The invention relates to the field of concrete interface agents, and particularly discloses a freeze-thaw resistant breathable concrete interface agent. The interface agent is prepared from the following raw materials in parts by weight: 50 to 100 parts of ordinary Portland cement, 10 to 20 parts of sulphoaluminate cement, 10 to 20 parts of gypsum, 10 to 20 parts of silica fume, 10 to 20 parts offly ash, 50 to 100 parts of PTB emulsion, 10 to 15 parts of waterborne acrylate laminating adhesive, 5 to 10 parts of bamboo liquefied phenolic resin, 1 to 2 parts of an air entraining agent, 1 to 2 parts of dispersant, 0.5 to 1 part of a foam breaker and 100 to 200 parts of water. The interface agent can be applied to binding new and old concrete, and has the advantages of high bonding strength,high freeze-thaw resistance and high air permeability.
