Problems solved by technology

[0005] The technical difficulty here is: firstly, the chemical bond of the molecule is very strong, breaking it requires correct measures and a lot of energy; secondly, after the physical molecular chain is broken, the hinge needs to be positively charged; thirdly, the new material derived have to be machinable, otherwise this new material is useless

Embodiment 1

[0034]Mix 45Kg of quaternary ammonium salt (benzalkonium chloride) with 15Kg of polyamine (ethylenediamine) at about 60°C, heat up to 190-210°C at a speed of 10°C / 15min, react for 40-50 minutes, and then mix 20Kg of guanidine Salt (guanidine carbonate) is added and mixed, and when the temperature is lowered to 125-130°C, 20Kg of cetyl alcohol polyoxyethylene ether and other raw materials are added, mixed for 30 minutes, and finally the mixed raw materials are put into a granule extruder to granulate to obtain a solid sterilizing product. Material "XS-1".

Embodiment 2

[0036] 33Kg of quaternary ammonium salt (dodecyl dimethyl benzyl ammonium chloride) and 25Kg of polyamine (hexamethylenetetramine) are mixed at about 60°C, and the temperature is raised to 190-210°C at a speed of 10°C / 15min. React for 40-50 minutes, then add 17Kg of guanidine salt (guanidine nitrate) for mixing, then add 25Kg of cetyl alcohol polyoxyethylene ether and other raw materials when the temperature is lowered to 125-130°C, mix for 30 minutes, and finally put the mixed raw materials into the granule extrusion Plastic machine granulation to obtain solid sterilization and disinfection new material "XS-2".

Embodiment 3

[0038] Mix 50Kg of quaternary ammonium salt (benzalkonium bromide) and 20Kg of polyamine (1-6 hexamethylenediamine) at about 60°C, heat up to 190-210°C at a speed of 10°C / 15min, react for 40-50 minutes, and then Add 8Kg of guanidine salt (guanidine hydrochloride) and mix, then add 22Kg of cetyl alcohol polyoxyethylene ether and other raw materials when the temperature is lowered to 125-130°C, mix for 30 minutes, and finally put the mixed raw materials into a granule extruder for granulation to obtain solid sterilization Sterilized new material "XS-3".

Abstract

The invention relates to a novel solid sterilizing and disinfecting material, and preparation and application thereof. The novel sterilizing and disinfecting material is prepared from the following main raw materials: quaternary ammonium salt, polyamine, cetanol polyethylene ether and guanidine salt; the novel sterilizing and disinfecting material can quickly kill all bacteria and viruses in surroundings within a short time by a purely physical method, the whole process is quick, clean and complete, and the purely physical process does not have any toxic or side effect; the novel sterilizing and disinfecting material can be widely applied to the fields of medical and health industry, food packaging and refreshing industry, aquaculture industry, aquarium fish and landscape water treatment, sterilization and disinfection of silkworm breeding utensils and the surroundings, long-range fishing operation, water treatment industry, aerospace and the like; the novel sterilizing and disinfecting material can be produced into many products having significant impacts on human life and production, such as nonwoven fabric, a filter screen, a film, a respirator, a sanitary napkin, underwear, socks, patient clothes, beddings and water pipes with excellent bactericidal performance.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a new solid material for sterilization and disinfection, as well as its preparation and application. Background technique [0002] Bacteria and viruses have seriously threatened people's health since the beginning of history and have taken or are taking countless lives. For this reason, human beings have spent a lot of manpower and material resources to develop many sterilization methods and medicines, but these methods are similar to medicines or their efficacy Single, or the pollution is serious, and there is no medicine and material that can kill bacteria and viruses, so it is necessary to develop a new material for sterilization and disinfection that can kill bacteria and viruses without pollution and has long-lasting functions. A worldwide imperative. [0003] At present, most of the new sterilization and disinfection materials in the world are liquid or gas. ...
