しかし、特許文献1に記載される自動車用劣化塗膜及び小傷修復兼つや出し剤では、塗布直後には良好な艶および光沢が得られるものの、その後に洗車した場合などには、顕著に艶および光沢が落ち、また、長期にわたって表面の良好な艶および光沢を維持できないという不具合がある。また、薬剤を長期にわたって保存すると、固化を生じるなど、貯蔵安定性に欠けるという不具合もある。 However, the deteriorated coating film for automobiles and small scratch repairing and polishing agent described in Patent Document 1 can obtain a good gloss and gloss immediately after application, but when the vehicle is subsequently washed, the gloss and There are defects that the gloss is lowered and that the surface has a good gloss and gloss cannot be maintained over a long period of time. In addition, when the medicine is stored for a long period of time, there is a problem that it lacks storage stability, such as solidification.
そこで、本発明の目的は、長期にわたって樹脂製品の保護、良好な艶および光沢を維持し、また、洗浄しても良好な艶および光沢を維持することができ、さらには、貯蔵安定性に優れる、樹脂用艶出し保護剤を提供することにある。 Accordingly, an object of the present invention is to protect the resin product over a long period of time, maintain a good gloss and gloss, and maintain a good gloss and gloss even after washing, and further has excellent storage stability. An object of the present invention is to provide a polish-protecting agent for resin.
上記目的を達成するために、本発明の樹脂用艶出し保護剤は、湿気硬化型シリコーンレジンと、硬化触媒と、アルコール系溶剤とを含有することを特徴としている。 In order to achieve the above object, the polish protective agent for resin of the present invention is characterized by containing a moisture curable silicone resin, a curing catalyst, and an alcohol solvent.
また、本発明の樹脂用艶出し保護剤は、さらに、オルガノシロキサンオイルを含有することが好適である。また、この場合には、オルガノシロキサンオイルの配合割合が、湿気硬化型シリコーンレジン100重量部に対して、0.1〜150重量部であることが好適であり、オルガノシロキサンオイルの粘度が、25℃で1000mm2/s以上であることが好適である。 Moreover, it is preferable that the glaze protecting agent for resin of the present invention further contains an organosiloxane oil. In this case, it is preferable that the blending ratio of the organosiloxane oil is 0.1 to 150 parts by weight with respect to 100 parts by weight of the moisture-curable silicone resin, and the viscosity of the organosiloxane oil is 25 It is preferable that it is 1000 mm < 2 > / s or more at ° C.
また、本発明の樹脂用艶出し保護剤は、炭化水素系溶剤を、樹脂用艶出し保護剤の全重量に対して、0.1〜30.0重量部含有することが好適である。 Moreover, it is suitable for the polish protection agent for resins of this invention to contain 0.1-30.0 weight part of hydrocarbon type solvents with respect to the total weight of the polish protection agent for resins.
本発明の樹脂用艶出し保護剤は、作業効率よく樹脂製品の表面に塗布することができ、かつ、塗布直後、洗浄後、さらには、長期にわたる耐久後においても、樹脂製品の表面に良好な艶および光沢を与え、かつ、その樹脂製品の表面を保護することができる。また、貯蔵安定性も良好で、安定した保存を実現することができる。 The polish protective agent for resin of the present invention can be applied to the surface of a resin product with good work efficiency, and is excellent on the surface of the resin product immediately after application, after washing, and even after long-term durability. Gloss and gloss can be imparted and the surface of the resin product can be protected. In addition, the storage stability is good and stable storage can be realized.
本発明の樹脂用艶出し保護剤は、湿気硬化型シリコーンレジン、硬化触媒およびアルコール系溶剤を含有している。 The glazing protective agent for resin of the present invention contains a moisture curable silicone resin, a curing catalyst and an alcohol solvent.
本発明において、湿気硬化型シリコーンレジンは、例えば、分子末端にアルコキシシリル基を有する低分子量のシリコーンアルコキシオリゴマーであって、後述する硬化触媒の存在下で、アルコキシシリル基の架橋により、常温で硬化するものが挙げられる。 In the present invention, the moisture curable silicone resin is, for example, a low molecular weight silicone alkoxy oligomer having an alkoxysilyl group at the molecular end, and is cured at room temperature by crosslinking of the alkoxysilyl group in the presence of a curing catalyst described later.

試験例
2×2cmにカットしたウレタンスポンジに、各実施例および各比較例で得られた樹脂用艶出し保護剤を1.0gとり、未塗装部分を14等分した樹脂製バンパ(平成8年式トヨタ自動車、カローラバンに装着して3万km以上走行したもの)に均一に塗布した。
Test Example Resin bumper made by taking 1.0 g of the polish protectant for resin obtained in each Example and each Comparative Example on urethane sponge cut to 2 × 2 cm, and dividing the unpainted portion into 14 equal parts (1996) Applied to Toyota Motor Co., a Corolla van that traveled over 30,000 km).
塗布してから5分間乾燥させた後、清浄なタオルを用いて、バンパ表面を拭き取った。 After applying and drying for 5 minutes, the surface of the bumper was wiped off with a clean towel.
その後、さらに30分間乾燥させた後、バンパ表面の艶および皮膜の均一性を目視にて確認した。その結果を表1に示す。 Thereafter, after further drying for 30 minutes, the gloss of the bumper surface and the uniformity of the film were visually confirmed. The results are shown in Table 1.
なお、塗布処理時の作業性についても併せて評価した。その結果を表1に示す。 The workability during the coating process was also evaluated. The results are shown in Table 1.
また、拭き取り後、1日間自然乾燥させた後、カーシャンプーを含浸した自動車用の洗車スポンジを用いて、バンパ表面を洗浄し、水洗乾燥後のバンパ表面の艶の状態を目視にて確認し、耐洗浄性を評価した。その結果を表1に示す。 In addition, after wiping, after naturally drying for 1 day, using a car wash sponge impregnated with car shampoo, wash the bumper surface, visually check the gloss state of the bumper surface after washing and drying, Wash resistance was evaluated. The results are shown in Table 1.
また、上記とは別に、拭き取り後、1ヶ月間放置した後、塗布処理したバンパ表面の美観と塗布処理を施していないバンパ表面の美観とを比較し、耐久性を評価した。その結果を表1に示す。 Separately from the above, after wiping and leaving for one month, the aesthetics of the applied bumper surface was compared with the aesthetics of the bumper surface that had not been applied, and durability was evaluated. The results are shown in Table 1.
また、各実施例および各比較例で得られた樹脂用艶出し保護剤20mlを容量50mlのガラス製サンプル瓶に入れ、50℃の雰囲気下で1ヶ月間保存した後、樹脂用艶出し保護剤の貯蔵安定性を評価した。その結果を表1に示す。 Also, 20 ml of the resin glaze protectant obtained in each of the examples and each comparative example was placed in a glass sample bottle having a capacity of 50 ml and stored for one month in an atmosphere at 50 ° C. Was evaluated for storage stability. The results are shown in Table 1.
