Problems solved by technology

[0002] In production, under a certain temperature and molding pressure, in order to make the rubber material change from plastic to elastic, and to maximize the cross-linking density and optimize the physical and mechanical properties, the time used for the optimization of physical and mechanical properties is called the vulcanization time of rubber products. The vulcanization time of rubber mainly depends on However, due to the uneven rubber thickness of individual products, the vulcanization time is inconsistent, which affects the actual use function of the finished shoe. For example, the vulcanization time is correspondingly shorter if the forefoot of the sole is thinner, and the vulcanization time is correspondingly shorter if the heel is thicker. However, in actual production, if the vulcanization time is determined according to the vulcanization time of the thinner forefoot, the rubber at the thicker part of the heel rubber will be under-vulcanized, resulting in a lack of functionality. However, if the vulcanization time is determined with a thicker heel rubber Time will cause the forefoot to take too long, resulting in rubber overvulcanization and aging, which will also cause waste products

Abstract

The invention relates to a rubber moulded shoe. The rubber moulded shoe comprises a half sole and a heelpiece, wherein the half sole comprises the following components in parts by weight: 80-120 parts of neoprene, 2-6 parts of magnesium oxide, 0.3-0.7 part of stearic acid, 3-7 parts of semi-reinforcing carbon black, 3-7 parts of zinc oxide, 0.15-0.55 part of accelerator TMTD-II and 0.2-1 part of anti-aging agent NBC; the heelpiece comprises the following components in parts by weight: 80-120 parts of neoprene, 2-6 parts of magnesium oxide, 0.3-0.7 part of stearic acid, 3-7 parts of semi-reinforcing carbon black, 3-7 parts of zinc oxide, 0.3-0.7 part of accelerator CBS and 0.2-1 part of anti-aging agent NBC. The rubber moulded shoe has the beneficial effects that the half sole and the heelpiece adopt different types of accelerators in different parts by weight to achieve consistency of the vulcanization time of the whole shoe, that is, the vulcanization speed of the rubber on the thicker part of the heelpiece is increased and the vulcanization speed of the rubber on the thinner part of the half sole is reduced, so that the vulcanization time of the rubber on the two parts is the same at the same vulcanization time and the same temperature.
