Embodiment 1

[0017] Example 1: The formulation described in the following formulation table was used.

[0018] serial number

[0019] The preparation method of Example 1 is as follows: firstly add pure water into the container, add polyvinylpyrrolidone as a solubilizer, stir and dissolve, then add sodium dodecylbenzenesulfonate and sodium carbonate in sequence, and heat to 30°C in a water bath. The reaction was stirred for about 1 hour. Then add methyl silicone oil, after it is completely dissolved, add triazine fungicide and iminodisuccinate into it, mix evenly, raise the temperature to 35°C, and stir for 6-8 hours to prepare. When feeding, one raw material is dissolved and another is added, and the stirring speed is 170±5r / min.

Embodiment 2

[0020] Example 2: The formulation described in the following formulation table was used.

[0021] serial number

[0022] The preparation method of Example 2 is as follows: first add pure water into the container, add the solubilizing agent polyvinylpyrrolidone, and heat to 30° C. in a water bath. After stirring and dissolving, add sodium dodecylbenzenesulfonate, sodium carbonate, methyl silicone oil, triazine fungicides and iminodisuccinate in sequence, mix well, heat up to 40°C, and stir for 6-8 hours to prepare have to. When adding materials, one kind of raw material is dissolved and heated for one hour, and then the other is added, and the stirring speed is 170±5r / min.

Abstract

The invention discloses cleanout fluid applicable to cleaning of clinical laboratory instruments. The cleanout fluid is composed of, by mass, 81-90% of water, 2-4% of a surface active agent, 2-5% of an inorganic auxiliary agent, 1-2% of a solubilizing agent, 1-2% of lubrication rust inhibitor, 0.5-1% of a sterilizing agent and 2-5% of a green chelating agent. The preparation method of the cleanout fluid includes the steps that firstly, pure water is added into a container, then the surface active agent, the inorganic auxiliary agent, the solubilizing agent, the lubrication rust inhibitor, the sterilizing agent and the green chelating agent are sequentially added, the mixture is mixed and stirred to be uniform, and the cleanout fluid is obtained. According to the cleanout fluid, due to the fact that the added iminodisuccinic acid is a brand-new green chelating agent, the cleanout fluid has biodegradability and is safe and environmentally friendly; due to the fact that a compounded mixed surfactant system of the surface active agent sodium dodecyl benzene sulfonate, the inorganic auxiliary agent and the solubilizing agent is added, the cleanout fluid has good oil stain removal capacity and is low in foam output and easy to clean; due to the fact that rust prevention brightener methyl silicone oil is added, the cleanout fluid achieves rust prevention, maintenance and brightening effects on the instruments.

Description

technical field [0001] The invention relates to the technical field of medical detergents, in particular to a cleaning solution suitable for cleaning laboratory instruments and a preparation method thereof. Background technique [0002] Medical instruments in the laboratory are easily contaminated by blood, pus, protein, fat, etc. during use. After use, the instruments must be cleaned or other surface treatment before subsequent disinfection and sterilization. Traditional acidic or neutral cleaning agents are significantly less effective at removing pollutants than alkaline cleaning agents. However, due to the high pH value and strong alkalinity of alkaline cleaning agents, they are more harmful and corrosive to equipment, and the chelating agents used in traditional alkaline cleaning solutions are mostly NTA, EDTA, STPP, etc. Poor degradability, and can lead to pollution problems such as eutrophication of rivers. At the same time, the traditional alkaline cleaning agent a...
