Abstract

The invention belongs to the technical field of rubber materials, particularly a rubber material for weather-resistant and aging-resistant plate type rubber support. The rubber material comprises the following components: rubber type chlorinated polyethylene (CM), natural rubber, zinc oxide, stearic acid, magnesium oxide, an antiaging agent, paraffin, carbon black, modified nano attapulgite, a plasticizer, an organic peroxide vulcanizing agent, sulfur and an accelerant. The rubber material for weather-resistant and aging-resistant plate type rubber support can be prepared by virtue of the steps: plastifying, mixing, vulcanizing and the like, wherein the rubber material has the characteristics of being high in mechanical strength, strong in weather resistance, heat aging resistant, ozone aging resistant and the like.

Description

technical field [0001] The invention belongs to the technical field of rubber materials for rubber bearings, and in particular relates to a rubber material for weather-resistant and aging-resistant plate rubber bearings. Background technique [0002] The plate rubber bearing is an important structural part of the bridge superstructure. It plays an important role in the bridge, such as bearing load, transmitting displacement, and proper rotation angle. In addition to meeting the basic physical and mechanical performance indicators specified in the standard, it should also have excellent aging resistance. At present, the plate rubber bearing in the project will appear cracks in a short period of time. The main problem is that the rubber material constituting the support has poor weather resistance and ozone aging resistance, which makes the plate rubber bearing crack in advance, shortening The service life of the plate rubber bearing is extended. content of the invention ...
