Embodiment Construction

[0028] A kind of production method of green environmental protection rice husk plate is characterized in that it is prepared according to the following steps:

[0029] Pure rice husk→surface treatment by combining physical and chemical methods→uniform glue mixing→pavement→pre-pressing→hot pressing forming→cutting to length→health preservation→drying→edge trimming and surface treatment→products;

[0030]In the surface treatment step, the wax on the surface of the rice husk is treated by a combination of physical and chemical methods. Starting from the waxy structure on the surface of the rice husk, first add a small amount of wax that can pit the waxy surface at a temperature above 120°C. The addition amount is 0.01% to 0.5% of the mass percentage of wheat straw raw materials, and the nanomaterials are nano-magnesium oxide microcapsules, nano-calcium oxide microcapsules, nano-sodium oxide microcapsules, nano-potassium oxide microcapsules or nano-alkaline A type of silicon oxide...

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.

Description

technical field [0001] The invention relates to a method for preparing rice straw fiber boards, in particular to a production method for green and environment-friendly rice husk boards. It belongs to the technical field of building components and decoration. Background technique [0002] my country is a big country of grain production and also a big country of straw production. It can produce more than 100 million tons of straw every year, accounting for about 20%-30% of the total straw in the world. Among them, rice, wheat, soybean, corn, potato and other food crop straw About 580 million tons, accounting for 89% of the total straw; peanut, rapeseed, sesame, sunflower and other oil crop straw accounted for 8% of the total, cotton and sugarcane straw accounted for 3% of the total, increasing agricultural waste such as straw The research and development of new technologies for the comprehensive utilization of straw, the scientific and efficient use of straw resources, the proh...
