ABSTRACT: Due to large volume and high hardness of thermal
insulation materials mostly used in high temperature fields, a composite
cooling powder and its thixotropic hydrogel for thermal protection are
presented. The core of composite cooling material powder is super absorbent
polymer, composing with metal salt, polysaccharide hydrosol and inorganic
particles and other modifiers through a series of composite process, which can
be easily stored for a long time. When needed, the powder can be mixed with
water to obtain a kind of thixotropic hydrogel in a very short time.
Experimental results show this thermal protection technology with thixotropic
ability has excellent thermal protection performance, meanwhile flexible,
adhesive and low cost, which exerts instantaneous cooling, efficient thermal
protection and long-lasting flame-retardant protection.
