Abstract

The invention discloses barium-free antirust grease with thixotropy after dilution. The barium-free antirust grease is characterized by comprising the following raw materials in parts by weight: 13-16 parts of beewax, 10-14 parts of spermaceti wax, 36-41 parts of vaseline, 12-15 parts of burning kerosene, 10-13 parts of 50# machine oil, 3-5 parts of attapulgite, 3-4 parts of asphalt, 2-4 parts of precipitated silicon dioxide, 6-8 parts of petroleum sodium sulfonate, 2-3 parts of high-density polyethylene powder, 2-2.5 parts of sorbitan monooleate and 2.5-4 parts of a protective agent. The precipitated silicon dioxide and other thixotropic agents are added into the formula, the phenomenon that waste is caused because the product is easy to flow when being diluted to be used can be avoided, the addition of the protective agent is matched, a firm protective film can be formed on the metal surface, rust caused by erosion of water and oxygen is avoided, and the barium-free antirust grease has the antibacterial, anticorrosive and ultraviolet radiation-resistant effects. Moreover, the antirust grease disclosed by the invention has barium-free and environment-friendly effects, is wide in application range and is suitable for sealing or machining metal parts, and can be used through multiple ways.

Description

Having after a kind of dilution can be thixotropic without barium rust preventing grease and preparation method thereof

Technical field

The present invention relates to rust protection liquid field, particularly having after a kind of dilution can be thixotropic without barium rust preventing grease and preparation method thereof.

Background technology

For protection metal does not corrode by the corrosive medium in environment, in engineering construction, usually use rust preventing grease that metallic surface and corrosive medium are isolated.Use rust preventing grease to be a kind of more satisfactory, effective anti-corrosion method as temporary protection, there is the advantage of effective, easy to use, with low cost, easy and simple to handle and easy removal.But the slowly-releasing inhibition ingredient of most baric all also exists serious harm to environment and human body, and developed country just progressively substitutes, and American-European countries strictly limits use.

The present invention adopts can diluted formulations; can use with after the kerosene cutback of 10 times amount, can be widely used in anti-corrosion of metal, the present invention with the addition of thixotropic agent precipitated silica etc. in formula; coordinate with protective material; slushing oil not easily trickles, and can form firmly protective membrane in metallic surface, the erosion of anti-sealing and oxygen causes getting rusty; but also there is uvioresistant irradiation; effect of Antimicrobial preservative, efficiently, saves.

Summary of the invention

Having after the object of this invention is to provide a kind of dilution can be thixotropic without barium rust preventing grease and preparation method thereof.

In order to realize object of the present invention, the present invention is by following scheme implementation:

Having after a kind of dilution can be thixotropic without barium rust preventing grease, is made up of the raw material of following weight part: beeswax 13-16, spermaceti 10-14, Vaseline 36-41, illuminating kerosene 12-15, No. 50 machinery oil 10-13, attapulgite 3-5, pitch 3-4, precipitated silica 2-4, petroleum sodium sulfonate 6-8, high density polyethylene(HDPE) powder 2-3, sorbitan monooleate 2-2.5, protective material 2.5-4;

Described protective material is prepared from by the raw material of following weight part: bakelite 10-12, urethane 13-15, ethylene glycol diglycidylether 2-3, butyleneglycol 4.5-6, tween 80 1-2, myristyl benzyl dimethyl ammonium chloride 0.1-0.2, red iron oxide 3-4, nano titanium oxide 2-4, Viscotrol C 5-7, Zinic stearas 2-3, silicon dioxide gel 3-5, sec.-propyl three isophthaloyl titanic acid ester 0.3-0.5; First preparation method adds Viscotrol C, silicon dioxide gel, agitation grinding 50-60 minute by after red iron oxide, nano titanium oxide mixing, forms dispersion; Then by bakelite, urethane, the mixing of sec.-propyl three isophthaloyl titanic acid ester, be heated to 90 DEG C-115 DEG C stirring reaction 2-3 hour, be cooled to 45 DEG C-60 DEG C again, add all the other remaining components except tween 80, myristyl benzyl dimethyl ammonium chloride, stir 30-40 minute with the speed of 400-500 rev/min; Finally be cooled to room temperature, add dispersion and tween 80, myristyl benzyl dimethyl ammonium chloride, stir and obtain protective material.

Having after one dilution of the present invention can be thixotropic without barium rust preventing grease, is made up of following concrete steps:

(1) will add precipitated silica, attapulgite, beeswax, spermaceti in illuminating kerosene, gradation adds Vaseline, fully grinding 2-2.5 hour;

(2) be heated to soften by high density polyethylene(HDPE) powder, then temperature control is at 80 DEG C-100 DEG C, adds barium mahogany sulfonate, pitch, and insulation 60-90 minute, is then cooled to 45 DEG C-55 DEG C, adds sorbitan monooleate, insulation reaction 30-40 minute;

(3) step (1) is mixed with step (2), add protective material, stir 15-30 minute with the speed of 300-350 rev/min; then all the other remaining components are added; be heated to 55 DEG C-65 DEG C, continue to stir 1.5-2 hour, then namely cold going obtain rust preventing grease of the present invention to room temperature.

Excellent effect of the present invention is: the present invention adds the thixotropic agent such as precipitated silica in formula, can prevent product from easily to trickle the waste caused when diluting and using, the interpolation of mating protection agent, firmly protective membrane can be formed in metallic surface, the erosion of anti-sealing and oxygen causes getting rusty, and there is Antimicrobial preservative, effect that uvioresistant is irradiated; The present invention is without barium environmental protection, and product use range is wide, multiple using method, is applicable to metal parts etc. and seals up for safekeeping or process use.
