Abstract

The invention discloses an anti-mud water reducer and a preparation method thereof, the anti-mud water reducer is prepared from the following raw material components in parts by mass: 30-50 parts of TPEG, 1-5 parts of acrylic acid, 5-10 parts of sodium methallyl sulfonate, 2-8 parts of a monoalkenyl cyclodextrin monomer, 1-5 parts of polyethylene glycol-4000, 1-5 parts of cellulose ether, a properamount of a sodium hydroxide water solution and a proper amount of deionized water. The water reducer is good in anti-mud adaptability, low in doping amount, high in water reducing effect and stablein quality.

Description

technical field [0001] The invention relates to a mud-resistant water reducer and a preparation method thereof, belonging to the technical field of water reducers. Background technique [0002] Polycarboxylate high-performance water-reducer is the basic material for preparing high-performance concrete. It has excellent properties such as high water-reducing rate, high slump retention, high reinforcement and high durability, and is more and more widely used in concrete engineering. However, due to the wide variety of raw materials used in the production of concrete, the regional differences are large, and with the serious deterioration of sand and gravel aggregates, the content of clay minerals is getting higher and higher. A large number of engineering examples and studies have shown that clay minerals will lead to a decrease in the strength and durability of concrete, and significantly reduce the dispersion performance of water reducers, especially polycarboxylate water red...
