Technical Field

The invention relates to the technical field of hot melt adhesives, in particular to a hot melt adhesive for bonding EPE pearl wool.

Background

The EPE pearl cotton is a non-crosslinked closed-cell structure, is also called polyethylene foam cotton, is a novel environment-friendly packaging material, and is beneficial to environmental protection and recycling. It is made up by using low-density polyethylene through the process of physical foaming process to produce countless independent bubbles. Overcomes the defects of easy breakage, deformation and poor restorability of common foaming glue. The packaging material has the advantages of water resistance, moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, cyclic reconstruction, environmental protection, strong impact resistance and the like, also has good chemical resistance, and is an ideal substitute of the traditional packaging material. The packaging material is widely applied to packaging of various products such as automobile cushions, throw pillows, electronic appliances, instruments, computers, sound equipment, medical appliances, industrial control cases, hardware and lamp decorations, artware, glass, ceramics, household appliances, spraying, furniture and furniture, wine, resin and the like, and packaging of various high-grade fragile gift packages, hardware products, toys, melons and fruits, inner packages of leather shoes, daily necessities and the like. After the colored antistatic agent and the flame retardant are added, the antistatic flame retardant has more remarkable performance, is not bright and beautiful in appearance, and effectively avoids static electricity and ignition. The EPE and various fabric adhesive products are good interior decoration materials of various vehicles and living rooms, and the EPE pearl cotton and aluminum foil or aluminum-plated film composite products have excellent infrared ray and ultraviolet ray resisting capability and are necessary articles for shading the sun of chemical equipment refrigerators and camping equipment automobiles.
