Abstract

The invention discloses a production method for a green and environment-friendly rice husk plate. The production method comprises the following preparation steps: preparing pure rice husk; carrying out surface treatment in a manner of combining a physical method with a chemical method; uniformly mixing glue; paving; pre-pressing; carrying out hot-pressing forming; carrying out fixed-length edge cutting; curing; drying; carrying out trimming and surface treatment; and obtaining the product, wherein in the step of surface treatment, a small amount of nanometer material capable of pitting a waxy surface under the temperature condition of greater than 120 DEG C is added at first, then chemical raw materials occupying 0.01%-0.5% of wheat straw, having structures similar to the waxy structure of the surface of the rice husk, containing silicon-oxygen chemical bonds and having similar or approximate structures are added, and finally an adhesive capable of forming hydrogen bonds or chemical bonds with a polyhydroxyl structure is added, and the dosage of the adhesive is 0.1%-5%. The plate prepared by the method is free from harmful gas emission, smooth, uniform and beautiful in texture, light-weight and environment-friendly, free from toxic substance release, high in strength, flame-retardant, sound-isolation and moistureproof, and is a wood plate substitute which is low in price and excellent in performance.
