Description
本発明は、新規な弱溶剤形塗料組成物及びその塗装方法に関するものである。 The present invention relates to a novel weak solvent paint composition and a coating method thereof.
従来、建築物、土木構造物等においては、その躯体の保護や美観性の向上等を目的として、各種の塗料によって塗装仕上げが行われており、トルエン、キシレン等の芳香族炭化水素系溶剤を媒体とする強溶剤形塗料が多く用いられてきた。これに対し、近年、環境や健康に対する意識が高まっており、塗装時の安全性や、作業衛生の点、あるいは大気汚染への影響等を考慮し、このような芳香族炭化水素系溶剤の使用を抑える動きが強まっている。 Conventionally, buildings, civil engineering structures, etc. have been painted with various paints for the purpose of protecting the enclosure and improving aesthetics, and using aromatic hydrocarbon solvents such as toluene and xylene. Many strong solvent-type paints have been used as media. On the other hand, in recent years, awareness of the environment and health has increased, and the use of such aromatic hydrocarbon solvents is considered in consideration of safety during painting, occupational hygiene, and air pollution. There is an increasing movement to control
このような動きに対応するため、塗料としては、脂肪族炭化水素系溶剤を用いる弱溶剤形塗料への転換が要望されるようになってきた。このような弱溶剤形塗料は、強溶剤形塗料に比べ、低毒性であり、作業上の安全性が高く、さらには大気汚染に対する影響も小さいという長所をもつため、環境対応型の塗料として好ましいものである。 In order to cope with such a movement, it has been demanded that the paint be changed to a weak solvent type paint using an aliphatic hydrocarbon solvent. Such weak solvent type paints are preferable as environmentally friendly paints because they have the advantages of low toxicity, high work safety and little influence on air pollution compared to strong solvent type paints. Is.
このような弱溶剤形塗料として、酸化硬化形樹脂を使用したものが知られている。例えば、特開２００１−２６２０５５号公報（特許文献１）には、エポキシ基等を有するビニル樹脂に不飽和脂肪酸を反応させた後、さらにイソシアネート化合物を反応させてなる樹脂成分を含む塗料組成物が記載されている。該公報に記載の塗料組成物は、不飽和脂肪酸に含まれる反応性二重結合同士の酸化によって架橋反応を生じさせるものであり、その硬化触媒として、オクチル酸コバルト、ナフテン酸コバルト等の金属ドライヤーが使用されている。 As such a weak solvent-type paint, one using an oxidation-curing resin is known. For example, JP-A-2001-262055 (Patent Document 1) discloses a coating composition containing a resin component obtained by reacting an unsaturated fatty acid with a vinyl resin having an epoxy group or the like and then reacting with an isocyanate compound. Have been described. The coating composition described in this publication causes a crosslinking reaction by oxidation of reactive double bonds contained in an unsaturated fatty acid, and a metal dryer such as cobalt octylate or cobalt naphthenate as a curing catalyst thereof. Is used.
このような酸化硬化形の塗料における硬化性を高める手法として、金属ドライヤーとともに１，１０−フェナントロリンや、ビピリジル等の含窒素化合物を使用することが知られている（特開平４−３３４３９３号公報、特開平６−１７２６８９号公報等）。上記特許文献１においても、金属ドライヤーの触媒作用を高める目的で、１，１０−フェナントロリン等を併用することが記載されている。
しかし、このような含窒素化合物は、塗料を着色してしまう場合があり、また形成塗膜における経時的な黄変を引き起こす場合もある。そのため、特に白色系の塗料においては使用しづらく、改善が求められている状況である。
As a technique for enhancing the curability in such an oxidation-curing type paint, it is known to use a nitrogen-containing compound such as 1,10-phenanthroline and bipyridyl together with a metal dryer (Japanese Patent Laid-Open No. 4-334393, Japanese Patent Laid-Open No. 6-17289). The above Patent Document 1 also describes that 1,10-phenanthroline or the like is used in combination for the purpose of enhancing the catalytic action of the metal dryer.
However, such a nitrogen-containing compound may color the paint, and may cause yellowing over time in the formed coating film. For this reason, it is difficult to use, especially for white paints, and there is a demand for improvement.
本発明は、上述のような問題点に鑑みなされたものであり、酸化硬化形樹脂をバインダーとする塗料において、その硬化性を高めるとともに、塗料の着色及び塗膜の経時的な色変化を抑制することを目的とするものである。
本発明者は、このような目的を達成するため鋭意検討を行った結果、酸化硬化形樹脂、金属ドライヤー、及び特定の含窒素化合物を含む塗料組成物に想到し、本発明の完成に至った。
The present invention has been made in view of the above-described problems, and in a paint using an oxidatively curable resin as a binder, the curability is improved and the color of the paint and the color change of the coating film over time are suppressed. It is intended to do.
