The embodiment of the invention discloses a preparation method of a thermal insulation material expanded by utilizing phosphogypsum, and a product. The preparation method of the thermal insulation material expanded by utilizing phosphogypsum comprises the following steps: 1, grinding and crushing phosphogypsum, and then adding water to prepare a mixture I; 2, adding anhydrous magnesium chloride into the mixture I to prepare a mixture II; 3, adding an expanding agent into the mixture II to prepare a mixture III; 4, adding light burning powder into the mixture III to prepare a mixture IV; 5, adding the expanding agent into the mixture IV to prepare a mixture V; and 6, carrying out finished product processing on the mixture V. The preparation method of the thermal insulation material expandedby utilizing the phosphogypsum gradually treats harmful components of the phosphogypsum and turns wastes into valuables, so the pollution problem of the phosphogypsum can be further solved, the wastes are turned into valuables, and the living environment is purified.
本发明实施例公开了一种利用磷石膏膨化的保温材料的制备方法及产品，所述利用磷石膏膨化的保温材料的制备方法，包括以下步骤：步骤一、将磷石膏研磨粉碎后加入水，制得混合物Ⅰ；步骤二、向混合物Ⅰ中加入无水氯化镁，制得混合物Ⅱ；步骤三、向混合物Ⅱ中加入膨化剂，制得混合物Ⅲ；步骤四、向混合物Ⅲ中加入轻烧粉，制得混合物Ⅳ；步骤五、向混合物Ⅳ中加入膨化剂，制得混合物Ⅴ；步骤六、对混合物Ⅴ进行成品加工。本发明提供的利用磷石膏膨化的保温材料的制备方法，逐步处理磷石膏的有害成分，变废为宝，可使磷石膏的污染问题得到进一步的解决，变废为宝，净化居住环境。
