Problems solved by technology

[0003] Existing tinned copper wires often adopt the method of coating the protective layer to improve the fireproof and flame retardant performance of the copper wire. The protective layer will delaminate under burning conditions, which will affect the fireproof efficiency. Based on this, further improvement is needed.

Abstract

The invention discloses a fire-resistant flame-retardant tin-plated copper wire for 5G communication. The fire-resistant flame-retardant tin-plated copper wire comprises the following raw materials in percentage by weight: 20-30 parts of a copper wire substrate, 10-20 parts of a coating agent and 5-10 parts of a sintering material. The preparation method of the coating agent comprises the following steps of: S1, firstly feeding montmorillonite into a rare earth lanthanum chloride solution with the mass fraction of 20-30%, and stirring the mixture for 20-30 minutes, wherein the stirring rotating speed is 100-200r / min. The copper wire substrate is coated by the coating agent, the coating agent is activated and modified by adopting montmorillonite and the rare earth lanthanum chloride solution, and finally, irradiation treatment is performed, so that active energy can be excited, meanwhile, montmorillonite has very high adsorbability and can carry a flame-retardant liquid to be adhered to the copper wire substrate, bentonite in the flame-retardant liquid is of a lamellar structure and can achieve a middle blocking effect, thus external heat of a sintering material is prevented from being in contact with the coating agent, so that a coating layer is prevented from being delaminated, and a very good fireproof effect is achieved.

Description

technical field [0001] The invention relates to the technical field of tinned copper wires, in particular to a fire-resistant and flame-retardant tinned copper wire for 5G communication. Background technique [0002] Copper wire plays a pivotal role in national production. Because of its lower cost than gold and silver and good electrical conductivity, it is widely used in the manufacture of transmission cables for electricity and telecommunications, circuit boards, integrated circuit lead frames, various switches and rectifiers In recent years, tinned copper wires have developed rapidly. Tinned copper wires are mainly used for conductive cores such as rubber insulated mining cables, flexible wires, flexible cables and ship cables. The free sulfur reacts chemically with copper. Tin-plated wires can improve their solderability and avoid false soldering and false soldering during soldering; when tinned copper wires are used as bare wires, they can protect copper wires from ox...
