Inorganic sizing material cold-pressed density board
The invention discloses an inorganic sizing material cold-pressed density board. According to the formula, 100 parts of light calcined magnesia, 135 parts of a magnesium sulfate aqueous solution with the baume degree of 28-30 and 0.8 part of a modifier are mixed and stirred to be uniform, then 85-110 parts of one or two or more of wood flour, bamboo powder or straw powder or jute fibers, reed powder, palm fibers, bagasse and coconut shell fibers are added, and a high-pressure process is adopted for forming, wherein the modifier in the formula is a mixture of 0.6 part of trisodium citrate, 0.2 part of polyacrylamide and 0.2 part of calcium lignosulphonate.
本发明公开了一种无机胶料冷压密度板。配方为：轻烧氧化镁100份、28‑30波美度硫酸镁水溶液135份、改性剂0.8份，混合搅拌均匀然后加入木粉、竹粉或秸秆粉或黄麻纤维、芦苇粉、棕榈纤维、甘蔗渣、椰壳纤维其中一种两种或多种85‑110份，采用高压工艺成型；配方中所述改性剂是柠檬酸三钠0.6份、聚丙烯酰胺0.2份、木质素磺酸钙0.2份的混合物。
