Abstract

The invention discloses an environment-friendly modified polyvinyl chloride tight buffering material for a soft communication optical cable and a preparation method of the material. The material comprises the following raw materials in parts by weight: 95-100 parts of polyvinyl chloride resin, 30-35 parts of an environment-friendly plasticizer, 5-8 parts of a cold-resistant plasticizer, 5-8 parts of an environment-friendly stabilizer, 20-35 parts of a filling agent, 3-8 parts of a flame retardant, 0.5-2 parts of a lubricant, 4-9 parts of an anti-impact modifier and 3-5 parts of an anti-heat shrinkage modifier. Due to the addition of the cold-resistant plasticizer, the material is outstanding in high temperature resistance, low temperature resistance and environmental protection property; due to the anti-heat shrinkage modifier, the material is relatively low in heat shrinkage rate; due to the flame retardant, the material is relatively good in flame retardant property. According to the preparation method, the process is simple, the temperature is reasonable, and the produced material is guaranteed to be relatively good in flame retardant property, high and low temperature resistance and small in heat shrinkage rate.

Description

technical field [0001] The invention belongs to the field of tight sleeve optical cable materials, and in particular relates to an environmentally friendly modified polyvinyl chloride tight sleeve material for communication flexible optical cables and a preparation method thereof. Background technique [0002] Fiber To The Home (FTTH) and Fiber To The Desk (FTTD) are the development trend of optical communication and the symbol of the development of information society. With the rapid development of broadband technology and intelligent buildings, the market demand for indoor optical cables has increased significantly. Indoor optical cables are generally composed of two parts: the core and the sheath. If the indoor optical cable uses a tight jacket material, it can protect the fiber core well and maintain good signal transmission performance. At present, the sheath materials that can be used as tight sleeve layer mainly include polyvinyl chloride (PVC), nylon, thermoplastic...
