Problems solved by technology

[0002] Fungicides include organic fungicides and inorganic fungicides. The dosage of organic fungicides is small and the sterilization efficiency is high. However, long-term use makes fungi prone to drug resistance. The disadvantage is that organic fungicides are prone to failure, cannot last for too long, and cannot sterilize or inhibit bacteria for a long time
Inorganic fungicides have a large dosage and low sterilization efficiency, but inorganic fungicides often last for a long time a...

Embodiment 1

[0025] Weigh 5 grams of nanometer copper, 25 grams of polyhexamethyleneguanidine, 1 gram of dodecyltrimethylammonium bromide, 1 gram of aminotrimethylene phosphonic acid, 5 grams of glycine, and the rest as water. Dissolve polyhexamethylene guanidine in water at room temperature, then add dodecyltrimethylammonium bromide, glycine and aminotrimethylenephosphonic acid, stir well, and finally add nano-copper, stir well and mix well.

Embodiment 2

[0027] Weigh 10 grams of nano-copper, 20 grams of polyhexamethylene guanidine, 2 grams of cetyltrimethylammonium bromide, 2 grams of sodium ethylenediamine tetramethylene phosphonate, 15 grams of glutamic acid, and the rest as water . Dissolve polyhexamethylene guanidine in water at room temperature, then add cetyltrimethylammonium bromide, glutamic acid and sodium ethylenediamine tetramethylene phosphonate, stir well, and finally add nano-copper, stir well Just mix well.

Embodiment 3

[0029] Weigh 15 grams of nano-copper, 20 grams of polyhexamethylene guanidine, 3 grams of polyoxyethylene butylphenol ether, 1 gram of pentasodium aminotrimethylene phosphonate, 20 grams of alanine, and the rest is water. Dissolve polyhexamethylene guanidine in water at room temperature, then add polyoxyethylene butylphenol ether, alanine and pentasodium aminotrimethylene phosphonate, stir well, and finally add nano-copper, stir well and mix well.

Abstract

The invention relates to a composite bactericide of nano copper and polyhexamethylene guanidine and a processing technic. The composite bactericide consists of nano copper, polyhexamethylene guanidine, a dispersant, a stabilizer, a complexing agent and water. The composite bactericide is an aqueous solution. The weight ratio of nano copper and polyhexamethylene guanidine is (1:1)-(1:20) and the total weight of nano copper, polyhexamethylene guanidine accounts for 2-50% by mass of the total solution, the dispersant accounts for 0.1-10% by mass of the total solution, the stabilizer accounts for 0.1-30% by mass of the total solution and the complexing agent accounts for 1-30% by mass of the total solution, and the rest of the solution is water. The composite bactericide is high in sterilizing efficiency and low in cost.

Description

technical field [0001] The invention relates to the technical field of material chemistry, in particular to a composite bactericide of nano copper and polyhexamethylene guanidine and a processing technology. Background technique [0002] Fungicides include organic fungicides and inorganic fungicides. The dosage of organic fungicides is small and the sterilization efficiency is high. However, long-term use makes fungi prone to drug resistance. The disadvantage is that organic fungicides are prone to failure, cannot last for too long, and cannot sterilize or inhibit bacteria for a long time. The dosage of inorganic fungicides is large, and the bactericidal efficiency is low. However, inorganic fungicides often last for a long time and do not produce drug resistance. Now polyhexamethylene guanidine is a very effective environment-friendly organic fungicide, but it also has the disadvantages of easy to produce drug resistance and short duration of drug effect. Copper salt fung...
