一种透明PVC粒料及其生产方法
摘要：
本发明涉及一种透明PVC粒料及其生产方法，该粒料由聚氯乙烯基料100重量份、内润滑剂1~2重量份、热稳定剂1.0~1.5重量份、增塑剂DOP1~40重量份、抗冲改性剂3~10重量份、加工助剂ACR1~2重量份、外润滑剂0.2~0.8重量份及颜料组成。本发明通过将聚氯乙烯基料、内润滑剂、热稳定剂、增塑剂、抗冲改性剂、加工助剂、外润滑剂、颜料进行优化配比，研究出具有一定透明性、良好加工性、耐候性、稳定性及力学性能的透明PVC粒料配方，生产出能满足挤出、延压等成型工艺要求的透明PVC粒料配方，达到了提高透明度的目的。本发明可广泛应用于PVC粒料的技术改进中，特别适用于透明PVC粒料及其生产方法中。
摘要（英）：

The invention relates to a transparent polyvinyl chloride (PVC) granule and a production method thereof. The granule consists of the following components in part by weight: 100 parts of PVC base material, 1 to 2 parts of an internal lubricant, 0.1 to 1.5 parts of a heat stabilizer, 1 to 40 parts of plasticizer dioctyl phthalate (DOP), 3 to 10 parts of an impact modifier, 1 to 2 parts of a processing aid ACR, 0.2 to 0.8 part of an external lubricant and the balance of pigment. By optimally proportioning the PVC base material, the internal lubricant, the heat stabilizer, the plasticizer, the impact modifier, the processing aid, the external lubricant and the pigment, a transparent PVC granule formula which has certain transparency, high processability, weather resistance, stability and mechanical performance and can meet requirements of molding processes such as extrusion and extension pressing is researched and produced, and the aim of improving the transparency is fulfilled. The invention can be widely applied to technical improvement of PVC granules, in particular to the transparent PVC granule and the production method thereof.
