Binding is the binding of the cover and the inner album (the book block). The processing of paper between two monomers with similar or identical polarity can be seen as a purely physical behavior, unlike plastic film, which is the result of comprehensive physical and chemical behavior.
The physical behavior of glue binding is the republic of the second movement. The first time is the application of glue. The second time is the cover.
1. Glue-glue hot melt adhesives are designed based on the production process (see Figure 6):
Adhesive hot melt adhesives include:
· Primary adhesive resin
· Tackifying resin
·Modification modifier I
·Modification modifier II
·Anti-aging agent K
2. Adhesive hot melt adhesive use process (see Figure 7):
Hot melt adhesive synthesis → Hot melt adhesive coating of book blocks → Cover
3. Adhesive hot melt adhesive use conditions (see Figure 8):
Figure 8 Adhesive hot melt adhesive use conditions
4. The technical core of hot melt adhesive for glue binding:
Penetration flow in the back groove of a pair of books;
2 Fold using toughness shear strength.
5. Adhesive hot melt adhesive features (see Figure 9):
