Problems solved by technology

However, the existing anti-corrosion and anti-corrosion functional additives for lubricating grease are not ideal enough, and it is impossible to fully improve the working performance of lubricating grease while anti-corrosion and anti-corrosion
It cannot provide comprehensive protection for mechanical equipment, because in the production process of various types of greases, human beings pay more attention to: greases in light load and high-speed operation applications rely on strong hydrodynamic lubrication, and The current grease production only pays attention to anti-rust, anti-oxidation and anti-wear
Therefore, the overall effectiveness of the grease has been affected to a certain extent.

Embodiment 1

[0010] A rust preventive additive for lubricating grease, consisting of base oil; alkyl succinic acid derivatives; sterically hindered phenol; bissalicylidene propylene diamine; alkyl phosphoric acid esters and salts; lead naphthenate; Isobutylene; composition of random polypropylene. The base oil is a combination of two components of 5 centistokes and 68# of mineral oil and three components of soybean oil in vegetable oil, and the weight ratio of the three components is 1:1:1. The weight percentage of each component is: base oil 28%; alkyl succinic acid derivative 50%; sterically hindered phenol 3%; bissalicylidene propylene diamine 3%; alkyl phosphate ester and salt 6%; Lead alkanoate 3%; borate metal salt 2%; polyisobutylene 3%; random polypropylene 2%. The above base oil; alkyl succinic acid derivatives; sterically hindered phenol; bissalicylidene propylene diamine; alkyl phosphoric acid esters and salts; lead naphthenate; borate metal salts; polyisobutylene; random polyp...

Abstract

The invention relates to a lubricating grease rust-inhibiting additive which comprises the following components in percent by weight: 50-54 percent of alkylsuccinate derivative, 3-5 percent of hindered phenol, 3-5 percent of bis(salicylidene) propanediamine, 6-8 percent of alkyl phosphate salt, 3-5 percent of lead naphthenate, 2-4 percent of metal borates, 3-5 percent of polyisobutene, 2-4 percent of random polypropylene and the balance of base oil. The lubricating grease rust-inhibiting additive has the advantages of simple preparation method, economic and practical preparation scheme and low cost, can ensure that the rust-inhibiting and corrosion-preventing functions of common lubricating grease are greatly improved, improves various comprehensive properties of the lubricating grease while improving the rust-inhibiting and corrosion-preventing functions of the lubricating grease, can prolong the service period of the lubricating grease, and plays a role of protecting various machines and devices.

Description

(1) Technical field [0001] The invention relates to an antirust additive for lubricating grease, in particular to a preparation method and a preparation scheme of the antirust additive for lubricating grease. (2) Background technology: [0002] The current use of grease makes it easier to seal into the bearing because of the semi-solid state of the grease, and also acts as a seal against contamination in wet and dusty environments. Therefore, the use of grease is in great demand. Moreover, the use range of lubricating grease is also very wide, so various grease additives are required to improve the working performance of various greases, so as to meet people's requirements for the use of lubricating grease, so the additives currently used for lubricating grease are more than Lubricating oil additives are also used in large amounts. However, the existing functional additives for anti-corrosion and anti-corrosion of lubricating grease are not ideal, and at the same time of a...
