本發明是有關於一種含有單末端含烷氧基的矽氧烷的塗佈組成物、將該組成物硬化而成的塗佈被膜及具有該被膜的物品。The present invention relates to a coating composition containing an alkoxy group-containing siloxane at one end, a coating film formed by curing the composition, and an article having the film.

先前，對於建材或塗裝鋼板等，以賦予疏水性以及提高美觀、保護表面等為目的，實施如下操作，即，藉由塗佈含有矽酮樹脂的塗佈劑組成物，並進行利用布擦拭未硬化的組成物的操作來形成均勻的被膜。Previously, for building materials or coated steel plates, for the purpose of imparting hydrophobicity, improving aesthetics, and protecting the surface, the following operations were carried out by applying a coating composition containing silicone resin and wiping with a cloth The uncured composition is manipulated to form a uniform film.

在專利文獻1、專利文獻2、專利文獻3以及專利文獻4中，記載了利用有機溶劑稀釋在分子鏈末端具有烷氧基矽烷基的反應性矽酮樹脂的組成物。在專利文獻5中記載了雙層塗佈層：第一層使用將在分子鏈末端具有烷氧基矽烷基的反應性矽酮樹脂於高沸點（蒸餾溫度範圍185℃以上）的異鏈烷烴系溶劑中稀釋後所得的組成物，第二層使用含有具有胺基的有機聚矽氧烷的組成物。在專利文獻6中，揭示了利用有機溶劑稀釋在分子鏈末端具有烷氧基矽烷基的反應性矽氧烷與氟代烷基矽烷的塗佈組成物，且記載了藉由利用該組成物處理鋁基材，並在150℃下加熱硬化，可獲得滑水性優異的熱交換器用鋁塗層劑。 [現有技術文獻] [專利文獻]Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4 describe a composition in which a reactive silicone resin having an alkoxysilyl group at the molecular chain terminal is diluted with an organic solvent. Patent Document 5 describes a two-layer coating layer: the first layer uses a reactive silicone resin having an alkoxysilyl group at the end of the molecular chain at a high boiling point (distillation temperature range of 185°C or more) of an isoparaffin system In the composition obtained after dilution in the solvent, a composition containing an organopolysiloxane having an amine group is used for the second layer.

[專利文獻1]日本專利特開2009-138063號公報 [專利文獻2]日本專利特開2009-138062號公報 [專利文獻3]日本專利特開2013-166957號公報 [專利文獻4]日本專利特開2010-202717號公報 [專利文獻5]日本專利特開2012-241093號公報 [專利文獻6]日本專利第5891043號[Patent Document 1] Japanese Patent Laid-Open No. 2009-138063 [Patent Document 2] Japanese Patent Laid-Open No. 2009-138062 [Patent Document 3] Japanese Patent Laid-Open No. 2013-166957 [Patent Document 4] Japanese Patent Laid-Open No. 2010-202717 [Patent Document 5] Japanese Patent Laid-Open No. 2012-241093 [Patent Document 6] Japanese Patent No. 5891043

[發明所欲解決之課題] 但是，如所述專利文獻中記載般的先前的塗佈劑組成物雖然施工性優異，但在滑水性方面不充分。另外，在專利文獻6中記載了面向鋁翅片的滑水性優異的塗佈劑組成物，且記載了為了獲得被膜而在進行浸漬塗佈等之後進行加熱硬化的步驟，但若藉由利用布的擦拭操作塗敷該專利文獻6記載的塗佈組成物，則產生如下問題：乾燥慢，硬化性差，且無法獲得充分的膜厚，防水性差。另外，針對所述問題，若為了增加膜厚而提高矽酮濃度，則會產生組成物的施工性降低的問題。[The problem to be solved by the invention] However, although the conventional coating agent composition as described in the said patent document is excellent in workability, it is inadequate in terms of water-sliding property. In addition, Patent Document 6 describes a coating agent composition with excellent water sliding properties for aluminum fins, and describes a step of performing heat curing after dip coating or the like in order to obtain a film. However, if a cloth is used The application of the coating composition described in Patent Document 6 in the wiping operation caused the following problems: slow drying, poor curability, insufficient film thickness, and poor water resistance. In addition, in order to address the above-mentioned problems, if the silicone concentration is increased in order to increase the film thickness, the workability of the composition is reduced.

