The invention relates to the technical field of rubber, in particular to a production technology of an elastic rubber pad. The production technology includes the following steps of preparation, wherein raw materials are prepared and include natural rubber, butadiene-styrene rubber, nitrile-butadiene rubber, a toughener, an elasticizer, calcium zincate, quartz powder, bentonite, zinc oxide, stearic acid, a plasticizer and an antiager, and the elasticizer includes butyl conjugated diene, pentaerythritol oleate and maleic anhydride at the addition proportion of 1:2:1; mixing, wherein the substances, except the elasticizer, in the raw materials are fully mixed and then put into a mixer for mixing treatment; mould forming, wherein the raw materials obtained after mixing are subjected to forming treatment with a mould and then cooled; vertical stress removing treatment, wherein formed rubber is soaked in clear water and then cooked for 5-10 min at 80-100 DEG C. The rubber produced with the production technology is low in price, high in elasticity and toughness, long in service life and not prone to permanent deformation.
