Abstract
The invention discloses electroplating liquid with good stability. The electroplating liquid with good stability comprises a dispersant, a water reducing agent and a silane coupling agent, wherein the dispersant is sodium dodecyl sulfate, the water reducing agent is polycarboxylic acid, the silane coupling agent is butadiene triethoxy silane, the sodium dodecyl sulfate accounts for 35-45% of the total weight of the electroplating liquid with good stability, the polycarboxylic acid accounts for 22-33% of the total weight of the electroplating liquid with good stability, and the butadiene triethoxy silane accounts for 30-36% of the total weight of the electroplating liquid with good stability. The electroplating liquid with good stability, provided by the invention, has the advantages of good stability, excellent uniform coverage ability and high electroplating speed.
Description
Technical field
The present invention relates to a kind of electroplate liquid, relate in particular to a kind of electroplate liquid of good stability.
Background technology
In mechanical processing process, the antirust grease that component surface adheres to, cutting fluid, machinery oil, lubricating grease, grinding fluid, releasing agent etc. mix and stick together with dust, polishing dust, form thicker dirt.If, not by above soil release, after its quenching sinters obstinate solid grease into, degreasing and rust removal is difficult to clean up before thermal treatment, during plating, bubble adheres to and on it, makes coating form gas hold-up type pin hole.Heat treated part surface inevitably can adhere to one deck greasy dirt, when dust falls from the teeth outwards, and sticks together with grease is mixed, of long duration is difficult to clean up, thereby makes workpiece surface form unconspicuous tiny oil mark, and during plating, bubble is detained formation pin hole it on.While adopting in addition mesh band type resistor furnace to quench; the impurity particles such as the greasy dirt of workpiece surface and dust are mixed to stick together; sinter obstinate solid grease into; during salt made from earth containing a comparatively high percentage of sodium chloride tempering; above grease again with the thermopolymer of nitro salt formation stubbornness; during plating, be difficult to the thorough Ex-all of above dirt; bubble hydrogen easily sticks to above dirt; be difficult to discharge, thereby make coating produce pin hole and pit phenomenon, and along with bubble is grown up gradually; coating can burst automatically; produce decortication phenomenon, thereby a little less than causing electroplate liquid poor stability, covering power, electroplating velocity is shortcoming slowly.
Summary of the invention
The invention provides a kind of covering power with good stability, excellence, the electroplate liquid of the good stability of the high advantage of electroplating velocity.
Technical scheme of the present invention is: a kind of electroplate liquid of good stability, the electroplate liquid of described good stability comprises dispersion agent, water reducer and silane coupling agent combine, described dispersion agent is sodium lauryl sulphate, described water reducer is poly carboxylic acid, described silane coupling agent is butadienyl triethoxyl silane, described sodium lauryl sulphate accounts for the 35%-45% of the overall component of electroplate liquid of good stability, described poly carboxylic acid accounts for the 22%-33% of the overall component of electroplate liquid of good stability, described butadienyl triethoxyl silane accounts for the 30%-36% of the overall component of electroplate liquid of good stability.
In a preferred embodiment of the present invention, described sodium lauryl sulphate comprises lauryl alcohol and sodium sulfate.
In a preferred embodiment of the present invention, described sodium lauryl sulphate account for good stability the overall component of electroplate liquid 38%, described poly carboxylic acid account for good stability the overall component of electroplate liquid 28%, described butadienyl triethoxyl silane account for good stability the overall component of electroplate liquid 34%.
The electroplate liquid of a kind of good stability of the present invention, has good stability, excellent covering power, the advantage that electroplating velocity is high.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Wherein, the electroplate liquid of described good stability comprises dispersion agent, water reducer and silane coupling agent combine, described dispersion agent is sodium lauryl sulphate, described water reducer is poly carboxylic acid, described silane coupling agent is butadienyl triethoxyl silane, described sodium lauryl sulphate accounts for the 35%-45% of the overall component of electroplate liquid of good stability, described poly carboxylic acid accounts for the 22%-33% of the overall component of electroplate liquid of good stability, described butadienyl triethoxyl silane accounts for the 30%-36% of the overall component of electroplate liquid of good stability, described sodium lauryl sulphate comprises lauryl alcohol and sodium sulfate.
Further illustrate, described sodium lauryl sulphate account for good stability the overall component of electroplate liquid 38%, described poly carboxylic acid account for good stability the overall component of electroplate liquid 28%, described butadienyl triethoxyl silane account for good stability the overall component of electroplate liquid 34%.Sodium lauryl sulphate performance: white or faint yellow powdery, water-soluble, insensitive to alkali and hard water.There is decontamination, emulsification and excellent foaming power.It is a kind of nontoxic anion surfactant.Its biological degradability >90%.Purposes: as emulsifying agent, fire-fighting medium, whipping agent and textile auxiliary agent.Also be used as the whipping agent of toothpaste and paste, powdery, shampoo.
Further illustrating, polycarboxylic admixture, there is lignin sulfonate admixture, naphthalene sulfonic salt formaldehyde condensation products, melamino-formaldehyde polycondensate, acetone sulfonate and formaldehyde condenses, sulfamate formaldehyde condensation products etc., these products have certain advantage and the adaptability to high silt contents of material such as sandstones on cost, Gu there is very large occupation rate on market, have utilization in various degree in concrete works.
Further illustrating, butadienyl triethoxyl silane can make the pull strength of silicon rubber and metal reach 21.6～22.4 kilograms per centimeter 2.General caking agent or resin can not only improve bond strength after being used in conjunction with coupling agent, and main is water tolerance and the weather resistance that increases bounding force.Although as polyurethane(s) and epoxy resin have high bounding force to many materials, bonding weather resistance and water tolerance are not ideal; Add after silane coupling agent, the performance of this respect can be significantly improved.The invention provides a kind of electroplate liquid of good stability, there is the covering power of good stability, excellence, the advantage that electroplating velocity is high.
The specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
