Description

本発明は酸素ガスハイドレートが分解する時に生成される酸素水、又は酸素を酸素硬化塗料に多量に混合した状態でノズルから噴射することにより、塗装対象物上に形成された塗膜の硬化速度を大幅に短縮した酸素硬化塗料の塗布装置に使用する粉体塗料に関する。   The present invention is a method for curing the coating film formed on the object to be coated by spraying from the nozzle in a state where oxygen water generated when the oxygen gas hydrate is decomposed or oxygen is mixed in a large amount with the oxygen curing coating. The present invention relates to a powder coating material used for an oxygen curing coating material coating apparatus in which

塗装対象物に塗料を噴射して塗装を行う塗布装置(塗布スプレー)は、通常コンプレッサの圧力を利用して塗料を噴射している。しかし、コンプレッサを使用する限り塗布装置の小型化、低コスト化には限界がある。
また、塗料は樹脂と顔料とからなっており、樹脂には様々な種類のものが存在するが、塗装対象物に塗布された塗膜が空気中の酸素と反応して硬化する酸素硬化塗料が知られている(特許文献1乃至3等)。
酸素硬化塗料は、酸素と反応して硬化するが、塗布対象物に塗布された塗膜の表面から空気中の酸素を吸収して硬化するために塗膜内部まで十分に硬化するのに要する時間が長期化し、最終的に得られる塗膜の硬化状態、硬度が十分なものではなかった。
2. Description of the Related Art A coating apparatus (coating spray) that performs coating by spraying paint on a coating object normally sprays paint using the pressure of a compressor. However, as long as a compressor is used, there is a limit to reducing the size and cost of the coating apparatus.
In addition, paints consist of resins and pigments, and there are various types of resins. However, there is an oxygen-curing paint that cures when the coating applied to the object to be coated reacts with oxygen in the air. Known (Patent Documents 1 to 3 etc.).
Oxygen curable paint cures by reacting with oxygen, but it takes time to fully cure to the inside of the coating film to absorb and cure oxygen in the air from the surface of the coating film applied to the application object However, the cured state and hardness of the finally obtained coating film were not sufficient.

以上のように従来の酸素硬化塗料にあっては、空気中の酸素と接触する塗膜表面から徐々に硬化が進行してゆくために内部まで硬化するのに長い時間を要し、硬化後においても塗膜内部の硬度が不十分となることがあった。
本発明では、水性、油性に関係なく、酸素硬化塗料をノズルから噴射して対象物に塗布する前の段階で十分な量の酸素を塗料中に混合することにより、塗膜の硬化速度を塗膜の内部に至るまで大幅に速め、しかも硬化後における硬度をも十分に高めることができる粉体塗料を提供することを目的としている。
As described above, in the conventional oxygen curing paint, it takes a long time to cure to the inside because the curing gradually proceeds from the surface of the coating film that comes into contact with oxygen in the air. Also, the hardness inside the coating film may be insufficient.
In the present invention, regardless of whether it is aqueous or oily, a sufficient amount of oxygen is mixed in the paint before the oxygen-cured paint is sprayed from the nozzle and applied to the object, so that the curing speed of the coating film can be applied. An object of the present invention is to provide a powder coating material that can be accelerated to the inside of the film and that can sufficiently increase the hardness after curing.

上記の目的を達成するために請求項1の発明に係る粉体塗料は、酸素ガスハイドレートに対して酸素硬化塗料を添加した構成を備えていることを特徴とする。   In order to achieve the above object, the powder coating material according to the invention of claim 1 is characterized in that it has a structure in which an oxygen-curing coating material is added to oxygen gas hydrate.

請求項2の発明に係る粉体塗料は、前記酸素硬化塗料を予め添加した前記酸素ガスハイドレートを粉体状にしたことを特徴とする。
請求項3の発明に係る粉体塗料は、粉体状にした前記酸素ガスハイドレートに前記酸素硬化塗料を添加したことを特徴とする。
The powder coating material according to the invention of claim 2 is characterized in that the oxygen gas hydrate to which the oxygen curable coating material is added in advance is powdered.
The powder paint according to the invention of claim 3 is characterized in that the oxygen-cured paint is added to the powdered oxygen gas hydrate.

