Abstract

The invention relates to a polymer compound and particularly relates to a ternary grafted copolymer and a preparing method and application thereof. The copolymer is prepared from itaconic acid, 2-acrylamido-2-methyl-1-propanesulfonic acid and allyl polyoxyethylene ether through a grafting copolymerization reaction, and has a structure shown in the specification. The copolymer has excellent dispersibility, enables good slurry mobility as a coal water slurry additive, is suitable for a wide range of coal varieties and can be compounded with various dispersants. The copolymer has excellent scaleinhibition performance and can effectively prevent deposition of inorganic calcium scales. The invention also provides the preparing method of the copolymer. The whole production process is free of ''three waste" emission, and a product is non-phosphorus and free of toxic substance, thus meeting the national environment protection requirements of China. The invention further provides application of the copolymer, with the dosage being saved and the efficiency being high.

Description

technical field [0001] The invention relates to a polymer compound, in particular to a ternary graft copolymer and its preparation method and application. Background technique [0002] Energy is the cornerstone of the development and progress of human society. With the rapid development of the economy and the continuous acceleration of the industrialization process, my country's demand for energy will continue to grow. Fossil energy is currently the most important primary energy, and coal has an irreplaceable position in fossil energy. However, the massive development and utilization of fossil energy has led to the greenhouse effect and global warming. At the same time, the large-scale use of coal has brought serious environmental pollution. In view of energy shortage and environmental protection requirements, and the structure of China's fossil energy resources presents the characteristics of rich coal, poor oil, and little gas, the clean and efficient utilization of coa...
