Abstract

The invention belongs to the field of functional materials and in particular relates to a combined regenerated substance and magnetic compound material and a preparation method thereof. The material comprises the following components by weight percent: 2%-5% of chromium sesquioxide, 11%-15% of bentonite, 20%-25% of a waste glass iron-praseodymium magnetic oxide complex body and the balance of phenolic resin. The material provided by the invention is pollution-free and relatively higher in damping performance and has a vibration attenuation effect. The preparation method provided by the invention is simple in process, low in production cost and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to a regenerative magnetic compound composite material and a preparation method thereof. Background technique [0002] CN200410046625.8 applies for an asphalt-based composite damping material and its preparation method and application, which belongs to the preparation and utilization of a polymer damping material. It uses polymer modified asphalt as the base material, and then adds fillers, damping After adding various inorganic fillers such as natural agent, damping agent, and other auxiliary agents, it can be made into a kind of asphalt-based composite damping material that can meet the purpose of the present invention by adding water and mixing. Systematic research and experimental investigations have been carried out on the dosage and dosage, and a formula with relatively good performance has been obtained. It can be widely used in various working conditions that...
