Abstract
An antirust oil for antistatic soft membrane is prepared from basic oil, filming agent, antirusting agent and other additives.
Description
One. the technical field of the invention galvanic corrosion science and guard technology
Two. technical background of the present invention
Metal is modern industry, national defense industry, petroleum industry, the most important structured material of measurement instrument industry and other departments.But metal very easily is subjected to the chemistry of external environment and medium or electrochemical action to cause rotten and damage, and this phenomenon is called metallic corrosion.Using slushing oil is a kind of comparatively desirable effectively means of defence as temporary protection, and it uses and remove all more convenient.The present electrostatic painting process that extensively adopts of each big steel factory of the whole nation, cold rolling mill has overcome shortcomings such as the big and oiling of the oil consumption that original roller coating technology brought is inhomogeneous, has improved production efficiency, has reduced production cost.Because electrostatic spraying is with the electrostatic sprayer energising, forms powerful electrostatic field, under electrostatic forcing, makes electrostatic painting anticorrosive oil, evenly is adsorbed on the surface of steel plate.Therefore electrostatic painting anticorrosive oil has been proposed higher, harsher requirement, it not only will have good slushing oil performance, also must possess certain insulativity simultaneously.General homemade electrostatic sprayer to the requirement of voltage breakdown than import want high, need be more than 45KV, this is the prerequisite oily electric property of high voltage electric equipment.Consider that based on above-mentioned condition we develop and have invented a kind of novel high-quality antistatic spray oil, to adapt to growing industrial production demand.
Three. summary of the invention of the present invention
The present invention is directed to electrostatic painting process to the various performance demands of slushing oil, base oil, membrane-forming agent, rust-preventive agent and each self-applying of other interpolation assistant agents and compatibleness have each other been inquired into, the antistatic soft film anti-rust oil prescription is screened, and, finally determine a kind of novel antistatic soft film anti-rust oil with wide application prospect by the evaluation of various performances.The present invention is design like this:
Novel antirust oil of the present invention mainly is made up of base oil, membrane-forming agent and rust-preventive agent three parts, and they play a part different separately each other, and compatibility forms an integral body mutually again.1. the effect of base oil in the slushing oil
Base oil can play carrier function, make rust-preventive agent can be in oil homodisperse; Can play oily effect effect again.Be that base oil carries out physical adsorption in the few metallic surface of polar molecule absorption.The alkyl of base oil molecules is deep between the rust-preventive agent molecule of oriented adsorption simultaneously; stop up hole jointly by Van der Waals gravitation and rust-preventive agent molecule; make on the metallic surface adsorption film more compact and complete, and make the firm inadequately polar molecule difficult drop-off of absorption, thereby more effectively protect metal.2. the selection of base oil in the slushing oil
Base oil proportion in slushing oil is bigger, and the present invention screens the carrier that withstand voltage properties good basis oil serves as rust-preventive agent, and this is the prerequisite of the antistatic spray oil of development.Theoretically, it is few more to contain unsaturated link(age) and impurity in base oil, and its molecular structure is just stable more, and resistance to pressure is just good more.Several base oil of the present invention carries out withstand voltage and viscosity test, and the result is as shown in table 1.
Table 1 base oil performance test
| The base oil trade mark or title | The oil product outward appearance | 40 ℃ of mm of kinematic viscosity 2/s | Pressure (KV) |
| 46# machine oil | Light yellow | ???40 | ??34 |
| Domestic kerosene | Water white | ???1.28 | ??15 |
| ??75SN | Light yellow | ???10.2 | ??50 |
| ??150SN | Light yellow | ???40 | ??58 |
| Solvent oil | Water white | ???1.37 | ??60 |
| Dewaxed base oil | Water white | ???11.8 | ??40 |
| The 25# transformer oil | Water white | ???9.79 | ??57 |
Can be obtained by table 1, the withstand voltage properties of solvent oil is best, is 150SN, 25# transformer oil, 75SN, dewaxed base oil, 46# machine oil and domestic kerosene secondly.Selective solvent oil, 150SN, 25# transformer oil carry out 3. formula developments of the present invention as base oil thus
The present invention at first presses different ratios with the base oil of selected withstand voltage properties excellence, be modulated into the mixed oil of different viscosity, measure the resistance to pressure of mixed oil, the oil viscosity of finding to be in harmonious proportion is little to the resistance to pressure influence, secondly, the present invention investigates the base oil with certain withstand voltage properties, and its viscosity is to the influence of rustless property.Select two kinds of base oils that viscosity is different, add identical composite additive, do the experiment of carbon steel salt spray resistance, its result is as shown in table 2;
Table 2 base oil test for rust preventing ability
| The oil product numbering | 40 ℃ of mm of viscosity 2/s | Form | Salt fog sinkability ml/h | 0 grade of time of salt fog (h) |
| ??F11 | ???13.5 | 62%25# transformer oil+38% additive | ??1.3 | ???216 |
| ??F12 | ???23 | The 62%150SN+38% additive | ??1.3 | ???96 |
As shown in Table 2, the less base oil of usefulness viscosity compares with the bigger synthetic slushing oil of base oil of viscosity, and its salt spray resistance will be got well.Because the volatility of light oil is greater than the high oil of viscosity, behind the comparatively high temps, the lightweight oil volatilization has stayed quite spissated additive on the test piece surface, has improved its rust-preventing characteristic in hanging drip-dry and proofing box; Simultaneously rust-preventive agent molecule suffered resistance in low viscous base oil is little, easily under the metal polar attracts, in the contact surface enrichment of metal and slushing oil, oneself polar end is adsorbed onto the metallic surface; And the molecular geometry volume that viscosity is little is also little, fills up the adsorption layer of rust-preventive agent and metallic surface easily, makes the absorption protective layer tightr, has stoped close to the metallic surface of water molecules and oxygen molecule effectively.Therefore when development slushing oil prescription, the control certain viscosity not only helps the needs of spraying coating process, and the improvement of rustless property is also had certain help.4. the selection of membrane-forming agent
