【発明の属する技術分野】
本発明は、被覆用組成物に関し、詳しくは撥水撥油性、滑水性を有して汚れにくく、汚れても容易に汚れが除去でき、しかも耐酸性、耐スリ傷性に優れた被膜を形成できる被覆用組成物に関する。
【0002】
【従来技術及びその課題】
自動車、鉄道車両、飛行機、建物等の各種外板の塗膜面は、水や紫外線により経時で徐々に劣化し、また埃、砂塵、排気ガスなどにより汚染されたり、傷つけられるため、通常、該塗膜面の保護、美観維持を目的に、ワックス類等の表面保護剤を塗布することが行われている。自動車用としては、例えばワックスにシリコ−ンオイルを配合したカ−ワックス等が用いられ、これを自動車外板の塗膜上に塗布して撥水被膜を形成しているが、該被膜では架橋構造を形成していないので持続性に劣るものであり、しかも経時で汚れてくるという不具合があった。
【0003】
撥水性を有する架橋膜を形成する樹脂組成物としては、従来、フッ素系あるいはシリコン系の樹脂に硬化剤を配合してなる組成物が提案されている。しかしながらこれらによる被膜は、耐スリキズ性や耐酸性などが不十分であるために、汚染物質が付着しやすく、また除去できなくなり、結果として撥水性も低下してしまうという不具合があった。
【0004】
【課題を解決するための手段】
本発明者らは、上記問題を解決すべく鋭意検討した結果、特定の水酸基含有シロキサンポリマーにコロイダルシリカ及び/又はオルガノシリケ−ト、エポキシ末端シロキサンポリマ−とスルホン酸化合物の反応生成物、及びポリイソシアネ−ト化合物を含有する被覆用組成物を用いることにより、撥水性、滑水性、耐汚染性、耐スリキズ性等に優れた保護被膜を形成しうる被覆用組成物が得られることを見出し本発明に到達した。

【0019】
かくして得られる水酸基含有シロキサンポリマー(A)は、水酸基価が50〜290mgKOH/g、好ましくは60〜200mgKOH/gの範囲内である。該水酸基価が50mgKOH/g未満では硬化性が低下し、得られる被膜の滑水性及びその維持性が低下するので好ましくない。
【0020】
さらに、水酸基含有シロキサンポリマー(A)は、数平均分子量が1,000〜100,000、好ましくは3,000〜50,000の範囲内であることが望ましい。
【0021】
本発明においてコロイダルシリカ及び/又はオルガノシリケ−ト(B)は、被膜の硬度、耐スリキズ性、滑水性を向上させるために配合されるものであり、コロイダルシリカ、及びオルガノシリケ−トを夫々単独で使用してもよいし、さらにこれらの混合物或いはこれらの部分反応物として使用してもよい。

【0024】
上記コロイダルシリカ及びオルガノシリケ−トを反応させる場合には、必要に応じて酸触媒や水溶性有機溶剤をこれらに添加し、水の存在下で加水分解反応させることにより行われる。
【0025】
本発明において上記コロイダルシリカ及びオルガノシリケ−トは、夫々単独で配合できるが、両者の混合物或いは部分反応物を使用した場合には、より多くの量が配合できるので、得られる被膜の硬度や耐スリキズ性の向上には有利である。上記コロイダルシリカ及び/又はオルガノシリケ−ト(B)の使用量は、組成物中の合計樹脂固形分100重量部に対して5〜100重量部、好ましくは10〜80重量部の範囲内が好適である。該使用量が5重量部未満では硬度の向上が得られず、100重量部を越えると被膜が脆くなる恐れがあるので好ましくない。
【0026】

