Embodiment 1

[0052] The present invention provides a heavy metal-free rust preventive oil, which comprises the components according to the weight percentages of Example 1 in Table 1 above.

[0053] 1. Preparation of organosilicon-modified vegetable oil

[0054] The preparation method of organosilicon modified vegetable oil comprises the steps:

[0055] (1) Add 100 parts of vegetable oil by mass into the reactor, then gradually add 25 parts of potassium hydroxide methanol solution with a mass concentration of 8%, then carry out transesterification at a temperature of 70° C. for 2 h, wash to Neutral, dehydrated and dried to obtain fatty acid methyl esters;

[0056] (2) Add the mixture of 120 parts of acetic acid and the strong acidic cation exchange resin catalyst to 100 mass fractions of fatty acid methyl esters obtained in the step (1) at a temperature of 60°C, then gradually add hydrogen peroxide solution, wherein H O and acetic acid The mol ratio is 1.2:1, insulation 4h carries out epo...

Embodiment 2-10

[0069] Each of the antirust oils without heavy metals in Examples 2-10 includes the components in the weight percent of Examples 2-10 in the above table 1, and the preparation method of the organosilicon-modified vegetable oil used, the modified thiadiazole The preparation method and the preparation method of the heavy metal-free antirust oil are consistent with Example 1.

[0070] The methods, procedures, and evaluations of the physical properties of the heavy metal-free rust preventive oils of Examples 1-10 were carried out in accordance with standards such as GB / T510, SH / T0215, and GB / T2361. The results are shown in Table 2.

Abstract

The invention discloses anti-rust oil free of heavy metals. The anti-rust oil is prepared from, by weight, 1%-15% of a first anti-rust agent, 1%-10% of a second anti-rust agent, 5%-15% of a film-forming agent, 0.1%-5% of an antioxidant, 0.1%-5% of a preservative, 0.01%-2% of a defoaming agent, 0.01%-2% of essence and the balance modified vegetable oil. Components of the anti-rust oil do not contain heavy metals, the modified vegetable oil replaces mineral oil to serve as base oil, the modified vegetable oil is biodegradable and environment-friendly, the modified vegetable oil is not easy to oxidize, the antirust oil is good in stability and long in service life, and the first anti-rust agent and the second anti-rust agent have a synergistic effect, so that the antirust performance is good.

Description

technical field [0001] The invention relates to the technical field of antirust oil, in particular to a green and environment-friendly modified plant antirust oil without heavy metals. Background technique [0002] Existing antirust oils generally contain mineral oil and heavy metals. In recent years, due to various reasons, waste anti-rust oil has entered the natural environment, so the pollution of anti-rust oil and environmental health issues have gradually attracted attention. The development of environmentally friendly anti-rust oil has become a global consensus. [0003] Under the premise of increasing world oil consumption and decreasing reserves, people are prompted to look for mineral oil substitutes to produce anti-rust oil. Utilizing vegetable oil to make antirust oil has become people's choice. Compared with mineral oil, vegetable oil has better biodegradability and is a green and environmentally friendly anti-rust oil. However, vegetable oil itself has some d...
