| titleOfInvention | A method of manufacturing a cushioning member provided in a bollard that is not discolored by ultraviolet light and has a long life and impact relaxation by stretching, stretching and elasticity |
| abstract | The present invention relates to a bollard in which a cushioning member installed to prevent entry of a vehicle is usually integrally provided, wherein the cushioning member is a rubber raw material mixture composed of natural rubber, synthetic rubber, latex and carbon black raw materials and the rubber. Zinc oxide (2-mercptobenzothia-zole), MBTS (2,2'-Dibenzothiazyl disulfide), DCP (Dicumyl peroxide), sulfur (Sp), sphere for promoting the raw material mixture For crosslinking (vulcanization) of accelerator raw material mixtures consisting of marron, stearic acid (S/T), paraffin wax (P/W), antioxidants and anti-discoloration raw materials for preventing discoloration and reinforcement fillers that improve the physical properties of rubber To prepare a rubber sheet in a state of mixing and mixing under temperature conditions, to cut a rubber sheet manufactured as described above to a certain size to produce a rubber piece, and input a plurality of cut rubber pieces to the lower mold of the molding frame, Place the bollard frame on the upper side of the rubber piece put into the lower mold, put the cut rubber piece on the upper part of the bollard frame, lower the upper mold of the molding frame, and lower the upper mold so that it is not fully engaged with the lower mold, 140 degrees ~ The first temporary molding is performed once or more and three times or less to melt the hard rubber pieces in a soft state at a temperature of 150 degrees for 2 to 3 minutes, and after the first temporary molding, the upper and lower molds are fully tightened and 140 degrees to 150 degrees. The rubber pieces were melted by heating for 25 minutes at a temperature of 40 degrees and a pressure of 40 to 50 (kgf/cm2) to form an integral part of the bollard frame. |
