Problems solved by technology

[0003] Traditional PVC-U electrical bushings, in the formulation design process, add a lot of calcium carbonate fillers and additives that affect the transparency of the product, and do not do special treatment in the mixing and molding process, resulting in the prepared electrical bushings being opaque If the internal wires or cables cannot be seen, it is not easy to thread the wires during the installation process, and it is inevitable that the wires will be knotted during the wire laying process, resulting in increased resistance, poor contact or leakage at the joints, accidental damage to the wire insulation layer, etc. All kinds of problems are difficult to find and repair, the difficulty and time of acceptance increase, and even cause hidden troubles to the line

Abstract

The invention discloses a transparent PVC-U (unplasticized polyvinyl chloride) electrical conduit. The transparent PVC-U electrical conduit is prepared from the following raw materials in parts by mass: 100 parts of polyvinyl chloride resin, 1.0 to 5.0 parts of heat stabilizer, 0.2 to 3.0 parts of internal lubricant, 0.1 to 1.5 parts of external lubricant, 0.2 to 3.0 parts of processing modifier, 1 to 10 parts of flexibilizer, 0.511 to 0.680 parts of pigment, 0 to 1.5 parts of antioxidant and 0.1 to 0.8 part of light stabilizer. The invention also discloses a preparation method of the composition. The PVC-U electrical conduit has the advantages of being good in visualization and traceability, hidden danger searching is convenient, and a user can conveniently achieve project quality self-inspection. In addition, the PVC-U electrical conduit has outstanding environmental protection, bending, impact resistance, flame retardance, insulating property and the like.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a method for preparing a transparent PVC-U electrical sleeve. Background technique [0002] In the field of engineering and home improvement, in order to protect and ensure the safety of electricity use, wires or cables should be arranged in flame-retardant and insulated electrical casings, and the laying direction of wires or cables should be horizontal and vertical, and fixed firmly. [0003] Traditional PVC-U electrical bushings, in the formulation design process, add a lot of calcium carbonate fillers and additives that affect the transparency of the product, and do not do special treatment in the mixing and molding process, resulting in the prepared electrical bushings being opaque If the internal wires or cables cannot be seen, it is difficult to thread the wires during the installation process, and it is inevitable that the wires will be knotted during the wire layin...
