Abstract
A refractory antiwear lubricating paint is prepared from thermosetting epoxy resin, boron modified phenolic resin, MoS2, Sb2O3 and cerium fluoride. Its advantages are high antiwear, load-bearing and lubricating performance, and excellent refractory performance.
Description
Technical field
The present invention relates to a kind of high temperature resistant anti-wear lubricating coating and preparation method thereof.
Background technology
Resins, epoxy is a kind of good tackiness agent, its adhesivity is good, the cohesive strength height, creep is shunk little, belongs to the thermoset organic resin, but owing to itself constructional feature, resistance to elevated temperatures is relatively poor, under 400 ℃/1h condition, charing takes place not only, and ashing, thereby limited its use range to a great extent.The performance of Resins, epoxy depends on curing agents to a great extent, develops a kind of new solidifying agent and equals to develop a kind of new Resins, epoxy.In the many concrete application of this external Resins, epoxy, also will add multiple additives, each component may produce certain physical, chemical action each other, single performance often occurs and has improved, and over-all properties descends, and brings many difficulties for the research of material prescription.
Therefore, seek a kind of solidifying agent that improves the Resins, epoxy over-all properties, use the single component slip coating of its cured modified Resins, epoxy preparation, both lubricating and wear-resisting that tool is good and anti-adhesion performance, have great high-temperature resistant again, become modified epoxy, improve the key of its performance.
It is tackiness agent with Resins, epoxy that Chinese patent (94116246) discloses a kind of, molybdenumdisulphide is solid lubricant, Dicyanodiamide is a solidifying agent, butyronitrile 40 is an epoxy modifying agent, also add the slip coating of other properties-correcting agent simultaneously, good wear-resisting oilness and non-stick property are arranged, suitable to room temperature～200 ℃ metal to-metal contact part slip coating.But its component is various, exists obviously not enough on heat resistance.
Summary of the invention
The all good slip coatings of lubricated and abrasion resistance that the object of the present invention is to provide a kind of intermediate temperature setting high temperature to use.
Purpose of the present invention can realize by following measure:
High temperature resistant anti-wear lubricating coating is made up of binding agent, solidifying agent, solid lubricant, binder component.Tackiness agent of the present invention is selected thermosetting epoxy resin for use, and solidifying agent is a boron modified phenolic resin, and solid lubricant is a molybdenumdisulphide, and additive is antimonous oxide and cerium fluoride, and dispersion medium is a mixed organic solvents.
The weight percentage of slip coating consists of thermosetting epoxy resin 3～11%, boron modified phenolic resin 1～5%, molybdenumdisulphide 8～16%, antimonous oxide 0.1～0.5%, cerium fluoride 0.1～0.4%, mixed organic solvents surplus.
The mixed organic solvents volumn concentration that the present invention adopts consists of toluene 25%～35%, propyl carbinol 20%～33%, acetone 20%～33%, dehydrated alcohol 10%～20%.Selecting toluene, propyl carbinol, acetone, these four kinds of solvents of dehydrated alcohol, is factors such as the spraying coating process that taken into full account dry film, surface drying speed, film formation time, solidification value.
The boron modified phenolic resin that the present invention selects for use, oxygen index 0.48, decomposition temperature is greater than 500 ℃, and molecular structural formula is:
Introduce in this three dimensional structure flexible bigger bond energy higher-the B-O-key, and-B-O-key connects phenyl ring, make its toughness, thermotolerance all be better than connecting the resol of phenyl ring with the C-C key, when the hydroxyl in itself and the Resins, epoxy, methylol and epoxy group(ing) generation commissure curing reaction, can form the commissure reticulated structure, cohesive strength, snappiness, physical strength and the heat resistance of coating are fully guaranteed.
Molecular weight of epoxy resin is between 6000～11000, and oxirane value is 0.04～0.07 (100g/ epoxy equivalent (weight)).
The selected molybdenumdisulphide of the present invention is lubricant, and itself and resin matrix have good matching, and its purity is greater than 98%, and granularity should be less than 5 microns.
The selected additive of the present invention is antimonous oxide and cerium fluoride, and these two kinds of fillers and molybdenumdisulphide have good synergistic, and abrasion property, high thermal resistance, anti-specific pressure performance are improved, and its purity should be greater than 98%, and granularity should be less than 5 microns.
Preparation method of the present invention takes by weighing Resins, epoxy and boron modified phenolic resin by composition of the present invention and content, adds partially mixed organic solvent and makes material dissolution standby.Solid lubricant and additive are put into ball grinder, behind the mixed organic solvents ball milling of adding wetting amount, add dissolving good Resins, epoxy and boron modified phenolic resin then, the mixed organic solvents that adds surplus after the discharging gets final product.
The coating method of slip coating of the present invention is with spray gun the coating for preparing to be sprayed on piece surface under pressurized air (not having oil, anhydrous) or compressed nitrogen.Piece surface needs surface treatment such as oil removing, rust cleaning in advance.Part room temperature in clean air that spray is good is placed a few hours, puts into baking oven again and solidifies.Condition of cure: 120 ℃ ± 2 ℃, constant temperature 60 minutes, 150 ℃ ± 2 ℃, constant temperature 60 minutes, 180 ℃ ± 2 ℃, constant temperature 2 hours can use behind the furnace cooling.
The present invention is that a kind of boron modified phenolic epoxy group(ing) intermediate temperature setting high temperature uses anti-wear lubricating coating, it not only has good wear-resisting, carrying and lubricity, and has an outstanding high temperature resistance, the slide unit that has sprayed this paint coatings can solve the difficult problem that the epoxy group(ing) slip coating at high temperature uses in the medium-term and long-term use of high temperature (300 ℃～350 ℃) environment.
