Abstract

The invention provides a formulation and a production method of a radiation cross-linked heat-shrinkable halogen-free flame-retardant marking sleeve product, which comprises: ethylene vinyl acetate copolymer 20-40; ethylene acrylate copolymer 0-10 ; Maleic anhydride graft polymer 1-15; Silicone masterbatch 1-15; Ultrafine surface treatment activated aluminum hydroxide 10-20; Ultrafine surface treatment activated magnesium hydroxide 10-20; Zinc borate 1-10; Surface treatment superfine red phosphorus 0-10; organic nitrogen phosphorus flame retardant 0-10; titanium dioxide 0-5; lubricant 0.2-1; antioxidant 0.5-1; sensitizing crosslinking agent 0.5-2; light stabilizer 0.5-2; color masterbatch 1-5. The manufactured label sleeve has good properties such as flame retardancy, machinery, insulation, wear resistance, corrosion resistance, and light aging resistance. Using thermal transfer printing, the writing is clear, the service life is more than 20 years, and the mark has good wipe resistance and solvent resistance. Easy to use, use nylon cable ties to bind large-size cables where they need to be marked. Radiation crosslinking greatly improves the mechanical properties and flame retardancy of the product.

Description

technical field [0001] The invention relates to the technical field of marking sleeves, in particular to a formulation and a manufacturing method of a radiation-crosslinked heat-shrinkable halogen-free flame-retardant marking sleeve product. Background technique [0002] In order to meet the needs of special occasions and harsh conditions, the heat shrinkable marking sleeve has good mechanical and insulation properties, adopts thermal transfer printing, clear writing, and a service life of more than 20 years. Permanent marking, heat aging resistance, corrosion resistance, and light stability Well, it's easy to use and has good flame retardant properties. Halogen-containing polymers or flame-retardant mixtures combined with halogen-containing flame retardants have excellent flame-retardant properties and have been widely used as flame-retardant materials. When a fire occurs, such halogen-containing flame-retardant materials will produce a large amount of smoke and toxic corr...
