It is further preferred that the organic acid is oxalic acid, succinic acid, citric acid, phthalic acid, tartaric acid, phthalic anhydride or fourth
One of dicarboxylic anhydride.
Preferably, the catalyst is strong concentrated acid in inorganic.
It is further preferred that the catalyst is sulfuric acid or phosphoric acid.
Preferably, the pH adjusting agent is one of AMP-95, NaOH, calcium hydroxide or KOH.PH adjusting agent is alkalinity
Substance is in neutrality solution to neutralize the acid not reacted in solution, rotten with the acid and alkali-resistance for improving concrete interface treating agent
Corrosion energy.
Preferably, the solid content of the polyvinyl acetate fat liquor is 35% or 50%.Polyvinyl acetate fat liquor does not have to
Heating or addition curing agent can direct normal temperature cure, be glued fast speed, dry shape bonding strength height, good toughness, easy to process.Add
Enter polyvinyl acetate fat liquor, the polyvinyl acetate fat liquor of the polyvinyl alcohol and specific solid content that make polycondensation acts synergistically, energy
The performances such as water resistance, viscosity, the adhesion strength of concrete interface treating agent of preparation are improved, and preparation process is simple.
A kind of preparation method of concrete interface treating agent, comprising the following steps:
After the water, defoaming agent and polyvinyl alcohol measured is added in S1 in reaction kettle, stirs and be heated to 95 DEG C, constant temperature 30
