Technical Field
The application relates to the technical field of medical instrument cleaning, in particular to a dust-removing dye paste for medical instruments and a preparation method and application thereof.
Background
Hospitals are a special public place, and the environment must be kept clean and tidy. For the operating room and the instrument decontamination room in the supply center, the sterilizing liquid or the product with specific functions is used for a long time, so that the pollution to different degrees is caused, for example, iodine preparations cause yellow staining of the ground of the operating room, phthalic dicarboxaldehyde causes grey staining of the instrument sterilization groove body, and more serious grey staining causes damage to the mirror body. While the supply center needs to handle a large number of medical instruments every day, phthalic aldehyde is an advantageous choice for handling medical instruments due to its remarkable high efficiency in sterilization.
The intractable phenomenon of gray dyeing also causes deep pain and absolute pain of medical staff, and after a large amount of decontamination work is carried out every day, the device sterilization groove body needs to be immediately protected, so that time is spent, labor cost is wasted unnecessarily, and obvious intractable stains can be left after untimely treatment or improper treatment agent is used.

As preferable: the quaternary ammonium salt surfactant is one or more of tetradecyl trimethyl ammonium chloride, octadecyl amide dimethyl propyl ammonium chloride, dodecyl dimethyl ammonium chloride and dimethyl dioctadecyl ammonium chloride.
By adopting the technical scheme, when the types of the quaternary ammonium salt surfactant are selected within the range, grey dyeing can be effectively removed.
As preferable: the weight ratio of the magnesium metatitanate to the zinc oxide is 1: (0.5-5).
By adopting the technical scheme, when the photosensitive resin and the paste powder are added at the same time, the ash removal capability is better.
As preferable: the organic acid is citric acid or oxalic acid.
As preferable: the particle size of the paste powder is 0.02-20 μm.
By adopting the technical scheme, when the grain size of the paste powder is in the range, grey dyeing can be effectively removed, and the damage to the surface of a subject is small.
In a second aspect, the present application provides a method for preparing a gray-removing dye paste for medical devices, which adopts the following technical scheme: a preparation method of the ash removal dye paste for medical equipment comprises the following preparation steps:
s1, mixing paste powder, calcium phosphate and photosensitive resin, and ball-milling the mixed materials at the rotating speed of 150-350r/min for 2-10h;
s2, heating water to 50-60 ℃, adding a dispersing agent, an organic acid and a surfactant, stirring for 10-20min, adding the mixture obtained in the S1, stirring and mixing for 10-20min, and cooling to obtain the ash removal dye paste.
By adopting the technical scheme, the preparation method has no technical difficulty, has no special requirements on equipment, and is very suitable for large-scale production; by the preparation method, the ash-removing dye paste with excellent performance can be prepared.
In a third aspect, the present application provides an application of a gray-removing dye paste for medical devices, which adopts the following technical scheme:
the application of the ash-removing dye paste for medical appliances can be used for cleaning stains in kitchens and toilets.
In summary, the present application includes at least one of the following beneficial technical effects:

Performance test
Detection method/test method
The preparation of the gray-out paste for medical devices was carried out according to the preparation methods in examples 1 to 11 and comparative examples 1 to 8, and then the detection was carried out according to the following detection methods, the detection results of which are shown in tables 3 and 4.
Stain removal rate: detecting by a detection method in QB/T2117-95, wherein the test piece is a medical instrument sterilization tank body made of the same material, placing the test piece into the tank body, and manually spraying by using a phthalaldehyde disinfectant until obvious grey dyeing phenomenon is generated on the surface of the test piece, wherein the treatment time of each test piece is between 30 days and 50 days;
wherein, the performance index of the ash removal dye paste is based on the performance index of the general water-based metal cleaning agent in QB/T2117-95.
TABLE 3 Performance index of De-Grating pastes of examples 1-11
| Detecting items | Index (I) |
| Appearance of | The paste is uniform, has no caking and no obvious segregation phenomenon |
| Moisture and volatile/% | 35-45 |
| High temperature stability (60+ -2deg.C, 6 h) | The paste is uniform and does not segregate |
| Low temperature stability (-5+ -2deg.C, 24 h) | The paste is uniform, no crystallization is separated out, and no obvious segregation is generated |
As can be seen from Table 3, the ash removal dye paste prepared by the method meets the index requirements of common detergent.
TABLE 4 detection results of the deashing pastes of examples 1-11 and comparative examples 1-8
The ash removal dye paste prepared in the embodiment 1 is used for cleaning kitchen oil stains and toilet stains, the ash removal dye paste is sprayed on the surfaces of the stains and the oil stains, the cleaning is carried out through a rag after the cleaning is carried out for 1min, and then the cleaning cloth is cleaned, the stains or the oil stains are observed after the cleaning is carried out, so that the dirt or the oil stains can be effectively removed, and no oil stains and no stain residues are observed by naked eyes after the cleaning.
As can be seen from the detection data of examples 1-11 and comparative examples 1-8, the ash removal paste prepared by the application can effectively remove ash caused by phthalic dicarboxaldehyde, the removal rate is 95% or more, and the maximum removal rate can reach 98.7%; the ash-removing dye paste has the advantages that ash-removing caused by phthalaldehyde can be accurately removed.
From examples 1 to 3, it can be seen that, in the case of determining the addition amount of the surfactant, the lime-removing dye paste is in a better proportion in the proportion of the rest raw materials, example 2; the detection data of comparative examples 1-5 show that the ash removal paste has better ash removal capability, mainly removes ash by the mutual cooperation among coconut diethanolamide in surfactant, quaternary ammonium salt surfactant, fatty alcohol polyoxyethylene ether and sodium lignosulfonate, and can effectively penetrate into dirt by the cooperation among the raw materials of the surfactant, so as to solve the problem of o-benzene ash caused by protein residue.
As can be seen from the examination data of examples 4 and examples 6 to 8, the addition amount of the surfactant of the present application gradually increased, and the stain removal rate gradually increased, but the increase was small when it reached 14kg or more.
As can be seen from the examination data of examples 7 and examples 9 to 11, the change of the weight ratio of magnesium meta-titanate to zinc oxide in the paste powder or the change of the organic acid to oxalic acid has no substantial influence on the ash removal ability of the ash removal paste. In combination with comparative example 6, the organic acid can promote the graying removal performance; in combination with comparative examples 7 to 8, the photosensitive resin and paste powder were superior in the graying removal ability when added simultaneously.
The foregoing embodiments are all preferred examples of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
