Abstract
The invention relates to an extreme pressure additive special for lubricating grease. The additive is basically characterized by comprising the following components by weight percent: 42-46% of chlorinated paraffin; 5-6% of sterically hindered phenol; 4-6% of sulfanilic acid; 3-5% of bis(salicylidene) propanediamine; 6-8% of calcium phosphate; 6-8% of polyisobutene; 8-10% of alkyl phosphate ester and salt; and the balance base oil. The preparation method of the extreme pressure additive is characterized by simplicity and practicability, strong practicality, and low cost. The extreme pressure additive of the invention can substantially improve the extreme pressure performance of lubricating grease, and can improve the comprehensive performance of lubricating grease under the premise of enhanced extreme pressure performance of lubricating grease.
Description
(1) technical field
The present invention relates to a kind of grease additive, the preparation scheme and the method for manufacture of the special-purpose extreme-pressure additive of particularly a kind of railway grease.
(2) background technology:
Because the semi-solid denseness of railway grease, they have some advantages that surpass lubricating oil, and railway grease is sealed in the bearing than lubricating oil more easily, and railway grease does not need the recycle system; And railway grease can be taken on the effect of sealing again under moist and the environment that dust is arranged, resist extraneous contamination.But can not effectively stop the equipment of metal to metal contact having high-load more and oil film; And in mobile equipment and the industrial bearing, accomplish the solution of the problems referred to above with regard to the extreme-pressure additive that requires to have higher extreme pressure effect, current solubility extreme-pressure additive effect is single; Can not be when accomplishing the extreme pressure use; Possess more comprehensively effect, even if can solve the railway grease solubility extreme-pressure additive of single extreme pressure effect, market value is also relatively more expensive.And complicated process of preparation, versatility is poor, and effect is single.
(3) summary of the invention
The objective of the invention is to solve the problem that exists in the above-mentioned technology; Provide a kind of high-quality; Multi-usage, low price, preparation is simple; The extreme pressure property of railway grease is improved greatly and when the extreme pressure property of railway grease improves greatly, a kind of railway grease solubility extreme-pressure additive of railway grease over-all properties can be improved.
Technical scheme of the present invention:
The special-purpose extreme-pressure additive of a kind of railway grease, essential characteristic is: by base oil; Clorafin; Sterically hindered phenol; Sulphur amine; Two salicylidene tn; Calcium phosphate; Polyisobutene, phosphorous acid esters of alkyl and salt are formed.The weight percent of each component is: clorafin 42-46%; Sterically hindered phenol 5-6%; Sulfanilic acid 4-6%; Two salicylidene tn 3-5%; Calcium phosphate 6-8%; Polyisobutene 6-8%; Phosphorous acid esters of alkyl and salt 8-10%; Surplus is a base oil.
The special-purpose extreme-pressure additive of a kind of railway grease, essential characteristic is: base oil is the 150BS of MO, 5 centistokes, 10 centistokes, any one component and vegetables oil VT 18, any one component of rapeseed oil makes up, the weight quota of two kinds of components is 2: 1.
The special-purpose extreme-pressure additive of a kind of railway grease, essential characteristic is: with base oil; Clorafin; Sterically hindered phenol; Sulfanilic acid; Two salicylidene tn; Calcium phosphate; Polyisobutene; Phosphorous acid esters of alkyl and salt mix, heat and controlled temperature between 55-60 ℃, stirred 120-180 minute, promptly go out product.
Advantage of the present invention: this method is simple, and is practical, and cost is low, and the extreme pressure property of railway grease is improved greatly, and under the prerequisite that the extreme pressure property of railway grease improves, can improve the over-all properties of railway grease.
(4) embodiment
