Document Type and Number:
WIPO Patent Application WO/2023/130609
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of pressure-sensitive adhesives, in particular to a water-resistant and sweat-resistant hot-melt pressure-sensitive adhesive, and a preparation method therefor and the use thereof. The water-resistant and sweat-resistant hot-melt pressure-sensitive adhesive is mainly prepared from the following components in parts by weight: 5-35 parts of a styrene block copolymer, 5-25 parts of a polyurethane elastomer, 10-30 parts of a plasticizer, 30-50 parts of a tackifying resin, 0-1 part(s) of an antioxidant, 2-30 parts of a water-absorbing high polymer, and 1-10 parts of a polyphenol biomimetic material. In the present disclosure, by means of the cooperation of all the components and the use of a certain amount of the styrene block copolymer and the polyurethane elastomer in cooperation, it is ensured that the pressure-sensitive adhesive has both an improved viscosity and improved cohesive strength and maintains excellent adhesion to skin without leaving any adhesive residue; and by introducing a certain amount of the water-absorbing high polymer and the polyphenol biomimetic material, the water resistance and sweat resistance of the hot-melt pressure-sensitive adhesive are improved, and the hot-melt pressure-sensitive adhesive is also ensured to be free from sensitization and irritation to skin.
