In recent years, due to the raising of people's environmental protection and awareness of saving energy, and country has put into effect a variety of related restricting vehicle fuel consumption methods
Rule, therefore people require increasingly to improve to tire, low power consuming tire-low rolling resistance tyre is gradually come into the sight of people,
Low energy consumption for this tire, reduces the pollution to environment, and the concept of " green tire " is thus born.The 1990s people
This saying of green tire is had recognized that.After tire working person at that time carries out silane surface processing to white carbon, substitution passes
System reinforced filling carbon black, the rolling resistance of tire become smaller.Since the concept comes out, strategic meaning has been played to the development of tyre industry
Justice is the target that various countries fall over each other exploitation.
Tire tread is that automobile is uniquely in direct contact component with ground, and it is most harsh to bear extraneous stress, by from outside
The impact of various adverse circumstances includes the friction between ground, the puncture of extraneous sharp substance, vibrations of the rough road to it
And impact etc., this requires tires, and there is excellent wear-resisting, cut resistant, tear-resistant, anti-slippery and low rolling to hinder, low life
Heat and ageing-resistant performance etc..But it is often conflicting between the various performances of tire, it is difficult to while performance is improved, improve one
Kind or while two kinds of performances, the third performance often reduces, the wearability of tire, rolling resistance and anti-slippery (adherence properties)
Three big performances are referred to as " devil's triangle ", thus develop " green tire " reduce tire rolling resistance, ensure it is wear-resisting, grab etc.
Not reducing for performance be the emphasis that we to be studied is also difficult point.Improving three kinds of performance studies of tire tread is looked forward to China's tire
The technical support and guarantee that industry is run business big and strong simultaneously for energy-saving and emission-reduction, reduce discharge, environmental protection etc. all with strategy
The meaning of property.
