Rat-proof polyvinyl chloride (PVC) cable material and preparation method thereof

Abstract

The invention belongs to the field of a cable material, and particularly relates to a rat-proof polyvinyl chloride (PVC) cable material. The rat-proof PVC cable material is prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 6-10 parts of an impact modifier, 40-45 parts of a plasticizer, 0.1-0.5 parts of an antioxidant, 0.1-0.5 parts of a lubricating agent, 5-8 parts of a heat stabilizer, 20-30 parts of a filler, 15-20 parts of a fire retardant and 2-3 parts of raticide. The PVC cable material provided by the invention has excellent mechanical and physical properties, and can meet the rat requirements of the cable, and the protection rate can be up to over 99.5%.

Description

technical field [0001] The invention belongs to the field of cable materials, and in particular relates to a rat-proof PVC cable material and a preparation method thereof. Background technique [0002] In modern society, wires and cables can be seen everywhere, such as wires and broadband access lines used in homes and hotels; power cables and overhead cables laid by power departments, etc. Wires and cables play a very important role in national economy and social activities. status. With the rapid development of the economy, the wire and cable industry has become the second largest industry in my country. Rats are one of the three major hazards that endanger plastic cables and optical cables. They cause many accidents every year and cause huge economic losses. Therefore, it is very necessary to carry out research on recycled rat-proof sheathing materials. [0003] In the past, anti-rodent agents were added to the plastic materials of cable sheaths, such as cycloheximide, ...

AI Technical Summary

Problems solved by technology

[0003] In the past, anti-rodent agents were added to the plastic materials of cable sheaths, such as cycloheximide, terpenoid monomers, etc., mostly for "poisonous killing". The result of poisonous "lose-lose" does not meet the requirements of environmental protection. At the same time, the addition of such rodent repellent also reduces the performance of cable materials, which is also one of the problems that need to be solved.
