Preparation method of kaolin polymer-based regenerated EPS building external wall thermal insulation material
The invention discloses a preparation method of a kaolin polymer-based regenerated EPS building external wall thermal insulation material, the kaolin polymer-based regenerated EPS building external wall thermal insulation material comprises the following main components in mass ratio: (composite base material) 90-100: (metakaolin) 10-25: (fire retardant) 2-5: (heat stabilizer) 0.2-0.5: (mixed additive) 1-0.3: (flexibilizer) 5-7, (water glass) 8-14, (geopolymer gel) 30-50, and the balance of water, and the preparation method comprises the following seven steps. The recycled EPS base material can be modified by adding the fire retardant, the heat stabilizer, the mixed additive and the flexibilizer, so that the EPS base material has the advantages of high flame retardance, high impact resistance, environment friendliness, heat stability, good mechanical property, easiness in processing and molding and the like, and the chemical activity of the EPS base material can be reduced by gelatinizing the modified geopolymer; therefore, the EPS building external wall external thermal insulation material has good chemical stability in an erosion environment, and the geopolymer cementing material is used for replacing traditional polluting cement, so that the EPS thermal insulation material has the advantages of low cost, environment-friendly production process and the like.
本发明公开了高岭土聚物基再生EPS建筑外墙保温材料的制备方法，其主要成分与质量比为：（复合基材）90‑100：（偏高岭土）10‑25：（阻燃剂）2‑5：（热稳定剂）0.2‑0.5：（混合助剂）1‑0.3：（增韧剂）5‑7，（水玻璃）8‑14，（地聚物胶凝）30‑50，余量为：水，包括以下七个步骤。本发明通过添加阻燃剂、热稳定剂、混合助剂、增韧剂可对回收的EPS基材进行改性，可使EPS基材具有高阻燃、高抗冲、环保、热稳定、力学性能好、易加工成型等优点，通过改性地聚物胶凝可降低其化学活性，因此EPS建筑外墙外保温材料在侵蚀环境中具有良好的化学安定性，且通过地聚物胶凝材料代替了传统的具有污染性的水泥，使得EPS保温材料具有成本低、生产工艺环保等优点。
