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.

Description

technical field

[0001] The invention relates to a hot-melt adhesive and a preparation method thereof, in particular to a wet-strength hot-melt adhesive for disposable sanitary products and a preparation method thereof. Background technique

[0002] In recent years, with the development of the economy and the improvement of people's living standards, disposable sanitary products have entered thousands of households. 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 for the processing of disposable sanitary products, however, the gene...
