Abstract

The invention provides a transparent electrical bushing which is characterized by being prepared from the following components in parts by weight: 100 parts of polyvinyl chloride, 1.0-2.0 parts of anorganic tin stabilizer, 0.6-1.6 parts of an internal lubricant, 0.2-2.0 parts of an external lubricant, 1.0-2.0 parts of a processing aid, 3.0-6.0 parts of a modifier, 1.0-1.5 parts of DOP, 0.2-1 partof a pigment and 0.002-0.006 part of a whitening agent. The pipe has a relative density of 1.35 to 1.55 and is high in corrosion resistance, which is 1.5 to 2 times that of conventional pipes, and good in transparency; the surface and the inner wall of the PVC wire pipe are smooth and have no concavo-convex sense, and the smooth inner wall greatly reduces the resistance when a wire is pulled; theperformance is 2 to 2.5 times that of the conventional pipes. The transparent electrical bushing emits green smoke when burned, has a high flame retardant coefficient and does not produce a pungent odor.

Description

technical field

[0001] The invention belongs to the technical field of pipes and relates to a transparent electrical sleeve. Background technique

[0002] With the improvement of living standards, the level of decoration is getting higher and higher. One of the key points of decoration is line installation. There are two main modes of existing line installation, one is the interior wall line, and the other is the exterior wall line. , and in order to facilitate maintenance, most of them will use external wall wires, and the external wall wires use a flame-retardant outer sleeve to protect the wire group to form a concealed circuit structure.

[0003] Most of the existing circuit concealment structures use opaque plastic materials to make flame-retardant outer sleeves. When there is a problem with the line, it is necessary to use a test pen to overhaul section by section, which greatly consumes the time for overhaul. For some lines that are about to age It cannot be discover...
