Modified styrene-acrylic emulsion waterproofing agent, preparation method thereof and application thereof in phosphogypsum
The invention discloses a modified styrene-acrylic emulsion waterproofing agent, a preparation method thereof and an application of the modified styrene-acrylic emulsion waterproofing agent in phosphogypsum. The modified styrene-acrylic emulsion waterproofing agent comprises the following components in parts by weight: 30-45 parts of a polymeric monomer, 5-8 parts of a modified monomer, 5-10 parts of a composite emulsifier, 2-4 parts of a functional monomer, 0.4-0.8 part of an initiator (oxidant) and 0.6-0.8 part of sodium carbonate. According to the invention, the modified styrene-acrylic waterproofing emulsion with stable polymer is obtained by adopting a gradient dropwise adding chemical grafting method, and has the characteristics of high conversion rate, convenient synthesis process, economy, environmental protection, stable performance, small addition amount, simple preparation process and the like; when themodified styrene-acrylic emulsion waterproofing agent is applied to phosphogypsum water prevention, the softening coefficient of the phosphogypsum can reach 0.71 or above under the doping amount of 1% by mass, and the application range of the phosphogypsum is effectively widened.
本发明公开了一种改性苯丙乳液防水剂及其制备方法与在磷石膏中的应用。它包括以下重量份数计的组分：聚合单体30‑45份，改性单体5‑8份，复合乳化剂5‑10份，功能单体2‑4份，引发剂(氧化剂)0.4‑0.8份和碳酸钠0.6‑0.8份。本发明采用梯度滴加的化学接枝法得到聚合体稳定的改性苯丙防水乳液，转化率高，合成工艺方便，经济环保，性能稳定、添加量少和制备工艺简单等特点，将防水剂应用于磷石膏的防水，能够在质量分数1%的掺量下使得磷石膏的软化系数达到0.71以上，有效地增加了磷石膏的应用范围。
