Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment:

[0014] The raw material components, content and tire production process of the present invention can be prepared according to the existing conventional technology, and the specific steps are as follows:

[0015] One-stage masterbatch mixing: Add natural rubber to internal mixer GK400, add carbon black, anti-aging agent and other raw materials except sulfur and accelerator, press the bolt for 30 seconds, add environmental protection oil, press the bolt for 30 seconds, lift the bolt again, Press the plug to 165°C to discharge the glue.

[0016] Two-stage masterbatch mixing: Add one stage of masterbatch, press the bolt for 30s, lift the bolt and press the bolt again for 30s, lift the bolt and press the bolt to 165°C to discharge the glue.

[0017] Final rubber mixing: Add the second-stage rubber compound, sulfur and accelerator, press the plug for 30s, lift the plug and press the plug ...

Abstract

The invention relates to the technical field of rubber, in particular to a tread rubber composition for a standard testing tire. The composition is characterized by comprising 35-70 parts by weight of butadiene rubber, 30-65 parts by weight of natural rubber, 30-60 parts by weight of carbon black, 5-20 parts by weight of extending oil, 1.5-2.5 parts by weight of sulfur and other rubber additives commonly used in the tire industry. The reliability of mechanical properties such as tensile strength and stress at definite elongation of a rubber material is guaranteed; at the same time, and the prepared tire has an effect of scientific and effective catching performance evaluation in a wetland and a snowfield, and can also be used for other evaluation of abrasion performance, rolling resistance performance, pavement frictional characteristics, noise and the like.

Description

technical field [0001] The invention relates to the technical field of tire rubber, in particular to a rubber composition for the tread part of a 225 / 75R16C TR675 standard test tire. Background technique [0002] As is well known, ISO and the International Vocabulary of Metrology give the definition of "standard material (reference material)": that is, "having one or more sufficiently homogeneous and well-defined properties for use in calibrating measuring devices, evaluating measuring methods, or giving A material or substance assigned a material value", the standard test tire is a standard substance in the tire industry, which mainly serves the implementation and application of tire performance testing and grading standards, and is a necessary condition to ensure the consistency and comparability of measurement results. [0003] Internationally, the outdoor test of tires, such as wet and snow grip performance tests, uses standard test tires for comparison, that is, a group...
