Problems solved by technology

However, the sound insulation effect of the current light-body bricks is far from achieving the purpose of silence. Taking ordinary bricks and the current mainstream light-body bricks ALC bricks as examples, after testing, the sound-absorbing effect of ordinary bricks is only about 10%. Although the sound absorption effect of the body reaches about 70%, it still cannot meet the needs of some places with particularly high requirements for sound insulation, such as stadiums, conference rooms or entertainment places.
Taking entertainment venues as an example, now the general compartment is made of wood as a bracket, clamped by plywood on both sides, foam board is used in the middle for sound insulation, and finally the exterior is sealed with gypsum. The material cost is relatively expensive, and due to the large amount of construction, not only manual Expensive, long construction time, and fire hazard

Embodiment 1

[0024] Embodiment 1: preparation bulk density ratio 200kg / m 3 soundproof brick body

[0025] 1) After mixing 0.7kg of protein foaming agent and 42kg of water, a high-pressure foaming machine is used to make foam. The foam is stable and the diameter of the foam is uniform and between 0.1 and 1mm;

[0026] 2), the cement of 180kg weight ratio, the fly ash of 20kg and 78kg water are stirred together and mixed into slurry;

[0027] 3) Inject the foam into the slurry through high pressure;

[0028] 4), under the delivery of the high-pressure pump, pour the foamed slurry into the mold;

[0029] 5) Under the condition of natural maintenance, let the soundproof brick body shape;

[0030] 6) Take off the mold to get the finished soundproof brick body.

Embodiment 2

[0031] Embodiment 2: preparation density ratio 350kg / m 3 soundproof brick body

[0032] 1) After mixing 0.55kg of polymer foaming agent and 33kg of water, a high-pressure foaming machine is used to make foam. The foam is stable and the diameter of the foam is uniform and between 0.1 and 1mm;

[0033] 2), the cement of 280kg weight ratio, the fly ash of 70kg and 210kg water are stirred together and mixed into slurry;

[0034] 3) Inject the foam into the slurry through high pressure;

[0035] 4), under the delivery of the high-pressure pump, pour the foamed slurry into the mold;

[0036] 5) Under the condition of natural maintenance, let the soundproof brick body shape;

[0037] 6) Take off the mold to get the finished soundproof brick body.

Embodiment 3

[0038] Embodiment 3: preparation density ratio 400kg / m 3 soundproof brick body

[0039] 1) After mixing 0.5kg of protein foaming agent and 20kg of water, a high-pressure foaming machine is used to make foam. The foam is stable and the diameter of the foam is uniform and between 0.1 and 1mm;

[0040] 2), the cement of 280kg weight ratio, the fly ash of 120kg and 240kg water are stirred together and mixed into slurry;

[0041] 3) Inject the foam into the slurry through high pressure;

[0042] 4), under the delivery of the high-pressure pump, pour the foamed slurry into the mold;

[0043] 5) Under the condition of natural maintenance, let the soundproof brick body shape;

[0044] 6) Take off the mold to get the finished soundproof brick body.

Abstract

The present invention discloses process of making sound insulating brick, and belongs to the field of building material technology. The process includes the following steps: preparing foam with foaming agent and water; preparing slurry with cement, fly ash and water in certain proportion; pressurizing the foam into the slurry; pumping the foamed slurry with a high pressure pump to depositing mold; naturally curing and demolding to obtain product. By means of Heln. Holtn resonance principle, the sound insulating brick can eliminate sound wave through absorbing vibrating energy. The process is simple and low in cost, and may have different molds adopted.

Description

1. Technical field [0001] The invention relates to a preparation method of a building material, in particular to a preparation method of a building brick material with good sound insulation effect. 2. Background technology [0002] The structure of existing buildings is mainly divided into brick-concrete structure and frame structure. No matter what kind of structure, brick body is needed as the filling of the main body of the building. At present, there are many forms of brick body, mainly ordinary brick body and light body The brick body, in which the light body brick body is usually a variety of hollow bricks, can play a better sound insulation effect than ordinary brick bodies. However, the sound insulation effect of the current light-body bricks is far from achieving the purpose of silence. Taking ordinary bricks and the current mainstream light-body bricks ALC bricks as examples, after testing, the sound-absorbing effect of ordinary bricks is only about 10%. Although ...
