Problems solved by technology
In order to prevent electromagnetic pollution and information leakage, it is particularly important to control and shield electromagnetic waves. However, when metal fillers are used as conductive fillers, there are disadvantages of high price and heavy coating weight.
[0003] The Ni-Co-La-P, Ni-Co-Fe-La-P and Ni-Fe-La-P quaternary alloy plating solutions and their preparation methods developed by our research group in the early stage can be realized on glass fibers. Shidu, but the loss tangent value at higher frequencies is relatively low, and there is a disadvantage that the conductive glass fiber has weak absorbing performance

Abstract
The invention relates to a Ni-Fe-Nd-P bath and a glass fiber Ni-Fe-Nd-P alloy and a preparation method thereof, which is characterized in that a formula of the bath comprises nickel sulfate, sodium hypophosphite, ferrous sulfate, neodymium nitrate, sodium citrate, malic acid, butane diacid, ammonium sulfate, distilled water, thiourea, urea and concentrated hydrochloric acid; the preparation methodcomprises the following steps: main salts, namely, the nickel sulfate and the ferrous sulfate are put in the distilled water, added with the neodymium nitrate, the distilled water and the concentrated hydrochloric acid after dissolution, and then added with sodium citrate, malic acid, butane diacid, ammonium sulfate, sodium hypophosphite, thiourea and urea in sequence for dissolution and then added with ammonia to prepare the bath. A chemical plating technology is utilized to prepare the glass fiber Ni-Fe-Nd-P alloy. The beneficial effects are that as a right amount of neodymium nitrate is added to the chemical bath, the content of phosphorus in a prepared alloy coating is 5 percent to 10 percent; the glass fiber which adopts the chemical plating has good electrical conductivity and can be used as a conductive filler and an electric loss absorbent.
Description
technical field [0001] The invention relates to a Ni-Fe-Nd-P plating solution, a glass fiber Ni-Fe-Nd-P alloy and a preparation method thereof. Background technique [0002] At present, there are many reports on electroless plating ternary alloy plating solution and its preparation method at home and abroad, and there are few reports on quaternary alloy plating solution and related rare earth element electroless plating, and most of the plating solutions are applied on metal substrates. plating. Generally, when rare earth elements are added, the stability of the plating solution, the deposition rate and the quality of the coating can be significantly improved, and the material can be used to prepare magnetic recording media and corrosion-resistant coatings, but only plating on the metal substrate undoubtedly limits the scope of use of the material. In recent years, various non-metallic materials and polymer materials have been widely used in the electronics industry, and el...
