Reaction type non-asphalt base waterproof composition

The present invention provides a reaction typ enon-asphalt base waterproof composition. The composition is characterized by comprising the following raw materials in parts by weight: 20-60 parts of rubber; 20-40 parts of a tackifier; 8-15 parts of a softening agent; and 0.2-4 parts of a waterproof bridging agent. One end of the waterproof bridging agent can be combined with C=C double bonds or carboxyl (-COOH) of rubber, and the other end of the waterproof bridging agent can be bonded with acid radicals generated after cement is hydrated. A waterproof bridge is built, and very strong adhesive force is generated, so that glue and the cement are tightly bonded to form a firm waterproof layer.
