Embodiment 1
[0025] A method for preparing a high flame-retardant artificial board, said preparation method comprising the following steps: firstly, selecting sawdust and shavings, removing impurities such as sand, dust and iron filings by screening and magnetic absorption, crushing, and then steaming at 110°C 15min, then dry until the moisture content is lower than 5.0%, the obtained dried raw material and high flame-retardant rubber powder are mixed evenly in the mixer, and the core layer is obtained by loading the billet, hot pressing once, and cooling; secondly, prepare the upper surface layer and The lower surface layer, the upper and lower surface layers are all made of veneer with a thickness of 1.0mm, and the upper and lower surface layers and the core layer are evenly coated with an appropriate amount of molten high flame-retardant rubber powder, and then combined with the core layer, after two times Hot pressing, cooling, trimming and grinding process to produce highly flame retar...
Embodiment 2
[0035] A method for preparing high flame-retardant artificial boards. The preparation method includes the following steps: first, select sawdust and shavings, remove impurities such as sediment, dust and iron filings by screening and magnetic absorption, crush them, and then steam them at 120 ° C. 15min, then dry until the moisture content is lower than 5.0%, the obtained dried raw material and high flame-retardant rubber powder are mixed evenly in the mixer, and the core layer is obtained by loading the billet, hot pressing once, and cooling; secondly, prepare the upper surface layer and The lower surface layer, the upper and lower surface layers are all made of veneer with a thickness of 1.2mm, and the upper and lower surface layers and the core layer are evenly coated with an appropriate amount of molten high flame-retardant rubber powder, and then combined with the core layer, after two times Hot pressing, cooling, trimming and grinding process to produce high flame retarda...
Embodiment 3
[0045] A method for preparing high flame-retardant artificial boards. The preparation method includes the following steps: first, select sawdust and shavings, remove impurities such as sand, dust and iron filings by screening and magnetic absorption, crush them, and then steam them at 115 ° C. 20min, then dry until the moisture content is lower than 5.0%, the obtained dried raw material and high flame-retardant rubber powder are mixed evenly in the mixer, and the core layer is obtained by loading the billet, hot pressing once, and cooling; secondly, prepare the upper surface layer and The lower surface layer, the upper and lower surface layers are all made of veneer with a thickness of 1.1mm, and the upper and lower surface layers and the core layer are evenly coated with an appropriate amount of melted high flame-retardant rubber powder, and then combined with the core layer, after two times Hot pressing, cooling, trimming and grinding process to produce highly flame retardant...
