Metal bearing water-based cleaning agent and preparation method and application thereof

Abstract

The invention discloses a metal bearing water-based cleaning agent and a preparation method and application thereof. The cleaning agent comprises the following components in percentage by mass: 2 to 8 percent of fatty alcohol polyoxyethylene ether, 2 to 8 percent of alkylphenol polyoxyethylene ether, 3 to 10 percent of fatty acid alkanolamide, 5 to 25 percent of triethanolamine oleate, 10 to 22 percent of triethanolamine, 5 to 18 percent of monoethanolamine, 0.5 to 3 percent of alkyl sodium sulfonate, 0.01 to 0.5 percent of benzotriazole, 1 to 2 percent of disodium ethylene diaminetetraacetate and 3.5 to 71.49 percent of water. During use, the cleaning agent is prepared into 2 to 10 percent working solution, and a bearing part is ultrasonically cleaned, rinsed, subjected to spray washing and dried to meet the cleaning degree standard and the finished product vibration value standard. The product is environment-friendly, does not influence a bearing material, is prepared from readily available raw materials, has low cost, can replace the conventional cleaning gasoline and kerosene, reduces the potential safety hazard, avoids environmental pollution, and saves energy.

Description

[0001] technical field [0002] The invention relates to a metal cleaning agent, in particular to a metal bearing water-based cleaning agent and its preparation method and application. Background technique [0003] As a precision component, the bearing has high requirements on its vibration value and noise. The precision of the raceway of the bearing ring is extremely high. Even tiny impurities left in the raceway will seriously affect the vibration and noise of the bearing. The workmanship is very demanding. Especially for the finished bearing after assembly, since the cage and rolling elements have been assembled, the ring channel is closed in the bearing cavity, and the channel is not easy to clean. Bearing cages and rolling elements, so there are strict requirements for the cleaning medium of finished bearings. [0004] For the cleaning of finished bearings after assembly, kerosene or gasoline medium is still used for cleaning in the bearing industry. Kerosene an...

Problems solved by technology

Although these chemical raw materials are easily soluble in water, sodium carbonate will react with calcium and magnesium ions in water to form precipitates, which will reduce the cleaning effect; and phosphate, as a water softener, will cause eutrophication of water quality after discharge, pollute the environment, and are more irritating. Strong; sodium nitrite remains on the surface of parts after the water volatilizes to form solid crystals, which is difficult to remove

Since these components will produce different degree
