Abstract

The invention relates to a processing method of an environment-friendly spartina anglica substitute wood plate. The substitute wood plate can consume a large amount of cut spartina anglica which is processed into a spartina anglica slurry by cutting, extrusion tearing, rough grinding and fine grinding. The slurry is mixed with thermosetting adhesive and additives which do not contain harmful components of formaldehyde and benzene, and microwave enhanced cross-linking treatment enable the substitute wood plate to have the characteristics of high density, high strength and high toughness, have excellent machinability such as sawing, planing, punching, and nailing, and have very wide application fields. After a flame retardant magnesium chloride glue is solidified, kieserite is formed, whichnot only improves the fireproof performance of the substitute wood plate, but also prevents the substitute wood plate from being eroded by any microorganism. The processing method provided by the invention is simple and enables products to have a wide application range.

Description

technical field [0001] The invention belongs to building boards, in particular to a processing method of an environment-friendly rice straw instead of wood board. Background technique [0002] Out of the need to prevent waves and embankments and protect tidal flats, Fujian Province introduced Spartina from abroad in the 1980s. Due to its well-developed root system and strong penetrating power, Spartina grew wantonly and has covered two-thirds of Fujian Province. tidal flats. The rampant growth of Spartina not only encroached on the living space of the original vegetation, resulting in the disappearance of large areas of mangroves, but also caused a large number of organisms such as shellfish, crabs, algae, and fish to suffocate and die due to hypoxia. Aquaculture has also suffered a devastating blow. In short, the crazy growth of Spartina has greatly damaged the ecological environment, and it has been included in the list of foreign harmful species in my country. [0003] ...
