Abstract

A lubricating oil for IC engine and gears is prpared from base oil and compound additives. It features that its moleculae can gradually penetrate into the metallic friction surface to form a complete plasticized protecting film, so eliminating low-temp start abrasion, oil-deficient abrasion and bush burn-off, and smoothing the metal surface.

Description

Oil engine, gear grease

The present invention relates to a kind of lubricating oil, especially for the lubricating oil of oil engine, wheel box.

Lubricating oil is a kind of oil very commonly used in the industry, the used lubricating oil of machine that present oil engine, wheel box etc. turn round at a high speed all has the shortcoming of unstable properties under low temperature or hot conditions, the problem of Chan Shenging is a serious wear when machine startup therefrom, low temperature work down is difficult for forming oil film, oil film cracky when high temperature, machinery heavy wear can produce damage phenomenons such as scuffing of cylinder bore during oil starvation when not having oil.

The objective of the invention is: a kind of lubricating oil of producing by special process is provided; it can form plasticizing dryness protective membrane at friction surface; thereby the not directly contact friction of protection friction surface improves mechanical property, the prolonged mechanical life-span under the various situations of mechanical movement.

The present invention is achieved in that it is formed by configurations such as base oil, recombiners, the proportioning of used material is (by weight percentage): base oil 50～80%, recombiner 5～15%, tetrafluoroethylene 2～8%, suspension tackiness agent 2～10%, anti-wear agent 1～6%, tackifier 4～10%, oxidation inhibitor 0.1～1%, pour point depressant 0.5～1%, foam reducing composition 0.2～0.4%, non-emulsifying agent 0.5～0.7%, detergent-dispersant additive 0.5～2%.

The production technique of lubricating oil is to synthesize through High Temperature High Pressure, vacuum vaporization, pressure versus flow percussion, filtering and impurity removing, dehydration and decolorization:

(1) base oil is transported in the vacuum reaction still of a flow process, heats, be forced into 15kg/cm to 80 ℃～120 ℃ ², base oil is vaporized, when gaseous state reverts to liquid state, carry out vacuum-treat, and, make the convection current percussion on breaker plate of liquid body with the convection current of high-pressure delivery pump delivery cycle, enter second flow path then;

(2) liquid that flow process is obtained is sent in the vacuum reaction still of second flow path, will prepare burden and heat to 120～150 ℃ after being in harmonious proportion evenly, is forced into 15kg/cm ²To its vaporization, repeat the process of a flow process, finish elementary synthetic;

(3) elementary synthetic liquid enters in three flow process reactors, heats to 120～150 ℃, is forced into 15kg/cm ²To its vaporization, repeat the process of second flow path, finish once more synthetic;

(4) synthetic liquid is sent in four flow process filtering and impurity removing synthesizers once more, heats to 120 ℃, is forced into 15kg/cm ²To its vaporization, when reverting to liquid state, gaseous state carries out vacuum-treat; One, vacuum vaporization separating and filtering removal of impurities processing is carried out with the air-flow filter screen in vacuum limit, limit, finishes three times and synthesizes;

(5) three synthetic liquid is sent in five flow processs dehydration synthesizers, heats to 120～160 ℃, is forced into 15kg/cm ²To its vaporization, the separating and dehydrating of vaporizing in vacuum state is handled, and finishes four times and synthesizes;

(6) four synthetic liquid are sent into the decolouring synthesizer of six flow processs, heat to 150 ℃, are forced into 18kg/cm ²To its vaporization, in vacuum state, vaporize and separate the decolouring processing, return to liquid state, finish five times and synthesize;

(7) five times synthetic liquid is sent in the vacuum filling device of seven flow processs, and temperature control is used 3kg/cm at 50～80 ℃ ²The pressure transferpump be transported to the vacuum filling line carry out can, the packing get product.

The present invention compared with prior art, have and in-40 ℃～200 ℃ temperature ranges, normally to use, the metallic surface does not have wearing and tearing substantially, can improve mechanical power 10～20%, fuel-economizing 10～20%, mechanical outward current reduces by 5～20%, mechanical temperature reduces by 10～20%, 2～4 times of prolonged mechanical life-span, lubricating oil, mechanicalness noise reduces by 10～20%, reduces advantages such as pollution emission 5～20%.Because the synthetic lubrication molecule progressively is penetrated into metal friction surface with the expansion of chemi-excitation molecule under High Temperature High Pressure; form intact plasticizing dryness protective membrane; becoming the metallic surface friction rubs mutually into protective membrane; the cold-starting wearing and tearing have been eliminated; oil starvation wearing and tearing in short-term; phenomenon such as scuffing of cylinder bore tile kilning when not having oil, filling simultaneously the metallic surface of micro-rough, accomplish that real " best bright finish " handle.
