The invention provides a high-strength weather-resistant flame-retardant dividing strip which is prepared by mixing multiple raw materials and then performing extrusion molding. The raw materials comprise 100-120 parts by mass of polyvinyl chloride resin, 5-10 parts by mass of a plasticizer, 4-8 parts by mass of a stabilizer, 1-5 parts by mass of a lubricant, 1-6 parts by mass of light calcium carbonate powder, 2-4 parts by mass of a flame retardant, 0.5-2 parts by mass of an antioxidant, 5-10 parts by mass of talcum powder, 5-15 parts by mass of silicon dioxide powder and 2-4 parts by mass of titanium dioxide powder. The invention further provides a preparation method of the high-strength weather-resistant flame-retardant dividing strip. By optimizing the formula, the process steps and the process parameters, the dividing strip has higher tensile strength and weather resistance and does not change color after being used outdoors for a long time, the added flame retardant has higher flame-retardant activity and obvious smoke suppression effect, meanwhile, the interaction force between the flame retardant and a resin matrix is high, and the smoke suppression effect is good. The lasting stability of the flame-retardant effect is improved.
本申请提供了一种高强度耐候阻燃的分隔条，分隔条由多种原料混合后挤出成型制成，原料包括100‑120质量份的聚氯乙烯树脂、5‑10质量份的增塑剂、4‑8质量份的稳定剂、1‑5质量份的润滑剂、1‑6质量份的轻质碳酸钙粉末、2‑4质量份的阻燃剂、0.5‑2质量份的抗氧剂、5‑10质量份的滑石粉、5‑15质量份的二氧化硅粉末、2‑4质量份的二氧化钛粉末。还提供了一种高强度耐候阻燃的分隔条的制备方法；通过优化配方、工艺步骤以及工艺参数，使得分隔条具有更高的抗拉强度等强度和耐候性，在室外长期使用不会产生变色现象，添加的阻燃剂具备较高的阻燃活性，而且抑烟效果明显，同时该阻燃剂与树脂基体的相互作用力高，提高了阻燃效果的持久稳定性。
