Abstract

The invention belongs to the technical field of new materials for manufacturing rubber tires, and particularly relates to application of modified rice bran oil in preparation of tire rubber, a rubber composition and a tire. The rubber composition plasticized by using modified rice bran oil comprises 100 parts by weight of a pure rubber component, 1-40 parts by weight of modified rice bran oil and 30-120 parts by weight of a reinforcing material, wherein the modified rice bran oil is prepared from rice bran oil through olefin addition reaction. According to the composition, a petroleum-based plasticizer is replaced through the good plasticizing effect of the modified rice bran oil, the number of double bonds of the rice bran oil is reduced through modification from the perspective of modification, the influence on rheology and physical and mechanical properties is reduced, and a good foundation is laid for developing environment-friendly tires.

Description

technical field [0001] The invention belongs to the technical field of new materials for manufacturing rubber tires, and in particular relates to the application of modified rice bran oil in preparing tire rubber materials, rubber compositions and tires. Background technique [0002] In the field of tire manufacturing, plasticizer is one of the indispensable materials. Generally, plasticizers used in tire rubber materials are a class of compounds with low molecular weight, mainly paraffinic base oils, naphthenic base oils and aromatic base oils. Among them, the traditional aromatic oil (DAE) has good compatibility with rubber, can endow tires with good performance, and is most widely used in tire production. [0003] With the introduction of the REACH Act by the European Union, tire companies have begun to pay attention to the research and application of environmentally friendly rubber oil in order to ensure the environmental protection performance of tires. At present, it...
