Embodiment 1

[0015] Such as figure 1 The GRC sound-absorbing and insulating body sound barrier of a new type of material, the inner cavity of the sound barrier is a sound-absorbing material cavity (1) at the front, and an air cushion cavity (2) at the rear. It is an alkali-resistant glass fiber reinforced cement component, which contains the following components (KG): 50 cement, 47 sand, 3 fibers, and an appropriate amount of water.

[0016] Preparation method: mix the above-mentioned components for later use, make a mold, and then carry out spray-casting molding.

Embodiment 2

[0018] Such as figure 1 The GRC sound-absorbing and insulating body sound barrier of a new type of material, the inner cavity of the sound barrier is a sound-absorbing material cavity (1) at the front, and an air cushion cavity (2) at the rear. It is an alkali-resistant glass fiber reinforced cement component, and the alkali-resistant glass fiber reinforced cement component contains the following components (KG): 40 cement, 40 sand, 2 alkali-resistant glass fibers, and an appropriate amount of water.

[0019] Preparation method: mix the above-mentioned components for later use, make a mold, and then carry out spray-casting molding.

Embodiment 3

[0021] Such as figure 1 The GRC sound-absorbing and insulating collective sound barrier of a new type of material, the inner cavity of the sound barrier is a sound-absorbing material cavity (1) at the front, and an air cushion cavity (2) at the rear. (3) Reliefs are provided at all parts: shutters (4) are also provided at the outer end of the sound barrier.

[0022] The raw screen body is an alkali-resistant glass fiber reinforced cement component, and the alkali-resistant glass fiber reinforced cement component contains the following components (KG): 60% cement, 55% sand, 4% alkali-resistant glass fiber, and an appropriate amount of water.

[0023] Preparation method: mix the above-mentioned components for later use, make a mold, and then carry out spray-casting molding.

[0024] This kind of sound barrier has the characteristics of sound absorption, good sound insulation effect, beautiful decoration and light weight.

Abstract

The present invention discloses a GRC sound-absorbing sound-insulating coenosarcs sound screen made of new-type material. The front portion of inner cavity of said sound screen is sound-absorbing material cavity, and its rear portion is air cushion cavity. The described sound screen body is alkali-proof glass fibre reinforced cement component whose composition includes (by weight portion) 40-60 portions of cement, 40-55 portions of sand, 2-4 portions of alkali-proof glass fibre and proper quantity of water.

Description

technical field [0001] The invention relates to a sound-absorbing and sound-insulating product of a type of material, in particular to a GRC sound-absorbing and insulating composite sound barrier of a new type of material and a preparation method thereof. Background technique [0002] At present, there is a glass fiber reinforced cement (GRC for short) on the market, which is generally used in building materials. It is made of alkali-resistant glass fiber, cement, and sand. After more than 30 years of improvement, this product has high strength and durability. Strong, lightweight and other advantages, it has been widely used in the field of construction and as noise barriers on expressways and viaducts. However, due to the limitations of the process, its sound absorption and sound insulation effects are not good. Contents of the invention [0003] The object of the present invention is to provide a sound-absorbing and sound-insulating product of a new type of material, es...
