Novel halogen-free flame retardant modification thermoplastic elastomer data line sheath material and manufacturing method thereof

Abstract

The invention discloses a novel halogen-free flame retardant modification thermoplastic elastomer data line sheath material. The novel halogen-free flame retardant modification thermoplastic elastomer data line sheath material is characterized by comprising, by weight, 100-104 parts of SEBS, 65-68 parts of paroline, 29-31 parts of polypropylene, 21-23 parts of maleic anhydride grafted polypropylene, 3-4 parts of antioxygen B215, 81-83 parts of magnesium hydroxide, 10.5-12 parts of expanded graphite, 1.6-1.7 parts of a silane coupling agent A-171, 8-9 parts of absolute ethyl alcohol, 2-3 parts of stearic acid, 9-11 parts of calcium carbonate, 2-3 parts of silicone master batch, 1-1.5 parts of zinc oxide, 5-7 parts of maleic acid and 1.5-2 parts of polyvinyl alcohol. According to the novel halogen-free flame retardant modification thermoplastic elastomer data line sheath material, a blend of the paroline modified SEBS and the polypropylene is used as a matrix, and the composition proportion is scientific and reasonable, so that the obtained product is high in tensile strength, good in thermostability, pliable, tough, good in processing fluidity, remarkable in flame retardant efficiency, free of halogen, environmentally friendly, capable of being widely applied to power lines, data lines and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a novel halogen-free flame-retardant modified thermoplastic elastomer data line sheathing material and a preparation method thereof. Background technique [0002] At present, more than 90% of the electronic wire sheath materials, insulating materials and electronic plug materials widely used in the domestic electronic and electrical industry are made of PVC. However, since July 1, 2006, the European Union has issued a decree to prohibit the entry of electronic and electrical products containing certain harmful substances such as halogen flame retardants and heavy metals into the European market. This has had a serious impact on the export of electronic and electrical products in my country. While the European Union issued its ban, some foreign companies have begun to vigorously promote their products to my country's electrical industry, trying to seize the Chinese marke...

Problems solved by technology

[0004] At present, most of the halogen-free flame-retardant TPE products on the market use aluminum hydroxide, phosphate composite flame retardant and P-N intumescent flame retardant of ammonium polyphosphate system. Flexibility, mechanical properties are greatly reduced, and hardness is increased; the flame-retardant TPE prepared by the phosphate composite flame retardant has poor flame retardancy, and the phosphate is easy to migrate to the surface of the material for a long time; and ammonium polyphosphate (APP) Although the P-N intumescent flame retardant of the system has high flame retardant efficiency, the water resistance of ammonium polyphosphate is poor, and the electrical properties of the flame retardant TPE products prepared by it are poor.
