Cable sheath material with mildew-proof function and preparation method thereof

Abstract

The invention belongs to the technical field of electric materials and provides a cable sheath material with mildew-proof function and a preparation method thereof. The cable sheath material with mildew-proof function is prepared from the following raw materials in parts by weight: 52 to 61 parts of chloroprene rubber, 3 to 9 parts of bisphenol A epoxy resin, 4 to 5 parts of o-phenyl phenol, 1 to 3 parts of a plasticizer, 3 to 8 parts of a vulcanizing agent, 1.3 to 3.2 parts of a reinforcing agent, 1 to 3 parts of a Chinese medicinal herb antibacterial agent, 1 to 4 parts of antimony trioxide, 2 to 5 parts of a smoke eliminating agent, 0.9 to 2.5 parts of gamma-aminopropyltriethoxysilane and 9 to 15 parts of chitin. According to a formula of the cable sheath material, the Chinese medicinal herb antibacterial agent and chitin are added and have an inhibition effect on growth and proliferation of microorganisms including bacteria, mildew and the like, so that the invasion, caused by microorganisms, on the cable sheath material is reduced and the cable sheath material is prevented from mildewing; and skin color change or worsening of the cable sheath material is prevented, so that the performance of a cable is ensured.

Description

technical field [0001] The invention belongs to the technical field of electric power materials, and in particular relates to a cable sheathing material with anti-mildew function and a preparation method thereof. Background technique [0002] During the long-term use of the cable, its mechanical properties, electrical properties and other properties gradually deteriorate, which eventually leads to the loss of use value, which is called aging phenomenon. Factors that cause aging include physical, chemical and biological factors. For the aging caused by physical factors and chemical factors, the current research is relatively mature, and many practical methods have been proposed to prolong the service life of cables. However, there are few studies on aging caused by biological factors. [0003] Aging caused by biological factors includes corrosion of cables by bacteria, molds, etc., especially microorganisms such as bacteria, molds, and actinomycetes. This kind of microorga...

AI Technical Summary

Problems solved by technology

The reproduction of microorganisms will inevitably lead to mold spots on the surface of the sheath, which will cause the surface of the cable to change color or deteriorate, and the printing will become blurred, thus affecting the normal use of the cable

Because microorganisms use organic matter as their food source, the loss of organic matter in the sheath will eventually lead to a decline in its mechanical and electrical properties, thereby shortening the service life of the cable, causing waste of resources, and causing damage to environmental sanitation
