Abstract
The invention relates to the technical field of hot-melt pressure-sensitive adhesives, in particular to a special hot-melt pressure-sensitive adhesive with ultralight unwinding force for sports bondages. The hot-melt pressure-sensitive adhesives is prepared from raw materials in parts by weight as follows: 30-60 parts of a styrene block copolymer, 20-30 parts of tackifying resin, 10-15 parts of asoftener and 1-3 parts of an antioxidant, wherein the styrene block copolymer is selected from one or more of SEBS, SBS, SIS, SBR and SEPS. According to the special hot-melt pressure-sensitive adhesive with ultralight unwinding force for sports bondages, under the joint action of preparation raw materials of the hot-melt pressure-sensitive adhesive, the prepared hot-melt pressure-sensitive adhesive has high initial adhesion as well as the ultralight unwinding force when used for sports bandages.
Description
technical field [0001] The invention relates to the technical field of hot-melt pressure-sensitive adhesives, and more specifically, the invention relates to a special hot-melt pressure-sensitive adhesive for sports bandages with ultra-light unwinding force. Background technique [0002] Physical exercise can not only enhance physical fitness, optimize metabolism, but also relieve stress, burn fat and shape your body. However, if you are a little careless, it may also lead to sports injuries, among which the most common tissue injuries around the joints. In order to prevent sports injuries, many people choose to use sports bandages to protect their joints. Most sports bandages are made of strong high-elastic cloth, which is then coated with pressure-sensitive adhesive and wound up. During use, joint swelling can be relieved by wrapping a bandage around the joint. At present, there is a new demand for sports bandages in the market. When athletes use sports bandages during ...
