Background technology
At present adhesive is based on oil-based solvent type, but because of its organic solvent contained most of inflammable and explosive,
Volatile, abnormal smells from the patient is big, pollute environmental effect health.
Though Aqueous Adhesives is a kind of Environment-friendlyadhesive adhesive, but Aqueous Adhesives is basic medium with water, tool
There is drying time long, poor to apolar surfaces bond effect, the shortcoming of poor water resistance.
Tradition adhesive is prepared with petroleum resources and synthetic chemical for raw material mostly, but along with petroleum resources
Exhaustion and the enhancing of people's environmental consciousness so that tradition adhesive receive certain restriction.Therefore may be used
Regenerated resources, biomaterial are increasingly subject to people's attention as industrial chemicals.
Summary of the invention
