The bonding process of heat-resistant conveyor belts in production is one of the important factors affecting the bonding effect of conveyor belts. If the bonding process is not proper, it is easy to cause the heat-resistant conveyor belt to tear and open, which greatly shortens the service life. The following conveyor belt manufacturers take a detailed look at the bonding process of heat-resistant conveyor belts.
The heat-resistant conveyor belt agent bonding process generally includes surface treatment, gluing, drying, gluing, curing, etc. of the adherend, which is relatively complicated and has many influencing factors. Therefore, the bonding must be performed according to the correct process; Properties, which share interlayer cations and are compact with each other, a series of composite materials of clay polymer nanorubbers with excellent properties are prepared, and the so-called intercalation compounding inserts monomers or polymer molecules into the layered silicate In the nano-space between the layers, the layered silicate is peeled into nano-structure units or micro-regions by polymerizing or shearing force and uniformly dispersed in the polymer matrix.
The direct adhesion method of heat-resistant conveyor belt refers to the method of directly adding adhesives to the rubber compound and curing the interface by vulcanization to achieve bonding. Commonly used direct bonding systems mainly include methylene white, organic cobalt salts, and over-vulcanization stability Agent, white carbon black and other systems, antioxidants can improve the adhesion of rubber and steel wire while protecting, and cobalt salt of organic acid can act as an adhesion promoter when bonding rubber to brass or galvanized steel cord or rope. . The intercalation composite method is a method for preparing polymer layered silicate nanocomposites. First, a monomer drum polymer is inserted between the layered silicate sheets treated with an intercalator, thereby destroying the silicate sheets. The layer structure makes it peel off to become the basic unit of layered silicate, and is evenly dispersed in the polymer matrix, so as to realize the composite of polymer and clay-like layered silicate on the nanometer scale.
