Embodiment 1

[0039] This embodiment relates to a heat-resistant heat-seal adhesive used in a high-speed drug blister packaging machine for pharmaceutical blister packaging. The specific formula is shown in Table 1. The preparation method includes the following steps:

[0040] (1) Put all the solvents into the reactor according to the ratio and stir;

[0041] (2) Keep stirring and put the modified polyolefin and modified epoxy into the reactor in turn, and stir for 1-2 hours;

[0042] (3) Slowly put the auxiliary agent into the reaction kettle after mixing uniformly, and stir at high speed for 0.5-1 hour;

[0043] (4) When the mixture is evenly mixed, stop and mature for 10-12 hours;

[0044] (5) Measure the solid content and adjust it to the theoretical value;

[0045] (6) Stir slowly again for 1-2 hours, cool, filter with 250 mesh filter, weigh and pack.

Embodiment 2-5

[0047] Examples 2-5 respectively relate to a heat-resistant heat-seal adhesive used in a high-speed packaging machine for blister packaging of medicines. The preparation method thereof is the same as that of Example 1. The specific formula is shown in Table 1.

Abstract

The invention provides a high temperature-resistant heat-sealing adhesive for a high-speed medicine packaging machine for medicine blister packaging. The high temperature-resistant heat-sealing adhesive comprises, by mass, 20-39.9% of modified polyolefin resin, 10-20% of modified epoxy resin, 50-60% of a solvent and 0.1-0.5% of an assistant. A preparation method of the high temperature-resistant heat-sealing adhesive comprises the following steps: S1, adding the solvent into a reaction kettle, performing stirring to achieve uniform mixing, sequentially adding the modified polyolefin resin andthe modified epoxy resin while stirring, and stirring and uniformly mixing the solvent, the modified polyolefin resin and the modified epoxy resin; S2, adding the assistant to a mixed solution obtained in step S1, performing high-speed stirring to achieve uniform mixing, and performing downtime curing; and S3, measuring the solid content, adjusting the solid content to a theoretical value, and performing stirring, cooling and filtering. Compared with heat-sealing adhesives in the prior art, the heat-sealing adhesive in the invention has the following advantages: no leakage sealing, no scorching crease marks and no peculiar smell are achieved during high-temperature and high-speed sealing using the medicine packaging machine; the heat-sealing strength is high, so product demands are met; anadhesive layer has a good stability, and the strength of a coating film does not change after the coating film is stored for one year; and the heat-sealing adhesive has a wide application range.

Description

Technical field [0001] The invention relates to the technical field of heat-resistant heat-sealing adhesives in pharmaceutical blister packaging, in particular to a heat-resistant heat-seal adhesive used in a high-speed pharmaceutical packaging machine for pharmaceutical blister packaging and a preparation method thereof. Background technique [0002] With the continuous rapid development of my country’s economic situation and the continuous improvement of people’s living standards, the pharmaceutical industry has developed relatively rapidly. At the same time, modern machinery is developing in the direction of high precision, high speed and low cost. These factors have directly promoted the rapid development of pharmaceutical companies. development of. In order to make full use of the pharmaceutical equipment of pharmaceutical companies, high-speed drug packaging is the most direct, efficient and convenient way, but it also comes with some inevitable problems. [0003] When the co...
