Abstract
The invention discloses a light-weight mineral cotton plate, which comprises the following components in percentage by weight: 5 to 30 percent of perlite, 30 to 70 percent of rock mineral cotton, 5 to 15 percent of flocculant, 3 to 10 percent of starch, 7 to 15 percent of paper, 0.2 to 1 percent of wet strength agent, 0.2 to 1 percent of sizing agent, and 2 to 15 percent of aluminum sulfate. By adding 10 to 30 percent (percentage by weight) of the perlite to a pure mineral cotton plate, the light-weight mineral cotton plate not only can lighten the weight of the mineral cotton plate with the same volume by 20 to 30 percent, but also can greatly improve the performance on sound absorption.
Description
Technical field
The present invention relates to a kind of mineral wool board.
Background technology
Mineral wool board is a kind of novel material of construction, because of it has sound absorption, excellent characteristic such as heat insulation, fire-resistant is widely used on the top ceiling of buildings.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.In addition, in order further to improve the sound absorbing capabilities of mineral wool board, industry has been done various trials, does not all have even more ideal mineral wool board to be developed out.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of light mineral wool slab, not only has lighter weight, but also has improved the performance of mineral wool board aspect sound absorption.
A kind of light mineral wool slab of the present invention comprises following component: perlite 5～30%, rock mineral wool 30～70%, flocculation agent 5～15%, starch 3～10%, paper 7～15%, Wet Strength Resin 0.2～1%, sizing agent 0.2～1%, Tai-Ace S 150 2～15%; Wherein, described per-cent is weight percentage.
Preferably, described perlite is the perforate perlite.
Preferably, described perlitic particle diameter is less than 2mm.
The present invention is by adding the perlite particle of 10～30% (weight percents) in pure mineral wool board, not only can make the mineral wool board weight saving 20～30% of equal volume, and the performance aspect sound absorption is greatly improved.
Description of drawings
Fig. 1 is the rotation batch mixing mechanism that premix adopted;
Fig. 2 be among Fig. 1 A-A to view.
Embodiment
Embodiment 1
At first, take by weighing each material according to perlite 5%, rock mineral wool 70%, flocculation agent 5%, starch 5%, paper 5%, Wet Strength Resin 1%, sizing agent 1%, Tai-Ace S 150 8%, wherein, each percentages of ingredients is weight percentage, and flocculation agent, Wet Strength Resin and sizing agent adopt conventional flocculation agent, Wet Strength Resin and sizing agent respectively.
Secondly, according to as shown in Figure 1, in a mixing tank 3, will join successively and carry out premix in the mixing tank 3 earlier according to 20% of suitable water, perlite, sizing agent and above-mentioned granulated wool gross weight, make mixed solution in mixing tank 3, produce shearing force during batch mixing, perlite is well dispersed in the mixed solution by shearing force.
The generation of this shearing force can be passed through as Fig. 1, rotation batch mixing mechanism shown in 2 realizes, specifically: this rotation batch mixing mechanism comprises drive-motor 1, belt 2, turning axle 7, mixing tank 3 and agitating vane 4, agitating vane 4 is arranged on the turning axle 3 and passes through turning axle 7 in 3 li rotations of mixing tank jar, turning axle 3 drives belt 2 rotations by drive-motor 1 and rotates, agitating vane 4 tops are provided with shear plate 5, offer some holes 6 of going up lower edge shear plate 5 up/down perforations on the shear plate 5, shear plate 5 is apart from the suitable spacing in mixing tank 3 tops, distribute preferably at 10～25mm, and along shear plate 3 radial radiation shapes.Wherein, agitating vane 4 can be directly tabular, also can be propeller-like.
When drive-motor 1 drove turning axle 7 rotations, agitating vane 4 drove granulated wool slip and the particles of perlite rotation in the mixing tank 3.Offer porosely 6 on the shear plate 5, the slip band particles of perlite and is just passed through from hole 6, and flows along the direction of arrow shown in Fig. 1.In addition, because shear plate 5 has suitable spacing apart from mixing tank 3 tops, so mixed slurry will be subjected to along the shearing force of shear plate 5 circumferential direction, thereby forming between the shear zone between shear plate 5 and mixing tank 3 tops.Make particles of perlite to be distributed to well in the granulated wool slip by shearing force.In addition,,, and constantly from hole 6, flow through, therefore can access mixed effect very fully along spirrillum direction of arrow rotation among Fig. 1 because mixed slurry forms circinate flowing under the drive of agitating vane 4.
Secondly, the mixed solution that obtains by above-mentioned steps is added to according to suitable adding proportion in the granulated wool manufacturing procedure of mineral wool board production process, the production process of feeding intake of mineral wool board is: flocculation agent → starch → paper → Tai-Ace S 150 → Wet Strength Resin → granulated wool.So just can realize particles of perlite is added in the mineral wool.
The particle diameter of the particles of perlite that adopts is preferably less than 2mm, and perlitic type is open cell type preferably, can be blended in the granulated wool more fully like this.
Through in mineral wool board, being evenly distributed with perlitic light mineral wool slab of the present invention after the above-mentioned processing, not only weight has only and does not add perlitic 90%, and at sound absorption coefficient (NRC) 〉=0.55, than common textile plate sound absorbing capabilities improve a lot (General N RC is about 0.4).
At first, take by weighing each material according to perlite 30%, rock mineral wool 30%, flocculation agent 15%, starch 10%, paper 10%, Wet Strength Resin 0.2%, sizing agent 0.2%, Tai-Ace S 150 4.6%, wherein, each percentages of ingredients is weight percentage.
Concrete preparation process is with embodiment 1, and the light mineral wool slab weight of acquisition only has does not add 70% of perlitic mineral wool board, and at sound absorption coefficient (NRC) 〉=0.55, than common textile plate sound absorbing capabilities improve a lot (General N RC is about 0.4).
Embodiment 3
At first, take by weighing each material according to perlite 15%, rock mineral wool 45%, flocculation agent 10%, starch 7%, paper 15%, Wet Strength Resin 0.5%, sizing agent 0.5%, Tai-Ace S 150 7%, wherein, each percentages of ingredients is weight percentage.
Concrete preparation process is with embodiment 1, and the light mineral wool slab weight of acquisition only has does not add 25% of perlitic mineral wool board, and at sound absorption coefficient (NRC) 〉=0.55, than common textile plate sound absorbing capabilities improve a lot (General N RC is about 0.4).
