Abstract

The invention relates to the technical field of PET monofilaments and in particular to a PET flame-retarding monofilament. The PET flame-retarding monofilament comprises a PET core beam and a flame-retarding layer covering the outside of the PET core beam. The flame-retarding layer comprises the following raw materials in parts by weight: 80-100 parts of ultraviolet curable resin, 20-30 parts of polyvinyl chloride resin, 20-35 parts of polyurethane resin, 3-6 parts of wood meal, 4-6 parts of a porous phyllosilicate flame retardant, 5-9 parts of a flexibilizer, 5-7 parts of a compatilizer, 8-12parts of an antioxidant, and 80-100 parts of an organic solvent. The PET flame-retarding monofilament has excellent flame resistance and drop resistance, and is good in smoke suppression effect.

Description

technical field [0001] The invention relates to the technical field of PET monofilaments, in particular to PET flame-retardant monofilaments. Background technique [0002] PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface, good creep resistance, fatigue resistance, friction resistance, low wear and high hardness, and has the greatest toughness among thermoplastics; good electrical insulation performance , is less affected by temperature, has good weather resistance and chemical resistance stability, but the flame retardancy of PET monofilament itself is not enough, so it cannot be suitable for applications related to high flame retardancy. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a PET flame-retardant monofilament, which has excellent flame-retardant performance and anti-dripping performance, and has a good smok...