本發明是鑑於所述情況而成，其目的在於提供一種塗佈組成物，在藉由利用布的擦拭操作塗敷未硬化的塗佈劑組成物的方法中，可形成均勻的被膜，且塗敷時的施工性優異，進而施工後的被膜的硬化性及滑水性優異。 [解決課題之手段]The present invention is made in view of the above circumstances, and its object is to provide a coating composition that can form a uniform coating film in a method of applying an uncured coating agent composition by wiping with a cloth. The workability at the time of application is excellent, and the curability and water slidability of the film after construction are excellent. [Means to solve the problem]

As a result, they have found that a linear organopolysiloxane containing an alkoxysilyl group only at one end has an alkoxysilyl group at both ends. In the coating agent composition of the fluoroalkane compound, curing catalyst and organic solvent, by adjusting the amount of solvent, a coating agent that can be applied well even by the wiping method is prepared. Furthermore, by determining the boiling point or distillation range of the solvent, when applying by the wiping method, it can be wiped uniformly during application, and the workability is excellent. The coating agent remains on the substrate in a liquid form for an appropriate time, so the film The forming ability is improved, and the hardenability at room temperature is also improved. In addition, the coating film after construction has good water slidability, thereby completing the present invention.

When the amount of the component (B) is equal to or greater than the lower limit, the coating composition of the present invention has appropriate curability and can form a uniform cured film. In addition, when the blending amount of the component (B) is below the upper limit, the coating composition of the present invention can obtain better workability.

The organic solvent is preferably an aliphatic saturated hydrocarbon solvent. The number of carbon atoms of the aliphatic saturated hydrocarbon is not particularly limited, as long as the boiling point or distillation range of the solvent satisfies the above range. For example, as an aliphatic saturated hydrocarbon solvent having the boiling point or distillation range in the above range, a solvent containing aliphatic saturated hydrocarbons having 9 to 12 carbon atoms as a main component can be cited. Examples are isoparaffins, normal paraffins, and cycloalkanes, and isoparaffin solvents are particularly preferred.

In addition, when the boiling point or the distillation range is below the upper limit, the coating composition of the present invention can have appropriate volatility, and in addition, better curability can be obtained. Here, because the component is a mixture, etc., when the boiling point is not a single temperature, the distillation range (temperature range from the initial boiling point to the dry point) is 150°C to 180°C, preferably 160°C It is only necessary to be within the range of -180°C instead of the boiling point. At this time, from the viewpoint of workability, the temperature difference (temperature distribution) between the initial boiling point and the dry point is particularly preferably in the range of 20°C.

脂肪族飽和烴溶劑只要具有所述沸點或蒸餾範圍即可，可使用市售品。作為該市售品，例如可列舉丸善石油化學股份有限公司製品的馬卡蘇（MARUKASOL）R（沸點177℃）、JXTG能量（JXTG energy）股份有限公司製品的卡特思（CACTUS）正鏈烷烴N-10（初餾點169℃、乾點173℃）、埃克森美孚（EXXONMOBIL）股份有限公司製品的艾素帕（isopar）G（初餾點166℃、乾點177℃）等。該些脂肪族飽和烴化合物可單獨使用，亦可使用多種混合物。在混合物的情況下，若蒸餾範圍包含在所述溫度範圍內，則亦可含有化合物單獨的沸點不在150℃～180℃的範圍內的脂肪族飽和烴化合物。The aliphatic saturated hydrocarbon solvent should just have the boiling point or distillation range mentioned above, and a commercially available product can be used. Examples of the commercially available products include MARUKASOL R (boiling point 177°C) manufactured by Maruzen Petrochemical Co., Ltd., and CACTUS normal paraffin N manufactured by JXTG Energy Co., Ltd. -10 (initial boiling point 169°C, dry point 173°C), isopar G (initial boiling point 166°C, dry point 177°C) manufactured by ExxonMobil Co., Ltd. etc. These aliphatic saturated hydrocarbon compounds can be used singly or as a mixture of multiple types. In the case of a mixture, if the distillation range is included in the temperature range, it may contain an aliphatic saturated hydrocarbon compound whose individual boiling point is not within the range of 150°C to 180°C.

