Method for producing PVC (polyvinyl chloride) building profile by using ardealite as filler
The invention discloses a method for producing a PVC building profile by using phosphogypsum as a filler, and belongs to the technical field of building profile preparation, the PVC building profile comprises the following raw materials by weight: 90-110 parts of beta-type hemihydrate gypsum, 15-25 parts of a foaming agent, 1-3 parts of a water repellent, 1-5 parts of a water reducer, 2-4 parts of a reinforcing agent, 1-3 parts of a retarder, and 15-24 parts of water. The ardealite is used as a filler to produce the PVC building profile, the characteristics that the ardealite is subjected to hydration reaction when encountering water, generated dihydrate gypsum colloid particles are continuously increased, the consistency of slurry is continuously increased, and the adhesion among the particles is gradually enhanced are utilized, and the foaming agent, the water repellent, the water reducing agent, the reinforcing agent and the retarder are matched for use; the prepared PVC profile has the characteristics of compression resistance, tensile resistance, wear resistance and good fireproof performance. The preparation method is simple, the production process is easy to operate, and the method is suitable for large-scale production and application.
本发明公开了一种应用磷石膏作为填料生产PVC建筑型材的方法，属于建筑型材制备技术领域，包括以下重量份的原料：β型半水石膏90～110份，发泡剂15～25份，憎水剂1～3份，减水剂1～5份，增强剂2～4份，缓凝剂1～3份，水15‑24份。本发明应用磷石膏为填料生产PVC建筑型材，利用磷石膏遇水发生水化反应，随着生成的二水石膏胶体微粒不断增多，浆体的稠度不断增加，微粒间的黏结逐步增强的特性，配合发泡剂，憎水剂，减水剂，增强剂，缓凝剂的使用，使得制成的PVC型材具有抗压、抗拉伸、耐磨损、防火性能好的特点。本发明制备方法简单，生产过程易操作，适于规模化生产应用。
