Problems solved by technology

[0003] In order to enhance the flame retardant properties of polyolefin cable materials, flame retardants are often added to the raw materials. At present, the common flame retardant modified materials mainly include metal hydroxides, antimony series, organic phosphorus nitrogen, etc., but the above types of flame retardants There are deficiencies in the flame retardants, that is, while ensuring the flame retardancy, it leads to a decline in the mechanical properties of the cable material.

Abstract

The invention discloses a flame-retardant and smoke-inhibiting high-strength polyolefin cable material, relates to the field of cable materials, and mainly solves the problems that the conventional polyolefin cable material cannot balance the flame retardance and mechanical properties. The cable material comprises the following raw materials in parts by weight: 96-112 parts of polyolefin, 8-14 parts of aluminum hydroxide, 3-7 parts of chitosan, 5-10 parts of a sisal extract, 1.3-2.4 parts of dicumyl peroxide, 0.3-0.9 part of a coupling agent, 1.1-1.7 parts of an antioxidant and 2.3-4.1 parts of a stabilizer. The flame-retardant and smoke-inhibiting high-strength polyolefin cable material adopts a reasonable formula and especially uses the flame retardant comprising the chitosan, the sisalextract and the aluminum hydroxide, so that the mechanical properties are greatly improved while the excellent flame retardance of the cable material is guaranteed; the flame-retardant and smoke-inhibiting high-strength polyolefin cable material has a broad market prospect and an extremely high application value.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a flame-retardant and smoke-suppressing high-strength polyolefin cable material and a preparation method thereof. Background technique [0002] Polyolefin, referred to as PE, is a thermoplastic resin obtained by polymerizing ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -70 ~ -100 ° C), good chemical stability, and can withstand most acid and alkali erosion (not resistant to oxidation properties) acid), insoluble in common solvents at room temperature, low water absorption, and excellent electrical insulation properties; but polyethylene is very sensitive to environmental stress (chemical and mechanical effects), and has poor heat aging resistance, which can be improved by adding corresponding ad...
