Problems solved by technology

The addition of UFPNBR particles to EPDM significantly affects the vulcanization performance of EPDM, and the vulcanization effect of UFPNBR / EPDM blends is better with peroxide vulcanization systems; the observations of transmission electron microscopy and scanning electron microscopy show that UFPNBR particles It is always a dispersed phase, but it is not dispersed into the expected nanometer size in the EPDM matrix; the results of dynamic mechanical thermal analysis show that the blend has two glass transition temperatures, a two-phase structure and weak interfacial bonding

Abstract

The invention discloses ultrafine fully-vulcanized powdered styrene butadiene rubber tread rubber and a manufacturing method thereof. The tread rubber consists of the following materials in part by mass: 100 parts of tread rubber, 0 to 10 parts of ultrafine fully-vulcanized powdered styrene butadiene rubber (UFPSBR), 50 parts of carbon black, 1 part of accelerator CZ, 2.5 parts of anti-aging agent 4010NA, 3 parts of stearic acid, 5 parts of zinc oxide, 1.8 to 2.5 parts of sulfur, 6 parts of aromatic oil and 1 part of liquid wax. The manufacturing method comprises: adding the ultrafine fully-vulcanized powdered styrene butadiene rubber (UFPSBR) into three common tread rubber systems; and pretreating the UFPSBR by using silane coupling agent KH550 and saturated saline solution respectively. As the UFPSBR is used in the formula of the formula of tread rubber, high-performance tires can be produced and the application range of the UFPSBR is enlarged.

Description

Technical field [0001] The present invention involves a gum and its production method, especially the tire glue and production method of an ultra -fine full -all -all -chipphebode phenyl -borne phenyl -borne phenyl -borne phenyl -borne phenyl -borne phenolic phenolic phenolone. Background technique [0002] In modern life, the use of tires is quite wide. Generally speaking, it must have the following performance: (1) to bear a certain amount of load; (2) the rolling of high tolerance speed;The impact and vibration; (4) have good adhesion and traction; (5) have driving safety.These essential properties are the basic requirements for tires, and they should also have corresponding characteristics as different types of vehicles.Tires are rolled on the pavement under the load conditions. Due to the load effect and the reaction force of the pavement, complex dynamic deformation and wear during driving.The better the wear resistance of the tire, the better the road condition, the longer...
