Abstract

The invention discloses modified bauxite for a thermal ageing resistant polyurethane cable material and a preparation method of the modified bauxite. The modified bauxite is prepared from the following raw materials in parts by weight: 55-65 parts of bauxite, 7-13 parts of 4A molecular sieve powder, 5-10 parts of triethyl borate, 2-3 parts of peroxidized di(2-ethylhexyl) dicarbonate, 10-15 parts of calcined pottery clay powder, 8-14 parts of methyl MQ silicon resin, 1.5-2.5 parts of N-phenyl maleimide, 3-5 parts of trihydroxymethylpropyl trioleate, 4-7 parts of divinyl benzene, 5-10 parts of tung oil anhydride, 2-3 parts of cerous fluoride, 2.5-4.5 parts of 3, 3'- dichloro-4,4'- diaminodiphenyl methane, 4-6 parts of isodecyl salicylate, 5-10 parts of butoxytriethyl phosphate, 0.5-1.5 parts of 2-(4-morpholinyldithio) benzothiazole and 3-5 parts of auxiliaries. After being subjected to modified treatment, the bauxite has very good oleophylic and hydrophobic performances, is very easily dispersed in a polyurethane system, and is good in compatibility, high in filling performance, capable of improving performances such as chemical corrosion resistance and heat-proof aging performance while improving the mechanical performances of the polyurethane cable material and wide in application prospect.

Description

technical field [0001] The invention relates to a modified bauxite for heat-resistant aging polyurethane cable material and a preparation method thereof, belonging to the technical field of inorganic fillers. Background technique [0002] The scientific name of bauxite is bauxite, bauxite. Its composition is extremely complex, and it is a general term for a variety of hydrous alumina ores from very different geological sources. Such as boehmite, diaspore and gibbsite; some are composed of diaspore and kaolinite; Soil or kaolinite clay. Bauxite is generally formed by chemical weathering or exogenous action. There are few pure minerals and always contain some impurity minerals, more or less clay minerals, iron minerals, titanium minerals and detrital heavy minerals. Bauxite has the advantages of high strength, high temperature resistance, good thermal stability, strong chemical stability, and good physical properties. It is used as a filler in plastics and rubber to improve...
