Environmental-protective light-weight ceramic granule solidifying agent and preparation method thereof

Abstract

The invention belongs to the technical field of ceramic granules and especially relates to an environmental-protective light-weight ceramic granule solidifying agent and a preparation method thereof. The environmental-protective light-weight ceramic granule solidifying agent includes following raw materials: by weight: 5-9 parts of starch xanthate, 1-3 parts of walnut shell activated charcoal, 5-9 parts of bentonite, 1-3 parts of a chitosan / graphene composite material, 10-12 parts of dextrin, 10-15 parts of glycerin monostearate, 5-9 parts of magnesium oxide and 20-35 parts of fly ash. The environmental-protective light-weight ceramic granule solidifying agent is used for modifying a ceramic granular raw material to achieve compatibility of the raw materials, thereby forming a homogenized dispersing system. The solidifying agent can change a physical situation before and can solidify organic and inorganic pollutants in the raw materials, thereby controlling pollution.

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.
