Abstract

The invention discloses a sound insulation material, and a preparation method and an application thereof. The sound insulation material comprises, by weight, 5-7 parts of soda powder, 10-15 parts of fly ash, 5-8 parts of nano-montmorillonite, 40-50 parts of epoxy resin, 4-6 parts of wood fibers, 8-10 parts of hollow glass beads, 10-15 parts of polysiloxane rubber, 2-3 parts of castor oil and 3-5 parts of magnesium oxide. The sound insulation material is obtained by mixing and cooling the raw materials in batches according to the parts by weight. The sound insulation material provided by the invention is simple to prepare, has good sound insulation performance, and overcomes the defects of poor heat resistance, high-temperature flammability, easiness in decomposition to generate toxic gas and the like in the prior art; and the weight is light, the heat resistance is good, and the environmental friendliness is good.

Description

technical field [0001] The invention relates to the field of sound-insulating materials, in particular to a sound-insulating material and its preparation method and application. Background technique [0002] Sound insulation materials refer to a class of materials, components or structures that can block sound transmission or weaken transmitted sound energy. With the continuous improvement of people's quality of life requirements, privacy protection and noise isolation are getting more and more attention. The situation of "walls have ears" and square dance "hot blood" music will stimulate conflicts between people to varying degrees. Therefore, How to continuously improve the sound insulation performance of materials has become a hot research field. [0003] At present, sound insulation materials are used in many noisy places, such as KTV, bars, chess and card rooms, etc.; even some real estate developers have begun to use sound insulation materials in large quantities in or...
