Manufacturing method of flame-retardant type wall decorative plate
The invention discloses a manufacturing method of a flame-retardant type wall decorative plate. The method comprises the following steps of 1) pyrolyzing sawdust in a reactor to obtain charcoal powder, naturally cooling the charcoal powder to 350-400 DEG C, proportionally mixing and stirring the charcoal powder and wood powder, and introducing hot flue gas to heat to obtain a base material; 2) adding phosphoric acid, boric acid, ammonium phosphate and guanylurea phosphate into water, and stirring to obtain flame-retardant liquid; 3) proportionally mixing and stirring the base material and theflame-retardant liquid, circularly pressurizing and decompressing for 3-4 times, and standing for 12-14 hours; 4) subjecting on the modified wood powder, the phosphoric acid, the boric acid and the ammonium phosphate to esterification reaction to obtain a wood-based flame-retardant base material; and 5) adding starch and carbon fibers into the wood-based flame-retardant base material, stirring, homogenizing for 1-3h, putting the materials into a mold, demolding, drying, edging, polishing, and carrying out surface varnish treatment to obtain the flame-retardant wall decorative plate. The decorative plate has the advantages of being good in flame retardant property, attractive in appearance and long in service life.
本发明公开了一种阻燃型墙面装饰板的制造方法，包括以下步骤：1)木屑入反应器热解，完成热解后得到木炭粉，木炭粉自然冷却至350‑400℃时，木炭粉与木粉按比例混合搅拌，并通入热烟气进行加热，得到基料；2)磷酸、硼酸、磷酸铵、脒基脲磷酸盐加入到水中搅拌，得到阻燃液；3)基料与阻燃液按比例混合搅拌，循环加压、减压3‑4次，静置12‑14h；4)改性木粉和磷酸、硼酸、磷酸铵发生酯化反应，得到木基阻燃基料；5)向木基阻燃基料中添加淀粉、碳纤维搅拌，均化1‑3h后入模具，脱模后经干燥、磨边、抛光、表面清漆处理后得到阻燃型墙面装饰板。本发明具有阻燃性能好、外形美观、使用寿命长的优点。
