Waterproof and wear-resistant composite floor and production method

Sound absorbing waterproof flooring planks comprising at least three layers, wherein the at least three layers comprise a first upper layer, a second core layer, and a third waterproof layer, wherein each layer having an upper planar surface and a lower planar surface,

• said first upper layer comprising PVC,
• lower planar surface of said first upper layer having a plurality of micro holes formed by a corona process;
• said second core layer comprising a soft cushion material,
• the upper and lower planar surfaces of said second core layer having a plurality of micro holes formed by a corona process,
• and glue between the lower planar surface of said first upper layer and the upper planar surface of said second core layer;
• the upper planar surface of said third waterproof layer having a plurality of micro holes formed by a corona process, and glue between the lower planar surface of said second core layer and the upper planar surface of said third waterproof layer,
• and the micro holes having a diameter and depth of from 0.01-0.1 mm.