本発明では、酸素硬化塗料の塗布装置により噴射される酸素硬化塗料中に、予め酸素ハイドレートの分解により生成される酸素、或いは酸素を溶存した酸素水を混合し、噴射された塗料が硬化するのに要する時間を大幅に短縮するようにした。
即ち、水性の酸素硬化塗料の場合、酸素ハイドレートの分解槽内が高圧であることから、酸素ハイドレートから生成される水には高濃度の酸素が溶存している。この酸素溶存水(酸素水)が水性の酸素硬化塗料と混ざり、噴射される。また、油性の酸素硬化塗料の場合は、酸素ハイドレートから生成された高圧の酸素を利用して塗料を噴射させる。いずれの場合も、酸素硬化塗装液中に多量の酸素が取り込まれるため、硬化速度が高まり、高硬度の塗膜が得られる。また、いずれも酸素ハイドレート分解槽内の圧力を利用することができるので、コンプレッサも不要となる。
In the present invention, oxygen generated by the decomposition of oxygen hydrate or oxygen water in which oxygen is dissolved is mixed in advance into the oxygen curable paint sprayed by the oxygen curable paint coating apparatus, and the sprayed paint is cured. The time required for this has been greatly reduced.
That is, in the case of a water-based oxygen-curing paint, since the inside of the oxygen hydrate decomposition tank is at a high pressure, a high concentration of oxygen is dissolved in the water produced from the oxygen hydrate. This oxygen-dissolved water (oxygen water) is mixed with an aqueous oxygen-curing paint and sprayed. In the case of an oil-based oxygen-curing paint, the paint is sprayed using high-pressure oxygen generated from oxygen hydrate. In either case, since a large amount of oxygen is taken into the oxygen-curing coating liquid, the curing speed is increased and a high-hardness coating film is obtained. Moreover, since the pressure in an oxygen hydrate decomposition tank can be utilized in any case, a compressor is not required.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
1 (a) and 1 (b) are diagrams showing the principle of an oxygen curing paint coating apparatus according to an embodiment of the present invention, respectively, (a) is a configuration example of an aqueous oxygen curing paint coating apparatus, (B) is an example of a structure of the coating device for oil-based oxygen hardening paints.
The coating apparatus 1 shown in FIG. 1 (a) is for an aqueous oxygen curable coating, and a large amount is obtained by decomposing it by applying heat to the oxygen gas hydrate 3 which is an ice-like substance in which oxygen molecules and water molecules are combined. The hydrate decomposition tank 2 that generates oxygen water 5 and oxygen 6 in which oxygen is dissolved, the water supply pipe 10 that conveys the oxygen water 5 generated by the hydrate decomposition tank 2 to the outside of the tank, and the water supply pipe 10 In the oxygen water / paint mixing unit 15 for mixing the oxygen water 5 to be mixed into the water-based oxygen curable paint 16 supplied from a paint tank (not shown) to generate the oxygen water mixed paint 21, And a nozzle (injecting unit) 20 for injecting the generated oxygen water mixed paint 21.

ハイドレート分解槽2は、内部に網2aを備え、網2a上に酸素ガスハイドレート3を載置する構成を備えている。網2a上の酸素ガスハイドレートが加熱(常温下に置かれることを含む)されることにより分解すると、酸素水5は網2aの下方に位置する槽底部に溜まり、酸素6は槽の上方に溜まる。
水性の酸素硬化塗料16を取り扱う塗布装置1の場合は、図1(a)のように、ハイドレート分解槽2内の高圧を利用して酸素濃度の高い酸素水5が給水管10に供給される。次いで、給水管10の途中に配置された酸素水・塗料混合部15にて水性の酸素硬化塗料16に対して酸素濃度の高い酸素水5が混合されて、最後にノズル20から塗装対象物に対して噴射される。この装置構成によれば、ハイドレート分解槽2内の内圧を利用して酸素水5を圧送するため、コンプレッサ等の付属装置は必要とせず、装置の小型化、簡素化、低コスト化を実現できる。
The hydrate decomposition tank 2 includes a net 2a inside, and has a configuration in which an oxygen gas hydrate 3 is placed on the net 2a. When the oxygen gas hydrate on the net 2a is decomposed by heating (including being placed at room temperature), the oxygen water 5 accumulates at the bottom of the tank located below the net 2a, and the oxygen 6 is above the tank. Accumulate.
In the case of the coating apparatus 1 that handles the water-based oxygen curable coating 16, as shown in FIG. 1A, oxygen water 5 having a high oxygen concentration is supplied to the water supply pipe 10 by using the high pressure in the hydrate decomposition tank 2. The Next, oxygen water 5 having a high oxygen concentration is mixed with the water-based oxygen-curing paint 16 in the oxygen water / paint mixing unit 15 disposed in the middle of the water supply pipe 10, and finally, the nozzle 20 applies the object to the coating object. It is injected against. According to this device configuration, the oxygen water 5 is pumped using the internal pressure in the hydrate decomposition tank 2, so that no additional device such as a compressor is required, and the device is downsized, simplified, and reduced in cost. it can.

