Problems solved by technology

Traditional sound insulation materials are very bulky, have a narrow range of application, and poor processability, and traditional sound insulation products only distinguish between high-frequency noise and low-frequency noise, which cannot fully block the noise of each frequency. The noise-proof interlayer prepared by the present invention The composite material board is composed of three layers of boards. The self-made microporous resin board is used in the center of the composite material board for the noise-proof barrier, so that the material has good sound insulation effects in the low-frequency, intermediate-frequency and high-frequency regions.

Abstract

The invention provides a preparation method of a noise-proof interlayer composite material board. The preparation method comprises the following preparation steps: (1) uniformly mixing epoxy acrylic resin, belta-hydroxyethyl methacrylate, 2-ethyl-4-methyl imidazole, epoxidized soybean oil and a mixed curing agent to obtain a casting body; (2) paving wetted industrial salt particles in a mold, compacting, permeating the casting body into salt particle gaps after pre-heating and temperature rise, de-molding and removing the salt particles to obtain a micro-porous resin sheet; (3) uniformly mixing unsaturated polyester resin, dimethyl phthalate and benzoyl peroxide, casting to a glass fiber fabric and drying to obtain a glass fiber composite material; (4) clamping the micro-porous resin sheetin the two glass fiber composite materials and tightly wrapping with a casing to obtain the noise-proof interlayer composite material board. The noise-proof interlayer composite material board prepared with the preparation method provided by the invention is strong in machinability, capable of effectively blocking noise, light in weight, easy to transport and capable of meeting the needs of different occasions.

Description

technical field [0001] The invention relates to the field of materials, in particular to a preparation method of a noise-proof interlayer composite material board. Background technique [0002] With the development of industrialized production, all kinds of noise pollution are becoming more and more serious, which not only affects the life of production equipment, but also affects the health and quality of life of workers. People's requirements for vibration reduction and noise reduction are increasing day by day. To prevent noise pollution, noise can be blocked by sound insulation materials. The sound insulation performance of sound insulation materials is closely related to the performance of the material itself. Traditional sound insulation materials are very bulky, have a narrow range of application, and poor processability, and the traditional sound insulation products only distinguish between high-frequency noise and low-frequency noise, which cannot fully block the no...
