Abstract
The present invention discloses a carbon-nanotube-reinforced tire comprising a rubber part and a framework material, the framework material and the rubber part are connected by a binder, carbon nanotubes are added into the rubber part material and the binder, a large number of 1-100nm nano carbon particles are grown on the surface of the carbon nanotubes, and more than 70% of the surface area of the carbon nanotubes are grown with the 1-100nm nano carbon particles. The carbon nanotubes are interpenetrated in the rubber part and between the interfaces to form an integrated thermal-conducting and stress dispersion network in the tire, heat and stress generated in the use process can be effectively dispersed, the use strength and heat dispersion capacity of the tire can be improved, and the tire use life can be extended. At the same time, part of the carbon nanotubes form rigid contact points between the interfaces to prevent relative slip between the interfaces and improve interfacial adhesion strength. Carbon nanotubes perpendicular to the tread portion can improve the road holding property of the tire, thereby enhancing the safety of the tire.
Description
Technical field
The present invention relates to chemical technology field, be specifically related to the tire that CNT strengthens.
Background technology
Tire, primarily of tyre surface, tire shoulder, sidewall, carcass and framework material composition, is connected by binder phase between rubber components with skeleton.The performance possessed needed for each position of tire is different, thus different to the requirement of formula, as the position that tyre surface is with earth surface in tire running process, tread properties directly affects the safety in service life of tire and driving process, requires that tire protector will have well ageing-resistant, resistance to abrasion, thorn resistance, elasticity and grasp performance, wet-sliding resistant performance to ground; Tire shoulder is the position connecting tyre surface and sidewall, major requirement its there is antifatigue and perfect heat-dissipating.Because each position performance requriements is different, selected glue kind and formula thereof also difference to some extent.Therefore, require higher to the interfacial adhesion strength between each position of tire.How not affect while promoting tire each position performance and improve even the key issue that interfacial adhesion strength is raising overall performance of tire.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of CNT and strengthens tire, by adding the CNT of special appearance at all rubber parts of tire and adhesive agent part, provides a kind of enhancing tire with higher interfacial adhesion strength.
A kind of CNT provided by the invention strengthens the technical scheme of tire, the tire that a kind of CNT strengthens, it comprises rubber components and framework material, is connected between rubber components with framework material by binder phase, and material and the adhesive agent of described rubber components are added with CNT
In an optimal technical scheme of the present invention, what described carbon nano tube surface was amassed more than 70% all covers/grows the carbon granule having 1-100nm, and be preferably that carbon nano tube surface amasss more than 40% all covers/grow the carbon granule having 1-100nm; More preferably should, what carbon nano tube surface was amassed more than 5% all covers/grows the carbon granule having 1-100nm.
In an optimal technical scheme of the present invention, described carbon granule is spherical, sheet, dendroid.
In an optimal technical scheme of the present invention, CNT external diameter is 5-100nm, and length is 1-20 micron.
In an optimal technical scheme of the present invention, the addition in rubber components of CNT is 1-30:100 weight portion, and the addition in rubber components of preferred CNT is 1-10:100 weight portion.
In an optimal technical scheme of the present invention, the addition in a binder of CNT is 0.1-10:100 weight portion, preferably, the addition in a binder of CNT is 0.1-5:100 weight portion, more preferably, the addition in a binder of CNT is 0.1-2:100 weight portion.
Described tire comprises rubber components and framework material, and rubber components comprises tyre surface, tire shoulder, sidewall, carcass, is connected between rubber components with skeleton by binder phase.And described rubber comprises natural rubber and neoprene.
CNT of the present invention is prepared by CVD, can be prepared by the method such as preparing material with carbon element disclosed in patent application CN103864050A, certainly can also by well known to a person skilled in the art that other method maybe can expected prepares.
Above-mentioned CNT is obviously different from the pattern of conventional carbon nanotube: the surface of this CNT is long a large amount of nano carbon particle, significantly increases the external surface area of single-root carbon nano-tube, significantly enhances the sympathy of CNT and rubber.
This CNT mutually interts between rubber part and interface, heat conduction and the stress dispersion net of integral type is formed in tire, effectively can disperse the heat that produces in use procedure and stress, improve working strength and the heat-sinking capability of tire, extend the service life of tire.Meanwhile, part CNT forms rigid contact between interface, can stop the Relative sliding between interface, improves interfacial adhesion strength.CNT that is vertical and tread portion can improve the adherence properties of tire, thus improves the safety in utilization of tire.
Tire perfect heat-dissipating of the present invention, working strength is large, bind strength is high, safety in utilization is excellent, long service life.
