Abstract

The invention provides a method for preparing an energy-saving composite damping material. The method comprises the following steps: 1, adding carbon fibers into an acetone solution for stirring at a high speed, adding a curing agent, stirring until the curing agent is completely dissolved, adding monomers butyl methacrylate and xylene, and carrying out a reaction so as to obtain a mixture I; 2, mixing chlorinated butyl rubber and butadiene-acrylonitrile rubber so as to obtain a mixture II; 3, sequentially adding zinc oxide, an accelerant and an antioxidant into the mixture II, and compounding so as to obtain a mixture III; 4, adding the mixture III into carbon black and sulfur subjected to drying treatment, and mixing so as to obtain a mixture IV; 5, uniformly mixing the mixture I and the mixture IV, pouring into a mold coated with a release agent, removing the solvent in vacuum, taking out the mold for performing gradient cooling to a normal temperature, so as to obtain the product. According to the added carbon fibers, the quality of the prepared damping material can be improved, and energy conservation and emission reduction in the preparation process are realized.

Description

technical field [0001] The invention belongs to the technical field of preparation of composite materials, and in particular relates to a preparation method of an energy-saving composite damping material. Background technique [0002] With the development of modern industry, problems such as vibration, noise and fatigue will inevitably occur during the use of machinery and instruments. These problems will reduce the performance of the equipment, destroy the stability and reliability of the equipment operation, and may cause safety accidents in severe cases, resulting in loss of personnel and property, and also pollute the environment and endanger the physical and mental health of the human body. Therefore, shock and noise reduction can effectively reduce the occurrence of accidents and prolong the service life of equipment. The elimination of negative effects such as vibration noise is mainly solved by reducing the generation of vibration noise and using damping materials. ...
