TABLE 1 test results of the non-reactive polyolefin Hot melt adhesive Properties
And (4) conclusion: as can be seen from examples 1 to 3, increasing the amount of wax added and decreasing the amount of APAO added reduced the 180 ℃ melt viscosity of the hot melt adhesive, but the adhesion to the substrate decreased, the amount of addition reached 10 parts by mass, and the adhesive tape lifted up and dropped off after being dipped in alkali solution, and was considered to be an unacceptable product. As can be seen from examples 4 to 5, the amount of the polypropylene homopolymer has a large influence on the overall softening point, and the softening point is remarkably lowered when the amount is less than 30 parts by mass, while the viscosity is greatly increased when the amount is more than 30 parts by mass.
