Abstract
Description
本発明は、防汚剤、特に、自動車等の車両の塗装に塗布されて汚れを防ぐことのできる防汚剤に関するものである。 The present invention relates to an antifouling agent, and more particularly to an antifouling agent that can be applied to the coating of a vehicle such as an automobile to prevent contamination.
自動車等の車体の塗装の汚れを防ぐために、通常は撥水コートが塗布形成される。撥水コートが塗布形成された塗装の表面は、雨水や汚水が付着した場合に、これらを水滴として弾き、車体から流れ落とさせることから、汚れを付着させない。 In order to prevent stains on the body of an automobile or the like, a water repellent coat is usually applied and formed. The surface of the coating on which the water-repellent coat is formed is repelled as raindrops or sewage and drops off from the vehicle body so that it does not adhere to the surface.
したがって、一般的な門型洗車機においては、界面活性剤を含む洗浄剤で車体の塗装面を洗浄した後、必要に応じてワックスを塗布し、仕上げ処理として撥水コートが塗布形成される（特許文献１）。撥水コートは、例えばアミノシリコーンを含む組成物である。 Therefore, in a general portal-type car wash machine, after washing the painted surface of the vehicle body with a detergent containing a surfactant, a wax is applied as necessary, and a water-repellent coat is applied and formed as a finishing process ( Patent Document 1). The water repellent coat is a composition containing, for example, amino silicone.
しかし、最終仕上げに撥水コートが塗布形成された塗装は、水を水滴状に弾くことから、汚れを付着させない効果がある反面、塗装上に水滴が付着している状態で日光が当たると、水滴が凸レンズの役目を果たし塗装表面を傷める場合がある。また塗装上に付着した水滴が蒸発したとき、水滴中に含まれる油分やミネラル分が塗装上に残存してリング状のシミが発生する場合がある。 However, the coating with a water repellent coat applied to the final finish repels water in the form of water droplets, so it has the effect of preventing dirt from adhering to it.On the other hand, if sunlight is applied with water droplets on the coating, Water drops can act as a convex lens and damage the painted surface. In addition, when water droplets adhering to the coating evaporate, oil or minerals contained in the water droplet may remain on the coating and ring-shaped spots may occur.
防汚剤に関して、コロイド粒子の形状が鎖状のシリカゾルを含有する防汚剤組成物がある（特許文献２）。この防汚剤組成物を塗布することにより形成される被膜は、親水性が高いため、表面に煤塵などの汚染物質が付着するのを防止できるとともに、表面に汚染物質が付着したとしても水により容易に洗い流すことができるとされている。 Regarding antifouling agents, there is an antifouling agent composition containing a silica sol in which colloidal particles have a chain shape (Patent Document 2). The film formed by applying this antifouling agent composition has high hydrophilicity, so it is possible to prevent contaminants such as dust from adhering to the surface, and even if contaminants adhere to the surface, It can be easily washed away.
しかしながら、引用文献２に記載された防汚剤組成物は、ロールコート法等の慣用のコーティング法を用いることができるとの記載はあるものの、実施例に記載があるように実質的には、防汚剤組成物を含浸させた不織布を用いて塗布するものである。したがって、洗車機で用いられる用途には、必ずしも十分ではなかった。 However, the antifouling agent composition described in Reference 2 has a description that a conventional coating method such as a roll coating method can be used, but as described in the examples, substantially, It applies | coats using the nonwoven fabric impregnated with the antifouling agent composition. Therefore, it was not necessarily sufficient for the application used in a car wash machine.
そこで、本発明の目的は、水滴により塗装表面を傷めたりリング状のシミが発生したりすることがない、自動車等の車両車体の防汚性に優れた防汚剤を提供することにある。 Accordingly, an object of the present invention is to provide an antifouling agent excellent in antifouling properties of a vehicle body such as an automobile, which does not damage the painted surface or cause ring-shaped spots due to water droplets.
本発明者らは、防汚剤について鋭意研究を重ね、車体表面を撥水状態よりも水になじみ易い、疎水状態にすることに着目し、そこから更に、疎水状態にし得る好適な防汚剤を追求した結果、防汚剤としてポリアミン化合物を使用することで車体表面を効率的に疎水化できることを見出し、本発明に至った。 The inventors of the present invention have made extensive studies on the antifouling agent, and have focused on making the surface of the vehicle body in a hydrophobic state, which is more compatible with water than in a water-repellent state. As a result, the inventors have found that the surface of the vehicle body can be efficiently hydrophobized by using a polyamine compound as an antifouling agent, and the present invention has been achieved.
上記知見に基づく本発明の防汚剤は、ポリアミンを含有することを特徴とする。
本発明の防汚剤においては、更に、非イオン界面活性剤を含有することが好ましく、また、更に、水を含有することが好ましい。本発明の防汚剤は、塗膜表面の水に対する接触角が８０°以下であることが好ましい。本発明の防汚剤は、車両の塗装された部分に塗布されるのが好ましく、門型洗車機に用いられて車両に塗布されるのが最適である。
The antifouling agent of the present invention based on the above findings contains a polyamine.
The antifouling agent of the present invention preferably further contains a nonionic surfactant, and preferably further contains water. As for the antifouling agent of this invention, it is preferable that the contact angle with respect to the water of the coating-film surface is 80 degrees or less. The antifouling agent of the present invention is preferably applied to a painted portion of a vehicle, and is optimally applied to a vehicle using a portal type car wash machine.
