Technical Field

The invention belongs to the technical field of automobile parts, and particularly relates to a preparation method of an automobile engine belt.

Background

An Engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including, for example, internal combustion engines (reciprocating piston engines), external combustion engines (stirling engines, steam engines, etc.), jet engines, electric motors, etc. Such as internal combustion engines, typically convert chemical energy into mechanical energy. The engine is suitable for a power generation device, and can also refer to the whole machine (such as a gasoline engine and an aircraft engine) comprising the power device. Engines were first introduced in the united kingdom, and the engine concept is also derived from english, which is meant in its meaning as "power generating machinery". Belt products are widely used in various industrial places as conveying parts, packaging parts, friction parts and the like; the belt is generally made of rubber, plastic, leather, or the like, depending on the material. The power needs to be transmitted through the belt, but the existing belt has general mechanical properties and short service life.
