Abstract

The invention relates to a heat-preservation and sound-absorption paste material for a roof and a preparation method thereof. The heat-preservation and sound-absorption paste material is prepared from the following components in parts by mass: 50-60 parts of water, 2-5 parts of an organic cementing material, 1-3 parts of a silicate solution, 3-5 parts of an auxiliary agent, 5-20 parts of coarse Poraver beads, 5-10 parts of fine Poraver beads, 5-25 parts of hollow glass beads, 1-15 parts of fibers, 2-6 parts of filling powder and 1-3 parts of an additive, the bulk density of the coarse Poraver beads is 110-150kg/m < 3 >, and the particle size D90 of the coarse Poraver beads is less than or equal to 2mm; the bulk density of the fine Poraver beads is 180-220 kg/m < 3 >, and the particle size D90 of the fine Poraver beads is 0.3 mm. The invention has the advantages of high sound absorption coefficient, wide sound absorption frequency band, fast construction, seamless surface, safety, environmental protection and the like.

Description

technical field [0001] The invention relates to the field of building thermal insulation and sound absorption materials, in particular to a thermal insulation and sound absorption spray paste for roofs and a preparation method thereof. Background technique [0002] With the advancement of science and technology, the creation and use of various mechanical equipment has brought prosperity and progress to human beings, but also produced more and more noise. Noise will not only cause hearing damage, but also induce a variety of cancer-causing and fatal diseases, harm the human cardiovascular system, affect the human nervous system, make people irritable, irritable, affect sleep, cause fatigue, and interfere with people's mental health. Life and work affect people's quality of life. The indoor surface of the building includes the ground, wall and roof. If only hard and dense stone, plaster, and wood are used for decoration, it will produce strong reflection of sound waves, which...
