在 PVC 铺地用块材的配料中加入较多量的 CaCO_3填充剂,可改变产品的物理机械性能,降低成本,本文对其进行了理论分析和试验研究。CaCO_3填充剂的密度、加入量及产品配方对产品的质量有直接影响。为此,对原有 PVC铺地块材的配方及 CaCO_3填充剂的选取实施了改进,同时对块材进行了合理的表面活化及热处理,改变了 CaCO_3与 PVC 分子的亲合力,并使 PVC 分子链由弯曲变直,从而提高了产品质量,降低了成本,获得了较高的经济效益。 Adding a large amount of CaCO_3 filler into the ingredients of the block for PVC flooring can change the physical and mechanical properties of the product and reduce the cost. In this paper, theoretical analysis and experimental research are carried out. CaCO_3 filler density, dosage and product formulations have a direct impact on the quality of the product. To this end, the existing PVC floor block formula and CaCO_3 fillers were implemented to improve the block at the same time a reasonable surface activation and heat treatment, changing the affinity of CaCO_3 and PVC molecules, and PVC molecules Straightening the chain by bending, thereby improving product quality, reduce costs, access to higher economic benefits.
