Preparation method of low-sand high-stone concrete suspending agent
The invention discloses a preparation method of a low-sand high-stone concrete suspending agent and relates to the field of suspending agent production.The suspending agent is prepared from HPEG methyl allyl polyoxyethylene ether, water, ammonium persulfate, long-chain alkane mineral oil and sodium methylene dinaphthalene sulfonate.The preparation method comprises the following steps that firstly, the HPEG methyl allyl polyoxyethylene ether and the water are mixed, stirred and stirred, and a mixture is obtained; heating to a specified temperature; step 2, dropwise adding ammonium persulfate (APS); 3, simultaneously stirring long-chain alkane mineral oil, and continuously stirring for a certain time, so that the mixture is uniformly dispersed; and 4, sodium methylene dinaphthalene sulfonate (a dispersant NNO). By arranging the HPEG methyl allyl polyoxyethylene ether, the water, the ammonium persulfate, the long-chain alkane mineral oil and the sodium methylene dinaphthalene sulfonate, the suspending agent has excellent suspension stability and efficient dispersity, can be widely applied to the fields of cement concrete and the like, and aims at solving the problems of insufficient stability, poor dispersity and the like existing in an existing suspending agent.
本发明公开了一种低砂高石混凝土悬浮剂的制备方法，涉及悬浮剂生产领域，所述悬浮剂包括HPEG甲基烯丙基聚氧乙烯醚、水、过硫酸铵、长链烷烃矿物油、亚甲基二萘磺酸钠,所述包括以下步骤：步骤一：将HPEG甲基烯丙基聚氧乙烯醚和水，加热至规定温度；步骤二：过硫酸铵(APS)滴加；步骤三：长链烷烃矿物油，同时进行搅拌，继续搅拌一定时间，使混合物均匀分散；步骤四：亚甲基二萘磺酸钠(分散剂NNO)。本发明通过设置HPEG甲基烯丙基聚氧乙烯醚、水、过硫酸铵、长链烷烃矿物油、亚甲基二萘磺酸钠，该悬浮剂具有优异的悬浮稳定性和高效分散性，可广泛应用于水泥混凝土等领域，针对现有悬浮剂存在的问题，如稳定性不足、分散性不佳等。
