The invention adopts styrene-acrylate emulsion as a waterproof building coating prepared by single-component high molecular polymer, the waterproof building coating adopts single-component styrene-acrylate emulsion to prepare the waterproof building coating, the preparation process can be simple, the cost is reduced, but the single-component styrene-acrylate emulsion coating has the problems of poor binding force with concrete, easy falling and instability and is not suitable for being used in the environment where underground moisture is easy to form condensed water, but the applicant discovers that the problem can be perfectly solved by adding a certain amount of diethylene glycol dibenzoate and three alcohol ether monomers with specific proportions into the single-component styrene-acrylate emulsion, and supposedly the possible reason is that the added diethylene glycol dibenzoate can generate synergistic action with three alcohol ether mixtures, the styrene-acrylate molecule, The dispersibility and compatibility of wollastonite and titanium dioxide promote the interaction of styrene-acrylate long-chain polymer, fibrous wollastonite and granular titanium dioxide to form a uniform and mutually-interlaced complex structure, and the applicant speculates that adequate complementary synergy can be generated between the rutile type titanium dioxide, the needle-shaped wollastonite and the flexible styrene-acrylate molecules in the interlaced complex structure, so that the mechanical strength of the coating is obviously enhanced; in addition, the applicant speculates that condensed water generated in the wall can be quickly adsorbed and locked due to the fact that ether bonds are rich in the three alcohol ethers and the diethylene glycol dibenzoate in the staggered complex structure, the pressure resistance effect of the coating on water and the adsorbability of the coating on the wall are enhanced, the staggered complex structure is beneficial to the fact that the coating is not prone to bulge and crack, the use is durable, and the painting adaptability and the stability of the coating are improved. The applicant also found that the acid-base corrosion resistance of the waterproof building coating is very excellent, and presumably the particularity of the system is that the long-chain polymer, the fibrous wollastonite and the granular titanium dioxide interact to form a uniform and complex structure which can be staggered mutually, so that the waterproof building coating has very high compactness, can eliminate corrosion caused by the corrosion of acid-base gas or liquid to the waterproof building coating, and has excellent acid-base resistance, and simultaneously has very good covering power.
