Problems solved by technology

[0004] Under the premise of the rapid development of the market economy, the improvement of enterprise production efficiency and the control of production costs have become the main factors for the current enterprise development, while the drawing speed of ordinary insulating materials (100-200 m / min) can no longer meet the market demand. Therefore, it is necessary to improve the material to further increase the wire drawing speed

Abstract

The invention discloses a high humidity tolerance, high electric performance and environment-friendly polyvinyl chloride (PVC) insulation material for electric wires and cables. The PVC insulation material is prepared by the following components by weight: 100 parts of PVC resin powder, 40 to 60 parts of a plasticizer, 4 to 6 parts of epoxy soybean oil, 5 to 8 parts of an environment-friendly stabilizing agent, 0.4 to 0.8 part of a lubricant, 5 to 40 parts of an electric performance modifier, 4 to 8 parts of a fire retardant, 0.4 to 1 part of inhibitor 1024, 0.3 to 0.6 part of the anti-oxidant AO-50 and 0.4 to 1 part of a rheological agent. The PVC insulation material for electric wires and cables in the invention, prepared by adopting a special raw material ratio, not only has excellent high humidity tolerance and high electric performance, but also enables a wire drawing speed of the material to be improved and environmental protection to be obtained. The PVC insulation material is applicable to wires used in temperature transmission devices for air-conditioners or to power lines, data lines or the like used in other high humidity environments.

Description

technical field [0001] The invention relates to an insulating material for wires and cables, in particular to a high-humidity, high-electricity and environment-friendly polyvinyl chloride insulating material for wires and cables. Background technique [0002] Traditional PVC wire and cable materials contain harmful substances such as (P6), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr) heavy metal elements, polybrominated biphenyls and their ethers, o-benzenes, short-chain chlorinated paraffins, and Containing phthalic plasticizers will produce secondary pollution after burning, affecting human health and the ecological environment. [0003] At present, the temperature infectious device wires for air conditioners on the market are used in high temperature and high humidity, due to their insufficient insulation capacity, which affects the weather resistance and service life of the temperature sensor. Tests have shown that the existing polyvinyl chloride insulating mate...
