preparation example Construction
[0028] The present invention also provides a kind of preparation method of described adhesive composition, comprising:
[0029] The polyurethane binder and the polyvinyl acetate binder are mixed according to the ratio, and stirred evenly to obtain a binder composition.
[0030] According to the present invention, since the polyurethane adhesive is preferably Henkel 369 # glue. For polyurethanes, the polyvinyl acetate binder is preferably polyvinyl acetate emulsion type III glue, both of which are water-based binders, so they can be blended. But since the Henkel 369 # The viscosity of the glue is greater than the polyvinyl acetate emulsion type III glue, so special methods need to be used when stirring. According to the present invention, the stirring is specifically:
[0031] The mixture of the polyurethane binder and the polyvinyl acetate binder is placed in the first stirrer and stirred for 10 to 20 minutes to obtain the first mixed solution;
[0032] Put the first mixed...
Embodiment 1
[0036] Will Henkel 369 # 15 kilograms of glue and 15 kilograms of polyvinyl acetate emulsion type III glue produced by Haiyan Latex Factory are placed in a large glue barrel of 50 kilograms, and stirred with electric stirring for 10 minutes to obtain the first mixed solution; then pour the first mixed solution Put it into another glue bucket so that the upper and lower layers of glue can be fully blended, and then stir for 10 minutes before use.
Embodiment 2
[0038] Will Henkel 369 # 18 kilograms of glue and 20 kilograms of polyvinyl acetate emulsion type III glue produced by Haiyan Latex Factory are placed in a 50-kg large rubber bucket, and stirred with electric stirring for 10 minutes to obtain the first mixed solution; then pour the first mixed solution Put it into another glue bucket so that the upper and lower layers of glue can be fully blended, and then stir for 10 minutes before use.
