Curing agent A in B1：Curing agent B：Curing agent C=2.5:1:1；
Curing agent A in B2：Curing agent B：Curing agent C=4:1:1；
Curing agent A in B3：Curing agent B：Curing agent C=7:1:1；
Curing agent A in B6：Curing agent B：Curing agent C=16:1:1；
By data comparison it is found that the content with curing agent A increases, the heat resistance and Nai Gao of embodiment B1, B2, B3
It is qualification that the performance of warm high humidity, which is all graded all, and the heat resistance of embodiment B4 and the performance of high-temp resisting high-humidity resisting are all rated and do not conform to
Lattice.
Comparative example B1~B6, it is known that, curing agent A is in 5%~7% range in content, and corresponding curing agent B and
Curing agent C controls are in 1%~2%, in the binder building-up process for hot melt adhesive film that the design can be made, solidification path
Degree is suitable, and it is appropriate to be crosslinked between the strand of the binder for hot melt adhesive film, therefore has toughness, in the rich test of song
In, embodiment B1~B3 is qualification；Instead because not between curing agent A, curing agent B and curing agent C in embodiment B4~B6
Relationship there is no limit good, and ratio is excessively close or difference is too big, therefore affects the crosslinking situation of binder, under toughness
Drop.
Conclusion：
The content of curing agent A cannot be excessive, otherwise can influence the heat resistance of binder and the performance of high-temp resisting high-humidity resisting.
Curing agent A is controlled in content in 5%~7% range, curing agent B and curing agent C controls in 1%~2%, this
The binder of design can reach best cross-linking effect, there is preferable toughness.
Embodiment C:
The method for preparing binder of the prior art is by the saturated polyester 1 of 15%-20%, 20%-25% saturated polyesters 2
It is uniformly mixed with solvent dissolving, 40% fire retardant and surplus filler organic solvent；It is eventually adding 10% curing agent and disperses, make
It is standby go out embodiment C1.
Embodiment A1 and above-described embodiment C1 are subjected to above-mentioned 9 performance comparisons, table 5 is made.
5 embodiment A1 of table and embodiment C1 performance comparison tables
It can be seen that although the embodiment C1 of the prior art is qualified mark in terms of performance is appearance, carries on the back viscous, adhesive force
It is accurate；And standard is all not achieved in high-temp resisting high-humidity resisting, thermal shock, bent rich test and snap connector test performance, it is unqualified；
Reason is that curing agent causes the curing degree of material incomplete without paying attention to the proportioning between curing agent in the prior art；Gu
Agent is likely to occur excessively or reactivity is excessively active, causes crosslink density excessive, keeps the reticular structure in material excessive, be in
Reveal hard and crisp situation；And curing agent is very few or selects the too low curing agent of reactivity, then can cause material occur it is soft and
Weak situation；And C can be obtained through this embodiment, the A1 in the design, using saturated polyester A, saturated polyester B as main tree
Fat, and carry out corresponding performance using saturated polyester C and fill a vacancy；The proportioning of rational allocation curing agent is curing agent A：Curing agent B：Gu
Agent C=5:2:2, the ratio of different curing agent has utilization to avoid hardener dose excessive or very few situation at successively decreasing.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and it cannot be construed to limiting the scope of the invention in any way.Based on the explanation herein, the technology of this field
Personnel would not require any inventive effort the other specific implementation modes that can associate the present invention, these modes are fallen within
Within protection scope of the present invention.
