Preparation method of halogen-free flame-retardant macromolecular waterproof coiled material main body material
The invention discloses a preparation method of a halogen-free flame-retardant macromolecular waterproof coiled material main body material, and relates to the technical field of waterproof coiled material production.The method comprises the following steps that an intumescent flame retardant with modified starch as a carbon source and superfine metal hydroxide are compounded to obtain a composite flame retardant; the compound raw materials are accurately fed and proportioned through the feeding system; mixing a composite elastomer, an ultraviolet light initiator, a cross-linking agent, an antioxidant, polyolefin and the compounded composite flame retardant serving as raw materials, and putting into a double-screw extruder; carrying out pre-granulation treatment after extruding and plasticizing, re-plasticizing through a single-screw extruder, and then extruding into a mold to obtain a waterproof base layer sheet; and cooling and molding. Airflow enters from the air inlet through the elastic tarpaulin and is blown out from the air supply net, and at the moment, when the rotating rollers rotate, powdery raw materials at the bottom can generate a fluidization effect, so that the materials are prevented from caking, and a guarantee is provided for accurate feeding and proportioning of the materials.
本发明公开了一种无卤阻燃高分子防水卷材主体材料的制备方法，涉及防水卷材生产技术领域,该方法包括以下步骤：用改性淀粉为碳源的膨胀型阻燃剂与超细化金属氢氧化物复配获得复合阻燃剂，复配原料的通过上料系统进行精确上料配比；将复合弹性体、紫外光引发剂、交联剂、抗氧剂与聚烯烃以及复配后的复合阻燃剂作为原料进行混合后投入双螺杆挤出机；经过挤出塑化后进行预造粒处理，通过单螺杆挤出机进行再次塑化，然后挤出到模具中得到防水基层片材；冷却成型。本发明通过弹性篷布使得气流从进风口进入，并从送风网处吹出，此时转动辊在转动作用时，可以让底部的粉状原料产生流化效应，从而避免物料结块，为物料的精确上料配比提供了保障。
