Abstract
本发明涉及一种低烟无毒环保型PVC及其制备方法，属于聚氯乙烯加工技术领域，低烟无毒环保型PVC的制备原料包括：90‑110份PVC树脂粉、25‑35份增塑剂、8‑16份低烟阻燃剂、3‑5份稳定剂、1‑3份抗氧化剂、2‑6份润滑剂和0.5‑1份抗静电剂；所述低烟阻燃剂为芯壳结构微球，按重量份计，所述芯层由芯层分散液组成，所述芯层分散液的制备原料包括：35‑45份聚磷酸铵、10‑15份季戊四醇、8‑12份有机蒙脱土、2‑5份聚乙二醇和0.5‑1份吐温‑80；所述壳层由壳层包覆液固化得到。通过引入芯壳结构微球型低烟阻燃剂，构建膨胀阻燃协同体系，可在材料燃烧过程中快速形成致密阻隔炭层，有效隔绝氧气与热辐射，显著提升PVC基体的难燃性能。
