Summary:The invention discloses a PVC (polyvinyl chloride) board and a production method thereof. The PVC board is produced from 84-86% of PVC scrap, 7-8% of calcium powder, 0.8-1.1% of a stabilizer, 3.5-4% of a foam control agent, 0.15-0.3% of a yellow foamer, 0.4-0.7% of a white foamer, 0.05-0.25% of PE (polyethylene) wax, 0.2-0.4% of OK60, 0.15-0.3% of OA6 and 1-1.7% of ACM. The production method comprises the following steps: performing low-temperature mixing, extruding, cooling and shaping. The PVC board produced by the production method is high in hardness, good in fire-proof performance and good in high temperature resistance; the production method is energy-saving, low in cost and high in efficiency.
