Powdery adhesive for ground phosphate rock cold-pressed pellets
The invention discloses a powdery adhesive for powdered rock phosphate cold-pressed pellets and a preparation method of the powdery adhesive, the powdery adhesive comprises the following raw materials: a thickening agent, a curing agent and a temperature resistant agent, the thickening agent comprises waterborne polyurethane powder and acetylated phosphoglycan latex, and the curing agent comprises a curing agent and a temperature resistant agent. The curing agent comprises graft modified polyvinyl acetate, silica sol, silicon phosphate, an inorganic gelling cross-linking material (MO) and a cross-linking agent (YN), and the temperature-resistant agent comprises a natural plant conversion extract, titanium dioxide and boric sludge. The powdery adhesive for the powdered rock phosphate cold-pressed pellets is formed by compounding organic and inorganic materials, and contains a high-adhesion component, a normal-temperature rapid curing component and a medium-high temperature resistant component, so that a small amount of adhesive can provide high adhesion at normal temperature to bond powdered rock phosphate powder, the pelletizing rate of the pellets is increased, the strength is increased, and the service life of the pellets is prolonged. The drying field or time is reduced, the pulverization rate at medium and high temperatures is reduced, and the production energy consumption of enterprises is reduced.
本发明公开了一种磷矿粉冷压球团用粉状粘合剂，现提出该粉状粘合剂的制备方法，包括原料配方组成：增稠剂、固化剂和耐温剂，所述增稠剂包括水性聚氨酯粉和乙酰化磷酸酯聚糖乳胶，所述固化剂包括接枝改性聚醋酸乙烯酯、硅溶胶、磷酸硅、无机胶凝交联材料(MO)和交联剂(YN)，所述耐温剂包括天然植物转化提取物、二氧化钛和硼泥。由于提供的磷矿粉冷压球团用粉状粘合剂是有机、无机材料复合而成的，其中含有高粘结力成分、常温下快速固化成分和耐中高温成分，少量粘合剂可以在常温下提供高黏结力将磷矿粉粉末粘接起来，使球团成球率提高，强度增加，晾晒场地或时间减少，中高温时粉化率降低，并降低企业生产能耗。
