Abstract
The invention relates to a production method of mineral wool boards, which mainly comprises the following steps: adding foaming agent to a binder; dosing: mixing the foaming agent, the binder, mineral fiber cotton, a flocculating agent and a desiccant; stirring the ingredients evenly, and enabling mineral wool boards to be formed in a coarse manner; adopting the wet process fourdrinier wire beater-addition process to eliminate moisture in the coarse-formed mineral wool boards; putting the coarse-formed mineral wool boards in a hot and humid environment for drying and evaporation; performing primary coarse cutting and planing the surfaces of the coarse-formed mineral wool boards; performing primary spraying on the surfaces and drying the coarse-formed mineral wool boards; performing knurling on the surfaces of the coarse-formed mineral wool boards; performing secondary refined cutting, and tenoning on the periphery; performing secondary spraying on the surfaces and drying, so that the finished products of the mineral wool boards are acquired. The mineral wool boards produced with the method disclosed by the invention possess excellent sound absorption and dampproof functions, more cavities and low density, save cost, and can be better applicable to various fields of building materials decoration.
Description
Technical field
The present invention relates to a kind of production method of mineral wool board.
Background technology
Mineral wool board is the novel environment friendly building materials of making take the mineral fibers cotton as raw material, has decoration, sound-absorbing, insulation, heat insulation, fire prevention, the several functions such as slim and graceful, and maximum characteristics are to have good sound absorption, effect of heat insulation.Mineral wool then is the floccule that slag is thrown away by supercentrifuge through high temperature melting, and is harmless, pollution-free, be a kind ofly turn waste into wealth, the green building material of favorable environment.Therefore, mineral wool board has very strong applicability at building field.
The method of traditional mode of production mineral wool board is wet production, namely at first make the mineral fibers cotton, then in the mineral fibers cotton, add water, organic adhesive glue (such as formaldehyde phenol, phenolic resins or polyvinyl alcohol etc.) and unclassified stores, through dehydration, oven dry, cutting aftershaping.The defective of wet moulding mineral wool board is that the density of this plate is higher and sound absorbing capabilities is bad.And, for the mineral wool board of producing by conventional wet, owing to needing effects on surface to planish, if the finished product of needs is that 15mm is thick like this, then needs at least 16.5mm during moulding, thereby increased the consumption of material.
Summary of the invention
The object of the present invention is to provide a kind of production method of mineral wool board, it can reduce the consumption of material, and the sheet material sound absorbing capabilities that forms is better.
Production method according to mineral wool board of the present invention mainly may further comprise the steps:
1) blowing agent is added in the cementing agent;
2) batching: blowing agent, cementing agent and mineral fibers cotton, flocculant, anti-blushing agent are mixed;
3) batching is stirred and thick moulding mineral wool board;
4) adopt the wet method fourdrinier wire to copy taking technique and remove moisture in the thick moulding mineral wool board;
5) thick moulding mineral wool board is in and carries out the drying evaporation in the hot and humid environment;
6) for the first time rough lumber is cut and is planished in its surface;
7) sprayed surface and with its oven dry for the first time;
8) embossing on the crude product mineral wool board surface that obtains;
9) carry out the essence cutting second time, and at its peripheral mortise;
10) sprayed surface and with its oven dry for the second time, thus the finished product of mineral wool board obtained.
Preferably, blowing agent is selected inorganic foaming agent.Cementing agent is selected inorganic clay, starch, polyvinyl alcohol or modified starch.Inorganic clay is selected attapulgite.Inorganic foaming agent can be borax, sodium carbonate, sodium phosphate or sodium acid carbonate.
Preferably, wherein the content of blowing agent accounts for the 1-5% of gross weight, and the content of cementing agent is 5-10%, and the content of mineral fibers cotton is more than 80%, and content of flocculating is 0.5-1%, and the content of anti-blushing agent is 1%.Foaming is adopted and is lower than 125 ℃ low-temp foaming.More preferably, the content of mineral fibers cotton is 83%, and flocculant is aluminum sulfate.
Preferably, step 5) high temperature in is 180 ℃-260 ℃ temperature, and high humidity is the humidity of 75-95%.More preferably, step 5) high temperature in is 180 ℃-220 ℃ temperature, and high humidity is the humidity of 80-90%.
The mineral wool board density of producing by the method is low, cavity is many, absorb sound, noise reduction coefficient can reach more than 0.6, and because the use of organic additional adhesive, make it have preferably film forming and caking property, and can effectively resist the Wicking phenomenon that occurs in the use procedure and the distortion of sheet material.In addition, if the finished product that needs is that 15mm is thick, then only need 9mm during moulding, greatly reduced the consumption of material.
Description of drawings
Fig. 1 is the schematic flow sheet according to method for producing mineral wool board of the present invention.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, hereinafter in connection with accompanying drawing embodiments of the invention are elaborated.Need to prove, in the situation that do not conflict, the embodiment among the application and the feature among the embodiment be any combination mutually.
According to method for producing mineral wool board of the present invention, mainly may further comprise the steps:
1) blowing agent is added in the cementing agent.Preferably, blowing agent is selected inorganic foaming agent, such as borax, sodium carbonate, sodium phosphate or sodium acid carbonate etc.; Cementing agent can be selected inorganic clay, starch, polyvinyl alcohol or modified starch, and to improve viscosity, inorganic clay wherein is preferably attapulgite.
2) batching: blowing agent, cementing agent and mineral fibers cotton, flocculant, anti-blushing agent are mixed.Wherein the content of blowing agent accounts for the 1-5% of gross weight; The content of cementing agent is 5-10%; The content of mineral fibers cotton is more than 80%, to be preferably 83%; Flocculant is preferably aluminum sulfate, and content is 0.5-1%, and the content of anti-blushing agent is 1%.The gas that foaming produces is the carbon dioxide of nonhazardous, the general low-temp foaming that adopts of foaming, and namely blowing temperature is lower than 125 ℃, like this can be so that gas release is large.
