Flame-resistant polyvinyl chloride cable material

Abstract

The invention discloses a flame-resistant polyvinyl chloride cable material which is characterized in that the polyvinyl chloride cable material is prepared by the following ingredients in parts by weight: 100 parts of polyvinyl chloride resin, 10-19 parts of plasticizer, 15-25 parts of calcium carbonate, 30-40 parts of filler, 8-15 parts of intumescent flame retardant, 1-6 aprts of calcium-zinc stabilizer, 6-8 parts of antimonous oxide, 5-10 parts of magnesium hydroxide, 5-10 parts of aluminium hydroxide and 0.1-1.5 parts of an antioxidant 1010, wherein the flame retardant can be inorganic flame retardants magnesium hydroxide and aluminium hydroxide, and the intumescent flame retardant pentaerythritol, and the provided flame-resistant polyvinyl chloride cable material has excellent flame-retardant property and good insulating property, and the service life of the cable can be prolonged.

Description

technical field

[0001] The invention relates to a cable material, which is a flame-retardant polyvinyl chloride cable material. Background technique

[0002] PVC cable material is a multi-component mixed material based on PVC resin and various compounding agents. Because of its superior mechanical properties, good weather resistance, excellent electrical insulation properties, easy processing, and low cost, it is widely used as insulation and sheath materials for wires and cables. The fire caused by wire and cable during use cannot be ignored. When the cable burns, it will produce toxic and harmful gases and smoke. Cables with good flame retardancy are more and more popular. In the prior art, inorganic flame retardants, In order to achieve a good flame retardant effect, compound flame retardants are often added in large amounts, which seriously affects the physical and chemical properties and service life of plastics.
