Problems solved by technology

However, the organic amine hydrohalide in the above-mentioned flux plays a vital role in the activity of the flux. If it is missing, the fusing speed of the fusible alloy wire will slow down, and even the phenomenon of continuous disconnection after melting may occur.

Abstract

The invention discloses a fluxing agent as well as a preparation method and application thereof. The fluxing agent comprises the following components in percentage by weight: 60-80 percent of rosin, 2-20 percent of organic acid and 10-30 percent of octadecanamide. The fluxing agent can be applied to temperature fuse elements to promote the fusing of a fusible ally wire. Compared with the prior art, the fluxing agent does not contain halogen and accords with the development tendency of environment protection. When applied to temperature fuse, the fluxing agent can achieve the effect of using a fluxing agent containing halogen.

Description

technical field [0001] The invention relates to a flux, in particular to a halogen-free flux for a temperature fuse. Background technique [0002] People are paying more and more attention to the safety of electronic and electrical equipment, requiring these equipment to be equipped with over-temperature and over-current protection devices. At present, thermal fuses are commonly used over-temperature protection components. [0003] The main part of the thermal fuse is a fusible alloy wire. When the ambient temperature rises to the melting point of the fusible alloy, the fusible alloy wire melts and disconnects, thereby cutting off the circuit protection device. Therefore, whether the fusible alloy wire can be completely disconnected in time is the key technology of the thermal fuse. In order to improve the fusibility of the fusible alloy wire, it is common practice to wrap flux around the fusible alloy wire. The main component of the flux is rosin, including natural rosin...
