Abstract

The invention belongs to the field of functional materials, and particularly relates to an environment-friendly rubber sound-insulation material and a preparation method thereof. The material comprises the following components in percentage by weight: 1-3% of dibenzoyl peroxide, 1-3% of silicon oxide, 5-15% of recovered epoxy resin, 5-15% of composite rare-earth oxide and the balance of silicon rubber. No abundant rare materials are used in the preparation process, so the raw material cost is lowered; and the wastes are used as the raw materials, so the material preparation method is convenient in technique and simple in process. The prepared material can effectively absorb energies, can be used in the fields of transportations, architecture, military affairs and the like, has the functions of shock resistance, impact buffering, heat insulation, sound insulation and the like, and is especially suitable to be used as a saloon car damping fin.

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to an environment-friendly rubber sound-insulating material and a preparation method thereof. Background technique [0002] CN201310244786.7 provides lightweight asphalt damping film for automobiles and a preparation method thereof. The damping film is prepared by blending petroleum asphalt, SBS, warm-mix asphalt modifier, aromatic oil, light heat-insulating and sound-absorbing materials, and inorganic fillers. 180-200 parts of 10# asphalt resin, 0-20 parts of 30# asphalt resin, 5 parts of SBS elastomer, 5-7 parts of warm mix asphalt modifier, 90-100 parts of aromatic oil, 90 parts of attapulgite, hollow glass 10 parts of microbeads, 60-80 parts of Shuangfei powder, 90-100 parts of light calcium carbonate. Applicable to the bottom of the car body, it has the advantages of light weight, shock absorption and good heat insulation and sound absorption. The damping coef...
