Abstract

The invention relates to the technical field of building materials, and in particular, relates to a sound-insulation fireproof building material comprising the following raw materials in parts by weight: 45-60 parts of composite cement, 30-35 parts of graded aggregate, 15-20 parts of a sound insulation component, 3-5 parts of a fireproof component, 1-2 parts of a water reducing agent, 0.5-1.8 parts of a thickening time control component, 2-4 parts of an expansion component, 0.1-0.2 part of a foaming agent, 0.2-0.4 part of a defoaming agent and 0.02-0.04 part of a water retaining agent, whereinthe thickening time control component consists of sodium sulfate, sodium gluconate and boric acid in a mass ratio of (2-4):(0.5-1):(0.6-0.8). The composite cement, the graded aggregate, the sound insulation component, the fireproof component, the water reducing agent, the thickening time control component, the expansion component, the foaming agent, the defoaming agent and the water retaining agent are reasonably proportioned, and all the raw materials are matched with one another, so that the sound-insulation fireproof building material has the advantages of fire prevention, sound insulation, high mechanical strength and short setting time, and has important significance for development of the concrete industry.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a soundproof and fireproof building material. Background technique [0002] With the rapid development of the city, the scale of the city's buildings is also gradually expanding. Building construction is inseparable from building materials. As the construction industry consumes natural resources, high energy, and large emissions of exhaust gas and dust, energy conservation and environmental protection have become the top priority. [0003] There are many types of building materials in the prior art. In recent years, the demand for multifunctional building materials with fire prevention, heat preservation and sound insulation has been increasing. There are problems of low mechanical strength of building materials and long setting time, which cannot meet people's needs. [0004] For this reason, a kind of sound insulation and fire prevention building material is propose...
