Abstract
The invention relates to a method for producing a mineral wool board. the method mainly comprises the following steps that mineral waste materials generated by a mine field are collected; the mineral waste materials are fed into a cupola furnace, coke is added into the mineral waste materials, and the mineral waste materials are fused so that a fused mineral material can be obtained; the liquid fused mineral material is fed into a centrifugal machine and fibrosis cotton-shaped mineral fiber wool can be obtained through centrifugal separation conducted by the centrifugal machine; glue is sprayed to the prepared mineral fiber wool so that a board blank of the mineral wool board can be formed; the mineral wool board is pressurized, hardened and dried; the dried mineral wool board is cut and edge and shape machining is conducted; the surface of the mineral wool board is coated so that a decorative effect can be achieved; the prepared mineral wool board is dried again, and therefore the finished mineral wool board can be obtained. The mineral wool board produced according to the method has the good sound absorption, fireproof and damp-resistant functions and can be suitable for various fields of building 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 mineral fibres cotton as raw material, has decoration, sound-absorbing, insulation, heat insulation, fire prevention, the several functions such as slim and graceful, and maximum feature is to have good sound absorption, effect of heat insulation.Mineral wool is the floccule that slag is thrown away by supercentrifuge through high temperature melting, 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, first make mineral fibres cotton, then in mineral fibres cotton, add water, organic adhesive glue (such as formaldehyde phenol, phenolic resins or polyvinyl alcohol etc.) and unclassified stores, through dehydration, dry, cutting aftershaping.The defect of wet moulding mineral wool board is because need to manufacture slip and dry, so operation and equipment needed thereby are comparatively complicated, and the density of this plate is higher and sound absorbing capabilities is bad.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of utilizing " dry method " slag wool production plate, is in particular the method for the slag wool production plate that a kind of production process is simple and equipment needed thereby is less.
According to the production method of mineral wool board of the present invention, mainly comprise the following steps:
1) collect the mineral waste that mining site produces;
2) mineral waste sent in furnace cupola and add coke to melt, obtaining melting mineral aggregate;
3) liquid molten mineral aggregate is sent in centrifuge, obtained Fibrotic cotton-shaped mineral fibres cotton by the centrifugation of centrifuge;
4) to glue spraying in the mineral fibres cotton making, to form the slab of mineral wool board;
5) pressurize, harden and dry mineral wool board;
6) mineral wool board after drying is cut and the processing of limit shape;
7) surface of mineral wool board is sprayed, to realize decorative effect;
8) mineral wool board making is dried again, can obtain final mineral wool board finished product.
Preferably, step 8) in bake out temperature be 200-300 ℃.
Preferably, step 4) in glue be inorganic glue, its weight proportion is 1-8%.The composition of inorganic glue can be clay, now step 5) in bake out temperature be 120 ℃-150 ℃; The composition of inorganic glue can also be gypsum, now step 5) in bake out temperature be 180 ℃-200 ℃.
Preferably, in step 5) and 6) between also comprise step 5 '): after mineral wool board is dried, utilize binding agent to carry out pad pasting to its surface, binding agent is wherein organic binder bond; Before pad pasting, can also preheat organic binder bond, pre-warmed temperature is 80 ℃, and the coating weight of organic binder bond is 20-180g/m2, when pad pasting, adopts the process of heating continuously, carries out pad pasting by hot-rolling at not higher than the temperature of 200 ℃.
The mineral wool board of producing by " dry method " of the present invention, its density is low, hole is many, absorb sound, and noise reduction coefficient can reach more than 0.7, and wherein content of organics is less, can effectively improve the fire protecting performance of mineral wool board.In addition, owing to having adopted heat curing-type inorganic glue in the present invention, thereby can reduce the hygroscopic deformation amount of mineral wool board in the time of application, improve humidity resistance.
Accompanying drawing explanation
Fig. 1 is according to the schematic diagram of method for producing mineral wool board flow process of the present invention.
The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, hereinafter in connection with accompanying drawing, embodiments of the invention are elaborated.It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can be combined mutually.
According to method for producing mineral wool board of the present invention, mainly comprise the following steps:
1) collect the mineral waste that mining site produces;
2) mineral waste of required weight sent in furnace cupola and add coke to melt, obtaining melting mineral aggregate;
3) liquid molten mineral aggregate is sent in centrifuge, obtained Fibrotic cotton-shaped mineral fibres cotton by the centrifugation of centrifuge;
4) Fibrotic cotton-shaped mineral fibres cotton is sent into glue spraying region and carry out glue spraying, to form the slab of mineral wool board, glue is wherein preferably inorganic glue, for example clay or gypsum, and its weight proportion is 1-8%;
5) pressurize, harden and dry mineral wool board, if wherein inorganic glue is selected clay, preferred bake out temperature is for not higher than 150 ℃, more preferably 120 ℃-150 ℃, if inorganic glue is selected gypsum, preferably bake out temperature for not higher than 200 ℃, more preferably 180 ℃-200 ℃;
6) as required, mineral wool board after drying is cut and the processing of limit shape, this is because mineral wool board needs to splice between piece and piece use when actual use, when splicing, need to utilize connector that adjacent mineral wool board is linked together, this just needs mineral wool board to carry out required limit shape processing, so that install;
7) color and color as required, sprays the surface of mineral wool board, to realize decorative effect;
8) mineral wool board making is dried again, can obtain final mineral wool board finished product, bake out temperature is preferably 200-300 ℃.
As required, sometimes also need to be at the film on surface of mineral wool board, such as PVC film etc.Now, can be in above-mentioned steps 5) and 6) between add step 5 about pad pasting '),, after mineral wool board is dried, utilize binding agent to carry out pad pasting to its surface, binding agent is wherein preferably organic binder bond, such as acrylic acid etc.Before pad pasting, need to preheat organic binder bond, wherein pre-warmed temperature is preferably 80 ℃, and the coating weight of organic binder bond is preferably 20-180g/m
2.Preferably, when pad pasting, adopt the process of heating continuously, at not higher than the temperature of 200 ℃, carry out pad pasting by hot-rolling.
The mineral wool board making in accordance with the present production process, has good sound absorption, fire prevention and moisture-proof function, can be applicable to better the every field of building materials and ornaments.
Although the disclosed embodiment of the present invention as above, the embodiment that described content just adopts for the ease of understanding the present invention, not in order to limit the present invention.Technical staff in any the technical field of the invention; do not departing under the prerequisite of the disclosed spirit and scope of the present invention; can do any modification and variation what implement in form and in details; but scope of patent protection of the present invention, still must be as the criterion with the scope that appending claims was defined.
