Abstract

The invention discloses a preparation method a flexible PVC (polyvinyl chloride) terminal bushing with heat conduction and insulation properties. Firstly, 100 parts by mass of PVC, 48-52 parts by mass of a compound plasticizer, 1-3 parts by mass of a stabilizer and 5-10 parts by mass of modified aluminum nitride are mixed uniformly, vacuumized and filtered, and a PVC plastic dipping fluid is prepared; a terminal bushing mold is preheated to 180-220 DEG C, then dipped into the plastic dipping fluid and taken out after 3-50 seconds; the mold with the plastic dipping fluid is gelatinized at 220-300 DEG C for 10-30 seconds, taken out and put in a cooling liquid to be cooled for 8-25 seconds, and the terminal bushing is obtained after being demolded with an air gun. With the adoption of a plastic dipping process, the formation cycle is short, no welded seams are formed, and the product has the heat conduction and insulation properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and specifically designs a PVC heat-conducting insulating terminal sleeve and a preparation method thereof. Background technique [0002] PVC was once the largest general-purpose plastic in the world, and it is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. Soft PVC products are widely used in the field of electronic insulating terminal sleeves due to their simple molding process, excellent insulation performance and flame retardancy. However, with the development of the electronics industry, ordinary insulated terminal sleeves can no longer meet the requirements of use, especially in occasions that require both heat conduction and insulation, such as thermistor terminals. Therefore, it is o...
