12The mixing acid of binary acid, binary metallic based grease composition that " on the spot " reaction generates in lubricating base oil and preparation method thereof.
In the past, with the acid of a kind,,, prepared basic metal and alkaline-earth metal mixing soap grease composition as the alkali of lithium and calcium and alkali or sodium and calcium with the alkali of basic metal and alkaline-earth metal as senior hydroxy fatty acid or higher fatty acid.
Prepare such mixing soap grease composition, seek out the high dropping point of alkali metal soap lubricating grease exactly, simultaneously, give lubricating grease certain water resisting property again with alkaling earth metal base.But with the mixing soap grease composition of the alkali preparation of the acid of a kind and two kinds, dropping point is not too high, still can't be suitable for the use of high temperature lubricating.
The soap of the metal of two families can make up for each other's deficiencies and learn from each other, and it is compound that the acid of two kinds makes soap take place easily.Therefore, when seeking the superior grease composition of over-all properties, obviously, composite alkali metal and alkaling earth metal base grease constituent are noticeable.
Recently, the grease composition for preparing of the alkali of the acid of useful two kinds, basic metal and alkaline-earth metal.But the acid of a kind is generally senior hydroxy fatty acid or higher fatty acid, and the acid of another kind is aromatic series monobasic hydroxy acid or binary acid.It still is new adopting the basic metal and the alkaling earth metal base grease constituent of the mixing acid of terephthalic acid or terephthalic acid and binary acid.
The object of the present invention is to provide a kind of new basic metal and alkaling earth metal base grease constituent.The present invention has given full play to the complementary action of soap on performance of the metal of two families, the excellent high-temperature performance that promptly keeps composite alkali metal soap lubricating grease with alkali metal soap, improved the performance of corrosive mediums such as the extreme pressure of grease composition, anti-water and anti-HCl again with alkaling earth metal base, the soap of the metal of two families is compound, also produces certain consonance effect.On some performance, basic metal and alkaling earth metal base grease constituent even be better than the wherein complex soap grease constituent of any one metal.
Grease composition of the present invention contains lubricating base oil and viscosifying agent, and this viscosifying agent is (a) and (b) composite alkali metal and the alkaling earth metal base of two kinds of acid, is from C (a)
