Problems solved by technology

Polyethylene and cross-linked polyethylene are modified materials based on polyethylene resin. Polyethylene resin is non-polar and has good electrical tracking resistance. At present, the invention and research of electrical tracking-resistant polyethylene sheath materials are also Many, such as a high tracking resistance ADSS cable sheath material (patent number: CN104151681A), but the research on the resistance to tracking of polyvinyl chloride insulating materials is rarely reported
Moreover, the PVC insulating material for overhead cables currently on the market can only withstand 1 hour at a voltage of 1.5KV according to GB / T6553-2014, and the resistance to electric tracking is particularly poor.

Abstract

The invention discloses a tracking-resistant polyvinyl chloride insulating material, and a preparation method and an application thereof. The tracking-resistant polyvinyl chloride insulating materialcomprises, by weight, 80-100 parts of polyvinyl chloride resin, 40-70 parts of a plasticizer, 10-20 parts of nanoscale activated calcium carbonate, 30-80 parts of a tracking-resistant modifier, 6-8 parts of a heat stabilizer, 1-1.8 parts of a light stabilizer, 2-3 parts of an ultraviolet light absorber and 10-20 parts of an electrical property modifier. The tracking resistance of the tracking-resistant polyvinyl chloride insulating material is effectively improved on the basis of meeting all requirements of the polyvinyl chloride insulating material in GB / T12527-2008, so the insulating material can pass through 1A2.5-level tracking resistance tests (according to GB / T6553-2014), the service life of a polyvinyl chloride insulated overhead cable is prolonged, and the safety of an overhead power transmission line is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cable sheathing materials, specifically discloses a tracking-resistant polyvinyl chloride insulating material and a preparation method thereof, and discloses that the tracking-resistant polyvinyl chloride insulating material is used in the field of overhead insulated cables with a rated voltage of 1KV and below Applications. Background technique [0002] In recent years, my country's economy has developed rapidly, especially the power industry, which is the lifeblood of the country's economy, has developed rapidly. Among them, the safety of overhead transmission lines has attracted widespread attention. As the name suggests, overhead wires are laid in the air. During operation, they will inevitably be affected by various factors such as temperature, electricity, mechanical stress and vibration, sun exposure, harmful gases, chemicals, moisture, dust, etc. With the continuation of the running time, the ins...
