Abstract
The invention relates to a high-temperature and anti-oxidation lubricant coating for a superstrength steel plate hot stamping piece, substantially comprising a carbon nano tube, quaternary boron nitride powder, ionic liquid, aluminium powder, magnesium powder and dimethyl silicone polymer. By using nanoparticles and the ionic liquid as raw materials, binder with stable property under high temperature is prepared by the sol-gel technology so as to effectively prevent the plate from being oxidated and improve the associative property between the coating and the substrate without falling off; after solid lubricant is added, the friction property of the plate is improved and the forming property of the plate is enhanced; as metal particles are added, the thermal conduction, the electric conductivity and the inoxidability of the coating are promoted; and the plate can be applicable to direct hot stamping forming technology and indirect hot stamping forming technology without the subsequent descaling treatment and rust prevention treatment after being formed.
Description
Technical field
The present invention relates to a kind of coating, especially, it is used for hot press-formed ultrahigh-strength steel plates resistance to high temperature oxidation, and can improve the coating of sheet material frictional behaviour, belongs to technical field of hot stamping and forming and technical field of coatings.
Background technology
Hot press-formed is a technology that is specifically designed to manufacturing super-high strength steel stamping parts, the part that makes by this method, intensity with superelevation, good dimensional precision, be applied to automobile manufacturing field, can improve the collision safety performance of automobile, alleviate tare, meet energy conservation and environment protection, be subjected in recent years paying close attention to widely.
The problem of oxidation of high temperature sheet material is a difficult problem of the hot press-formed technology of puzzlement.Though sheet material is to heat under the atmosphere of gas shield, but, transferring to from process furnace the process of hot-forming die, sheet material under the high temperature contacts with air, and the surface can form one deck oxide skin, and this oxide skin negative impact is very big, when punching press, come off easily, attached to die surface, must in time remove, otherwise can influence the continuity of production; And attached to the oxide skin on drip molding surface, because poor with the associativity of part base solid, before the processing of spraying the raisings part resistance to rust of etc.ing, must remove by methods such as shot-peenings, this has just increased and has become the product cost, and makes the production cycle prolongation; Oxide skin hardness is higher, might scratch die surface.
In order to address this problem, people have proposed the method at plate surface coating layer protective layer.Present widely used method is to plate a supercoat on the surface of sheet material, utilizes the solid solution phase protection matrix metal that forms between coated material and the matrix not oxidized.This method is preventing to have obtained certain effect aspect the sheet metal oxidation, and still, because the restriction of technology, this method can only be applied to the direct heat process for stamping and forming at present, the comparatively simple part of production shape.
Coating is a kind of cost-effective method that prevents the sheet material high temperature oxidation, can avoid iron and steel generation oxidation, and is not subjected to the restriction of performing member complicated shape or size, and technology is simple, and is easy to operate, good economy performance.At present, the domestic coating of developing several high temperature oxidation resistings, but because the characteristics of self all are not suitable for hot press-formed technology.
Ionic liquid refers to be the fused salt of liquid state more when being lower than 100 degrees centigrade, volatility is low, the thermostability height, not flammable, advantage such as easy to use, be the ideal substitute of traditional volatile solvent, it has avoided the problems such as serious environmental that use causes, health, safety and equipment corrosion of conventional organic solvents effectively, is genuine environmentally friendly green solvent.
For hot stamping parts of ultrahigh strength sheet steel coating, must satisfy following the requirement: the first, have the anti-oxidation performance of good high-temperature; The second, at high temperature forming property is good; The 3rd, do not come off in mould after the quenching that is shaped, guarantee the continuity of producing; The 4th, conductivity is good after the thermoforming, satisfies the spot welding requirement.
Be applied to hot press-formed coating at present and can't satisfy above requirement.
Summary of the invention
The purpose of this invention is to provide a kind of ultrahigh-strength steel plate heat-punch member high-temperature oxidation resistant lubricate paint, with nanoparticle and ionic liquid is raw material, utilize gel process to develop a kind of binding agent of stable performance at high temperature, in conjunction with solid lubrication particle and aluminium, magnesium metallic particles etc., overcome the above problems.
Purpose of the present invention realizes in the following way:
Coating of the present invention comprises following main component (pressing massfraction):
Carbon nanotube 5-15%, ionic liquid 30-40%, aluminium powder 15-25%, magnesium powder 30-35%, solid lubricant 10-15% sacrifices organic matter 5-10%, dispersion agent 1-2%.
Described ionic liquid is alkyl imidazole a tetrafluoro borate or 1-butyl-3-N-Methylimidazoleacetic salt.
Described solid lubricant is a nitrogenize four boron powders, selects for use the reason of a nitrogenize four boron to be that it is high temperature resistant, and fusing point is up to 2350 ℃.
Described aluminum particle size is less than 3 μ m.
Described magnesium powder particles size is less than 3 μ m.
Described dispersion agent is a polydimethylsiloxane.
The effect of described sacrifice organic matter in coating is; after sheet material is heated to high temperature; this sacrifice organic matter at first with oxygen reaction; by the metallic particles in the protective cover of burning of self; guarantee that coating still has good electrical conductivity after hot press-formed; the selected sacrifice organic matter of the present invention is the polymer of 1,5 cyclooctadiene, and chemical formula is (C
8H
12)
n, molecular weight is between 3000-9000.
Coating method of the present invention is existing will the cleaning in the alkaline cleaner of hot press-formed boron alloy sheet material under 60 ℃ of temperature, wash then, dry, carrying out degreasing and rust removal handles, afterwards with spray gun with the paint spay-coating for preparing surface at sheet material, coating thickness is 5-7 μ m, solidify 4-6min down at 300 ℃, can use after the cooling.Sheet material after the spraying is being heated to after 880-900 ℃, and coating can form the coating zone of influence of one deck 30 μ m left and right sides degree of depth in matrix, forms layer protective layer at plate surface, prevents the sheet material oxidation; The interpolation of solid lubricant has reduced the friction between sheet material and the mould, helps being shaped; Because added the sacrifice organic matter, effectively protected metallic particles not oxidized, guaranteed the electroconductibility of coating; The interpolation of magnesium powder makes coating have good solidity to corrosion, and described coating and sheet material matrix bond are fine, does not therefore need to carry out follow-up descaling and spray treatment after being shaped.Ion liquid use has reduced the volatilization of obnoxious flavour, meets environmental protection requirement.
