Preparation method of nano calcium carbonate for photovoltaic sealant
The invention discloses a preparation method of nano calcium carbonate for a photovoltaic sealant, which comprises the following steps: calcining limestone to remove impurities so as to obtain lime, slaking, refining and sieving the lime, adding a dispersing agent, grinding and dispersing so as to obtain raw slurry, adding a crystal form control agent into the raw slurry so as to obtain Ca (OH) 2 raw slurry, pumping the Ca (OH) 2 raw slurry into a stirring carbonization tower, and stirring for carbonization so as to obtain the nano calcium carbonate for the photovoltaic sealant. Adding kiln gas to obtain nano calcium carbonate slurry, adding a compound surface treating agent into the nano calcium carbonate slurry to obtain modified calcium carbonate slurry, and filtering, drying, crushing, grading and packaging the modified calcium carbonate slurry to obtain the special nano calcium carbonate product for the photovoltaic adhesive. The method has the beneficial technical effects that when the nano calcium carbonate and the organic silicon sealant are processed and filled, the processing is easy, the viscosity is lower, the dispersity is good, the raw materials used in the method are cheap and easy to obtain, the cost is low, the process is simple and feasible, the method is suitable for industrial production, and the economic benefit and the social benefit are better.
本发明公开了一种用于光伏密封胶的纳米碳酸钙的制备方法，通过将石灰石经过煅烧去杂质获得石灰，再将石灰消化、精制和过筛后，加入分散剂并进行研磨分散得到生浆，在生浆中加入晶型控制剂得到Ca(OH)2生浆，将Ca(OH)2生浆泵入搅拌碳化塔，加入窑气后得到纳米碳酸钙浆，纳米碳酸钙浆加入复配表面处理剂得到改性碳酸钙浆液，改性碳酸钙浆经过滤、干燥、粉碎、分级和包装后得到光伏胶专用纳米碳酸钙产品。其有益技术效果为：纳米碳酸钙与有机硅密封胶进行加工填充时，易于加工，粘度较低、具有良好的分散性，本方法所用原料廉价易得，成本低廉，工艺简单可行，适用于工业化生产，具有较好的经济效益和社会效益。
