Embodiment 1

[0034] Embodiment 1 of the present invention provides a composite rubber pad reinforced by helical nanofibers, and specifically provides an application in rubber of a reinforcing material composed of nano-palm fibers, helical nano-carbon fibers and nano-active calcium carbonate. The reinforcing material provided by the invention can not only effectively improve the mechanical properties of the rubber, but also have the effect of shortening the vulcanization rate.

[0035] In the present invention, nano palm fiber, helical nano carbon fiber and nano active calcium carbonate are added to the rubber compounding system in coordination. Nano activated calcium carbonate improves the dispersibility of nano palm fibers and helical carbon nano fibers in the rubber system, so that the nano palm fibers and helical carbon nano fibers can be uniformly dispersed in the rubber matrix. At the same time, the synergy of the three materials is to improve the comprehensive properties of the rubbe...

Abstract

The invention discloses a spiral nanofiber reinforced composite rubber pad. The composite rubber pad is composed of a first rubber layer and a second rubber layer, the first rubber layer and / or the second rubber layer are / is made of a composite reinforcing material, and the composite reinforcing material is composed of nanometer palm fibers, spiral nanometer carbon fibers and nanometer active calcium carbonate. The invention provides an application of a reinforcing material composed of nanometer palm fibers, spiral nanometer carbon fibers and nanometer active calcium carbonate in rubber. The reinforcing material provided by the invention not only can effectively improve the mechanical properties of rubber, but also has the effect of shortening the vulcanization rate.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and particularly relates to a composite rubber pad reinforced by helical nanofibers. Background technique [0002] As a new type of carbon material, helical carbon nanofibers (HCNFs) have excellent properties such as low density, high strength, high temperature resistance, corrosion resistance, friction resistance, and good electrical conductivity. Typical chiral characteristics and good elasticity. Therefore, helical carbon nanofibers are widely used in rubber reinforcement. [0003] The dispersion of fillers in reinforced rubber has always been the two major technical difficulties restricting rubber reinforcement. Compared with the traditional spherical carbon black aggregates with primary particles, the new one-dimensional carbon nanofillers are more difficult to disperse uniformly in the rubber matrix, and their dispersibility research is more challenging. Because the helical carb...
