Embodiment Construction

[0032] A method for producing a green and environment-friendly rice straw board, characterized in that it is prepared according to the following steps:

[0033] Moisture content 10% ~ 15% rice straw scraps to 1 mm ~ 30mm long small pieces → combined physical and chemical methods surface treatment → uniform glue mixing → paving → pre-pressing → hot pressing → cutting to length → health preservation → drying → trimming and surface treatment → product;

[0034]In the surface treatment step, chemical raw materials containing silicon-oxygen bond structure similar or similar to the waxy structure of the straw surface are added, specifically: silicone resin, basic silicon oxide, silanol ester, polysilanol ester, Sodium salt of silanol ester, sodium salt of polysiliconate or a kind of borax to increase the affinity between its molecules, and then add a small amount of nano-particles that can pit the waxy surface under high temperature conditions (above 90°C) material, the nano-materi...

Abstract

The invention discloses a green and environment-friendly straw stalk plate production method. The method comprises the preparation methods of straw stalk crushing, surface treatment of a physical and chemical phase combination method, uniform glue mixing, paving, pre-pressing, hot press forming, sizing side cutting, maintenance, drying, trimming and surface treatment and product forming. In the step of surface treatment, a silicon-oxygen chemical bond structure containing similar chemical raw material similar to the straw surface wax structure is added, then a small quantity of nano-material capable of achieving pitting on the wax surface under the condition with the temperature being 90 DEG C or above is added, then an adhesive capable of forming a hydrogen bond or a chemical bond with a polyhydroxy structure is added, finally, uniform mixing is carried out through a physical method, and surface treatment is carried out. A plate prepared through the method is light, environment-friendly and free of harmful substance release, achieves high strength, fire resisting, sound insulation and dampproofness, is level and unified and attractive in texture and is a wood plate substitute article low in price and excellent in performance.

Description

technical field [0001] The invention relates to a method for preparing a rice straw fiber board, in particular to a production method for a green and environment-friendly rice straw board. It belongs to the technical field of building components and decoration. Background technique [0002] my country is a big grain producer and also a big producer of straw. It can produce more than 100 million tons of straw every year, accounting for about 20% to 30% of the total straw in the world. Among them, the straw of rice, wheat, soybean, corn, potato and other food crops is 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 the amount of agricultural waste such as straw The research and development of comprehensive utilization of new technologies, the scientific and efficient use of straw resources, and the prohib...
