Environment-friendly rubber sound insulation building material and preparation method thereof

Abstract

The invention discloses an environment-friendly rubber sound-insulating building material, which comprises the following raw materials in parts by weight: 50-60 parts of isoprene rubber, 20-30 parts of fluorosilicone rubber, 3-5 parts of heat stabilizer, and 0.5-0.9 parts of crosslinking agent , 5-9 parts of rare earth oxide filler, 4-8 parts of glass microspheres, 3-5 parts of vulcanizing agent PDM, 2-4 parts of silane coupling agent, 6-10 parts of ore powder. The sound-insulating building material of the present invention has excellent sound-insulating performance and good waterproof effect, is more compact in structure than traditional non-woven materials, has superior sound-insulating and noise-reducing effects, has good mechanical properties, and has strong weather resistance; meanwhile, the preparation method of the present invention , the material cost is low, the raw material is easy to obtain, and the process is simple, easy to operate and realize industrial production, and has high practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly rubber sound-insulating building material and a preparation method thereof. Background technique [0002] Now, with the continuous acceleration of urbanization, noise pollution is becoming more and more serious. In order to effectively cut off noise, the usual solution is to use soundproofing materials. Existing sound insulation materials are generally cement concrete, glass panels, etc., these sound insulation and so on. The sound insulation effect of these sound insulation materials is not very good, so the usual solution is to increase the thickness of the sound insulation materials. The problem caused by this is that the quality of the sound insulation material is too heavy, the cost is too high, and the installation process is very inconvenient. Polypropylene-based composite non-woven materials made by meltblown method have become a kind...

AI Technical Summary

Problems solved by technology

The problem caused by this is that the quality of the sound insulation material is too heavy, the cost is too high, and the installation process is very inconvenient.

Polypropylene-based composite non-woven materials made by meltblown method have become a kind of sound-absorbing materials widely used in automotive interiors due to their ultra-fine fiber structure, simple and efficient production, non-toxic and harmless, etc. Most of these materials have loose structures , the smooth fiber outer layer reduces the specific surface area of ​​the material, which shortens the attenuation and conversion time of the sound wave in the material, and cannot achieve a satisfactory sound absorption effect. In actual use, the noise reduction effect is often improved by increasing the thickness of the material At the same time, the finished product has disadvantages such as easy deformation, poor resilience, easy to generate static electricity, and poor heat resistance.
