Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1, the embodiment is a flame-retardant high-resilience PVC floor leather, which comprises a floor leather body 1, wherein the floor leather body 1 comprises a coarse fiber textile base fabric layer 2, a PVC base fabric layer 3 is arranged on the bottom surface of the coarse fiber textile base fabric layer 2, and a PVC low-foaming layer 4 and a PVC printing layer 5 are sequentially arranged on the coarse fiber textile base fabric layer 2 upwards.

More specifically, in the first embodiment, the PVC bottom material layer 3, the PVC low-foaming layer 4, and the PVC printing layer 5 are all high flame retardant PVC resin layers, wherein the high flame retardant PVC resin layers are material members formed by blending and plasticizing flame retardant PVC resin powder, fillers, and auxiliaries; the tradition generally adopts to add the fire retardant in ordinary PVC resin and gives flame retardant efficiency, but is hindered the restriction that the fire retardant mixes the dispersion, and the fire retardant grade of product generally can reach V1 level, and the utility model discloses a high fire retardant PVC resin layer is earlier through the PVC material, the fire retardant is processed into fire-retardant PVC resin powder through homogeneous mixing earlier, again with plasticizer, modifier, stabilizer, foamer, another fire retardant, filler and colouring material etc. carry out mixing processing, the fire retardant homogeneity is better in the product of making, fire retardant grade is higher, further promotes the flame retardant efficiency of PVC plastic flooring.
