Description
本発明は、自動車等の車両、特にそのボディ等の車体、中でもその塗装面へのコーティング剤に関するものである。 The present invention relates to a coating agent for a vehicle such as an automobile, particularly a vehicle body such as a body thereof, and particularly a painted surface thereof.
従来、車体表面のコーティング剤として、湿気硬化性シリコーンオリゴマーを主成分とし、有機官能基で変性されたシリコーンオイルを加えることで、撥水性など種々の性能を向上させた系がよく利用されている。 Conventionally, as a coating agent for the surface of a vehicle body, a system in which various properties such as water repellency are improved by adding a silicone oil mainly composed of a moisture curable silicone oligomer and modified with an organic functional group is often used. .
このようなコーティング組成物としては、特許文献1に開示される車両用コーティング剤を挙げることが出来る。ここでは、湿気硬化性シリコーンオリゴマーと、硬化触媒と、分子の両末端に反応性官能基を少なくとも有する両末端型反応性シリコーンオイルとを含有し、前記両末端型反応性シリコーンオイルの配合割合が、前記湿気硬化性シリコーンオリゴマー１００重量部に対して、２５重量部以上であることを特徴とする車両用コーティング剤が開示されている。 Examples of such a coating composition include a vehicle coating agent disclosed in Patent Document 1. Here, it contains a moisture-curable silicone oligomer, a curing catalyst, and a both-end type reactive silicone oil having at least a reactive functional group at both ends of the molecule, and the blending ratio of the both-end type reactive silicone oil is A vehicle coating agent characterized by being 25 parts by weight or more based on 100 parts by weight of the moisture curable silicone oligomer is disclosed.
しかし、このコーティング組成物で得られる車両表面の光沢被膜は、撥水性においては問題ないが、滑水性、滑り性、擦傷性において問題があることが判明し、その改善が望まれていた。 However, the glossy coating on the vehicle surface obtained with this coating composition has no problem in water repellency, but has been found to have problems in water slidability, slipperiness and scratch resistance, and improvement has been desired.
各種変性シリコーン、特に分子末端のシラノール基やアルコキシ基とシリコーンオリゴマーのアルコキシシリル基とを反応させ、変性シリコーンを固定化する技術があるが、それが十分ではなく、経時的に変性シリコーンが脱離していくことで初期性能の維持が難しい。
There are technologies to fix various modified silicones, in particular silanol groups or alkoxy groups at the molecular terminals, and alkoxysilyl groups of silicone oligomers to immobilize the modified silicone, but this is not sufficient, and the modified silicone will be released over time. It is difficult to maintain the initial performance.
本発明は、本発明の課題は、このような事情の下、炭素原子に結合した水酸基を有する変性シリコーンオイルとシランカップリング剤の有機反応性基とを反応させ、また、シランカップリング剤のアルコキシシリル基とシリコーンアルコキシオリゴマーとを反応させること、すなわち、シランカップリング剤を両者の固定化剤として使用することで、より強固に固定化することができる。
すなわち、本発明は、シリコーンアルコキシオリゴマーと硬化触媒と分子のどちらか片方の末端にカルビノール変性基を有するシリコーンオイルとシランカップリング剤と溶剤からなり、常温で硬化被膜を形成させる塗装表面を保護する車両用コーティング剤である。
また、本発明の車両用コーティング剤においては、カルビノール変性基をジカルビノールとすることができる。
さらに、本発明の車両用コーティング剤は、シランカップリング剤が末端イソシアネートを有するシランカップリング剤若しくは末端グリシジルエーテル基を有するシランカップリング剤をもちいることができる。
また、本発明の車両用コーティング剤は、シリコーンアルコキシオリゴマー３．０〜１５．０質量部、触媒０．１〜２．０質量部、:変性シリコーンオイル、１．０〜１０．０質量部、シランカップリング剤０．１〜１．５質量部、残部が溶剤とすることができる。
さらに、本発明の車両用コーティング剤は、硬化触媒がアルミ系若しくは、チタン系であり、溶剤がイソパラフィン系溶剤若しくはイソパラフィン系溶剤に少量のシリコーン系溶剤を添加したことを特徴とする。
In the present invention, the problem of the present invention is that, under such circumstances, a modified silicone oil having a hydroxyl group bonded to a carbon atom and an organic reactive group of a silane coupling agent are reacted. By reacting an alkoxysilyl group and a silicone alkoxy oligomer, that is, by using a silane coupling agent as a fixing agent for both, it can be more firmly fixed.
That is, the present invention protects the coating surface that forms a cured coating at room temperature, comprising a silicone oil having a carbinol-modified group at one end of a silicone alkoxy oligomer, a curing catalyst, and a molecule, a silane coupling agent, and a solvent. It is a coating agent for vehicles.
In the vehicle coating agent of the present invention, the carbinol-modified group can be dicarbinol.
Furthermore, the vehicle coating agent of the present invention can use a silane coupling agent having a terminal isocyanate or a silane coupling agent having a terminal glycidyl ether group.
Moreover, the coating agent for vehicles of this invention is 3.0-15.0 mass parts of silicone alkoxy oligomers, 0.1-2.0 mass parts of catalyst ,: modified silicone oil, 1.0-10.0 mass parts, The silane coupling agent can be 0.1 to 1.5 parts by mass, and the balance can be the solvent.
Furthermore, the vehicle coating agent of the present invention is characterized in that the curing catalyst is aluminum or titanium, and the solvent is an isoparaffin solvent or an isoparaffin solvent with a small amount of silicone solvent added.
本発明は、上結果より、本発明のコーティング剤は、非常に優れた初期性能を示し、また、非常に高い耐久性を有している。よって、車への施工により、長期にわたり優れた効果（滑水性、滑り性、擦傷性、撥水性等）を持続するコーティング剤となり、非常に有用である。
という利点がある。
From the above results, the coating agent of the present invention exhibits very excellent initial performance and has very high durability. Accordingly, it is a very useful coating agent that can maintain excellent effects (sliding property, slipping property, scratching property, water repellency, etc.) over a long period of time when applied to a vehicle.
There is an advantage.
