The invention provides a waterproof
coating capable of chemical crosslinking and physical
mortise and tenon with
cement. The waterproof
coating is characterized by comprising the following raw materials by weight: 20-50 parts of a
synthetic rubber latex, 20-50 parts of emulsified
asphalt, 0.5-2 parts of a functional additive and 0.5-2 parts of a dispersant, 20-40 parts of a filler and 10-25 parts of water. The principle is that through
coupling effect of the functional additive, part of the molecules in the
synthetic rubber and most molecules in the
asphalt couple into large molecules with reaction activity; when the large molecules contact with a
base plane, the non-reactive molecule segments of the rubber and
asphalt and the
base plane form physical adsorption, and the molecular segments with reaction activity conduct react with the
base plane to form
chemical bond effect, so as to generate strong
adhesive force; and after bonding, the
coating is hardly influenced by environmental factors. Therefore, the waterproof coating provided by the invention has excellent waterproof performance.
