In the modern process of the development of human society. The rubber industry is also an indispensable economic industry. In the process of the development of the rubber industry, the progress and development of rubber technology and rubber machinery (or electromechanical) technology have played an important role in promoting. The development of rubber industry, rubber industry technology and rubber machinery technology constitute the entire technical process and industrial technology system of rubber products. In 1820, the United Kingdom made a single-roll rubber mill driven by manpower. In 1826, the double-roller cylinder type open rubber mixing machine was put into production, which opened the prelude to the production of human rubber machinery. So far, the application of rubber machinery in human society has a history of more than 180 years. Since 1839. A series of rubber machinery and equipment have come out, in addition to adapt to the application of rubber vulcanization technology vulcanization equipment, other rubber machinery, such as plunger hose extruder (1858), screw extruder (1879), rubber calender (1843~1900), closed rubber mixing machine (1916). Rubber machinery and equipment, etc. Successively into the rubber industry production process at that time, to promote the development of the rubber industry has played a certain role in promoting. In 1904, the discovery of inorganic vulcanizing agents such as lead oxide and magnesium oxide, especially the discovery and application of organic vulcanization accelerators D and M in 1919, further promoted the progress of production efficiency, greatly improved the performance of rubber products and expanded the scope of use. In 1920, carbon black was added to the rubber to improve the performance of rubber products. Therefore, the application of carbon black has promoted the progress and development of rubber industry. At the beginning and middle of the 20th century, the Soviet Union, the United States, Britain, Germany, France and other countries have invented synthetic rubber industry technology. And set up a series of rubber synthetic production equipment and factories. Coupled with the large-scale production of natural rubber resources in Southeast Asia, it has opened up a material resource base for the development of modern rubber industry.
 

Rubber is a typical material with high elasticity. Its physical properties are very complex. Most rubber processing molding process. There are similar melt activities and deformation processes, and in the processing of rubber products. Raw rubber must go through the process of plasticizing, mixing, pressing, molding, and vulcanizing to become a product. In modern chemical products. Such as rubber, plastic, paint, fiber, lubricants, ceramics and other materials production and engineering technology applications, the complex mechanical properties of the material. Based on pure elastic mechanics, viscous theory or plastic theory. can not meet the deformation requirements of these materials processing process. Therefore, a research topic based on the mechanical properties of complex media, the theory of rheology, has been mentioned in the agenda of the new discipline of human research. In 1928, the United States established the "Rheology Society", and in 1940, the United Kingdom established the Rheology Club (later changed to the Rheology Society). In addition, the Netherlands, West Germany, France, Japan and other countries have also set up a corresponding rheology. The International Rheology Conference was held in 1948. In 1953, the International Rheological Association was established. Since then. A frontier discipline involving applied mathematics, physics, elasticity, material mechanics, fluid mechanics, geology, engineering and other disciplines-rheology came into being and has gradually been widely used. Rheology is not only widely used in the production of rubber, plastics, coatings, printing, silicates, food and other industries, but also involves many industrial parts such as infrastructure, machinery, transportation, water conservancy, and chemical industries: it involves many substances from solid to The change process of liquid. rheology in the rubber industry. Widely used in rubber products processing molding research and application. Such as rubber mixing, calendering, extrusion, injection molding and other processing. Due to its macromolecular chain structure and motion characteristics, the polymer presents four physical states in the physical aggregation state: one crystalline state and three non-crystalline states (glassy state, high elastic state, viscous fluid state). Rubber is highly elastic under normal use. In the process of processing and molding, it is a viscous flow state, and only after vulcanization treatment, it basically loses its activity, and becomes an elastomer material dominated by high elasticity.
