Problems solved by technology

Since silver ions have the strongest antibacterial effect among the several metal ions used to prepare inorganic antibacterial agents, and are easily absorbed and recombined by inorganic carriers, the inorganic antibacterial agents are mostly composed of silver ions; silver ions not only easily cause discoloration of the product, but also It also increases the cost of inorganic antibacterial agents; secondly, the physical properties of inorganic antibacterial agent powders, such as powder fineness, cannot meet the application requirements well due to problems such as coarse particles and unreasonable distribution.

Embodiment

[0029] 1. Place 250kg of natural stilbene carrier material with a total amount of cation exchange of 100-130mmol / 100g, a fineness of 300-400 mesh, and a stilbite content of 75%-85%, and 250kg of deionized water in the ultra-fine grinding system of the wet stirring mill Inside, stir for 15 minutes by a mixer with a high-speed stirring effect, and then add 6.25 kg of sodium hexametaphosphate solution with a solution concentration of 20% to make a slurry;

[0030] 2. Start the ultra-fine grinding system of the wet stirring mill, and grind the prepared slurry until the content of less than 2 μm is greater than 90% according to the circular grinding method;

[0031] 3. Import 400kg of ground slurry into the exchange reactor, the ground slurry contains 200kg of natural stilbite carrier material and 200kg of deionized water;

[0032] 4. add deionized water 400kg in the exchange reactor, make the ratio of natural stilbite carrier material (kg) and water yield (kg) in the exchange reac...

Abstract

The present invention provides a preparation method of stilbite carrier zinc series in organic antimicrobial agent. Said invented inorganic antibacterial agent is not limited by physical environment, has strong antibacterial action, good persistent availability, broad-spectrum antibacterial property and good compatibility for making other products. It can solve the product discoloration problem due to addition of antimicrobial agent, can raise the fineness of inorganic antimicrobial agent powder body, and can be uniformly distributed in the product, at the same time it can greatly reduce cost of inorganic antimicrobial agent.

Description

Technical field [0001] The invention relates to a preparation method of an inorganic antibacterial agent, in particular to a preparation method of a stilbite carrier zinc-based inorganic antibacterial agent. Background technique [0002] With the growth of human material wealth and the overall progress of society, people are more and more concerned about environmental issues, and pay special attention to the problems caused by the environment that affect human health and quality of life. It has become a social consensus to reduce and effectively prevent the interference and harm of microorganisms in human settlements to human life, and to alleviate the resulting bacterial infection and disease epidemic. In production sites, public places and human settlements, these hazards of environmental microorganisms even endanger human life. Common measures to control environmental microorganisms, such as air purification, ultraviolet radiation, ozone sterilization, and the use of org...
