Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions of each exemplary embodiment provided in the present application with reference to the accompanying drawings in the embodiments of the present application. In the case of no conflict, the following embodiments and technical features thereof can be combined with each other.

[0025] The application provides a hot melt adhesive, which is made by mixing aliphatic polyamide, polyethylene wax, antioxidant, maleic anhydride grafted polyolefin and polyvinyl alcohol.

[0026] For aliphatic polyamides, polyamides are commonly known as nylon (Nylon), the English name Polyamide (abbreviated as PA), and the density is 1.15g / cm3. Family PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application. The softening point of the aliphatic polyamide in the examples of the present application is 90-140°C, the melting temperature is 120-170°C, and the mel...

Abstract

The invention discloses a hot melt adhesive, a preparation method thereof and a wire head insulation method. The hot melt adhesive is prepared by mixing aliphatic polyamide, polyethylene wax, an antioxidant, maleic anhydride grafted polyolefin and polyvinyl alcohol. The hot melt adhesive has proper bonding strength with the surfaces of a copper wire and soldering tin, can ensure that a wire head does not fall off in the transportation vibration process after being insulated, and can be easily peeled off without residues in the welding process of the wire head, so that the welding effect of the wire head is not influenced, and in addition, the hot melt adhesive is relatively environment-friendly, relatively high in insulating property and reliability, and has no adverse effect on the lead head and an electronic product welded with the lead head.

Description

technical field [0001] The present application relates to the technical field of wire head insulation, in particular to a hot melt adhesive, a preparation method thereof, and a wire head insulation method. Background technique [0002] At present, with the vigorous development of small electronic products such as telephone watches, electronic cigarettes, wireless earphones, wireless mice, etc., the application of small batteries is becoming more and more extensive. Many applications. However, since one end of the wire is connected to the positive and negative poles of the battery management system, and the other end is exposed in the non-fixed battery storage tray, it is very easy to contact foreign objects or adjacent conductors when the battery is transported from the battery manufacturer to the host. Direct electrical connection causes a short circuit problem, so that the existing outgoing batteries must be insulated on the exposed wires before shipment. [0003] There ...
