Abstract

The invention discloses arginine-terminated polyethylene glycol methacrylate with a structural formula as described in the specification. The invention also discloses a preparation method for the structural formula. The arginine-terminated polyethylene glycol methacrylate provided in the invention is applied to a water reducing agent; the arginine-terminated polyethylene glycol methacrylate effectively enhances the adsorption-complexation and steric hindrance effects of the molecules of the water reducing agent by modifying the long chain of macromonomer of the water reducing agent via amino acids, increases functions of the water reducing agent and enables the water reducing agent to have a water reducing function, a corrosion inhibition function, etc.

Description

technical field [0001] The invention belongs to an admixture monomer of cement or concrete, and in particular relates to a monomer for synthesizing a concrete water reducer polymer and a preparation method thereof. Background technique [0002] Arginine is an alpha amino acid and one of the 20 common natural amino acids. Arginine is available in a wide variety of sources and can be obtained from any food that contains protein, such as meat, poultry, cheese products, fish, etc. Foods that contain a lot of arginine include chocolate, peanuts, and walnuts. [0003] Arginine is commonly used in medicine and plays an important role in various processes: cell division, wound healing, ammonia excretion, immune function, hormone secretion. Most people respond well to arginine supplements, but a small number of people experience significant side effects after several months of continued use. Anaphylaxis is the most common arginine side effect and is most common in the injectable f...
