Abstract
本发明提供一种界面增强磷石膏轻质内墙隔板及其制备方法，按重量份计，该界面增强磷石膏轻质内墙隔板的原料包括以下组分：磷石膏：75‑95份，水泥：1‑5份，核壳结构发泡聚苯乙烯轻集料：3‑8份，缓凝剂：0.3‑0.5份，保水剂：0.2‑0.4份，减水剂：0.3‑0.5份，引气剂：0.1‑0.2份。本发明的界面增强磷石膏轻质内墙隔板以磷石膏为主要原料，并复配水泥、核壳结构发泡聚苯乙烯轻集料以及缓凝剂、保水剂、减水剂和引气剂，其中，核壳结构发泡聚苯乙烯轻集料的使用，增强了轻集料与磷石膏以及水泥的相容性，提高了轻集料与磷石膏以及水泥的的粘接强度，从而有效提高了本发明的界面增强磷石膏轻质内墙隔板的保温隔热效果和力学性能。The invention provides an interface reinforced phosphogypsum lightweight interior wall partition and a preparation method thereof. The raw materials of the interface reinforced phosphogypsum lightweight interior wall partition include the following components in parts by weight: phosphogypsum: 75-95 parts , cement: 1-5 parts, core-shell structure expanded polystyrene light aggregate: 3-8 parts, retarder: 0.3-0.5 parts, water-retaining agent: 0.2-0.4 parts, water-reducing agent: 0.3-0.5 parts , Air-entraining agent: 0.1-0.2 parts. The interface-reinforced phosphogypsum lightweight interior wall partition of the present invention uses phosphogypsum as the main raw material, and is compounded with cement, core-shell structure foamed polystyrene light aggregate, retarder, water retaining agent, water reducing agent and air-entraining agent. Among them, the use of foamed polystyrene light aggregate with core-shell structure enhances the compatibility of light aggregate with phosphogypsum and cement, improves the bonding strength of light aggregate with phosphogypsum and cement, thus The thermal insulation effect and mechanical properties of the interface-reinforced phosphogypsum lightweight interior wall partition of the present invention are effectively improved.
Description
技术领域technical field
本发明涉及建筑材料技术领域，特别涉及一种界面增强磷石膏轻质内墙隔板及其制备方法。The invention relates to the technical field of building materials, in particular to an interface-reinforced phosphogypsum lightweight interior wall partition and a preparation method thereof.
背景技术Background technique
磷石膏是工业湿法制备磷酸所产生的固体废弃物，平均每生产1吨P2O5，就会形成4.5～5.5吨的磷石膏。由于磷石膏中存在有大量杂质(主要是磷、氟和有机物)，这些杂质的存在会导致磷石膏性质的波动，使其性能不稳定，从而限制了磷石膏的利用。据不完全统计，目前我国每年排放的磷石膏在8000万吨以上，且综合利用率不足20％，总堆存量已超过5亿吨。磷石膏中残存的磷、氟和有机物等杂质会随着雨水进入地下，污染土地以及水资源，并且机械作业时扬起的磷石膏粉尘会污染空气。磷石膏的资源化综合利用已成为当前亟待解决的技术难题。利用磷石膏煅烧生成半水磷石膏，从而制备建筑材料，是目前磷石膏利用最普遍和最成熟的技术。Phosphogypsum is a solid waste produced by industrial wet preparation of phosphoric acid. On average, 4.5 to 5.5 tons of phosphogypsum will be formed for every ton of P 2 O 5 produced. Due to the existence of a large number of impurities (mainly phosphorus, fluorine and organic matter) in phosphogypsum, the existence of these impurities will lead to fluctuations in the properties of phosphogypsum, making its performance unstable, thus limiting the utilization of phosphogypsum. According to incomplete statistics, at present, more than 80 million tons of phosphogypsum are discharged in my country every year, and the comprehensive utilization rate is less than 20%, and the total stockpiles have exceeded 500 million tons. Impurities such as phosphorus, fluorine, and organic matter remaining in phosphogypsum will enter the ground with rainwater, polluting land and water resources, and the phosphogypsum dust raised during mechanical operations will pollute the air. The comprehensive utilization of phosphogypsum resources has become a technical problem to be solved urgently. Calcining phosphogypsum to generate phosphogypsum hemihydrate to prepare building materials is currently the most common and mature technology for phosphogypsum utilization.
