（技術分野）
本発明は一般的には硬化性の液状物を用いて物の表面を
被覆ｊる方法に関し、特に、硬化性の樹脂材料を用いて
トンネル覆工用の移動式型枠のような型枠の鋼製表面板
を被覆するのに適した被覆方法に関する。Detailed Description of the Invention (Technical Field) The present invention generally relates to a method of coating the surface of an object using a curable liquid material, and particularly relates to a method of coating the surface of an object using a curable resin material. The present invention relates to a coating method suitable for coating steel face plates of formwork, such as mobile formwork.

ｉｌｉし易いという欠点がある。(Prior art) Conventionally, the steel surface plate of the movable formwork for tunnel lining was
Coatings such as epoxy resins are applied for purposes such as rust prevention and surface protection, and when concrete lining is placed in tunnel construction, formwork is used by coating this coating with a release agent such as mineral oil. Ta. This coating is advantageous in that it is smooth enough to give a gloss to the cast concrete surface. However, this coating has the disadvantage that it is easily abraded or irritated by the friction and impact received from the sand and gravel contained in the concrete.
（発明の目的）
したがって、本発明の目的は、コンクリート面に光沢を
与えるに十分な平滑さを失うことなしに、コンクリート

抗性を高め、摩滅または剥落し難くすることにある。OBJECTS OF THE INVENTION It is therefore an object of the present invention to increase the resistance of the coating to friction and impact from sand and gravel in concrete, without losing sufficient smoothness to impart gloss to the concrete surface; The purpose is to make it difficult to wear out or peel off.

加熱して硬化させることを特徴とする。(Structure and Effects of the Invention) A method for coating a mold face plate according to the present invention includes spraying a liquid mixture of a urethane-based or epoxy-based liquid uncured resin and ceramic fine particles onto a mold face plate, and allowing the mixture to cool at room temperature. Alternatively, it is characterized by being cured by heating.

て再被覆までの使用回数を確実に伸ばすことができる。According to the present invention, since the coating on the face plate is reinforced with ceramic fine particles, resistance to friction and impact received from sand and gravel in concrete is increased, and the mixture is coated on the face plate while in a liquid state. Since it is sprayed at high pressure, there are almost no ceramic fine particles with a high specific gravity on the surface of the coating, and the surface of the coating maintains the same smoothness as if no ceramic fine particles were mixed in. Therefore, according to the formwork whose face plate is coated by the method of the present invention, the concrete surface has a gloss, and the formwork can be used repeatedly without the coating fading or peeling off, and can be re-coated. You can definitely increase the number of times you can use it.

In addition, as epoxy-based liquid resins, bisphenol A epoxy resin, fatty epoxy resin,
A novolak type epoxy resin or the like is used as the main ingredient, and a polyamide-based or single amine-based curing agent can be used as the curing agent.

。The ceramic fine particles are ceramics such as alumina, silicon carbide, silicon nitride, zirconia, titanium oxide, magnesia hydroxide, etc., and have a particle size of 1 to 30 microns, and the amount mixed is 2 to 30 microns of the total weight of the liquid resin. Preferably, the weight is 15%. If the amount is less than 2%, the desired reinforcement hardening cannot be obtained in the coating, and if the amount is more than 15%, the desired smoothness cannot be obtained on the surface of the coating.

を促進することができるので、作業能率上有利である。For coating, first, if two-component resins are used, they are weighed and mixed, and a predetermined amount of ceramic fine particles are also weighed and mixed. Next, a spraying device such as a spray gun is used to spray a uniform thickness onto the surface of the mold face plate which has been cleaned in advance. When using thermosetting resin, heating is essential, so transfer it to a furnace and heat it to 100 to 18
The mixture sprayed onto the face plate is cured by heating at a temperature of 00C to complete the coating. If a non-thermosetting resin is used, heating is not necessary and it can be cured at room temperature, but curing at a temperature of 60 to 70'C can accelerate curing, which is advantageous in terms of work efficiency. It is.

とはない。Note: After the mixture of liquid resin and ceramic particles is sprayed onto the face plate at room temperature without heating, it continues to flow as a liquid at room temperature or until it is heated and hardened. Because the blown ceramic particles tend to reach deep into the layer of the blown mixture due to their specific gravity, the ceramic particles are not exposed on the surface of the hardened coating, and therefore the ceramic particles are not exposed to the surface of the hardened coating. The smoothness of the coated surface is not impaired by the fine particles.

When a micron-thick coating was subjected to an abrasion test using a taper set abrasion tester, it was revealed that the durable abrasion value was more than three times greater than that of a coating that did not contain alumina ceramic fine particles.
