Abstract
The antiwear lubricating paint for engine piston ring is one kind of dry film lubricant. The paint consists of compoiste adhesive, antiseptic additive, antiwear additive, surfactant and dispersing medium. It is painted to the surface of piston and high temperature cured to form firm, compact and dense solid film with excellent antiwear resistance, high impact resistance and good sealing performance.
Description
Technical field
The present invention is a kind of engine piston ring wear proof lubricating painting materials, belongs to dry-film lubricant.
Background technology
Obtained using widely and having obtained good effect at a lot of fields dry-film lubricant at present, but not all dry-film lubricant can go to deal with problems under a certain special operation condition condition.Piston ring is in the to-and-fro movement of cylinder high speed engine, especially in new cylinder body, be easy to cause pulling of cylinder surface, cause cylinder to scrap, a lot of at home piston ring factories handle the piston ring surface targetedly to this problem, handle as surface hardening, sulphonitrocarburizing, bonderizing etc., all well do not address the above problem, at first be that cylinder body and piston ring need the initial stage break-in, most importantly can't solve the stopping property of cylinder body and piston ring, and its engine horsepower is descended.
Summary of the invention
The object of the present invention is to provide a kind of engine piston ring wear proof lubricating painting materials.
Purpose of the present invention can realize by following measure:
Engine piston ring can address the above problem well with the use of wear proof lubricating painting materials, mainly be in use, coating on the ring, can be transferred to dry film the surface of fastness and form new transfer film, the raising that this is just very big the mutual transfer of dry film between two dual faces, and reach well wear-resisting and sealing.
Engine piston ring uses wear proof lubricating painting materials by compound binding agent, anticorrosive additive, and anti-wear additive, tensio-active agent and dispersion medium are formed.Binding agent of the present invention is selected polyamide-imide resin for use, high molecular expoxy resin, resol; Solid lubricant is a tetrafluoroethylene, perfluoroethylene-propylene; Rare earth fluoride, antimonous oxide are anticorrosive additive; Plumbous oxide, Cadmium oxide, titanium dioxide are anti-wear additive; This 20 or cetyl trimethylammonium bromide be tensio-active agent; Dispersion medium is selected mixed organic solvents for use.
Coating of the present invention is made up of A component and mixed organic solvents, the weight percentage of A component form be polyamide-imide resin 30.0～53.0, high molecular expoxy resin 15.0～21.0, resol 5.0～11.0, tetrafluoroethylene 12.0～22.0, perfluoroethylene-propylene 5.0～8.5, plumbous oxide 1.0～7.0, Cadmium oxide 1.0～9.5, antimonous oxide 5～20, titanium dioxide 0.5～2.5, this 20 or cetyl trimethylammonium bromide 1.0～5.0, fluoridize alkene soil surplus; The add-on of mixed organic solvents is 1～1.5 times of A composition weight.
It is butanone 15～25% that the volumn concentration of mixed organic solvents is formed, dimethyl formamide 45～70%, and toluene 10～25%, surplus is a pyrrolidone.
The present invention selects compound binding agent for use, the cohesive strength height, and wear resistance, heat resistance are fully guaranteed.
The polyamide-imide resin that the present invention selects for use, absolute viscosity are 1500～6000 centipoises, and its structural formula is:
R represent methylidene wherein, n is 1 to 3 integer.
The high molecular expoxy resin molecular weight that the present invention selects for use is more than 11000, and oxirane value is 0.04～0.07 (equivalent/100 grams).
The tetrafluoroethylene purity that the present invention selects for use is greater than 97%, and granularity is below 10 microns.
The rare earth fluoride that the present invention selects for use is one or more compositions of lanthanum fluoride, cerium fluoride, mishmetal.
The resol that the present invention selects for use is the solid resole.
The adding of the solid lubricant very low perfluoroethylene-propylene of tetrafluoroethylene and frictional coefficient, rare earth fluoride, antimonous oxide can increase the antiseptic property of dry film.Cross-link intensity significantly improved and improves the anti-pressure ability and the wear resisting property of dry film own when plumbous oxide compound, the oxide compound of cadmium and the adding of titanium dioxide can make dry film solidify.
Compound binding agent in the above-mentioned prescription of the present invention, solid lubricant, anticorrosive additive, anti-wear additive, tensio-active agent all is solid state, powdered or thick liquid before making dry-film lubricant.Therefore when making dry film, need be made into the dry film spray and spray, exactly the solid particulate in the prescription is scattered in the dispersion medium, after fully grinding by tapered mill, make the soup compound spray.Dispersion medium is selected the mixed solution of butanone, dimethyl formamide, toluene, pyrrolidone for use, add-on is 1～1.5 times (weight) of material, dispersion medium consist of butanone 15～25%, dimethyl formamide 45～70%, toluene 10～25%, surplus are pyrrolidone (volume percent content).Why selecting this four kinds of solvents, is the spraying coating process of fully having investigated dry film, surface drying speed, film formation time, factors such as solidification value.
Coating of the present invention is fit to be sprayed on various carbon steels, steel alloy, aluminium, copper, and the machining surface of various other alloy materials and lapped face also can be sprayed on through various surface-treated metallic substance workpiece surface such as sandblast, phosphatization, passivation, anodizing.
Maximum characteristics of the present invention are that the wear-resistant life-span is good, (engine piston ring) with strong points, the main performance index of product is as follows: test item measuring method test conditions measurement result salt fog GB1771-79＞500 hours snappiness GB1731-79 0.5mm cohesive strength GB1720-79 wear-resistant life-spans of 1 grade of shock resistance GB1732-79 50kgcm
