Technical field
The invention belongs to Materials Science and Engineering field, prepared by more particularly to a kind of Diatomite-based Porous Ceramics
Method.
Background technology
Diatomite be the remains of the Diatomeae grown in ocean or lake in subaqueous deposit, by geologic process
And a kind of nonmetallic minerals for gradually forming, the diatom shell structure of its uniqueness, strong adsorptivity, compare table greatly
The advantageous properties such as area, high porosity, high temperature resistant, in modern industry, are largely used to chemical industry and ring
Guarantor field.In recent years, diatomite with its wide material sources, it is cheap, internal with a large amount of micron orders with
Under micropore and paid close attention to by people.Using the characteristics of original hole, Bian is added with addition in diatomite
Agent and cryogenic calcining process make original duct remain and particles of aggregates accumulation space, can be economically
It is obtained that aperture is tiny, be evenly distributed, porous ceramics with low cost.The material may be applied not only in beverage,
The various ultraprecises of the aspects such as sewage disposal, petrochemical industry and aseptic filtration, this porous material can also be made
It is carrier.
Porous ceramics is that one kind contains compared with multiple hole, and is have functional one using its pore space structure
Class Inorganic Non-metallic Materials.Have that thermal conductivity is low, permeability is high because of it, high-temperature stability and chemically stable
Property the characteristic such as good, have extensive answering at aspects such as catalysis, separations, lightweight structural material, biomaterials
With and receive much concern.At present, the porous ceramics of commercialization is mainly with Al2O3, SiC, ZrO2Do not come
Stone is porous ceramics prepared by primary raw material, although intensity is preferable, but aperture is wider, larger, and this
Firing temperature high limits porous ceramics pushing away in many aspects in the high price and preparation process of a little materials
Wide and application.Therefore, suitable raw material is found, sintering temperature and production cost is reduced, for porous pottery
The extensive use of porcelain plays the role of positive.
The content of the invention
In overcoming the shortcomings of prepared by existing current porous ceramic film material, the present invention provides a kind of diatom
Soil matrix porous ceramics preparation method.
The purpose of the present invention is reached by following measures：A kind of Diatomite-based Porous Ceramics are provided to prepare
Method, in turn includes the following steps：With diatomite as primary raw material, add according to a certain percentage appropriate
Sintering aid, dispersant, binding agent, add zirconia ball, using superfine wet-type grinding technics, to one
Determine to be filtered after fineness, dry, then through half dry-pressing formed and cryogenic calcining process, prepare diatomite Quito
Hole ceramics.
Further, the composition of the sintering aid is kaolin, quartz, feldspar, and its mass ratio is 3:1:3,
It is 2~3 with diatomaceous mass ratio:17.
Further, the dispersant is sodium metasilicate, and it is 0.1~2 with diatomaceous mass ratio:85.
Further, in the superfine wet-type process of lapping, diatomite and sintering aid batch, dispersion
The proportioning of agent, binding agent and water is：Batch：Dispersant：Binding agent：Water=40~90:0.1~2：0.5
~5：100~250.
Further, in the process of lapping, the diameter of zirconia ball is distributed as 3~5mm, pellet quality
Than 1:4~5, the size distribution for grinding disposed slurry is D98≤10 μm.
Further, the shaping and calcine technology condition are：30~80MPa of briquetting pressure；Calcining temperature
It is 850~1050 DEG C to spend, and soaking time is 2~5h.
Preparation method belonging to of the invention has advantages below：One is that diatomite source is wide, material production cost
It is low；Two is that diatomaceous main chemical compositions are amorphous silica, and sintering temperature is low, energy-conservation；Three
It is the function such as diatomaceous porous (the natural nano hole of regular distribution), light weight, sound insulation, heat-insulated,
Make porous ceramics that there are various functions, in treating indoor air pollution and fresh air, the water of field of Environment Protection
Pollution control, sound insulation and energy-conservation aspect have good application prospect.
Specific embodiment
Below by embodiment, the present invention is described in detail.
With diatomite as primary raw material, appropriate sintering aid, dispersant are added according to a certain percentage, is glued
Knot agent, add zirconia ball, using superfine wet-type grinding technics, to certain fineness after filtering, dry,
Again through half dry-pressing formed and cryogenic calcining process, Diatomite-based Porous Ceramics are prepared.
Further, the composition of the sintering aid is kaolin, quartz, feldspar, and its mass ratio is 3:1:3,
It is 2~3 with diatomaceous mass ratio:17.
Further, the dispersant is sodium metasilicate, and it is 0.1~2 with diatomaceous mass ratio:85.
Further, in the superfine wet-type process of lapping, diatomite and sintering aid batch, dispersion
The proportioning of agent, binding agent and water is：Batch：Dispersant：Binding agent：Water=40~90:0.1~2：0.5
~5：100~250.
Further, in the process of lapping, the diameter of zirconia ball is distributed as 3~5mm, pellet quality
