Abstract
The invention discloses porous ceramic using waste ceramic as a raw material. The porous ceramic comprises a binder and waste ceramic, wherein the binder is magnesium oxychloride cement, and comprises the following components: magnesium oxychloride, magnesium chloride and a modifier; the weight ratio of the binder to the waste ceramic is 1:6. The waste ceramic is utilized as a filler; the magnesium oxychloride cement is taken as a cementing material; the porous ceramic with certain strength and stability can be formed without high-temperature firing; the porous ceramic not only has the advantages of low raw material price, simple and feasible production process, and low energy consumption, but also well utilizes local resources to change the waste ceramic into treasures; not only can the target of saving energy and reducing emission of buildings be solved, but also the environment pollution caused by the waste ceramic is reduced; the principle of sustainable development is accorded.
Description
Technical field
The present invention relates to a kind of material of construction, be specifically related to a kind of porous ceramics.
Background technology
At present, porous ceramics is to be generally major ingredient by high quality raw material such as emergy, silicon carbide, trichroites, be equipped with the component such as binding agent and pore former and burn till through high temperature, in production, exist that process complexity and processing condition are wayward, efficiency is low, cost is high, the problem such as starting material and article shape is restricted, process energy consumption large, heavy contamination.In addition, in Ceramic Production, use procedure, can be accompanied by and produce a large amount of discarded pottery or unacceptable products, thereby can cause serious environmental pollution and the wasting of resources.
If can recycle discarded ceramic making porous ceramics, can either reach the object of simplifying technique, reducing costs and can reach energy-saving and emission-reduction, protection of the environment.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of porous ceramics, it adopts following technical scheme to realize:
A kind of porous ceramics, is characterized in that, comprise binding agent and waste ceramic, described binding agent is magnesia cement, and described waste ceramic is particulate state, 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, wooden calcium 1-2.
Described magnesium chloride solution degree Beaume is 26-28 degree/20 DEG C.
Described waste ceramic is factory's electroceramics waste product, and waste ceramic grain diameter is 5-10mm, waste ceramic particle silt content≤0.5%, waste ceramic particle crush values≤10%.
beneficial effect:compared with prior art, the invention has the advantages that: the present invention utilizes discarded pottery as filler, taking magnesia cement as consolidating material, do not need can form the porous ceramics with some strength, stability through high-temperature firing, not only there are the prices of raw and semifnished materials cheap, production technique is simple, the advantage that energy consumption is low, and well utilize local resources, discarded pottery is turned waste into wealth, can not only solve the target that building energy-saving reduces discharging, also reduce the pollution of waste ceramic to environment, meet continuable development principle.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail.
