Abstract
The invention discloses a kind of porous ceramics using waste ceramic to be raw material, including binding agent and waste ceramic.Described binding agent is magnesia cement, and its component includes magnesium oxychloride, magnesium chloride and modifying agent, and described binding agent and waste ceramic weight ratio are 1:6.The present invention utilizes discarded pottery as filler, with magnesia cement as cementing material, needing not move through high-temperature firing and can form the porous ceramics with some strength, stability, not only have the prices of raw materials cheap, production technology is simple, the advantage that energy consumption is low, and well utilize local resources, discarded pottery is turned waste into wealth, the target that building energy-saving reduces discharging can not only be solved, also reduce the waste ceramic pollution to environment, meet continuable development principle.
Description
Technical field
The present invention relates to a kind of construction material, be specifically related to a kind of porous ceramics.
Background technology
At present, it is major ingredient that porous ceramics is usually by quality raw materials such as emergy, carborundum, cordierites, is equipped with binding agent
Burning till through high temperature with the component such as pore former, the process that also exists in production is complicated and process conditions are wayward, efficiency is low, cost
The problems such as height, raw material and article shape is restricted, process energy consumption big, heavy contamination.It addition, in Ceramic Production, use
During along with producing a large amount of discarded potteries or defective work, thus can cause serious environmental pollution and resource wave
Take.
If discarded ceramic making porous ceramics can be recycled, Simplified flowsheet can either be reached, reduce cost and again can
Reach energy-saving and emission-reduction, the purpose of protection environment.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of porous ceramics, it adopts the following technical scheme that reality
Existing:
A kind of porous ceramics, it is characterised in that include that binding agent and waste ceramic, described binding agent are magnesia cement, institute
Stating waste ceramic is graininess, and described binding agent and waste ceramic weight ratio are 1:6.
Described magnesia cement is made up of following parts by weight component: magnesium oxychloride 80-90, magnesium chloride solution 45-55, phosphoric acid 2-
3, wood calcium 1-2.
Described magnesium chloride solution Baume degrees is 26-28 degree/20 DEG C.
Described waste ceramic is factory's electroceramics waste product, and waste ceramic grain diameter is 5-10mm, and waste ceramic granule contains mud
Amount≤0.5%, waste ceramic Particle Crush value≤10%.Beneficial effect: compared with prior art, it is an advantage of the current invention that: this
The pottery that invention utilization is discarded is as filler, with magnesia cement as cementing material, it is not necessary to can form tool through high-temperature firing
Having the porous ceramics of some strength, stability, not only have the prices of raw materials cheap, production technology is simple, and energy consumption is low
Advantage, and well utilize local resources, discarded pottery is turned waste into wealth, the mesh that building energy-saving reduces discharging can not only be solved
Mark, also reduces the waste ceramic pollution to environment, meets continuable development principle.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.
Embodiment one:
It is magnesium oxychloride 80 parts by parts by weight, magnesium chloride solution 45 parts, phosphoric acid 2 parts, wood calcium 1 part mixing, chlorination when 20 DEG C
Magnesium solution Baume degrees is 26 degree, stirs and makes binding agent；Graininess, grain diameter will be ground into from factory's electroceramics waste product
For 5mm, control porcelain granule clay content≤0.5%, Particle Crush value≤10%；Just binding agent is with waste ceramic granule by weight
For 1:6 mixing, stirring, pour in mould, vibration removes bubble, after 6h solidifies, takes out from mould, has both obtained required many
Hole pottery.
Embodiment two:
Substantially the same manner as Example 1, except that, magnesium oxychloride 85 parts, magnesium chloride solution 50 parts, phosphoric acid 2.5 parts, wood calcium
1.5 parts, when 20 DEG C, magnesium chloride solution Baume degrees is 27 degree, and waste ceramic grain diameter is 8mm.
Embodiment three:
Substantially the same manner as Example 1, except that, magnesium oxychloride 90 parts, magnesium chloride solution 55 parts, phosphoric acid 3 parts, wood calcium 2
Part, when 20 DEG C, magnesium chloride solution Baume degrees is 28 degree, and waste ceramic grain diameter is 10mm.
Detection data are shown in Table 1.
Table 1 detects data
