Abstract

The invention discloses a high performance antifreeze special for concrete, and the high performance antifreeze comprises the following raw materials by weight: 0.3-0.6 part of sodium dodecylbenzenesulfonate, 0.1-0. 4 parts of polyacrylamide, 7 to 12 parts of PET hydrolyzate, 0.4 to 0.8 part of sodium lignosulfonate, 0.7 to 1.2 parts of sodium alkyl sulfonate, 0. 3-0.8 part of diisopropanolamine,0.4-1 part of sodium methylene dinaphthalene sulfonate, 0.4-0.8 part of a polycarboxylic acid sputum retaining agent, 0.4-0.9 part of alkyl glycoside and 0.3-0.9 part of sodium hexametaphosphate. Thehigh performance antifreeze special for the concrete has the advantages such as good effect, no cracking, corrosion resistance, wide application range, good waterproof and impermeability.

Description

technical field [0001] The invention relates to the related technical field of building concrete, in particular to a special high-performance antifreeze agent for concrete. Background technique [0002] So far, the pumping antifreeze used in construction projects at home and abroad are all formulated with water-reducing components, compounded with early-strength components, antifreeze components and air-entraining components. The water-reducing components include naphthalene sulfonate formaldehyde condensate (naphthalene-based high-efficiency water reducer), sulfonated melamine formaldehyde condensate, lignosulfonate; early components include sulfate, carbonate, nitrate, etc. Most of them are sodium salts; the antifreeze components include nitrite, nitrate, chloride salt, urea and ammonia water. Chlorine salts will corrode the steel bars and affect the service life of the building; urea, ammonia water, etc. release pungent odors, affecting the quality of life. Nitrite has c...
