Description

A kind of glass microballoon lightweight sound barrier and preparation method thereof
Technical field
The present invention relates to a kind of preparation method of non-metal sound barrier, especially a kind of system of glass microballoon lightweight sound barrier Preparation Method.
Background technique
With the development of national economy, also in development at full speed, that amplifies out therefrom makes an uproar for the construction of railway and road Sound problem is also increasingly unexpected.Solving the common method of noise problem at present is to build sound barrier, and sound barrier is broadly divided into two kinds, gold Belong to sound barrier and non-metal sound barrier, metal sound barrier price general charged is higher, and non-metal sound barrier at this stage is generally existing heavy It measures and to install inconvenient problem greatly, sound barrier is prepared using light high strength concrete in the present invention.High-strength light coagulation Soil, which refers to, is not more than 1950 kg/m3 using the dry apparent density that high-strength lightweight, normal sands, cement and water etc. are formulated, by force Degree is the lightweight concrete of LC30 or more.It is high-strength light that the preparation key of light aggregate concrete is that the performance indicator of light-weight aggregate meets The requirement of matter concrete rough aggregate, influence of the natural and industrial waste light-weight aggregate due to forming environment, so selection is artificial Light-weight aggregate glass microballoon and haydite.Glass microballoon and haydite are light, while internal containing the hole being largely connected to, and can effectively inhale Acoustic noise.Glass microballoon is a kind of new material that one kind developed in recent years is widely used, performance is special.The product by Borosilicate raw material is process through high-tech, has light, low thermally conductive, higher intensity, good chemical stability and suction The advantages that acoustic performance.Furthermore glass microballoon uses colorful glass microbead, so that sound barrier generation is possessed different colors, overcomes colour Single drawback keeps product beautiful;Secondly night glass microballoon sound barrier can under light-illuminating it is reflective, have certain police It is shown as using, while can also act as billboard.
Summary of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide it is a kind of it is light-weight, intensity is high, easy for installation Glass microballoon lightweight sound barrier and preparation method thereof.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
A kind of glass microballoon lightweight sound barrier, is mainly made of following raw material: ordinary portland cement, river sand, silicon Ash, glass microballoon, haydite and high efficiency water reducing agent.
It further, include: ordinary portland cement 990kg, river sand, silicon ash 110kg, glass in every cube of sound barrier 160 ~ 190kg of glass microballon, 250 ~ 280kg of haydite, high efficiency water reducing agent additional amount are the 1.0 ~ 1.7% of ordinary portland cement total amount; The ratio of mud 0.17 ~ 0.19.
Portland cement, river sand and silicon ash are first carried out dry stirring by the preparation method of above-mentioned glass microballoon lightweight sound barrier, It stirs evenly, glass microballoon and haydite is then added and carries out dry stirring, stirs evenly, while high efficiency water reducing agent is added to the water mixed With stir into uniform liquid, then uniform liquid is added in the dry mixture stirred evenly, carries out wet is stirred until homogeneous;Mixing Uniform material pours into mounted mold, vibrates, and compaction moulding is to get arriving the sound barrier.
The utility model has the advantages that compared with prior art, sound barrier of the present invention is to be process by borosilicate raw material through high-tech, Have many advantages, such as light, low thermally conductive, higher intensity, good chemical stability and sound absorbing performance.Using glass of the present invention The formula of glass microballon lightweight sound barrier, product sound absorbing performance is good, acoustic absorptivity be 0.73 or more, compression strength be 48.3MPa with On, slump can be down to 149mm.Sound barrier of the present invention is light-weight, intensity is high, easy for installation, while glass microballoon is Colored, it can have decorative effect, keep product beautiful.At night, it is also used as alarming device, while can also act as wide Accuse board.Fatigue is prevented, is indicated, visual impact.