このように酸素ガスハイドレートの分解により生成された酸素水5は噴射前に水性の酸素硬化塗料16と混合され、塗装対象物に塗装される。この酸素水5の中には多量の酸素が溶存しており、塗装対象物に塗布されることにより形成された塗膜は、塗料自体に含有される多量の酸素により早期に硬化する。
なお、水性の酸素硬化塗料の一例としては、アルキド樹脂の乳化物をバインダとして用いた水性アルキド樹脂塗料を挙げることができる。
Thus, the oxygen water 5 produced | generated by decomposition | disassembly of oxygen gas hydrate is mixed with the aqueous | water-based oxygen hardening coating material 16 before injection, and is coated by the coating object. A large amount of oxygen is dissolved in the oxygen water 5, and the coating film formed by being applied to the object to be coated is quickly cured by the large amount of oxygen contained in the paint itself.
An example of the water-based oxygen curable paint is an aqueous alkyd resin paint using an alkyd resin emulsion as a binder.

次に、図1(b)に示した塗布装置1は、油性の酸素硬化塗料用であり、酸素分子と水分子が結合した氷状物質である酸素ガスハイドレート3に熱を加えて分解することにより酸素水5と酸素6を生成するハイドレート分解槽2と、ハイドレート分解槽2により生成された酸素6を槽外に搬送する酸素供給管30と、酸素供給管30により搬送される酸素6に図示しない塗料タンクから供給される酸素硬化塗料36を混合して酸素混合塗料41を生成する酸素・塗料混合部35と、酸素・塗料混合部35において生成された酸素混合塗料41を噴射するノズル(噴射部)40と、を備えている。
油性の酸素硬化塗料36を取り扱う塗布装置1の場合は、図1(b)のようにハイドレート分解槽内の高圧を利用して酸素が酸素供給管30に搬送される。次いで、酸素供給管30の途中に配置された酸素・塗料混合部35にて油性の酸素硬化塗料36に対して酸素6が混合されて、最後にノズル40から塗装対象物に対して噴射される。この装置構成によれば、ハイドレート分解槽2内の内圧を利用して酸素を圧送するため、コンプレッサの付属装置は必要とせず、装置の小型化、簡素化、低コスト化を実現できる。
Next, the coating apparatus 1 shown in FIG. 1B is for an oil-based oxygen-curing coating, and decomposes by applying heat to the oxygen gas hydrate 3 that is an ice-like substance in which oxygen molecules and water molecules are combined. Thus, the hydrate decomposition tank 2 that generates oxygen water 5 and oxygen 6, the oxygen supply pipe 30 that transfers the oxygen 6 generated by the hydrate decomposition tank 2 to the outside of the tank, and the oxygen that is transferred by the oxygen supply pipe 30 6 is mixed with an oxygen-curing paint 36 supplied from a paint tank (not shown) to generate an oxygen-mixed paint 41, and the oxygen-mixed paint 41 generated in the oxygen / paint-mixing section 35 is sprayed. Nozzle (injection unit) 40.
In the case of the coating apparatus 1 that handles the oil-based oxygen curable coating 36, oxygen is conveyed to the oxygen supply pipe 30 using the high pressure in the hydrate decomposition tank as shown in FIG. Next, oxygen 6 is mixed with the oil-based oxygen-cured paint 36 in the oxygen / paint mixing unit 35 disposed in the middle of the oxygen supply pipe 30 and finally injected from the nozzle 40 onto the object to be coated. . According to this apparatus configuration, oxygen is pumped by utilizing the internal pressure in the hydrate decomposition tank 2, so that no compressor attachment device is required, and the apparatus can be reduced in size, simplified, and reduced in cost.

