Abstract
The present invention relates to a kind of magnesite acoustic tile, being composited with aggregate 3 4:1 by magnesia cement, described magnesia cement includes the component of following proportioning by weight: magnesia unslacked 70 80 parts, magnesium chloride solution 20 35 parts, 0.3 0.5 parts of magnesium sulfate, water repellent agent 0.2 0.4 parts, reinforcing fibre 0.3 0.5 parts.The present invention is by rationally selecting magnesia cement and the proportioning of aggregate, forcing press and magnesia cement gelling is used to make between aggregate, have good cohesive force, bond effect is good, overall performance is excellent, and the acoustic tile formed has excellent anti-acoustic capability, pollution-free, intensity is high, excellent durability, technique are simple and convenient to operate, the advantage such as with low cost.
Description
Technical field
The invention belongs to building material technical field, relate to a kind of acoustic tile, especially relate to a kind of magnesite acoustic tile.
Background technology
Along with the continuous enhancing of people's environmental consciousness, problem of noise pollution increasingly comes into one's own.In recent years, due to sharply increasing of highway, urban elevated road and the fast development of urban light rail construction and urban automobile quantity, traffic noise problem is on the rise, and has become as and affects one of people's lives pollution the most serious, widest.In the measure of various preventing and treating traffic pollutions, setting up road noise barrier is a kind of effective ways.
Existing sound barrier mainly includes machine sound barrier, metallic sound barrier and inorganic sound barrier three class.Although organic sound barrier and metallic sound barrier have simple installation, be easy to maintenance and can the advantage such as scale manufacturing, but the shortcoming that its cost is high and coordination of landscape is poor, corrosion resistance requirement is high is also clearly.Although inorganic sound barrier is pollution-free, low cost, but its volume is big, transport inconvenience.Acoustic tile masonry formula sound barrier, as one of sound barrier important form reducing traffic noise, has all advantages of inorganic sound barrier, little additionally, due to its volume, transports, builds by laying bricks or stones and conveniently widely applied.Acoustic tile in the market mostly is plane formula or ripple is facial so that there is the sudden change of acoustic impedance between acoustic tile and air, bigger sound reflecting occurs, thus reduces the sound absorbing capabilities of acoustic tile.
Summary of the invention
For solving the deficiencies in the prior art, it is an object of the invention to provide that a kind of production technology is simple and convenient to operate, anti-acoustic capability is good and the magnesite acoustic tile of easy construction.
For reaching above-mentioned purpose, the present invention is achieved by the following technical solutions.
A kind of magnesite acoustic tile, it is characterised in that include that magnesia cement and aggregate, described magnesia cement are 3-4:1 with the weight ratio of aggregate.
Described magnesia cement is made up of following parts by weight: magnesia unslacked 70-80 part, magnesium chloride solution 20-35 part, magnesium sulfate 0.3-0.5 part, water repellent agent 0.2-0.4 part, reinforcing fibre 0.3-0.5 part.
Described magnesium chloride solution Baume degrees is 24-28 degree/20 DEG C.
Described water repellent agent is mixed by weight 1:1 with styrene-acrylic emulsion by phosphoric acid.Styrene-acrylic emulsion, i.e. styrene-acrylate emulsion, be to be obtained through emulsion copolymerization by styrene and acrylate monomer.
Described reinforcing fibre is polypropylene fibre, a length of 6-9mm.
Described aggregate is one or more in expanded perlite, haydite, blast-furnace cinder, wood flour.
The particle diameter of described aggregate is 0.5-3.5mm.
Beneficial effect:Compared with prior art, it is an advantage of the current invention that:
The present invention is by rationally selecting magnesia cement and the proportioning of aggregate, and make that there is between aggregate good cohesive force by ambient pressure and magnesia cement gelling, bond effect is good, overall performance is excellent, and the acoustic tile formed has excellent anti-acoustic capability, pollution-free, intensity is high, excellent durability, technique are simple and convenient to operate, the advantage such as with low cost.
