Abstract

The invention discloses a modified attapulgite for an outdoor aerial cable material and a preparation method thereof. The modified attapulgite is prepared from, by weight, 26-38 parts of attapulgite, 10-15 parts of pebble chips, 5-10 parts of nano molybdenum powder, 4-8 parts of anatase titanium dioxide, 2-4 parts of 3- isocyanatepropyltriethoxy silane, 1-2 parts of dibutyltin dilaurate, 3-4 parts of soya bean lecithin, 2-3 parts of tripolyglycerol monostearates, 1-2 parts of ethylhexyl salicylate, 0.5-1 part of tocopherol acetate, 1-2 parts of 2-phenyl benzimidazole-5-sulphonic acid, 3-5 parts of bismuth molybdate and 4-6 parts of a compound additive. The prepared attapulgite is applied to the outdoor aerial cable material, can have higher mechanical strength and can also have excellent weather resistance, aging resistance and oxidation resistance.

Description

technical field [0001] The invention relates to a modified attapulgite for outdoor overhead cable materials and a preparation method thereof, belonging to the technical field of polymer processing. Background technique [0002] Attapulgite, referred to as attapulgite or attapulgite, belongs to the sepiolite family in mineralogy, and its chemical formula is: Mg 5 (H 2 O) 4 [Si 4 o 10 ] 2 (OH) 2 , is a kind of hydrous-rich magnesium aluminum silicate clay mineral with layer chain molecular structure with unique properties. Its crystal structure is fibrous or narrow band with a high aspect ratio. Due to the unique crystal structure of attapulgite, it has many special physical, chemical and technological properties, such as unique dispersion, high temperature resistance, salt and alkali resistance, etc. Widely used as filler for plastic and rubber products. However, attapulgite currently on the market has a low filling function and cannot meet the requirements of multifu...
