Abstract
The invention belongs to the plating of metallic substance.Its processing step is: 1. surface treatment (additive is a L-Q type cleaning agent); 2. (additive is the L-C deposit fluid) handled in electroless plating; 3. mechanical cold welding (collision medium is the mixture of one or more granulometric composition in granulated glass sphere and tetrafluoroethylene, polyethylene, the polypropylene, and additive is the mixed solution of promotor L-X and promotor L-Y); 4. antioxidation treatment (additive is a L-D antioxygen confining liquid); 5. drying treatment.The present invention can enlarge the range of application of traditional cold welding technique, and the cold welding layer of the metal plating piece of making is even, strong adhesion, and corrosion resistance is good.
Description
The present invention relates to the plating of metallic substance, especially relate to machinery cold welding craft and additive thereof.
At present, the plating of metallic substance has methods such as plating, hot dip process and mechanical plating, the above two use range is wide, but metallic matrix easily produces " hydrogen embrittlement " phenomenon, and the latter's range of application and condition harshness, can only be used for little, the lightweight spring part of size, and use temperature must be controlled at more than 24 ℃.
Purpose of the present invention is intended to design a kind of applied range, non-environmental-pollution, and the machinery cold welding craft of little power consumption makes it to be applied to elastic component, but also can be applied to the metal protection processing of larger-size malleable steel part.
Design technology scheme of the present invention is: adopt the surface treatment electroless plating to handle four technological processs of mechanical cold welding and drying treatment.Simultaneously, for the fastness and the work-ing life of improving product, after the mechanical cold welding process, increased the antioxidation processing technology process again one.Wherein the surface-treated processing step is metalwork to be put into L-Q type cleaning agent soaked 30-60 minute, in order to remove the dirt of metallic surface.It then is the metalwork after handling through last process to be put into the L-C deposit fluid soaked 3-5 minute that electroless plating is handled, also can be placed in the drum that is added with the L-C deposit fluid and rotate 3-5 minute, set up a transition layer at metal base surface, make the cold welding metal level can be well and matrix bond.The machinery cold welding craft process is metalwork and collision medium, metal powder, promotor L-X and the promotor L-Y that will handle and rinse well through electroless plating, together put into drum, add suitable quantity of water, rotated 15-30 minute, collision medium is: the mixture of one or more granulometric composition in granulated glass sphere and tetrafluoroethylene, polyethylene, the polypropylene.The antioxidation treatment step is the metalwork after handling through last process to be put into antioxygen encapsulant L-D solution soaked 1-3 minute, can make the cold welding layer have good resistance of oxidation.At last metalwork is heated, drying treatment, can obtain sticking power good metal cold welding layer.
The composition and the proportioning of the various additives that add in above each processing step are as follows:
(A) L-Q type cleaning agent: with citric acid 500 grams, 100 milliliters of 0 π-10 solution, the mixing solutions of 1000 milliliters of preparations of water.
(B) L-C deposit fluid: with mantoquita or pink salt 90 grams, propenyl thiocarbamide 30 grams, 2.4 milliliters of 10% sulphuric acid solns, the mixing solutions of 1000 milliliters of preparations of water.
(C) L-X promotor: with single nickel salt 30 grams, nickelous chloride 15 grams, Sodium sulfate anhydrous.min(99) 60 grams, molecular weight are polyoxyethylene glycol 50 grams more than 6000, the mixing solutions of 1000 milliliters of preparations of water.
(D) L-Y promotor: with citric acid 1000 gram, stannous sulfate 200 grams, stearic acid 100 grams, tartrate 200 grams, citric acid hydrogen diamine 40 grams draw back and add water in the mixture of powder 100 grams and tin protochloride 200 gram preparations and be ground to pasty state.
(E) L-D antioxygen encapsulant: (by weight percentage) with lithium silicate 15%, potassium bichromate 1%, and nonionic surface active agent 3% and 81% the formulated mixed solution of water adopt this encapsulant, can improve the fastness and the erosion resistance of product.
The present invention adds collision medium in the drum and is the mixture of one or more granulometric composition in the tetrafluoroethylene, polyethylene, polypropylene of the granulated glass sphere of 70%-80% and 20%-30% in the machinery cold welding craft process.Because the latter's proportion is little, roll the shock absorption of having floated on the surface when hitting, after the metalwork that has solved large-size collided in drum, the granulated glass sphere plane of disruption scratched the cold welding top layer and glass powder is attached to a difficult problem that makes cold welding layer thickness inequality on the product surface, simultaneously the also corresponding cost that reduced.
The present invention places promotor L-X in the drum and the volume ratio of promotor L-Y is 1: 1, adopts this promotor can make more than the use temperature range extension to 0 ℃ of whole machinery cold welding craft.
The advantage of the relative prior art of the present invention is as follows:
1, the machinery cold welding craft scope of application is widened, not only can be used for size, the less elastic part of weight, but also applicable to larger-size malleable iron hot-water heating spare, standard web member and nail, tapping screw etc.
2, the use temperature scope is by being extended to more than 0 ℃ more than 24 ℃.
3, power consumption is little, and cost is low, non-environmental-pollution.
4, improve the fastness and the erosion resistance of metallic article.
Embodiment: with 200 kilograms of malleable iron hot-water heating spares (external diameter 100mm), putting into L-Q type cleaning agent groove soaked 40 minutes, place in the drum with L-C deposit fluid again after the taking-up and rolled 4 minutes, then water cleans up, place once more linear velocity reach 25-30 rice/minute drum in rotate, give in the drum and add earlier 100 kilograms of the mixing collision mediums formed by the granulated glass sphere (weight percent) of 20% tetrafluoroethylene and 80%, 2.4 kilograms of zinc powders, promotor L-X400 milliliter, promotor L-Y400 milliliter and suitable quantity of water.Then hot-water heating spare is taken out to drop in the antioxygen encapsulant L-D solution and soaked 2 minutes, carry out heat drying again and handle.The cold welding layer of the malleable iron hot-water heating spare of making is even, strong adhesion, and the copper-bath that can bear more than 5 times soaks, and corrosion resistance is good.
