, and composite zeolite surface apertures are reduced compared with modified zeolite, this is probably since the AgNO3 adsorbed on zeolite granular surface does not have
Elution completely, the Ag2O being decomposed to form in drying course reunite on its surface, cause zeolite portion aperture to be blocked, therefore silver
Being removed in type antibacterial zeolite particles has the cation exchange position and hole that a certain number of silver are present in antibacterial sorbing material in the form of an ion
Outside road, there is part Ag2O to be present in the surface of material, so as to ensure that silver and Escherichia coli there are enough contacts area.It is modified
In recombination process, most of sodium ion and silver ion are entered inside zeolite by ion exchange, and composite zeolite denitrogenation is to lean on zeolite
With NH4+ ion exchange occurs for the cations such as the sodium ion in structure, and dephosphorization is the electrostatic suction by the hydrous zirconia gel of zeolite surface
Attached, antibacterial is because the loading of the antibacterial Ag ions of bactericidal property, applies in the preparation of synthetic resin of the present invention, in silane idol
Under the action of joining agent KH-560, realize and carry out grafting with the major ingredient of synthetic resin and combined, effectively increase the anti-of synthetic resin
Bacterium performance.

Can, while the antibacterial humidification of antibacterial modified auxiliary agent is make use of, wherein antibacterial modified auxiliary agent is by by natural zeolite and chlorination
Sodium solution is uniformly mixed, and stirring, filtering means dehydration, drying, then roasts, and it is molten to be subsequently placed in the lanthanum chloride that mass fraction is 4-8%
In liquid, stirring, filtering means dehydration, drying, then roasts, is subsequently placed in silver nitrate solution, stirs, material a is obtained after drying；Will
Material a, ethyl orthosilicate, vinyltriethoxysilane and ammonium hydroxide are uniformly mixed, and stirring, vacuum filter, is washed with absolute ethyl alcohol
Wash, after then adding acetylbutyrylcellulose mixing, stirring obtains antibacterial modified auxiliary agent, and zeolite surface has substantial amounts of ball thing to deposit
, and composite zeolite surface apertures are reduced compared with modified zeolite, this is probably due to adsorbing the AgNO on zeolite granular surface3No
Elution completely, the Ag being decomposed to form in drying course2O reunites on its surface, causes zeolite portion aperture to be blocked, therefore silver
Being removed in type antibacterial zeolite particles has the cation exchange position and hole that a certain number of silver are present in antibacterial sorbing material in the form of an ion
Outside road, there is part Ag2O is present in the surface of material, so as to ensure that silver and Escherichia coli have enough contacts area.It is modified
In recombination process, most of sodium ion and silver ion are entered inside zeolite by ion exchange, and composite zeolite denitrogenation is to lean on zeolite
The cations such as the sodium ion in structure and NH4+Generation ion exchange, dephosphorization are the electrostatic suctions by the hydrous zirconia gel of zeolite surface
Attached, antibacterial is because the loading of the antibacterial Ag ions of bactericidal property, applies in the preparation of synthetic resin of the present invention, in silane idol
Under the action of joining agent KH-560, realize and carry out grafting with the major ingredient of synthetic resin and combined, effectively increase the anti-of synthetic resin
Bacterium performance.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
