Description
1. technical field
The present invention relates to a kind of diatomite-based multifunctional micropore ceramic preparation methods, belong to the Materials Science and Engineering field.
2. background technology
Porous ceramics is a kind of containing than multiple hole, and is a class ceramic that utilizes function that its pore space structure has.Because of characteristic such as it has that thermal conductivity is low, perviousness is high, high-temperature stability and chemical stability are good, in aspect extensive application such as catalysis, separation, lightweight structural material, biomaterials and receive much concern.At present, commercial porous ceramics mainly is with Al
2O
3, SiC, ZrO
2With mullite be the porous ceramics of main raw material preparation, though intensity is better, aperture broad, bigger, and high firing temperature has limited porous ceramics promotion and application in many aspects in the high price of these materials and the preparation process.Therefore, seek proper raw material, reduce sintering temperature and production cost, positive effect is arranged for the widespread use of porous ceramics.
Diatomite is that the remains of the diatoms that grows in ocean or the lake are at subaqueous deposit, a kind of nonmetallic minerals that passes through geologic function and form gradually, the diatom shell structure of its uniqueness, strong adsorptivity, bigger serface, highly porous, advantageous property such as high temperature resistant, in modern industry, be used for chemical industry and environmental protection field in a large number.In recent years, diatomite has the micropore below a large amount of micron orders and is subjected to people's attention with its wide material sources, cheap, inside.Utilize the characteristics of original hole in the diatomite, adopt to add additive and cryogenic calcining process remains original duct and particles of aggregates is piled up the space, can make economically the aperture tiny, be evenly distributed, porous ceramics with low cost.This material not only can be applicable to the various ultraprecises and the sterile filtration of aspects such as beverage, sewage disposal, petrochemical complex, and this porous material also can be used as carrier (as loaded with nano TiO
2).
Tourmalinite is a kind of by Al, Na, Ca, Mg, the ring silicate mineral of the moisture and fluorine that B and Fe etc. are elementary composition etc.Find that from Nakamura in 1989 and Kubo there is the electrostatic field phenomenon in tourmalinite around having spontaneous electrode, particulate, the electrical effect of tourmalinite has been launched a series of research at this point, risen the research boom of tourmalinite thus in environment, body-care field.After this, state scholars such as Japan, the U.S. have begun the research of this respect one after another, have applied for multinomial patent successively.But in many Application Areass, tourmalinite often all is to occur with powder morphology.Yet,, and be difficult to reclaim and reuse because the strong polarity and the particulate granular of superfine tourmaline powder itself are used inconvenience under many circumstances.
The objective of the invention is at the deficiency in the present porous ceramic film material preparation, with diatomite is base-material, the an amount of ultra-fine tourmaline powder that adds, by control to technology, the preparation specific surface area is big, the aperture is tiny, light weight, absorption property are good, and organic pollutant is had the diatomite-based multifunctional new ceramic material of certain degradation capability.This material has fine environment Pollution abatement function, can be used as atmospheric pollution and water pollution control and solid support material.And preparation cost is low, use and reclaim conveniently, and use is environmentally friendly.
3. summary of the invention
Content of the present invention is with diatomite, tourmalinite and sintering aid, mix with water, dispersion agent, binding agent the batching back by a certain percentage, add in the grinding machine that grinding medium is housed and grind, to certain fineness after-filtration, drying, through moulding and calcining, produce diatomite-based multifunctional micropore ceramic (Fig. 1) then.
Its processing step is as follows:
(1) with diatomite, tourmalinite, sintering aid is prepared burden by a certain percentage;
(2) at the diatomite for preparing, tourmalinite adds dispersion agent in the sintering aid compound, behind binding agent and the water, feeds ground and mixed in the shredder;
(3) with ground compound filtration, drying;
(4) with dried compound moulding, calcining.
Below be prescription of the present invention and main technique condition:
(1) batching
1. diatomite, tourmalinite, the ratio of components of sintering aid is a diatomite: tourmalinite: sintering aid=70～90: 5～25: 1～10;
2. the granularity of tourmalinite raw material is D
50=0.2～5 μ m.
(2) diatomite, tourmalinite, the ground and mixed of sintering aid admixtion
1. the proportioning of admixtion and dispersion agent, binding agent and water is: compound: dispersion agent: binding agent: water=100: 0.1～2: 0.5～5: 100～250.
2. grinding the disposed slurry size-grade distribution is D
97≤ 10 μ m.
(3) moulding and calcining
Forming pressure 30～80MPa; 850～1050 ℃ of calcining temperatures, soaking time 1～5h.
With the multi-functional micropore ceramics of the present invention's preparation, the aperture is tiny, even, porosity is high.The aperture mainly concentrates on 20nm and 200nm, about mean pore size 50nm, and specific surface area＞13m
2/ g, porosity 〉=37% (Fig. 2～4).
Advantage of the present invention: the one, the diatomite source is wide, and the material produce cost is low; The 2nd, diatomaceous main chemical compositions is an amorphous silica, and sintering temperature is low, and is energy-conservation; The 3rd, in batching, add the ultra-fine tourmaline powder, make the natural electric polarity of tourmalinite, far-infrared radiation, discharge performance such as negative ion and diatomaceous porous (the natural nano hole of regular distribution), light weight, sound insulation, heat insulation combination, make porous ceramics have multiple function, the treating indoor air pollution in environmental protection field and fresh air, water pollution control, sound insulation and energy-conservation aspect good prospects for application is arranged.
