Problems solved by technology
[0004] The commonly used composite materials of rubber and fabric are not strong enough in terms of physical properties, and the flame resistance is not enough, and the finished product needs three times of processing, including first making the first composite material of fabric, then making the second composite material, and then compounding the two The combination of material attachment requires high labor costs in the lamination process, which also requires a long working time and low work efficiency. Moreover, when the vulcanized rubber is bonded to a large area, it is easy to cause poor bonding.

Abstract
The invention provides a manufacturing method of a flame-resistant composite material for connecting expansion joints. The manufacturing method comprises the following steps of: mixing a rubber material by utilizing a million-horsepower machine, calendering the rubber material to be a rubber sheet, calendering the rubber material and basic cloth to be rubber cloth with a two-layer structure, laminating the upper surface and the lower surface of the rubber sheet respectively with the rubber cloth by utilizing a continuous hot-pressing laminating machine to form a composite material structure with five layers, finally sulfurating the composite material structure by utilizing a drum-type continuous sulfurating machine, namely forming the flame-resistant composite material with high physical property, high flame resistance and long service life. The flame-resistant composite material manufactured by the method disclosed by the invention is suitable for the requirements of general vehicles on safety.
Description
technical field [0001] The invention relates to a manufacturing technology of a waterproof membrane material, in particular to a manufacturing method of a fire-resistant composite material used for connecting expansion joints between large buses or train carriages Background technique [0002] Recently, the means of transportation on the road has developed rapidly. Many developing countries or developed countries around the world have used public transportation vehicles in large quantities, and various public transportation vehicles mostly increase the passenger capacity by connecting more than two carriages; such as trains, electric vehicles, etc. Combined trains, MRT, large two-stage connecting buses (there is no such bus in Taiwan, but it is quite common in Europe, America and the mainland), high-speed maglev trains, etc., at first, they only used hooks to connect the carriages. It is convenient for passengers to move between the compartments, and the compartments are des...
