摘要:
Disclosed is a temperature-indicating composite material product and a manufacturing method and application thereof, the temperature-indicating composite material product comprising: a porous film (1), opaque to at least a portion of visible light or opaque to at least a portion of visible light and at least a portion of ultraviolet light; and a colored composite material layer (2) located at the lower surface of the porous film (1), wherein the colored composite material layer (2) comprises a macro-molecular connecting material, a crystalline material and a colorant. Preferably, the macro-molecular connecting material is a crosslinked pressure-sensitive adhesive material, wherein the crystalline material and the colorant are dispersed in the macro-molecular connecting material, and the macro-molecular connecting material is an amorphous material or has a melting point higher than that of the crystalline material. When heated and melted, the crystalline material may migrate into the porous film (1) and fill pores therein, making the porous film (1) transparent to visible light.

A thermal indicator, a thermal indicating composition (1), as well as two kinds of thermal indicating structures (11) are disclosed. The thermal indicator comprises an organic solid material (2) having a melting point higher than ambient temperature and a dye (3) which contacts the organic solid material (2) and is capable of being dissolved in the organic solid material (2) when the thermal indicator is heated to the melting point of the organic solid material (2). The thermal indicator, the thermal indicating composition (1), as well as these two kinds of thermal indicating structures (1) have simple structures and can be manufactured by a simple process. Furthermore, the existence of the dye (3) in its crystalline state offers significant resistance to UV radiation in outdoor applications.
摘要:
An insulating composition comprises: about 70-100 parts by volume of a polymeric material, about 5-30 parts by volume of a ceramic filler (2) which is surface-treated by a bifunctional coupling agent in an amount of about 0.1 wt % to about 4 wt % of the ceramic filler; about 0.1-5 parts by volume of a crosslinking agent; about 0-6 parts by volume of conductive powder (3); and about 0-6 parts by volume of ZnO whisker (4). A preparation method for making the insulating composition, an insulating article such as an electrical cable accessory, and a use thereof are provided.
