Abstract

The invention provides a special material for a nanometer rubber support. The special material is prepared from, by weight, 100 parts of natural rubber, 2-6 parts of an active agent, 0.1-1.0 part of an accelerant, 3-10 parts of an age resister, 1.5-3 parts of sulphur, 15-25 parts of carbon black and 3-8 parts of modified nanometer silicon dioxide. According to the special material, a nano-scale compounding agent which is smaller in particle size, large in specific surface area and high in surface activity is uniformly dispersed into a rubber matrix, and the nano-scale compounding agent and rubber molecular chains form a three-dimensional cross-linked network structure which is high in density; the nanometer rubber support prepared from the special material is longer in service life, better in anti-knock restoration capability and better in shock absorption and shock insulation effect.

Description

technical field [0001] The invention belongs to the technical field of special materials for rubber bearings, and in particular relates to a special material for nanometer rubber bearings. Background technique [0002] The existing shock-isolation rubber bearings are mainly made of alternately stacked multi-layer rubber pads and steel plates, which are processed through the overall thermal vulcanization of the mold. They have good vertical bearing capacity and horizontal deformation capacity, and can effectively extend the life of buildings during earthquakes. Self-seismic period, thereby improving the earthquake resistance and shock absorption capacity of the building. However, due to the disadvantages of poor thermal conductivity of rubber itself and easy aging in natural environments, rubber bearings for thick products are mainly vulcanized at low temperature and for a long time, resulting in low production efficiency and short service life. At the same time, because the...
