生产多环芳烃磺酸盐聚合物混凝土减水剂的方法技术

生产多环芳烃磺酸盐聚合物混凝土减水剂的方法，涉及一种化工产品的生产工艺，特别是混凝土减水剂的生产工艺。本发明专利技术以蒽渣和浓硫酸为原料，经磺化、水解、缩合、中和制成；其中，磺化温度为７０～１２０℃。将其与浓硫酸进行低温磺化反应，不会出现蒽焦化的现象，可提高磺化生成的目的产物，提高产品收率。低温反应条件，工艺易于控制，方便操作，可节约能源，节省生产成本。更主要的是，本发明专利技术采用以往只能作为燃料的低成本原料蒽渣作为生产源料，提高了资源的利用价值，其生产的经济成本得以显著降低。

Method for producing polycyclic aromatic hydrocarbon sulfonate polymer concrete water reducing agent

The invention relates to a method for producing a polycyclic aromatic hydrocarbon sulfonate polymer concrete water reducing agent, relating to the production process of a chemical product, in particular to a production process of a concrete water reducing agent. The present invention uses anthracene residue and concentrated sulfuric acid as raw materials and is prepared by sulfonation, hydrolysis, condensation and neutralization. Wherein, the sulfonation temperature is 70~120 DEG C. The process of sulfonation with concentrated sulfuric acid will not lead to the phenomenon of anthracene coking, which can increase the yield of sulfonated products and increase the yield of products. The process is easy to control, convenient to operate, energy saving and production cost saving. More importantly, the present invention uses the low cost raw material, anthracene residue, which can only be used as fuel, as a production source material, thereby improving the utilization value of the resources and reducing the economic cost of production remarkably.