如表2所示，關於使用兩末端具有烷氧基矽烷基的聚矽氧烷來代替本發明的（A）成分的比較例7的塗佈組成物，滑水性差。使用本發明的（B）成分以外的矽烷化合物的比較例8、比較例9及比較例10的塗佈組成物的滑水性不良。As shown in Table 2, the coating composition of Comparative Example 7 in which the polysiloxane having alkoxysilyl groups at both ends was used instead of the component (A) of the present invention had poor water slip. The coating compositions of Comparative Example 8, Comparative Example 9, and Comparative Example 10 that used silane compounds other than the (B) component of the present invention had poor water sliding properties.

另外，如表2所示，（B）成分的調配量過少的比較例2的塗佈組成物的硬化性及滑水性差，（B）成分的調配量過多的比較例1的塗佈組成物的施工性差。進而，關於使用不滿足本發明的蒸餾範圍的異鏈烷烴有機溶劑來代替本發明的（C）成分的比較例11及比較例12的塗佈劑，施工性及硬化性不充分。（C）成分的調配量過少的比較例3的塗佈劑由於含有高濃度的（A）成分，因此無法獲得充分的施工性。另外，關於（C）成分的調配量超過本發明的上限值的比較例4的塗佈組成物，組成物變得稀薄，硬化性變得不良。In addition, as shown in Table 2, the coating composition of Comparative Example 2 in which the blending amount of (B) component is too small has poor curability and water slip, and the coating composition of Comparative Example 1 in which the blending amount of component (B) is too large The construction is poor. Furthermore, with regard to the coating agents of Comparative Example 11 and Comparative Example 12 in which an isoparaffin organic solvent that does not satisfy the distillation range of the present invention is used instead of the component (C) of the present invention, workability and curability are insufficient. (C) Since the coating agent of Comparative Example 3 in which the compounding amount of the component is too small contains the (A) component at a high concentration, sufficient workability cannot be obtained. In addition, with regard to the coating composition of Comparative Example 4 in which the blending amount of the component (C) exceeds the upper limit of the present invention, the composition becomes thinner and the curability becomes poor.

進而，（D）成分的調配量過少的比較例5的塗佈劑的硬化性差。（D）成分的調配量過多的比較例6的塗佈組成物的施工性差。進而，不含（A）成分～（D）成分中的任一者的比較例13～比較例16的塗佈組成物的硬化性、滑水性及施工性中的至少一種差，未獲得全部具有優異的性質的被膜。Furthermore, the coating agent of Comparative Example 5 in which the blending amount of the component (D) was too small had poor curability. (D) The coating composition of Comparative Example 6 in which the blending amount of the component is too large has poor workability. Furthermore, the coating compositions of Comparative Examples 13 to 16 that do not contain any of the components (A) to (D) are poor in at least one of curability, water slidability, and workability, and not all have Film with excellent properties.

相對於此，如表1的實施例1～實施例15所示，本發明的塗佈組成物的施工性均良好，且賦予了具有優異的滑水性及硬化性的被膜。 [產業上的可利用性]In contrast, as shown in Examples 1 to 15 in Table 1, the coating composition of the present invention has good workability, and a coating film having excellent water slidability and curability is provided. [Industrial availability]

本發明的塗佈組成物在未硬化狀態下利用布擦拭而形成被膜時的施工性及室溫下的硬化性優異。進而，硬化後的被膜可具有優異的滑水性。因此，作為在汽車及電車等車輛、建材、成形體等的金屬面、塗裝面或樹脂面等上形成用於賦予滑水性及防污性能的薄膜塗佈層的塗佈劑有用。The coating composition of the present invention is excellent in workability and curability at room temperature when a film is formed by wiping with a cloth in an uncured state. Furthermore, the cured film can have excellent water slidability. Therefore, it is useful as a coating agent for forming a thin film coating layer for imparting water slidability and antifouling properties on metal surfaces, painted surfaces, or resin surfaces of vehicles such as automobiles and trains, building materials, molded articles, and the like.
