【摘要】：在微膠囊化紅磷母粒和氫氧化鎂復(fù)配體系中添加少量有機(jī)蒙脫土(抗滴落劑),研究阻燃劑配比與材料阻燃性能、力學(xué)性能之間的關(guān)系。采用熔融擠出方式制備無(wú)鹵阻燃尼龍6阻隔防爆材料,并對(duì)材料力學(xué)性能、熱穩(wěn)定性、微觀形貌進(jìn)行研究。研究表明:當(dāng)氫氧化鎂和微膠囊化紅磷的比例為3∶2時(shí),協(xié)同阻燃作用最佳;阻燃劑總量為15%時(shí),材料的阻燃等級(jí)達(dá)到UL94V-0級(jí)別;當(dāng)加入1%的有機(jī)蒙脫土后,阻燃劑總含量由15%降低至14%,仍可保持阻燃級(jí)別為V-0。通過(guò)熱失重分析發(fā)現(xiàn),添加填料可以提高阻隔防爆材料的熱穩(wěn)定性;有機(jī)蒙脫土能夠插層尼龍6樹(shù)脂中,提高填料與基體間的相互作用力,具有改善阻隔防爆材料機(jī)械性能的作用。
[Abstract]:A small amount of organic montmorillonite (anti-dropping agent) was added to the microencapsulated red phosphorus masterbatch and magnesium hydroxide system to study the relationship between the ratio of flame retardants and the flame retardancy and mechanical properties of the materials. The halogen free flame retardant nylon 6 barrier and explosion proof material was prepared by melt extrusion, and the mechanical properties, thermal stability and microscopic morphology of the material were studied. The results show that when the ratio of magnesium hydroxide and microencapsulated red phosphorus is 3:2, the synergistic flame retardant effect is the best; when the total amount of flame retardant is 15, the flame retardant grade of the material reaches UL94V-0 grade, and when 1% organic montmorillonite is added, When the total content of flame retardant is reduced from 15% to 14%, the flame-retardant grade can still be maintained at V-0. By thermogravimetric analysis, it was found that the addition of fillers could improve the thermal stability of the barrier materials, and the organic montmorillonite could intercalate the nylon 6 resin to improve the interaction between filler and matrix. The utility model has the function of improving the mechanical properties of the barrier explosion proof material.
