Environment-friendly efficient water reducing agent with excellent corrosion resistance

Abstract

The invention discloses an environment-friendly efficient water reducing agent with excellent corrosion resistance. The water reducing agent is prepared by, by weight, 240-250 parts of TPEG, 25.2-26.0 parts of acrylic acid, 1.6-1.65 parts of ammonium persulfate, 0.53-0.55 part of thioglycolic acid, 13-14 parts of lignin, an appropriate amount of sodium hydroxide solution with the concentration being 10wt%, an appropriate amount of deionized water, 26-28 parts of graphene oxide, 2-3 parts of urea, 1.3-1.5 parts of sodium pyrithione, 0.8-1 part of potassium sorbate, 9-11 parts of polypropylene fiber, 2-3 parts of OP-10, 4.5-5 parts of molybdenum disulfide, 6-7 parts of quartz powder and 2-3 parts of EVA latex. The environment-friendly efficient water reducing agent has the advantages that the water reducing agent is scientific and reasonable in component proportion; the polypropylene fiber is added to be matched with the molybdenum disulfide, so that the dispersity of the water reducing agent in concrete can be increased, and the crack resistance of the concrete can be increased; components such as the sodium pyrithione are added to allow the water reducing agent to have excellent corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of concrete admixtures, in particular to an environmentally friendly high-efficiency water reducer with excellent anticorrosion performance. Background technique [0002] Polycarboxylate high-performance water-reducing agent is an important component material for preparing high-performance concrete. It is widely used in high-speed railways, bridges, Nuclear power, hydropower and other key projects. However, the performance of the mother liquor of polycarboxylate high-performance water reducer is relatively single, which cannot meet the needs of concrete in different engineering fields and different performance requirements, which greatly restricts the wide application and development of polycarboxylate high-performance water reducer. Experts and scholars at home and abroad have conducted systematic research on polycarboxylic acid-based high-performance water reducers through chemical and physical modificati...
