Abstract
The utility model discloses a light weight mineral wool stave which comprises a basal body made of pure mineral wool material. Perlite with certain particle size is distributed in the basal body. As the perlite particles are distributed on the basal body made of the pure mineral wool in the light weight mineral wool stave of the utility model, not only is the weight of the mineral wool stave reduced, but also performances of the mineral wool stave on acoustic absorption, heat insulation and fireproof aspect are improved with the acoustical absorptivity equal to or more than 0.55.
Description
Technical field
The utility model relates to a kind of mineral wool board.
Background technology
Mineral wool board is a kind of novel constructional materials, because of it has sound absorption, excellent characteristic such as heat insulation, fire-resistant is widely used on the ceiling of building.The mineral wool board that adopts substantially all is made up of pure mineral wool at present, and is therefore relative still heavier on weight.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of light mineral wool slab, compares with pure mineral wool board, can reduce the weight of mineral wool board, and has improved acoustically effective greatly.
A kind of light mineral wool slab of the present utility model comprises: comprise the matrix of being made by pure mineral wool material, be distributed with the perlite with certain particle diameter in described matrix.
Preferably, described perlite is evenly distributed in the described matrix.
Preferably, described perlitic particle diameter is the open cell type perlite.
Preferably, described perlitic weight accounts for 5～35% of described matrix and perlite gross weight, and described percentage is weight percentage.
Preferably, described perlitic particle diameter is less than 2mm.
The utility model light mineral wool slab is owing to be distributed with perlite particle on the matrix of being made up of pure mineral wool, so not only reduced the weight of mineral wool board, but also improved the sound-absorbing of mineral wool board, the performance of heat insulation, fire-resistant aspect, sound absorption coefficient 〉=0.55.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises: by pure mineral wool material matrix of making 1 and the perlite 2 with certain particle diameter, perlite 2 is evenly distributed in the matrix 1.Perlitic particle diameter is preferably less than 2mm, and the particle diameter of perlite 2 is the open cell type perlite.The weight of perlite 2 accounts for 5～35% (percentage by weights) of matrix 1 and perlite 2 gross weights, so not only reduced the gross weight of pure mineral wool board, the reduction amplitude can reach 10～30% (percentage by weights), and existing pure mineral wool board is compared, at sound-absorbing, aspect of performance aspect heat insulation, fire-resistant the raising of certain amplitude, sound absorption coefficient 〉=0.55 are arranged.
In addition,, at first granulated wool, perlite, sizing agent and water are evenly mixed according to a certain percentage, mixed material is joined in the granulated wool step of preparation process of pure mineral wool board then by the technology of premix in order to obtain the utility model.Like this, just can access the light mineral wool slab that in matrix 1, is evenly distributed with perlite 2.
Claims (5)
1, a kind of light mineral wool slab comprises the matrix of being made by pure mineral wool material, it is characterized in that, is distributed with the perlite with certain particle diameter in described matrix.
2, a kind of light mineral wool slab as claimed in claim 1 is characterized in that, described perlite is evenly distributed in the described matrix.
