Production process of rubber air springs

Rubber air springs are the inevitable trend of today's automotive equipment development, matching and industrial equipment accessories. With the current development of the world's automobile industry in the direction of high speed, high performance, comfort, safety and reliability, and convenient maintenance, steel plates and gas springs have become more and more unsuitable for its development, while rubber air springs can well meet its needs. For example, in Europe, the penetration rate of rubber air springs has basically reached 70-80%. High-quality rubber air springs go through the following steps. 

1. Rubber mixing
2. Cord calendering
1) Cord: nylon 6, 66, modified 66. Polyester cord (PET) cord has single strand, 2 strands, 3 strands. Normal, bold.
2) Equipment:
Four-roll calender calendering line,.
The calendering process is a process of using a calender to cover the surface of the textile with the compounded rubber, and penetrate into the inside of the fabric gap, so that the rubber and the textile are tightly combined to form a rubber cord.
There are three ways to hang fabrics:
a.-General glue calendering;
b. Pressure glue calendering;
c. Rubbing and calendering.
Process performance requirements of the calendering compound:
It should have suitable rollability, good fluidity, sufficient scorch resistance and low shrinkage. Appropriate wrapping properties: The rubber material can neither be taken off the roll nor stick to the roller on the calender roll, but it should be convenient for the calendering operation and easy to produce sheets; good fluidity: the rubber material can penetrate smoothly and evenly into the Between the cords; Sufficient scorch resistance: The rubber compound must be heat-smelted before calendering and subjected to multiple thin passes, and it is often carried out at a higher temperature (80-110°C) during calendering, so the rubber. There should be no scorch during the calendering process. Low shrinkage: The elastic deformation of the rubber should be reduced, so that the surface of the rubber curtain does not change much after calendering.
3. Film calendering
The film required for the production of air springs is generally calendered with a three-roll calender. The hot-melted rubber material is pressed into a sheet of a certain thickness by three rolls, and is cooled by a conveyor belt and rolled into a roll. The width of the film is generally in the rollers. The width of the upper cutting edge is fixed, and the edge is not cut during molding. .According to its own functional requirements, the air spring has better air tightness of the inner film,
Therefore, butyl rubber is used in the formulation design; while the outer layer film requires weather resistance and good fatigue resistance, and chlorine-J rubber is used in the formulation design.
