Description
Technical field
The invention belongs to rubber manufacturing technology field, be specifically related to a kind of preparation method of rubber wick and the application in automobile component thereof.
Background technology
Along with the development of China's automobile industry grows, domestic automobile manufacture in 2011 rough estimates 2,000 ten thousand, account for No. 1 in the world.In order to meeting the market requirement, meet national desire to purchase and requirement, Ge great main engine plants release the new model of fashionable, safety and comfort, moderate cost, environmental protection and energy saving one after another, the requirement of Ge great main engine plants to supplier is more and more higher simultaneously, selection has availability, constant product quality, Technology and equipment advanced person, the supply of material in time, serve, price is low includes matching system in, how to tackle the annual 5%-15% of Ge great main engine plants price reduction index in various degree, deposits opportunity, pressure and challenge automobile component part supply business.
Automobile Design mainly contains four large classes, and many points of parts wherein in engine and chassis are rubber hose, and in these point of part, it important effect to rubber hose.Engine environment has air-conditioning system and heat-removal system, and air-conditioning system and the connecting portion of heat-removal system are connected by rubber hose; The power steering system of chassis portion unifies brake system also by rubber hose connection.Because these rubber product majorities belong to high-voltage product, its product structure design usually adopt two-layer braiding and tension large braiding machine braiding, traditional technology in the past generally adopts steel core mould as the core of sebific duct, if adopt steel core to manufacture sebific duct can only adopt horizontal vulcanizer sulfuration, and horizontal vulcanizer length is the longest namely 20 meters both at home and abroad, that is useful length 20 meters of every root sebific duct.To shorten gradually in Reusability process because hose manufacturing process flow process determines rubber wick, its hose manufacturing process flow process is as follows: sizing material banburying, and--fuse manufacture prepares, and--interior glue is extruded, and----outer glue is extruded, and--sulfuration--depoling--inspection is put in storage in braiding.Sebific duct manufacture just can need complete through multiple working procedure, and rubber wick will shorten gradually after the Reusability of multiple working procedure, if short rice rubber wick cannot be connected as one, increase core length, then short rice fuse can only scrap process.The external diameter of rubber wick i.e. the internal diameter of sebific duct, rubber wick outside dimension directly affects the internal diameter size of sebific duct, short rice fuse interior glue extrude extrude with outer glue time size fluctuation large, size is difficult to control, and indirectly have impact on internal diameter size and the end product quality of sebific duct, if fuse is short, fuse radical is then more, and sebific duct stub bar is then more, wastes then larger, cost is higher, in the same industry, do not have competitive power.
