Abstract

The invention relates to a room-temperature synthetic type polycarboxylic high performance water-reducing agent and a preparation method thereof. The room-temperature synthetic type polycarboxylic high performance water-reducing agent is prepared form the following components including isopentenol polyoxyethylene ether, acrylic acid, methacrylic acid, sodium allylsulfonate, sodium methallyl sulfonate, hydrogen peroxide, ammonium persulfate, L-ascorbic acid, sodium dithionite, mercaptoacetic acid, mercaptopropionic acid, sodium hydroxide and water. The room-temperature synthetic type polycarboxylic high performance water-reducing agent is suitable for synthesis and production at room temperature, is high in product water-reducing rate and good in slump loss resistant property, has wide market prospect as the production process has a series of advantages of saving energy, lowering consumption, improving the efficiency, being green and environment-friendly and the like and is widely suitable for high-quality concrete of commercial concrete in various grades, high-speed railways, expressways, large bridges, precast elements, airports, port construction and the like.

Description

Technical field [0001] The present invention is the field of concrete exterior preparation, which involves a high -performance water reducing agent and preparation method of normal temperature synthetic polycarboxylic acid system. Background technique [0002] The concrete exterior agent is a material added before or during the concrete mixing or during the mixing process to improve the performance of new mixing and hardening concrete. It is characterized by a small amount and a large effect.The application of various concrete exterior agents has improved the many properties of new mixing and hardening concrete, promoted the development of new concrete technology, expanded the application of industrial by -products in glue materials, and help saves resources and environmental protection. It has gradually become high -quality high -qualityThe component of concrete is indispensable. [0003] Around 2000, my country's concrete engineering community gradually realized the high -perfo...