このように酸素ガスハイドレートの分解により生成された酸素6は噴射前に油性の酸素硬化塗料36と混合され、塗装対象物に塗装される。塗装後の塗膜中には多量の酸素が含まれており、塗装対象物に塗布されることにより形成された塗膜は、塗料自体に含有される多量の酸素により早期に硬化する。
油性の酸素硬化塗料としては、アルキド樹脂をバインダとして用いたアルキド樹脂塗料を挙げることができる。
Thus, the oxygen 6 generated by the decomposition of the oxygen gas hydrate is mixed with the oil-based oxygen-curing paint 36 before being sprayed and applied to the object to be coated. A large amount of oxygen is contained in the coated film, and the coated film formed by being applied to the object to be coated is quickly cured by the large amount of oxygen contained in the coating itself.
Examples of the oil-based oxygen curable paint include an alkyd resin paint using an alkyd resin as a binder.

次に、図2は本発明の酸素硬化塗料の塗布装置の一例としてのスプレーガンの構成を説明する図である。
このスプレーガン50は、基体51と、基体51の内部に設けた空所である混合部52と、混合部から前方へ延びる流路53と、流路53と連通し基体51の先端で開放した塗料噴射用のノズル部54と、基体51の上面に沿って長手方向へ進退自在に支持された第1のスライド機構Aと、基体51の下面に沿って長手方向へ進退自在に支持された第2のスライド機構Bと、各スライド機構A、 Bを作動させるレバーCと、水性の酸素硬化塗料61を収容し且つ基体51によって支持された流体カップDと、を備えている。
Next, FIG. 2 is a view for explaining the configuration of a spray gun as an example of an oxygen curing paint coating apparatus according to the present invention.
The spray gun 50 is opened at the tip of the base 51, the base 51, a mixing portion 52 that is a space provided inside the base 51, a flow channel 53 that extends forward from the mixing portion, and the flow channel 53. The nozzle 54 for spraying paint, the first slide mechanism A supported so as to be movable back and forth in the longitudinal direction along the upper surface of the base 51, and the first slide mechanism A supported so as to be able to advance and retract in the longitudinal direction along the lower surface of the base 51. 2 slide mechanism B, a lever C for operating each slide mechanism A, B, and a fluid cup D that contains an aqueous oxygen-curing paint 61 and supported by a base 51.

第1のスライド機構Aは、混合部52の上部開口52aと選択的に連通可能な塗料導入孔56を備え且つ矢印で示す長手方向へ進退可能な第1のスライダ55と、第1のスライダ55を塗料導入孔56と混合部52とが連通しない閉止方向(図面右方向)へ付勢する第1の弾性部材57と、を備える。第1の弾性部材57は一端部を基体適所に固定されると共に他端部を第1のスライダ55に固定されることにより、第1のスライダ55を常時右方(閉止方向)へ付勢している。
実線で図示した閉止状態においては、塗料導入孔56と混合部52との間は非連通状態にある。
The first slide mechanism A includes a first slider 55 that includes a paint introduction hole 56 that can selectively communicate with the upper opening 52a of the mixing unit 52, and that can advance and retreat in the longitudinal direction indicated by an arrow. And a first elastic member 57 that urges the coating material introduction hole 56 and the mixing portion 52 in the closing direction (right direction in the drawing). One end of the first elastic member 57 is fixed at a suitable position on the base and the other end is fixed to the first slider 55, thereby constantly urging the first slider 55 rightward (in the closing direction). ing.
In the closed state illustrated by the solid line, the paint introduction hole 56 and the mixing portion 52 are not in communication.

