Problems solved by technology

Hot-melt adhesive is a single-component anhydrous, solvent-free, solid at room temperature, adhesive that can bond the surface of materials after melting at high temperature. Melt adhesive has been widely used in many fields such as food packaging, book binding, furniture industry, cable accessories, disposable sanitary products industry, etc., because hot melt adhesive is safe and environmentally friendly, non-toxic and harmless, suitable for high-speed production, and is widely used Adhesives used in the processing of disposable sanitary products, however, the general adhesives on the market have some defects in some stations, which caused complaints from downstream consumers when using them
[0003] The current adhesive technology solutions on the market are unbalanced in the bonding of polar materials and non-polar materials, especially after the materials are wet, there is often a bond between polar materials and non-polar materials sharp drop in intensity

Embodiment 1

[0033] Naphthenic oil (4010 from Karamay), which accounts for 25% of the mass of the hot-melt adhesive, SIS1209, which accounts for 19% of the mass of the hot-melt adhesive, SBS188, which accounts for 5% of the mass of the hot-melt adhesive, and additive resin, which accounts for 5% of the mass of the hot-melt adhesive, Mix 0.7% antioxidant of hot melt adhesive evenly, heat to 140-150°C, continuously stir and evacuate to -0.08mpa, until completely melted, add C5 petroleum resin (Angstrom Kesen 5600), keep the heating temperature at 130-140°C, stir evenly, wait until completely melted, vacuumize until there are no bubbles, and the resulting mixture is a wet-strength adhesive for disposable sanitary products.

[0034] The hot melt adhesive prepared in this example is suitable for spraying and scraping gluing devices. The specific glue temperature is 150-155°C for the glue tank, 155-160°C for the throat, 160-165°C for the nozzle, and the glue amount is 3g / m 2 , the bonding stre...

Embodiment 2

[0038] Naphthenic oil (4010 from Karamay), which accounts for 30% of the mass of the hot melt adhesive, SBS1301 rubber which accounts for 3% of the mass of the hot melt adhesive, SIS1209 rubber which accounts for 10% of the mass of the hot melt adhesive, and SIS1126 which accounts for 3% of the mass of the hot melt adhesive Mix rubber and 0.3% antioxidant (1010) by mass of hot melt adhesive evenly, heat to 140-150°C, and continuously stir and vacuumize to -0.08mpa. After completely melting, add 15% of hot melt adhesive mass C5 petroleum resin, add rosin resin PER-100L accounting for 33.7% of the mass of the hot melt adhesive, add additive resin accounting for 5% of the mass of the hot melt adhesive, keep the heating temperature at 120-130°C, stir evenly, wait until it is completely melted, and then vacuumize Until there are no air bubbles, the resulting mixture is a wet-strength adhesive for disposable hygiene products.

Abstract

The invention discloses a wet-strength hot-melt adhesive for a disposable hygienic product. The wet-strength hot-melt adhesive for disposable hygienic product is prepared from, by mass, 15-30% of high-molecular polymer, 40-60% of tackifying resin, 15-30% of naphthenic oil, 5-10% of auxiliary resin and 0.1-1.0% of an antioxidant. The high-molecular polymer is one or several of SBS, SIS, SBR, SEBS and SSBR, the tackifying resin is one or several of petroleum resin C5, petroleum resin C9 and modified rosin resin, and the auxiliary resin is high-polarity terpene-phenolic modified resin or maleic anhydride grafting resin. The wet-strength hot-melt adhesive is used for bonding moderate-polarity materials (wood pulp and wet-strength paper) and non-polarity materials (non-woven fabrics and PE films) in disposable hygienic product materials, and by means of the adhesive, the delaminating phenomenon caused after liquid absorbing of the product can be effectively reduced, the integrity of paper diapers is kept well, the problems of lumping, fracturing, leaking and the like of the product are avoided, and a child feels more comfortable, drier and smoother when wearing the product. The invention further discloses a method for preparing the wet-strength hot-melt adhesive for the disposable hygienic product.
