本発明はプラスチック溶射塗装、特にェポキシ樹脂など
の熱硬化性プラスチック粉体の溶射塗装用溶射装置に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermal spraying apparatus for thermal spray coating of plastics, particularly for thermal spray coating of thermosetting plastic powders such as epoxy resins.
粉体塗装法の一つであるプラスチック溶射塗装は、静電
塗装法や流動浸債法などのような加熱炉を用いる粉体塗
装法とは異なり、塗装装置が簡便であること、極めて厚
膜が得られること、既設の構造物への塗装が可能である
こと、などの特徴を有する。Plastic thermal spray coating, which is one of the powder coating methods, differs from powder coating methods that use heating furnaces, such as electrostatic coating and fluidized bonding, because the coating equipment is simple and the coating is extremely thick. It has the following characteristics: it can be used to paint existing structures, and it can be applied to existing structures.

態ならびに特性としたものである。この中でェポキシ樹
脂は、機械的特性、電気的特性、熱的特性薬品特性等に
優れていること、および硬化反応の速度や形態の自由度
が大きいこと等の多くの特長を有する。The powder coating used for this purpose is made by thermally spraying powders of thermoplastic resins such as nylon, polyethylene, and vinyl chloride and powders of thermosetting resins such as epoxy resins. be. Among these, epoxy resin has many features such as excellent mechanical properties, electrical properties, thermal properties, chemical properties, etc., and a high degree of freedom in curing reaction speed and form.
そのため、防食用粉体塗料として、近年、多量に使用さ

には被塗物に与えられる予熱と溶射火炎の頚射熱とだけ
で完了させねばならないものである。Therefore, in recent years, it has been used in large quantities as an anticorrosive powder coating. When this epoxy resin is blended in such a way that the curing reaction rate is particularly fast and applied to total spray coating, it can be applied to the so-called "post-heating" process, which involves heating at a predetermined temperature for a predetermined time to complete the curing reaction, which is done in a general powder coating process. ” process can be omitted. Therefore, there are no restrictions on the shape of the object to be coated, and existing structures can also be powder coated. Epoxy resins have therefore been widely used as heavy duty anti-corrosion linings and electrically insulating linings. Thermal spray coating using epoxy resin powder without a "post-heating" process is one in which the curing reaction is completed by heating the epoxy resin powder at a predetermined temperature for a predetermined time, as described above. This process must be completed using only the preheating applied to the coating and the head heat from the spray flame.
したがって、材料となるェポキシ樹脂は、極めて硬化速

スプレーされた樹脂が彼塗物表面に付着するまでにすで
に約８０％の硬化反応を起こしている。Therefore, the epoxy resin used as the material needs to be a composition with an extremely slow curing rate. The gelation time, which is one of the indicators of curing speed, is, for example, at a temperature of 110q
It should be something like 2 minutes and 3 legs at o, 1 minute at 150 qo, and 2 gensuna at 200 o'clock. In thermal spray coating using powder of such a fast-curing composition,
By the time the sprayed resin adheres to the surface of the coating, about 80% of the curing reaction has already occurred.

。Immediately after it adheres to the surface of the object to be coated, it gels almost instantaneously, and then the curing reaction is completed. Therefore, the period during which the resin is in a fluid state on the surface of the object to be coated is short, and the range of conditions under which a smooth coating can be obtained is extremely narrow. However, since the resin portion that is directly hit by the spray flame is sufficiently heated, it is possible to heat and melt the resin, which has increased in viscosity due to the progress of the curing reaction, until it becomes a smooth coating film. On the other hand, the overspray mist and so-called particles scattered around the blast flame are also undergoing a curing reaction. However, since sufficient competitive heat cannot be obtained from these particles, even if they adhere to the object to be coated, they do not melt but gel, and then harden. Therefore, not only is it impossible to obtain a smooth coating film, but it also causes coating film defects such as inclusion of air bubbles and pinholes. An object of the present invention is to provide a thermal spraying apparatus that forms a smooth sprayed coating film.

Still another object of the present invention is to provide a thermal spray coating particularly suitable for thermal spray coating of thermosetting plastic powder such as epoxy resin. The present invention will be described in detail below based on embodiments and with reference to the drawings.

端３０から噴射される。As shown in FIGS. 1 and 2, a thermal spraying apparatus 1 of the present invention
has a supply means 2, a thermal spray nozzle 3, and an annular cover 5. The supply means 2 is made up of a plurality of hoses, for example, and is connected to the rear end of the thermal spray nozzle 3. These hoses supply flame gas, paint powder, cooling air, etc., such as propane gas and oxygen gas, to the thermal spray nozzle 3, respectively. An annular cover 5 is attached to the nozzle 3 via a support frame 4. This support rack 4 surrounds the vicinity of the tip of the thermal spray nozzle 3 at one end 41 thereof. The pond end 42 of this support rack 4
An annular cover 5 is fixed along its periphery. This annular cover 5 causes a "Coanda effect" in the fluid near its surface. This cover 5 is desirably made of a hollow pipe or the like, and has a slit 5.
0 is Sekiguchi colle. The cover 5 also has an exhaust port 51 through which it is connected to a suction means such as a suction pump (not shown). The flame gases supplied to the nozzle 3 via the supply means 2 are mixed there, become a thermal spray flame 31, and are injected from the nozzle tip 30.

る。The material powder is injected from a nozzle tip 30 into a traverse flame 31 together with cooling air to form a thermal spray 32 . This thermal spray 32 receives neck radiation heat from the thermal spray flame 31 and is heated. The material powder of the heated thermal spray spray 32 is fused and sprayed toward the object 6 to be coated outside the annular cover. The coating material 6 is heated to a predetermined temperature. The molten material powder adheres to the surface and forms a coating film 7. The above blast spray 32
Overspray mist 33 is scattered around this thermal spray spray 32 while it is being sprayed toward the outside of the apparatus 1 .

塗装の一実施例を示す。The traveling direction of these overspray mist 33 is deflected by the "Coanda effect" of the annular cover 5. The overspray mist whose traveling direction is bent is scattered radially from the tip of the device 1 in parallel to the object 6 to be coated, and does not collide with the object 6 to be coated. In particular, when the air inside and outside the annular cover is constantly sucked by the suction means through the slit 50 and the exhaust port 51, the overspray mist scattered along the surface of the annular cover is absorbed into the cover along with the suction air. /or be captured by suction means. Therefore, the overspray mist does not adhere to the surface of the annular cover 5, and the effect of changing the traveling direction of the overspray mist is increased.
Next, an example of thermal spray coating of epoxy resin powder using the spraying apparatus of the present invention will be described.
