Abstract

The invention involves a high -performance water reduction agent and preparation method of normal temperature synthetic polycarboxylic acid system.Actinyl polyoxide ether, acrylic acid, methyl acrylic, sodium acrylics, sodium methacryonic acid sodium sulfonate, ammonium sulfate, L‑ anti -hemorrhonic acid, sodium dienticate, cymbic acid, hydrogen, hydrogen, hydrogen, hydrogen, hydrogen, hydrogen, hydrogen hydrogen, hydrogen hydrogenComposition of sodium oxide and water.The present invention is suitable for synthetic production at room temperature. The product has a high water reduction rate and good collapse. Because the production process has a series of advantages such as energy conservation and consumption reduction, green environmental protection, and improving efficiency, the market prospects are broad.The products of the present invention are widely applicable to high -quality concrete such as various levels of commercial concrete, high -speed railway, highway, large bridge, prefabricated components, airports, and port construction.

Description

technical field [0001] The invention belongs to the field of preparation of concrete admixtures, in particular to a room temperature synthetic polycarboxylate high-performance water reducer and a preparation method. Background technique [0002] Concrete admixture is a material added before or during concrete mixing to improve the performance of freshly mixed and hardened concrete. It is characterized by a small amount and a large effect. The application of various concrete admixtures improves many properties of freshly mixed and hardened concrete, promotes the development of new technologies for concrete, expands the application of industrial by-products in cementitious materials, helps save resources and protect the environment, and has gradually become a high-quality An essential component of concrete. [0003] Around 2000, my country's concrete engineering circles gradually became aware of polycarboxylate high-performance water reducing agents, because of its low dosage...
