Composite Rubber Bands Will Be Mainstream

The technical analysis of the development process of rubber belt nanocomposites is as follows: People use the specificity of clay structure, which shares the interlayer cations with each other and compacts, and prepares a series of composite materials of clay polymer nano rubber with excellent properties, so-called Intercalation recombination involves inserting monomer or polymer molecules into the nanospace between the layered silicate layers, and separating the layered silicate into nanostructured units or domains by polymerization or shearing force to uniformly disperse Into the polymer matrix;


    The intercalation composite method is a method for preparing a polymer layered silicate nanocomposite. First, a monomer drum polymer is inserted between the intercalated layered silicate layer, thereby destroying the silicate sheet. The layer structure is stripped into a basic unit of layered silicate and uniformly dispersed in the polymer matrix to realize the composite of the polymer and the clay layered silicate on the nanometer scale;


    ZT belting rubber conveyor belt manufacturers have divided the intercalation composite method into two categories according to the process of compounding rubber materials:


     1) Intercalation polymerization: The polymer monomer is first dispersed, intercalated into the layered silicate layer, and then polymerized in situ to overcome the force between the silicate sheets by utilizing a large amount of heat released during the polymerization. Stripping it so that the silicate layer is composited with the polymer matrix at a nanoscale;


    2) Polymer intercalation: mixing polymer melt or solution with layered silicate, using force chemistry or thermodynamics to strip layered silicate into nano-scale sheets and uniformly disperse in the polymerization of conveyor belt rubber In the matrix


    At the same time, according to the type of polymerization reaction, the intercalation polymerization is divided into two types: intercalation polycondensation and intercalation polyaddition, and polymer intercalation can be divided into polymer solution intercalation and polymer fusion intercalation. From a structural point of view, polymer layered silicate nanorubber composites are classified into two types, intercalated nanocomposites and exfoliated nanocomposites, in intercalated polymer layered silicate nanocomposites. The intercalation of the polymer into the silicate layer, although the interlamellar spacing of the silicate is enlarged, but the layer still has a certain order, in the exfoliated nanocomposite, the silicate layer Disrupted by the polymer, randomly dispersed in the polymer matrix is a piece of silicate unit sheet, at which time the silicate layer and the polymer achieve uniform mixing on the nanometer scale, due to the heat-resistant conveyor belt The polymer chain is greatly different between the inter-layer confined space and the extra-layer free space. Therefore, the intercalated polymer nanocomposite can be used as an anisotropic functional material, and the exfoliated polymer layered silicate nanometer. Composite materials have very The enhancement effect;
