Abstract

The invention discloses modified fibrolite for a high-temperature-resistant polyvinyl chloride cable material and a preparing method thereof. The modified fibrolite is prepared from, by weight, 30-40 parts of fibrolite, 16-24 parts of flint clay, 10-15 parts of bauxite, 5-10 parts of lithopone, 5-10 parts of crystalline graphite powder, 4-8 parts of diphenylmethane bismaleimide, 6-12 parts of trioctyl trimellitate, 5-10 parts of dioctyl azelate, 2-4 parts of pentaerythritol monolaurate, 1-2 parts of lithium 12-hydroxystearate, 3-6 parts of poly-alpha-olefin, 1-2 parts of zinc dibutyl dithiocarbamate, 1-2 parts of diallyl bisphenol A and 4-8 parts of compound additive. The modified fibrolite has excellent high temperature resistance and the excellent mechanical performance; meanwhile, binding with an interface of a high polymer matrix is good, the heat stability, the wear resistance, the chemical corrosion resistance and the aging resistance of a composite material can be improved, and the service life of the material is prolonged.

Description

technical field [0001] The invention relates to a modified suviferite for high temperature resistant polyvinyl chloride cable material and a preparation method thereof, belonging to the technical field of polymer processing. Background technique [0002] Also called sillimanite or sillimanite, sillimanite is a brown, light green, light blue or white glassy silicate mineral that is widely distributed. Commonly found in the contact zone between igneous rocks (especially granite) and aluminum-rich rocks and in areas where schist and gneiss are developed. Sulverite has unique performance characteristics, making it have good chemical stability, heat resistance, thermal shock resistance, mechanical properties, etc., and is widely used as a filler for plastic and rubber products. However, the current suvite on the market has a low filling function, which cannot meet the requirements of multi-functional fillers, which limits the scope of application. Therefore, it is necessary to m...
