Abstract

The present invention relates to a long-acting rust-proofing grease for track bolt. Its ingredients are (wt%) 6-8 of carboxylic sulfonate and organic bentonite each, 2-4 of aluminium distearate, 5-8 of phosphorization-modified silicon dioxide, 0.5-1.5 of binary ehtylene-propylene rubber, 1-3 of 2402 resin, 3-5 of petroleum resin, 0.1-0.3 of dibutyl phthalate, 15-25 of No.24 cylinder oil, and the rest is No.46 machine oil. Said rust-proofing grease has the strong rust-resistance, wear hardness and hydrophobing property, and its drop out point is greater than 180 deg.C and its freezing point is less than 18 deg.C below, so that it can resist high temp. and easy to carry about and easy to construct in winter.

Description

The long-acting anti-embroidery fat of track sieve bolt

The present invention is a kind of anti-embroidery agent, mainly is applicable to the anti-embroidery of track sieve bolt.

As everyone knows, sieve bolt on the track exposes in the car physical environment all the year round, be through wind, Exposure to Sunlight, drench with rain and the draining of train, and steam discharge and other rugged environment are corroding track sieve bolt constantly.The track sieve bolt rustproofing supplies that use mainly are machine oil, butter, mechanical rust preventing grease etc. at present.It is antirust that these only are fit to the indoor long-term antirust and wrapped outdoor short-term of engineering goods.Because of adapting to track sieve bolt open air, its dropping point low (55 ℃) is not exposed to the sun (reaching 60-70 ℃ sometimes), so a little less than this antirust product adhesive power, sticking warm nature is also relatively poor.Also have a kind of hot fat liquoring (180 ℃ of dropping points) in addition though can stand and be exposed to the sun but in construction, need heat, because of the track construction disperses, field work, it is very inconvenient to carry warming-up device.

Purpose of the present invention is made the long-acting rust-proof grease of a kind of suitable track sieve bolt particular surroundings of living in, requires the antirust time long, and adhesive power is strong, and sticking warm nature is good, easy to carry, is easy to construction.

Above-mentioned purpose is achieved in that the ratio of components of this rust preventing grease is: carboxylic-acid sulfonate 6-8%, double stearic acid aluminium 2-4%, phosphatization improved silica 5-8%, organic Peng Run soil 6-8%, ethylene propylene rubber 0.5-1.5%, 2402 resin 1-3%, petroleum resin 3-5%, dibutyl phthalate (DBP) 0.1-0.3%, 24# locomotive oil 15-25%, surplus is the N46# machinery oil.Use above raw material, successively add in the reactor of band stirring, keep higher temperature promptly to can be made into.

Rust-preventing characteristic, wear resistance, the hydrophobicity of track sieve bolt long-acting rust-proof grease made from this prescription are very strong, and its dropping point is greater than 180 ℃, and sticking warm nature is good, is not afraid of high temperature and is exposed to the sun.This rust preventing grease adhesive power is strong, stands rainwater and train draining, deflated wash away.The sticking at normal temperatures scheduling of this rust preventing grease changes little, is easy to carry and constructs.

The present invention goes out following embodiment and realizes: at first 20% 24# locomotive oil and the adding of N46# machinery oil are with in the reactor that stirs, be warming up to about 120 ℃ and keep constant temperature, stir and add 1% ethylene propylene rubber after 30 minutes, stir and add 3% double stearic acid aluminium again after 1 hour, stir and add 2%2402 resins and 4% petroleum resin after one hour again, stir and add 6-8% carboxylic-acid sulfonate after 30 minutes again, stir to tremble after 2 hours synthetic material is poured in the opening saponification still, add organic Peng Run soil of 5-8% phosphoric acid modification silicon-dioxide and 6-8% and 0.2% dibutyl phthalate (DBP) this moment again, at this moment after temperature is reduced to about 85 ℃, grind two times through colloidal mill, the to be cooled packing to normal temperature gets final product.

Claims

Track sieve bolt long-acting rust-proof grease belongs to a kind of rust-preventive agent, and it is characterized in that: ratio of components is; Carboxylic-acid sulfonate 6-8%, double stearic acid aluminium 2-4%, phosphatization improved silica 5-8%, organic Peng Run soil 6-8%, ethylene propylene rubber 0.5-1.5%, 2402 resin 1-3%, dibutyl phthalate (DBP) 3-5%, 24# locomotive oil 15-25%, surplus is the N46# machinery oil.
