Problems solved by technology

[0002] In the process of urban development, rail transit is indispensable, and its noise pollution also seriously affects the lives of residents. Although traditional materials have solved the problem of sound absorption and sound insulation, they also have sound absorption and sound insulation that can reach A-level fire prevention. There are few fireproof lightweight water-permeable materials. The present invention uses inorganic high-temperature-resistant materials as aggregates, Portland cement and active admixtures as cement materials, and fiber as the most reinforced material to invent a sound-absorbing, sound-insulating, fire-proof, light-weight, water-permeable material.

Abstract

A railway traffic sound-absorption and -insulation fireproof light-weight water-permeable material and a preparation method thereof. The invention belongs to the environment-protective technical field of fireproofing, sound absorption and insulation, and noise reduction in railway traffic. The material is prepared with calcined shale ceramic granules as an aggregate and Portland cement and quick-hardening sulphoaluminate cement as cementing materials with various additives. The aggregate in equal granular size, the Portland cement and quick-hardening sulphoaluminate cement as the cementing materials, rubber powder, polypropylene fiber, silicon dioxide micro-powder and a polycarboxylate water reducing agent are mixed to prepare a material, wherein the material includes, by weight, 50-80 parts of the ceramic granule in equal granular size, 13-40 parts of the Portland cement, 1-15 parts of the quick-hardening sulphoaluminate cement, 0-8 parts of the rubber powder, 0-5 parts of the polypropylene fiber, 0-8 parts of the silicon dioxide micro-powder, 0.1-0.5 parts of the polycarboxylate water reducing agent and 4-10 parts of water. When being used, the material just needs to be stirred uniformly with tap water for carrying out die casting or pave casting.