第2のスライド機構Bは、混合部52の下部開口52bと選択的に連通可能な酸素水導入孔66を備え且つ矢印で示す長手方向へ進退可能な第2のスライダ65と、第2のスライダ65を酸素水導入孔66と混合部52とが連通しない閉止方向(図面左方向)へ付勢する第2の弾性部材67と、を備える。第2の弾性部材67は一端部を基体適所に固定されると共に他端部を第2のスライダ65に固定されることにより、第2のスライダ65を常時左方(閉止方向)へ付勢している。   The second slide mechanism B includes an oxygen water introduction hole 66 that can selectively communicate with the lower opening 52b of the mixing unit 52, and a second slider 65 that can advance and retreat in the longitudinal direction indicated by an arrow. A second elastic member 67 that urges 65 in the closing direction (left direction in the drawing) in which the oxygen water introduction hole 66 and the mixing portion 52 do not communicate with each other. One end of the second elastic member 67 is fixed at an appropriate position of the base and the other end is fixed to the second slider 65, thereby constantly urging the second slider 65 to the left (in the closing direction). ing.

第2のスライド機構Bの下方には図1に示した如きハイドレート分解槽2が連設されており、ハイドレート分解槽2内で酸素ハイドレートを分解することにより生成された高圧の酸素水5が酸素水供給経路70から酸素水導入孔66へ供給される。
実線で示した待機状態では第2のスライダ65が第2の弾性部材67によって図面左方へ付勢されているため、酸素水供給経路70と酸素水導入孔66とは非連通の状態にあり、その結果酸素水供給経路(給水管)70と混合部52との間も非連通状態にある。
破線で示すように弾性部材67による付勢力に抗して第2のスライダ65が図面右方(開放方向)へスライドすると、酸素水導入孔66が酸素水供給経路70と混合部52との間を連通させるため、混合部52内に酸素水5が供給される。
A hydrate decomposition tank 2 as shown in FIG. 1 is connected below the second slide mechanism B, and high-pressure oxygen water generated by decomposing oxygen hydrate in the hydrate decomposition tank 2. 5 is supplied from the oxygen water supply path 70 to the oxygen water introduction hole 66.
In the standby state indicated by the solid line, since the second slider 65 is urged to the left by the second elastic member 67, the oxygen water supply path 70 and the oxygen water introduction hole 66 are not in communication. As a result, the oxygen water supply path (water supply pipe) 70 and the mixing section 52 are also in a non-communication state.
As shown by the broken line, when the second slider 65 slides to the right (opening direction) against the urging force of the elastic member 67, the oxygen water introduction hole 66 is located between the oxygen water supply path 70 and the mixing portion 52. Is connected to the mixing section 52.

流体カップDは、水性の酸素硬化塗料61を収容したカップ本体60と、塗料導入孔56と混合部52との非連通時にスライダ55上面により閉止される流体カップの塗料吐出口62と、を備えている。実線で示した待機状態(閉止状態)では第1のスライダ55によって塗料吐出口62は閉止された状態にあるが、破線で示したように第1のスライダ55が第2の弾性部材57の付勢力に抗してノズル側へスライドした場合には塗料導入孔56を介して塗料吐出口62と混合部52とが連通した状態となり、混合部52内に水性の酸素硬化塗料61が供給される。   The fluid cup D includes a cup body 60 that contains a water-based oxygen-curing paint 61, and a fluid cup paint discharge port 62 that is closed by the upper surface of the slider 55 when the paint introduction hole 56 and the mixing portion 52 are not in communication. ing. In the standby state (closed state) indicated by the solid line, the paint discharge port 62 is closed by the first slider 55, but the first slider 55 is attached to the second elastic member 57 as indicated by the broken line. When sliding to the nozzle side against the force, the paint discharge port 62 and the mixing part 52 are in communication with each other through the paint introduction hole 56, and the aqueous oxygen-curing paint 61 is supplied into the mixing part 52. .

