Washable hot melt adhesive and application thereof

The invention discloses a washable hot melt adhesive and application thereof. The hot melt adhesive is composed of the following raw materials by mass percentage: 30-80% of high-acid value resin; 0-40% of a plasticizer; 10-40% of a thermoplastic high polymer; and 0-1% of an antioxidant. The hot melt adhesive provided by the invention selects high-acid value resin as the tackifier, which contains carboxyl or hydroxyl and other hydrophilic functional groups, and can rapidly react with alkaline water so as to destroy the structure of the hot melt adhesive and lower the stripping force of the hot melt adhesive. The hot melt adhesive is partially dissolved and dispersed into small solid particles so as to completely break away from an adherend, thus being easily removed from the surfaces of PET, PP, PE, glass, ceramics, metals, leather, wood, paper products, plastic products, textile products or others. The washable hot melt adhesive provided by the invention has the bonding performance of conventional hot melt adhesives, and has the advantages of strong initial adhesion, environmental protection and safety, the preparation process is simple, the requirements for the process and equipment are low, the production efficiency is high, and the production cost is low.

Self-oxygen-supply hollow Prussian blue nanoparticle as well as preparation method and application thereof

The invention discloses a self-oxygen-supply hollow Prussian blue nanoparticle and a preparation method and application thereof. The self-oxygen-supply hollow Prussian blue nanoparticle is provided with a hollow Prussian blue nanoparticle body, hemoglobin and IR783 are loaded on a mesoporous shell layer and an internal hollow structure of the hollow Prussian blue nanoparticle body, the drug loading capacity of the hemoglobin is 61.5%-63.5%, and the drug loading capacity of the IR783 is 24.2%-27.5%. The self-oxygen-supply hollow Prussian blue nanoparticle loaded with hemoglobin and IR783 prepared by the invention can improve the condition of insufficient oxygen supply in photodynamic therapy; in addition, since the half-life period of active oxygen generated by the photodynamic therapy is very short and the active oxygen is effective only in a relatively short distance, loading of IR783 with a mitochondrial targeting function is conducted in the invention, the self-oxygen-supply hollow Prussian blue nanoparticle body loaded with hemoglobin and IR783 is conveyed to mitochondria, so a mitochondrial function is destroyed, photodynamic therapy effect is remarkably improved, and tumor cell apoptosis is promoted.
