Abstract

The invention discloses modified montmorillonite for high strength and high toughness polypropylene cable materials and a preparation method thereof, and the modified montmorillonite is prepared from the following raw materials by weight: 100 parts of montmorillonite, 25-45 parts of nano calcium carbonate, 5-10 parts of propylene glycol phenyl ether acetate, 15-25 parts of aluminum silicate, 8-16 parts of basic magnesium sulfate whisker, 5-10 parts of nano carbon fiber, 3-5 parts of 4, 4 '-dihydroxy diphenyl sulfide, 2-4 parts of polyethylene glycol stearate, 1-2 parts of guanidine carbonate, 2-3 parts of tetramethyltetravinylcyclotetra-siloxane, 1-2 parts of lanthanum cyanurate, 0.5-1 part of 3, 4, 5-trimethoxy cinnamic acid, 4-6 parts of liquid paraffin, 2-5 parts of glycerine trioleate and 3-4 parts of an assistant. The modified montmorillonite has excellent dispersion properties and remarkable toughening and reinforcing effect, improves the toughness, meanwhile improves the mechanical strength, impact resistance, fatigue resistance and dimensional stability and the like of the polypropylene cable materials, and does not reduce the processing properties of the materials so as to enhance the comprehensive performances of the polypropylene cable materials.

Description

technical field [0001] The invention relates to a modified montmorillonite for high-strength and high-toughness polypropylene cable material and a preparation method thereof, belonging to the technical field of inorganic fillers. Background technique [0002] Montmorillonite is a representative mineral in clay. The main component is montmorillonite, which is a layered silicate crystal composed of two layers of Si-O tetrahedron and one layer of Al-O octahedron. It is widely used as a filler for polypropylene cable products to improve the physical and chemical properties of composite materials due to its specific surface area, high surface activity and high thermal stability. However, the boehmite currently on the market has low filling function, poor toughening and reinforcing effects, and cannot meet the requirements of multifunctional fillers. Therefore, montmorillonite must be modified. Contents of the invention [0003] The purpose of the present invention is to provid...
