Take you to know the common titanate coupling agent of calcium carbonate (CaCO3)
Original title Take you to know the Titanium 6Al4V wire common titanate coupling agent of calcium carbonate (CaCO3) I Overview Titanate ester coupling agent has been developed into a new type of coupling agent system parallel to silicon coupling agent since it was first reported publicly by Ken Petrochemical Company (Richpetrocheoical Co) in the United States at the end of 1984 As a molecular bridge connecting inorganic fillers and organic polymers it has fully demonstrated its excellent performance and has been widely used in various fields of polymer synthetic materials such as resins coatings rubbers and plastics With the development of contemporary synthetic materials from single organic polymer to organic and inorganic polymer composite people put forward endless requirements for coupling agents and other additives but the renewal and innovation of coupling agents give new nickel titanium wire vitality to composite materials In this paper the preparation methods functions and applications of coupling agents are briefly introduced II Preparation method of iron-based coupling agent In short the titanium-based coupling agent is obtained by reacting a Titanic acid lower ester with a fatty acid having a higher carbon number or a fatty alcohol In which that low ester of titanate may be tetraisopropyl titanate tetra-n-butyl titanate tetra-tert-butyl titanate and the like They are made by the reaction of titanium chlorides with the corresponding monohydric alcohols; high-carbon-number fatty acids are generally referred to as Cg or more fatty acids usually C12 to C18 fatty acids such as lauric acid tridecanoic acid myristic acid palmitic acid pearlescent acid stearic acid and other saturated monobasic acids and oleic acid acrylic acid and other unsaturated monobasic acids can also be mixed acids At present there are few data and patent reports on the preparation of titanium-based coupling agents and only some preparation methods of Titanic acid lower esters have been preliminarily found Therefore this paper can only slightly mention the principle preparation method of titanium-based coupling agent after describing the preparation method of Titanic acid lower ester 1 Preparation of Titanic acid lower ester Titanate lower esters are formed by the reaction of titanium chlorides with the corresponding monohydric alcohols (1) general preparation A few examples are listed below and briefly explained
