Carbon nano environment-friendly rubber composite and preparation method thereof

Abstract

The invention discloses a carbon nano environment-friendly rubber composite and a preparation method thereof. The carbon nano environment-friendly rubber composite consists of the following raw materials in parts by weight: 100 parts of rubber, 1-10 parts of carbon nano rubber masterbatch or carbon nanomaterial containing 1-10 parts of carbon nanomaterial, 20-90 parts of carbon black or regenerated carbon black, 0-50 parts of regenerated rubber powder, 1-3 parts of sulfur and 3-14 parts of compounding ingredient, wherein the compounding ingredient consists of an anti-aging agent, zinc oxide, stearic acid and an accelerant. In the invention, by combining carbon nanomaterial (carbon nanotube and graphene) having excellent high reinforcing, high heat conducting (cooling) and high electric conduction properties with the regenerated carbon black and the regenerated rubber (powder), the filler content is remarkably increased and original strength of rubber product still can be kept and even improved. The prepared environment-friendly rubber product has double advantages of high performance and low cost and promotes good circulation of waste tire treatment.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a carbon nano-environmental rubber composite material and a preparation method thereof. Background technique [0002] A large number of waste tires are produced in the world every year. Reclaimed rubber (powder) and recycled carbon black are the main products of waste tire treatment. However, due to the poor reinforcing performance of recycled carbon black and the poor strength of reclaimed rubber (powder), they It cannot be used in large quantities in tires and rubber products. [0003] The current technology only adds a single regenerated carbon black or reclaimed rubber (powder) to tires or rubber products to achieve the purpose of reducing costs, but based on the sharp drop in strength after addition, the amount added in actual production is small, and it is often Used in the preparation of lower-end rubber products. [0004] Chinese patent CN201310457717.4 disclose...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the technical problem that the existing reclaimed rubber (powder) and regenerated carbon black cannot be fully utilized, the present invention combines carbon nanomaterials (carbon nanotubes and graphene) or rubber masterbatches containing carbon nanomaterials with reclaimed rubber powder, regenerated Carbon black is mixed together and added to tires and rubber products according to a certain formula to make up for the strength defects caused by adding reclaimed rubber powder and carbon black in tires and rubber products. At the same time, it can reduce costs and improve performance.
