Description
Technical field
The present invention relates to the preparation method of a kind of non-metal sound barrier, the system of a kind of glass microballoon lightweight sound barrier
Preparation Method.
Background technology
Along with the construction of the development of national economy, railway and road is also in development at full speed, that amplifies out therefrom makes an uproar
Sound problem is the most unexpected.The common method solving noise problem at present is to build sound barrier, and sound barrier is broadly divided into two kinds, gold
Belonging to sound barrier and non-metal sound barrier, metallic sound barrier price general charged is higher, and the non-metal sound barrier of present stage generally exists weight
Amount makes greatly to install inconvenient problem, uses light high strength concrete to prepare sound barrier in the present invention.High-strength light coagulation
Soil refers to utilize the formulated dry apparent densities such as high-strength lightweight, normal sands, cement and water to be not more than 1950 kg/m3, by force
Degree is the lightweight concrete of more than LC30.The preparation of light aggregate concrete it is critical only that the performance indications of light-weight aggregate meet high-strength gently
The use requirement of matter concrete rough aggregate, natural and industrial waste light-weight aggregate is due to the impact of soil boy structure, so selecting artificial
Light-weight aggregate glass microballoon and haydite.Glass microballoon and haydite light weight, the most internal hole containing a large amount of connections, can effectively inhale
Acoustic noise.A kind of of many uses, a kind of new material that performance is special that glass microballoon is that development in recent years is got up.This product by
Borosilicate raw material processes through high-tech, has light weight, low heat conduction, higher intensity, good chemical stability and suction
The advantages such as acoustic performance.In addition glass microballoon uses colorful glass microbead, makes sound barrier produce and has different colors, overcomes colour
Single drawback, makes product attractive in appearance；Secondly night glass microballoon sound barrier can at light-illuminating under reflective, there is certain police
It is shown as use, can also act as billboard simultaneously.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of lightweight, intensity is high, easy for installation
Glass microballoon lightweight sound barrier and preparation method thereof.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that:
A kind of glass microballoon lightweight sound barrier, is mainly made up of following raw material: Portland cement, river sand, silicon ash, glass
Glass microballon, haydite and high efficiency water reducing agent.
Further, every cube of described sound barrier includes: Portland cement 990kg, river sand, silicon ash 110kg, glass
Glass microballon 160 ~ 190kg, haydite 250 ~ 280kg, high efficiency water reducing agent addition is the 1.0 ~ 1.7% of Portland cement total amount；
The ratio of mud 0.17 ~ 0.19.
The preparation method of above-mentioned glass microballoon lightweight sound barrier, first carries out dry stirring by portland cement, river sand and silicon ash,
Stir, be subsequently adding glass microballoon and haydite carries out dry stirring, stir, high efficiency water reducing agent is added to the water mixed simultaneously
With stir into uniform liquid, then uniform liquid is added in the dry mixture that stirs, carries out wet being stirred until homogeneous；Mixing
Uniform material is poured in mounted mould, vibrates, and compaction moulding i.e. obtains described sound barrier.
Beneficial effect: compared with prior art, sound barrier of the present invention is to be processed through high-tech by borosilicate raw material,
There is the advantages such as light weight, low heat conduction, higher intensity, good chemical stability and sound absorbing capabilities.Use glass of the present invention
The formula of glass microballon lightweight sound barrier, product sound absorbing capabilities is good, and acoustic absorptivity is more than 0.73, comprcssive strength be 48.3MPa with
On, slump can be down to 149mm.Sound barrier of the present invention is lightweight, intensity is high, easy for installation, glass microballoon is simultaneously
Colored, can have decorative effect, make product attractive in appearance.At night, it is also possible to as alarming device, can also serve as wide simultaneously
Accuse board.Prevent fatigue, indicate, visual impact.
