Abstract
An optical copper surface delustring blackening treatment method relates to the technical field of metal surface treatment, and is characterized by including the following steps: placing a workpiece in anhydrous ethanol for soaking treatment; cleaning by an ultrasonic cleaning machine; putting into a liquid oxidizing salt for first oxidation treatment; again cleaning by the anhydrous ethanol and the ultrasonic cleaning machine; again putting into the liquid oxidizing salt for secondary oxidation treatment; putting into 100 DEG C pure water and anhydrous ethanol for soaking treatment; and finally passing through drying equipment to dry and wipe. The average pass rate of the product is more than 95%, the product color is uniformly matte, and the delustring effect is ideal.
Description
Technical field:
The present invention relates to field of metal surface treatment technology, be specifically related to a kind of optics copper surface dulling blackening process method.
Background technology:
Domestic in optical device shading at present, the electrochemical reaction blackening adopted when carrying out delustring process to copper surface, but product surface color disunity, extinction effect is undesirable.
Summary of the invention:
The object of this invention is to provide a kind of optics copper surface dulling blackening process method, its product average qualification rate reaches more than 95%, and the unified shaping Asia of product colour is photochromic, and extinction effect is desirable.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its treatment process comprises following steps:
(1) workpiece is placed in the dehydrated alcohol under normal temperature condition after foam washing process 30-40s, then rinses well with clear water;
(2) under normal temperature condition, workpiece is put into after Ultrasonic Cleaners carries out cleaning 5-10s, then rinse well with flowing clear water;
(3), reach the condition of 110-120 DEG C in temperature under, workpiece is put into after liquid oxidation salt carries out oxide treatment 30-35s, more fully clean up with the clear water that flows, namely complete first time oxide treatment;
(4) under normal temperature condition, the workpiece completing first time oxide treatment is put into dehydrated alcohol and processes 5-8s, when the micro-yellow of surface presentation or grey black, more fully clean up with the clear water that flows;
(5) under normal temperature condition, workpiece is put into after Ultrasonic Cleaners carries out cleaning 5-10s, then rinse well with flowing clear water;
(6), reach the condition of 110-120 DEG C in temperature under, workpiece is put into after liquid oxidation salt carries out oxide treatment 30-35s, until workpiece surface present black gray expandable or complete black time, more fully to clean up with the clear water that flows, namely complete second time oxide treatment;
(7) workpiece completing second time oxide treatment is put in the pure water of 100 DEG C and soaked 30-40min;
(8) by after carrying out immersion treatment 15-25s in workpiece dehydrated alcohol, then workpiece is put into drying plant and dry (temperature is no more than 200 DEG C);
(9) workpiece of oven dry is placed on non-dust cloth and wipes the floating ash in surface, namely complete production.
Described liquid oxidation salt adopts the aqueous solution containing 20-30wt% copper blackout salt.
The present invention has following beneficial effect: its product average qualification rate reaches more than 95%, and the unified shaping Asia of product colour is photochromic, and extinction effect is desirable.
