Document Type and Number:
WIPO Patent Application WO/2023/000317
Kind Code:
A1
Abstract:
A polyvinyl chloride (PVC) plastic alloy tile, comprising a PVC plastic alloy composite material and an anti-aging film layer located on the surface of the PVC plastic alloy composite material. The PVC plastic alloy composite material comprises the following components in parts by weight: 60-80 parts of a modified rigid PVC resin; 20-40 parts of ABS; 5-12 parts of a compatibilizer; 5-12 parts of a flame retardant; 10-25 parts of an inorganic filler; and 2-8 parts of other additives. The modified rigid PVC resin and the ABS are compounded in an appropriate ratio, such that the mechanical properties and flame retardant properties of the material can be improved. Moreover, an anti-aging film layer is attached to the surface of the PVC plastic alloy tile by co-extrusion, such that the occurrence of aging and discoloration of the plastic alloy tile material exposed to strong sunlight, etc., can be effectively prevented.
