The invention provides a base material layer of a micro-foaming SPC floor and the micro-foaming SPC floor. Based on the total weight of the base material, the base material provided by the invention contains 65.0 to 75.0 wt% of calcium carbonate, 18.0 to 25.0 wt% of polyvinyl chloride resin, 2.2 to 3.0 wt% of a foaming regulator, 2.5 to 3.3 wt% of a stabilizer, 0.10 to 0.20 wt% of a plasticizer, 0.10 to 0.15 wt% of an external lubricant, 0.1 to 0.40 wt% of an ADC foaming agent and 0.5 to 1.0 wt% of an NC foaming agent. According to the SPC floor, the static bending intensity, the bending elastic modulus and the peel strength can be improved while the density of the SPC floor is greatly reduced, and heating warping is reduced.
本发明提供微发泡SPC地板的基材层及微发泡SPC地板。以基材总重计，本发明的基材含有65.0～75.0wt％的碳酸钙，18.0～25.0wt％的聚氯乙烯树脂，2.2～3.0wt％的发泡调节剂，2.5～3.3wt％的稳定剂，0.10～0.20wt％的增塑剂，0.10～0.15wt％的外润滑剂，0.1～0.40wt％的ADC发泡剂，和0.5～1.0wt％的NC发泡剂。本发明能在极大地降低SPC地板密度的同时提高静曲强度、弯曲弹性模量和剥离强度，并减少加热翘曲。
