shared. More specifically, in Example 2 of Patent Document 1, a blending example of paraffin wax: petroleum resin = 96 parts by weight: 2 parts by weight is disclosed. Similarly, in Example 8 of Patent Document 2, a blending example of paraffin wax: petroleum resin = 96 parts by weight: 1 part by weight is disclosed.
On the other hand, in the invention described in the first aspect of the present invention, the ratio of the wax and the petroleum resin is the former: the latter = 70 to 90% by weight: 30 to 10% by weight. To improve resistance to organic components.
