    15%~20% glass fibre and 80%~85% PVC powder；
    10%~15% composite fibre and 85%~90% PVC powder, wherein the composite fibre is by following weight percent At being grouped as：10%~25% carbon fiber and 75%~90% glass fibre；
    10%~20% composite fibre and 80%~90% PVC powder, wherein the composite fibre is by following weight percent At being grouped as：15%~30% basalt fibre and 70%~85% glass fibre；
    5%~10% composite fibre and 90%~95% PVC powder, wherein the composite fibre is by following weight percent At being grouped as：35%~40% carbon fiber and 60%~65% basalt fibre；
    8%~12% composite fibre and 88%~92% PVC powder, wherein the composite fibre is by following weight percent At being grouped as：5%~10% carbon fiber, 5%~10% basalt fibre and 80%~90% glass fibre, and three kinds The sum of content percentage of fiber is equal to 100%；
    Step 6: step 4, which is obtained low temperature PVC powder batch mixing, feeds the first feeding hopper, seven fibre types that step 5 is obtained Reinforced polyvinyl chloride material is respectively fed into the second feeding hopper, and the first feeding hopper and the second feeding hopper are defeated to screw extruder simultaneously Material is sent, by screw rod melting, shearing and is squeezed out, adjusts surface layer Screw Extrusion amount using resolving device, material is after Screw Extrusion Obtain the sticky shape raw material of seven types；
    Step 7: mold molding and cooling treatment
    The sticky shape raw material of seven types that step 6 is obtained is sent into die molding machine, and cooling temperature is set as 5 in forming process DEG C~15 DEG C, obtain seven fibre types reinforced polyvinyl chloride composite floor substrates.
    Step 8: cut-out packaging
    The fiber reinforcement polyvinyl chloride composite floor substrate longitudinal direction automatic cutting for seven types that step 7 is obtained, respectively according to Technological requirement transversely cutting is at sheet material, after the assay was approved, carries out follow-up Compound Machining, obtains fiber reinforcement polyvinyl chloride compoundly Plate.