根据住建部规划，到2020年全国城镇既有居住建筑中节能建筑所占比例要超过60％，因此安全环保高效节能的保温材料的研制迫在眉睫，而磷石膏轻质内墙隔板的研制不仅处理了磷石膏这种固体废弃物，而且也很好的体现了建筑节能的理念。然而，磷石膏轻质内墙隔板的制备过程中，轻集料与胶凝材料界面的粘结性能较差，致使其保温隔热效果不佳，且力学性能低。According to the plan of the Ministry of Housing and Urban-Rural Development, by 2020, the proportion of energy-saving buildings in existing residential buildings in cities and towns across the country will exceed 60%. Phosphogypsum, a solid waste, is eliminated, and it also embodies the concept of building energy conservation. However, in the preparation process of phosphogypsum lightweight interior wall partitions, the bonding performance of the interface between light aggregate and cementitious material is poor, resulting in poor thermal insulation effect and low mechanical properties.

磷石膏：95份，水泥：5份，核壳结构发泡聚苯乙烯轻集料：6份，缓凝剂： 0.3份，保水剂：0.4份，减水剂：0.5份，引气剂：0.1份。Phosphogypsum: 95 parts, cement: 5 parts, core-shell structure expanded polystyrene light aggregate: 6 parts, retarder: 0.3 parts, water retaining agent: 0.4 parts, water reducing agent: 0.5 parts, air-entraining agent: 0.1 part.
其中，核壳结构发泡聚苯乙烯轻集料的原料包括以下组分：Among them, the raw materials of core-shell structure expanded polystyrene light aggregate include the following components:
发泡聚苯乙烯颗粒：10份，三乙醇胺：5份，乙烯-醋酸乙烯酯：5份，聚乙烯醇：4份，水泥：34份，粉煤灰：27份，硅灰：7份，水：20份。Expanded polystyrene particles: 10 parts, triethanolamine: 5 parts, ethylene-vinyl acetate: 5 parts, polyvinyl alcohol: 4 parts, cement: 34 parts, fly ash: 27 parts, silica fume: 7 parts, Water: 20 parts.
且本实施例中发泡聚苯乙烯颗粒的粒径为4mm，堆积密度为12kg/m3。In addition, the particle size of the expanded polystyrene particles in this embodiment is 4 mm, and the bulk density is 12 kg/m 3 .
同时，本实施例中保水剂为羧甲基纤维素醚，引气剂为竹本油脂。Meanwhile, in this embodiment, the water-retaining agent is carboxymethyl cellulose ether, and the air-entraining agent is bamboo oil.
因在本实施例中，界面增强磷石膏轻质内墙隔板中磷石膏和水泥的总用量为100份，因此，本实施例在界面增强磷石膏轻质内墙隔板的制备过程中按0.5∶ 1的水灰比需称取50份水。Because in this embodiment, the total amount of phosphogypsum and cement in the interface reinforced phosphogypsum lightweight interior wall partition is 100 parts, therefore, in the preparation process of the interface reinforced phosphogypsum lightweight interior wall partition in this embodiment according to 0.5: 1 water-cement ratio needs to weigh 50 parts of water.
对本发明实施例1～实施例5的界面增强磷石膏轻质内墙隔板的性能进行测试，测试结果如表1所示。The properties of the interface-reinforced phosphogypsum lightweight interior wall partitions of Examples 1 to 5 of the present invention were tested, and the test results are shown in Table 1.
由表1可知，本发明实施例1～实施例5的界面增强磷石膏轻质内墙隔板保温性能良好，其导热系数为0.12～0.17W/(m·K)，密度小，其绝干密度为 573-895Kg/m3，机械强度高，其绝干抗压强度为3.2-6.0MPa，并且其干燥收缩值较小，其干燥收缩值为0.13-0.15mm/m。It can be seen from Table 1 that the interface-reinforced phosphogypsum lightweight interior wall partitions of Examples 1 to 5 of the present invention have good thermal insulation properties, their thermal conductivity is 0.12-0.17W/(m K), and their density is small. The density is 573-895Kg/m 3 , the mechanical strength is high, the absolute dry compressive strength is 3.2-6.0MPa, and the drying shrinkage value is small, and the drying shrinkage value is 0.13-0.15mm/m.
表1Table 1
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention within.
