Abstract

The invention discloses a modified halloysite for a flame-retardant polypropylene cable sheath material and a preparation method thereof. The modified halloysite is prepared from the following raw materials in parts by weight: 54-68 parts of halloysite, 11-17 parts of acetylenyl cyclohexanol, 4-9 parts of zinc hydroxystannate, 2-3 parts of triglycidyl p-aminophenol, 2.5-4.5 parts of isopropyl palmitate, 1-2 parts of yttrium naphthoate, 10-15 parts of tri-n-hexyl acetylcitrate, 5-10 parts of slaked lime, 8-14 parts of scrap rubber powder, 3-4 parts of butylated hydroxyanisole, 1.5-2.5 parts of stannous pyrophosphate, 10-15 parts of isopropylated triphenyl phosphate, 5-10 parts of tetrabromobisphenol A-bis(2,3-dibromopropyl ether), 1-2 parts of 2- hydroxy-4-methoxy diphenyl ketone, 1-2 parts of 4,4'-dihydroxydiphenyl and 3.5-6.5 parts of assistant. The modified halloysite has the advantages of favorable compatibility with polypropylene, high interfacial binding force and excellent dispersity in the polypropylene base, has an obvious reinforcing action on the polypropylene, enhances the mechanical properties of the polypropylene cable sheath material, and can enhance the thermal aging resistance, abrasion resistance and flame retardancy of the polypropylene cable sheath material.

Description

technical field [0001] The invention relates to a modified halloysite for a flame-retardant polypropylene cable sheath material and a preparation method thereof, belonging to the technical field of inorganic fillers. Background technique [0002] Halloysite is a hydrous layered silicate mineral crystal belonging to the monoclinic crystal system. The crystal structure is similar to kaolinite, and the chemical composition is Al 2 [Si 2 o 5 ](OH) 4 ·(1~2)H 2 O. The use of halloysite is similar to that of kaolinite. It is used as a filler in plastics and rubber to improve the physical and chemical properties of composite materials. The dispersion effect of halloysite in the market is not satisfactory in the polypropylene matrix, and agglomeration is prone to occur, and the interface bonding is not good, which affects the improvement of the performance of composite materials. Therefore, halloysite must be modified. Contents of the invention [0003] The purpose of the pre...
