Abstract
The invention relates to an environment-friendly nondestructive sensitive equipment disinfectant for contaminating toxic and harmful chemical substances, which belongs to the field of novel material development and application. Meanwhile, the disinfectant can eliminate toxic chemical substance pesticides, toxic industrial chemicals and the like which are stained on the surface of sensitive equipment by means of scrubbing, dipping, washing and the like.
Description
Technical Field
The invention relates to a formula and a preparation method of an environment-friendly nondestructive sensitive equipment disinfectant aiming at toxic and harmful chemical substances, belongs to the field of novel material development and application, and is used for eliminating toxic and harmful chemical substance pesticides, toxic and harmful industrial chemicals and the like infected on the surface of sensitive equipment.
Background
The leakage of toxic chemicals (such as pesticides and toxic industrial chemicals) caused by poor management, accidents, sudden natural disasters and the like has become one of the major threats in the field of public safety. As these chemicals leak, the interior and surface of the vehicle facilities, instruments, and the like are contaminated. These contaminated articles must be effectively sterilized to avoid continued damage.
However, some electronic, optical, communication, and digital devices such as smart phones, digital cameras/video cameras, palm computers, various communication devices, etc. are very sensitive to water, and as long as a small amount of water enters the device, the water can cause circuit elements in the device to be short-circuited and burned, thereby causing problems such as loss of stored data and information, incapability of using the device, and damage to the device.
For toxic and harmful chemical substances infected by sensitive equipment, if the equipment is disinfected by adopting a common strong-base and strong-oxidation water-based decontamination solution, the problems of short circuit of a circuit, oxidation and corrosion of a surface coating and internal parts and the like are caused, and the performance and the service life of the sensitive equipment are seriously influenced, namely the traditional water-based disinfection method is not suitable for disinfecting the sensitive equipment.
In the precision electronic industry, inert and non-conductive organic solvents such as Freon, hydrofluorocarbon and the like are adopted for removing pollutants such as oil stains on circuit boards, so that the oil stains on the surfaces can be thoroughly removed, and the performance of electronic circuit boards is well maintained, but the organic solvents are ozone layer depletion substances (ODS) and are about to be thoroughly eliminated.
Hydrofluoroether is a substitute for solvents such as freon and hydrofluorocarbon, which not only retains the ability of solvents such as freon and hydrofluorocarbon to remove oily stains, but is not itself an ozone layer depleting substance.
At present, electronic equipment cleaning agents taking hydrofluoroethers as main components have been reported for many times. A novel cleaning agent composition based on hydrofluoroether and a preparation method thereof (application No. 201710849281.1) report that a cleaning agent prepared by compounding various hydrofluoroethers and auxiliaries has a good cleaning effect on oil stains. A semiconductor surface cleaning agent and a method for producing the same (application No. 201510593289.7) report the use of a cleaning agent containing hydrofluoroether for removing residues, flux, rosin, fingerprints, dust, etc. from the surface of a semiconductor.
However, the above patent focuses on the removal of substances such as oil stains from electronic equipment, and the removal of toxic substances contaminating sensitive equipment is obviously lack of research. In fact, to achieve the removal of toxic substances contaminating sensitive equipment, the solvents required must satisfy the following properties:
1. has good solubility to common toxic substances (organic phosphorus, organic chlorine pesticide, toxic industrial chemicals and the like),
2. has little damage to various materials of the component sensitive equipment, does not influence the normal use of the sensitive equipment after cleaning,
3. low toxicity, low residue, less influence on the health of operators,
4. non-conducting, non-flammable, thermally stable, easily recyclable, environmentally friendly (ODS is zero or near zero).
5. The method can quickly and thoroughly remove the pollutants inside and on the surface of the sensitive equipment by soaking, washing, wiping and the like.
