As domestic patent CN1317372C discloses a kind of proportioning and composition of nano fuel additive agent, this patent is and the immediate technology of this technology, this invention has well solved the lubricity problem of rare earth metal nano particle in fuel oil, but still has much room for improvement for compatibleness problem, the stability problem of stablizer.
[summary of the invention]
The object of the invention is to solve above-mentioned deficiency of the prior art, a kind of formula and preparation method with good compatibleness fuel oil storage stabilizer is provided.
Design for achieving the above object a kind of formula with good compatibleness fuel oil storage stabilizer, described stablizer is comprised of following composition and weight percent: rare earth oxide 0.1 ~ 2%, synergist for fuel oil 10 ~ 40%, rare-earth stearate 1 ~ 15%, naphthenic acid rare earth 1 ~ 15%, di-tert-butylphenol 1 ~ 15%, ditertbutylparacresol 1 ~ 15%, dispersion agent 1 ~ 30%, all the other are hydrogenation white oil, and described rare earth oxide is one or more in the lanthanide metal oxide of particle diameter between 50 ~ 150 nanometers.
Described dispersion agent is one or more in calcium naphthenate, sulfur phosphorization polyisobutylene titanate salt, mono alkenyl succimide.
Described synergist for fuel oil is comprised of according to the weight ratio that accounts for below synergist for fuel oil following composition, and the metal oil dissolubility rare earth compound of 5% calcium and cerium and 95% white oil form.
The ratio that described stablizer is added into fuel oil is 1:5000 ~ 1:2000.
The above-mentioned formula of use is prepared a method for fuel oil storage stabilizer, it is characterized in that described method is comprised of following steps,
A. hydrogenation white oil is added in heating container, while being heated to 60-80 ℃, dispersion agent is added in hydrogenation white oil, stop heating, stir until be uniformly distributed,
B. when hydrogenation white oil temperature is down to room temperature 15-30 ℃, rare-earth stearate and naphthenic acid rare earth are added respectively in hydrogenation white oil, stir until be uniformly distributed,
C. above-mentioned mixed solution is heated to 60-80 ℃, keeps temperature, add respectively rare earth metal powder and RE oxide powder, stir until be uniformly distributed,
D. be heated to 110-130 ℃, add di-tert-butylphenol and ditertbutylparacresol, circulation stirring until be uniformly distributed, keeps this temperature after 2 hours, to stop heating,
E. when naturally cooling to 60-80 ℃, add synergist for fuel oil and hydrogenation white oil, circulation stirring is until be uniformly distributed static 24 hours.
The present invention utilizes the polygamy position bonding performance of rare earth, the surfactivity of nano-powder and the distinctive microcosmic of nano-powder and macro-scale feature, when greatly improving fuel oil stability, the compatibility of other auxiliary agent in enhancing and fuel oil, can be widely used in the modulation of all kinds of fuel oils greatly.
The auxiliary agents such as the rare-earth stearate 1 ~ 15% increasing in the present invention, naphthenic acid rare earth 1 ~ 15%, ditertbutylparacresol 1 ~ 15%, these auxiliary agents are not still for antioxygen and anti-old, under preparation method and proportioning in the technical program, can also further reach the effect that improves compatibleness and fuel oil stability.Yet, only use in the prior art these auxiliary agents can cause with oil product in the chemical reaction of other additive, the phenomenon that cause precipitation, even lost efficacy.
[embodiment]
The present invention's device used is very clearly concerning this professional people.
Component of the present invention and weight percent are as follows:
One or more in the lanthanide metal oxide of RE oxide powder 0.1-2%(granularity between 50-150 nanometer);
The JM-1 type synergist for fuel oil that synergist for fuel oil 10-40%(Shanghai energy collecting Chemical Co., Ltd. produces, because its component is to account for the mixture that the white oil of the calcium of synergist for fuel oil approximately 5% and the metal oil dissolubility rare earth compound of cerium and 95% forms, the dispersion of rare earth nano powder is played to booster action);
Rare-earth stearate 1-15%;
Naphthenic acid rare earth 1-15%;
Di-tert-butylphenol 1-15%;
Ditertbutylparacresol 1-15%;
