Problems solved by technology

The traditional wiping and oiling method is very easy to make the joints, shaft joints and other parts of the instrument stick to fiber shavings, causing pollution
In addition, wiping and oiling cannot wipe the parts that cannot be fully opened and the gaps of the shaft joints, resulting in the inflexibility of the shaft joints in these parts, which greatly increases the rust rate of the instrument and shortens the service life of the instrument.

Embodiment 1

[0030] Described spray type lubricating antirust agent, the mass percentage of its each component is composed of:

[0031]

[0032] The base oil is medical mineral oil, the emulsifier is sorbitan fatty acid ester, the co-emulsifier is long-chain fatty acid, the solvent is ethanol, and the propellant is propane.

[0033] Mix the above components, stir evenly, and let it stand for 30 minutes to form a clear and transparent solution. Add the above mixture into a tinplate tank with a spray valve, and fill the tank with 25% propane gas at 0.6 MPa through the valve to obtain a spray-type lubricating rust preventive agent.

Embodiment 2

[0035] Described spray type lubricating antirust agent, the mass percentage of its each component is composed of:

[0036]

[0037] Wherein the base oil is medical mineral oil, the emulsifier is polyoxyethylene sorbitan fatty acid ester (5%) and triethanolamine oleate (5%), the co-emulsifier is a long-chain fatty alcohol, and the solvent is n-propanol, The propellant is n-butane.

[0038] Mix the above components, stir evenly, and let it stand for 30 minutes to form a clear and transparent solution. Add the above mixture into a tinplate tank with a spray valve, and fill the tank with 30% n-butane gas at 0.4 MPa through the valve to obtain a spray-type lubricating rust inhibitor.

Embodiment 3

[0040] Described spray type lubricating antirust agent, the mass percentage of its each component is composed of:

[0041]

[0042] Wherein the base oil is medical mineral oil, the emulsifier is triethanolamine oleate, the co-emulsifier is sodium lauryl sulfate (2%) and sodium dodecylbenzenesulfonate (3%), and the solvent is sec-butanol, The propellant is isobutane.

[0043] Mix the above components, stir evenly, and let it stand for 30 minutes to form a clear and transparent solution. Add the above mixture into a tinplate tank with a spray valve, and fill the tank with 15% isobutane gas at 0.5 MPa through the valve to obtain a spray-type lubricating rust preventive agent.

Abstract

The invention relates to a spray type lubricating antirust agent and a preparation method thereof, and belongs to the technical field of adjuvants for medical apparatus and instruments. The spray type lubricating antirust agent is prepared from the following raw materials in percentage by weight: 10 to 50 percent of basic oil, 10 to 60 percent of an emulsifier, 1 to 10 percent of a co-emulsifier, 2 to 60 percent of a solvent and 10 to 50 percent of a propellant. According to the spray type lubricating antirust agent, the raw materials are environmentally-friendly and readily available; the spray type lubricating antirust agent is high in drying speed, good in lubricating effect and high in water solubility and can be completely punctured by sterilization factors. The invention further provides a simple and feasible preparation method.

Description

technical field [0001] The invention relates to a spray-type lubricating antirust agent and a preparation method thereof, belonging to the technical field of auxiliaries for medical equipment. Background technique [0002] With the continuous development of medical technology, high-tech development such as artificial joint replacement, organ transplantation and valve replacement is developing rapidly, and the wide application of expensive and complex precision instruments, the cleaning, disinfection, lubrication, maintenance and packaging sterilization of surgical instruments are put forward. The requirements are higher, and there are many types of surgical instruments, which are expensive and have different shapes. Oiling is particularly critical to maintain and prolong the service life of the instruments. The working principle of the lubricating antirust agent is to form a protective film on the surface of the medical device that can be penetrated by sterilizing factors, e...
