Description
Technical Field
The invention relates to the fields of daily life air cleaning technology, cultivation disinfection (carrying livestock), aquaculture water body disinfection, agricultural product preservation and the like, in particular to a novel slow-release type gas disinfectant and a preparation method thereof.
Background
The existing disinfectants mainly comprise the following types, namely the traditional halogen disinfectants: (1) the traditional chlorine preparation has strong bactericidal effect on bacteria, spores, viruses and fungi, but has short duration of drug effect, difficult long-term storage of the drugs, strong irritation and corrosiveness, and serious damage to the environment after long-term use. (2) Iodine preparation belongs to a middle-effect disinfectant, and dilute solution of the iodine preparation has low toxicity and no corrosiveness, but is unstable, needs to be prepared at present and is generally used for disinfecting hands and surgical skin. (3) The bromine preparation has the bactericidal effect similar to that of chlorine preparation, and has high algae eliminating performance and high cost.
The phenol type middle-effect disinfectant is easy to be influenced by alkaline organic substances due to low pH value, pollutes the environment, has pungent smell (irritative to mucous membrane systems of human bodies and livestock organisms), has smell detention property, has strong toxicity to human bodies and livestock, is generally only used for disinfecting livestock and poultry empty houses, is not suitable for disinfecting during breeding, and has poor sterilizing effect.
Alcohols belong to middle-effect disinfectants, are volatile, have small irritation to skin and mucous membrane, and are commonly used for disinfecting hands, skin and the like.
The oxidant is mainly used for environmental disinfection, such as disinfection of livestock and poultry houses, feeding troughs, tools, vehicles, floors and walls, particularly has good sterilization effect in low-temperature environment, and is selected as a good disinfectant for cold storage. The disinfectant has no residual toxicity on the articles after disinfection, but has unstable chemical properties, and can be prepared for use at present, and because the disinfectant has strong oxidizing property, the disinfectant can stimulate and damage skin mucous membranes and corrode articles at high concentration, and the disinfectant can powerfully damage eyes, respiratory mucous membranes and environment of human and animals after long-term use.
Surfactants have the characteristics of stability, small side effect and the like, but are ineffective to non-membrane viruses (such as foot-and-mouth disease viruses and vesicular disease viruses), belong to low-efficiency disinfectants and cannot be used for disinfection when epidemic diseases are epidemic.
With the continuous deepening of the global economy integration process, the international trade is increasingly active, and the goods circulation and the personnel traffic scale are unprecedented, so that epidemic diseases outbreaked in different regions of the world invade China. Highly pathogenic epidemic diseases (such as African swine fever, avian influenza and the like) cause destructive attack on the breeding industry, and some diseases directly threaten the life safety of people (such as SAS virus, Ebola virus and the like). Because the sudden virulent epidemic diseases lack effective medicines and vaccines, the epidemic situation can be prevented and controlled only by cutting off a transmission path. Therefore, when a serious epidemic comes, a high-efficiency, broad-spectrum and long-lasting disinfection product is particularly important. However, most of traditional disinfection products are of a spray contact type, the duration time is short, and the biological prevention and control effect on the viral pathogenic agents horizontally spread in the air is difficult to control. Especially in modern pigpen poultry houses, the intensive cultivation must be well ventilated. Air circulation improves the environment while increasing the risk of entry of horizontally transmitted viruses. This is well documented by the outbreak of African swine fever in this year. The frequent occurrence of major epidemic situation forces us to develop a novel disinfection product capable of continuously disinfecting livestock and poultry, so as to break the situation of pallor and weakness before the major epidemic situation.
Therefore, a novel slow-release type gas disinfectant and a preparation method thereof are indispensable.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: (1) the disinfection products circulating in the current market are single in variety and seriously aged, the traditional disinfection products mainly disinfect the environment in a spraying mode, the operation is complex, dead corners are easy to generate, and the disinfection is not thorough;
(2) has corrosivity, strong irritation and high toxicity to metal, has strong irritation to skin and respiratory tract of human and livestock, and cannot be used for disinfection of animals. Part of products have potential safety hazards to human health;
(3) the large-part disinfection product belongs to the contact surface disinfection, and has short action time effect, and cannot form a continuous and effective three-dimensional control and elimination system.
(4) The effective acting time of the disinfection cannot be judged, the disinfection operation cannot be carried out in time, and the risk of biosafety is induced.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a novel slow-release gas disinfectant and a preparation method thereof comprise the following raw materials in percentage by mass: 30-55% of solid acid, 30-45% of sodium chlorite, 15-25% of slow release agent and 2-15% of filling agent.
Compared with the prior art, the invention has the advantages that: (1) the use is convenient, and the use operation can be finished by tearing and hanging the film;
(2) the lasting time is long, the disinfection is carried out continuously for 24 hours, and the drug effect can last for 7 to 15 days;
(3) high-efficiency sterilization, and 1 bag can be hung per 100 cubic meters to effectively kill bacteria, fungi, viruses, mycoplasma and the like;
(4) does not cause 'three causes', namely carcinogenesis, teratogenesis and mutagenesis;
(5) can realize the disinfection of the belt animals;
(6) the oxygen increasing and deodorization can be realized, the effect can be realized after 2 hours after the disinfectant is used, and whether the disinfectant is continuously effective or not can be judged according to the change of odor in the environment;
(7) the metal equipment is not corroded when the device is correctly operated and used;
(8) the sterilization is thorough, no dead angle is left, the epidemic situation horizontal propagation chain can be effectively cut off, and an epidemic situation protective wall is constructed;
as an improvement, the material comprises the following raw materials in percentage by mass: 35-45% of solid acid, 30-40% of sodium chlorite, 18-25% of slow release agent and 4-10% of filling agent.
