Abstract

The invention discloses modified dolomite for a heat-resistant flame-retardant fluoroplastic wire and cable material and a preparation method of the modified dolomite. The modified dolomite is prepared from the following raw materials in parts by weight: 50-70 parts of dolomite, 15-20 parts of barium metatitanate, 18-24 parts of BOVC resin, 10-15 parts of polypentabromobenzyl acrylate, 2-3 parts of bisphenol A bis(diphenyl phosphate), 3-6 parts of white wax, 2-5 parts of niobium diselenide, 5-10 parts of di-iso-decylphthalate, 2.5-4.5 parts of tin antimony oxide, 8-12 parts of silicon powder, 1-2 parts of p-aminophenol, 0.5-1 part of 4-vinylpyridine, 1-2 parts of vitamin C palmitate and 3-5 parts of auxiliaries. The interface performance of the modified dolomite subjected to modification treatment is remarkably improved from hydrophilicity to lipophilicity, so that the compatibility between the modified dolomite with a fluoroplastic base body is strengthened, action between the modified dolomite and high polymer molecules is strengthened and the filling performance of the dolomite is improved, and thus, the integral mechanical performances of the composite material are improved, and the development and application prospect is wide.

Description

technical field [0001] The invention relates to a modified dolomite for heat-resistant and flame-retardant wire and cable materials of fluoroplastics and a preparation method thereof, belonging to the technical field of inorganic fillers. Background technique [0002] Dolomite is a double salt of calcium carbonate and magnesium carbonate, which belongs to the carbonate mineral of trigonal crystal system. Due to its high whiteness, good thermal stability, and low oil absorption, dolomite can be used as a filler to replace some light calcium carbonate, and it can be used as an inorganic reinforcing filler for polymer-based composite materials such as plastics and rubber. However, the surface of the existing dolomite is hydrophilic, while the surface of the polymer matrix is ​​lipophilic. The obvious interface effect between the dolomite and the polymer body will make filling difficult, and the mechanical properties of the filled composite material are not ideal. . Therefore,...
