Abstract

The invention provides a hot-melt pressure-sensitive adhesive special for a foot patch bottom support, which at least comprises the following preparation raw materials in parts by weight: 20-50 partsof a thermoplastic elastomer, 40-60 parts of tackifying resin, 10-30 parts of a plasticizer, 1-5 parts of an antioxidant and 0-3 parts of an auxiliary antioxidant.

Description

technical field [0001] The invention belongs to the technical field of medical polymer materials. Specifically, the invention relates to a special hot-melt pressure-sensitive adhesive for foot pads and soles and a preparation method thereof. Background technique [0002] As early as in the "Huangdi Neijing", there was "there are evils, stains with sweat". It can be seen that bath therapy had been advocated at that time. The "Fifty-two Prescriptions" unearthed from the Mawangdui Han Tomb contains "prescription for infantile epilepsy, take thundertail and three fruits, and mix it with pig decoction. For small babies, use half a bucket of water, for older ones, take one bucket of water, and three parts. Take a part of it and put it in the water, and scratch it to bathe it. It means to use traditional Chinese medicine foot therapy to treat children with frequent diseases. "Treatise on Febrile Diseases" etc. have just recorded many Chinese medicine foot therapy formulas for trea...
