Problems solved by technology

However, the hydrophilic group of diquaternary ammonium salt makes it water-soluble, and it is easy to be leached by water in outdoor or other occasions exposed to running water; in addition, it is difficult to form a uniform mixed phase with hydrophobic organic matter
These deficiencies in performance have affected its scope of use

Embodiment 1

[0026] Embodiment 1: Preparation of double quaternary ammonium salt pillared montmorillonite fungicide

[0027] 1.1 Weigh 10 kg of montmorillonite, together with 1 kg of NaCl, add 30 kg of water and stir evenly to make a suspension slurry, react for 6 hours, and stir once every 0.5 hours;

[0028] 1.2 Wash twice after centrifugal dehydration, add 30 kg of water and stir evenly to re-slurry, add 0.5 kg of 2-(2-phenoxyethoxy)-ethyltrimethylammonium chloride (biquaternary ammonium salt), and stir After uniform reaction for 12 hours, stirring every 1 hour;

[0029] 1.3 After centrifugal dehydration, wash twice, dehydrate again, and dry at 70°C. The product obtained is biquaternary ammonium pillared montmorillonite fungicide, which is ground to less than 300 mesh and stored in bags.

Embodiment 2

[0030] Embodiment 2: Preparation of double quaternary ammonium salt pillared beidellite fungicide

[0031] 2.1 Weigh 10kg beidellite together with 1.5kg NaNO 3 , add 90 kg of water and stir evenly to make a suspension slurry, react for 8 hours, and stir once every 0.5 hours;

[0032] 2.2 Wash once after centrifugal dehydration, add 40 kg of water and stir evenly to re-slurry, add 1.0 kg of N, N-bis(dodecyldimethyl)-3-oxa-1,5-pentane dichloride Ammonium (diquaternary ammonium salt), after stirring evenly, reacted for 10 hours, stirring once every 0.5 hour;

[0033] 2.3 After centrifugal dehydration, wash once, dehydrate again, and dry at 60°C. The product obtained is bisquaternary ammonium pillared beidellite fungicide, which is ground to less than 300 mesh and stored in bags.

Embodiment 3

[0034] Embodiment 3: Preparation of double quaternary ammonium salt pillared rectorite fungicide

[0035] 3.1 Weigh 10 kg rectorite, together with 0.5 kg Na 2 SO 4 , add 40 kg of water and stir evenly to make a suspension slurry, react for 10 hours, and stir once every 1 hour;

[0036] 3.2 Wash twice after centrifugal dehydration, add 50 kg of water and stir evenly to re-slurry, add 1.5 kg of N, N-bis(dodecyldimethyl)-3-aza-1,5-pentane dichloride Ammonium (diquaternary ammonium salt), after stirring evenly, reacted for 6 hours, stirring once every 0.5 hour;

[0037] 3.3 After centrifugal dehydration, wash twice, dehydrate again, and dry at 78°C. The product obtained is biquaternary ammonium pillared rectorite fungicide, which is ground to less than 300 mesh and stored in bags.

Abstract

The present invention discloses a diquaternary ammonium salt column-supported smectite and vermiculite bactericidal agent and its preparation method. Said bactericidal agent uses smectite mineral and vermiculite as carrier, and utilizes soldium-ionization reaction and diquaternary cationic column supportion reaction to obtain the invented bactericidal agent product. The content of diquaternary ammonium salt in the bactericidal agent is 5-20%, and the diquaternary cations are fixed in the interlamellar position of the smectite and vermiculite. Said bactericidal agent can be used as antibacterial mildew-proofing additive in organic polymer, environmental disinfecting agent, anti-corrosion additive of industrial equipment and disinfecting agent of circulation cooling water.

Description

technical field [0001] The invention relates to a fungicide and a preparation method thereof. More specifically, the present invention relates to a kind of double quaternary ammonium salt pillared smectite, vermiculite bactericide and preparation method thereof. Background technique [0002] Biquaternary Ammonium Salt (Biquaternary Ammonium Salt) has strong bactericidal and fungicidal effects, and has special effects on sterilizing and algae-killing industrial circulating water in petrochemical plants, chemical fertilizer plants, oil refineries, pharmaceutical plants, etc., as well as power plants and mines. It has been widely used in the treatment of circulating cooling water in oil field water injection, chemical industry, medicine, electric power and metallurgy industries. The bactericidal effect of quaternary ammonium salts is achieved by denaturing bacteria and fungal proteins and destroying them; affecting metabolic processes such as glucose respiration; or affecting ...