【0031】
シロキサンポリマ−(d)とスルホン酸化合物(e)の反応は、例えば両者を、必要に応じて有機溶剤の存在下で室温〜100℃で混合することによって行なうことができる。もちろん、両者を混合して加熱してもよい。上記有機溶剤としては、例えばトルエン、キシレン、シクロヘキサン、石油エ−テル、ガソリン、ケロシン、ナフサ、クロロホルム、四塩化炭素、二塩化エチレン、2−エチルヘキサノ−ル、ジエチルエ−テル、メチルエチルケトン、メチルイソブチルケトン、イソプロピルアルコ−ル、ブタノ−ル、ジオキサン、鉱物油などが挙げられる。
【0032】
上記の通り得られる反応生成物(C)は、そのままで、又は有機溶剤で希釈或いは一部脱溶剤するなどして固形分濃度を適宜調整し、また未反応のスルホン酸化合物を除去するなどして使用に供することができる。
【0033】
本発明では、上記反応生成物(C)を、組成物中の樹脂固形分100重量部に対して、固形分量で5〜30重量部、好ましくは5〜20重量部含有する。該含有量が5重量部未満では、滑水性の発現が不十分であり、30重量部を越えると、得られる塗膜の強度や硬さが不十分となるので好ましくない。

(1) Pencil hardness: Each test coated plate was subjected to a pencil scratch test according to JIS K-5400 in a constant temperature and humidity chamber at a temperature of 20 ° C. and a humidity of 75% RH.
[0076]
(2) Scratch resistance: A polishing powder (Dalma Cleanser) was mixed with water at 3: 2 to prepare an abrasive, and a dyeing fastness friction tester FR-II (manufactured by Suga Test Instruments Co., Ltd.) was used. The abrasive was adhered to the nell, a load of 500 g was applied, and the coated surface of each test coating plate was rubbed back and forth 20 times. Thereafter, the coated surface was washed with running water, and after natural drying, the 20-degree specular reflectance (20 ° G value) of the coated surface was measured, and the gloss retention with respect to the 20 ° G value before the test was evaluated as follows. .
[0077]
○: 20 ° G gloss retention is 40% or more
Δ: 20 20% or more and less than 40%
×: 〃 Less than 20%
(3) Contamination resistance: Carbon black was used as a contaminant, and this was adhered to the flanks and lightly rubbed against the coated surface of each test coating plate. This was left in a constant temperature and humidity room at 20 ° C. and 75% RH for 24 hours, and then the coated surface was washed with running water, and the degree of contamination of the coated film was visually evaluated.
○: Good
Δ: Some dirt remains
×: Pretty dirty remains
(4) Accelerated weather resistance: Using a sunshine weatherometer, the coated surface state after a 1000 hour test was visually evaluated.
[0078]
○: Almost no change in paint surface
×: Water marks are observed on the coated surface, resulting in a large reduction in gloss
(5) Crack resistance: Each test coating plate was tested for 20 consecutive cycles, with the test of “1 hour standing at 70 ° C. → 1 hour immersion in tap water at 20 ° C. → 1 hour standing at −20 ° C.”. The state of the later coating surface was examined.
[0079]
Y: No abnormality
Δ: Cracking occurred in some areas
×: Cracking occurred on the entire surface
(6) Gasoline resistance: A test plate was fixed horizontally, and approximately 5 cc of regular type gasoline was soaked in a quadruple-folded gauze (50 × 50 mm) and left as it was for 3 minutes. Then, the gauze was removed, and the state of the coated surface after wiping off gasoline with another gaze was observed.
[0080]
Y: No abnormality
Δ: Decreased glossiness of painted surface
×: Gloss reduction and softening of the coated surface occur
(7) Water resistance: The state of the coated surface after immersion in tap water at 20 ° C. for 7 days was examined.
[0081]
Y: No abnormality
×: Dandruff, whitening occurred
(8) Finished appearance: The smoothness of the coating film and the coated skin of each test coating plate were visually evaluated.
[0082]
○: Good
Δ: A little rough skin
×: Pretty skin
(9) Lubricity: After 20 μl of water was dropped on each test coating plate, each test coating plate was tilted at a constant speed, and the tilt angle when water droplets flowed out was examined.
[0083]
(10) Contact angle: A fixed amount (3 μl) of water and paraffin were dropped onto the test coating plate, and the contact angle after 30 seconds was measured.
[0084]
【The invention's effect】
