Abstract

The invention discloses modified pyrophyllite for a high-weather-resistance polyethylene cable material and a preparation method thereof. The modified pyrophyllite is prepared from, by weight, 23-37 parts of pyrophyllite, 15-25 parts of sea sand, 8-14 parts of nano hydrotalcite, 4-8 parts of polyisobutylene succinic polyglycerol ester, 3-6 parts of a perfluorinated octane sulfonyl compound, 2-4 parts of white lead powder, 2.5-3.5 parts of di(isooctyl thioglycolate) barium, 5-10 parts of trischloroethyl phosphate, 4-6 parts of sugarcane wax, 3-5 parts of alkali chloride bismuth, 4-7 parts of aluminum tripolyphosphate, 5-10 parts of dicapryl phthalate and 6-9 parts of a compound additive. The modified pyrophyllite is used for filling the polyethylene cable material, the heat aging resistance and weather resistance of the cable material can be significantly improved, the mechanical strength of the cable material can be also improved, the thermal stability of the cable material can be improved, and the chemical corrosion resistance and oil resistance performance and the like of the cable material can be improved.

Description

technical field [0001] The invention relates to a modified pyrophyllite for high weather resistance polyethylene cable material and a preparation method thereof, belonging to the technical field of polymer processing. Background technique [0002] Pyrophyllite is a cheap and easy-to-obtain hydrous aluminosilicate salt mineral with a chemical structure of Al 2 [Si 4 o 10 ](OH) 2 , which has excellent characteristics such as good electrical insulation, acid resistance, high whiteness, and low thermal conductivity, and is widely used as a functional filler for plastic and rubber products. However, the pyrophyllite currently on the market has a low filling function and cannot meet the requirements of multifunctional fillers, which limits the scope of application. Therefore, it is necessary to modify pyrophyllite to improve its comprehensive performance. Contents of the invention [0003] The object of the present invention is to provide a modified pyrophyllite for polyethy...
