Embodiment 1

[0024] In this embodiment, the components of the PVC impregnation solution for the insulating sheath of copper bars are composed as follows in parts by mass:

[0025]

[0026] The above raw materials are evenly mixed according to the proportion, and then the PVC impregnating liquid for copper bar insulation sheath can be prepared.

[0027] In the present embodiment, the dipping process of the PVC dipping solution for the insulating sheath of the copper row is as follows:

[0028] 1. Fix the copper bar on the fixture after protective bandaging treatment, start the automatic cycle of the machine, and preheat for 300s at the furnace temperature of 280°C;

[0029] 2. Immerse the preheated copper bar into the PVC dipping solution prepared in this example, so that the dipping solution evenly wraps the copper bar; the copper bar first drops by 30mm at a speed of 350mm / min, and then drops by 35mm at a speed of 100mm / min. The time is 15s; then the copper bar rises by 30mm at a spee...

Abstract

The invention discloses a polyvinyl chloride (PVC) impregnating solution for copper bar insulation sheaths, and an impregnation processing technology of the PVC impregnating solution. The PVC impregnating solution is prepared by mixing PVC resin, a stabilizing agent, a flame retardant, a compound plasticizer, a viscosity reducer and filler; after copper bars are impregnated and cured by using thePVC impregnating solution, the PVC copper bar insulation sheaths can be obtained. The PVC copper bar insulation sheaths are excellent in insulating property, high-temperature-resistant, good in flame-retardant property and long in service life.

Description

technical field [0001] The invention relates to a method for insulating a copper bar, in particular to a PVC dipping liquid for a copper bar insulating sheath and a dipping process thereof. Background technique [0002] Copper bar insulation treatment methods mainly include epoxy resin spraying (dipping powder), heat shrinkable sleeve, encapsulation (injection molding), etc. Epoxy resin spraying (dipping powder) is to place the preheated copper bar in the fluidized bed of epoxy encapsulation material, and apply epoxy encapsulation material to the surface of the copper bar. This kind of insulating sheath is brittle and is mostly used In a static environment, when used on a car, due to shaking, it is easy to cause the envelope to crack and fall off in pieces; the insulation sheath of the heat shrinkable sleeve cannot meet the complex shape of the copper bar, and it is easy to deform and accumulate when the temperature is slightly higher , and poor weather resistance, easy to ...
