Abstract
The present invention relates to cleaning agent fields, more particularly to the decoating liquid and preparation method thereof of automobile die PVD a kind of, for the decoating liquid by weight percentage by the deionized water of the sodium permanganate of 10-30%, the potassium hydroxide of 10-30% and 40-80%, the present invention mainly carries out strip processing to automobile die PVD using the strong oxidizing property that sodium permanganate has under epistasis environment.In the prior art, domestic generally to carry out strip using polishing mode or carry out strip using the decoating liquid of Japanese import, the present invention compares polishing mode strip, there is the advantages of mold modification will not be made to damage, and compares import decoating liquid, there is the higher advantage of strip efficiency.
Description
Technical field
The present invention relates to decoating liquid fields, and in particular to a kind of decoating liquid and preparation method thereof of automobile die PVD.
Background technique
Decoating liquid, as the term suggests referring to can be by the one layer of particulate metal or metallics of various platings on the surface of the workpiece
Coating is effectively removed by modes such as immersion, heating, ultrasonic wave, electrolysis, and to workpiece ground without dissolution, it is corrosion-free, non-discolouring
Chemical liquid.
The strip technology in the field automobile die PVD is derived from Japan, and the decoating liquid strip efficiency using Japan is lower, simultaneously
Such decoating liquid itself belongs to hazardous chemical, and there are certain difficulties for import buying, domestic at present not yet to occur being suitable for vapour
The decoating liquid in the field vehicle mold PVD, therefore domestic factory is using mold of polishing as in a manner of main strip, but due to PVD sheet
Body has the physical property of high rigidity, is possible to will cause physical damnification during the grinding process, and mold modification is caused not make again
With.
Summary of the invention
The purpose of the present invention is to provide the decoating liquid and preparation method thereof of automobile die PVD a kind of, which makes
Chemically strip, it is high-efficient, mold modification will not be made to damage.
The technical scheme adopted by the invention is that a kind of decoating liquid of automobile die PVD, the decoating liquid is by following weight
Group is grouped as:
Sodium permanganate 10-30%
Inorganic strong alkali 10-30%
Deionized water 40-80%.
Preferably, the decoating liquid is made of following components by weight percent:
Sodium permanganate 15-25%
Inorganic strong alkali 15-25%
Deionized water 50-70%.
It is highly preferred that the decoating liquid is made of following components by weight percent:
Sodium permanganate 20%
Inorganic strong alkali 20%
Deionized water 60%.
It is highly preferred that the inorganic strong alkali is at least one of sodium hydroxide and potassium hydroxide.
Secondly, the present invention also provides the preparation method of above-mentioned decoating liquid, the preparation method the following steps are included:
(a) potassium permanganate, inorganic strong alkali and deionized water are weighed by the components by weight percent；
(b) deionized water of step (a) described components by weight percent is put into a reservoir；
(c) inorganic strong alkali that step (a) described components by weight percent is put into the deionized water of step (b), forms lye, room
Temperature is placed, and is down to 40 degrees Celsius or less；
(d) into step (c) lye lye investment step (a) described components by weight percent sodium permanganate, stir 40 points
Clock dispenses to get the decoating liquid.
Beneficial effects of the present invention:
Compared with prior art, the operation principle of the present invention is that: sodium permanganate is played under strong basicity or highly acid
Strongest oxidisability, using itself strong oxidizing property on mold chromium, titanium, silicon, aluminium and mixing palladium material strip it is clean.The present invention
Inorganic strong alkali (such as potassium hydroxide) is used to provide strong basicity environment, it is main to carry out strip using sodium permanganate oxidisability.
The present invention do not use potassium permanganate the reason of be potassium permanganate in low temperature, solubility is lower, be easy be precipitated, be not able to maintain compared with
High concentration；Other permanganates are although oxidizing, but stability is poor, it is difficult to save.Compared to other field
Decoating liquid, the sodium permanganate and potassium hydroxide of decoating liquid of the present invention need high level, the sodium permanganate and hydrogen-oxygen of low content
The decoating liquid for changing potassium can not carry out effective strip to automobile die PVD.By testing surface, the present invention compares Japanese import
Decoating liquid strip time-consuming is shorter, more efficient, and since the present invention uses chemical method to handle vapour under alkaline environment
Vehicle mold PVD, therefore mold will not be corroded, physical damnification will not be caused to mold, the mold that strip finishes can continue to use.
