Household floor heating circulating water system inorganic composite micro-particle protective agent and preparation method of protective agent

Abstract

The invention discloses a household floor heating circulating water system inorganic composite micro-particle protective agent and a preparation method of the protective agent. The preparation methodcomprises the following steps: first adding carbon nanotubes into a mixed acid, performing stirring and refluxing, performing filtering, performing vacuum drying to obtain acidified carbon nanotubes,dispersing the acidified carbon nanotubes into dimethylformamide, dropwise adding thionyl chloride, continuously carrying out a reaction, adding tetrahydrofuran, performing centrifugal separation, performing vacuum drying to obtain acyl chlorination carbon nanotubes, adding the acyl chlorination carbon nanotubes into a diamine, adding a condensing agent and continuously carrying out a reaction, performing washing, performing filtering, performing vacuum drying to obtain aminated carbon nanotubes, then dissolving silver nitrate, ammonia water and anhydrous glucose into water, performing uniformstirring, adding the aminated carbon nanotubes for a reaction, and performing filtration, washing, drying, sintering, and grinding to obtain the aminated carbon nanotube nano silver composite material. The preparation process is simple, and can be industrially produced, and the prepared inorganic composite micro-particle protective agent has multiple effects of scale inhibition, corrosion inhibition, bacteriostasis and anti-clogging.

Description

technical field

[0001] The invention relates to the technical field of water treatment agents, in particular to an inorganic composite microparticle protective agent for household floor heating circulating water systems and a preparation method thereof. Background technique

[0002] At present, most of the protective agents used in the domestic floor heating water circulation system are organic compounds of the benzisothiazolone type, which have a single effect and pollute the water body. Prevent pipe blockage. At the same time, in the floor heating water circulation system, the added organic scale inhibitor will make the water in the system smelly and dirty, which will affect the user's acceptance during the cleaning process of the floor heating system. Contents of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides an inorganic composite microparticle protective agent for domestic floor heating circulating wate...
