Phosphogypsum-magnesium oxysulfate cementing material composite fireproof partition plate and preparation method thereof
The invention provides an phosphogypsum-magnesium oxysulfate cementing material composite fireproof partition plate and a preparation method thereof. The fireproof partition plate comprises the following raw materials by weight: 0-40% of phosphogypsum, 10-40% of light calcined magnesia, 10-40% of magnesium sulfate heptahydrate, 0-10% of sawdust, 0.3-0.6% of a modifier, 0.05-0.15% of polypropylene fiber and 30-45% of water. From the perspective of environment and economy, problems in comprehensive utilization of phosphogypsum waste are solved, a phosphogypsum-magnesium oxysulfate composite gel system is adopted to prepare the fireproof partition plate, so mass production can be performed on the basis of meeting requirements on product performance and strength, the utilization rate of phosphogypsum is greatly increased, the use amount of a magnesium oxysulfate system and product cost are reduced and after the phosphogypsum is added, and the method has relatively obvious environmental benefits and economic benefits. The fireproof partition plate prepared prepared according to the above formula and under certain process conditions is non-toxic and harmless, does not release formaldehyde, and has excellent fireproof, waterproof and moisture-proof properties and the like on the premise of maintaining the strength of the partition plate.
本发明提供一种磷石膏—硫氧镁胶凝材料复合防火隔板及制备方法，所述的防火隔板由以下重量百分比的原料组成，其中含有：磷石膏0‑40％、轻烧氧化镁10‑40％、七水硫酸镁10‑40％、木糠0‑10％、改性剂0.3‑0.6％、聚丙烯纤维0.05‑0.15％、水30‑45％。本发明从环境角度和经济角度出发，解决磷石膏废物综合利用问题，采用磷石膏—硫氧镁复合胶凝体系制备防火隔板，在满足产品性能和强度的基础上可以进行大批量生产，磷石膏的利用率大大提高，并且加入磷石膏后还降低了硫氧镁体系的使用量，减少了产品成本，因此具有较为明显的环境效益和经济效益。本发明的配方和工艺条件下制得的防火隔板无毒、无害，且无甲醛释放，同时在兼顾隔板强度前提下具有防火、防水、防潮等优良性能。
