Problems solved by technology

If the transparent electrical casing is not bent, it is necessary to use pipe fittings such as large arc elbows or 90° elbows to make transition connections at the corners. The pipes need to be cut and connected to the pipes many times. It is easy to cause waste and increase the construction cost
Therefore, the transparent electrical bushing is generally processed by inserting springs and then bending at the corner, but the transparent electrical bushing is prone to whitening after bending, which affects the appearance and performance of the transparent electrical bushing

Abstract

The invention discloses a transparent electrical casing pipe capable of penetrating through a spring and being bent without being whitened and a preparation method of the transparent electrical casingpipe. The electrical casing pipe is prepared from polyvinyl chloride resin, an organic tin stabilizer, dioctyl phthalate, a methyl methacrylate / styrene / butadiene styrene rubber terpolymer, a methyl methacrylate / acrylate copolymer, an antioxidant, an external lubricant, an ultraviolet light absorber and a pigment according to a certain ratio. The preparation method comprises the following steps: uniformly mixing the raw materials, adding the mixture into a twin-screw extruder, setting the temperature of a machine barrel to be 140-155 DEG C, the temperature of a confluence core to be 140-150 DEG C, the temperature of a template to be 160-170 DEG C and the temperature of a neck mold to be 180-190 DEG C, and cooling and shaping after extrusion molding is finished. The electrical casing pipe cannot be whitened after being bent after being inserted into the spring, and other performances are not affected. The preparation method of the electrical casing pipe is simple, convenient to operateand low in preparation cost.

Description

technical field [0001] The invention relates to the technical field of preparation of electrical bushings, in particular to a transparent electrical bushing that is bent through a spring without turning white and a preparation method thereof. Background technique [0002] During use, the transparent electrical bushing needs to be bent through a spring to make a turn when it hits a wall. If the transparent electrical casing is not bent, it is necessary to use pipe fittings such as large arc elbows or 90° elbows to make transition connections at the corners. The pipes need to be cut and connected to the pipes many times. It is easy to cause waste and increase construction costs. Therefore, the transparent electrical bushing is generally processed by inserting springs and then bending at the corner, but the transparent electrical bushing is prone to whitening after bending, which affects the appearance and performance of the transparent electrical bushing.
