The invention discloses a production process of a wear-resistant and corrosion-resistant WPC floor. The production process has the advantages that waste cartons, sawdust, rice husks, bagasse, wheat straw, corn straw, bagasse, pine bark, modified urea resin, a defoaming agent and a flame retardant are used as the raw materials, the proportion of the components is controlled strictly, a traditionalWPC floor formula is changed, the waste cartons, sawdust, rice husks, bagasse, wheat straw, corn straw, bagasse and pine bark are wide in source and cheap, and accordingly raw material cost is saved;a layer of wear-resisting agent formed by aluminum oxide is evenly pressed to surface layer of a large floor block, so that good corrosion resistance and long service life are achieved; water temperature can be easily controlled by a water-bath heating manner, and the required temperature environment of production is guaranteed; materials are subjected to ultraviolet sterilizing before being packaged by a packaging machine, and the mixture which is not sieved is allowed to pass a sieve in a repeated forceful grinding manner to avoid material waste; the production process is simple and suitablefor being popularized and used.
