Problems solved by technology

These traditional SBC formula hot melt adhesives have the following problems for low-temperature use areas: low-temperature lamination restrictions, general express lamination temperature 0-45°C, logistics waybill lamination temperature -5-45°C
However, the limitation of low-temperature bonding will lead to the following problems: 1) The use area is limited, resulting in the cold winter in the north or unheated areas cannot be used in winter, there is a risk of loss of adhesion
2) Hidden dangers such as leakage of customers' personal privacy and theft of express items, resulting in customer complaints
3) The development of logistics enterprises is limited, and there is always no feasible solution for low-temperature bonding temperature

Abstract

The invention discloses an environment-friendly logistics hot melt adhesive capable of fitting at low temperature, a preparation method of the hot melt adhesive and an application of the hot melt adhesive. The hot melt adhesive is prepared from, in weight percent, 10-30% of naphthenic oil, 15-35% of high-molecular polymers, 5-25% of low-molecular toughening agents, 5-20% of liquid tackifying resin, 30-60% of tackifying resin and 0.2-0.8% of antioxidants. According to the hot melt adhesive, the fitting temperature of an express PE (polyethylene) seal is low to 10 DEG C below zero, the fitting temperature of a logistics waybill is low to 15 DEG C below zero, the fitting temperature of packing list enclosed is low to 15 DEG C below zero, the fitting temperature of an express file seal is lowto 20 DEG C below zero, and the fitting temperature of the hot melt adhesive is lower than 10 DEG C that of a traditional adhesive matched by SBC (styrene block copolymer). The hot melt adhesive overcomes the shortcomings of low-temperature fitting of the hot melt adhesive in the prior art.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a hot-melt adhesive, in particular to a logistics-friendly hot-melt adhesive capable of laminating at low temperature and its preparation method and application.
