Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of preparation method of the composite light ceramic ecological building materials with humidity conditioning function.
Background technology
Relative air humidity is an important parameter weighing indoor environment comfort level, preserves all significant for HUMAN HEALTH, Air quality and object.Conventional damping means comprise humidifier or humidity adjusting material at present.And humidity adjusting material is mainly divided into several classes below: a class is to utilize separately the natural porous material such as diatomite, zeolite, sepiolite, gypsum as humidity adjusting material; One class is high score subclass water-absorbing resin; One class is salt humidity adjusting material.Wherein, humidifying apparatus need to consume a large amount of electric energy; Can make this mineral wealth consume the defects such as excessive and slow, the saturated wet volume capacity of moisture adsorption and releasing response speed is low and utilize separately certain raw mineral materials to prepare humidity adjusting material; Excessively strong for its water-retentivity of polymer humidity adjusting material, cause moisture releasing susceptibility low; The easy aquation of inorganic salts humidity adjusting material moisture absorption, pollutes.These have all affected damping effect and the use properties of material.
Having publication number is that CN101205135A Chinese patent relates to a kind of functional form inner-wall brick, is mainly made up of natural non-metallic minerals opal light rock, burns till through 1100 DEG C～1250 DEG C, has nature humidity conditioning function; Publication No. is that CN103172401A Chinese patent relates to one and has humidity conditioning function pottery wall tile and preparation method thereof, and firing temperature is 1160 DEG C～1180 DEG C, and moisture uptake is greater than 70g/m
2, moisture releasing amount is 30～45g/m
2, publication No. is that CN102515726A Chinese patent relates to a kind of internal wall brick with adsorption function and preparation method thereof, this patent is mainly made up of internal wall brick basestocks and silicate material, forms by a firing.Publication No. is the preparation method that CN102304348A Chinese patent relates to a kind of humidity adjusting material, and main raw material is that aluminum oxide, diatomite powder, sodium-chlor, salt of wormwood, organism etc. are prepared humidity adjusting material.From above-mentioned patent, humidity conditioning function internal wall brick will burn till through high temperature at present, or prepares powder humidity adjusting material.But high temperature burns till and can destroy the microvoid structure in raw material, reduces rate of moisture absorption and Saturated Moisture Content.For powder humidity adjusting material, although can increase its moisture absorption susceptibility after inorganic salt modification, because powder structure is unstable, the inorganic salt after moisture absorption aquation are difficult for being detained in powder structure, can cause secondary pollution.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of composite light ceramic ecological building materials with humidity conditioning function, the method simple process, firing temperature is low, and moisture absorption and desorption property is good, and comprehensive utilization of resources rate is high, energy-conserving and environment-protective.
A preparation method with the composite light ceramic ecological building materials of humidity conditioning function, comprises the following steps:
(1) following raw material is mixed: by percentage to the quality, diatomite 10%～50%, clay 10%～30%, potassium sodium sand 10%～25%, quartz sand 5%～35%, talcum sand 1%～10%, water-soluble pore-forming material 1%～5%, Wingdale 14%～25%;
(2) add the water of above-mentioned raw materials gross weight 35%～60%, 0.01～0.5% dispersion agent, 0.01～0.5% base substrate toughener, carry out ball milling, slurry iron-removing after ball milling sieves, add 5%～25% solid pore-forming material in granulation, powder after granulation, high velocity air impulse machine mixes, old 10～24 hours, compression moulding, dry, then burn till soaking time 10min～40min at 800 DEG C～950 DEG C;
(3) by 1%～5%CaCl
2be compounded in the top layer of the product after burning till, make the damping light building material that contains multi-stage porous gauge structure.
Described clay class be in Yonghe County's mud, middle mountain mud, mud washing and Zhuhai mud one or more, with four kinds the best that is mixed into.
Described water-soluble pore-forming material is polyacrylamide or sodium polyacrylate; Described solid pore-forming material is one or more in wood chip, starch, carbon dust, cinder and Wingdale.
Described solid pore-forming material sieves more than 100 orders.
The pressure of described moulding is 5MPa～20MPa.
Described dispersion agent is tripoly phosphate sodium STPP, water glass, Sodium hexametaphosphate 99 or Sodium salts humic acids.
Described base substrate toughener is wooden sodium sulfonate, polyvinyl alcohol or CMC.
First, the natural mineral that the present invention exists in a large number taking natures such as diatomite, Yonghe County's mud, middle mountain mud, mud washing, Zhuhai mud, potassium sodium sand, quartz sand, talcum sand, Wingdales, as raw material, is guaranteed the stability of formula and the sustainability of production.Secondly, the addition manner of pore-forming material is wet mixing and be dry mixed the mode combining.Wet mixing shows: water-soluble pore-forming material is blended in other raw material to ball milling together, and the mud mist projection granulating after ball milling, in granulation process, water-soluble pore-forming material dewaters rapidly, and pore-forming material is wrapped in powder granule inside uniformly; Be dry mixed and show: after mist projection granulating, the solid pore-forming material such as gained powder and starch, wood chip, carbon dust, cinder again carries out machinery and is dry mixed, and mixed powder burns till through compression moulding, makes interiors of products have hierarchical porous structure.Wherein macropore is mainly piled up institute after solid pore-forming material and compression moulding and is produced by being dry mixed between particle, micropore is mainly that the water-soluble pore-forming material being wrapped in particle during by diatomite and wet mixing is produced, this hierarchical porous structure has given product large saturated wet volume capacity, also makes the proportion of product be minimized.
With the mode complex inorganic salt catalyst CaCl of spraying
2, the CaCl after compound
2be dispersed in uniformly product billet surface, thereby improve the moisture absorption susceptibility of material.In addition, make this interiors of products have hierarchical porous structure by adding pore-forming material, this structure not only can homodisperse carrying CaCl
2particle, and can be by CaCl
2the water vapour that moisture absorption is come is shifted, and prevents its aquation, thereby has greatly improved the saturated wet volume capacity of product.Finally, in formula, the introducing of Wingdale not only can reduce firing temperature, and has reduced the destruction to microvoid structure in sintering process, has ensured its higher suction, moisture releasing response speed and saturated wet volume capacity.Finally make that this product has that wet volume capacity is high, suction, moisture releasing susceptibility is good, proportion is low, lightweight, the features such as energy-conserving and environment-protective.
The present invention compared with prior art, the invention has the beneficial effects as follows:
Compare 1150 DEG C～1250 DEG C firing temperatures of general ceramic tile, firing temperature of the present invention is 800 DEG C～950 DEG C, easy fired is not only energy-conservation, and reduce the destruction to microvoid structure in raw material, guarantee that product has hierarchical porous structure, thereby make fast, the saturated wet volume capacity of product moisture adsorption and releasing response large, can reach 2000g/m
2, indoor environment humidity can be maintained to 40%～70% this comfort humidity scope.In addition, because this product is through firing process, compare similar humidity adjusting material, its intensity is high, is greater than 9MPa, long service life.Finally, in the present invention's formula, low grade material utilization ratio is high, can reach 50%～90%, greatly reduces the use of the precious resources such as diatomite, has reduced production cost.
