Abstract

The invention discloses anti-rust oil for automobile parts and a preparation method thereof. The anti-rust oil comprises the components of liquid paraffin 300#, sorbitan monooleate, a film-forming agent, a silane coupling agent KH550, an antioxidant DLTP (dilauryl thiodipropionate), glycerol, nano-ceramic powder, methyl ethyl ketone, polydimethylsiloxane, 2,6-butylated hydroxytoluene and dibutyl phthalate. The anti-rust oil prepared by the preparation method is good in adhesive force on metal surface, fast to dry, good in salt spray resistance, environment-friendly and free of pollution. The liquid paraffin 300# is adopted as the base oil; and the film-forming agent is added. Thus, the film-forming speed is fast; the surface of the anti-rust oil is not easily oxidized; the appearance of a work-piece is not easily affected; and the overall performance is good. The anti-rust oil is simple in preparation method, low in cost and suitable for large-scale production.

Description

A kind of slushing oil for automobile component and preparation method thereof

Technical field

The present invention relates to a kind of rush-resisting material, be specifically related to a kind of slushing oil for automobile component and preparation method thereof.

Background technology

Metallic corrosion is to make one of principal mode of fastening piece destruction; can cause very big loss to automobile, motorcycle and various vehicle, machinery; according to statistics; it is annual because the direct economic loss that metallic corrosion causes accounts for the 2-4% of total value of production in national economy; for avoiding corrosion, reducing the loss; people have adopted various methods, protect metal fastenings with antirust grease, are one of present modal means of defences.

Summary of the invention

The object of the present invention is to provide a kind of slushing oil for automobile component and preparation method thereof.

The present invention adopts following technical scheme:

The slushing oil that is used for automobile component, the weight part of its constitutive material is: whiteruss 300# 73-78, the smooth monoleate 2.5-3.5 of sorb, membrane-forming agent 5.0-7.0, silane coupling agent KH550 5.0-6.5, anti-oxidant DLTP 1.0-1.2, glycerol 4.0-5.5, nano-ceramic powder 1.0-2.0, methylethylketone 8.0-9.0, polydimethylsiloxane 7.0-9.0,2,6-ditertbutylparacresol 10-12 and dibutyl phthalate 12-14.

The slushing oil that is used for automobile component, the weight part of its constitutive material is: whiteruss 300# 75, the smooth monoleate 3.0 of sorb, membrane-forming agent 6.0, silane coupling agent KH550 5.8, anti-oxidant DLTP 1.1, glycerol 4.8, nano-ceramic powder 1.5, methylethylketone 8.5, polydimethylsiloxane 8.0,2,6-ditertbutylparacresol 11 and dibutyl phthalate 13.

Be used for the preparation method of the slushing oil of automobile component, may further comprise the steps:

(1) measures whiteruss 300# by the weight part of constitutive material, add heated and stirred in the reactor, add 2,6-ditertbutylparacresol during to 115-135 ℃, reaction 20-25min;

(2) in step (1), add membrane-forming agent, anti-oxidant DLTP and methylethylketone, continue to stir, be cooled to 28-32 ℃;

(3) weight part by constitutive material adds other constitutive material in step (2), and continuation gets product after stirring the 2.0-3.5h filtration.

The preparation method of described membrane-forming agent is as follows:

(1) at first 18-22 part methylethylketone, 3.5-4.5 part dimethylbenzene, 2.0-3.0 part ethylene glycol diglycidylether, 8-12 part E-12 Resins, epoxy are mixed in the adding reactor, reaction is 2-3 hour under 70-110 ℃ of temperature;

(2) add 15-18 part MALEIC ANHYDRIDE, 1.3-1.5 part 2,6 ditertbutylparacresols, 1-2 part vinylbenzene, 1.5-1.8 part linking agent TAIC in the reactor of step (1), mix, reaction is 3-5 hour under 50-80 ℃ of temperature condition, namely.

Beneficial effect of the present invention:

Slushing oil, the fast drying good at metallic surface sticking power of the present invention's preparation, salt spray resistance is good, and is environment friendly and pollution-free, and adopting whiteruss 300# is base oil, and added membrane-forming agent, film forming speed is fast, and the slushing oil surface is difficult for oxidation, is difficult for influencing the outward appearance of workpiece, good combination property, and preparation method of the present invention is simple, and cost is low, is fit to scale operation.
