Abstract

PURPOSE:To provide a mold cleaning composition made of polymeric materials as a main component containing 1,0-tolylbiguanide, which cleans molding dies with excellent cleaning effect, and to obtain a molded piece having excellent appearance. CONSTITUTION:A mold cleaning composition is made of polymeric materials as a main component, containing 1.0-tolylbiguanide. Cleaning of a mold is performed by mounting the sheet-like mold cleaning composition on the mold. In the cleaning mechanism of the mold, at heating and vulcanizing, the 1,0- tolylbiguanide in a rubber material melts firstly and bleeds on the mold face so as to swell a contaminant. Thus, the contaminant on the mold surface can be peeled and removed easily. The contaminant peeled from the mold surface is adhered to a vulcanized sheet, integrated, and the sheet is taken out from the mold, so that the contaminant on the mold surface is removed and the mold is cleaned.

2. Description of the Related Art At the time of molding a thermosetting resin molding material using a molding die, a mold release agent contained in the thermosetting resin molding material exudes to the surface of the mold and exhibits a mold releasing action. To do.
If such a molding process is repeated, the mold releasability of the molded product is deteriorated and the appearance is deteriorated. The reason for this is that the release agent contained in the above-mentioned molding material exudes to the surface of the mold and gradually deteriorates while being successively laminated on the surface of the mold by repeating the molding process, and the effect as the release agent is lost. It is thought that this is because a pollutant layer is formed. In order to solve such a problem, the work of cleaning the mold is performed when a contaminant layer, which is a deteriorated layer of the release agent, is formed. For example, conventionally, a thermosetting melamine resin molding material was placed in the mold and molded and cured, and contaminants on the mold surface were integrated with the molded product, and a molded product in which the contaminants were integrated was prepared. It is practiced to clean the surface of the mold by removing it from the mold. However, in such a cleaning method, formalin is produced as a by-product as a condensate of the thermosetting melamine resin molding material to generate an odor, and it is difficult to remove this molded product and it takes a long time, so that the working environment is remarkably high. This deteriorates the cleaning workability.

Therefore, recently, when an unvulcanized rubber compound is used in place of the thermosetting melamine resin molding material, the compound is vulcanized in a mold to form a vulcanized rubber, which is then converted into a vulcanized rubber. In addition, the contaminants on the mold surface are integrated with the vulcanized rubber,
Then, a method of cleaning the surface of the mold by removing the vulcanized rubber from the mold has been proposed and partially implemented.

Among them, the mold contaminants when molding is repeated using a molding material containing polyethylene wax as a mold release agent are badly baked on the mold surface, and the unvulcanized rubber-based compound is used. There is a problem that it cannot be completely removed by the conventional cleaning method.

It is preferable to set in the range of 90/10. That is, BR is less than 50 (EPR
When the mold is washed with a cleaning sheet composed of the obtained composition for remanufacturing a mold, the releasability from the mold deteriorates. On the other hand, if the BR exceeds 90 (EPR is less than 10), the strength of the molded product is reduced when removing the rubber molded product during the molding work, and therefore inconvenience such as tearing occurs and the removal work from the mold is difficult. This is because it tends to be difficult. The EPR also includes ethylene-propylene-diene rubber (EPDM).

Next, since the mold cleaned with the mold cleaning composition of the present invention is free from contaminants and returns to the initial mold surface, it is usually a thermosetting resin molding material. When molding, a mold release agent must be applied to the surface of the mold in advance. For example, when molding a molding material containing polyethylene wax as a mold release agent, the same polyethylene wax may be applied. preferable. And
As a method of applying the polyethylene wax to the surface of the mold, it is preferable to use an unvulcanized rubber composition containing polyethylene wax prepared and formed into a sheet. Then, the polyethylene wax contained is applied to the surface of the mold by loading the sheet made of the unvulcanized rubber composition containing the polyethylene wax into the mold and heating the same as in the cleaning step. It is considered that this is because the polyethylene wax in the unvulcanized rubber composition melts during heat vulcanization and exudes to the mold surface to form a uniform release agent film on the surface. The content of the polyethylene wax is preferably set to 15 to 35 parts, and particularly preferably 20 to 30 parts, relative to 100 parts of the rubber material in the unvulcanized rubber composition. That is, when the content of polyethylene wax is less than 15 parts, a sufficient releasing effect is not exhibited, and when it exceeds 35 parts, it is excessively applied to the surface of the mold, and the molded product is cleaned and regenerated using the mold. This is because the appearance of the molded product tends to deteriorate when the resin is formed.
