Abstract
Disclose a kind of being exclusively used in when electroplating, the non-surfacing of plating piece is imposed the preparation of the insulation compound of insulation protection.It is that nylon-66/6/M * D-10 is dissolved in the ethanol; and with the molybdenum disulphide powder uniform mixing; form latex shape fluid; with hairbrush it is brushed on the non-surfacing of plating piece; drying promptly becomes that bonding force is strong, insulativity reliable, have excellent toughness and hardness, collided, rub or meet situation uneven in temperature can not absolve the insulating protective coating that peels off yet after the curing; still very stable, reliable in its every performance below 100 ℃, can satisfy the various galvanized occasion of heating known today fully.Can soak again after the plating to be dissolved in the ethanol and remove totally with hairbrush.
Description
The present invention relates to high molecular polymer is dissolved in the preparation of the method, particularly a kind of isolative painting for electroplating of preparation new coating in the solvent.
Do not see as yet in the market to be exclusively used in when electroplating, can impose insulation protection to the non-surfacing of plating piece, electroplate and to remove the insulation compound that totally and not damages plating piece easily again after finishing.Traditional insulation protection measure to the non-surfacing of plating piece after more commonly the mineral tallow heating being dissolved, is dipped in plating piece wherein again; then put forward to make and be sticked and coated on the lip-deep mineral tallow of plating piece cooled and solidified in air; scraping is electroplated the mineral tallow of facial position, and metal covering is exposed, and just begins to electroplate.This insulation protection mode is constructed and is very bothered, and the mineral tallow of after plating finishes agglutinated on the non-surfacing of plating piece is difficult to removing totally, and is careless slightly; the surface of easy damaged plating piece also the most inconsiderablely is this method can not be used to the to heat occasion of plating; unless, generally all be reluctant to adopt so have no alternative but.When need were heated plating, when for example using special-purpose plating bath chromium plating, great majority were to adopt the non-surfacing brushing of plating piece insullac is carried out insulation protection at present.This method is the cost height not only, and insullac does the back and meet the easy embrittlement exoneration of thermal capacitance, and the bath corrosion that the slight crack place still can be infiltrated and non-surfacing is damaged electroplates that to finish the back also very difficult to the cleaning of insulation enamelled coating; Also the someone takes to bind insulation paper or plastics film etc. at the non-surfacing position of plating piece, imposes insulation protection with the non-surfacing to plating piece, because this method is difficult to accomplish tight sealing, in the very easy infiltration parcel of the plating bath face, its insulation protection effect is poorer.
The present invention can provide a kind of to the public and can be applicable to plating occasion that temperature is higher and reliable for effectly with plating piece bonding strength height, insulation protection, not only convenient apply, but also remove the preparation that totally, does not damage plating piece, plating special isolation coating that production cost is low easily.
Now its principle and specific embodiments are described below:
Nylon-66/6/M * D-10 itself is exactly a kind of good insulating material, especially it dissolves among the organic solvents such as ethanol, form the latex shape, it is coated on the plating piece surface, after treating solvent evaporates, promptly condensing becomes one deck even compact, the insulation layer of embrittlement deformation not in plating environment below 100 ℃, suitably sneak into some molybdenumdisulphide powder therein, this insulation layer is more rub resistance, anti-collision just.
Its prescription is, (by weight percentage), and in per 100 gram coating,
Granular nylon-66/6/M * D-10 accounts for 19.5～20.5,
Powdery molybdenumdisulphide accounts for 0.5～0.7
All the other are 83～88% ethanol for purity;
To be loaded in the airtight container by above-mentioned prescription confected materials, under 60～80 ℃ of conditions, keep 30～60 minutes, during also can be stirred, granular nylon-66/6/M * D-10 is dissolved fully, and with the molybdenum disulphide powder uniform mixing.
Using method is that the insulation compound that will prepare is successively brushed equably at plating piece and need be immersed on the non-surfacing at position in the plating bath, until the coat that presents black, place 140～150 ℃ interior the curing one hour of baker after drying again, take out behind the furnace cooling, this coat promptly form insulativity reliable, have good toughness and hardness, collided, also can not absolve the insulating coating that peels off under friction or the situation uneven in temperature.Still very stable, reliable in its every performance below 100 ℃, can satisfy the galvanized occasion of heating known today fully, the needs of plating piece insulation protection during for example with special efficient plating bath rapid chrome plating.After plating finished, as long as the position that is applying this insulation compound in the plating piece is dipped in the ethanol, insulating coating just can be dissolved, the plating piece surface can be cleaned with water clean and do not have any damage with hairbrush.
