Abstract

The invention discloses a preparation method of a conductive geopolymer, comprising the following steps: (1) mixing and stirring metakaolin and graphite to obtain a mixture; (2) adding phosphoric acid and water in sequence, and the mass ratio of phosphoric acid to metakaolin 0.6-0.8:1, stirring, mixing reaction, when stirring until the mixture is thick, stop stirring; (3) compression molding, drying, demoulding, curing, and the conductive geopolymer is obtained. The non-toxic, harmless and environmentally friendly conductive geological polymer material prepared by the invention has the advantages of high strength, fast curing, high temperature resistance, and good electrical conductivity, which can make up for the high price and poor electrical conductivity of various conductive concrete materials that already exist in the building materials market. The shortcomings of the invention can be applied to the fields of road snow removal, indoor heating, chemical industry and building materials respectively, and the prospect is very broad.

Description

technical field [0001] The invention relates to a preparation method of a geopolymer, in particular to a preparation method of a conductive geopolymer. Background technique [0002] In winter, there are often large areas of snowfall in the north of our country, and there are long snow days, which seriously hinders traffic travel, poses a great threat to pedestrian travel safety, and brings great inconvenience to transportation. serious impediment to economic development. The traditional mechanical cleaning method is not clean, and the equipment costs a lot, and the economic benefit is poor. The traditional salt-melt snow removal method will have an impact on the environment. At the same time, the north will adopt the collective heating method, which not only consumes a lot of resources, but also causes damage to the environment. It is also one of the main reasons for the smog. In summer, in the south of our country, there will be a return to the south, which will affect pe...
