Method for preparing-environmental-protection sponge adhesive

The invention provides the producing method of a kind of environmental protection sponge mucilage glue agent which compounded from chemical raw materials as polyether polyol, tolylene diisocyanate (TDI) and stannous caprylate. Its producing method is simple, technics is convenient, and the production cost is low. After the agent felted into shape, the time is longer, the pull is stronger. The original shape finalized design of the product is good, which can ensure the quality of the product, and can meet the requirement of environmental protection. Besides in the using course, it can automatically control the shape felting time of the mucilage glue agent. Especially it doesn't use deleterious substance as methylene chloride in its preparation process, so it won't cause deleterious pollution to environment.
