Problems solved by technology

The application of silicone oil and grease on brake valves of rail transit locomotives is very mature and extensive, but the effect of cleaning silicone oil and grease on brake valves on a fully automatic cleaning line is not good. Ultrasonic cleaning or spray cleaning combined with ultrasonic cleaning The brake valve also requires manual secondary cleaning to meet the cleanliness requirements before installation. During the cleaning process, the cast iron, aluminum alloy, copper alloy and other materials on the brake valve cannot be corroded. After cleaning, the brake valve should have short-term protective effect
At present, most silicone oil and grease cleaners use phosphate as a builder, sodium nitrite as a rust inhibitor, nonylphenol polyoxyethylene ether, etc. as a surfactant, or use isopropanol, ethanol, etc. , petroleum ether, short-chain alcohol ethers, chlorinated hydrocarbons, acetone or hydrocarbon solvents and other organic solvents are used as cleaning agents. These cleaning agents have safety hazards such as high toxicity, flammability and explosion, and are facing elimination.

Abstract

The invention relates to a neutral silicone oil and silicone grease cleaning agent, which comprises the following components and parts by weight: 0.5-2.0 parts of a builder; 0.5-2.0 parts of a complexing agent; 0.2-0.8 parts of a penetrating agent; and a corrosion inhibitor for copper materials 0.2-1.0 parts; aluminum corrosion inhibitor 0.2-2.0 parts; steel rust inhibitor 0.2-6.0 parts; solubilizer 0.2-2.0 parts; nonionic surfactant 1.0-20.0 parts; mixed surfactant 0.0-20.0 parts ; The rest add water to 100 parts. The action mechanism of this cleaning agent is simple and scientific. Through the synergistic effect of each cleaning component, it can penetrate, emulsify and peel off silicone oil and grease dirt. The metal surface has a protective effect, so that the cleaning and protection have the best effect. This agent is safe, environmentally friendly, non-toxic, does not contain phosphorus, nonylphenol, heavy metals, VOC substances, etc., and has a wide range of raw materials, easy access, and low cost. Suitable for mass production.
