Description
Technical Field
The invention relates to the technical field of refractory plastic materials, in particular to an impact-resistant, acid-erosion-resistant and refractory plastic material for an incinerator lining and a preparation method thereof.
Background
The incinerator is an environment-friendly device which can incinerate waste gas, waste liquid, solid waste fuel, medical waste, household waste, animal carcasses and the like at high temperature to reduce or reduce the quantitative number, and simultaneously achieves a product which utilizes the heat energy of partial incineration media, so that the incinerator meets the requirements of the inner lining of the incinerator for adapting to the rapid development of the environment-friendly industry, the waste to be treated and incinerated is generally a heterogeneous mixture with different compositions, the types, the contents and the heat values of the waste are greatly different, a plurality of waste incinerator inner linings use various high-quality refractory materials and obtain good use effect, and the refractory materials refer to inorganic nonmetallic materials with the refractoriness of not lower than 1580 ℃. The lining of the incinerator needs to meet the requirements of the kiln during operation. However, at present, the erosion of gas in the materials entering the furnace and the abrasion and impact of the materials on the furnace lining in the high-temperature process are main causes of the damage of the lining body; and the amount of refractory material which can prolong the life of the high-temperature lining of the waste incinerator is very small, so that it is urgent to continuously research and improve the refractory material for the lining of the waste incinerator with excellent performance.
Disclosure of Invention
Aiming at the problems, the invention provides an impact-resistant, acid-erosion-resistant and fire-resistant plastic material for an incinerator lining and a preparation method thereof, wherein the impact-resistant, acid-erosion-resistant and fire-resistant plastic material has the characteristics of stable high-temperature volume stability, excellent high-temperature toughness and wear resistance, excellent acid resistance, good thermal shock stability, good heat resistance and heat insulation and the like, the maximum use temperature of the plastic material is 1500 ℃, and the plastic material can be used as a lining body of a garbage incinerator.
