Problems solved by technology

But at the same time, as the patent says, the simple charge loading of nano-silver on the surface is still easy to cause the oxidation-reduction phenomenon of silver, which leads to the inactivation of the antibacterial effect of nano-silver, and cannot achieve long-term effective microbial protection. The cohesion of sugar itself is not good, the retention rate in some places of use is low, the timeliness of microbial protection is poor, and it is easy to lose

Abstract

The invention discloses a long-acting microbial protection composition. The composition is prepared from, by weight, 10 to 20 parts of an inorganic sol, 30 to 40 parts of a macromolecular emulsion, 30 to 45 parts of an alcoholic hydroxyl compound, 5 to 15 parts of a modified guanidine salt, 1 to 8 parts of an auxiliary agent, 1 to 5 parts of a regulator and 100 to 200 parts of deionized water. The prepared long-acting microbial protection composition has a good combination effect of an inorganic antibacterial agent and an organic antibacterial agent, the antibacterial and antiviral effects of the microbial protection composition of the composition are obviously improved through the synergistic effect of the inorganic antibacterial agent and the organic antibacterial agent, and the long-acting microbial protection composition has good applicability, can be used in various occasions; is especially suitable for a humid environment, can achieve effective microbial protection, and keep production and living environments clean and reducing the hidden danger of human life health, and meanwhile, the prepared composition has good microbial protection timeliness, is suitable for being popularized in the field of daily chemical products, and has wide development prospects.

Description

technical field [0001] The invention relates to the field of daily chemical products, in particular to a long-acting microbial protection composition and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of living standards, people's requirements for the living environment have shown an increasing trend year by year in recent years. Among them, people's requirements for the protection of microorganisms are one of the fastest growing areas. Microorganisms are organisms such as bacteria, fungi, and viruses that we can come into contact with in our daily life. They are ubiquitous in our daily life environment. In people's normal production and living activities, these microorganisms often come into close contact with human body parts such as hands, nose, mouth and ears. It can cause a series of health problems to the human body. [0003] In addition to avoiding the invasion of microorganisms through timely cle...
