| titleOfInvention | A kind of method adopting microwave assisting method to prepare the efficient superplasticizer of poly carboxylic acid graft copolymer class |
| abstract | The present invention relates to a kind of method adopting microwave assisting method to prepare the efficient superplasticizer of poly carboxylic acid graft copolymer class.This superplasticizer selects A, B, D, C or F, E or G seven kinds of polymer monomer copolymerization form, and its preparation method is that (1) sets certain temperature, microwave irradiation power; (2) under microwave radiation, add polymer monomer, namely in polymer chain, introduce the long side chain of polyethers, polyester and heteroatoms; (3) Ph value is adjusted in neutralization.The present invention prepares the water soluble polycarboxylic acid Concrete superplastizer of gained, possesses high water reducing rate, molecular weight dispersion index is little, over-all properties is more superior, excellent to cement consistency, and it is short to have synthesis environmental protection, synthesis cycle, technique is simple, and cost is low, reasonable price, is suitable for applying. |
