AI Technical Summary

Technical Problem

Existing halogen-free flame-retardant computer cables, while achieving high flame-retardant performance, suffer from material embrittlement, easy cracking at low temperatures, high breakage rate, and poor compatibility between flame retardants and matrix resins, making it difficult to simultaneously achieve high flame retardancy, low toxicity and environmental friendliness, and low-temperature toughness.

Method used

By precisely designing the compounding ratio of core components and key process parameters, a synergistic optimization system is constructed. A compound of nano-aluminum hydroxide and melamine cyanurate is used, along with ethylene-vinyl acetate copolymer and maleic anhydride-grafted polyolefin, to form a gradient toughening system. Combined with a stepwise melt blending process, the uniform dispersion and functional performance of each component are ensured.

Benefits of technology

It achieves an organic unity of high flame retardancy rating, low smoke and low toxicity, halogen-free environmental protection and low temperature toughness, improves the flame retardancy efficiency, mechanical property stability and thermal aging resistance of the material, and meets the application requirements of computer cables in various scenarios.
