Embodiment Construction

[0016] A water-resistant and moisture-proof refractory brick, made of the following raw materials in weight (kg): petroleum refining waste oil sludge 36, bauxite tailings 23, glauconite 18, natural colored sand 17, natural zeolite 22, sodium alginate 6 , Alum stone 12, coal-fired boiler ash 16, ferric chloride 4.5, acrylic acid ribosan 8, polymethylsilsesquioxane spherical micropowder 9, dihydrate spherical calcium chloride 7, waste mortar 25, quicklime 17.

[0017] A method for preparing a water-resistant and moisture-proof refractory brick is characterized in that it consists of the following steps:

[0018] (1) Mix bauxite tailings, glauconite, natural zeolite, and coal-fired boiler ash evenly, pulverize, pass through an 80-mesh sieve, calcinate at 880°C for 1.5h, cool to room temperature, and dry ball mill at 600r / min for 15min. Then add the ball-milled powder into the hydrochloric acid solution with a mass fraction of 35% according to the solid-to-liquid ratio of 1:6, hea...

Abstract

The invention discloses a water-resistant moisture-proof refractory brick and a preparation method thereof. The refractory brick is prepared from the following raw materials by weight: 33-41 parts of petroleum refined waste oil sludge, 17-29 parts of bauxite tailings, 14-22 parts of glauconite, 15-20 parts of natural colored sand, 16-28 parts of natural zeolite, 4-7 parts of sodium alginate, 10-15 parts of alunite, 12-19 parts of coal-fired boiler ash, 3-6 parts of ferric chloride, 5-10 parts of acrylic nuclear glycan, 7-12 parts of polymethylsilsesquioxane spherical micropowder, 5-10 parts of spherical calcium chloride dihydrate, 20-30 parts of waste mortar, and 13-21 parts of quick lime. The method provided by the invention employs natural colored sand, alunite, petroleum refined waste oil sludge, ferric chloride, acrylic nuclear glycan, polymethylsilsesquioxane spherical micropowder, spherical calcium chloride dehydrate and other raw materials for mutual compounding, greatly reduces the water absorption of the refractory brick, and does not affect the flexural strength, compressive strength and refractoriness of the refractory brick. The refractory brick provided by the invention has the advantages of excellent water resistance and moisture proofness, and high refractoriness, and is suitable for wall building under a moist environment.

Description

technical field [0001] The invention relates to a water-resistant and moisture-proof refractory brick and a preparation method thereof, belonging to the field of refractory materials. Background technique [0002] All materials that can resist high temperature and the physical and chemical effects produced at high temperature are collectively called refractory materials. Refractory materials are widely used in various fields of national economy such as metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power, boiler, light industry, electric power, military industry, etc., and are essential materials to ensure the production operation and technological development of the above industries , plays an irreplaceable important role in the development of high temperature industrial production. Refractory materials are generally divided into two types, namely unshaped refractory materials and shaped refractory materials. Among them, shaped refractory mat...