As a result of intensive studies to achieve the above object, the present inventor has conceived a coating composition containing an oxidatively curable resin, a metal dryer, and a specific nitrogen-containing compound, and has completed the present invention. .
すなわち、本発明は以下の特徴を有するものである。
１．エポキシ基含有ビニル単量体と、この単量体と共重合可能な他のビニル単量体とを共重合させた後、前記エポキシ基含有ビニル単量体に不飽和脂肪酸を付加させて得られた酸化硬化形樹脂、酸化チタン、金属ドライヤー、及び含窒素化合物を含み、全溶剤のうち５０重量％以上が脂肪族炭化水素である塗料組成物であって、該含窒素化合物として、加水分解性シリル基含有ケチミン化合物を酸化硬化形樹脂の固形分１００重量部に対し０．１〜２０重量部含むことを特徴とする塗料組成物。
２．基材に対し下塗材を塗装した後、上塗材として１．記載の塗料組成物を塗装することを特徴とする塗装方法。
３．前記下塗材がエポキシ樹脂下塗材である２．記載の塗装方法。
That is, the present invention has the following characteristics.
1. It is obtained by copolymerizing an epoxy group-containing vinyl monomer and another vinyl monomer copolymerizable with this monomer, and then adding an unsaturated fatty acid to the epoxy group-containing vinyl monomer. A coating composition in which 50% by weight or more of the total solvent is an aliphatic hydrocarbon, and includes hydrolyzable as the nitrogen-containing compound. A coating composition comprising 0.1 to 20 parts by weight of a silyl group-containing ketimine compound with respect to 100 parts by weight of a solid content of an oxidation-curable resin.

本発明の塗料組成物は、以上のような各成分を常法により均一に撹拌・混合して製造することができる。（Ａ）成分の種類によっては、流通時に２液型の形態としておき、塗装時に混合して使用することも可能である。 The coating composition of the present invention can be produced by uniformly stirring and mixing the above-described components by a conventional method. Depending on the type of component (A), it is possible to use a two-component form at the time of distribution and to mix and use at the time of painting.
本発明の塗料組成物は、コンクリート、モルタル、磁器タイル、サイディングボード、押出成形板、金属、ガラス、プラスチック、木材、合板等の各種基材の表面仕上げに使用することができる。これら基材は、その表面に旧塗膜を有するものであってもよい。本発明組成物は、主に建築物、土木構築物等の躯体の保護に使用でき、通常は上塗材として使用する。
本発明の塗料組成物を塗装する際には、基材に直接塗装することもできるし、何らかの表面処理（シーラー、プライマー、サーフェーサ、フィラー、パテ等の下塗材による下地処理等）を施した上に塗装することも可能である。
The coating composition of the present invention can be used for surface finishing of various base materials such as concrete, mortar, porcelain tile, siding board, extruded plate, metal, glass, plastic, wood, plywood and the like. These base materials may have an old coating film on the surface thereof. The composition of the present invention can be used mainly for protecting buildings such as buildings and civil engineering structures, and is usually used as a coating material.
When the coating composition of the present invention is applied, it can be applied directly to the substrate, or after some surface treatment (such as a base treatment with a primer such as a sealer, primer, surfacer, filler, or putty). It is also possible to paint on.
基材に対し下塗材を塗装した後、上塗材として本発明組成物を塗装する場合、下塗材としては公知または市販の各種下塗材が使用できる。具体的に下塗材としては、例えば、アクリル樹脂下塗材、エポキシ樹脂下塗材、ウレタン樹脂下塗材、塩化ゴム系下塗材等が挙げられる。このような下塗材は、クリヤータイプ、着色タイプのいずれであってもよい。また、リン酸塩系、モリブデン酸塩系、亜鉛系等の防錆顔料を含むものであってもよい。 In the case where the composition of the present invention is applied as a top coating material after coating the base material on the base material, various known or commercially available base coating materials can be used.

Such an undercoat material may be either a clear type or a colored type. Further, it may contain a rust preventive pigment such as phosphate, molybdate or zinc.
