Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of preparation method with the composite light ceramic ecological building materials of humidity conditioning function.
Background technology
Relative air humidity is the important parameter weighing indoor environment comfort level, preserves all significant for HUMAN HEALTH, Air quality and object.Damping means conventional at present comprise humidifier or humidity adjusting material.And humidity adjusting material is mainly divided into a few class below: a class utilizes 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 needs to consume a large amount of electric energy; And utilize separately certain raw mineral materials to prepare humidity adjusting material these mineral wealth can be made to consume the defects such as excessive and slow, the saturated wet volume capacity of moisture adsorption and releasing response speed is low; 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 all have impact on damping effect and the use properties of material.
There is publication number to be that CN101205135A Chinese patent relates to a kind of functional form inner-wall brick, make primarily of natural non-metallic mineral opal light rock, burn till through 1100 DEG C ~ 1250 DEG C, there is nature humidity conditioning function; Publication No. is that CN103172401A Chinese patent relates to one and has humidity conditioning function Ceramic 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, and this patent, primarily of internal wall brick basestocks and silicate material composition, 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 aluminum oxide, diatomite powder, sodium-chlor, salt of wormwood, organism etc. prepare humidity adjusting material.From above-mentioned patent, current humidity conditioning function internal wall brick will burn till through high temperature, or prepares powder humidity adjusting material.But high temperature burns till the microvoid structure that can destroy in raw material, reduce 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 not easily 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 resource utilization rate is high, energy-conserving and environment-protective.
There is a preparation method for the composite light ceramic ecological building materials of humidity conditioning function, comprise 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) water of above-mentioned raw materials gross weight 35% ~ 60% is added, 0.01 ~ 0.5% dispersion agent, 0.01 ~ 0.5% base substrate toughener, carry out ball milling, slurry iron-removing after ball milling sieves, granulation, add 5% ~ 25% solid pore forming agent in powder after the pelletizing, high velocity air impulse machine mixes, old 10 ~ 24 hours, compression moulding, drying, then to burn till at 800 DEG C ~ 950 DEG C, soaking time 10min ~ 40min;
(3) by 1% ~ 5%CaCl
2be compounded in the top layer of the product after burning till, i.e. the obtained damping light building material containing multilevel pore size structure.
Described clay class be in Yonghe County's mud, middle mountain mud, mud washing and Zhuhai mud one or more, with four kinds be mixed into the best.
Described water-soluble pore-forming material is polyacrylamide or sodium polyacrylate; Described solid pore forming agent is one or more in wood chip, starch, carbon dust, cinder and Wingdale.
Described solid pore forming agent sieves more than 100 orders.
Described shaping pressure 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 with natures such as diatomite, Yonghe County's mud, middle mountain mud, mud washing, Zhuhai mud, potassium sodium sand, quartz sand, talcum sand, Wingdales, for raw material, guarantees the sustainability of stability and the production of filling a prescription.Secondly, the addition manner of pore-forming material is wet mixing and be dry mixed the mode combined.Wet mixing shows: water-soluble pore-forming material to be mixed in other raw material ball milling together, the mud mist projection granulating after ball milling, in granulation process, water-soluble pore-forming material rapid dehydration, makes pore-forming material be wrapped in powder granule inside uniformly; Be dry mixed and show: after mist projection granulating, the solid pore forming agent 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 there is hierarchical porous structure.Wherein macropore produced primarily of piling up between particle after being dry mixed solid pore forming agent and compression moulding, micropore mainly produced by the water-soluble pore-forming material be wrapped in when diatomite and wet mixing in particle, this hierarchical porous structure imparts the large saturated wet volume capacity of product, 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 product billet surface uniformly, thus 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 by CaCl
2the water vapour that moisture absorption is come is shifted, and prevents its aquation, thus substantially increases the saturated wet volume capacity of product.Finally, in formula, the introducing of Wingdale not only can reduce firing temperature, and also reduces the destruction to microvoid structure in sintering process, ensure that its higher suction, moisture releasing response speed and saturated wet volume capacity.Finally make this product have wet volume capacity high, inhale, 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 general ceramic tile 1150 DEG C ~ 1250 DEG C firing temperatures, firing temperature of the present invention is 800 DEG C ~ 950 DEG C, easy fired is not only energy-conservation, and the destruction decreased microvoid structure in raw material, guarantee that product has hierarchical porous structure, thus it is large to make product moisture adsorption and releasing respond fast, saturated wet volume capacity, can reach 2000g/m
2, indoor environment humidity can be maintained 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, the present invention's middle-low grade raw material availability of filling a prescription is high, can reach 50% ~ 90%, greatly reduce the use of the precious resources such as diatomite, reduce production cost.
