Detailed Description
The invention will be further elucidated with reference to the embodiments, some of which are described briefly below. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the description is to be regarded as illustrative in nature and not as restrictive. The analytical test methods involved in the present invention are shown in Table 1.
TABLE 1 analytical test methods referred to in the present invention
The amount of naphthenic base oil
In the invention, the dosage of the naphthenic base oil is not particularly limited, and the dosage of the naphthenic base oil is preferably 6-30% by mass percent of the total mass of the process oil; if the using amount is less than 6%, the using amount is too low, so that the problems of high product viscosity, reduced cleaning performance, poor additive dissolution, turbidity and even precipitation of oil products and the like can be caused; if the amount is more than 30%, the amount is too high, which causes the problems of low product viscosity, insufficient lubrication performance, too large oil viscosity change under high and low temperature working conditions, and the like, and has no other benefits.
The usage amount of clay refined mineral oil
In the invention, the amount of the clay refined mineral oil is not particularly limited, and is usually about 33-80% by mass of the total process oil; if the amount is less than 33%, the use amount is too low, which causes the viscosity-temperature performance of the product to be poor, thereby causing insufficient lubricating performance; if the amount is more than 80%, the amount is too high, resulting in a high product viscosity, failure to achieve timely rinsing of the shaving powder, and no other benefits.
The amount of saturated polyol ester used
In the present invention, the amount of the saturated polyol ester is not particularly limited, and is preferably 10 to 20% by mass of the total process oil; if the dosage is less than 10%, the dosage is too low, which causes the reduction of the adsorption film forming capability of the product; if the amount is more than 20%, the amount is too high, which may cause the machine tool to be difficult to clean, and also may increase the product cost greatly without other benefits.
TABLE 2 physical and chemical comparison data of saturated polyol ester and rapeseed oil
As can be seen from the main physicochemical comparison data of the saturated polyol ester and the rapeseed oil given in Table 1, the iodine value of the saturated polyol ester is much smaller than that of the rapeseed oil, so that the saturated polyol ester has better oxidation resistance, higher saponification value and better lubricating property.
The amount of chlorine-containing additive
In the invention, the dosage of the chlorine-containing additive is not particularly limited, and is preferably 1-10% by mass of the total process oil; if the dosage is less than 1%, the dosage is too low, which causes insufficient ferric chloride film forming reaction of the product under the working condition of 200-500 ℃; if the amount is more than 10%, the amount is too high, which causes a significant increase in the viscosity of the product to adhere to the work piece and is not beneficial.
The amount of sulfur-containing additive
In the invention, the amount of the sulfur-containing additive is not particularly limited, and is preferably 2-10% by mass of the total process oil; if the using amount is less than 2%, the using amount is too low, so that the film forming reaction of the iron sulfide is insufficient under the high-temperature working condition of the product at the temperature of over 500 ℃; if the amount is more than 10%, the amount is too high, which results in a heavy appearance and odor of the product, and also increases the cost greatly without other benefits.
The amount of synthetic calcium sulfonate used
In the invention, the amount of the synthetic calcium sulfonate is not particularly limited, and is preferably 1-5% by mass of the total process oil; if the dosage is less than 1%, the dosage is too low, so that the product has insufficient antirust and dispersing properties; if the amount is more than 5%, the amount is too high, which results in a significant increase in product cost without other benefits.
The amount of antioxidant used
In the invention, the amount of the antioxidant is not particularly limited, and is preferably 0.1-0.5% by mass of the total mass of the process oil; if the dosage is less than 0.1%, the dosage is too low, so that the product is insufficient in oxidation resistance and goes bad; if the amount is more than 0.5%, the amount is too high, resulting in an increase in product cost without other benefits.
The amount of corrosion inhibitor used
In the invention, the dosage of the corrosion inhibition inhibitor is not particularly limited, and is preferably 0.05-0.1% by weight of the total mass percentage of the process oil; if the dosage is less than 0.05 percent, the dosage is too low, and the corrosion of a processed workpiece can be caused; if the amount is more than 0.1%, the amount is too high, which results in a significant increase in product cost without other benefits.
The dosage of the antifoaming agent
In the present invention, the amount of the antifoaming agent is not particularly limited, and is preferably 5 to 30 mg/kg; if the dosage is less than 5mg/kg, the dosage is too low, so that the product foams and overflows out of the liquid pool; if the amount is more than 30mg/kg, the amount is too high, which causes an increase in cost and no other advantage.

Comparative example 1
The inventors purchased a typical gear-shaving oil product on the market and performed the relevant physical and chemical performance tests, and the results are shown in table 9.
TABLE 9 comparison of the physicochemical and performance properties of a typical product of the invention with those of the market
As can be seen from the performance data given in tables 3-8, the barium-free special process oil for gear shaving processing provided by the invention has excellent extreme pressure, oxidation resistance and other performances, and use tests prove that the barium-free special process oil meets the requirements of the gear shaving processing process, has the characteristics of good lubrication, extreme pressure, cleaning, oxidation resistance and the like, and simultaneously prolongs the service life of a cutter.
It can be seen from table 9 that the process oil composition in example 2 of the present invention has various performance indexes higher than those of domestic product a, and the product does not contain barium, and the processed work piece is allowed to be exported.
