There are three the shortcomings that current techniques, is main: (1), adhesive be not full aqueous systems because in curing agent still include acetic acid
Ethyl ester still can be evaporate into air in use, threaten the occupational safety and health of worker, in storage and transport still
So there is biggish security risk；(2), using complex process, two-component glue must stirred according to a certain ratio before
Mixing mixing could use, this causes more to bear to production management；(3), using limited time system, two-component glue mixes it
After begin to that chemical crosslink reaction occurs, so most of glue brands producer all provide after glue mixing necessary 2 hours
It is inside finished, otherwise glue can be solidified and is difficult with, and must be scrapped more than the glue that the time is not finished.
Summary of the invention
A kind of cold-gluing shoes one pack system water is provided it is an object of the invention to overcome above-mentioned the deficiencies in the prior art place
Property polyurethane glue, the aqueous polyurethane glue are full aqueous systems truly, very VOC free (organic volatile

At least one of organic silicon defoaming agent BYK-028 Bi Ke company, organic silicon defoaming agent BYK-024, Bi Ke company.More preferably
Ground, the defoaming agent are selected from Rhodia's mineral oil defoaming agent RHODOLINE 642NI.
As the preferred embodiment of aqueous polyurethane glue of the present invention, the wetting dispersing agent is anionic profit
The mixture of humectant and polymer electrolyte wetting dispersing agent, the average molecular weight of the anionic wetting agents are the institute lower than 1000
The average molecular weight for stating polymer electrolyte wetting dispersing agent is 1000-10000.The two plays synergistic effect, improves the water jointly
The stability of property polyurethane glue.
As the preferred embodiment of aqueous polyurethane glue of the present invention, the anionic wetting agents are dodecane
At least one of base sodium sulfonate, sodium metnylene bis-naphthalene sulfonate, dispersing agent MF, nekal.
