Abstract
The utility model discloses a lead white-free copper-tin black door handle and relates to a door handle device. A black layer is electroplated on the surface of a copper base part, a protection layer is arranged outside the black layer, and the black layer and the protection layer are connected in a way of spraying varnish. A passivation layer can also be arranged between the black layer and the protection layer. The lead white-free copper-tin black door handle has the benefits that the black layer is fine in crystallization, flamboyant in appearance color and luster, firm in combination with the surface of the base part of the door handle, capable of avoiding peeling, shedding and stripping, very small in corrosion of metal of the base part of the door handle, long in service life of the door handle, uniform in the black layer and strong in covering power. Therefore, the surface of the door handle has higher hardness, good abrasion resistance, anti-high temperature capability and anti-corrosion capability.
Description
Technical field
The utility model relates to a kind of door handle.
Background technology
Door handle is the mechanical device that is used for the switch door that is fixed on a upper bracket, and along with the development that family and office decoration are decorated, people are increasingly high to the appearance requirement of door handle.The door handle of selling on the existing market is metal material and processes, being exposed in the air over a long time, and the time one is long, and can get rusty in the surface of door handle, and also influence promptly not attractive in appearance is used.
Summary of the invention
The purpose of the utility model is a said defective above being directed against, and a kind of long service life and unleaded copper-nickel alloy tin black door handle attractive in appearance are provided.
The purpose of the utility model is achieved through following technical scheme.
Unleaded copper-nickel alloy tin black door handle is characterized in that: copper substrate electroplating surface one deck black layer, and black layer is provided with layer protective layer outward, and black layer is connected with the mode of topping with lacquer varnish.
Unleaded copper-nickel alloy tin black door handle, it is characterized in that: electroplating parts substrate surface is provided with active layer, active layer electroplating surface one deck black layer, black layer is provided with layer protective layer outward, and black layer is connected with the mode of topping with lacquer varnish.
Also one deck passivation layer can be set between said black layer and topping.
Said unleaded copper-nickel alloy tin black door handle adopts following method preparation.
The preparation method of brass, bronze, red metal substrate door handle is: with not siliceous alkaline degreaser substrate carried out oil removing earlier, cleans up the metal surface, or with steam or solvent degreasing; Adopt unleaded copper-nickel alloy tin blackout electroplate liquid 333-400ml/L; Hydrochloric acid: 1-3ml/L (when needs are black especially, just needing to add), soak time: 30 seconds-3 minutes (meeting the requirements of blackness gets final product); Do not need air draft, substrate needs swing in the process.Substrate after the blackout cleans and seals lacquer immediately.
The preparation method of electroplating parts substrate towel rail is: with not siliceous alkaline degreaser substrate carried out oil removing earlier, cleans up the metal surface, or with steam or solvent degreasing; Unleaded copper-nickel alloy tin blackout electroplate liquid 333-400ml/L is adopted in activation in 0.5-2.0% sulfuric acid liquid, and hydrochloric acid: 1-3ml/L is (when needs are black especially; Just need to add); Soak time: 30 seconds-3 minutes (reaching the requirement blackness gets final product), not needing air draft, substrate needs swing in the process.Substrate after the blackout cleans and seals lacquer immediately.
After the substrate blackout, about also available potassium bichromate 40-50g/L passivation 30 paper money after again envelope coat with lacquer.
When the substrate of door handle turns black in batches, need to use single core filter to filter, being operated in normal temperature (20-30 ℃) situation can normally turn black, but in blackout more than 35 ℃, the firmness of coppery layer modelled after an antique is better.
Use the material of electroplating bath: available plastics, PVC, rubber, glass, polypropylene, polyvinyl etc.
The beneficial effect of the utility model is: the utility model is through the substrate electroplating surface one deck black layer at door handle, and the black layer crystallization is careful, and appearance luster is gorgeous; Combine firmly with the substrate surface of door handle; No peeling, come off and peel off, minimum to the corrosion of the parent metal of door handle, the door handle long service life; Black layer is even, and hiding power is strong.Make the door handle surface have higher hardness, good abrasion resistance, high-temperature resistance and antiseptic power.
