The invention discloses a method for manufacturing a building plastic formwork by effectively utilizing ardealite waste. The method comprises the following steps: 1, preparing raw materials: taking, by weight, 50-75 parts of waste PVC plastic, 30-300 parts of ardealite and 5-10 parts of wood flour as main materials, 25-50 parts of light calcium carbonate as a modification filler, and 3-5 parts ofglass fibers and 6-8 parts of cement as auxiliary materials, and then adding 0.18-1 part of a yellow foaming agent, 0.18-0.7 parts of a white foaming agent and 1-11 parts of a foaming regulator; mixing: fully mixing the prepared raw materials at 115 DEG C, performing cold mixing at 50 DEG C after the temperature of the raw materials reaches 115 DEG C, and stopping mixing after the raw materials are cooled to 50 DEG C; molding: heating, plasticizing and foaming the raw materials, and molding the raw materials in a mold; and cutting: cutting the formed plate into the needed size to obtain a finished product. The building plastic formwork manufactured through the method is good in various properties and can be used as a formwork in the building industry, so that the problem that resources such as steel and wood are insufficient is solved, and the cost is reduced.
本发明公开了一种有效利用磷石膏废料的建筑用塑料模板制造方法，包括以下步骤：配料：以重量计份的废旧PVC塑料50‑75份、磷石膏30‑300份、木粉5‑10份作为主材，以轻质碳酸钙25‑50份作为改性填充剂，辅以玻璃纤维3‑5份、水泥6‑8份，再加入黄发泡剂0.18‑1份、白发泡剂0.18‑0.7份、发泡调节剂1‑11份；混料：将配好的原料在115℃温度环境下进行充分混合，在原料温度达到115℃后，再置于50℃温度环境下进行冷混，待原料冷却至50℃后停止混料；成型：将原料加热、塑化和发泡，并进入模具成型；切割：将成型的板材切割成需要的尺寸，得到成品。通过本发明的方法制成的塑料建筑模板，其各项性能良好，可用于建筑行业中作为模板使用，以缓解钢材和木材等资源的不足的问题，降低成本。
