Abstract

The invention discloses a silt-sintered energy storage brick and a production process thereof. The energy storage brick comprises the following raw materials in parts by weight: 20-30 parts of urban silt, 20-35 parts of ceramsite, 50-80 parts of nano-sized calcium carbonate, 30-45 parts of paraffin, 60-85 parts of a clayey raw material, 2-8 parts of an inorganic flame retardant and 30-50 parts of a phase-change energy storage material, wherein the phase-change energy storage material comprises the following raw materials in parts by weight: 40-60 parts of Portland cement, 20-30 parts of fly ash, 5-10 parts of aluminum oxide and 30-45 parts of n-butyl stearate. A preparation method of the energy storage brick comprises the following steps: blending, mixing, performing hot pressing and firing by the conventional method. The energy storage brick has good compressive strength and abrasive resistance, is strong in corrosion resistance and heat storage and refrigeration capacity, fire-proof and flame-retardant, and has a certain economic benefit.

Description

technical field [0001] The invention relates to the field of environment-friendly building materials, in particular to a silt sintered energy storage brick and a production process thereof. Background technique [0002] Urban silt is the inevitable product of sewage treatment plants and sewage treatment. After discharge, it will directly cause secondary pollution to water bodies and the atmosphere, which not only reduces the effective treatment capacity of the sewage treatment system, but also poses a serious threat to the ecological environment and human activities. . At present, there is an urgent need to formulate and improve a series of supporting standards, such as the relevant standards for fertilizers, building materials, and construction soil for sludge resource use, and the safety of sludge needs to be carefully studied. [0003] At present, using sludge incineration ash as an admixture of fired bricks is one of the important ways to recycle urban sludge, but due t...
