Embodiment 1

[0027] Embodiment 1: Preparation of copper-loaded sodium-based rectorite bactericide and bacteriostatic agent

[0028] Dissolve 10g of CuSO4·5H2O into 1000ml of water, add 100g of nanometer sodium-based rectorite with a purity of 90%, stir well, heat to 65°C, and react for 18 hours. Centrifuge and dehydrate the above slurry, and dry the filter cake at 60°C until the water content is 10%, then pulverize, pass through a 100-mesh sieve, and pack for use. The copper-loaded rectorite bactericide and antibacterial agent prepared according to the above steps have a copper element content of 2.2%.

Embodiment 2

[0029] Embodiment 2: Preparation of copper-loaded calcium-based rectorite bactericide and bacteriostatic agent

[0030] Calcium-based rectorite ore, the purity reaches 92% after separation and purification. Weigh 100g of purified magnesium-based rectorite, add 900ml of water, and stir evenly to make a suspension. Add 10g of NaCl, stir evenly and heat to about 105°C, ion exchange reaction for 8 hours, stirring from time to time. Centrifuge to precipitate, and decant the supernatant. Add 1000ml of water to the filter cake, stir evenly, then centrifuge to settle, and pour off the supernatant. Repeat 2 times. Add 6g of CuSO4·5H2O, stir well, heat to about 65°C, and stir for 8 hours. Vacuum filter. The filter cake is dried at 80°C until the water content is less than 10%, crushed, passed through a 100-mesh sieve, and packed for use. The prepared copper-loaded rectorite bactericide and antibacterial agent have a copper element content of 1.36%.

Embodiment 3

[0031] Embodiment 3: Preparation of copper-loaded magnesium-based rectorite bactericide and bacteriostatic agent

[0032] Calcium-based rectorite ore, the purity reaches 95% after separation and purification. Weigh 80g of purified calcium-based rectorite, add 920ml of water, and stir evenly to make a suspension. Add 5g of NaCl, stir evenly and heat to about 30°C, ion exchange reaction for 24 hours, stirring from time to time. Centrifuge to precipitate, and decant the supernatant. Add 1000ml of water to the filter cake, stir evenly, then centrifuge to settle, and pour off the supernatant. Repeat 2 times. Add 1.4 g of CuSO4·5H2O, stir well, heat to about 30°C, and stir for 12 hours. Vacuum filter. The filter cake is dried at 75°C until the water content is less than 10%, crushed, passed through a 100-mesh sieve, and packed for use. The copper element content of the prepared copper-loaded rectorite bactericide and antibacterial agent is 0.4%.

Abstract

The invention discloses a copper-loaded rectorite germicide and bacteriostat and the preparation method. The germicide and bacteriostat are composed of rectorite and bivalent cupric salt, wherein the rectorite occupies 77 percent to 99 percent according to the percentage by weight, the others are cupric salt; the copper element accounts for 0.4 percent to 7.5 percent of the gross rectorite and cupric; the rectorite is a nami sodium rectorite with a purity of more than 90 percent or a sodium rectorite with a purity of more than 90 percent. The preparation method is that the rectorite and cupric salt are weighed up according to the quantity, and then cupric salt solution is configured, the rectorite is put into the cupric salt solution, under the temperature of 30 DEG C to 105 DEG C, the time of ion exchange adsorption is 8 to 24 hours, subsequently, the copper-loaded rectorite is got after the centrifugation or filtration. The germicide has the functions of slow release and antibacterium, safety and environmental protection, thereby which can widely be applicable for the disinfection and antibacterial treatment in public places, and also can be used for antibacterium and stuffing in the industries of paint, plastic and textiles, and can be processed into the feed additives which can control the gastrointestinal diseases of animal.

Description

technical field [0001] The invention relates to a bacteriostatic and bactericidal agent containing copper ions, in particular to a copper-loaded rectorite bactericidal and bacteriostatic agent and a preparation method thereof. The antibacterial and bactericidal agent can be used for disinfection and antibacterial treatment of public places and environments; it can also be used as antibacterial fillers in coatings, plastics, textiles and other industries; it can also be processed into feed additives for controlling animal digestive tract diseases. Background technique [0002] Among the antibacterial metal ions, copper ions have the advantages of broad antibacterial spectrum, high bactericidal efficiency, not easy to produce drug resistance, and long validity period. However, in the application of animal disinfection and environmental disinfection, direct use of copper-containing compounds such as copper sulfate as fungicides will consume more copper and the cost of use will ...