For adhesion strength and the dispersed uniform of strengthening slushing oil, resist that rust-preventive agent is because of the loss that causes of washing away of the salt fog and the dew that condensed in salt-fog test and the humid heat test, it is very necessary adding a certain amount of membrane-forming agent.Membrane-forming agent is some materials with larger molecular weight, as machine oil, Vaseline, paraffin etc.It can associate into membranaceous skeleton in the metallic surface, serve as carrier with base oil, rust-preventive agent is evenly filled form fine and close protective film, effectively defends the erosion of various extraneous factors.For screening the rustless property of various membrane-forming agents, several different membrane-forming agent prescriptions are carried out the salt spray resistance simultaneous test, it the results are shown in Table 3;
The salt spray resistance of table 3 membrane-forming agent
| Prescription | ????A0 | ????A1 | ????A2 | ????A3 |
| Base oil % | ????85 | ????80.5 | ????80 | ????84 |
| Rust-preventive agent % | ????15 | ????9.5 | ????10 | ????10 |
| Vaseline % | ????0 | ????5 | ????0 | ????0 |
| Oxidized petrolatum % | ????0 | ????0 | ????10 | ????0 |
| Artificial rosin % | ????0 | ????0 | ????0 | ????3 |
| ????HYB％ | ????0 | ????5 | ????0 | ????3 |
| Salt-fog resistant time/h | ????24 | ????48 | ????72 | ????168 |
As can be known from the above table, when only serving as membrane-forming agent with base oil, although the consumption of rust-preventive agent is higher, salt fog resistance is very poor.And when composite during as membrane-forming agent with HYB and artificial rosin, its salt fog resistance is improve greatly but.The formed protective film of this explanation base oil, not only thin the and poor adhesive force of rete can't be resisted salt fog at all and drip and reveal the erosion corrosion that is produced, and causes salt-fog resistant time very short; And HYB and artificial rosin are compound; because of its molecular weight bigger; and has stronger polar functional group; when the associating oil film skeleton of itself and the abundant miscible formation of base oil; rust-preventive agent can be filled between skeleton by homodisperse, makes and forms strong adsorption layer between polar functional groups numerous in membrane-forming agent and the rust-preventive agent and the metal, block water molecule and oxygen molecule infiltration; slow down the corrosion of metallic surface, play a very good protection.
But it is not enough that membrane-forming agent only has good rust-preventing characteristic, and resistance to pressure preferably also need be arranged, and only in this way could adapt to the needs of antistatic spraying coating process.Screen several rustless properties membrane-forming agent preferably, carry out the resistance to pressure test, its result is as shown in table 4;
The resistance to pressure of several different membrane-forming agents of table 4:
| Membrane-forming agent | Membrane-forming agent add-on % | Voltage is worn in resistance |
| Oxidized petrolatum | ????1 | ????34 |
| Artificial rosin | ????5 | ????30 |
| ????HYB | ????3 | ????46 |
As shown in Table 4, its resistance to pressure of different membrane-forming agents differs greatly, and is best with HYB wherein, and artificial rosin is for the poorest.5. the membrane-forming agent optimum amount determines
Experiment shows that the HYB addition has higher resistance to pressure between 1～3 gram, and changes little each other; But along with the increase of HYB addition, its resistance to pressure obviously descends.In addition, when the HYB addition in 3 whens gram, its salt fog resistance obviously is better than other additions.Thus the present invention be preferably film HYB addition be 3 the gram.6. the adsorption of rust-preventive agent
Rust-preventive agent in the slushing oil is to have the polar organic compound, also is tensio-active agent, and it is made up of asymmetric polarity and nonpolar two portions.The polarity part of rust-preventive agent molecule forms oriented adsorption in oil-metallic surface, thereby reduces the activity in active centre, metallic surface, and advancing of block water molecule and oxygen molecule slows down the corrosion process greatly; The nonpolar part of rust-preventive agent molecule forms one deck hydrophobicity protective membrane in the metallic surface, stopped the relevant electric charge of participation corrosion reaction or moving of material, and erosion rate is reduced.7. the selection of rust-preventive agent
Because the energy level distribution range in active centre, metallic surface is wider, single rust-preventive agent can not match fully, so select multiple additives, in the hope of bringing into play the effect of cooperative compensating each other, reaches best protection effect.In research process, take all factors into consideration kinematic viscosity, flash-point, the colourity and all multifactor of slushing oil, the utilization orthogonal design is designed the L of eight factors, three levels to related rust-preventive agent and assistant agent
18(3
8) orthogonal table, through overtesting, finally determine the best compatibility and the consumption of various rust-preventive agent, assistant agent in the slushing oil prescription.In sum, the prescription of novel antirust oil of the present invention is as follows:

(5)701????????????2～5％????????????(6)703????????????????0～2.5％
(7) 705 1～5% (8) 746 and additive 4%
In sum, the antistatic slushing oil prescription that filters out in a large amount of experiments of process of the present invention proves through the test of every performance index, it had both had rustless properties such as good salt spray resistance, moisture-proof heat, stronger antistatic effect is arranged again, and it has good surface appearance, simple modulation process, rational manufacturing cost, can satisfy the demand of electrostatic painting process fully, have less investment, instant effect, market is big, characteristics such as safety, environmental protection are a kind of products that broad prospect of application is arranged.
