Water-soluble polymer and application thereof

Abstract

The invention provides a water-soluble polymer. The water-soluble polymer is obtained by polymerization of a hydrophobic monomer A, a macromonomer B1 and an alkenyl-containing quaternary ammonium saltmonomer C; or the hydrophobic monomer A and at least one of the macromonomer B, an acrylic monomer D, a sulfonic monomer E and a phosphonic monomer F; or the hydrophobic monomer A, the macromonomer B1 and an electroneutral monomer G. The invention also provides application of the water dispersible polymer in concrete or cement. When used as a pumping agent, the water dispersible polymer providedby the invention has viscosity reduction properties, at the same time can endow concrete with good fluidity, and segregation and bleeding resistance, and ensures considerable transmission stability.

Description

technical field

[0001] The invention belongs to the field of macromolecules, and in particular relates to a water-soluble polymer and its application. Background technique

[0002] With the rapid development of the economy and the continuous improvement of construction technology, as well as to solve the contradiction between the growth of urban population and the serious shortage of urban construction land and the rapid expansion of the scale of traffic construction, the development of high-rise concrete structures has become inevitable, which will affect the concrete. Construction performance, mechanical properties and durability requirements are getting higher and higher. Pumping concrete technology has become one of the main development trends in concrete technology.

[0003] With the technological improvement of modern construction equipment, the performance requirements of pumped concrete are also continuously increasing. In order to meet higher workability, durabili...
