Abstract
The present invention is characterized in that the two components of a dimethylsiloxane polymer and an acrylate copolymer are used in the same lubricating oil product; the compounding of the application performance of the two substances enhances the quality of the lubricating oil products, such as internal combustion engine oil, gear oil, hydraulic oil steam turbine oil, etc., and improves the disadvantages of poor foaming resistance or poor air release performance at the time of the single use of the dimethylsiloxane polymer or the acrylate copolymer.
Description
The present invention relates to efficient anti-bubbling agent and application method thereof, specifically, the present invention relates to two component kilfoams, and it is used for the method for oil product dimethylsiloxane polymer (abbreviation silicone oil) and the compound composition of a kind of acrylate copolymer (being called for short last 902); And dimethylsiloxane polymer and a kind of acrylate copolymer solution added respectively in the oil product, as efficient anti-bubbling agent.The complex effect of the application performance by above-mentioned two kinds of kilfoams is to improve I. C. engine oil, gear oil, hydraulic efficiency oil and steam turbine wet goods lubricating oil product quality and to improve when using silicone oil or acrylate copolymer separately anti-bubble property difference or the shortcoming of gas release performance difference.
In order to reduce or eliminate the foaminess of lubricating oil, generally used following three class methods both at home and abroad:
1. use efficient anti-bubbling agent silicone oil and anti-bubble ability and anti-bubble persistence for improving silicone oil, adopted various dispersion addition method, promptly adopt means machinery or solvent cut, equably be scattered in oil product with nano sized particles (particle diameter＜10 μ) silicone oil; Add in the lubricating oil again after perhaps silicone oil being made emulsion with various dispersion agents.
2. with silicone oil and the compound use of low molecular polarity compound (as alcohol, amine, aldehyde, acid etc.), as at U.S. Patent number 2,972,579 and 3,235,498 are disclosed.
3. the development structure is different from acrylate or the methacrylate polymers or the multipolymer of the efficient anti-bubble property of having of silicone oil, and as at U.S. Patent number 3,166,508 are disclosed.
But above the whole bag of tricks is not that the foaming problem of all lubricating oil or gas release performance problem can both finely be solved.For example I. C. engine oil, gear of vehicle wet goods oil product, gene basis oil source variations sometimes, production technique adjustment, operational condition fluctuation and cause the trace change of oil base stock composition; Or changed the surface property of oil product because of the use of multiple additives, so that cause the variation of oil product lathering property, make the existing dimethyl silicone oil kilfoam of independent employing or adopt the polyacrylate kilfoam separately, all be difficult to make the anti-bubble performance of lubricating oil product to get a desired effect.
Other oil products, as hydraulic efficiency oil, turbine oil and lathe wet goods oil product, sometimes the refining depth of gene basis oil is not enough, or because of the adding of some additive, make these oil products when using the non-silicon kilfoam of acrylate type separately or using silicone oil type kilfoam separately, the air release property of lubricating oil product and anti-bubble property are difficult to get a desired effect simultaneously.
Anti-bubble problem or air release property problem when above-mentioned situation occurring in order to solve oil product the invention provides a kind of pair of component efficient anti-bubbling agent, comprise have formula (I) dimethylsiloxane polymer (1) and have the acrylate copolymer (2) of formula (II):

From table-2 as can be known, in the gear oil GL-5 of high-end vehicle, if add silicone oil (1) or acrylate copolymer kilfoam (2) separately, when the anti-bubble property of oil product is defective, then two kinds of kilfoams are used for oil product simultaneously, the anti-bubble of oil product performance just can reach the quality index of regulation.
3. the effect in hydraulic efficiency oil.
In the hydraulic efficiency oil prescription, contain T
705During rust-preventive agent, use 902 kilfoams (2) on the non-silicon separately, the oil product gas release performance is qualified, but anti-bubble property is bad; Use silicone oil kilfoam (1) separately, anti-bubble property is good, but the venting value difference if add the silicone oil of minute quantity in non-silicon kilfoam, then can make anti-bubble property and gas release performance all can reach criterion of acceptability, sees Table-3.

At the high viscosity lathe with the effect in the oil.
Because the high viscosity oil product is responsive especially to the silicone oil kilfoam, even very little consumption, disadvantageous effect to the oil product gas release performance is also very remarkable, at this moment adopt the silicone oil (1) and acrylate copolymer (2) Application of composite of trace, then the gas release performance of oil product and anti-bubble property all will reach the purpose of remarkable improvement, see Table-4.
The Application of composite effect of table 4. kilfoam in the high viscosity oil product

Because silicone oil kilfoam (1) and acrylate copolymer kilfoam (2) differ from one another and advantage, in I. C. engine oil, gear oil and hydraulic pressure wet goods oil manufacture, can be with these two kinds of compound uses of dissimilar kilfoams, to bring into play their outstanding advantages separately, avoid shortcoming separately, improve the anti-bubble property of oil product or improve its purpose to the gas release performance to reach.
As mentioned above, the application method of two component kilfoams can adopt 1 method and 2 methods to make an addition in the oil product, all can reach above-mentioned same effect and purpose.
