Abstract
The present invention discloses emulsified antirust lubricant for drawing, which is composed of a lubricant component (A), an emulsifying agent, an antirust component (B), tap water, a water softening agent and a sterilizing agent, wherein the component (A) is prepared from mineral oil, animal and plant oil, chlorocarbon and vulcanized plant oil. The component (B) is prepared from fatty acid, sulphonate, boric acid, alkyl alcohol amine and polyethylene glycol fatty alcohol ether. The emulsified antirust lubricant has good lubricating property (the PB value of an extreme boundary lubrication performance index is larger than 880N) and high antirust performance (the pH value is larger than 8.0, and the part stock antirust period is more than 30 days). In addition, the emulsified antirust lubricant has the characteristics of favorable cleaning performance, no environmental pollution, low cost, etc.
Description
The present invention relates to a kind of lubricant in the processing of steel plate drawing and moulding, particularly a kind of emulsified antirust lubricant for drawing.
Steel plate must apply one deck lubricant on the working-surface of blank surface of steel plate or mould in punching press drawing and moulding process.The effect of lubricant has two: the one, reduce die wear, prolong die life, reduce the stamping parts surface cut, prevent drawing crack, guarantee that the demoulding is smooth; Another effect is antirust, especially more good anti-rust properties will be arranged for non-plating (or being coated with) layer steel plate.For example: the oil-in-water type of U.S. Houghton company draws agent, and its lubricity is better, but its rustless property is relatively poor, and is especially even more serious when longer in the middle operation shelf-time.The used oil-in-water type of German in addition Audi company draws agent (product standard number for VW-294179), be mainly used in the production automobile panel, the said firm draws in the agent standard at oil-in-water type and stipulates: pH value in use should remain on 7.85 ± 0.2, and measured value is about 7.0.And facts have proved that the oil-in-water type of this potential of hydrogen draws the rust prevention during manufacture requirement that agent also can only be satisfied plating (or being coated with) layer steel plate, bad to common cold-rolled steel sheet rustless property.
The purpose of this invention is to provide a kind of existing good lubricating property and have again preferably that the oil-in-water type of rustless property draws agent.
To achieve these goals, the present invention is made up of lubricant composition (A) and emulsifying agent, rust-preventive agent component (B) and tap water, water-softening chemicals, disinfectant, and component (A) is made up of Dormant oils, animal or plant oil, chlorocarbon, vulcanized vegetable oil.Wherein Dormant oils can be machine oil N
5～N
46, but N preferably
15～N
32Animal oil or vegetables oil can be butter, sheep oil, soya-bean oil, rape oil, but butter preferably; Its cl content of chlorocarbon selects 42%～52%, but preferably 52%; Vulcanized vegetable oil also can be selected other sulfide for use, and as olefine sulfide, sulphur benzyl etc., but vulcanized vegetable oil is the most cheap.Component (B) is made up of lipid acid, sulfonate, boric acid, alkyl alcoholamine, polyoxyethylene aliphatic alcohol ether.Wherein lipid acid can be naphthenic acid, the acid of appropriate that, ricinolic acid, C
15～C
17Saturated fatty acid, C
15～C
17Unsaturated fatty acids, but preferably oleic acid or hard fatty acids; Sulfonate can be sodium salt, calcium salt, the barium salt of sulfonic acid, and sulfonic acid also can be mahogany acid or Viscotrol C sulfonic acid; Boric acid can be selected other organic acid such as n-nonanoic acid or capric acid for use, but the boric acid price is more cheap; Alkyl alcoholamine can be Monoethanolamine MEA BASF, diethanolamine, trolamine, but trolamine preferably, during its consumption should guarantee fully and lipid acid, and makes and draws agent and be alkalescence, and pH value is greater than 8.0; Polyoxyethylene aliphatic alcohol ether can be the Soxylat A 25-7 of primary alconol, secondary alcohol.
Emulsified antirust lubricant for drawing of the present invention, the per-cent that component (A) and each composition of component (B) account for this emulsified antirust lubricant for drawing gross weight is: Dormant oils 20～50%, animal or plant oil 10～15%, chlorocarbon 2～10%, vulcanized vegetable oil 1～3%, lipid acid 5～25%, sulfonate 4～8%, boric acid 0.5～2%, alkyl alcoholamine 8～16%, polyoxyethylene aliphatic alcohol ether 0.5～2%.The add-on of tap water is 50～100% of lubricant composition (A) and emulsifying agent, rust-preventive agent component (B) gross weight.Account for the water-softening chemicals EDTA of said mixture gross weight 0.005%, 0.005% disinfectant triazine extra again the adding.
During modulation, the component (A) that mixes up according to the above ratio mixed with component (B) carry out emulsification, dilute, add water-softening chemicals EDTA and disinfectant triazine at last with tap water.
The present invention has good lubricating property (its extreme boundary lubrication performance index PB value is greater than 880N) and higher rustless property.Also have good cleaning performance, free from environmental pollution, characteristics such as cost is low in addition.
The present invention is described in detail with embodiment below, and be example with modulation 1000kg emulsified antirust lubricant for drawing.
N with 225kg
32Machine oil, 60kg make with extra care butter, 25kg chlorocarbon (cl content is 52%), the 10kg vulcanized vegetable oil fits over together and reconcile into component (A).Fit over together and be modulated into component (B) with 100kg lipid acid, 20kg sodium sulfonate, 5kg boric acid, 50kg trolamine, 5kg polyoxyethylene aliphatic alcohol ether again.Component (A) and component (B) mediation are carried out emulsification together, add the 500kg tap water again and dilute, additionally add 50kg water-softening chemicals EDTA and 50kg disinfectant triazine at last again, stir through mediation again.
