Description
The technical field is as follows:
the invention relates to a shaving board and a preparation method thereof, in particular to a regenerated shaving board prepared by using solid waste sanding powder generated in artificial board processing, crop straws and a biological resin adhesive as a bonding agent, namely the invention particularly relates to a biomass resin adhesive regenerated board and a preparation method thereof.
Secondly, background art:
china is a world large country for producing and consuming artificial boards. According to statistics, the yield of the artificial board in China in 2017 reaches 2.95 billion cubic meters, and the demand of the artificial board reaches 2.91 billion cubic meters. The yield of Chinese artificial board products accounts for 50-60% of the total yield of global artificial boards. With the expansion of the industrial scale of the artificial board, the problem of ecological environmental pollution caused by the artificial board is increasingly prominent, and the artificial board becomes a restrictive factor in the industrial development process. Although the structural reform of the supply side of the Chinese artificial board industry is initially successful and obsoletes the backward capacity of 4000 more than ten thousand cubic meters, the production process of the artificial board determines that the artificial board is easy to generate various environmental pollutants such as dust, volatile organic matters and the like. Effective prevention and control and utilization of the pollutants of the three wastes in the production process of the artificial board are the key for ensuring the healthy development of the artificial board industry.
Sanding powder is solid waste generated in the production of fiber boards, shaving boards and plywood and also is an important source of dust pollution in the production process. The sanding powder produced in each year is at least more than one million cubic meters based on 3 billion cubic meters of the artificial board produced in each year in China. At present, the method for treating the sanding powder mainly comprises the following two methods: firstly, the sanding powder is used as biomass fuel for a boiler, and secondly, the sanding powder is used as filler for producing fiber boards or shaving boards. However, the disadvantages of this are also apparent. Firstly, with the increase of the national air pollution treatment strength, the traditional coal-fired boiler is gradually replaced by concentrated steam supply, and simultaneously, the safety and the economic operation of the boiler are also influenced due to the small density, the flammability and the explosiveness and the large glue content of the sanding powder. Secondly, urea-formaldehyde resin is mostly adopted in the traditional production of shaving boards and fiber boards, and the sanding powder has larger specific surface area, so that the glue application amount is correspondingly increased, and the formaldehyde emission amount of the board exceeds the standard; and the sanding powder is doped, so that the sand content of the fiberboard product is high, and the bonding strength in the product is influenced.
In a word, the sanding powder treatment methods adopted at present have certain disadvantages. Therefore, an economic and environment-friendly sanding powder treatment method is developed and plays an important role in quality improvement and upgrading of the artificial board industry.
