What is the direct adhesion of heat-resistant conveyor belts?

1. There are three theoretical explanations for the bonding mechanism of high-quality heat-resistant conveyor belt adhesives, namely adsorption theory, electrostatic theory and diffusion theory. The products are mainly used for bonding between two-phase solid surfaces, usually by spraying, coating and pasting. For the purpose of bonding, the bonding process is one of the main factors affecting the adhesion of the adhesive. If the bonding process is not good, the best adhesive can not achieve a good bonding effect. The adhesive bonding process generally includes the surface treatment of the adherend. Gluing, drying, gluing, curing, etc., are more complicated and have many influencing factors, so they must be bonded according to the correct process; people use the speciality of clay structure, which shares the interlayer cations with each other and compacts, and prepares a series of A composite of clay polymer nano-rubbers with excellent properties, and the so-called intercalation compounding inserts monomer or polymer molecules into the nano-space between layered silicate layers, using layers of polymerized ripening or shearing force The silicate is stripped into nanostructured units or domains and uniformly dispersed into the polymer matrix.

2. The direct adhesion method of the heat-resistant conveyor belt refers to the method of directly adding the adhesion aid to the rubber compound, and bonding the interface to bond by vulcanization. The commonly used direct adhesion system mainly has a white, organic cobalt salt, and Vulcanization stabilizer, white carbon black and other systems, the anti-aging agent can improve the adhesion of rubber and steel wire while protecting. The organic acid cobalt salt acts as a adhesion promoter when bonding rubber and brass or galvanized steel cord or rope. The role.

3. Intercalation composite method is a method for preparing polymer layered silicate nanocomposites. First, the monomer drum polymer is inserted between the layered silicate sheets treated by the intercalation agent, thereby destroying the silicate. The lamellar structure is stripped into a basic unit of layered silicate and uniformly dispersed in the polymer matrix to achieve the composite of the polymer and clay layered silicate on the nanometer scale.
