Abstract

The invention belongs to the technical filed of thermoplastic polyurethane elastomer materials, and particularly relates to a halogen-free flame-retardant smoke-suppressing thermoplastic polyurethane elastomer cable material which comprises the following components in percentage by weight: 70-85% of thermoplastic polyurethane elastomer, 10-28% of halogen-free nitrogen and phosphorus flame retardant, 1-5% of smoke suppressor, 0.1-1% of antioxidant and 0.1-1% of lubricant. The halogen-free flame-retardant smoke-suppressing thermoplastic polyurethane elastomer cable material prepared by the invention produces a small amount of smoke in the combustion process, has excellent flame retardancy and excellent mechanical property, and can be used as a low-smoke halogen-free flame-retardant cable coating material. Besides, the invention also discloses a preparation method of the halogen-free flame-retardant smoke-suppressing thermoplastic polyurethane elastomer cable material.

Description

technical field

[0001] The invention belongs to the technical field of thermoplastic polyurethane elastomer materials, and in particular relates to a halogen-free flame-retardant and smoke-suppressing thermoplastic polyurethane elastomer cable material and a preparation method thereof. Background technique

[0002] Cable is an indispensable basic equipment for transmitting electric energy, transmitting information, manufacturing various motors, instruments, and meters, and realizing electromagnetic energy conversion. However, traditional PVC cables are prone to fire and combustion due to aging during use, causing fires and producing a large amount of toxic and corrosive fumes. Therefore, low-smoke, halogen-free and flame-retardant wire and cable materials must be selected to reduce the risk of fire, reduce the occurrence of fire, and protect the safety of people's lives and property.

[0003] Thermoplastic polyurethane elastomer has good comprehensive physical properties, f...
