Abstract

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.

Description

technical field [0001] The invention relates to a modified sericite for impact-resistant polyolefin cable material and a preparation method thereof, belonging to the technical field of inorganic fillers. Background technique [0002] Sericite is a kind of natural fine-grained muscovite, which belongs to the subspecies of muscovite. It is a silicate mineral with a layered structure. . Sericite has the characteristics of high diameter-to-thickness ratio, high elasticity, flexibility, good abrasion resistance and abrasion resistance, good electrical insulation, insoluble in acid-base solutions, and stable chemical properties. It is a natural functional powder. Filling material, widely used in plastics, rubber and other fields. Ordinary sericite is a hydrophilic inorganic filler, which is different from the interface properties of polymer materials and has poor compatibility. Therefore, it is necessary to modify sericite to improve the filling effect of sericite. [0003] C...
