Concrete synergist and preparation method thereof
The invention discloses concrete synergist and a preparation method thereof. The concrete synergist comprises, by weight, 10-30 parts of alcamines substances, 8-18 parts of organic alcohol, 5-15 parts of methacrylic acid copolymers, 4-12 parts of alkaline inorganic salt, 0.1-2 parts of hydroxyl silicones, 0.5-4 parts of tripolyphosphate and 35-60 parts of water, and the methacrylic acid copolymers refer to one or two copolymers among methacrylic acid-hydroxyethyl acrylate copolymer co-MAA-HEA of which the molecular weight is 50000-6000 and the block proportion MAA: HEA is (3-4): 1, methacrylic acid-hydroxy-propyl acrylate copolymer co-MAA-HPA of which the molecular weight is 40000-50000 and the block proportion MAA: HPA is (4-5): 1 and methacrylic acid-ethyl acrylate co-MAA-EA of which the molecular weight is 30000-40000 and the block proportion MAA: EA is (4-6): 1. The concrete synergist is free from strong odor and toxicity, high in efficiency and environmental friendly.
