The invention discloses a ceramized
polyolefin material and a preparation method thereof, belonging to the field of
electric wire and cable materials. The ceramized
polyolefin material comprises the following
raw material components: 100 parts of an
ethylene-alpha-olefin
copolymer, 150-300 parts of ceramized
powder A, 20-100 parts of ceramized
powder B, 5-40 parts of a lubricating agent and 0.1-1 part of an
antioxidant, wherein the
ethylene-alpha-olefin
copolymer is one or more selected from an
ethylene and alpha-propylene
copolymer, an ethylene and alpha-butylene copolymer, an ethylene and alpha-hexylene copolymer and an ethylene and alpha-
octene copolymer; the ceramized
powder A is one or a combination of more than one selected from layered inorganic powder, fibrous inorganic powder and needle-like inorganic powder; the ceramized powder B is at least one selected from
borax,
ammonium borate, a
zinc borate and
boron frit,
phosphate glass powder with a
low melting point,
borate glass powder with a
low melting point and
silicate glass powder with a
low melting point; and the
antioxidant is at least one selected from 1010, 1076, 168, 626, 300 and DSTDP. The ceramized
polyolefin material is reasonable in
raw material and proportion, capable of ensuring normal operation of a
route, good in flexibility, simple in process and low in cost.
