Abstract

The invention relates to a method for manufacturing a halogen-free flame retardant nylon sticky buckle strap, which comprises the following steps of: cleaning, dyeing, dehydration, sizing finishing, drying, retardant finishing, hot melt adhesive finishing and the like of the nylon sticky buckle strap. In the halogen-free flame retardant nylon sticky buckle strap manufactured by the method, dyes, a sizing finishing agent, a flame retardant finishing agent and a hot melt adhesive finishing agent which used in the production process do not contain halogen or heavy metal, adopt a water-based finishing agent and has zero release and no environmental pollution; compared with the prior art, the halogen-free flame retardant nylon sticky buckle strap improves the flame retardant effect, prevents the burning process from releasing toxic gas, has high visibility and meets the fireproofing safety standard of the American Boeing company and German rail vehicles; and when the halogen-free flame retardant nylon sticky buckle strap is used for sticky buckle straps of vehicles, the safety of persons and the vehicles is improved.

Description

technical field [0001] The invention relates to a method for manufacturing a nylon adhesive tape, in particular to a method for manufacturing a halogen-free flame-retardant nylon adhesive tape. Background technique [0002] Halogen elements include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Among them, astatine (At) is a radioactive element, which hardly exists in the product. Fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) are four elements in the product, especially in polymer materials. in the form of organic compounds. The halogen compounds currently used in flame retardant products are mainly PBB, PBDE, TBBP-A, PCB, hexabromododecane, tribromophenol, and short-chain chlorinated paraffins. [0003] Adding halogen (fluorine, chlorine, bromine, iodine) to flame retardant products to increase the ignition point has the advantage that the ignition point is higher than that of ordinary polymer materials, and the ignition point is abo...
