A kind of instant antibacterial masterbatch and preparation method thereof

Abstract

The invention provides an instant antibacterial masterbatch and a preparation method thereof, which belong to the field of antibacterial technology. An instant antibacterial masterbatch, prepared by the following method: S01: the guanidinium salt polymer and polyethylene glycol are prepared into a composite antibacterial agent according to the method of physical mixing in proportion; S02: the guanidinium salt polymer / polyethylene glycol Diol antibacterial agent mixed with zinc-loaded antibacterial agent; S03: guanidinium salt polymer / polyethylene glycol / zinc-loaded antibacterial agent three-component composite antibacterial agent and water, surfactant, builder, carboxymethyl cellulose After the sodium and essence are mixed evenly, it is extruded through a strand granulator through banburying and kneading, and extruded into granules. S04: Coating treatment is performed with sodium stearate micropowder. An instant antibacterial masterbatch with good fluidity and no adhesion is prepared, which can be quickly dissolved after encountering water, and has the function of rapid sterilization and sterilization.

Description

technical field [0001] The invention relates to the field of antibacterial technology, in particular to an instant antibacterial masterbatch which can be quickly dissolved in water and has the functions of sterilizing and degerming and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's economic level, the hygiene requirements in life are getting higher and higher. When washing clothes, consumers often add a certain amount of disinfectant. Common disinfectants on the market generally contain active ingredients such as sodium hypochlorite and p-chloro-m-xylenol (PCMX), but sodium hypochlorite has strong oxidizing properties and may cause clothing to fade, while p-chloro-m-xylenol (PCMX) It is not easy to dissolve in water and is inconvenient to use. The manufacturer can only make it into a liquid state by adding a large amount of surfactants, alcohols and other ingredients. The effective content is in the range of a fe...

AI Technical Summary

Problems solved by technology

[0004] Water-soluble guanidine salt polymer is used as the bactericidal component, and the bactericidal effect can be achieved by adding a small amount each time, but polyhexamethylene guanidine hydrochloride and polyhexamethylene biguanide hydrochloride are easy to absorb moisture, and they are sold in the market Polyhexamethyleneguanidine hydrochloride usually needs to be sealed and stored. After opening, it will quickly absorb moisture and agglomerate, and the surface will be sticky. It is difficult for consumers to take it directly when using it, and it is inconvenient to operate; Guanidine hydrochloride has high safety requirements, and it is not good for non-professionals to directly contact with hands or skin, and dusty samples will generate dust when poured, which is inhaled by people, which is not suitable for health. The amount of powdered products added is not easy to control, more or less, difficult to measure

[0005] If polyhexamethyleneguanidine hydrochloride, polyhexamethylenebiguanidine hydrochloride, etc. are made into aqueous solutions, there is also the problem of inaccurate measurement, and plastic containers should be used for liquid packaging, resulting in plastic packaging recycling or plastic White pollution problem, in addition, most of it is water during transportation, high energy consumption, and low effective transportation efficiency
