Abstract
The invention discloses a composite floor base material which comprises a bottom plate, a surface plate, a core plate located between the bottom plate and the surface plate, and four side plates. A fiber web is laid between the bottom plate and the core plate. A thin plate is laid between the core plate and the surface plate. A plurality of first hollow slim tubes extending upwards in the vertical direction are arranged on the fiber web, and the two ends of the first slim tubes are open. A plurality of first through holes and a plurality of second through holes are formed in the thin plate. Second slim tubes extending downwards in the vertical direction are arranged on the lower surface of the thin plate. The upper ends of the second slim tubes stretch into the thin plate and communicate with the first through holes and the second through holes. Third through holes and fourth through holes are formed in the side plates. First round grooves and second round grooves are formed in one side face of each side plate. The first slim tubes and the second slim tubes communicate with the third through holes and the fourth through holes correspondingly, and thus air ventilation paths are formed. The composite floor base material is simple in production technique, good in ventilation property and air permeability and worthy of wide popularization on the market and has the advantage of being environmentally friendly.
