Road water-stable base biomass retarder, preparation method and application
The invention discloses a road water-stable base biomass retarder as well as a preparation method and application thereof. The biomass retarder comprises the following materials: 70%-90% of a sodium galactobionate solution, 5%-15% of lignosulfonate and 5%-15% of sodium benzoate. The road water-stable base biomass retarder is prepared by the following steps: performing a series of biological treatments on whey to obtain a galactose solution, oxidizing the galactose solution to obtain a galactosic acid solution, adding a NaOH solution in the fermentation process to neutralize to obtain a sodium galactosylate solution, and adding the sodium galactosylate solution to obtain the road water-stable base biomass retarder. And mixing the raw materials, and fully stirring to obtain the biomass retarder. Compared with an existing retarder, the biomass retarder is derived from whey which is a byproduct in the dairy product processing industry, is low-carbon, environment-friendly, low in price, safe and harmless, simple in preparation process and easy to popularize and use, and can remarkably prolong the cement setting time and ensure the construction quality of a water-stable base of a road.
本发明公开了一种道路水稳基层生物质缓凝剂、制备方法及应用。所述生物质缓凝剂包括以下材料：70％～90％半乳糖酸钠溶液、5％～15％木质素磺酸盐、5％～15％苯甲酸钠。该道路水稳基层生物质缓凝剂通过以下步骤制得：乳清经过一系列的生物处理，得到半乳糖溶液，半乳糖溶液经过氧化得到半乳糖酸溶液，在发酵过程中加入NaOH溶液进行中和得到半乳糖酸钠溶液，然后将原材料混合、充分搅拌得到生物质缓凝剂。相比于现有的缓凝剂，该生物质缓凝剂来源于奶制品加工行业副产品乳清，低碳环保，价格低廉，安全无害，制备流程简单，易于推广使用，并且能够显著延长水泥凝结时间，确保道路水稳基层的施工质量。
