The invention discloses a modified
sericite for an
impact-resistant
polyolefin cable material and a preparation method thereof. The modified
sericite is prepared from the following raw materials in parts by weight: 70-80 parts of
sericite, 14-22 parts of
molybdenum boride, 10-15 parts of triglyceryl trimellitate, 12-18 parts of gas-phase
silicon dioxide, 7-13 parts of carbon
fiber powder, 3-5 parts of polymerized
rosin, 2-3 parts of 2,5-ditert-butylhydro
quinone, 4-6 parts of
rice bran wax, 5-10 parts of
dimethyl oxalate, 8-12 parts of 2,4,6-tribromophenyl
acrylate, 2-4 parts of hydroxy
aluminum distearate, 4-6 parts of dimethylpropane
carboxylate, 2-3 parts of
ytterbium oxide, 3-5 parts of ethyl diethylaminomethacrylate, 1-2 parts of
zinc pyrithione, 4-8 parts of
bisphenol A
epoxy chloropropane
polymer isostearate and 3-6 parts of assistant. The modified sericite has favorable
interfacial bonding property with the
polyolefin material, higher compatibility with the
polyolefin material and higher
dispersity in the polyolefin base, thereby enhancing the filling effect of the sericite; and thus, the polyolefin cable material has the advantages of higher tensile strength, higher
impact strength, higher elongation at break, excellent
heat resistance, excellent
wear resistance and excellent
corrosion resistance.