このように流体カップD内の水性の酸素硬化塗料61が混合部52内に供給される動作と、ハイドレート分解槽2からの酸素水5が混合部52内に供給される動作とがほぼ同時に実施されることにより、混合部52では酸素濃度の高い酸素水5が酸素硬化塗料61に混合された状態となる。この実施形態では、この混合動作はレバーCを操作することにより実現される。
レバーCは、基体51の適所に設けたピン80により実線で示した位置(閉止位置)と破線で示した位置(開放位置)との間を回動自在に支持されると共に、ピン80よりも上部適所から延びる連結部材81によって第1のスライダ55と連結され、更にピン80よりも下部適所から延びる連結部材82によって第2のスライダ65と連結されている。
Thus, the operation in which the aqueous oxygen-curing paint 61 in the fluid cup D is supplied into the mixing unit 52 and the operation in which the oxygen water 5 from the hydrate decomposition tank 2 is supplied into the mixing unit 52 are almost simultaneously performed. As a result, oxygen water 5 having a high oxygen concentration is mixed with the oxygen-curing paint 61 in the mixing unit 52. In this embodiment, this mixing operation is realized by operating the lever C.
The lever C is rotatably supported between a position indicated by a solid line (closed position) and a position indicated by a broken line (open position) by a pin 80 provided at an appropriate position of the base body 51, and moreover than the pin 80. The first slider 55 is connected to a first slider 55 by a connecting member 81 extending from an upper proper position, and is further connected to the second slider 65 by a connecting member 82 extending from a lower proper position rather than the pin 80.

実線で示した閉止位置にあるレバーCを作業者が指等により破線で示した開放位置まで反時計回り方向へ引くことにより、連結部材82を介して第2のスライダ65が前方(ノズル側)へ移動することにより、第1の弾性部材57が縮み、塗料導入孔56が前方へ移動する。その結果、塗料導入孔56が酸素硬化塗料61の流路62と一致し、流体カップD中の酸素硬化塗料61が重力により混合部52へ供給される。
また、レバーCを開放位置に回動させると、連結部材81を介して第1のスライダ55が後方へ移動することにより、第2の弾性部材67が伸びて酸素水導入孔66が後方へ移動して破線で示した連通位置に達する。その結果、酸素水導入孔66が酸素水供給経路70及び下部開口52bと連通し、酸素ハイドレートが分解されたことにより生成された酸素水5が混合部52まで供給される。
When the operator pulls the lever C in the closed position indicated by the solid line counterclockwise with a finger or the like to the open position indicated by the broken line, the second slider 65 is moved forward (nozzle side) via the connecting member 82. , The first elastic member 57 contracts, and the paint introduction hole 56 moves forward. As a result, the paint introduction hole 56 coincides with the flow path 62 of the oxygen curable paint 61, and the oxygen curable paint 61 in the fluid cup D is supplied to the mixing unit 52 by gravity.
Further, when the lever C is rotated to the open position, the first slider 55 moves rearward via the connecting member 81, whereby the second elastic member 67 extends and the oxygen water introduction hole 66 moves rearward. The communication position indicated by the broken line is reached. As a result, the oxygen water introduction hole 66 communicates with the oxygen water supply path 70 and the lower opening 52b, and the oxygen water 5 generated by the decomposition of the oxygen hydrate is supplied to the mixing unit 52.

このようにレバーCを開放方向へ回動させる操作を行うことにより、混合部52内に酸素硬化塗料61と酸素水5が導入して混合され酸素水混合塗料21となってノズル54を介して噴霧される。酸素ガスハイドレートの分解により生成された酸素水5は分解槽2内の圧力を利用して圧送されるため、大型化、高コスト化の原因となるコンプレッサを省略してスプレーガンを構成することができる。そして、塗装対象物に形成された塗膜中には必要十分な量の酸素が混合されているため、塗膜内部に至るまで短時間で硬化することができる。
なお、上記実施形態では、水性の酸素硬化塗料を使用したスプレーガンの構成について説明したが、このスプレーガンの構成は油性の酸素硬化塗料にも流用することができる。即ち、流体カップD内に油性の酸素硬化塗料を収容すると共に、酸素水供給経路(酸素供給管)70に対して分解槽2から供給される高圧の酸素を供給することにより、混合部52内にて酸素硬化塗料を混合するように構成すればよい。
By performing the operation of rotating the lever C in the opening direction in this way, the oxygen curing paint 61 and the oxygen water 5 are introduced and mixed in the mixing portion 52 to become the oxygen water mixed paint 21 through the nozzle 54. Sprayed. Since the oxygen water 5 generated by the decomposition of the oxygen gas hydrate is pumped using the pressure in the decomposition tank 2, a compressor that causes an increase in size and cost is omitted and the spray gun is configured. Can do. And since a necessary and sufficient amount of oxygen is mixed in the coating film formed on the object to be coated, it can be cured in a short time until reaching the inside of the coating film.
In the above-described embodiment, the configuration of the spray gun using the water-based oxygen curable paint has been described. However, the configuration of this spray gun can also be used for the oil-based oxygen curable paint. That is, the oil-based oxygen-cured coating material is accommodated in the fluid cup D, and the high-pressure oxygen supplied from the decomposition tank 2 is supplied to the oxygen water supply path (oxygen supply pipe) 70, so The oxygen-curing paint may be mixed at

