Abstract

The invention provides modified mineral fibers for producing a wire insulating layer material, and relates to the technical field of wire and cable production. The modified mineral fibers are prepared from, by weight, 110 parts of mineral fibers, 25 parts of polybutylene terephthalate, 1.5 parts of sodium dodecyl benzene sulfonate, 7 parts of lauramide propyl glycine betaine, 12 parts of anatase titanium dioxide, 3 parts of zinc sulfide, 6 parts of isopropyl lanolate, 11 parts of ethyl laurate, 4 parts of calcium hydrophosphate, 3.5 parts of isopropyl tris (dodecyl benzenesulfonyl) titanate, 0.8 part of dodecyl trimethylammonium chloride, 0.7 part of nickel bis(3,5-di-tert-butyl-4-hydroxy benzylmonoethylphosphonate) and 7 parts of auxiliaries. The surfaces of the modified mineral fibers have ends affinitive to organic matter and are high in compatibility with organic polymers, the interface state is improved, mechanical properties of the composite material can be improved, weather resistance, ageing resistance, heat resistance and the like of the composite material can be remarkably improved, and therefore the modified mineral fibers bring important economic benefits.

Description

technical field

[0001] The invention relates to the technical field of wire and cable production, in particular to a modified mineral fiber for producing wire insulation layer materials. Background technique

[0002] Mineral fiber is a fiber obtained from mineral rocks with a fibrous structure. The main components are various oxides, such as silicon dioxide, aluminum oxide, magnesium oxide, etc., and its main source is various types of asbestos, such as chrysotile and crocidolite. Wait. With good dispersibility and flame retardancy, it is often used as an additive. However, the existing mineral fibers have poor compatibility with organic high polymers, resulting in poor dispersion of mineral fibers in the matrix and easy agglomeration. Therefore, it must be modified to a certain extent. Contents of the invention

[0003] The object of the present invention is to provide a modified mineral fiber for producing wire insulation layer materials to solve the above technical pr...
