Solvent-free polyurethane aqueous dispersion

Abstract

The invention relates to a solvent-free polyurethane aqueous dispersion which comprises a heating tippet main body layer; a heating layer and a heating protecting layer are arranged on the positions of shoulders and cervical vertebra in the heating tippet main body layer; the heating layer is located between the heating tippet main body layer and the heating protecting layer; a controller and a battery fixing bag are arranged on one side of the heating tippet main body layer; self-adhesion surfaces are arranged on different sides of two ends on the bottom of the heating tippet main body layer;a temperature-controllable circuit and a high-capacity battery box are used as a heating source of the heating tippet main body layer; the temperature-controllable circuit and the high-capacity battery box are integrally designed. The solvent-free polyurethane aqueous dispersion has the advantages that heating temperature is uniform and comfortable, heating efficiency is high, patients sufferingfrom cervical spondylosis and scapulohumeral periarthritis can quickly achieve relieving and treating effects during the use process of the heating tippet capable of adjusting heating temperature in real time, and a certain adjuvant therapeutic effect for cervical vertebra and shoulders can be achieved through the combination of long-term use and regular heating effect.

Description

technical field [0001] The invention relates to the field of clothing, in particular to a solvent-free polyurethane aqueous dispersion. Background technique [0002] Cervical spondylosis and frozen shoulder are common phenomena in today's society, especially white-collar business personnel and middle-aged and elderly people who work in offices for a long time are the main targets of cervical spondylosis and frozen shoulder and tend to be normalized. When the disease occurs, the patient cannot work and study normally, and in more severe cases, the insufficient blood supply to the brain leads to syncope, and the arm cannot be raised normally until bed rest and hospitalization, which seriously affects people's normal life and work. Conventional warming shoulder pads only simply add a warming layer to the patient's cervical spine and scapula, and do not have a complete therapeutic effect on relieving the patient's pain. [0003] Therefore, how to effectively and reasonably reli...
