The ceramic polyolefin material not only can resist fire and be porcelainized, but also has excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of wire and cable materials, in particular to a fly ash-based ceramic polyolefin composition, a ceramic polyolefin material and a preparation method and application thereof. Background technique [0002] Ceramic polyolefin materials have the excellent properties of ordinary polymers at room temperature, and can form a self-supporting ceramic structure at high temperatures, which can protect the insulated wire core and ensure the normal operation of the line system in the event of a fire. Far-reaching impact, with broad prospects for development. [0003] At present, the commonly used porcelain filler has the disadvantage of high price. [0004] CN103509237B discloses a rapid ceramic refractory cable material, which is prepared from the following component raw materials in parts by weight: ethylene-vinyl acetate copolymer (EVA) 40-50, polyethylene 30-40, natural rubber 20-35, Styrene butadiene rubber 30-40,...
