Energy-saving and environment-friendly brick and preparation method

Abstract

The invention discloses an energy-saving and environment-friendly brick and a preparation method. A brick body comprises cement, fly ash, waste plastics, waste fiber, plant straw, river bottom sludge, calcium carbonate, glass microbeads, quartz powder, wood chips and high-adhesion attapulgite clay. The preparation method comprises the steps of evenly mixing the cement, the fly ash, the river bottom sludge, the calcium carbonate and the quartz powder, adding the smashed waste plastics, waste fiber, plant straw and the wood chips and performing uniform mixing, adding water and performing mixing; adding the glass microbeads, the quartz powder and the high-adhesion attapulgite clay, and perform uniform mixing; forming the mixture, placing the mixture in a steam curing system for steam curing, and obtaining the energy-saving and environment-friendly brick. The energy-saving and environment-friendly brick has the advantages of being low in manufacturing cost and light in mass. Waste materials are adopted to replace soil sand and pebbles and the like, environmental disruption caused by overexploitation is avoided, waste reutilization is implemented, and the brick body further has good effects of water prevention and heat insulation.

Description

technical field [0001] The invention relates to the technical field of environment-friendly building materials, in particular to an energy-saving and environment-friendly brick and a preparation method thereof. Background technique [0002] Bricks are one of the indispensable materials in construction, and in the prior art, the bricks that are widely used are made of earth, sand, pebbles and water as the main raw materials. As the demand for bricks increases The bigger it is, therefore, many brick factories have adopted destructive development of the natural environment in order to expand production scale and increase output, resulting in excessive mining of soil, sand and pebbles in many brick production bases, which seriously affects the natural environment. [0003] At present, the production of self-insulating concrete composite blocks only needs to use about 40% waste coal ash as admixture, cement, lime, gypsum, and adhesives as cementing materials; gravel, sand, and ce...

[0002] Brick is one of the indispensable materials in construction, and in the prior art, the bricks that are widely used are made of earth, sand, pebbles and water as the main raw materials. As the demand for bricks increases The bigger the bigger, therefore, in order to expand the production scale and increase the output, many brick factories have adopted destructive development of the natural environment, resulting in the excessive mining of mud, sand and pebbles in many brick production bases, which seriously affects the natural environment

[0003] At present, the production of self-insulating concrete composite blocks only needs to use about 40% waste coal ash as admixture, cement, lime, gypsum, and adhesives as cementing materials; gravel, sand, and ceramsite as aggregates, and groundwater Or tap water as the mixing liquid, made of organic or inorganic chemical raw materials as the activator, and the density of the finished product is above 800kg / m3. This scheme disposes of a certain amount of industrial waste (about 40%), and consumes a large amount of industrial products and parts Non-renewable resources have higher costs
