Fluorite slag aerated brick and preparation method thereof

Abstract

The invention provides a fluorite slag aerated brick which is prepared through processing raw materials in part by weight: 20 to 30 parts of fluorite slag, 25 to 30 parts of sand, 5 to 10 parts of cement, 4 to 6 parts of modified attapulgite, 5 to 10 parts of ceramsite, 5 to 10 parts of waste in ceramic factories, 5 to 10 parts of light calcium powder, 10 to 15 parts of lime, triethanolamine, 4 to 5 parts of gypsum, 0.02 to 0.08 part of aluminum powder, oxidized paraffin wax soap, 0.01 to 0.02 part of calcium bicarbonate, 2 to 3 parts of lava, 1 to 2 parts of lignocellulose, 0.3 to 0.5 part of sodium silicate, 0.03 to 0.05 part of borax, 1 to 2 parts of sodium hexametahposphate, 1 to 2 parts of hydroxypropyl methyl cellulose sodium, and 1 to 2 parts of superfine polyvinyl alcohol, wherein the weight of the triethanolamine is 0.1 to 0.3 percent of that of the lime, and the weight of the oxidized paraffin wax soap is 3 to 5 percent of that of the aluminum powder. Fluorite slag is added in the raw materials of the aerated brick, meanwhile, other conventional additives and modified nano additives are added, a proper process is adopted to manufacture the aerated brick, and the aerated brick is low in cost and good in performance, achieves the circular economy effect of turning waste into valuable, reduces the pollution, is light in weight, high in heat insulation property, good in sound-absorbing effect, and high in strength, and can be used as a non-bearing wall or a bearing wall.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fluorite slag aerated brick and a preparation method thereof. Background technique [0002] The aerated concrete block is a solid block made of cement, slag, sand, lime, etc., added with an air-generating agent, stirred and formed, and autoclaved. According to the application, the aerated concrete can be divided into non-load-bearing blocks , load-bearing blocks, insulation blocks, wall panels and roof panels five. [0003] Aerated brick has the advantages of light bulk density, high thermal insulation performance, good sound absorption effect, certain strength and machinability, etc. It is one of the earliest and most widely used lightweight wall materials in my country. [0004] Under the background of the increasingly important protection of energy and natural resources in the world, with the adjustment of industrial policies and the improvement of environmental protection...
