Problems solved by technology

At present, most of these casings are shielded by adding ultra-fine metal powder, but to make the material have a good shielding effect, the filling amount of the filler to be added needs to be relatively high. Although this type of ultra-fine metal powder is easy to mix, it will also cause The mechanical strength and formability of the shielding material will be affected

Abstract

The invention discloses a polrvinyl chloride material, in particular relating to an inflaming retarding electromagnetic shielding polyvinyl chloride material the mechanical strength of which is improved. The inflaming retarding electromagnetic shielding polyvinyl chloride material comprises the following components in parts by weight: 100-150 parts of polyvinyl chloride, 0.5-5 parts of coupling agent, 20-50 parts of fire retardant, 2-7 parts of metal fiber, 0.2-2 parts of stabilizer, 1-3 parts of colorant and 1-4 parts of lubricant. The inflaming retarding electromagnetic shielding polyvinyl chloride material provided by the invention has good inflaming retarding property and good electromagnetic shielding performance, the oxygen index of the inflaming retarding electromagnetic shielding polyvinyl chloride material is up to above 32.7, the electromagnetic shielding effect of the inflaming retarding electromagnetic shielding polyvinyl chloride material under the condition of 30 MHz-1500MHz can reach above 62 dB, thereby meeting the requirements on insulation and electromagnetic shielding. According to the production method of the inflaming retarding electromagnetic shielding polyvinyl chloride material, hybrid molding can be carried out on the metal fiber and other materials conveniently, which is completed just by using the existing equipment.

Description

technical field [0001] The invention relates to a polyvinyl chloride material, in particular to a flame-retardant electromagnetic shielding polyvinyl chloride material. In addition, the invention also relates to a production method of polyvinyl chloride material, especially a production method of flame-retardant electromagnetic shielding polyvinyl chloride material. The invention also relates to a bushing, especially an electrical bushing. Background technique [0002] In recent decades, with the popularization of various electrical appliances and the wide application of electronic computers, communication satellites, high-voltage transmission grids and some medical equipment, the interference of electromagnetic waves has become more and more serious. For this reason, electromagnetic shielding treatment is required. At present, most of these casings are shielded by adding ultra-fine metal powder, but to make the material have a good shielding effect, the filling amount of ...
