Abstract

The invention relates to a hot melt adhesive for paper diaper. The hot melt adhesive is prepared from, by weight, 26-35 parts of styrene-butadiene-styrene polymer, 10-15 parts of polystyrene-polyisoprene-polystyrene, 20-22 parts of tackifying resin, 6-8 parts of microcrystalline wax, 5-15 parts of liquid state plasticizer, 5-12 parts of nanometer activated carbon powder, 1-2 parts of vegetable oil and 0.5-1 part of antioxidant. The invention further relates to a preparation method of the hot melt adhesive for the paper diaper.

Description

technical field [0001] The invention relates to a hot melt adhesive for paper diapers and a preparation method thereof. Background technique [0002] Hot melt adhesive, also known as hot melt adhesive, is a solvent-free thermoplastic solid adhesive. When in use, it obtains fluidity after heating and melting, infiltrates the surface of the adherend, and realizes bonding by hardening or reaction solidification after cooling. Compared with other adhesives, hot melt adhesive has fast bonding speed, can be cured within a few seconds after heating and melting, and can be solidified when it touches the surface of the adherend. It is suitable for automatic and continuous production processes; it does not contain solvents, is non-toxic to the human body, and is Pollution of the environment, convenient transportation and storage; can bond a variety of materials, can be used to bond wood, paper, metal, glass, plastic, ceramics, clothing, electronic components, packaging materials, etc...
