Abstract
An improved vacuum sputtering surface processing method includes the following steps that (1) pretreatment is conducted on the surface of a workpiece to be treated; (2) UV medium paint is sprayed for ultraviolet light curing or medium powder (medium paint) is sprayed for thermal curing; and (3) vacuum sputtering of chromium is conducted to obtain a chromium-plated workpiece. The improved vacuum sputtering surface processing method has a low reject ratio, low cost and good environmental protection property, and it is unnecessary to spray varnish to protect the workpiece.
Description
Technical field
The present invention relates to process of surface treatment, especially a kind of vacuum splashing and plating surface treatment method.
Background technology
Chromium is a kind of silvery white metal of micro-band blue cast, and chromium coating chemical stability is good, reflective good (namely mirror effect is good), can keep gloss for a long time and nondiscoloration in normal atmospheric environment.Chromium surface hydrophobic and oil repellent is not easily contaminated, and coating is firmly not easily scratched.The class of decoration chrome plating energy Integral lifting product, is widely used in the decorations such as the first-class sanitaryware of the fire hose, superior automobile wheel hub and panel decoration and household clothes.
Typical brass screw down bib cock chrome-plated process adopts water power plating, and because water power chromium plating relates to too many technique, produce a large amount of waste water, sexavalent chrome is strong carcinogen especially, is the technique not environmentally needing to eliminate; The metallic dust that polishing produces in addition has explosion hazard, and current national Work Safety Supervision Bureau prohibites.But the demand of chromium-plating effect still exists, vacuum splashing and plating technique is also had to meet the demands at present on the market.
The general technology of current vacuum splashing and plating, for automotive hub: fine grinding → (pre-treatment → spray black backing varnish dry →) spray medium paint or medium powder ovens dry → vacuum splashing and plating aluminium or chromium → spray varnish oven dry are dried → rolled off the production line in corase grind → pre-treatment → dust, if the technique of spraying in medium powder bracket can.Sputter Problems existing is: if aluminize, because aluminium is amphoteric metal, solidity to corrosion has problem; If chromium plating, then because current technical reason, can chap after spray varnish, it is very soft not spray then layers of chrome, not damage resistant.In the end need the protection of spray varnish to cause first-time qualification rate not high, thus cost is higher than water power plating.Except powder, also have two-layer paint, VOC discharge is more.And water tap, plastic component etc. also are not taked sputtering process to replace.
Summary of the invention
In order to the deficiency that the fraction defective overcoming existing vacuum splashing and plating surface treatment mode is high, cost is high, the feature of environmental protection is poor, the invention provides the vacuum splashing and plating surface treatment method of the improvement that a kind of fraction defective is lower, cost is low, the feature of environmental protection is good.
The technical solution adopted for the present invention to solve the technical problems is:
A vacuum splashing and plating surface treatment method for improvement, comprises the following steps:
(1), pre-treatment is carried out to pending workpiece surface;
(2), UV medium paint ultraviolet light polymerization or medium powder/medium paint thermofixation is sprayed;
(3), vacuum splashing and plating chromium, obtain chrome-plated workpieces.
Further, in described step (1), described workpiece is metalwork, carries out oven dry of dusting.
Or: in described step (1), described workpiece is plastic component, carries out oil removal treatment.
Further again, after pre-treatment, if the ground grinding abrasive paper of workpiece is coarser than No. 600, carry out spray base, dry.
After pre-treatment, spray base is carried out to plastic component, dry.
Further, in described (3), described UV medium paint is high rigidity polyfunctional group urethane acrylate system or amino acrylates system or Epoxy Phenolic Acrylates system or polyester acrylate system; Described medium powder or medium paint are following one or both and two or more mixing: 1. high rigidity epoxy systems, 2. phenolic system, 3. cyanate system, 4. poly-aryl ethane resin system, 5. polyimide system, 6. polybenzimidazole system, 7. Bismaleimide Resin, 8. benzocyclobutene.
Ying Du≤2H after described medium paint or medium powder solidify.
For metalwork, described priming paint is epoxy amino system, epoxy polyurethane system, epoxy novolac system, epoxy ester system, epoxy polyamide system, Amino-Polyester system or acrylic-amino system.
For plastic component, described priming paint is the dry alcohol acid system of thermoplastic systems, dual-component polyurethane system, low cross-linking UV system or gas.
In described (3), the target of the sputtering machine of employing is chromium, controls color by adjustment electric current and voltage and time length.
Technical conceive of the present invention is: the hardness being controlled final chromium coating by the hardness of adjustment medium paint (powder), thus can reach the requirement of decorative chromium without the need to spraying varnish.
Beneficial effect of the present invention is mainly manifested in: (1), increase the hardness of sputter layers of chrome by the hardness increasing medium paint (powder), saves spray varnish one procedure; (2), UV medium paint baking time is very short, and dust fall chance is few, and first-time qualification rate improves; (3) under existing processing condition, adopt medium paint to reduce VOC discharge, medium powder is zero release especially.
