Abstract

The invention discloses a formula of an environmental-friendly rubber for preparing a tire and a preparation method thereof. The formula comprises the following raw materials: emulsion-polymerized styrene butadiene rubber, solution polymerized styrene butadiene rubber, high-structure carbon black, a dispersing agent, anti-aging agents, active agents, a vulcanizing agent, accelerants and an environmental-friendly processing oil, wherein the ratio of the parts of the solution polymerized styrene butadiene rubber to the parts of the emulsion-polymerized styrene butadiene rubber is at least 2:1, the ratio of the total parts of the emulsion-polymerized styrene butadiene rubber and the solution polymerized styrene butadiene rubber to the parts of the high-structure carbon black is at least 2:1, the ratio of the parts of the high-structure carbon black to the parts of the environmental-friendly processing oil is at least about 2:1, and the ratio of the parts of the active agents to the parts of the high-structure carbon black is at least about 1:20. By adopting the technical scheme of the invention and compared with the prior art, the formula and the preparation method provide the tire adopting an alternative softener to replace high aromatic oil.

Description

technical field [0001] The invention relates to a formula and a preparation method of an environment-friendly rubber used for making tires. Background technique [0002] In the prior art, polycyclic aromatic hydrocarbon rubber processing oil is widely used in the rubber processing process. This processing oil contains PAHS, heavy metals and carcinogens, which not only endanger the human body, but also cause harm to the soil and organisms, and seriously pollute the environment. For this reason, the European Union revised Directive 76 / 769 / EEC according to Directive 2005 / 69 / EC, "RoHS" environmental directives, such products must meet the safety of USP (Pharmacopia) and FDA and PHEUR (European Pharmacopoeia), and limit high PAHS processing oil Tires containing such processed oils are manufactured, sold and imported / exported in the EU, so the development and application of aromatic oil substitutes is imperative. Contents of the invention [0003] The technical problem to be so...
