Example Embodiment

[0017] The embodiments of the present invention will be described in detail below.

[0018] A kind of light shale brick, which is composed of the following raw materials containing 60% by weight: 60% shale, 20%-35% organic flammable auxiliary materials, 5%-20% other auxiliary materials, and water at a temperature of 40℃~45℃. %~60%, crush the shale to 100 meshes, add water, organic flammable auxiliary materials and other auxiliary materials to the shale powder, stir evenly, stir evenly and let stand for 1 hour-1.5 hours to make a billet. Dry it, put it in 950℃~1150℃ for roasting and keep it for 8-12 hours.

[0019] The other auxiliary materials are made by mixing quicklime and aluminum powder, and the mass percentages are: quicklime 87.5%-90%, aluminum powder 10%-12.5% ​​or the other auxiliary materials are made by mixing quicklime and iron powder, The mass percentages are: quicklime 87.5%-90%, iron powder 10%-12.5%.

[0020] The organic flammable auxiliary material is a powder of s...

Abstract

The invention provides a light shale brick and a production method of the light shale brick. The light shale brick is characterized by comprising the following raw materials in percentage by weight: 60% of shale, 20 to 35% of organic matter flammable accessory, 5 to 20% of other accessories, and 50 to 60% of water at 40 to 45 DEG C; the production method comprises the steps of crushing the shale, adding the water, the organic matter flammable accessory and other accessories into the shale powder; uniformly agitating; preparing into blanks; parching the blank; roasting at 950 to 1,150 DEG C; and keeping for 8 to 12 hours so as to obtain the product; the other accessories are prepared by mixing 87.5% to 90% of shell and 10 to 12.5% of aluminum powder based on mass percentage, or prepared by mixing 87.5 to 90% of shell and 10 to 12.5% of iron powder; and the organic matter flammable accessory is the powder of one or the mixture of any two of saw dust, plant straw, urban garbage, fallen leaves, couch grass, shrub, firewood, branch and wood dust. The light shale brick provided by the invention has the advantages of heat preservation, heat insulation, fire proofingness, cracking prevention, sound insulation, low self weight, high anchoring performance, low cost, and light weight.

Description

technical field [0001] The invention relates to a lightweight shale brick with light weight, heat preservation, heat insulation, fire prevention, crack prevention, sound insulation and other properties and a production method thereof. Background technique [0002] In the patent document of 200510022384.8, the microporous agent used in the production of shale bricks is mainly polystyrene and expanded perlite particles, and the solid form of polystyrene is safe and non-toxic. But EPS particles will give off pentane vapor during storage. Pentane is extremely flammable and can form explosive mixtures with air. Heating polystyrene-type polymers can release styrene monomer. Styrene is a dangerous substance. Polystyrene powder can irritate the respiratory tract and skin. Moreover, the price of expanded perlite is high, which increases the cost of construction. Therefore, compared with the production method of sintered shale bricks, the production of lightweight shale bricks ...
