Description
技术领域 technical field
本发明属于蒙皂石无机凝胶颗粒及其制备领域，特别涉及一种水中易崩解分散的蒙皂石无机凝胶颗粒及其制备方法。The invention belongs to the field of smectite inorganic gel particles and preparation thereof, in particular to smectite inorganic gel particles easily disintegrated and dispersed in water and a preparation method thereof.
背景技术 Background technique
蒙皂石无机凝胶是汉克托石或钠基蒙脱石类粘土矿物的精细化工产品，一般产品通常为颗粒很细的白色粉末，无味、无毒、无刺激性，不溶于水、乙醇和有机溶剂中。但浸水溶胀，在水溶液中较低固含量下就能分散形成高透明度、高粘度的性能均一的凝胶体。一般应用于化妆品、洗涤用品、涂料、油漆、日用化工品、锂电池、印染助剂、润滑剂、粘合剂、净化剂等领域用作增稠剂、触变剂、悬浮稳定剂、抗流挂剂，能提高相应产品质量、降低生产成本、增加经济效益。Smectite inorganic gel is a fine chemical product of hectorite or sodium montmorillonite clay minerals. The general product is usually a white powder with very fine particles, odorless, non-toxic, non-irritating, and insoluble in water and ethanol. and organic solvents. However, it swells when soaked in water, and can be dispersed to form a gel with high transparency and high viscosity and uniform performance at a low solid content in the aqueous solution. Generally used in cosmetics, detergents, coatings, paints, daily chemicals, lithium batteries, printing and dyeing auxiliaries, lubricants, adhesives, purifiers and other fields as thickeners, thixotropic agents, suspension stabilizers, anti-corrosion Hanging agent can improve the quality of corresponding products, reduce production costs and increase economic benefits.
目前，市售的蒙皂石无机凝胶产品通常为经超细粉碎的粒径小于75微米的粉体，产品在生产、运输、储存和使用过程中极易发生扬尘现象。如操作人员不加防护，吸入人体肺部后，再很难排出。如在肺泡组织内累积到一定数量就会对人体呼吸系统造成不可逆转的损害，即矽肺病，此类疾病是目前最严重、最普遍的职业病之一。主要原因是蒙皂石无机凝胶粉末中不可避免的含有颗粒极细的石英和方英石矿物。这两种物质已被医学界认定为导致人类矽肺病和肺癌的主要元凶，特别是方英石类矿物，由于结晶不完全，表面活性高，危害更大。因此，粉末状蒙皂石无机凝胶无论在生产、包装、运输和使用过程中只要发生扬尘，就可能会对人体造成潜在危害。At present, the commercially available smectite inorganic gel products are usually superfinely pulverized powders with a particle size of less than 75 microns, and the products are prone to dusting during production, transportation, storage and use. If the operator is not protected, it will be difficult to discharge after inhalation into the lungs of the human body. If it accumulates to a certain amount in the alveolar tissue, it will cause irreversible damage to the human respiratory system, that is, silicosis, which is one of the most serious and common occupational diseases at present. The main reason is that the smectite inorganic gel powder inevitably contains very fine quartz and cristobalite minerals. These two substances have been identified by the medical community as the main culprits of human silicosis and lung cancer, especially cristobalite minerals, which are more harmful due to incomplete crystallization and high surface activity. Therefore, as long as dust is generated during the production, packaging, transportation and use of powdered smectite inorganic gel, it may cause potential harm to the human body.
而如果将蒙皂石无机凝胶产品加工成的较粗的颗粒(粒径大于500微米)，尽管可减少扬尘，但在使用过程中则需要较高转速的搅拌机并且花费较长时间才能打散，这会严重影响产品品质和使用效果，使用户难以接受。And if the smectite inorganic gel product is processed into coarser particles (particle size greater than 500 microns), although dust can be reduced, a mixer with a higher speed is required during use and it takes a long time to break up , which will seriously affect product quality and use effect, making it difficult for users to accept.
