Flame-retardant plastic-steel cable sheathing material and preparation method thereof

Abstract

The invention provides a flame-retardant plastic-steel cable sheathing material, and relates to the technical field of cable processing. The sheathing material is prepared from the following raw materials in parts by weight: 150-250 parts of polyvinyl chloride resin, 150-250 parts of dioctyl phthalate, 6-8 parts of plasticizer, 15-25 parts of acrylic resin, 15-17 parts of cellulosic fibers, 6-8 parts of aluminum hydroxide, 8-10 parts of magnesium hydroxide, 12-14 parts of cerussite, 15-25 parts of modified kaolin, 10-20 parts of talc powder, 10-20 parts of calcium carbonate, 15-25 parts of zinc stearate, 2-4 parts of an antiaging agent NBC and 6-8 parts of an antiaging agent MB. The preparation method has the beneficial effects of concise process flow, reasonable raw material proportion, low-price and easily-available raw materials and simple processing, the sheathing material is prepared from a plastic-steel material, the constant strength of the sheath can be ensured, and the flame-proofing and high-temperature-resistance performance of the sheath can be ensured. The flame-retardant plastic-steel cable sheathing material is suitable for high-temperature regions, and is convenient for popularization and application.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a flame-retardant plastic-steel cable sheath material and a preparation method thereof. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. The continuous and rapid growth of China's economy has provided a huge market space for cable products. The strong temptation of the Chinese market has made the world focus on the Chinese market. In just a few decades of reform and opening up, China's ...

Problems solved by technology

[0003] The cable mainly consists of an internal cable core and a sheath covering the outside of the cable core. In order to ensure the safety performance of the cable core, the sheath is generally a plastic sheath with relatively good elasticity, thus ensuring the overall toughness of the cable. , but due to the different areas of application of the cable, for areas with high temperature or processing enterprises, the use of ordinary cable sheaths is prone to softening or melting, which can easily cause safety accidents. Flame-retardant cable sheathing materials have been introduced, but this material not only has high actual cost, but also relatively expensive materials.
