A kind of environment-friendly lightweight ceramsite curing agent and preparation method thereof

Abstract

The invention belongs to the technical field of ceramsite, and in particular relates to an environment-friendly lightweight ceramsite curing agent and a preparation method thereof. The environment-friendly lightweight ceramsite curing agent comprises the following raw materials in parts by weight: starch xanthate 5-9 1-3 parts of walnut shell activated carbon, 5-9 parts of bentonite, 1-3 parts of chitosan-graphene composite material, 10-12 parts of dextrin, 10-15 parts of glyceryl monostearate, 5 parts of magnesium oxide ~9 parts, 20-35 parts of fly ash; the environment-friendly lightweight ceramsite curing agent of the present invention is used to modify the ceramsite raw materials, so that each raw material can reach the purpose of mutual compatibility and form a homogeneous dispersion system. It changes the previous physical state, and can solidify and stabilize the organic and inorganic pollutants in the raw materials to achieve the purpose of pollution control.

Description

technical field [0001] The invention relates to the technical field of curing agents, in particular to an environment-friendly lightweight ceramsite curing agent and a preparation method thereof. Background technique [0002] Ceramsite is a ceramsite particle, most of its appearance features are round or oval spheres, but there are also some gravel-like ceramsites that are not round or oval spheres, but irregular gravel. The shape of ceramsite varies from process to process. Ceramsite can solve engineering problems such as quality, fire prevention, heat insulation, and heat preservation, and can also be used for horticultural and hydroponic planting. [0003] The existing ceramsite uses sludge as the main raw material, kaolin, fly ash, etc. as auxiliary materials. Under certain process conditions, the decarburization and swelling of sludge are controlled, and sludge is often taken from urban domestic sewage. , printing and dyeing sewage, electroplating wastewater and other...

AI Technical Summary

Problems solved by technology

[0003] The existing ceramsite uses sludge as the main raw material, kaolin, fly ash, etc. as auxiliary materials. Under certain process conditions, the decarburization and swelling of sludge are controlled, and sludge is often taken from urban domestic sewage. , printing and dyeing sewage, electroplating wastewater and other treated sludge contain a large amount of organic pollutants and inorganic pollutants, and it is very difficult to eliminate organic pollutants and inorganic pollutants in sludge, especially for heavy metal pollutants. Therefore, sludge The produced ceramsite still has certain pollution and toxicity, which poses great safety hazards to society and the environment, and is not conducive to the sustainable development of society and the environment.

[0004] At the same time, due to the complex chemical composition and microstructure of raw materials, in order to meet the purpose of reducing the weight of buildings, there is an urgent need for a curing agent that can modify ceramsite raw materials to control pollution and reduce ceramsite weight.
