Abstract

The invention belongs to the field of functional materials, and in particular relates to a magnetic damping composite material and a preparation method thereof. The material comprises the following components in percentage by weight: 8 to 10 percent of kaolin, 8 to 11 percent of magnesium oxide, 24 to 28 percent of waste cement cerium-manganese composite oxide composite body, and the balance of phenolic resin. The invention aims to provide a magnetic damping composite material, which has the characteristic of high maximum damping factor. The invention also aims to provide the preparation method of the magnetic damping composite material, which has a simple process, and is low in production cost and applicable to industrial production.

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to a magnetic damping composite material and a preparation method thereof. Background technique [0002] CN201110029579.0 application discloses a preparation method of high damping epoxy resin composite material, including damping paint, fiber fabric, epoxy resin and curing agent; the steps are as follows: 1) Coating fiber fabric with damping paint to form a damping laminate ; 2) Insert the damping layer into several layers of fiber fabrics to form a laminated damping reinforcing material layer; 3) Take epoxy resin and curing agent and mix them evenly in a mass ratio of 100:28-32 to form an epoxy resin system ; 4) Spread the damping reinforcement material layer in step 2) in the mold, and use the VARI process to pour the epoxy resin system in step 3) into the damping reinforcement material layer to make it composite, and then pass through the temperature of 80°C-100°C...
