Efficient scaling powder and preparing method thereof

Abstract

The invention discloses efficient scaling powder and a preparing method thereof. The efficient scaling powder is made of raw materials including polyacrylic acid, succinic acid, salicylic acid, 2-ethylhexyl epoxystearate, n-dodecanol ester, modified rosin, benzotriazole, benzimidazole, acrylic vinegar, acrylonitrile, benzyl alcohol, cyclohexanol, ethyl alcohol, a surface active agent, an antioxidant, nanosilicon dioxide, nano titanium dioxide and deionized water. The scaling powder is high in activity, the welding aid property is excellent, after welding, solid object is small in residue, cleaning is easy, the surface of a welded base body is transparent, clean and free of mark, the preparing method is simple, implementation is easy, and the powder is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of metal processing aids, in particular to a high-efficiency soldering flux and a preparation method thereof. Background technique [0002] With the continuous development of electronic technology and the increasing popularity of integrated circuit applications, flux plays an increasingly important role in the electronics industry and related industries. In modern industrial production, flux is used more and more widely. Flux It is a substance with chemical and physical activation properties, which can remove oxides on the surface of the metal to be welded or other formed surface films and oxides formed on the outer surface of the solder itself, so that the surface to be welded can be stained with tin and For the purpose of soldering, the function of flux can also protect the metal surface, so that it will not be re-oxidized in the high-temperature environment of welding, and at the same time can reduce the ...

Problems solved by technology

[0003] There are many types of flux, which can be roughly divided into three series: organic, inorganic and resin; resin flux is usually extracted from the secretions of trees, which is a natural product and is not corrosive. Rosin is the representative of this type of flux, so Also known as rosin-based flux; flux is usually a mixture of rosin as the main component, which is an auxiliary material to ensure the smooth progress of the welding process. To achieve the necessary cleanliness, it prevents re-oxidation of the surface during soldering, reduces the surface tension of the solder, improves soldering performance, and the performance of the flux directly affects the quality of electronic products. Traditional flux is composed of ordinary rosin, flux and Composed of organic solvents, etc., it is easy to cause problems such as low insulation resistance after welding, easy leakage risk, and environmental pollution.
