The invention belongs to the field of decorative materials, and relates to an ardealite foaming base material and a preparation method and application thereof.The preparation method comprises the steps that PVC resin, PVC recycled material powder, ardealite powder, a stabilizer, paraffin, stearic acid, CPE, a foaming agent, a foaming regulator and the like are mixed, stirred, heated and cooled and then conveyed to a double-screw extruder to be heated, plasticized, fused and foamed, extrusion shaping and cooling are conducted through a connected mold, and the ardealite foaming base material is obtained. Different foaming base materials are extruded through different molds, and products such as wallboards, furniture boards and decoration lines can be developed. According to the invention, hydration reaction of gypsum is not needed, phosphogypsum powder is directly used as a filling material and is mixed with other materials, heating, extrusion and cooling molding are carried out to obtain a foaming base material, the foaming base material is subjected to subsequent treatment to obtain a decorative material finished product, and the product has certain solid wood characteristics, can be sawed, drilled, nailed and glued, and is simple in process flow, low in investment cost and suitable for industrial production. The application scene of the ardealite is expanded, and the value of the ardealite product is improved.
本发明属装饰材料领域，涉及一种磷石膏发泡基材及其制备方法与应用，是将PVC树脂、PVC回收料粉料、磷石膏粉、稳定剂、石蜡、硬脂酸、CPE、发泡剂、发泡调节剂等混合搅拌加热，冷却后输送到双螺杆挤出机中加热、塑化、熔融、发泡，经连接的模具挤出定型，冷却，得到磷石膏发泡基材，不同的模具挤出不同的发泡基材，可开发墙板类、家具板类、装饰线条等产品。本发明无需经过石膏的水化反应，直接利用磷石膏粉作为填充料，与其他物料混合、加热、挤出、冷却成型得到发泡基材，发泡基材经后续处理后得到装饰材料成品，产品具有一定的实木特性，能锯、能钻、能钉、能胶合，工艺流程简单、投资成本低，拓展了磷石膏运用场景，提高了磷石膏产品的价值。
