Abstract

The invention discloses a preparation method of magnetic-sensitive rubber, and belongs to the technical field of polymer materials. The preparation method of the magnetic-sensitive rubber comprises the following steps: successively weighing 50 to 60 parts of natural rubber, 30 to 40 parts of styrene-butadiene rubber, 5 to 6 parts of zinc oxide, 2 to 4 parts of an accelerator, 2 to 3 parts of stearic acid, 3 to 4 parts of a mixed antioxidant, 2 to 4 parts of a tackifier, 3 to 6 parts of sulfur and 10 to 18 parts of an additive calculated in parts by weight, mixing the natural rubber and the styrene-butadiene rubber in a mixer, adding zinc oxide, stearic acid, the mixed antioxidant, the accelerator, the tackifier and the additive into the mixer, mixing to obtain a blank, mixing the blank with the sulfur, and performing vulcanization at the temperature of 160 to 190 DEG C to obtain the magnetic-sensitive rubber. The magnetic-sensitive rubber prepared by the technical scheme of the invention has the characteristic of excellent tensile strength and further has broad prospects in development of the polymer material industry.

Description

technical field [0001] The invention discloses a preparation method of magnetic sensitive rubber, which belongs to the technical field of polymer materials. Background technique [0002] Magneto-sensitive rubber is a kind of magnetorheological material, also known as magnetorheological elastomer. It is a new type of functional material and intelligent material whose rheological properties can be controlled by an external magnetic field. Due to its fast response speed, good reversibility (it returns to the initial state after the magnetic field is removed), and the continuous change of the mechanical, electrical, and magnetic properties of the material can be controlled by adjusting the magnetic field, it is used in aerospace, automotive, vibration control and other fields. It has broad application prospects. The research on magnetorheological elastomers is relatively late, and the research scope mainly focuses on magnetorheological fluids and their applications. Magnet...
