Problems solved by technology

CN 91103460 proposed a preparation method of phosphorothioate, CN 98803628 proposed a sulfur-containing borate anti-wear agent, and US 5482521 reported a nitrogen-containing heterocyclic structure reacted with carboxylic acids and amine compounds. The prepared multi-effect anti-wear additives have anti-oxidation properties, but the anti-wear properties are not enough. They all need to be compounded with sulfur-containing extreme pressure agents to have better extreme pressure and anti-wear properties
The extreme pressure and antiwear agents mentioned above are not suitable for lubricating oil antiwear additives in the working conditions of automatic transmission fluid.

example 1

[0028] This example is the preparation of automatic transmission fluid base fluid (without antiwear agent).

[0029] 5% by weight of polymethacrylate viscosity index improver, 4% by weight of succinimide ashless dispersant, 0.08% by weight of metal deactivator, 0.08% by weight of rust inhibitor, 0.35% by weight of metal detergent, 0.2% by weight % friction modifier, 0.5% by weight of antioxidant, 0.03% by weight of antifoaming agent and the balance of hydrogenated base oil 100N are mixed, and stirred at 70-80°C for 30-40 minutes.

example 2

[0031] Take 195g of di-n-butyl phosphite (trade name T304), add 150g of ethoxylated tallow amine (Ethomeen T-12, produced by Akzo Nobel Chemical Company), stir at 80±5°C for 1h, and the resulting light yellow and clear Liquid is antiwear additive C 1 .

[0032] Will C 1 Add 0.5% by weight to the automatic transmission fluid base fluid of Example 1 to obtain an automatic transmission fluid oil product, which was evaluated by a Falex testing machine. The results are shown in Table 1.

example 3

[0034] Preparation of phosphate amine salts. Add 300g ethoxylated tallow amine (Ethomeen T-12, produced by Akzo Nobel Chemical Company), all the other are with example 2, and the light yellow clear liquid of gained is antiwear additive C 2 .

[0035] Will C 2 Add 0.2% by weight to the automatic transmission fluid base fluid of Example 1, and perform Falex testing machine evaluation. The results are shown in Table 1.

Abstract

The invention provides an organic phosphate amine salt that has a novel structure represented as the following formula, or the organic phosphate amine salt is produced by hydrocarbonyl organic phosphate or hydrocarbonyl phosphorite reacting with ethoxylation alkylamine at 60-100 DEG C. The invention also provides the application method of the above-mentioned organic phosphate amine salt in automatic transmission fluid.

Description

technical field [0001] The invention relates to phosphate ester amine salt, its preparation method and its application method in automatic transmission fluid. Background technique [0002] Phosphorus-containing anti-wear additives widely used at present include di-n-butyl phosphite (T304), nitrogen-containing derivatives of sulfuric acid phosphoric acid (T305), tricresyl phosphate (T306), thiophosphoric acid complex ester amine salt (T307), etc. Although T304 has strong chemical activity, it has poor thermal stability, and at the same time, it has great corrosion and rust to metal; other antiwear agents have insufficient antiwear performance. The use of sulfurized isobutylene (T321), dibenzyl disulfide (T322) and other sulfur-containing extreme pressure anti-wear additives will cause serious corrosion of metals, and have a greater impact on the friction coefficient of the friction pair during use. ZL 95106742.7 proposes an extreme pressure antiwear agent composition, which ...
