Abstract

The invention belongs to the technical field of cooling materials, and proposes a hydrogel-cotton composite material for cooling clothes, which is composed of the following components in parts by weight: 5-50 parts of cotton, 5-30 parts of hydrophilic polymer, water-soluble single Body 10-50 parts, initiator 0.01-2 parts, cross-linking agent 0.1-2 parts. The present invention also proposes a method for preparing a hydrogel-cotton composite material for cooling clothing, comprising the following steps: soaking the cotton with a hydrophilic polymer, freezing, and thawing after containing water-soluble monomers and hydrophilic polymers , initiator, and cross-linking agent in the mixed aqueous solution and then taken out, initiated by ultraviolet light at room temperature or polymerized under the condition of thermal initiation at 40-80°C, and freeze-dried to obtain the hydrogel-cotton composite material for cooling clothes. The invention solves the problems in the prior art that the hydrogel particles or powders of the cooling clothes are unevenly dispersed, easy to ooze out, and pollute the environment.

Description

technical field [0001] The invention belongs to the technical field of cooling materials, and relates to a hydrogel-cotton composite material for cooling clothes and a preparation method thereof. Background technique [0002] Summer is scorching hot and the heat is unbearable. The scorching sun and continuous high temperature will cause serious harm to people, such as heat stroke, cerebrovascular disease and heat stroke. Ordinary people can choose to stay in a cool place or use air conditioners and electric fans to cool down, but there are some special industries such as construction, road administration, transportation and metal smelting practitioners, military personnel, policemen who are training or performing duties in the field or outdoors, and People who exercise outdoors have to work hard for a long time in the scorching heat under the scorching sun. Even if some heatstroke prevention and cooling measures are taken, heatstroke phenomenon still inevitably occurs. It i...
