Large Scale Preparation And The Application In Fuel-Efficient Tyres Of CNTB/Rubber Composite

The carbon nanotubes have long been regarded as the most tenacious, the strongest man-made materials. As a supplement, due to their excellent electric conductivity, on conductive and communication areas, they also have caused widespread interests. However, due to their tiny size, their outstanding performance can only be showed when they are uniformly distributed in the filling matrix. These two points limit the roles that CNTs play in reinforcing and functionalization so as to restrict the large-scale application of carbon nanotubes in production. In this article, in order to make CNTs have a better dispersion in the rubber, we apply a relatively good dispersion carbon nanotubes (CNTB) and a new type of silane coupling agent to further strengthen and modify the interface of the CNTB and the rubber matrix. On the other hand, we apply the new composite into the formula of the fuel-efficient tire tread, and prepare the antistatic fuel-efficient tyres.Our work is mainly carried out in the following several aspects:1.By using a relatively good dispersion carbon nanotubes (CNTB), we have established the carbon nanotubes net in the composite materials, so as to realize the antistatic effect of the the fuel-efficient tire tread composite.2.Through applying a new type of rare earth butadiene as a raw material, which is added to the fuel-efficient tire tread composite, we have successed in reducing the hysteresis loss factor Tanδ (7%strain&60℃), so as to reduce the effect of tyre oil consumption.3.Through the use of a new type of silane instead of the original Si69, we have made SiO2, which is a common fuel-efficient tires additive, have a better dispersion in composites, a better combination of the SiO2and the rubber matrix, so as to educing the hysteresis loss factor Tan8(7%strain&60℃) and the effect of tyre oil consumption.In addition we also found that in the SiO2better-dispersion system, CNTB also have a better dispersion, and it is easier for the CNTB to form a conductive network.4.In order to further study the influence that different packing system, different packing filling amount, and different filler dispersion situation on the dispersion situation of carbon nanotubes in composite, we further design several different formula of mixed filling system, and study the CNTB conductive network formed in every situation.
