Foamed ceramic prepared by virtue of oil well earth and waste glass and method for foamed ceramic

Abstract

The invention relates to foamed ceramic prepared by virtue of oil well earth and waste glass and a method for the foamed ceramic, and belongs to the technical field of ceramic materials. The foamed ceramic is prepared from the following raw materials in parts by weight: 15 to 35 parts of oil well earth, 20 to 35 parts of waste glass, 5 to 10 parts of feldspar, 5 to 10 parts of bentonite and 5 to 25 parts of a foaming agent. A preparation process for the foamed ceramic is simple, the firing temperature is low, and the prepared foamed ceramic is strong in strength and low in heat conductivity and specific gravity, and can be used as an excellent heat-preservation, sound-absorption and heat-insulation material. In addition, the foamed ceramic product is suitable to be used for heat preservation and heat insulation of industrial equipment and pipes, is more suitable to be used for heat preservation of building external walls and roofs, indoor heat insulation and the like, and has the characteristics of fire retardancy, waterproofness, no aging, corrosion resistance, zero radioactivity, high dimensional stability and the like, so that problems about environmental protection are solved, and meanwhile, better economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and relates to a foam ceramic, in particular to a foam ceramic prepared by using oil well soil and waste glass and a method thereof. Background technique [0002] Since humans began to use cars as a tool, oil has been continuously extracted, which has caused serious pollution to the soil and soil near oil wells, so that it is difficult to recycle and can only be disposed of by landfill, which has caused great pressure on the environment. At present, the soil near oil wells is mainly improved by biological methods, but compared with the huge production volume, the utilization rate is still very low, causing a great environmental burden. [0003] Foamed ceramics have excellent thermal insulation, sound absorption, fire prevention, waterproof and moisture-proof, acid and alkali resistance, etc., and can be used as thermal insulation, heat insulation and decoration materials in chemical ind...

Problems solved by technology

[0004] The patent with the authorized notification number CN102617180B discloses a porous foam ceramic and its preparation method. The ceramic is mainly made of the following raw materials: feldspar 45%-65%, glass powder 10%-25%, white clay or high alumina clay 15%-30%, silicon carbide 0.05%-1%; when preparing, first weigh the material, add water to get the slurry; then ball mill the slurry, dry it, and crush it; finally sinter at 1200℃~1300℃ , cooling is enough, but the implementation of this process requires a higher sintering temperature, which consumes a lot of energy, which is not conducive to environmental protection and affects its popularization and application.

The patent with the authorized notification number CN103396150B also discloses a method of using solid waste to prepare foam ceramic self-insulating wall material. The wall material is composed of main materials and admixtures. Waste slag, albite, and bentonite are composed of 25-35%: 19-27%: 20-26%: 17-25%: 1-6%, and 16-20g of admixture is added to every 200g of main ingredients, and after mixing Uniform, sieved, put into the mold, pressed into shape, dried, fired in a strong reducing atmosphere at 1120-1180 ° C, the additives are sintering agent and foam stabilizer, but the implementation of this process requires sintering in a strong reducing atmosphere , the high cost of equipment still affects its popularization and application

[0005] In addition, the preparation of oil well soil foam ceramics currently requires the addition of other additives, such as foaming agents, cosolvents, modifiers, etc., in addition to the basic raw materials oil well soil and glass powder. The addition of these raw materials not only affects the quality of the final product. The performance of foam ceramics also greatly increases the production cost of foam ceramics, which is not conducive to industrial application
