Water-resistant anti-crack gypsum block and preparation method thereof
The invention discloses a water-resistant anti-crack gypsum block which is prepared from the following raw materials in parts by weight: 600 to 750 parts of building gypsum, 150 to 200 parts of ash, 50 to 100 parts of rubber particles, 20 to 40 parts of quick lime, 10 to 20 parts of basalt fiber, 5 to 10 parts of water repellent, 1 to 3 parts of water reducing agent, 0.5 to 2 parts of defoaming agent, 50 to 100 parts of waterborne polyurethane and 500 to 650 parts of water. By adding the ash, the quick lime, the water repellent and the like, the strength and the water resistance of the gypsum are improved; pores are filled with hydrates formed among the raw materials, and the coating effect of waterborne polyurethane is utilized, so that the problem that the appearance is influenced by yellowing, whitening and the like caused by impurity migration is avoided; through the synergistic effect of the rubber particles, the basalt fibers and the waterborne polyurethane, when the gypsum is greatly deformed, brittle fracture cannot be generated, and cracking is prevented; the invention also discloses a preparation method of the water-resistant anti-crack gypsum block.
本发明公开了一种耐水型抗裂石膏砌块，由以下重量份原料组成：建筑石膏600‑750份、灰渣150‑200份、橡胶颗粒50‑100份、生石灰20‑40份、玄武岩纤维10‑20份、憎水剂5‑10份、减水剂1‑3份、消泡剂0.5‑2份、水性聚氨酯50‑100份、水500‑650份，该石膏砌块使用建筑石膏作为主要材料，通过添加灰渣、生石灰、憎水剂等，提高了石膏强度和耐水性；通过原料间形成的水化物填充毛细孔及水性聚氨酯包裹作用，避免了杂质迁移造成吐黄、发白等影响美观的问题；通过橡胶颗粒、玄武岩纤维、水性聚氨酯的协同作用，使石膏在发生较大变形时，不会产生脆性断裂，防止开裂；本发明还公开了一种耐水型抗裂石膏砌块的制备方法。
