。During molding of the thermosetting resin molding material, the mold release agent contained in the thermosetting resin molding material oozes out onto the mold surface and exhibits a mold release effect. If such molding is repeated, the mold release properties of the molded product will deteriorate significantly, and the surface of the molded product will become rough due to the transfer of the surface of the oxidation-degraded layer of the mold release agent (the surface is not as smooth as the mold). This causes problems such as lack of gloss on the surface of the molded product. The cause of this is that the above mold release agent is sequentially layered on the mold surface due to repeated molding,
This is thought to be due to gradual oxidation deterioration and formation of a hard oxidation-degraded layer of the mold release agent. Once such an oxidation-degraded layer of the mold release agent is formed on the mold surface, when the thermosetting resin molding material is subsequently molded, the mold release agent that oozes out from the molding material is deposited on the mold surface. Instead, it acts on the oxidation-degraded layer of the above mold release agent, making it impossible to exhibit a sufficient mold release effect. In order to solve such problems, conventionally, a thermosetting melamine resin molding material is placed in the mold and cured, and the oxidation-degraded layer of the release agent on the surface of the mold is integrated with the molded product. The surface of the mold is cleaned by removing the molded product with the oxidation-degraded layer integrated therefrom from the mold. In this case, formalin is produced as a condensation product of the thermosetting melamine resin molding material, causing odor and the like, which deteriorates the working environment and causes a decrease in cleaning workability.

っている。As mentioned above, when cleaning the mold surface using a thermosetting melamine resin molding material, the working environment may deteriorate due to odors, etc., so unvulcanized rubber compounds are used instead of the thermosetting melamine resin. It is used in place of the molding material and is vulcanized in the above mold to form a vulcanized rubber, and when the vulcanized rubber is formed, the oxidized deterioration layer of the mold release agent on the surface of the mold is integrated with the vulcanized rubber, and then A method of cleaning the surface of the mold by removing the vulcanized rubber from the mold has been proposed and has been implemented in some cases. In this case, an amino alcohol represented by the general formula % is added to improve cleaning performance. However, this amino alcohol evaporates during vulcanization of the unvulcanized rubber compound and causes odor, so even with this method, the working environment deteriorates and the cleaning workability deteriorates.

) That is, as a result of a series of studies conducted by the present inventors on the cleaning effect on molds such as thermosetting resin molds,
Not only does the glycol ether represented by the above general formula (1) have excellent compatibility with the unvulcanized rubber dough, but when it is mixed into the rubber dough, it is contaminated by the oxidation-degraded layer of the mold release agent. When vulcanization is carried out in a mold that is vulcanized, contaminants on the mold surface migrate into the vulcanized rubber, so the mold surface can be easily cleaned by removing the vulcanized rubber from the mold. This invention was achieved by discovering that In this case, when the unvulcanized rubber is vulcanized in the mold, there is no odor such as formalin odor or amine odor, and there is no problem of deterioration of the working environment.

洗浄作業性を低下させる傾向がみられるからである。The above-mentioned glycol ethers become a mold cleaning composition by mixing with the above-mentioned unvulcanized rubber dough. In this case, the glycol ethers are usually blended in an amount of 10 to 60 parts per 100 parts of the unvulcanized rubber dough. Preferably 1
It is about 5 to 25 parts. The boiling point of the glycol ethers is preferably about 130 to 250°C. That is, mold molding is usually performed at 150 to 185°C, and the boiling point of the glycol ether is 13
If it is below 0℃, evaporation during cleaning will be significant, which may lead to deterioration of the cleaning work environment;
If the temperature exceeds 50°C, it will be difficult to evaporate and remain in the vulcanized rubber, and the strength of the vulcanized rubber will weaken when removed from the mold, resulting in deformation, etc., so it will not be possible to release it from the mold surface. It becomes difficult to fully separate the oxidation-degraded layer of the agent,
This is because there is a tendency to reduce cleaning workability.

In this case, the amount of reinforcing agent used is preferably set at 10 to 50 parts per 100 parts of the unvulcanized rubber fabric. Furthermore, as mentioned above, it is also possible to incorporate a mold release agent. Examples of the above mold release agent include stearic acid, zinc stearate, carnauba wax, monk wax, and stearyl ethylene diamide. It is possible to mix 1 to 10 parts of these to 100 parts of unvulcanized rubber dough.
