。Exit> Conventional technology In the case of a drain pan made of expanded polystyrene (styrofoam), it was developed in the 1970s to increase strength and prevent water leakage.
As disclosed in Japanese Patent No. 32356, the inner surface is covered with a thin styrene sheet, and currently fan casings for sirocco fans are molded only from expanded polystyrene without using a styrene sheet. be.

っていた。(c) Problems to be solved by the invention When an air conditioner is used in the living room, bedroom, or office of a general household, no particular problem arises, but when used in a kitchen or a machine cutting factory, it Steam of edible fats and oils in the room,
Styrofoam sheets and expanded polystyrene are eroded by the mist, cannibal oil vapor in machine cutting factories, and solvent vapor during parts cleaning, causing problems such as melting and cracking, and especially in the case of drain pans, air Drain water generated in the evaporator during cooling operation of the conditioner contains oil and solvents, which can corrode the evaporator and cause water leaks.

（製品組み込み時、運搬時等）で種々の問題がある。Therefore, in order to solve this problem, attempts were made to form a film on the surface of expanded polystyrene by coating it with epoxy resin, but when coating with epoxy resin, it was difficult to coat only the horizontal flat parts. If there is, the coating thickness can be made uniform and there is no particular problem. However, when coating a vertical surface or a sloped surface, the epoxy resin drips, causing extremely thick parts and thin parts. This causes various problems in actual use (during product integration, transportation, etc.), such as clogging of the drain port and lack of strength due to thin vertical walls.

ある。(e) Function It is necessary to select a resin material for the film that covers the surface of the polystyrene foam molding that has excellent chemical resistance (not being attacked by oil or solvents) and that does not corrode the polystyrene foam.
この点を充分に考慮した結果、皮膜の樹脂材料として無
溶剤型エポキシ系樹脂が最も適している。As a result of careful consideration of this point, a solvent-free epoxy resin is most suitable as the resin material for the film.

により行なわれ、シキソトロビー付与剤の作用により、
容易に且つ均一の厚みの皮膜が形成される。The film can be formed by molding a drain pan out of expanded polystyrene, and then applying a solvent-free epoxy resin solution containing a xyxotrobe imparting agent to the surface, or immersing the drain pan in this resin solution to allow adhesion. , by drying, and by the action of a xixotrobe imparting agent,
A film of uniform thickness is easily formed.

上述した皮膜で覆うようにしても良い。Coating with such a film eliminates the need for the styrene sheet conventionally used in drain pans, but if a styrene sheet is used to further increase strength and water resistance, the surface of the styrene sheet integrally welded with expanded polystyrene may be used as described above. It may be covered with a film.

。The table below shows the case where a solvent-free epoxy resin containing 3 wt% of a xyxotrobe imparting agent and a solvent-free epoxy resin containing no xyxotrobe imparting agent are applied with a brush to the inside of the drain pan (6) as shown in Figure 2. The figure shows the wall thickness dimensions of the film (10) in each part of
- The maximum wall thickness is 1.50T[Im, whereas the minimum wall thickness of the resin without the xyxotrobi imparting agent is 0.0711
1 [11-Maximum wall thickness 2.30 TIl [Il] There is a difference in the wall thickness and the amount of resin used is larger with the resin without adding the xyxotrobe imparting agent, especially on the vertical surface. Since the wall thickness is small, holes may easily be formed in the coating (10) due to external stress.

The resin has fluidity and can be applied uniformly and easily, and once it has been applied to the surface of the foamed polystyrene molded product, it has the property of not dripping until the resin dries or hardens. The coating on the inclined surface can be made to have substantially the same thickness as the coating on the bottom surface and to have a uniform thickness.