このうち、本発明ではエポキシ樹脂下塗材を使用した場合において、顕著な効果を得ることができる。通常、酸化硬化形樹脂及び金属ドライヤーを含む上塗材をエポキシ樹脂下塗材の上に塗装すると、かかる下塗材と金属ドライヤーとの相互作用により、上塗材の反応性が低下する場合がある。そのため、上塗材を２回以上塗り重ねた際に、下層の上塗材塗膜が溶解する現象や浮き上がる現象（リフティング）が生じやすくなる。これに対し、本発明組成物では上述の（Ｃ）成分の硬化促進効果等により、このような不具合の発生を抑制することができ、塗装作業性、仕上り性等を高めることができる。 Among these, in the present invention, when an epoxy resin primer is used, a remarkable effect can be obtained. Usually, when an overcoating material containing an oxidation-curing resin and a metal dryer is applied on an epoxy resin undercoat material, the reactivity of the overcoat material may decrease due to the interaction between the undercoat material and the metal dryer. Therefore, when the top coating material is applied twice or more, a phenomenon in which the lower top coating material coating film is dissolved or a phenomenon of lifting (lifting) is likely to occur. On the other hand, in the composition of the present invention, the occurrence of such problems can be suppressed due to the effect of promoting the curing of the above-described component (C), and coating workability, finishability and the like can be improved.
エポキシ樹脂下塗材としては、バインダー成分として１種または２種以上のエポキシ樹脂を含むものが使用できる。エポキシ樹脂としては、例えばビスフェノールＡ型エポキシ樹脂、ビスフェノールＦ型エポキシ樹脂、フェノールノボラック型エポキシ樹脂、アルキルエーテル型エポキシ樹脂、水添ビスフェノールＡ型エポキシ樹脂等、あるいはこれらの変性物等が挙げられる。
エポキシ樹脂下塗材の形態は、１液型、２液型のいずれであってもよい。２液型の場合、硬化剤としてはアミン化合物等を含むものが使用できる。
As an epoxy resin primer, what contains 1 type, or 2 or more types of epoxy resins as a binder component can be used. Examples of the epoxy resin include bisphenol A type epoxy resin, bisphenol F type epoxy resin, phenol novolac type epoxy resin, alkyl ether type epoxy resin, hydrogenated bisphenol A type epoxy resin, and modified products thereof.
The form of the epoxy resin primer may be either one-pack type or two-pack type. In the case of the two-component type, a curing agent containing an amine compound or the like can be used.
このような下塗材は、例えば、刷毛塗装、ローラー塗装、スプレー塗装、ロールコーター、フローコーター等、種々の方法を用いて塗装することができる。塗付量については、下塗材の形態にもよるが、通常０．０８〜０．８ｋｇ／ｍ２程度である。 Such a primer can be applied using various methods such as brush coating, roller coating, spray coating, roll coater, and flow coater. The coating amount is usually about 0.08 to 0.8 kg / m 2 although it depends on the form of the primer.
本発明の塗料組成物は、上記基材に直接または上記下塗材塗膜を介して塗装することができる。この際、本発明組成物は、脂肪族炭化水素系溶剤で適宜希釈することもできる。塗装方法としては、例えば、刷毛塗装、ローラー塗装、スプレー塗装、ロールコーター、フローコーター等、種々の方法を用いることができる。塗付量は、通常０．１〜０．５ｋｇ／ｍ２程度である。 The coating composition of the present invention can be applied to the substrate directly or via the primer coating film. At this time, the composition of the present invention can be appropriately diluted with an aliphatic hydrocarbon solvent. As the coating method, for example, various methods such as brush coating, roller coating, spray coating, roll coater, and flow coater can be used. The coating amount is usually about 0.1 to 0.5 kg / m 2 .
本発明組成物は、溶剤全体の５０重量％以上が脂肪族炭化水素であるので、旧塗膜を有する基材への塗装にも好適に用いることができる。これは、溶解力の強い溶剤を使用した塗料を再塗装すると、旧塗膜の溶解やリフティング等が発生しやすいのに対し、脂肪族炭化水素が５０％重量以上含有されている場合は、このような現象が発生し難いためである。 Since 50 weight% or more of the whole solvent is an aliphatic hydrocarbon, this invention composition can be used suitably also for the coating to the base material which has an old coating film. This is because, when a paint using a solvent having a strong dissolving power is repainted, the old paint film is likely to be dissolved or lifted, but when aliphatic hydrocarbons are contained in an amount of 50% or more by weight, This is because such a phenomenon hardly occurs.
以下に実施例を示し、本発明の特徴をより明確にする。 Examples are given below to clarify the features of the present invention.