本発明によれば、車体表面の汚れを防ぐことができ、美観の向上や車体表面の劣化を防ぐことができる。 According to the present invention, it is possible to prevent the surface of the vehicle body from being soiled, and to improve the appearance and the deterioration of the surface of the vehicle body.
以下、本発明の防汚剤をより具体的に説明する。
本発明の防汚剤は、ポリアミンを含有するものである。ポリアミンを含有する防汚剤を塗布された塗装表面は、疎水性を示し、車体表面上の水が、一つの塊のような水膜となって流れ落ちるようになる。したがって、従来の撥水コートのように、塗布された表面が、水を水滴状に弾くことはないので、水滴のレンズ効果により塗装を痛めることがない。また、従来の撥水コートのように、塗装上に付着した水滴が蒸発したとき、水滴中に含まれる油分やミネラル分が塗装上に残存してリング状のシミが発生することもない。
Hereinafter, the antifouling agent of the present invention will be described more specifically.
The antifouling agent of the present invention contains a polyamine. The coating surface to which the antifouling agent containing polyamine is applied exhibits hydrophobicity, and the water on the surface of the vehicle body flows down as a water film like a lump. Therefore, unlike the conventional water-repellent coat, the applied surface does not repel water in the form of water droplets, so that the coating effect is not damaged by the lens effect of water droplets. In addition, unlike the conventional water-repellent coat, when water droplets adhering to the coating evaporate, the oil and minerals contained in the water droplets do not remain on the coating and ring-shaped spots are not generated.

本発明の防汚剤は、水を含む溶液又は乳液の態様とされる。有効成分の種類にもよるが、有効成分としてのポリアミンの濃度が１〜５０質量％程度に調製されたものが好ましい。有効成分濃度が１質量％に満たないと疎水性に乏しく、５０質量％を超えると、分散性に乏しい。非イオン界面活性剤を含む場合は、非イオン界面活性剤の濃度は、０．１〜１０質量％が好ましい。０．１質量％に満たないと基材への濡れ性に乏しい。また、１０質量％を超えると基材への吸着性に乏しい。防汚剤を用いて、洗車機等を介して車体に施用して洗浄する等の洗車処理に際しては、実用的には、上記好適濃度の１０〜３０００倍になるまで水で希釈するのがよい。洗車機では、容器に収容された防汚剤を、水と共に圧送して車両の塗装面に供給することから、容器に収容された防汚剤中のポリアミン濃度１〜５０質量％から、１０〜３０００倍に希釈された濃度で車両に塗布される。 The antifouling agent of the present invention is in the form of a solution or emulsion containing water. Although it depends on the type of active ingredient, it is preferable that the concentration of polyamine as the active ingredient is adjusted to about 1 to 50% by mass. When the active ingredient concentration is less than 1% by mass, the hydrophobicity is poor, and when it exceeds 50% by mass, the dispersibility is poor. When the nonionic surfactant is included, the concentration of the nonionic surfactant is preferably 0.1 to 10% by mass. If it is less than 0.1% by mass, the wettability to the substrate is poor. Moreover, when it exceeds 10 mass%, the adsorptivity to a base material is scarce. In car wash processing such as applying antifouling agent to a vehicle body through a car wash machine or the like for washing, it is practically preferable to dilute with water until the preferred concentration is 10 to 3000 times. . In the car wash machine, the antifouling agent accommodated in the container is pumped together with water and supplied to the painted surface of the vehicle, so that the polyamine concentration in the antifouling agent accommodated in the container is 1 to 50% by mass, It is applied to the vehicle at a concentration diluted 3000 times.
また、本発明の防汚剤には、必要に応じ、本発明の目的を損なわない範囲で、有機溶剤、紫外線吸収剤、染料、防汚剤、防腐剤などの任意の添加成分を配合することができる。 In addition, the antifouling agent of the present invention may be blended with optional additional components such as organic solvents, ultraviolet absorbers, dyes, antifouling agents, preservatives and the like as long as the purpose of the present invention is not impaired. Can do.
本発明の防汚剤は疎水性であり、防汚剤の被膜が形成された表面における水に対する接触角は８０°以下が好ましい。８０°を超えるような接触角では、疎水性の防汚剤としては十分ではないからである。 The antifouling agent of the present invention is hydrophobic, and the contact angle with water on the surface on which the antifouling agent film is formed is preferably 80 ° or less. This is because a contact angle exceeding 80 ° is not sufficient as a hydrophobic antifouling agent.
本発明の防汚剤は、自動車等の車両の塗装に対して、防汚性付与のために用いられて好適である。防汚剤が塗布される塗装表面は、塗装上にワックスが塗布形成されていてもよい。最終的な塗装表面に本発明の防汚剤が塗布されれば、その表面が疎水性を示し、本発明で所期した防汚性の効果が表れる。 The antifouling agent of the present invention is suitably used for imparting antifouling properties to coating of vehicles such as automobiles. The coating surface to which the antifouling agent is applied may be formed by applying wax on the coating. If the antifouling agent of this invention is apply | coated to the final coating surface, the surface will show hydrophobicity, and the antifouling effect expected by this invention will appear.
