WOOD PLASTIC COMPOSITE HAVING EXCELLENT FLAME RETARDANT AND LOW MANUFACTURING COST, AND METHOD OF MAKING THE SAME

摘要

PURPOSE: An wood plastic composite having excellent flame retardant and low manufacturing cost, and a method of making the same are provided to maintain the adhesive force uniformly and fire retardant effect by maintaining Ph of the water glass with 0~12 Ph and limiting the solid content with 10~40%. CONSTITUTION: The wood plastic composite having excellent flame retardant and low manufacturing cost includes powdered woods and plastics. The synthetic lumber surface is coated to the water glass. The powdered woods use at least one or greater selected from a group consisting of wood shavings, sawdust, and simple fibers within 10~80 weight% range. The wood dust is used 50~60 weight%. The plastics use polypropylene, polyethylene, and polyolefin resin like polystyrene with 10~50 weight%. The water glass has 10~12 Ph. The solid content of the water glass is 10~40 weight%. The specific gravity of the water glass is 1~2.
