Abstract
The invention relates to a foamed ceramic material and a preparation method thereof. The foamed ceramic material comprises the following components in percentage by mass: 45-70% of lead-zinc tailing, 28-52% of polished tile waste slag and 0.5-3% of foaming agent, wherein the foaming agent is silicon carbide preferably. The preparation method comprises the following steps: proportioning according to the formula, and grinding; performing spray drying on the materials; and putting in a kiln, heating at a rate of 5-10 DEG C/min, firing at 1130-1230 DEG C, keeping the temperature for 30-80 minutes, discharging from the kiln, and cutting into the required shape. According to the invention, the raw materials are innovative, a large amount of lead-zinc tailing is used, the composition of the raw materials is simple, and the operability is high; the tailing self can be blackened under high-temperature calcination effect, so that no colorant needs to be added; the lead-zinc tailing has the characteristics of high calcium content and high iron content, so that the firing energy consumption of the foamed ceramic can reduced without adding a fluxing agent; and a large amount of lead-zinc tailing is used, thus reducing the pollution of the lead-zinc tailing to the environment.
Description
Technical field
The invention discloses a kind of Pb-Zn tailings that utilizes and be main raw material, for the preparation of a kind of foamed ceramic material of building exterior wall heat preserving and preparation method thereof.The invention belongs to the crossing domain of the mine tailing utilization of resources and building material technology.
Background technology
Building under the tide promotion of green energy conservation society, people improve day by day to expectation and the pursuit of building energy conservation, have adopted various bodies of wall to go along with sb. to guard him system such as bulk external insulation system, bulk folder (filling out) core architecture and sheet material class complex heat-preservation system.But organic insulation material is easy to burning, has safety problem.The inorganic energy-saving heat preserving material of construction of development of new is imperative.
The foamed ceramic material is developed in order to satisfy this demand.The foamed ceramic material has building thermal-insulation energy-saving, does not fire and multiple effect such as sound insulation fully, is the outer wall material of a new generation, will play huge effect for building energy conservation.The foamed ceramic material that the present invention proposes is to be main raw material with the Pb-Zn tailings, not only saved the ceramic resources of high-quality, and having reduced raw materials cost, it has good thermal property and excellent workability and can be used as the energy conservation project that energy saving building material is used for modern building.
Chinese patent CN102718547A discloses a kind of foamed ceramic material and preparation method.It is raw material with high silicon tailings, feldspar, whipping agent, foaming control agent, fusing assistant, and it is milled to more than 250 orders, adopts the way of control temperature-rise period to burn till between 1080～1300 ℃.This formula material complexity, firing temperature height, poor operability.
Chinese patent CN102399090A discloses a kind of preparation method of light vitreous foamed ceramic.Its major technique characteristics are to be raw material with ceramic wall, floor tile grinding wet-milling skeleton material, china clay, talcum, wilkinite, whipping agent and the tremolite, and it is ground to 300～500 orders, burn to the raw material vitrification point.This patent is to be main raw material with the traditional ceramics raw material, and material prescription is various and complicated.
