[0003] The cable mainly consists of the inner cable core and the sheath covering the cable core. Since there will be a lot of gaps between the cable core and the sheath of a normal cable, if such gaps are not filled in time, it will be very large. To a certain extent, it will affect the overall strength of the cable. At this stage, people deal with this kind of problem by adding fillers insid

Example Embodiment
[0015] Example 1
[0016] Weigh the following raw materials: sand 50kg, cordierite powder 20kg, mullite powder 20kg, asbestos powder 10kg, calcium carbonate 10kg, perlite 10kg, cornstarch 20kg, polyvinyl chloride 15kg, chlorinated rubber 13kg, phenolic resin 15kg, 15 kg of chlorinated paraffin, 10 kg of tributyl phosphate, 5 kg of zinc borate, 6 kg of aluminum borate, and 8 kg of silicone oil.
[0017] The preparation method is as follows:
[0018] a. Use a grinder to mix the sand, cordierite powder, mullite powder, asbestos powder, calcium carbonate, perlite, and cornstarch in the raw materials, then put them in for grinding and crushing, and then filter to obtain the particle diameter After it is 1-2mm, take it out for use;
[0019] b. Put all the polyvinyl chloride, chlorinated rubber, phenolic resin and chlorinated paraffin in the raw material into a hot melting furnace and heat it to dissolve at high temperature, then stir it evenly, then extrude and granulate through an extrude...

Abstract
The invention discloses a fireproof filling material used for a special cable, and relates to the technical field of cable processing. The fireproof filling material is prepared from the following raw materials in parts by weight: 50-60 parts of sandy soil, 20-30 parts of cordierite powder, 20-30 parts of mullite powder, 10-20 parts of asbestos powder, 10-20 parts of calcium carbonate, 10-20 parts of perlite, 20-30 parts of titanium dioxide, 15-25 parts of polyvinyl chloride, 13-15 parts of chlorinated rubber, 15-25 parts of phenolic resin, 15-25 parts of chlorinated paraffin, 10-20 parts of tributyl phosphate, 5-7 parts of zinc borate, 6-8 parts of aluminium borate, and 8-10 parts of a lubricant. The fireproof filling material has the benefits that the technological process is simple, the proportion of the raw materials is reasonable, the preparation method is simple, a high-quality filling agent is provided for the cable, the raw materials are easy to obtain, high temperature resistance is achieved, a certain flame retardancy is achieved, safety accidents caused by overhigh temperature of a cable core are avoided, the use effect is obvious, the reasonable use of the special cable is guaranteed.
Description
technical field [0001] The invention relates to the technical field of cable processing, in particular to a fireproof filler for special 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 manufactur...