以上のように本発明においては、酸素硬化塗料の塗布装置により噴射される酸素硬化塗料中に、予め酸素ハイドレートの分解により生成される酸素、或いは酸素を溶存した酸素水を混合し、噴射された塗料が硬化するのに要する時間を大幅に短縮することが可能となる。
即ち、水性の酸素硬化塗料の場合には酸素ハイドレートの分解槽内が高圧であることから、酸素ハイドレートから生成される水には高濃度の酸素が溶存している。この酸素溶存水(酸素水)が水性の酸素硬化塗料と混ざって噴射される。また、油性の酸素硬化塗料の場合は、酸素ハイドレートから生成された高圧の酸素を利用して塗料を噴射させる。いずれの場合も、酸素硬化塗装液中に多量の酸素が取り込まれるため、硬化速度が高まり、高硬度の塗膜が得られる。また、いずれも酸素ハイドレート分解槽内の圧力を利用することができるので、コンプレッサも不要となる。
As described above, in the present invention, oxygen generated by the decomposition of oxygen hydrate or oxygen water in which oxygen is dissolved is mixed and injected into the oxygen-curing paint sprayed by the oxygen-curing paint coating apparatus. It is possible to greatly reduce the time required for the paint to cure.
That is, in the case of a water-based oxygen curable coating, since the inside of the oxygen hydrate decomposition tank is at a high pressure, a high concentration of oxygen is dissolved in the water produced from the oxygen hydrate. This oxygen-dissolved water (oxygen water) is jetted mixed with an aqueous oxygen-curing paint. In the case of an oil-based oxygen-curing paint, the paint is sprayed using high-pressure oxygen generated from oxygen hydrate. In either case, since a large amount of oxygen is taken into the oxygen-curing coating liquid, the curing speed is increased and a high-hardness coating film is obtained. Moreover, since the pressure in an oxygen hydrate decomposition tank can be utilized in any case, a compressor is not required.

なお、図1、及び図2の各実施形態では、水性の酸素硬化塗料、及び油性の酸素硬化塗料に対して、酸素ガスガイドレートに由来する酸素水、又は酸素を混合する塗布装置の構成を示したが、これ以外にも例えば酸素ガスハイドレートに塗料(樹脂、顔料成分)を予め混合したもの自体を塗料(粉体塗料)として使用することも可能である。即ち、塗料成分を予め添加した酸素ガスハイドレートを細かい粉体状にしておき、この粉体塗料としての酸素ガスハイドレートを塗布対象物に塗布することにより、塗装対象物に付着した後で溶解して固化するように構成してもよい。   In each embodiment of FIG. 1 and FIG. 2, the configuration of a coating apparatus that mixes oxygen water derived from an oxygen gas guide rate or oxygen with respect to an aqueous oxygen curable paint and an oily oxygen curable paint. In addition to the above, for example, a mixture of oxygen gas hydrate and a paint (resin, pigment component) previously mixed can be used as a paint (powder paint). In other words, the oxygen gas hydrate to which the paint component has been added in advance is made into a fine powder, and the oxygen gas hydrate as a powder coating is applied to the object to be coated, so that it dissolves after adhering to the object to be coated. And may be configured to solidify.
