Composite bactericide of nano-silver and polyhexamethylene guanidine and processing technology of composite bactericide

Abstract

The invention relates to a composite bactericide of nano-silver and polyhexamethylene guanidine and a processing technology of the composite bactericide. The composite bactericide comprises the nano-silver, the polyhexamethylene guanidine, dispersing agents, stabilizers, complexing agents and water. The composite bactericide is a water solution, the mass ratio of the nano-silver to the polyhexamethylene guanidine is (1:100)-(1:10000), the total mass of the nano-silver and the polyhexamethylene guanidine accounts for 1%-50% of the total solution mass, the mass of the dispersing agents accounts for 0.1%-10% of the total solution mass, the mass of the stabilizers accounts for 0.1%-10% of the total solution mass, the mass of the complexing agents accounts for 1%-30% of the total solution mass, and the balance is the water. The composite bactericide is high in sterilization 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 silver and polyhexamethylene guanidine. Background technique [0002] Fungicides include organic fungicides and inorganic fungicides. Organic fungicides are used in a small amount and have high sterilization efficiency. However, long-term use makes fungi prone to drug resistance. The use of fungicides needs to continue to increase, and the final effect is getting smaller and smaller. Another weakness is that organic fungicides are prone to failure and have a short efficacy period. Inorganic fungicides have large dosage, low sterilization efficiency and high toxicity. However, inorganic fungicides often have a long duration of efficacy and do not produce drug resistance. Now polyhexamethyleneguanidine is a very effective environmental-friendly organic fungicide. It has very low toxicity and does not cause harm to the human body, but it a...

The dosage of inorganic fungicides is large, the sterilization efficiency is low, and the toxicity is high

However, inorganic fungicides often have a long duration of efficacy and do not produce drug resistance. Now polyhexamethyleneguanidine is a very effective environmental-friendly organic fungicide. It has very low toxicity and does not cause harm to the human body, but it also has the potential to produce resistance. The problem of short duration of drug and drug effect

Silver is a metal that is friendly to the human body. Silver salt fungicides are popular because of their high sterilization rate and long-lasting efficacy. However, silver salts are oxidative fungicides, and improper use can easily cause harm to the human body.
