Abstract

The invention discloses an adhesive used for medicine blister packaging and a preparation method thereof. The adhesive is prepared from the following raw materials in parts by weight: 10-25 parts of acrylic copolymer resin, 4-10 parts of vinyl chloride copolymer resin, 3-10 parts of styrene copolymer resin, 0.8-1.5 parts of stearic acid, 10-15 parts of calcium carbonate, 3-7 parts of asbestos powder, 8-12 parts of white carbon black, 1-3 parts of barium laurate and 70-85 parts of mixed solvent. The adhesive used for medicine blister packaging and the preparation method have the beneficial effects that higher hot sealing adhesive strength and a wide hot sealing temperature range are provided through the mass-average molecular weight ranges and glass transition temperature ranges of raw materials used by the adhesive; all the indicators conform to the standards of national medicine packaging materials; the preparation method is simple and practicable; the adhesive is not only suitable for blister packaging but also suitable for polystyrene films and polystyrene composite materials.

Description

technical field

[0001] The invention belongs to the technical field of adhesives, and in particular relates to an adhesive for drug blister packaging and a preparation method thereof. Background technique

[0002] At present, pharmaceutical blister packaging and its composite flexible packaging have been widely used, not only in the field of pharmaceutical packaging, but also in the food and health care products industries. The so-called drug blister packaging is made by vacuum suction (blowing) or filling the drug in the molded blister, using an adhesive as a coating, using drug aluminum foil to cover the surface, and through pressure, at a certain temperature Under the condition of time, it is heat-sealed with the foam-forming substrate. The quality of pharmaceutical blister packaging depends not only on the materials used, but also on the adhesives used.

[0003] At present, adhesives for drug blister packaging include the following categories: 1) Pressure-sensitive adh...
