Special oil for oil-bath type air cleaner

Abstract

The invention discloses special oil for an oil-bath type air cleaner, which belongs to the field of chemical industry and relates to oil for an air cleaner. The invention aims to provide the special oil for the oil-bath type air cleaner, which can be used all the year round. The special oil for the oil-bath type air cleaner comprises the following materials for preparing the oil in parts by weight: base oil of L-AN32 oil for a total loss system, an alkyl naphthalene pour point depressant, an ethylene-propylene copolymer viscosity index improver (T612), a petroleum sulfonate antirusting agent (T702), a benzotriazole copper corrosion inhibitor (T706) and a methyl silicon oil antifoaming agent (T901). The special oil for the oil-bath type air cleaner consists of the base oil and various additives. The base oil has better low-temperature performance and viscosity-temperature performance and moderate kinematic viscosity. The pour point depressant, the viscosity index improver, the anti-rusting agent, the corrosion inhibitor and the like are selected to serve as the additives. The base oil and the additives are blended into an oil product capable of meeting the operating requirement under the working condition of minus 40 DEG C. The oil product is obviously better than diesel oil in low-temperature performance when temperature is minus 40 DEG C, cannot be frozen, still has higher flowability and viscosity and has a better adsorption and filtration action on dust and the like in mining areas. In summer-high-temperature season (40 DEG C), the oil product is kept at certain viscosity, thus, the oil cannot obviously splash during the vehicle bumpiness process. The oil product has no corrosion on metals, and does not have obvious influences on paint films or the performance of sealing rubber. The oil product has good viscosity-temperature performance and a high viscosity index and can be used all the year round, and the viscosity change is small along with the temperature change. Compared with the diesel oil, the cost is reduced by 40 percent. The oil product is a non-toxic and environmental-friendly product.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to oil for air filters. Background technique [0002] Diesel engine oil is generally used in winter for dump truck oil-bath air filters used in mining areas. The problem of using this oil is that the selected specifications and models are often inappropriate, the low temperature performance of the oil (such as pour point) cannot meet the use requirements, and the filtering effect is not good; the cost of using diesel engine oil is high, and other functions are redundant. [0003] Some car owners use the method of adding No. 10 aviation hydraulic oil to the diesel engine oil. Although it can improve the low temperature performance of the oil, in the cold season, the oil has a high viscosity, poor fluidity, and poor filtration effect, which cannot meet the requirements. Requirements. And the cost is even higher than using diesel oil, which is not a good way. [0004] Some car owners u...
