Embodiment 1

[0011] A soundproof glass comprises the following raw materials in parts by weight: 50 parts of silicon dioxide, 2 parts of aluminum oxide, 2 parts of magnesium oxide, 5 parts of calcium oxide, 2 parts of zinc oxide, 2.25 parts of quartz sand, and 0.75 parts of vitrified microbeads.

[0012] Measure by adjusting the sound level of the loudspeaker. The sound level of the loudspeaker is adjusted to be 100dB for the outgoing sound and 90 dB for the reflected sound. When testing ordinary glass, the outgoing sound is 82dB and the reflected sound is 90 dB. When testing the glass of the present invention , the transmitted sound is 70dB, and the reflected sound is 90dB.

Embodiment 2

[0014] A soundproof glass comprises the following raw materials in parts by weight: 60 parts of silicon dioxide, 5 parts of aluminum oxide, 5 parts of magnesium oxide, 5 parts of calcium oxide, 2 parts of zinc oxide, 6 parts of quartz sand, and 2 parts of vitrified microspheres.

[0015] Measure by adjusting the sound level of the loudspeaker. The sound level of the loudspeaker is adjusted to be 100dB for the outgoing sound and 90 dB for the reflected sound. When testing ordinary glass, the outgoing sound is 82dB and the reflected sound is 90 dB. When testing the glass of the present invention , the transmitted sound is 66dB, and the reflected sound is 90 dB.

Embodiment 3

[0017] A soundproof glass comprises the following raw materials in parts by weight: 55 parts of silicon dioxide, 3 parts of aluminum oxide, 3 parts of magnesium oxide, 7 parts of calcium oxide, 3 parts of zinc oxide, 3.75 parts of quartz sand, and 1.25 parts of vitrified microbeads.

[0018] Measure by adjusting the sound level of the loudspeaker. The sound level of the loudspeaker is adjusted to be 100dB for the outgoing sound and 90 dB for the reflected sound. When testing ordinary glass, the outgoing sound is 82dB and the reflected sound is 90 dB. When testing the glass of the present invention , the transmitted sound is 60dB, and the reflected sound is 90 dB.

Abstract

The present invention discloses a sound insulation glass, which comprises the following raw materials, by weight: 50-60 parts of silica, 2-5 parts of alumina, 2-5 parts of magnesium oxide, 5-10 parts of calcium oxide, 2-5 parts of zinc oxide, and 3-8 parts of sound insulation granules, wherein the sound insulation granules are a mixture comprising quartz sand and vitrified micro-beads, and a weight ratio of the quartz sand to the vitrified micro-beads is 1-5:1. According to the sound insulation glass, in addition to the raw materials of the ordinary glass and the auxiliary agent, the sound insulation granules such as the quartz sand and the vitrified micro-beads are added, such that the sound insulation function of the glass is improved, and functions of daylighting and heat dissipating of the glass are not affected.

Description

technical field [0001] The invention relates to a sound-insulating glass, which belongs to the field of glass design. Background technique [0002] With the development of industrial production, transportation, and urban construction, as well as the increase of population density and the increase of household facilities (audio, air conditioning, television, etc.), environmental noise is becoming more and more serious, and it has become a major public hazard that pollutes the human social environment. Environmental noise pollution refers to the phenomenon that the generated environmental noise exceeds the environmental noise emission standards stipulated by the state and interferes with the normal life, work and study of others. Environmental noise pollution is a kind of energy pollution. Like other industrial pollution, it is a public hazard that endangers the human environment. Noise is localized, temporary, and multiple, which not only affects hearing, but also adversely ...
