Description
Technical field
The present invention relates to a kind of glue and preparation method thereof, particularly relate to tread rubber of a kind of ultra-fine form of finely divided powder, mehtod styrene-butadiene rubber(SBR) and preparation method thereof.
Background technology
In the life, the purposes of tire is quite extensive in modern times, and it must possess following performance in general: certain load can be born in (1); (2) the higher rolling of ability tolerance speed; (3) impact in the time of relaxing wheel rolling and vibrations; (4) sticking power and tractive force are preferably arranged; (5) possesses driving safety.These indispensable performances are the basic demands to tire, along with the use on the different sorts vehicle also should possess corresponding characteristic.Tire rolls on the road surface under loading condition, owing to receive the reactive force on load and road surface, has experienced complicated dynamic deformation and wearing and tearing in the process of moving.The tyre surface wear resistance is good more, and the track situation is good more, and the abrasion life-span of tire is long more.Therefore study the performance that how to improve tread rubber and have great importance, the research work of this respect is also a lot.In the dynamic vulcanization processing of common fully sulfurized thermoplastic elastomer; The elastomerics particle diameter of disperse phase is difficult to be controlled at small range; The mean diameter of rubber particles is generally greater than 200nm, and the particle diameter of rubber particles constantly changes along with the variation of factors such as course of processing mid(dle)shear rate.
(Ultra-fine full vulcanized powdered rubber is to use brand-new theory and innovate the fully vulcanized powder rubber product that the technological process of production is produced through radiation crosslinking UFPR) to ultra-fine fully vulcanized powder rubber.The scientific payoffs that this is great has received the high evaluation of national departments concerned and the very big concern of relevant industries.
Ultra-fine fully vulcanized powder rubber has overcome the shortcoming that ordinary powder rubber is occurred in the dynamic vulcanization process in the processing of rubber/mould blend type thermoplastic elastomer, the Beijing Chemical Research Institute has done a lot of work in this respect.Tang Yuanwang etc. (Tang Yuanwang etc. the structure of ultra-fine form of finely divided powder, mehtod NBR/EPDM blend and performance [J]. rubber industry; 2006,53 (4): 223-2300) vulcanization characteristics of the ultra-fine form of finely divided powder, mehtod NBR of experimental study (UFPNBR)/EPDM blend, phase structure, dynamic properties, processing characteristics and physicals.The UFPNBR particle adds the curability that has obviously influenced EPDM among the EPDM, and the UFPNBR/EPDM blend adopts the peroxide vulcanizing system cure efficiency better; Transmission electron microscope and sem observation show that the UFPNBR particle is always disperse phase in UFPNBR/ EPDM blend, but in the EPDM matrix, is not dispersed into the nano-scale of expection; The dynamic mechanics heat analysis result shows that there are two second-order transition temperatures in blend, is a little less than the combination of two phase structure and interface.
If powdered rubber can obtain good dispersion in rubber matrix; Make it should have certain positive influence to aspect of performances such as meridian tyre abradability, anti-slippery, rolling resistance, this all is very favourable to save energy, protection environment.
Summary of the invention
