7, a method of manufacturing a roller 100 for a conveyor with a ceramic wear prevention member according to the present invention will be described. First, the surface of the metal roller 110 is subjected to shot peening Step ST-100 is performed.

Thereafter, after the shot peening is performed, the surface of the metal roller 100 is subjected to a cleaning step (ST-120) of washing the metal roller with toluene.

As described above, an unvulcanized rubber plate 120 is attached to the surface of the metal roller 100 that has been cleaned with toluene. To this end, an oil-based adhesive is applied to the surface of the metal roller 110 washed with toluene, Followed by drying. At this time, 'P-112F' manufactured by THIXON may be used as the oil-based adhesive used for attaching the unvulcanized rubber plate 120. Of course, various kinds of adhesives may be used under the conditions of the same adhesive force as that of the above 'P-112F'.

Next, an oil-based adhesive for attaching the rubber-like rubber sheet 130 is applied to the surface of the unvulcanized rubber sheet 120 attached to the surface of the metal roller 110 and dried for a predetermined period of time. At this time, a rubber-like adhesive may be used. The rubber-like adhesive may be prepared by adding an oil-based adhesive (for example, CILBOND 24) to a solution in which the unvulcanized rubber is melted. The unvulcanized rubber and toluene are mixed, and an oil-based adhesive (for example, CILBOND 24) is added thereto to prepare a rubber-like adhesive. A rubber-like adhesive can be prepared by mixing 40 wt% of the unvulcanized rubber and 60 wt% of toluene, and mixing 50 wt% of the mixture and 50 wt% of an oil-based adhesive (e.g., CILBOND24). When the rubber-like unbranched rubber sheet 120 is attached, the unvulcanized rubber sheet attaching process ST-130 is completed.

Next, a ceramic member attaching process (ST-140) for attaching the ceramic wear preventing member 130 is performed. The surface of the ceramic wear-preventing member 130 facing the unvulcanized rubber plate 120 is sandblasted (for example, sand paper # 24) so as to attach the ceramic wear-resistant member 130 to the unvulcanized rubber plate 120 After that, the surface is coated with an adhesive and dried. At this time, either the CILBOND 24 or the rubbery adhesive may be selectively used as the adhesive used. Of course, various types of adhesives may be used under the conditions of the same adhesive force as the CILBOND 24 or the rubber-like adhesive.

Meanwhile, when the above process is completed, the process of attaching a filler member (ST-150) attaching the filler member 140 to the gap formed between the axial direction and the circumferential direction of the ceramic wear preventive member 130 is performed. An adhesive is applied to the lower surface of the filler member and is attached to the ceramic wear-preventing member 130 at a spaced distance.

At this time, when the rod-like filler member 140 is provided in the circumferential direction, the filler member 140 is attached in the axial direction. However, the mounting arrangement of the rod-like filling member 140 and the block-shaped filling member 140 on the basis of the circumferential direction and the axial direction may be provided as necessary as described above.

After the filler member 140 is attached between the ceramic wear-preventing members 130 through the above-described process, the ceramic wear-preventing member 130 is pressed and fixed by being wound with a cord such as a nylon rope T ST-160).

Next, the ceramic wear preventing member 130 with the nylon rope 140 and the metal roller 110 pressing the filler member 140 are put into an oven to perform a vulcanizing step (ST-170) for vulcanizing with water vapor.

In this process, while maintaining the temperature of the inside of the oven at 120 ° to 130 ° for 5 hours, steam is preferably supplied while maintaining the internal pressure at 4 kgf / cm 2 (absolute pressure). At this time, since the vulcanization temperature is usually 140 °, the temperature inside the oven is maintained at 120 ° to 130 °, so that the hardness of the unvulcanized rubber sheet 120 increases (about 60 to 70 shore).
