Abstract
The invention provides a sandstone microbead environment-friendly acoustical ceiling, and belongs to building decoration sound absorption materials. The sandstone microbead environment-friendly acoustical ceiling is composed of four parts, round sand grains or hollow glass microbeads or closed cell perlite and a binding agent are mixed to be pressed to form a base layer, and a gridding cloth or glass fiber mat framework layer is arranged on the base layer. A hollow glass microbead layer is arranged on the framework layer, and a decoration effect layer is arranged on the hollow glass microbead layer. The first three layers are tightly pressed in a mould, after water evaporates, and the binding agent is solidified, natural pores are formed in a plate, and a sound absorption effect is achieved. Then natural white sand grains and the binding agent or coatings or paint are mixed to process the decoration effect layer, and the porosity of a face layer of the decoration effect layer is 15%-60%. While attractiveness and elegance are achieved, the sound absorption effect is also achieved. The specific flow resistance rate is 800 Pa.s/m-180 Pa.s/m after all the layers are put together, different grain diameters are used according to different frequency sound absorption demands, and it is guaranteed that excellent absorption is achieved in high, medium and low frequency.
Description
Technical field:
The present invention is multi-functional sandstone microballon environmental protection acoustical ceiling, belongs to the sound absorption material field of building decoration and fitment, acoustics design, noise reduction.
Background technology:
Ceiling is one of sound absorption material, also be sound absorption reduction in building decoration and fitment, the important means of building acoustics design, building acoustical ceiling kind on existing market is also a lot, ordinary smallpox plate is mainly with rock cotton board, mineral wool board, the cotton plate of glass is main, also has perforation composite class acoustical ceiling, these acoustical ceilings all cut both ways, the material that combination property is all good is few, be difficult to the demand adapting to modern architecture development, multi-functional sandstone microballon environmental protection acoustical ceiling overcomes the drawback of existing market sound absorbent for building, reach and draw materials conveniently, sound absorbing capabilities is controlled, frequency-adjustable, sound absorption coefficient is high, fire prevention A level, discharge without any pernicious gas, be not afraid of humidity, weatherability is strong, the comprehensive splendid acoustical ceiling such as non-secondary pollution.
Summary of the invention:
The object of this invention is to provide a kind of novel sandstone microballon environmental protection acoustical ceiling.
This sandstone microballon environmental protection acoustical ceiling is by basal layer (1), casing play (2), hollow glass micropearl layer (3) and decorative effect layer (4) four incorporating aspects form, wherein basal layer (1) to be mixed with adhesive by circle sand grains or hollow glass micropearl mixes with adhesive or closed perlite forms basal layer (1) with adhesive mixing compacting, basal layer (1) is provided with grid cloth or glass fibre mat casing play (2), casing play (2) is provided with hollow glass micropearl layer (3), on hollow glass micropearl layer, (3) are provided with decorative effect layer (4).
Circle sand grains mixes with adhesive or hollow glass micropearl mixes with adhesive or closed perlite forms basal layer with adhesive mixing compacting, and the particle diameter of its circle sand grains, hollow glass micropearl, closed perlite is 20 order to 80 orders, and surface density is at 3kg/m
2-10kg/m
2, be 600Pas/m-1600Pas/m than flow resistance value; Grid cloth or glass fibre mat casing play, its grid cloth or glass mat are pulling force in order to strengthen acoustical board and intensity, and play skeleton function, surface density is 0.04kg/m
2-0.2kg/m
2; Hollow glass micropearl layer, be glued to mix by glass hollow pearl and adhesive to be pressed on casing play, not only alleviating the weight of ceiling but also have intensity, is 200Pas/m-800Pas/m than flow resistance value; Decorative effect layer, to mix with adhesive with natural white sand grain or coating or material of paint, surface layer has micropore to reach sound absorption, there is decorative effect again, different aperture decorative effect layer is adopted when absorbing different frequency, percent opening is 15%-60%, and by after 4 incorporating aspects, it is 800Pas/m-1800Pas/m than flow resistance value to sandstone microballon environmental protection acoustical ceiling.
The round sand grains of basal layer or hollow glass micropearl or closed perlite, the glass microballoon of hollow glass micropearl layer, the regular change of natural its particle diameter of white sand grain of decorative effect layer; different acoustically effectives can be reached; when many absorption low frequencies, basal layer, hollow glass micropearl layer are just with small particle diameter 60 order to 80 order, and when absorbing high frequency, basal layer, hollow glass micropearl layer will use Large stone 20 order to 40 order.
Accompanying drawing illustrates:
Accompanying drawing is sandstone microballon environmental protection acoustical ceiling structural representation of the present invention
In the drawings: 1 to be mixed with adhesive by circle sand grains or hollow glass micropearl mixes with adhesive or closed perlite forms basal layer with adhesive mixing compacting, 2 grid cloths or glass fibre mat casing play, 3 hollow glass micropearl layers, 4 decorative effect layers.
Detailed description of the invention:
This sandstone microballon environmental protection acoustical ceiling is formed by basal layer (1), casing play (2), hollow glass micropearl layer (3) and decorative effect layer (4) four incorporating aspects.
The first step: choose equal particle diameter circle sand grains or hollow glass micropearl or closed perlite, select epoxy resin or polyurethane adhesive; Second step: be placed on after mixing in the mould of standard and compress compacting; 3rd step: grid cloth or glass fibre mat are cut into specification and are placed on basal layer; 4th step: be placed on top after being mixed with adhesive by the hollow glass micropearl chosen and compress, each layer can stick together after water evaporates, and different holes appears in each layer, plays the effect of sound absorption; 5th step: to mix with adhesive with natural white sand grain after drag mode or coating or paint, carry out surface layer process, surface layer percent opening is between 15%-60%, adopts different aperture decorative effect layer when absorbing different frequency.
