Sound-absorbing and sound-insulating mortar and preparation method thereof

Abstract

The invention discloses sound-absorbing and sound-insulating mortar and a preparation method thereof. The technical scheme is that the sound-absorbing and sound-insulating mortar is prepared from the following raw materials in parts by weight: 60 parts of cement, 45 parts of quartz sand, 18-30 parts of sound-insulating filler, 21-32 parts of sound-absorbing filler and 9-21 parts of additive, The sound-insulating filler comprises cellulose, acrylate and epoxy resin. The weight ratio of the cellulose, the acrylate and the epoxy resin are as follows: 5 -9 parts of cellulose, 6 -10 parts of acrylate and 7 -11 parts of epoxy resin. The sound-absorbing filler comprises perlite, glass beads, polyphenyl particles, perlite, glass beads and polyphenyl particles. The weight ratio of the perlite, the glass beads and the polyphenyl particles are as follows: 6 -10 parts of perlite, 7 -10 parts of glass beads and 8 -12 parts of polyphenyl particles. The sound-absorbing and sound-insulating mortar and the preparation method thereof have the beneficial effects that the mortar can block a part of sound while greatly absorbing the sound, the sound-insulating effect of the mortar is improved, and the living environment of people is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of mortar, in particular to a sound-absorbing and sound-insulating mortar and a preparation method thereof. Background technique [0002] Mortar is a bonding substance used in building bricks, which is composed of a certain proportion of sand and cementing materials plus water. With the improvement of living standards, people pay more and more attention to the sound insulation performance of buildings, so the requirements for buildings are getting higher and higher. At present, sound insulation mortar is often used in construction projects. Sound insulation mortar is made of cement, quartz sand, The sound insulation filler and admixture are configured according to the quantity, and it is an ideal sound insulation material for construction. [0003] The prior art has the following deficiencies: most of the existing sound insulation mortars only have specific sound insulation functions, but there is still sou...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the present invention provides a sound-absorbing and sound-insulating mortar and a preparation method thereof, by uniformly mixing cement, quartz sand, sound-insulating filler, sound-absorbing filler and admixture at the same time to obtain the sound-insulating mortar to solve the problem of existing sound-insulating mortar During the sound insulation process, there is still sound that can be transmitted, and the sound insulation effect is not good. After construction, the ideal sound insulation effect will not be achieved, which will affect the living environment of people.
