AI Technical Summary

Problems solved by technology

When the existing hot melt adhesives for hygiene materials are placed under high temperature conditions for a long time, heat aging will inevitably occur, resulting in a decrease in mechanical bonding performance, shortening the service life of hot melt adhesives, and making hot melt adhesives and related products in storage. And during the transportation process, due to the high temperature aging problem, the health material products cannot be used normally, resulting in a large loss

Abstract

The invention discloses a heat-aging-resistant hot melt adhesive based on SiO2-g-PS nanoparticle modification and a preparation method thereof, the thermal aging resistant hot melt adhesive is prepared from the following components by weight: 25-35 parts of a thermoplastic elastomer, 12-16 parts of naphthenic oil, 0.1-0.5 part of an antioxidant, 40-50 parts of hydrogenated petroleum resin, 8-12 parts of liquid rubber, and 0.5 to 2 parts of composite nanoparticles with a SiO2-g-PS core-shell structure. Mainly on the basis of the existing hygienic material hot-melt pressure-sensitive adhesive, PS grafted modified nanoparticles are added to improve the thermal stability of the hot-melt adhesive, reduce the thermal aging phenomenon of the hot-melt adhesive when the hot-melt adhesive is placed for a long time at a high temperature, and prolong the service life of the hot-melt adhesive. The possible loss of the hot melt adhesive and related products in the storage and transportation processes is reduced.

Description

technical field [0001] The invention relates to a hot melt adhesive technology, in particular to a 2 - g-PS core-shell structure composite nano particles so as to realize high adhesive strength hot melt adhesive with anti-heat aging function and preparation method thereof. Background technique [0002] Hot melt adhesives for hygiene materials are mainly used in the non-woven fabric bonding industry, and the most important applications are in baby diapers, pull-up pants, adult diapers, sanitary napkins, panty liners and other sanitary products. When the existing hot melt adhesives for hygiene materials are placed under high temperature conditions for a long time, heat aging will inevitably occur, resulting in a decrease in mechanical bonding performance, shortening the service life of hot melt adhesives, and making hot melt adhesives and related products in storage. And during the transportation process, due to the high temperature aging problem, the hygiene material product...
