摘要：
The present invention provides a polyvinyl chloride polymer (PVC) composite material including 40-60 parts by weight of PVC, 40-60 parts by weight of light calcium carbonate, 0.8-1.2 parts by weight of composite foaming agent including an inorganic foaming agent and an organic foaming agent, 3-5 parts by weight of foam regulator, 2-4 parts by weight of toughener, 0.8-1.2 parts by weight of lubricant, and 1.5-2.5 parts by weight of stabilizer. The ratio of the inorganic foaming agent to the organic foaming agent by weight in the composite foaming agent is ½-1. Meanwhile, the present invention provides a foam board made of the PVC composite material, an associated production method, an apparatus, and flooring. The resulting PVC products have a high-strength structure and a good foaming property, thus having a satisfied mute effect.
