The main production process of rubber products

Mixing

In order to adapt to various use conditions, obtain various properties, and to improve the performance of rubber products and reduce costs, different compounding agents must be added to the raw rubber. Mixing is a process in which the plasticized raw rubber is mixed with the compounding agent, placed in the rubber mixing machine, and the compounding agent is completely and uniformly dispersed in the raw rubber through mechanical mixing. Mixing is an important process in the production process of rubber products. If the mixing is not uniform, the role of rubber and compounding agents will not be fully utilized, which will affect the performance of the product. The rubber compound obtained after mixing is called compound rubber. It is a semi-finished material for the manufacture of various rubber products, commonly known as rubber compound, and is usually sold as a commodity. Need rubber products. According to different formulations, there are a series of different grades and varieties of rubber compounds with different properties, and options are available.

Forming

In the production process of rubber products, a calender or extruder is used to pre-make a process of various shapes and sizes, which is called molding. The forming methods are:

Calendering is suitable for the manufacture of simple sheet and plate products. It is a method of pressing the rubber compound into a film of a certain shape and a certain size through a calender, called calendering. Some textile fiber materials used in rubber products (such as tires, rubber cloth, hoses, etc.) must be coated with a thin layer of glue (gluing on the fiber is also called glue or rubbing), and the gluing process is generally completed on the calender. The fiber material needs to be dried and dipped before calendering. The purpose of drying is to reduce the moisture content of the fiber material (to prevent water from evaporating and foaming) and to increase the temperature of the fiber material to ensure the quality of the calendering process. Glue dipping is a necessary process before gluing, and the purpose is to improve the bonding performance of fiber materials and rubber materials.

Extrusion molding is used for more complex rubber products, such as tire treads, rubber tubes, and metal wire surface coatings that need to be manufactured by extrusion molding methods. It is a method in which a rubber compound with a certain degree of plasticity is put into the hopper of an extruder, and under the extrusion of a screw, it is a method of continuous molding through various mouth shapes (also called templates). . Before extruding, the rubber material must be preheated to make the rubber material soft and easy to extrude, so as to obtain rubber products with smooth surface and accurate size.

Compression molding can also be used to manufacture some complex shapes (such as cups, sealing rings) rubber products, with the help of the formed female and male molds, the rubber material is placed in the mold for heating and forming.

Vulcanization

The process of converting plastic rubber into elastic rubber is called vulcanization. It is to add a certain amount of vulcanizing agent (such as sulfur, vulcanization accelerator, etc.) to the semi-finished product made of raw rubber (carried out in a vulcanizing tank). Heat and keep warm at temperature, so that the linear molecules of the raw rubber are cross-linked into a three-dimensional network structure through the formation of "sulfur bridges", thereby turning the plastic rubber into a vulcanized rubber with high elasticity. Since the cross-linking bond is mainly composed of sulfur, it is called "vulcanization". With the rapid development of synthetic rubber, there are now many varieties of vulcanizing agents, in addition to sulfur, there are organic polysulfides, peroxides, metal oxides and so on. Therefore, any process that can transform the linear structure of plastic rubber into a three-dimensional network structure of elastic rubber is called vulcanization, and any substance that can act as a "bridging" in the rubber material is called a "vulcanizing agent."

The vulcanized elastic rubber is called vulcanized rubber, also called soft rubber, commonly known as "rubber". Vulcanization is one of the most important processes in rubber processing, and various rubber products must be vulcanized to obtain ideal performance. Unvulcanized rubber has no use value in use, but under-sulfur (the degree of vulcanization is not enough, the vulcanization time is not enough, and the best state is not reached) and over-sulfur (the vulcanization time is exceeded, the performance is significantly reduced), both make the rubber Performance drops. Therefore, the vulcanization time must be strictly controlled during the production process to ensure that the vulcanized rubber products have the best performance and the longest service life.
