The modified MF resin includes the raw material of following parts by weight:
Hot-fusible pressure-sensitive adhesive made from embodiment 1-5 and comparative example 1-4 is subjected to hot-fusible pressure-sensitive adhesive and courier packages' outer layer
Bond properties test, shown in test result is as follows:
The testing standard of the melt viscosity is carried out according to " measurement of HB/t3660-1999 hot melt adhesive melt viscosity "
Test；The testing standard of the peel strength is according to " 180 ° of peeling strength test methods of GB/T 2792-1998 pressure-sensitive tape "
It is tested；Stripping damage temperature under the high temperature and under low temperature is according to " 180 ° of GB/T 2792-1998 pressure-sensitive tape strippings
From Strength Testing Methods " it is tested, it is tested under the peel strength of 6.0kN/m at how many temperature and peeling occurs.
By above-mentioned data it is found that melt pressure sensitive glue-line produced by the present invention has cohesive force height, the good property of weatherability
Can, it solves adhesive label and is easy to happen in use in summer or winter and stick up mark or fall the problems such as marking.
And comparative example 1 and comparative example 2 are using single liquid tackifying resin, the melting of hot-fusible pressure-sensitive adhesive obtained is viscous
Degree and peel strength are lower, and the stripping damage temperature under high temperature is lower, and the stripping damage temperature under low temperature is higher, illustrate this
Invention is compounded by using rosin resin with GT-30A type liquid terpene resins as liquid tackifying resin, can dramatically increase hot melt
The viscosity of pressure sensitive adhesive, change hot-fusible pressure-sensitive adhesive holds viscosity, cohesive performance, and it is viscous under hot weather or low temperature environment to improve it
Stability is closed, it is non-aging, being not easy to become fragile falls off, to hot, ice cold temperature adaptability is good.
And the C5 Petropols of comparative example 3 are not modified, the melt viscosity of hot-fusible pressure-sensitive adhesive obtained and removing are strong
Degree is lower, and the stripping damage temperature under high temperature is lower, and the stripping damage temperature under low temperature is higher, illustrates by using this hair
The petroleum resin modified method of bright C5 is modified, and can improve the softening point of C5 Petropols, improves adhesiveness, weatherability and phase
Capacitive, and then improve compatible dispersibility of the C5 Petropols in hot-fusible pressure-sensitive adhesive, improve hot-fusible pressure-sensitive adhesive adhesive strength and
Weatherability.
And it is modified in the MF resin modified of comparative example 4 using styrene, the melt viscosity of hot-fusible pressure-sensitive adhesive obtained
It is lower with peel strength, and the stripping damage temperature under high temperature is lower, the stripping damage temperature under low temperature is higher, and explanation passes through
Blending and modifying is carried out to MF resin using caprolactam and NaOH powder, improves the methylolation degree of MF resin, and then improve
The flexibility and adhesiveness of MF resin and hot-fusible pressure-sensitive adhesive, are less prone to crack phenomenon, are less prone to and warp, fall phenomena such as marking,
Weatherability is preferable.
Above-described embodiment is the preferable implementation of the present invention, and in addition to this, the present invention can be realized with other way,
Do not depart under the premise of present inventive concept it is any obviously replace it is within the scope of the present invention.
