[0003] The cable mainly consists of the inner cable core and the sheath covering the cable core. In order to ensure the toughness of the cable, the cable is usually filled with a lot of fillers during production. At this stage, the inner filler of the cable core Generally, it is directly filled with plaster of paris powder. Although certain effects can be obtained, due to the fixed substance, the texture is relatively hard and the elasticity is low. Therefore, problems such as cracking and breaking are prone to occur during use, causing safety hazards.

Abstract
The invention discloses a high-elasticity sealing matrix for a cable and relates to the technical field of cable processing. The high-elasticity sealing matrix is prepared from, by weight, 30-40 parts of epoxy resin, 20-30 parts of acrylic resin, 30-40 parts of polyurethane resin, 60-80 parts of white oil, 15-25 parts of limestone, 25-35 parts of chlorinated paraffin, 10-20 parts of lauric acid dibutyl tin, 80-100 parts of montmorillonitepowder, 100-200 parts of asphalt, 15-25 parts of talcum powder, 60-80 parts of bentonite, 40-60 parts of kaolin, 10-20 parts of sodium polyacrylate, 3-5 parts of a modifier and 6-8 parts of a reinforcing agent. The high-elasticity sealing matrix and the preparation method have the advantages that the technical process is concise, raw materials are cheap and easy to get; an anti-adhesion powder composition prepared by the method can directly act on the outer wall of a cable inner jacket, and the high-elasticity sealing matrix is hard in texture, elastic, good in rebound performance, less prone to aging and cracking, easy-to-get in raw material, low in cost and simple to process.
Description
technical field [0001] The invention relates to the technical field of cable processing, in particular to a highly elastic sealing matrix for cables 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 cable manuf...
