Amino Silane Coupling Agent in different industries have different name, such as in the rubber industry is called "vulcanizing Agent", known as the "Agent" in the plastic industry, the curing Agent, curing Agent, known as the "Agent" in the adhesive industry. But its meaning is to make linear polymer cross - linking into network structure.
The so-called "cross-linking" refers to the linear polymer to shape the role of the polymer structure, those that plays a role of bridge between the molecules, hasten the role or substance, called Amino Silane Coupling Agent.
Amino Silane Coupling Agent is used to crosslink polymers by forming chemical bonds. The basic bonds that produce crosslinks can be divided into three categories:
1. The polyacrylamide is crosslinked by polar bonds, such as formaldehyde.
2. Cross-linked by ionic bonds, such as barium chloride cross-linked with sodium alginate;
3. Polyacrylamide is crosslinked with polyacrylamide through the covalent bond to produce multi-nucleated hydroxy-bridge ions, such as zirconium.
But more crosslinking is produced by two kinds of chemical bonds, such as boric acid will galactomannan crosslinked by polar bond and coordinate bond, complex ion by multi-core hydroxyl chromium bridge will sodium carboxymethyl cellulose is crosslinked by ionic bond and coordination bond, etc.
Amino Silane Coupling Agent is required for the preparation of gelled acid and water-based gel-gel fracturing fluid, in addition to the need for thickening Agent.
In our industrial production at present, the commonly used Amino Silane Coupling Agent are: organic peroxides, amine, oxime, organic sulfide, phenol resin and organic dibasic acid, polyol, molecular contains more unsaturated double bond compounds and more mercapto polymers, such as Amino Silane Coupling Agent at room temperature performance is very stable, long-term storage at room temperature. The functional groups of TAIC are three allyl groups, which have the general properties of aliphatic olefin.
