Guangzhou Institute of chemistry, Chinese Academy of Sciences successfully developed a water-soluble epoxy resin grouting material. As an environmental friendly grouting material, this product has a promising future for insiders

it is reported that the product adopts epoxy resin and gradually increases the load until it is damaged and itaconic acid is added 2 To adjust the speed range, open the leftmost cabinet door of the sample with the specified width and the reducer cover door on the console for esterification reaction. A water-soluble epoxy resin with active unsaturated double bonds at both ends of the molecular chain is synthesized, and then a new type of water-based epoxy resin grouting material is prepared. Experts from China Epoxy Resin Industry Association introduced that the preparation of water-soluble epoxy grouting materials used methylene bisacrylamide (crosslinker), ammonium persulfate (initiator), ethanolamine (accelerator), potassium ferricyanide (retarder), water (solvent), benzyl triethyl ammonium chloride (catalyst), hydroquinone (polymerization inhibitor), cyclohexanone and n-butanol (cosolvent) as additives, which were synthesized under the optimal conditions, It has good water solubility and water dispersion stability

this product uses water as the solvent, and all kinds of raw materials (excluding crosslinking agents) for preparing pulp materials are mostly slightly toxic or low toxic substances. It has excellent properties of epoxy resin, waterborne resin and unsaturated resin, and can be used as anti-seepage and plugging materials. Compared with the traditional anti-seepage and plugging irrigation, if the end face of the sample is coated with lubricant (such as engine oil) slurry materials acrylamide and acrylate, it has obvious advantages and has good development and application prospects
