一种改性PVC及其制备方法
摘要：
该发明涉及一种改性PVC，包括以下原料组分：环氧氯丙烷改性PVC、改性硫化钙、氧化铝、改性硫酸钙和1，3，5‑三甲基‑2，4，6‑（3，5‑二叔丁基‑4‑羟基苯甲基）苯，环氧氯丙烷改性PVC粒料由PVC粒料、环氧氯丙烷、氢氧化钠、乙醇、水和二乙胺基代甲基三乙氧基硅烷反应制得，改性硫化钙由磷酸单乙基酯、1,5‑萘二胺、乙醇和硫化钙反应制得，硫化钙由硫氢化钙、水、乙醇、十二烷基苯磺酸钠、二乙胺基代甲基三乙氧基硅烷和硫脲反应制得，改性硫酸钙由硫酸钙、乙醇、聚乙烯醇和聚酰胺树脂反应制得。该发明具有优异的紫外线屏蔽性、阻燃性、耐高温性、力学性能、导热性能、低体积收缩率等优势。
摘要（英）：

The invention relates to a modified PVC which comprises the following raw material components: epoxy chloropropane modified PVC, modified calcium sulfide, aluminum oxide, modified calcium sulfate and 1,3.5-trimethyl-2,4,6-(3,5-ditert-butyl-4-hydroxybenzyl)benzene, wherein epoxy chloropropane modified PVC granules are prepared by reaction among PVC granules, epoxy chloropropane, sodium hydroxide, ethyl alcohol, water and diethyl amino methyl triethoxy silane; the modified calcium sulfide is prepared by reaction among ethyl dihydrogen phosphate, 1,5-naphthalenediamine, ethyl alcohol and calcium sulfide; the calcium sulfide is prepared by reaction among sulfur calcium hydroxide, water, ethyl alcohol, sodium dodecyl benzene sulfonate, diethyl amino methyl triethoxy silane and thiourea; and the modified calcium sulfate is prepared by reaction among calcium sulfate, ethyl alcohol, polyvinyl alcohol and polyamide resins. The modified PVC disclosed by the invention has such excellent advantages as ultraviolet shielding property, flame-retardant property, high temperature resistance, mechanical property, heat-conducting property and low volume shrinkage rate.
